Reducing damaging “ultra-emission” methane leaks could soon become much easier–thanks to a new, open-source tool that combines machine learning and orbital data from multiple satellites, including one attached to the International Space Station.

Methane emissions originate anywhere food and plant matter decompose without oxygen, such as marshes, landfills, fossil fuel plants—and yes, cow farms. They are also infamous for their dramatic effect on air quality. Although capable of lingering in the atmosphere for just 7 to 12 years compared to CO2’s centuries-long lifespan, the gas is still an estimated 80 times more effective at retaining heat. Immediately reducing its production is integral to stave off climate collapse’s most dire short-term consequences—cutting emissions by 45 percent by 2030, for example, could shave off around 0.3 degrees Celsius from the planet’s rising temperature average over the next twenty years.

Unfortunately, it’s often difficult for aerial imaging to precisely map real time concentrations of methane emissions. For one thing, plumes from so-called “ultra-emission” events like oil rig and natural gas pipeline malfunctions (see: Turkmenistan) are invisible to human eyes, as well as most satellites’ multispectral near-infrared wavelength sensors. And what aerial data is collected is often thrown off by spectral noise, requiring manual parsing to accurately locate the methane leaks.

A University of Oxford team working alongside Trillium Technologies’ NIO.space has developed a new, open-source tool powered by machine learning that can identify methane clouds using much narrower hyperspectral bands of satellite imaging data. These bands, while more specific, produce much more vast quantities of data—which is where artificial intelligence training comes in handy.

The project is detailed in new research published in Nature Scientific Reports by a team at the University of Oxford, alongside a recent university profile. To train their model, engineers fed it a total of 167,825 hyperspectral image tiles—each roughly 0.66 square miles—generated by NASA’s Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) satellite while orbiting the Four Corners region of the US. The model was subsequently trained using additional orbital monitors, including NASA’s hyperspectral EMIT sensor currently aboard the International Space Station.

The team’s current model is roughly 21.5 percent more accurate at identifying methane plumes than the existing top tool, while simultaneously providing nearly 42 percent fewer false detection errors compared to the same industry standard. According to researchers, there’s no reason to believe those numbers won’t improve over time.

“What makes this research particularly exciting and relevant is the fact that many more hyperspectral satellites are due to be deployed in the coming years, including from ESA, NASA, and the private sector,” Vít Růžička, lead researcher and a University of Oxford doctoral candidate in the department of computer science, said during a recent university profile. As this satellite network expands, Růžička believes researchers and environmental watchdogs will soon gain an ability to automatically, accurately detect methane plume events anywhere in the world.

These new techniques could soon enable independent, globally-collaborated identification of greenhouse gas production and leakage issues—not just for methane, but many other major pollutants. The tool currently utilizes already collected geospatial data, and is not able to currently provide real-time analysis using orbital satellite sensors. In the University of Oxford’s recent announcement, however, research project supervisor Andrew Markham adds that the team’s long-term goal is to run their programs through satellites’ onboard computers, thus “making instant detection a reality.”

The end is nigh for many Google accounts. Beginning on December 1, “inactive” accounts that haven’t been logged into within the last two years will begin disappearing as part of a purge announced by the company back in May. This means any unused accounts’ emails, photos, videos, and documents spread across Google products like Gmail, Docs, Drive, Calendar, Meet, and Photos could disappear as soon as this weekend.

That said, the move shouldn’t come as a surprise. Since revealing its plans earlier this year, Google says it sent multiple notifications to applicable users, both to any account’s Gmail address, as well as any available associated recovery emails.

[Related: The US antitrust trial against Google is in full swing. Here’s what’s at stake.]

The reasoning behind trashing unused accounts is, simply put, security. According to Google, bad actors are as much as 10 times more likely to gain access to abandoned accounts than active accounts utilizing protective measures like 2-step-verification. Once compromised, the hijacked accounts can be then harnessed to send malware, spam, and even aid in identity theft.

Google won’t slash its list of inactive accounts in one fell swoop, however. First up will be any accounts that were never used after being created, followed by a phased approach to tackle the rest “slowly and carefully,” according to the May announcement.

To spare your rarely-if-ever used account from the culling, all users need to do is simply sign in at least once before December 1. That’s enough to reset Google’s activity threshold, and stave off an automatic deletion. Using Gmail, accessing Google Drive, watching YouTube videos while logged in, or even signing into a third-party app using your Google Account all count as activity, as well.

Currently, the purge only concerns personal Google accounts. School, work, and official organizational accounts are not in danger come December 1, as well as those accounts with linked, active subscription plans set up through news outlets or apps. Google also does not currently plan to delete any accounts hosting YouTube videos, either.

[Related: How to back up and protect all your precious data.]

If nothing else, the mass deletion campaign can serve as a helpful reminder to log into old accounts, update passwords, establish two-factor authentication protocols, and download backups of any old uploaded content or data. The easiest way is to head over to the Google Takeout page and follow its instructions for exporting data.

Entry-level motorcycles too often feel like beginner bikes. Even if they don’t have training wheels, they have the vibe of first bicycles that are quickly outgrown and forgotten.

BMW has escaped this trap with the G 310 R, which is an ideal starter bike because of its affordable $4,995 price tag, its rider-friendly low seat that makes it easier to plant both feet on the ground, and its 349-lb. curb weight. The company even trimmed its regular $495 destination fee to $245 to help keep the price within reach for buyers on a budget.

BMW tells me that the G 310 R is a favorite at Motorcycle Safety Foundation’s Basic RiderCourse. It is easy to see why, considering the bike’s combination of racy styling and ease of use.

But anyone who decides to start out on a G 310 R shouldn’t feel like it is a temporary ride, waiting to be replaced by a “real” bike once the owner gains some experience. That’s because the G 310 R provides “real” big technology like standard anti-lock brakes (ABS) and a sophisticated suspension that includes an inverted fork for the front wheel and a long-wheelbase cast aluminum swingarm for the rear.

Inverting the fork (also called “upside down” forks”) bolts the heavy forks sliders into the triple clamps that secure them to the bike’s steering head, leaving the lightweight tubes to stretch down to the axle. That leaves the lighter tubes as the unsprung mass that has to travel up and down with the road surface while the heavier part is fixed in place. This contributes to more responsive front suspension.

Meanwhile, the lengthy swingarm to the rear axle lends the bike greater stability compared to a short swingarm.

The value of anti-lock brakes should be self-evident, but to recap, the BMW’s computer prevents riders from locking a wheel under heavy braking. In a car, this produces a slide and prolongs stopping distances. On a bike, if the front wheel locks, it tends to immediately slip to one side or the other and pitch the rider to the ground. 

If the rear wheel locks, the bike will start to slide sideways. Riders’ typical response to this is to release pressure to the rear brake. Doing so while the bike is not pointed in the direction of travel when the rear tire regains traction causes the bike to catapult the rider off in a spectacular and painful “high side” crash. 

ABS is worth its weight in cryptocurrency because it prevents both kinds of crashes by ensuring that the wheels keep turning until the bike comes to a complete stop. It is also important because most riders, when faced with a potential crash, fail to apply the brakes hard enough. Ideally, knowing that they can’t lock the brakes will encourage more riders to brake harder so that maybe more of them will stop short of hitting the obstacle ahead.

Regardless, riding the Cosmic Black G 310 R test bike was enough fun to put such sober considerations in the background. I had the opportunity to test it alongside BMW’s sexy S 1000 R and I can confirm that the smaller bike held its own while slicing through mountain switchbacks, courtesy of its advanced suspension and light weight.

It also highlighted the G 310 R’s user-friendliness. While the S 1000 R has a very abrupt clutch friction point and brakes that grab aggressively with the slightest application of pressure (very much like Ferrari’s brakes), the G 310 R has a wide, easy-to-engage clutch friction point and brakes that grip progressively, making it very easy for even beginning riders to pull away from a stop and then arrive at the curb like pros instead of the amateurs they are.

Like most of today’s generation of starter bikes, the G 310 R has only one cylinder in its 313-cc engine, when earlier small bikes would have had smoother-running twin-cylinder engines. But the BMW’s 34-horsepower single incorporates a counterbalancer, so it revs to its surprisingly high 9,500-rpm redline with unexpected smoothness. This makes it easier to keep the engine spinning out as much power as possible while clicking through the six-speed transmission, letting the G 310 R feel adequately powerful.

The bike’s engine has an unorthodox configuration, with the cylinder tilting rearward like the back half of a Harley-Davidson V-twin. As with the Harley’s rear cylinder, that puts the BMW’s intake system in front, with the exhaust pipe trailing off the rear, which is the opposite of most single-cylinder bikes.

The rear-leaning cylinder lets the bottom of the engine and the heavy transmission shafts that live there slide forward, shifting the bike’s balance onto the front wheel for greater stability. It also clears space behind the transmission for the aforementioned long rear swingarm.

All of this speaks to the benefit of rethinking the engineering challenge from the beginning of a project and dismissing convention to deliver a superior result. The G 310 R is fun to ride for riders of all levels, not just beginners. But it treats them especially well, just as the Motorcycle Safety Foundation’s rider’s school. The BMW engineer team should be proud of their clever solutions to creating an affordable bike that is a true BMW.

This article was originally featured on Undark.

Twice each year, members of a subspecies of red knots—salmon-colored sandpipers—migrate thousands of miles between their wintering grounds in northern Mexico and breeding sites in the Arctic tundra, encountering myriad obstacles along the way. Thought to migrate during both day and night, brightly lit cities likely disrupt their nighttime journeys, and rising sea levels and invasive species threaten the wetlands they rely on for refueling at stopover sites.

The red knot is one of some 350 North American bird species that migrate. Yet there remains much to learn about the details of their journeys. It’s a critical information gap given the loss of an estimated 3 billion birds in North America since 1970, according to a 2019 study.

“The only way to think about conservation of migratory birds is to consider their full annual cycles,” including their migration routes and wintering sites, said Bill DeLuca, a senior migration ecologist with the National Audubon Society.

The problem, he said, is “We don’t know, for a lot of species, what time of the year is causing the declines.” For the vast majority of migrating birds, the full picture of their life cycle is incomplete, DeLuca added.

That’s partly due to technology. Until recently, while scientists could study birds at their North American breeding sites, they had few ways to track them individually throughout their migrations or while in their wintering grounds, especially small songbirds like warblers and sparrows.

And for birds that migrate through the West’s remote deserts and mountains and across its wild shorelines, like the rufous hummingbird, which journeys between Alaska and the Pacific Northwest and Mexico, their flight routes are even less understood. “Knowledge of migration patterns for birds in the West is way behind the East,” said Mary Whitfield, research director at the California nonprofit Southern Sierra Research Station, because of the smaller number of long-term banding stations there.

But scientists across the West are increasingly turning to an accessible, low-cost technology to answer key questions about bird migration and how climate change is impacting their life cycles.

The Motus Wildlife Tracking System, launched in 2014, is an international network of about 1,800 radio receiver stations in 34 countries. The program, run by the conservation organization Birds Canada, is already well established in eastern North America, but has begun to spread rapidly across the West in the last couple of years. Researchers in the Motus network track birds (or other animals, like butterflies) using small tags. When a bird flies within range of a station—up to about 12 miles away, depending on the conditions—the tag automatically transmits a signal to a receiver, which is then uploaded to the Motus website. Scientists participate through tagging, building Motus stations, or both, and fund their own projects. Museums, zoos, and schools may also participate by hosting a Motus station and educating the public about bird migration and movement, Whitfield noted. So far, more than 43,600 animals, including butterflies, bats, and birds, have been tagged by researchers using Motus globally.

Until recently, tracking tags were too large and heavy for small songbirds. The Motus system uses tags that weigh less than 3 percent of a bird’s weight—in the case of a small songbird that weighs around 18 grams, a tag weighs just half a gram. After birds are captured in mist nets made of fine mesh, they are fitted with the tags using a harness, which they wear like a backpack.

An estimated 1 billion birds use the Pacific flyway, a route through Western coastal states, during their migration, and many millions more migrate via the central flyway through the interior West. Along the way, they routinely encounter natural phenomena like storms, drought, and predators, as well as man-made obstacles like glass-facades that attract birds and pose serious collision risks. In addition, given the rapid growth of wind and solar projects across the West, Whitfield said, it’s crucial to identify birds’ movements through desert areas earmarked for alternative energy development.

According to Whitfield, Motus (Latin for motion) could be a “game changer” for understanding Western birds’ movements through the seasons. “It’s critical,” Whitfield said. “We have to find out more about migration, because it’s definitely a pinch point for bird mortality—that’s typically when birds die the most, because it’s just a really perilous journey.”

In May of this year at the Bosque del Apache Wildlife Refuge in New Mexico, Matt Webb, an avian ecologist with the Bird Conservancy of the Rockies, was getting ready to install a Motus radio tower with funding from the U.S. Fish and Wildlife Service. He hoped to fill “in some of the knowledge gaps” about grassland songbirds, which are experiencing rapid declines in population. Four species in particular have declined more than 70 percent since 1970, according to the bird conservation network Partners in Flight.

Grassland birds range from the prairies of Saskatchewan to the southernmost edges of the Chihuahuan desert in Mexico. “We’ve got this massive geography that we need to cover adequately” to understand their migration, Webb said.

And the birds don’t just travel during migration, he added—they roam widely during both the breeding season and winter, making them even more difficult to monitor. With data from Motus, Webb said, they hope to “unravel some of those mysteries of why they’re moving around and where they’re going during those seasons.”

Webb was equipped with several long antennas and a shoebox-sized, solar-powered sensor station computer with cellular connectivity for receiving and transmitting data. But the road to the tower site was flooded, after increased snowpack drove high flows in the Rio Grande River.

So Webb and Kylie Lamoree, another Bird Conservancy ecologist, turned to Plan B, surveying old water and communications towers as potential locations. In order to detect tagged birds up to 12 miles away, “We need to get it up above the topography and the vegetation nearby,” Webb said. (He later noted that they were able to go back at the end of August and install the station.)

At the northern end of the Chihuahuan desert, Bosque del Apache National Wildlife Refuge is a major destination for migrating and wintering waterfowl as well as for birders. Webb was seeking to determine if the four grassland birds he’s studying—thick-billed longspurs, chestnut-colored longspurs, Baird’s sparrows, and Sprague’s pipits—are using the refuge during the winter, during migration, or both.

Those four species are small songbirds with ochre, tan, or black plumage that make them well-camouflaged in shortgrass prairie habitat. The birds are difficult to capture for tagging without large vegetation to conceal the researchers’ mist nets, Webb said.

Even so, Webb said the payoff is great: “There’s really never been a technology that works well enough to be able to collect this data” for such tiny birds, he said. And after a bird is tagged with its transmitter “backpack,” it doesn’t need to be recaptured.

Migrating shorebirds are another group of Western birds with steep population losses in recent decades. Julián Garcia Walther, a Mexican biologist and Ph.D. student at the University of Massachusetts, Amherst, is monitoring shorebirds in northwest Mexico to find out more about climate change impacts on sea level rise and biodiversity. “I started thinking about how these birds that live on the interface between land and sea, the intertidal zone, how they’re going to be affected by sea level rise,” Garcia Walther said.

He learned about Motus in 2019, and realized the small tags used in the network were ideal for monitoring red knots, many of which winter in the coastal wetlands of northwest Mexico and whose populations are under pressure. But there were no Motus stations in the region.

Garcia Walther has now installed about 25 Motus stations with the help of the Mexican conservation organization Pronatura Noroeste, where he is the Motus network coordinator, along with other partner organizations. “It’s a big learning curve,” he said, requiring skills in electricity, radio communications, and construction. One of his biggest challenges is sourcing materials in Mexico, so he turned to improvised materials, like a pole once used for an osprey nest converted into an antenna mast.

Another hurdle was capturing the birds. Without tagged birds, stations are “just poles and antennas,” Garcia Walther said. Shorebirds are especially tricky to capture because they disperse across the coastline’s open expanses. While the harness method used for tagging grassland birds is also often used in shorebird research, Garcia Walther added, his team uses glue to secure the tags to the backs of red knots, meaning the birds will shed the devices when they molt.

But with three years of data from some 100 birds, Garcia’s team has made some significant observations. One finding, the result of data from Motus stations as well as GPS loggers—trackers that show fine-scale movements—revealed that during high spring tides, red knots use dried seagrass as rafts to rest on while the tidelands are inundated.

“This is analogous to what’s going to happen with sea-level rise,” Garcia Walther said. The data he has collected should help wildlife researchers plan for the future when there will likely be little shoreline available for roosting, he said, informing strategies to protect, restore, and improve vulnerable habitats.

Garcia Walther said he got advice from colleagues in the U.S. when he was setting up his stations, and he now helps scientists elsewhere in Latin America with their Motus projects.

Blake Barbaree, a senior ecologist at Point Blue Conservation Science with projects in California’s Central Valley, also depends on cross-border collaboration. His team is investigating the impact of drought on shorebirds, using Motus to track the movements of birds in California during the winter as well as during migration.

Since they’re only in the second season, Barbaree said it’s too soon to draw any definitive conclusions, though data collected at Motus towers has confirmed high connectivity between the Central Valley and coastal Washington, as well as the Copper River Delta in Alaska. “Numerous detections at Motus stations along the coasts of Oregon and British Columbia,” he wrote in a follow-up email, “have also highlighted the fact that a network of stopover sites is critical to their migration.”

This linkage, Barbaree said, helps researchers “piece together puzzles of population increases or decreases,” looking for impacts not just in wintering or breeding grounds but in key stopover habitats.

The network “has really opened up a world of migratory connectivity research” on other small animals like insects and bats, Barbaree added. And he’s seen it inspire collaboration between researchers investigating not just birds, but other migratory species.

Motus projects include studies on bats and insects, for example, with more than 340 species tagged to date. And scientists are turning to Motus for help identifying threats common to birds and bats. In 2023, a team from the U.S. Geological Survey installed two coastal Motus stations in California—with plans to install about two dozen more—to monitor three seabird species and three species of bats, to determine potential impacts of offshore energy.

After a major effort last winter to tag grassland birds in northern Mexico, Webb followed their migration north in the spring—via data their tags uploaded to the Motus website. A Baird’s sparrow his team tagged was tracked from Chihuahua to northern Kansas and up through North Dakota and Montana, the first time they had connected migratory stops through North American grassland habitats in such detail. It was “a lot of fun this spring watching the stations every morning,” he said.

DeLuca of the Audubon Society said understanding the life cycles of different species is the first step in revealing the factors causing their decline, like habitat loss or pollution. “When you think of all of the drivers that are pushing these species” towards extinction, he said, “it’s really kind of mind boggling.”

And climate change, he said, is an additional “huge over-arching pressure,” since it affects bird migration directly with impacts like increased severe weather, and indirectly when food resources like fruit or insects aren’t available.

Identifying the habitats birds rely on during migration and winter is key, DeLuca said.

And the Motus network can amplify those efforts.

The Motus philosophy is “all about collaboration,” Garcia Walther said. In addition to recording birds tagged by his own team, his Motus stations in Mexico are detecting birds from other research projects.

Once a tower is installed, any bird tagged by a Motus collaborator anywhere in the world can be detected there. “Any stations we place benefit the network as a whole,” Webb noted. And most of the data collected is publicly accessible on the Motus website.

The more the network grows, DeLuca said, “the more flexibility we have in terms of the kinds of questions we can answer with Motus.”

And with increased knowledge, scientists can better target conservation actions.

“The more we know, the more we realize just how dire the situation is,” DeLuca said. For migratory birds, he said, “The stakes, honestly, could not be higher.”

Etsy creators, Poshmark sellers, and side hustlers in general are receiving a Thanksgiving pardon from the IRS and its latest guidelines pertaining to digital sales and payment platforms. The new, drastically lowered $600 threshold to receive a tax reporting form from third-party settlement organizations such as Venmo and PayPal is delayed yet again.

First announced as part of the Biden administration’s 2021 American Rescue Plan, the regulation previously scheduled for the 2023 tax season substantially reduced the Form 1099-K benchmark for third party commerce service providers. Previously, those forms were only issued to people with more than 200 transactions or $20,000 in total profits. The new rules would drop the requirement down to just $600 in profit. The majority of such commerce is facilitated by services like the aforementioned Venmo and PayPal, as well as Square and Zelle. Ensuing backlash from lawmakers, tax filing companies, and the public eventually caused the IRS to issue its first delay in December 2022.

On Tuesday, the IRS conceded the estimated 44 million pending Form 1099-K’s could result in unnecessary “potential confusion” this year for “many taxpayers who wouldn’t expect one and may not have a tax obligation.”

“We spent many months gathering feedback from third party groups and others, and it became increasingly clear we need additional time to effectively implement the new reporting requirements,” IRS Commissioner Danny Werfel said in Tuesday’s announcement. “It’s clear that an additional delay for tax year 2023 will avoid problems for taxpayers, tax professionals and others in this area.”

[Related: How to avoid tax season stress.]

The government’s newest pause comes alongside a more detailed, transitional plan before the $600 limit goes into effect in 2025. The 200 transaction, $20,000 profit margin will lower to $5,000 for tax year 2024, although the IRS did not specify the number of transactions in its November 21 statement. The originally intended $600 limit will finally move into place the following year. The IRS also revealed new plans to update and simplify the existing Form 1099-K “to make the reporting process easier.” Basically, you won’t receive an official tax form for upselling thrift store finds in your spare time until early 2026—and when you do, it should hypothetically be less of a headache.

Although all this really just boils down to delaying the inevitable, the US government is also forging ahead with ways to make tax filing both simpler, and potentially cheaper. The upcoming 2024 filing season will finally see the long-awaited IRS free federal direct tax filing pilot program for certain eligible citizens in 13 participating states. The no-cost option is intended to eventually become nationally available as an alternative to third-party filing services like Intuit TurboTax and H&R Block. Such companies have come under increasing regulatory scrutiny in recent years for allegedly predatory practices, deceptive advertising, and privacy concerns.

As for those of you with extremely lucrative side gigs—sorry, the $20,000 limit will remain in place for 2024. While third party services usually automatically generate forms for anyone exceeding the IRS 1099-K threshold, that’s not the case for everyone else. Meanwhile, the IRS also reminded the public that business income has always been taxable, and it’s still up to Americans to report such profits even if they don’t receive a Form 1099-K. Do with that information what you will.

Apart from their nasty stings, army ant colonies are often known for their stunning, intricate architectural feats using their own bodies. When worker ant hunting parties encounter obstacles such as fallen tree branches, gaps in foliage, or small streams, the tiny insects will join forces to create a bridge for the remaining ant brethren to traverse. It’s as impressive as it is somewhat disconcerting—these are living, crawling buildings, after all. But one research team isn’t studying the coordination between miniscule bugs to benefit future construction projects; they are looking into how army ant teamwork could be mimicked by robots.

“Army ants create structures using decentralized collective intelligence processes,” Isabella Muratore, a postdoctoral researcher at the New Jersey Institute of Technology specializing in army ant building techniques, explains to PopSci over email. “This means that each ant follows a set of rules about how to behave based on sensory input and this leads to the creation of architectural forms without the need for any prior planning or commands from a leader.”

[Related: These robots reached a team consensus like a swarm of bees.]

Along with engineers from NJIT and Northwestern University, Muratore and her entomologist colleagues developed a series of tests meant to gauge army ant workers’ reactions and logistical responses to environmental impediments. After placing obstacles in the ants’ forest paths, Muratore filmed and later analyzed the herds’ subsequent adaptations to continue along their routes. Utilizing prior modeling work, the team also tested whether the ant bridges could withstand sudden, small changes in obstacle length using an adjustable spacing device.

Muratore and others recently presented their findings at this year’s annual Entomological Society of America conference. According to their observations, army ants generally choose to construct bridges in the most efficient locations—places wide enough to necessitate a building project while simultaneously using the least number of ants possible. The number of bridges needed during a sojourn also influences the ants’ collective decisions on resource allocation.

David Hu, a Georgia Institute of Technology engineering professor focused on fire ant raft constructions during flooding, recently likened the insects to neurons in one big, creepy-crawly brain while speaking to NPR on the subject. Instead of individual ants determining bridge dimensions and locations, each ant contributes to the decisions in their own small way.

[Related: Robot jellyfish swarms could soon help clean the oceans of plastic.]

Muratore and her collaborators believe an army ant’s collaborative capabilities could soon help engineers program swarms of robots based on the insect’s behavior principles and brains. Ants vary across species, but they still can pack a surprising amount of information within their roughly 1.1 microliter volume brains.

Replicating that brainpower requires relatively low energy costs. Scaling it across a multitude of robots could remain comparatively cheap, while exponentially increasing their functionality. This could allow them to “flexibly adapt to a variety of challenges, such as linking together to form bridges over gaps of different lengths in the most efficient manner possible,” Muratore writes to PopSci.
Robotic teamwork is crucial to implement the machines across a number of industries and scenarios, from outer space exploration, to ocean cleanup projects, to search-and-rescue efforts in areas too dangerous for humans to access. In these instances, coordinating quickly and efficiently not only saves time and energy, it could save lives.

Sam Altman is CEO of OpenAI once again. The return of the influential AI startup’s co-founder caps a chaotic four-days that saw two replacement CEOs, Altman’s potential transition to Microsoft, and threats of mass resignation from nearly all of the company’s employees. Altman’s return to OpenAI will coincide with a shakeup within the company’s nonprofit arm board of directors.

Silicon Valley’s pre-Thanksgiving saga started on November 17, when OpenAI’s board suddenly announced Altman’s departure after alleging the 38-year-old entrepreneur “was not consistently candid in his communications with the board, hindering its ability to exercise its responsibilities.”

The move shocked not only shocked industry insiders and investors, but executive-level employees at the company, as well. OpenAI’s president Greg Brockman announced his resignation less than three hours after news broke, while the startup’s chief operating officer described his surprise in a November 18 internal memo.

“We can say definitively that the board’s decision was not made in response to malfeasance or anything related to our financial, business, safety, or security/privacy practices,” he wrote at the time.

A flurry of breathless headlines ensued, naming first one, then another CEO replacement as rumors began circulating that Altman would join Microsoft as the CEO of its new AI development team. Microsoft previously invested over $13 billion, and relies on the company’s tech to power its growing suite of AI-integrated products.

Just after midnight on November 22, however, Altman posted to X his intention to return to OpenAI alongside a reorganized board of directors that will include previous members such former White House adviser and Harvard University President Larry Summers, as well as former Quora CEO and early Facebook employee Adam D’Angelo. This is just what happened. Entrepreneur Tasha McCauley, OpenAI chief scientist Ilya Sutskever, and director of strategy and foundational research grants at Georgetown University’s Center for Security and Emerging Technology Helen Toner are no longer board members.

“[E]verything i’ve [sic] done over the past few days has been in service of keep this team and its mission together,” Altman wrote on the social media platform owned by former OpenAI executive Elon Musk. Altman added he looks forward to returning and “building on our strong partnership” with Microsoft.

Although concrete explanations behind the attempted corporate coup remain unconfirmed, it appears members of the previous board believed Altman was “pushing too far, too fast” in their overall goal to create a safe artificial general intelligence (AGI), a term referring to AI that is comparable to, or exceeds, human capacities. Many of AI’s biggest players believe it is their ethical duty to steer the technology towards a future that benefits humanity instead of ending it. Critics have voiced multiple, repeated concerns over Silicon Valley’s approach, ethos, and rationality.

After three years of construction and limited operations, the next-generation Hyundai Motor Group Innovation Center production facility in Singapore is officially online and fully functioning. Announced on November 20, the 935,380-square-foot, seven-floor facility relies on 200 robots to handle over 60 percent of all “repetitive and laborious” responsibilities, allowing human employees to focus on “more creative and productive duties,” according to the company.

In a key departure from traditional conveyor-belt factories, HMGIC centers on what the South Korean vehicle manufacturer calls a “cell-based production system” alongside a “digital twin Meta-Factory.” Instead of siloed responsibilities for automated machinery and human workers, the two often cooperate using technology such as virtual and augmented reality. As Hyundai explains, while employees simulate production tasks in a digital space using VR/AR, for example, robots will physically move, inspect, and assemble various vehicle components.

[Related: Everything we love about Hyundai’s newest EV.]

By combining robotics, AI, and the Internet of Things, Hyundai believes the HMGIC can offer a “human-centric manufacturing innovation system,” Alpesh Patel, VP and Head of the factory’s Technology Innovation Group, said in Monday’s announcement. 

Atop the HMGIC building is an over 2000-feet-long vehicle test track, as well as a robotically assisted “Smart Farm” capable of growing up to nine different crops. While a car factory vegetable garden may sound somewhat odd, it actually compliments the Singapore government’s ongoing “30 by 30” initiative.

Due to the region’s rocky geology, Singapore can only utilize about one percent of its land for agriculture—an estimated 90 percent of all food in the area must be imported. Announced in 2022, Singapore’s 30 by 30 program aims to boost local self-sufficiency by increasing domestic yields to 30 percent of all consumables by the decade’s end using a combination of sustainable urban growth methods. According to Hyundai’s announcement, the HMGICS Smart Farm is meant to showcase farm productivity within compact settings—while also offering visitors some of its harvested crops. The rest of the produce will be donated to local communities, as well as featured on the menu at a new Smart Farm-to-table restaurant scheduled to open at the HMGICS in spring 2024.

HMGICS is expected to produce up to 30,000 electric vehicles annually, and currently focuses on the IONIQ 5, as well as its autonomous robotaxi variant. Beginning in 2024, the facility will also produce Hyundai’s IONIQ 6. If all goes according to plan, the HMGICS will be just one of multiple cell-based production system centers.

Rogue monster waves, once believed extremely rare, are now statistically confirmed to occur “all the time” thanks to researchers’ new, artificial intelligence-aided analysis. Using a combined hundreds of years’ worth of information gleaned from over 1 billion wave patterns, scientists collaborating between the University of Copenhagen and the University of Victoria have produced an algorithmic equation capable of predicting the “recipe” for extreme rogue waves. In doing so, the team appear to also upend beliefs about oceanic patterns dating back to the 1700’s.

Despite centuries of terrifying, unconfirmed rumors alongside landlubber skepticism, monstrous rogue waves were only scientifically documented for the first time in 1995. But since laser measuring equipment aboard the Norwegian oil platform Draupner captured unimpeachable evidence of an encounter with an 85-foot-high wall of water, researchers have worked to study the oceanic phenomenon’s physics, characteristics, and influences. Over the following decade, oceanographers came to define a rogue wave as being at least twice the height of a formation’s “significant wave height,” or the mean of the largest one-third of a wave pattern. They also began confidently citing “some reasons” behind the phenomena, but knew there was much more to learn.

[Related: New AI-based tsunami warning software could help save lives.]

Nearly two decades after Draupner, however, researchers’ new, AI-assisted approach offers unprecedented analysis through a study published today in Proceedings of the National Academy of Sciences.

“Basically, it is just very bad luck when one of these giant waves hits,” Dion Häfner, a research engineer and the paper’s first author, said in a November 20 announcement. “They are caused by a combination of many factors that, until now, have not been combined into a single risk estimate.”

Using readings obtained from buoys spread across 158 locations near US coasts and overseas territories, the team first amassed information equivalent to 700 years’ worth of sea state information, wave heights, water depths, and bathymetric data. After mapping all the causal variables that influence rogue waves, Häfner and their colleagues used various AI methods to synthesize the data into a model capable of calculating rogue wave formation probabilities. (These included symbolic regression which generates an equation output rather than a single prediction.) Unfortunately, the results are unlikely to ease fears of anyone suffering from thalassophobia.

“Our analysis demonstrates that abnormal waves occur all the time,” Johannes Gemmrich, the study’s second author, said in this week’s announcement. According to Gemmrich, the team registered 100,000 dataset instances fitting the bill for rogue waves.

“This is equivalent to around 1 monster wave occurring every day at any random location in the ocean,” Gemmrich added, while noting they weren’t necessarily all “monster waves of extreme size.” A small comfort, perhaps.

Until the new study, many experts believed the majority of rogue waves formed when two waves combined into a single, massive mountain of water. Based on the new equation, however, it appears the biggest influence is owed to “linear superposition.” First documented in the 1700’s, such situations occur when two wave systems cross paths and reinforce one another, instead of combining. This increases the likelihood of forming massive waves’ high crests and deep troughs. Although understood to exist for hundreds of years, the new dataset offers concrete support for the phenomenon and its effects on wave patterns.

And while it’s probably disconcerting to imagine an eight-story-tall wave occurring somewhere in the world every single day, the new algorithmic equation can at least help you stay well away from locations where rogue waves are most likely to occur at any given time. This won’t often come in handy for the average person, but for the estimated 50,000 cargo ships daily sailing across the world, integrating the equation into their forecasting tools could save lives.

Knowing this, Häfner’s team has already made their algorithm, research, and amassed data available as open source information, so that weather services and public agencies can start identifying—and avoiding—any rogue wave-prone areas.

The SUV market is big business, especially in the United States. Even supercar manufacturers like Lamborghini are making five-seat SUVs and thriving. Aston Martin’s DBX crossover represents roughly half of its overall sales. And that’s only on the gas-powered side. All-electric SUVs are just starting to find their groove, and vehicles like the three-row Kia EV9 SUV and Volkswagen ID.Buzz “microbus” are on their way to the U.S. market in 2024. Now, emerging luxury EV builder Lucid just announced the Gravity, a seven-seat SUV with an astonishing claim of 440 miles of all-electric range.

The SUV boasts other niceties like acceleration from zero to 60 miles per hour in less than 3.5 seconds, 1,500 pounds of payload (what it can carry inside) and the ability to tow 6,000 pounds. To compare, Tesla’s Model X can tow 5,000 pounds, haul 1,065 pounds inside the vehicle, and can go for 348 miles with the long-range package.

Here’s how Lucid is pushing other EV automakers to increase range and capability.

Gunning for Tesla

Lucid started producing its first model, the Air, in 2021 after more than a dozen years developing battery technology. Launched with 520 miles of EPA-estimated all-electric range and up to 1,111 horsepower, the Air earned rave reviews from users and journalists alike. Luxurious and uncommonly aerodynamic (more about that below), the Air’s starting price is roughly the same as a Tesla Model S. However, the Lucid model gets 115 more miles of range and  91 more horsepower than the Tesla.

If it sounds like an intrastate basketball rivalry, it may be partially attributed to the cross-pollination across the executive level. Before joining Lucid in 2013, CEO Peter Rawlinson spent three years at Tesla as a top engineer. Rawlinson led the engineering team for the Model S; when he left Tesla, he emerged swinging with the Lucid Air sedan. 

The company’s latest accomplishment is the Gravity SUV, and Lucid says “it can achieve 440 miles of range with a battery pack a little more than half the size of some of our battery-hungry competitors.” For context, a GMC Hummer EV’s battery pack alone weighs in at a hefty 2,818 pounds on the GM’s Ultium platform. 

The entire Lucid Air weighs 5,203 pounds and the Gravity is expected to tip the scales north of 6,000 pounds. Sure, it’s relatively heavier than some three-row SUVs such as the Kia Telluride and Lexus GX, but it’s on par with others like the Grand Wagoneer. 

Advanced battery technology 

Carrying two electric motors, the Gravity is touted as more efficient than its competitors. Rawlinson says the Gravity’s smaller and lighter technology battery pack means consuming fewer precious metals and minerals and results in less energy to charge and less pressure upon the grid. 

The Lucid Air is available with two battery packs–92 kilowatt hours or 112 kilowatt hours–and while Lucid is being vague about its exact specs for now, we expect the Gravity to utilize the larger 112 kWh version. For scale, the GMC Hummer EV and Cadillac Escalade IQ use packs over 200 kWh. 

Justin Berkowitz, Lucid’s senior manager for technology PR, says the company offers “the most efficient electric motors on the market and ultra-high voltage power electronics (over 900 volts compared to many EVs at 400-500).” All of these are designed, patented, engineered, and manufactured in-house by Lucid, and the company also develops the software powering it all. 

The stellar range is also a result of Lucid’s proprietary winding technique that produces a denser magnetic field along with several other innovations that create a super-compact package. The company holds eight patents related to the motor’s windings and cooling, and continues to find ways to squeeze as much copper into the motor stator as possible to generate big energy in a small package.

Aerodynamics are also a key, and Lucid says the Gravity has a drag coefficient of under 0.24. The lower the number, the more efficient the result. Hyundai’s three-row gas-powered Palisade has a 0.33 coefficient of drag, and the upcoming Kia EV9 hits 0.28. Tesla says its Model X sits at 0.24, so Lucid is sliding just below that with the Gravity. It’s still not as aerodynamic as the five-passenger Hyundai Ioniq 6, which has an impressive 0.21 drag coefficient. Give them time, though. Lucid is poised for major growth.

Cruise CEO Kyle Vogt announced his resignation from the controversial robotaxi startup on Sunday evening. The co-founder’s sudden departure arrives after months of public and political backlash relating to the autonomous vehicle fleet’s safety, and hints at future issues for the company purchased by General Motors in 2016 for over $1 billion.

Vogt’s resignation follows months of documented hazardous driving behaviors from Cruise’s autonomous vehicle fleet, including injuring pedestrians, delaying emergency responders, and failing to detect children. Cruise’s Golden State tenure itself lasted barely two months following a California Public Utilities Commission greenlight on 24/7 robotaxi services in August. Almost immediately, residents and city officials began documenting instances of apparent traffic pileups, blocked roadways, and seemingly reckless driving involving Cruise and Google-owned Waymo robotaxis. Meanwhile, Cruise representatives including Vogt aggressively campaigned against claims of an unsafe vehicle fleet.

[Related: San Francisco is pushing back against the rise of robotaxis.]

“Anything that we do differently than humans is being sensationalized,” Vogt told The Washington Post in September.

On October 2, a Cruise robotaxi failed to avoid hitting a woman pedestrian first struck by another car, subsequently dragging her 20 feet down the road. GM issued a San Francisco moratorium on Cruise operations three weeks later, followed by a nationwide expansion of the suspension on November 6.

But even with Cruise on an indefinite hiatus, competitors like Waymo and Zoox continue testing autonomous taxis across San Francisco, Los Angeles, Phoenix, Austin, and elsewhere to varying degrees of success. As The New York Times reports, Waymo’s integration into Phoenix continues to progress smoothly. Meanwhile, Austin accidents became so concerning that city officials felt the need to establish an internal task force over the summer to help log and process autonomous vehicle incidents.

[Related: Self-driving taxis allegedly blocked an ambulance and the patient died.]

In a thread posted to X over the weekend, Vogt called his experience helming Cruise “amazing,” and expressed gratitude to the company and its employees while telling them to “remember why this work matters.”

“The status quo on our roads sucks, but together we’ve proven there is something far better around the corner,” wrote Vogt before announcing his plans to spend time with his family and explore new ideas.

“Thanks for the great ride!” Vogt concluded.

Update November 22, 2023, 10:06am: Actually, nevermind, Sam Altman is back as OpenAI’s CEO.

OpenAI, the company behind ChatGPT, has had a wild weekend. On Friday, founder and CEO Sam Altman was fired by its board of directors, kickstarting an employee revolt that’s still ongoing. The company has now had three CEOs in as many days. The shocking shakeup at one of the most important companies driving artificial intelligence research could have far-reaching ramifications for how the technology continues to develop. For better or worse, OpenAI has always claimed to work for the good of humanity, not for profit—with the drama this weekend, a lot of AI researchers could end up at private companies, answerable only to shareholders and not society. Things are still changing fast, but here’s what we know so far, and how things might play out.

[ Related: A simple guide to the expansive world of artificial intelligence ]

‘Too far, too fast’

November should have been a great month for OpenAI. On November 6th, the company hosted its first developer conference where it unveiled GPT-4 Turbo, its latest large language model (LLM), and GPTs, customizable ChatGPT-based chatbots that can be trained to perform specific tasks. While OpenAI is best known for the text-based ChatGPT and DALL·E, the AI-powered image generator, the company’s ambitions include the development of artificial general intelligence, in which a computer matches or exceeds human capabilities. The industry is still currently debating the broad definition of AGI and OpenAI plays a large role in that conversation. This tumult has the potential to resonate well beyond the company’s own hierarchy.  

[ Related: What happens if AI grows smarter than humans? The answer worries scientists. ]

The recent upheaval stems from OpenAI’s complicated corporate structure, which was intended to ensure that OpenAI developed artificial intelligence that “benefits all of humanity,” rather than allowing the desire for profitability to enable technology that could potentially harm us. The AI venture started as a non-profit in 2015, but later spun out a for-profit company in 2019 so it could take on outside investment, including a huge deal with Microsoft. The quirk is that the board of directors of the non-profit still has complete control over the for-profit company and they are all barred from having a financial interest in OpenAI. 

However, the six-member board of directors had unchecked power to remove Altman—which it exercised late last week, to the surprise of almost everyone including major investors. Microsoft CEO, Satya Nadella, was reportedly “blindsided” and “furious” at how Altman was fired, as were many of OpenAI’s staff who took to Twitter/X to post heart emoji in support of Altman.

Initially, the board claimed that Altman was let go because “he was not consistently candid in his communications,” however, later accounts site differing opinions on the speed and safety of how OpenAI’s research was being commercialized. According to The Information, Ilya Sutskever, the company’s chief scientist and a board member, told an emergency all-hands meeting, “This was the board doing its duty to the mission of the nonprofit, which is to make sure that OpenAI builds [artificial general intelligence] that benefits all of humanity.” Sutskever apparently felt that Altman was “pushing too far, too fast,” and convinced the board to fire him, with chief technology officer Mira Murati taking over as the interim CEO. According to The Atlantic, the issues stemmed from the pace at which ChatGPT was deployed over the past year. The chatbot initially served as a “low-key research preview,” but it exploded in popularity and with that, features have rolled out faster than the more cautious board members were comfortable with. 

As well as Altman, President of the board Greg Brockman resigned in protest, which really kicked off the chaotic weekend. 

Three CEOs in three days and the threat of an exodus

Following internal pushback from the employees, over the weekend, Altman was reportedly in talks to resume his role as CEO. The extended will-they-won’t-they eventually fizzled. To make things more dramatic, Murati was then replaced as CEO by Emmett Shear, co-founder of streaming site Twitch, bringing the company to three CEOs in three days. Shear reportedly believes that AI has somewhere between a five percent and 50 percent chance of wiping out human life, and has advocated for slowing down the pace of its development, which aligns with the boards’ reported views.

Of course, as one of the biggest names in AI, Altman landed on his feet—both he and Brockman have already joined Microsoft, one of OpenAI’s biggest partners. On Twitter/X late last night, Microsoft CEO Satya Nadella, announced that he was “extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team.”

This morning, more than 500 of OpenAI’s 750 employees signed an open letter demanding that the board step down and Altman be reinstated as CEO. If they don’t, Microsoft has apparently assured them that there are positions available for every OpenAI employee. Shockingly, even Sutskever signed the letter and also posted on Twitter/X that he regretted his “participation in the board’s actions.”

Turbulent aftermath

As of now, things are still developing. Unless something radical shifts at OpenAI, it seems like Microsoft has pulled off an impressive coup. Not only does the company continue to have access to OpenAI’s research and development, but it suddenly has its own advanced AI research unit. If the OpenAI employees do walk, Microsoft will have essentially partially acquired the $86 billion company for free.

Whatever happens, we’ve just seen a dramatic shift in the AI industry. For all the chaos of the last few days, the non-profit OpenAI was founded with laudable goals and the board seems to have seriously felt that their role was to ensure that AI—particularly, artificial general intelligence or AGI—was developed safely. With an AI advocate like Altman now working for a for-profit company unrestrained by any such lofty charter, who’s to say that it will? 

Similarly, OpenAI’s credibility is in serious doubt. Whatever its charter says, if the majority of the employees want to plow ahead with AGI development, it has a major problem on its hands. Either the board is going to have to fire a lot more people (or let them walk over to Microsoft) and totally remake itself, or it’s going to cave to the pressure and change its trajectory. And even if Altman does somehow rejoin OpenAI, which looks less and less likely, it’s hard to imagine how the non-profit’s total control of the for-profit company stays in-place. Somehow, the trajectory of AI seems considerably less predictable than it was just a week ago.

Update November 20, 2023, 2:11pm: Shear, OpenAI’s current CEO, has said he will launch an independent investigation into the circumstances around Altman’s firing. While it might be too little, too late for some employees, he says the investigation will allow him to “drive changes in the organization” up to and including “signification governance changes.”

Update November 21, 2023, 2:30pm: In an interview with CNN Monday evening, Microsoft CEO Satya Nadella reiterated the possibility that Altman could still return to his previous role at OpenAI. Nadella added he was “open to both possibilities” of Altman working for either OpenAI, or Microsoft.

SpaceX’s second, unpiloted Starship test flight of the year ended in yet another fiery inferno on November 18. This time, the sudden end arrived roughly 8 minutes into its 90-minute scheduled mission. But although its Super Heavy first stage booster suffered a fatal “rapid unscheduled disassembly” in the Caribbean, the world’s most powerful rocket almost doubled its previous lifespan and passed multiple other crucial milestones.

Starship launched once again from its test site near Boca Chica, Texas, at 8:03am ET on Saturday, with all 39 of the Super Heavy booster’s Raptor engines remaining lit during the mission—a first for the spacecraft intended to eventually deliver humans to Mars. At two minutes and 41 seconds following liftoff, Starship’s hot-staging sequence—in which upper stage engines ignite and separate from the booster—also proceeded successfully, clearing yet another hurdle for SpaceX engineers. The reusable booster then performed its flip maneuver en route towards an intended safe return back to Earth, but exploded only a few seconds later. The booster’s fate wasn’t a huge surprise, however, as SpaceX mission control operators already suspected such a dramatic event could occur due to the immense “load on top of the booster.”

Meanwhile, the Starship upper stage continued to soar for another few minutes to roughly 92 miles above the Earth’s surface—well above the Kármán Line, an internationally recognized demarcation between the planet’s atmosphere and outer space. Moments before its scheduled Second Engine Cut Off, or SECO, the upper stage met its own explosive demise. Space X representatives cited a delay in Starship’s automated flight termination system, but do not yet know the exact cause for its malfunction. If successful, Starship would have circumnavigated Earth before performing a hard landing near Hawaii.

The results of April’s Starship test received considerable criticism from both Boca Chica locals and the Federal Aviation Administration for surrounding environmental damage sustained during launch. Starship’s Raptor engines burn approximately 40,000 pounds of fuel per second to reach 17 million pounds of thrust. Nearby Texan residents described the blowback as resembling a “mini earthquake” at the time, with at least one business owner’s store window shattering. The April 20 test flight blasted a 25-feet deep crater, ejecting clouds of dirt, dust, and debris into the air while smashing a bowling ball-sized fragment into a nearby NASA Spaceflight van. Much of the area near Starship’s launch site includes protected ecosystems, as well as land considered sacred by local Indigenous communities. The FAA soon issued 63 corrective actions needed before SpaceX could legally attempt another Starship test.

[Related: SpaceX’s Starship launch caused a ‘mini earthquake’ and left a giant mess.]

Unlike SpaceX’s outing, Starship’s upgraded launch mount reportedly better mitigated the resulting blowback—at least according to Elon Musk’s company assessment. The FAA, meanwhile, wasted no time in issuing its own statement on Saturday’s event.

“A mishap occurred during the [SpaceX] Starship OFT-2 launch from Boca Chica, Texas, on Saturday, Nov. 18,” the administration posted to X over the weekend. Although no injuries or public property damage was reported this time, the FAA promised to oversee the “SpaceX-led mishap investigation” to ensure the company will comply with “regulatory requirements.”

Although NASA’s Psyche spacecraft is currently en route to its rendezvous with a unique, metal-heavy asteroid floating between Mars and Jupiter, it still has quite a while before it reaches its destination. But researchers aren’t waiting until the end of its 3.5 year, 280-million-mile journey to make the most of the project. Even after barely a month of spaceflight, Psyche is already achieving some impressive technological feats.

On November 16, NASA announced its Deep Space Optical Communications experiment aboard Psyche successfully achieved “first light” earlier this week, beaming a data-laden, near-infrared laser nearly 10 million miles back to Caltech’s Palomar Observatory. Additionally, DSOC operators were able to “close the link”—the vital process in which test data is simultaneously beamed through both uplink and downlink lasers. Although only the first of numerous test runs to come, it completes a necessary step within NASA’s ongoing plans to develop far more powerful communications tools for future space travel.

[Related: In its visit to Psyche, NASA hopes to glimpse the center of the Earth.]

Astronauts, ground crews, and private companies have all utilized radio wave frequencies for data transfers and communications since the late-1950’s, thanks to a global antenna array known as the Deep Space Network. As organizations like NASA aim to expand humanity’s presence beyond Earth in the coming decades, they’ll need to move away from radio systems to alternatives like infrared lasers. Not only are such lasers more cost efficient, but they are also capable of storing and transmitting far more information within their shorter wavelengths. Further along in DSOC’s development, for example, will hopefully accomplish data transmission rates between 10-to-100 times greater than today’s spacecraft radio systems.

“Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity’s next giant leap: sending humans to Mars,”  Trudy Kortes, NASA’s director of Technology Demonstrations, said in Thursday’s announcement.

NASA also noted that, while similar infrared communications has been successfully achieved in low Earth orbit as well as to-and-from the moon, this week’s DSOC milestone marks the first test through deep space. This is more difficult thanks to the comparatively vast, growing distance between Earth and Psyche. During the November 14 test, data took roughly 50 seconds to travel from the spacecraft to researchers in California. At its farthest distance from home, Psyche’s data-encoded photons will take around 20 minutes to relay. That’s more than enough time for both Earth and Psyche to drift further along their own respective cosmic paths, so laser arrays on the craft and at NASA will need to adjust for the changes. Future testing will ensure the terrestrial and deep space tech is up to the task.

[Related: NASA’s mission to a weird metal asteroid has blasted off.]

Once it becomes the new norm, Jason Mitchell, director of the Advanced Communications and Navigation Technologies Division within NASA’s Space Communications and Navigation (SCaN) program, believes optical lasers will offer a “boon” for researchers’ space missions data collection, and will help enable future deep space exploration.
“More data means more discoveries,” Mitchell said in NASA’s announcement.

A litany of issues has plagued Formula One’s highly anticipated (and derided) Las Vegas Grand Prix race for months, but the event’s most recent issues are perhaps its most ridiculous yet—the cars on-average 212 mph speeds are too fast for the Vegas Strip.

F1 racers can’t bolt down any standard roadway—they require specialized, carefully laid pavement. America’s other two F1 venues in Austin, Texas, and Miami, Florida, were both built specifically for the high-speed races, but the Las Vegas Grand Prix circuit presents a wholly different challenge, as it is located within the city itself. To prepare for this weekend’s competition, workers first removed the route’s top 5-to-10 inches of asphalt before replacing it with 60,000 tons of a base layer followed by another 43,000 tons of intermediate and top layer pavement.

Speaking to The Washington Post on Thursday, Las Vegas Convention and Visitors Authority chief executive Steve Hill estimated the new circuit pavement would last 6-10 years, and only need piecemeal maintenance without requiring extensive road closures.

But according to event organizers on November 16, F1 drivers’ first, late evening practice run barely lasted eight minutes before abruptly being forced to end. Near the track’s final corner, racer Carlos Sainz suddenly stopped, reporting apparent damage to his Ferrari’s flooring. A quick investigation of the track revealed that the race car’s speed and accompanying force put too much stress on a drain cover’s concrete framing, causing it to protrude and significantly damage the Ferrari’s chassis—the main frame to which its engine and suspension are attached. If that weren’t enough, racer Esteban Ocon’s car received a similar blow from the dislodged debris shortly after Sainz.

[Related: How the Formula races plan to power their cars with more sustainable fuel.]

This isn’t the first time grates proved to be an F1 car’s Achilles heel—another vehicle suffered a similar fate at a practice during the 2019 Azerbaijan Grand Prix. In that instance, however, F1 organizers welded shut the track’s coverings—a solution unavailable to last night’s crew members since it’s illegal to do so under Nevada law. Instead, repairers raced (so to speak) down the Las Vegas track, applying quick-setting concrete to the remaining 20-to-30 coverings.

It was 2:30am local time before racers could return for a second practice run. By this point, they raced past attendee stands devoid of any fans. Labor laws prevented security workers from continuing to staff the event. Those who attempted to stick it out to see the racers return were forced to leave for the night around 1:3gett0am. The competitors completed their trial runs without further incident.

Both drivers and their team members haven’t minced words since the evening’s debacle. Belgian and Dutch racer Max Verstappen described the Vegas Grand Prix as “99 percent show and 1 percent sport,” while Ferrari boss Fred Vasseur called the incident “unacceptable.”

“The situation is we damaged completely the monocoque, the engine, the batteries. I’m not sure this is the topic for me today,” Vasseur told reporters at the time. “We had a very tough [first practice], it cost us a fortune, we fucked up the session for Carlos.”

Mercedes chief Toto Wolff, however, defended the race and described the issue as a “black eye,” but nothing else. “This is nothing… they’re going to seal the drain covers and nobody’s going to talk about that tomorrow morning anymore,” Wolff continued.

Car seats, like the vehicles themselves, are available in a variety of materials with a wide range of manual and electronic controls. My old 1977 Dodge Aspen, for instance, had a front row bench seat that moved as one, like a faux-brocade couch on rails. It had no ventilation, no heat, and definitely no massaging functions. Automobile seating has come a long way since then. 

The first production car with optional heated seats was the 1966 Cadillac DeVille, and massaging seats came along decades later in 2000 Mercedes-Benz and Cadillac models. Bentley, however, has taken the spa-like cabin to the next level with its available “airline seat specification” setup; the British brand says its super-deluxe airline seat specification is a world first.

This $11,000 option in the extended wheelbase version (EWB) of the Bentayga includes not just heat, but cooling, massage, recline, and small trays that fold out like those on a commercial airline. This SUV’s seats even have sensors that predict that you’re about to start sweating even before you know it yourself and preemptively adjusts the temperature. 

Here’s how they work.

First class seats

When travelers on an airplane upgrade to business or first class, they gain a significant amount of legroom and space around their seat. Bentley chose to call this Bentayga EWB setup “airline seat specification” to drive home the message that this is a roomy, first-class experience. As soon as you sit down, the sheer number of positioning options is dizzying: The rear seats can be adjusted 22 ways, not including the rear footrest behind the front passenger seat. 

Steve James, the head of interior design for Bentley, has been developing seating for the luxury brand since 2006. His first task when he joined Bentley was to come up with the initial concept for the seats in Bentley’s then-new flagship model, the Mulsanne. While the uber-luxurious Mulsanne model included heated, cooled, and massaging seats, the Bentayga EWB says “hold my Dom Perignon” and ratchets it up even more to prevent fatigue, not just treat it.   

“High-end cars focus quite a lot on fatigue recovery; if you’re getting tired in the car, the massage function is designed to help after the fact,” James says. “But we thought the real luxury experience is to do something to stop the fatigue in the first place. We saw an opportunity with the Bentayga EWB because we have more room to work with.” 

Science, research, and “perfect posture” 

James explains that Bentley focused on two key metrics during the development of the first-class seats: posture and thermal response. Bentley collaborated with an American chiropractor and Comfort Motion Global (CMG), a company that partners with research universities to test its proprietary technologies. Through its research, it discovered that making small adjustments in the leg and back angles of a vehicle seat–as little as one to two degrees–results in a positive increase of blood flow, increasing alertness and reducing fatigue. 

Bentley’s seats are fitted with 12 electric motors and three pneumatic valve engine control units. Unique algorithms developed in conjunction with CMG apply 177 individual pressure changes, shifting stress points from one area to another to stop the onset of fatigue. And the leg rest feature in the Bentayga is situated at a particular angle to create what James calls “perfect posture” that bends the legs slightly for maximum comfort and blood flow. 

“As you may have experienced if you’re in a plane or sitting statically for a long period of time, fatigue sets in,” James says. “The postural system is a system of pneumatic bladders inside the seat and they make small micro-adjustments that fine-tune the angles of your pelvis, your thighs, they are helping motion constantly happen. Small motions that give the customer the option to regulate them. They really make a difference.”

Temperature

Another important element of Bentley’s high-end seats is what it calls “thermal comfort.” (There is a default calibration, but it can be adjusted depending on the average temperature preference of the passenger.)

Bentley embedded two sensors in the seats, each constantly measuring humidity and temperature levels of the bottoms and backs of the seats. With that data, the car can automatically activate its seat climate system for heating or ventilation to maintain the passenger’s individual comfort level. James says that the system detects temperature variations of 0.1 degrees and registers upward and downward trends and the human brain doesn’t notice before the delta is 0.5. So the seats’ constant monitoring heads off perspiration before it even happens.

While the concept started to take shape in 2015, the brand didn’t create a working prototype until 2019 after years of data collection and validation. The team had to do quite a bit of calibration on the thermal comfort side, as different passengers feel comfort at vastly different temperatures depending on a number of factors. And as it turned out, one of the engineers became a real-time case study; he became ill during the development and started feeling hot and sweaty. As designed, the system measured that and calculated the delta in his calibration preferences. 

“The real clever bit of the system is it can sense even to one-tenth of a degree Celsius at all times,” James says. “It can measure how you’re feeling and how your temperature is trending. So if you start feeling a little bit warm or perspire a bit–we can actually see it before you feel it.”

In a mainstream car with heated seats, you might find that activating them to full power feels wonderful in cold temperatures until you start overheating. At that point, the seats hold residual warmth that feels uncomfortable until it cools off. Bentley’s seats are designed for an ideal balance of hot and cool so that you feel consistently content.

Hindsight is not quite 20/20 for NASA’s historic Apollo missions. For instance, the Apollo 12 lander successfully touched down on the moon at exactly 6:35:25 UTC on November 19, 1969. What happened to the lunar environment as astronauts touched down, however, wasn’t recorded—and exact details on the reactions between nearby rocks, debris, and lunar regolith to lander engines’ supersonic bursts of gas aren’t documented. And physically replicating Apollo 12’s historic moment on Earth isn’t possible, given stark differences in lunar gravity and geology, not to mention the moon’s complete lack of atmosphere.

This is particularly a problem for NASA as it continues to plan for astronauts’ potential 2025 return to Earth’s satellite during the Artemis program. The landing craft delivering humans onto the lunar surface will be much more powerful than its Apollo predecessors, so planning for the literal and figurative impact is an absolute necessity. To do so, NASA researchers at the Marshall Space Flight Center in Huntsville, Alabama, are relying on the agency’s Pleiades supercomputer to help simulate previous lunar landings—specifically, the unaccounted information from Apollo 12.

As detailed by NASA earlier this week, a team of computer engineers and fluid dynamics experts recently designed a program capable of accurately recreating Apollo 12’s plume-surface interactions (PSI), the interplay between landing jets and lunar topography. According to the agency, the Pleiades supercomputer generated terabytes of data over the course of several weeks’ worth of simulations that will help predict PSI scenarios for NASA’s Human Landing System, Commercial Lunar Payload Services, and even future potential Mars landers.

[Related: Meet the first 4 astronauts of the ‘Artemis Generation’]

NASA recently showed off one of these simulations—the Apollo 12 landing—during its appearance at SC23, an annual international supercomputing conference in Denver, Colorado. For the roughly half-minute simulation clip, the team relied on a simulation tool called the Gas Granular Flow Solver (GGFS). The program is both capable of modeling interactions to predict regolith cratering, as well as dust clouds kicked up around the lander’s immediate surroundings.

According to the project’s conference description, GGFS utilizing its highest fidelities can “model microscopic regolith particle interactions with a particle size/shape distribution that statistically replicates actual regolith.” To run most effectively on “today’s computing resources,” however, the simulation considers just one-to-three potential particle sizes and shapes.

The approximation of the final half-minute of descent before engine cut-off notably includes depictions of shear stress, or the lateral forces affecting a surface area’s erosion levels. In the clip, low shear stress is represented by a dark purple hue, while the higher shear stress areas are shown in yellow.

Going forward, the team intends to optimize the tool’s source code, alongside integrating increased computational resources. Such upgrades will allow for better, higher fidelity simulations to fine-tune Artemis landing procedures, as well as potentially plan for landing missions far beyond the lunar surface.

• Dimensions: 4.45 x 2.6 x 1.28 inches

Pros

• Waterproof
• Extremely tough
• Versatile lens
• Underwater shooting modes
• Compatible with tons of accessories

Cons

• Small sensor

This point-and-shoot camera can go pretty much anywhere. It’s waterproof down to 50 feet without a separate case. It’s totally dust-proof, so it won’t suffer if you take it to the beach or deep in the desert. Plus, it’s crush-proof up to 220 pounds, so you can sit on it by accident and still go shooting later in the day. Most compacts can’t stand up to that kind of abuse. 

Toughness isn’t worth much if the camera isn’t very good. This compact offers a relatively small sensor, but it has a versatile 4x zoom lens that will cover most common scenarios on your adventures. And if you fall in love with the camera, Olympus offers a ton of different accessories like action camera mounts and underwater lights to go with it. (Looking for something cheaper but still waterproof? We’ve got you.)

Best film camera: Ilford Sprite 35-II Reusable 35mm Film Camera

SEE IT

Specs

• Sensor: N/A
• Lens: f/9 31mm
• Weight: 4 ounces
• Dimensions: 4.7 x 2.6 x 1.7 inches

Pros

• Comes in eight fun color combinations
• Very affordable
• Fixed settings make it easy to use
• Features a built-in flash

Cons

• Fixed settings may be limiting
• Plastic lens results in some softness

If you want to get your feet wet with film, the Ilford Sprite 35-II is a fantastic and fun choice. It’s similar to disposable camera in that it has a plastic lens with a fixed aperture and shutter speed. But it’s reloadable, thus producing less waste. And it simply looks cooler than a disposable camera as well.

The Sprite 35-II features a 31mm lens with a fixed f/9 aperture to ensure that your scene is in focus. It also has a fixed 1/120s shutter speed. There is a built-in flash for low-light situations, perfect for shooting indoors. You won’t get precisely sharp and perfect results from this camera, but we think that’s half the fun. It’s a great outlet compared to highly technical cameras and fun to bring along on outings with friends and family. And since it has no settings at all, it’s a true point-and-shoot that is extremely simple to use, even with it being a film camera.

Best instant camera: Instax Mini 11

SEE IT

Specs

• Sensor: N/A
• Lens: f/12.7 60mm
• Weight: 10.34 ounces
• Dimensions: 4.24 x 4.77 x 2.65 inches

Pros

• Affordable
• Produces fun, tiny instant prints
• Easy to use
• Includes a selfie mirror on the lens

Cons

• Results aren’t the sharpest

There’s just something special about a camera spitting out an image, and the wait for it to appear seemingly magically. The best instant cameras are easy to use and result in attractive prints, which is true of the Instax Mini 11. The results aren’t pristine like you may be used to with your phone or digital camera, but we think that’s part of the charm.

The Instax Mini 11 features a fixed 60mm lens with an f/12.7 aperture that focuses from 11.8 inches to infinity. Or, you can turn the lens to Selfie Mode for a close focusing range of 11.8 to 19.7 inches. And there is a built-in flash, which is ideal for indoor shooting. It is a little slick to hold but comes with a lanyard to prevent drips.

I recently let my nieces and nephews—all under 12—use the Instax Mini 11, and seeing how excited they were was a blast. They all wanted to keep taking photos despite the limited quantity of film I had and ran around showing the rest of the family what they captured. And despite some of them being quite young (and impatient to take a photo), they all managed to take a clear and relatively sharp photo. 

Best for street photography: Ricoh GR IIIx

SEE IT

Specs

• Sensor: 24.2MP APS-C CMOS sensor
• Lens: f/2.8 26.1mm (35mm equivalent: 40mm)
• Weight: 9.2 ounces
• Dimensions: 4.3 x 2.4 x 1.4 inches

Pros

• Large sensor provides excellent image quality
• Compact and pocket-friendly
• 40mm lens is sharp and versatile

Cons

• No zoom
• Battery life isn’t great

Ricoh’s GR IIIx is a fantastic pick for street photography, largely thanks to its compact design. It is pocketable, so you can easily keep it on you when out and about. And it won’t draw much attention when you take it out to snap a photo. It also has slick all-black styling and an easy-to-hold design, even when shooting with one hand.

This discreet look is furthered by the lack of a zoom lens. It uses a fixed 40mm focal length (35mm equivalent), so you won’t lose the compact size when taking photos. 40mm is also an ideal focal length for street photography, as it is wide enough to get some context in the scene but not so wide that you end up with loads of extra space around your subject. If you do want something wider, the GR III is essentially the same, except it features a wider 28mm equivalent lens.

The GR IIIx image quality is excellent, partly thanks to the relatively large sensor. Images are sharp all the way to the edges, even when shooting wide open at f/2.8. And it produces vibrant, attractive colors. Interested in learning more? Check out our full review of the GR IIIx on Popular Photography.

Sony’s ZV-1 is a camera truly designed for vloggers and, as a result, is packed with features to make recording yourself easier. The auto exposure settings keep your face bright and clear. It even centers your face and quickly adjusts background blur with the push of a Background Defocus button. And the little camera gets Sony’s impressive autofocus abilities, so if you are showcasing other people or products, the camera will quickly find focus for you.

The forward-directional onboard mic and detachable windscreen will help you get great sound, leaving you fussing with levels in post less. There’s also a handy flip screen so you can preview the frame and capture the perfect shots and angles, making it one of the best point-and-shoot cameras for vlogging.

• Weight: 1.35 pounds
• Dimensions: 5.1 x 3.7 x 4.7 inches

Pros

• Massive zoom range
• Responsive autofocus
• 4K30p video recording
• Easy to hold

Cons

• Not as compact as other options

Panasonic’s Lumix DC-FZ80 is an affordable bridge camera, offering a DSLR-like body with easy-to-use controls. Because of the deep hand grip, it’s an easy camera to hold than the other point-and-shoots mentioned on our list. It isn’t as compact as a result, so it is a tradeoff, but for many, the classic feel is preferred. 

The built-in lens provides a whopping 60x zoom, making it suitable for just about any situation you find yourself wanting to photograph. And it’s autofocus is quite responsive, so you’ll be more likely to get sharp photos as well. And it’s capable of 4K video, making it a good tool for getting started with video as well. And best of all? It’s cheaper than most alternatives.

Things to consider when shopping for the best point-and-shoot cameras

Point-and-shoot cameras are small and compact cameras that can create sharp, vibrant images. This makes them the best camera for beginners, a good option for travelers, and even a worthy choice for some professional uses. Here are some features to consider when choosing the right one for you.

Are you a true beginner?

A point-and-shoot camera is designed to make the process of photography as simple as possible. They typically feature fully automatic exposure and focus so that you can, as the name implies, point the camera and snap a photo with nothing more than a press of a button. If you are a true beginner and want the easiest-to-use camera, you’ll want to look for models with simple menu systems and fully automatic controls. 

That said, some point-and-shoots offer more settings than others. If you are slightly beyond beginner status or want a camera to grow into, check to see what settings the camera allows you to change. You may want to adjust things like ISO, shutter speed, and aperture down the line, as opposed to relying on auto exposure modes.

Will you travel with your camera?

One of the main purposes of a compact camera is that the camera is, well, compact. With typical dimensions of roughly 2.5 x 3.5 x 1.5 inches, point-and-shoots are specifically designed to easily fit into pockets, purses, fanny packs, and other small compartments. And unlike hefty DSLRs or mirrorless cameras, point-and-shoot cameras weigh way less than a single pound. And if you’re worried about safety, the discreet size of compact cameras makes them less of a target for theft.

While all point-and-shoot cameras are pretty compact, there are still size differences across available cameras. Be sure to pay attention to the dimensions and weight of the cameras you are considering if that is something important to you.

Do you need a tough camera for an active lifestyle?

If you live for the outdoors—hiking steep mountain trails or backpacking through desert Canyons—you need a point-and-shoot camera that can handle adventure. Rugged and waterproof cameras are built to endure and capture the extreme environments you love exploring. Taking electronics to the beach is usually a big no-no, as even a single grain of sand can cause damage. Yet rugged models can resist sand, allowing you to take all the sunset shots you want.

For us less risky folk, these tough cameras can survive your average accidental drops, spills, and kicks. Some of them may be overkill for general use, however. If you don’t intend to take your camera on rugged adventures, you may be able to save some money by getting a camera without extensive protective qualities.

The common stethoscope’s recognizable design has remained largely unchanged for decades for good reason—there’s really not much to improve at this point. When it comes to listening in on a patient’s internal soundtrack, the standard, adjustable bell connected via short rubber tubing to binaural earpieces is perfectly suited for helping assess respiratory and cardiac health.

Of course, a stethoscope can only relay vitals in person based on its specific placements; long term monitoring often requires extended clinical stays alongside bulky, wired devices. To solve these problems, a team of medical experts, researchers, and engineers at Northwestern University set out to design a new wearable capable of providing highly detailed, continuous, real-time information regardless of a patient’s environment. After painlessly adhering to specific areas of the chest, the resulting soft devices not only accomplish these goals, but already show immense promise for both adults, as well as premature babies often dealing with gastrointestinal complications and apneas.

[Related: Pill cuts lung cancer deaths in half, study says.]

“Currently, there are no existing methods for continuously monitoring and spatially mapping body sounds at home or in hospital settings,” John Rogers, a bioelectronics expert who oversaw the new tool’s design and development, said in a recent Northwestern University profile.

As detailed in a new study published in Nature Medicine, Rogers and fellow researchers placed a miniature battery, electronics, Bluetooth relay, flash memory drive, and two microphones within a 40mm long, 20mm wide, and 8 mm thick soft silicone casing—roughly the size of a stick of gum. Each microphone is positioned in opposing directions, into and outside the patient, to filter exterior ambient noises from a wearer’s bodily sounds. The team notes this is particularly helpful in situations such as lung monitoring, since the organ is simply too quiet when compared to noisy hospital surroundings.

Ankit Bharat, a thoracic surgeon who oversaw adult subject clinical device trials, describes it pretty succinctly in Northwestern’s November 16 announcement:

“Simply put, it’s like up to 13 highly trained doctors listening to different regions of the lungs simultaneously with their stethoscopes, and their minds are synced to create a continuous and a dynamic assessment of the lung health that is translated into a movie on a real-life computer screen.”

[Related: Almost everyone in the world breathes unhealthy air.]

Aside from adult lung and gastrointestinal health monitoring, the tiny wearables show incredible promise for infants—particularly those born with potential medical issues. Babies’ respiratory systems only fully mature during the third trimester of pregnancy, meaning many apnea and breathing disorders often accompany premature deliveries. Given these infants’ physical size, traditional stethoscopes are both impractical and too large to provide accurate, prolonged monitoring. And even for healthy delivered children, breathing and gastrointestinal issues are major concerns during their first five years. The team’s new wearables, however, account for these issues by providing a new, size-appropriate tool.

Every human body is host to a wide array of acoustic and tonal signatures. Once the particular sounds are documented, the team hopes their wearable will make it much easier to pick out irregularities stemming from serious, overlooked health issues. If detected early enough, such discoveries could potentially save countless lives.

New research from Oxford University and the University of Adelaide found that asbestos exposure has led to a higher incidence of asbestos-related lung cancers in British and Australian naval personnel. The study published November 14 in the journal Scientific Reports estimates that the proportion of lung cancers related to onboard asbestos exposure was 27 percent in Australian naval personnel and 12 percent in British servicemembers.

[Related: The US never banned asbestos. These workers are paying the price.]

Toxic exposure

This study is a reminder of the continuing need for protections against exposure to harmful airborne dusts and other dangerous substances from sources like toxic burn pits. According to the United States Department of Veterans Affairs, nearly 300,000 United States veterans have reported exposure to pollution from burn pits since the early 2000s. The chemical pollutants that were released during these burns include volatile organic compounds associated with cancer, kidney disease, and nervous system damage. In August 2022, President Joe Biden signed the PACT Act into law to address the health concerns related to burn pits like these.

Illnesses related to asbestos exposure persist, despite the mineral being a known carcinogen. Asbestos has been used in a wide variety of building materials for their strength, flexibility, and electrical and heat resistant properties. Breathing it in can cause mesothelioma, lung cancer, and a non-cancerous condition called asbestosis. About 1,290 Americans die annually from asbestos-related causes, according to the Centers for Disease Control and Prevention (CDC).

Australia currently has a ban and strict control on asbestos-containing materials, they still pose a risk to some workers. A 2021-2022 New South Wales Dust Disease Register report found that there were 142 cases of asbestosis and 111 deaths related to the illness. 

In the United States, asbestos use is not completely banned. The Environmental Protection Agency (EPA) proposed another ban in April of 2022 that has yet to be finalized. 

An increased risk to sailors

For this study, researchers collected data from 30,085 United Kingdom and Australian personnel who served during the 1950s and 1960s. During this time period, asbestos-containing materials were still present in British and Australian naval vessels. Earlier studies of one Australian and two British cohorts also involved in this new research found that increased rates of lung cancer could not be attributed to radiation exposure from nuclear testing. The team used a separate study of Australian Korean War veterans as a comparison in this new research.

The team found that all four cohorts had an elevated incidence of mesothelioma among naval veterans. This same rate was not not statistically significant among sailors from the Korean War. British and Australian personnel involved in nuclear testing also saw higher rates of lung cancers.

Additionally, the rates of pulmonary disease and heart disease were similar between naval and army personnel. This suggests that smoking was not driving higher lung cancer rates among sailors.

“We found the lung cancer rate was higher overall in naval personnel than in the other armed services, and, while smoking remains the dominant cause of lung cancer, it is unlikely the excess could be explained by a higher smoking rate in the navy,” study co-author and University of Adelaide medical doctor Richard Gun said in a statement.  “Although actual measurements of airborne asbestos levels were not available, and estimates are difficult, we have concluded that the higher lung cancer rate in sailors was most probably caused by onboard asbestos exposure.”

The high occurrence of deaths in sailors from asbestosis also strengthened the team’s conclusion. The team believes that the effects of asbestos exposure are likely underestimated, unless lung cancer is considered alongside mesothelioma and asbestosis.

“Although it remains true that smoking causes most lung cancers, other agents such as asbestos can contribute to the incidence of cancer in an exposed population,” Gun said. “Moreover, we know from other studies that the combination of smoking and asbestos exposure has an enhanced influence on lung cancer risk; this interactive effect would have contributed to the observed lung cancer excess.”

To call soft robotic hands “complex” is a bit of an understatement. These designs consider a number of engineering factors, including the elasticity and durability of materials. This usually entails separate 3D-printing processes for each component, often with multiple plastics and polymers. Now, however, engineers working together from ETH Zurich and the MIT spin-off company, Inkbit, can create extremely intricate products with a 3D-printer utilizing a laser scanner and feedback learning. The researchers’ impressive results already include a six-legged gripper robot, an artificial “heart” pump, sturdy metamaterials, as well as an articulating soft robotic hand complete with artificial tendons, ligaments, and bones.

Traditional 3D-printers use fast-curing polyacrylate plastics. In this process, UV lamps quickly harden a malleable plastic gel as it is layered via the printer nozzle, while a scraping tool removes surface imperfections along the way. While effective, the rapid solidification can limit a product’s form, function, and flexibility. But trying to swap out the fast-curing plastic for slow-curing polymers like epoxies and thiolenes mucks up the machinery, meaning many soft robotic components require separate manufacturing methods.

Knowing this, designers wondered if adding scanning technology alongside rapid printing adjustments could solve the slow-curing hurdle. As detailed in their new paper published in Nature, their new system not only offers a solution, but demonstrates 3D-printed, slow-curing polymers’ potential across a number of designs.

Instead of scraping away imperfections layer-by-layer, three-dimensional scanning offers near-instantaneous information on surface irregularities. This data is sent to the printer’s feedback mechanism, which then adjusts the necessary material amount “in real time and with pinpoint accuracy,” Wojciech Matusik, an electrical engineering and computer science professor at MIT and study co-author, said in a recent project profile from ETH Zurich.

To demonstrate their new method’s potential, researchers created a quartet of diverse 3D-printed projects using soft-curing polymers—a resilient metamaterial cube, a heart-like fluid pump capable of transporting “liquids” through its system, a six-legged robot topped with a sensor-informed two-pronged gripper, as well an articulating hand capable of grasping objects using embedded sensor pads.
While refinements to production methods, polymers’ chemical compositions, and lifespan are still needed, the team believes the comparatively fast and adaptable 3D-printing method could one day lead to a host of novel industrial, architectural, and robotic designs. Soft robots, for example, offer less risk of injury when working alongside humans, and can handle fragile goods better than their standard, metal robot counterparts. Already, however, the existing advances have produced designs once impossible for 3D printers.

As technology evolves, AI-generated images of human faces are becoming increasingly indistinguishable from real photos. But our ability to separate the real from the artificial may come down to personal biases—both our own, as well as that of AI’s underlying algorithms.

According to a new study recently published in the journal Psychological Science, certain humans may misidentify AI-generated white faces as real more often than they can accurately identify actual photos of caucasians. More specifically, it’s white people who can’t distinguish between real and AI-generated white faces. 

[Related: Tom Hanks says his deepfake is hawking dental insurance.]

In a series of trials conducted by researchers collaborating across universities in Australia, the Netherlands, and the UK, 124 white adults were tasked with classifying a series of faces as artificial or real, then rating their confidence for each decision on a 100-point scale. The team decided to match white participants with caucasian image examples in an attempt to mitigate potential own-race recognition bias—the tendency for racial and cultural populations to more poorly remember unfamiliar faces from different demographics.

“Remarkably, white AI faces can convincingly pass as more real than human faces—and people do not realize they are being fooled,” researchers write in their paper.

This was by no slim margin, either. Participants mistakenly classified a full 66 percent of AI images as photographed humans, versus barely half as many of the real photos. Meanwhile, the same white participants’ ability to discern real from artificial people of color was roughly 50-50. In a second experiment, 610 participants rated the same images using 14 attributes contributing to what made them look human, without knowing some photos were fake. Of those attributes, the faces’ proportionality, familiarity, memorability, and the perception of lifelike eyes ranked highest for test subjects.

The team dubbed this newly identified tendency to overly misattribute artificially generated faces—specifically, white faces—as “AI hyperrealism.” The stark statistical differences are believed to stem from well-documented algorithmic biases within AI development. AI systems are trained on far more white subjects than POC, leading to a greater ability to both generate convincing white faces, as well as accurately identify them using facial recognition techniques.

This disparity’s ramifications can ripple through countless scientific, social, and psychological situations—from identity theft, to racial profiling, to basic privacy concerns.

[Related: AI plagiarism detectors falsely flag non-native English speakers.]

“Our results explain why AI hyperrealism occurs and show that not all AI faces appear equally realistic, with implications for proliferating social bias and for public misidentification of AI,” the team writes in their paper, adding that the AI hyperrealism phenomenon “implies there must be some visual differences between AI and human faces, which people misinterpret.”

It’s worth noting the new study’s test pool was both small and extremely limited, so more research is undoubtedly necessary to further understand the extent and effects of such biases. But it remains true that very little is still known about what AI hyperrealism might mean for populations, as well as how they affect judgment in day-to-day lives. In the meantime, humans may receive some help in discernment from an extremely ironic source: During trials, the research team also built a machine learning program tasked with separating real from fake human faces—which it proceeded to accurately accomplish 94 percent of the time.

No one can entirely predict where the artificial intelligence industry is taking everyone, but at least the AI is poised to reliably tell you what the weather will be like when you get there. (Relatively.) According to a paper published on November 14 in Science, a new, AI-powered 10-day climate forecasting program called GraphCast is already outperforming existing prediction tools nearly every time. The open-source technology is even showing promise for identifying and charting potentially dangerous weather events—all while using a fraction of the “gold standard” system’s computing power.

“Weather prediction is one of the oldest and most challenging–scientific endeavors,” GraphCast team member Remi Lam said in a statement on Tuesday. “Medium range predictions are important to support key decision-making across sectors, from renewable energy to event logistics, but are difficult to do accurately and efficiently.”

[Related: Listen to ‘Now and Then’ by The Beatles, a ‘new’ song recorded using AI.]

Developed by Lam and colleagues at Google DeepMind, the tech company’s AI research division, GraphCast is trained on decades of historic weather information alongside roughly 40 years of satellite, weather station, and radar reanalysis. This stands in sharp contrast to what are known as numerical weather prediction (NWP) models, which traditionally utilize massive amounts of data concerning thermodynamics, fluid dynamics, and other atmospheric sciences. All that data requires intense computing power, which itself requires intense, costly energy to crunch all those numbers. On top of all that, NWPs are slow—taking hours for hundreds of machines within a supercomputer to produce their 10-day forecasts.

GraphCast, meanwhile, offers highly accurate, medium range climatic predictions in less than a minute, all through just one of Google’s AI-powered machine learning tensor processing unit (TPU) machines.

During a comprehensive performance evaluation against the industry-standard NWP system—the High-Resolution Forecast (HRES)—GraphCast proved more accurate in over 90 percent of tests. When limiting the scope to only the Earth’s troposphere, the lowest portion of the atmosphere home to most noticeable weather events, GraphCast beat HRES in an astounding 99.7 percent of test variables. The Google DeepMind team was particularly impressed by the new program’s ability to spot dangerous weather events without receiving any training to look for them. By uploading a hurricane tracking algorithm and implementing it within GraphCast’s existing parameters, the AI-powered program was immediately able to more accurately identify and predict the storms’ path.

In September, GraphCast made its public debut through the organization behind HRES, the European Center for Medium-Range Weather Forecasts (ECMWF). During that time, GraphCast accurately predicted Hurricane Lee’s trajectory nine days ahead of its Nova Scotia landfall. Existing forecast programs proved not only less accurate, but also only determined Lee’s Nova Scotia destination six days in advance.

[Related: Atlantic hurricanes are getting stronger faster than they did 40 years ago.]

“Pioneering the use of AI in weather forecasting will benefit billions of people in their everyday lives,” Lam wrote on Tuesday, who notes GraphCast’s potential vital importance amid increasingly devastating events stemming from climate collapse.

“[P]redicting extreme temperatures is of growing importance in our warming world,” Lam continued. “GraphCast can characterize when the heat is set to rise above the historical top temperatures for any given location on Earth. This is particularly useful in anticipating heat waves, disruptive and dangerous events that are becoming increasingly common.”

Google DeepMind’s GraphCast is already available via its open-source coding, and ECMWF plans to continue experimenting with integrating the AI-powered system into its future forecasting efforts.

There are millions of pieces of space junk orbiting Earth these days, so what’s one more bit of detritus amidst the trash cloud?

According to NASA’s recent spacewalk debriefing, International Space Station denizens Jasmin Moghbeli and Loral O’Hara spent nearly seven hours conducting various repairs on a sun-tracking solar panel array. During their shift, however, one of their “crew lock bags” (astronaut-speak for a toolkit) accidentally got loose, and drifted away before either astronaut could catch it. While not a major issue in and of itself, this certainly highlights (yet again) the growing problem floating above humanity’s heads.

[Related: The FCC just dished out their first space junk fine.]

Thankfully, the lock bag didn’t contain anything of major importance. In a separate press conference last week, ISS deputy program manager Dana Weigel stated the bag’s contents included “some tethers and things like tool sockets” similar to the everyday household varieties, calling them “fairly common items” that aren’t a “huge impact” for the crew. Most importantly, Mission Control observed the bag’s current orbital trajectory and determined it presents a low risk of “recontacting” with the ISS, with “no action required.”

Meganne Christian, a European Space Agency 2022 astronaut class member, shared a clip on social media taken from Moghbeli’s helmet camera showing the toolbag’s escape into the cosmic abyss.

Since the toolbag isn’t in a stable orbit, experts estimate it will decay into Earth’s atmosphere sometime during March 2024. Given its size, the lost equipment will burn up completely during the descent, so there’s no need to stress or keep an eye to the sky—unless that’s your thing, of course.

The US Space Force already cataloged the new orbital debris as 58229/1998-067WC, and will track its movements over the course of its lifespan. Per The Register, the toolbag’s brightness is measured at a stellar magnitude +6, meaning you could hypothetically witness its atmospheric reentry with the naked eye during perfect weather conditions. That said, binoculars will probably increase the odds of seeing its fiery end.

[Related: Some space junk just got smacked by more space junk, complicating cleanup.]

But one toolbag’s atmospheric cremation does very little to solve the ongoing issue of space junk. After years of orbital industry expansion, the planet is surrounded by discarded rocket debris, satellites, and all manner of space travel detritus. It’s getting so bad that a recent project space junk cleanup project was suddenly complicated by its target colliding with another bit of trash.

Thankfully, governmental regulators are taking notice—earlier this year, the FCC issued its first ever space pollution fine to the satellite television provider, Dish Network, for failing to properly decommission one of its satellites last year. No penalties are expected for ISS astronauts Moghbeli and O’Hara; after all, they aren’t the first astronauts to drop the bag, so to speak. In 2008, two ISS astronauts accidentally lost a kit containing “two grease guns, scrapers, several wipes and tethers and some tool caddies.”

Update 11/17/2023 12:20PM : The Virtual Telescope Project has released this image, taken on November 15, 2023. The tool bag is still zooming around the Earth at roughly 17,500 mph until its projected March 2024 deorbit.

You only realize WiFi is not as ubiquitous as you thought it was when your boss wants to hop on a last-minute video call and the coffee shop you’re at has no guest network. That’s when you’d better know how to use your phone as a hotspot.

That type of urgent scenario is not the best moment to figure out how to connect your laptop or tablet to your mobile network, so you might as well learn now. That way, the next time you find yourself in a tricky situation, you’ll be ready to hop online. 

A quick note: some mobile plans do not support hotspotting, so even though your phone has the ability to share data, nothing will happen unless your mobile service provider allows it. So before you start trying to tether your device, confirm that your plan has a dedicated hotspot quota or that you are allowed to use your phone’s data on another device. 

How to use an iPhone as a hotspot

On iOS, you’ll find the hotspot menu by opening the Settings app, and tapping Personal Hotspot. If you’re using an older version of iOS, you may need to go to Settings > Cellular > Personal Hotspot. Enabling it is as easy as toggling on the switch next to Allow others to join, but don’t do that yet unless you know you’re alone.

[Related: The best mobile hotspots of 2023]

You don’t want just anybody to piggyback on your data plan, so make sure you set up a secure password before you create a hotspot. From the Personal Hotspot menu, tap Wi-Fi password and type in a safe one—think a semi-long combination of letters (upper- and lowercase), numbers, and special characters. 

Now that your hotspot is ready to go, choose how you want to connect. Apple’s mobile devices provide some options.

2. On your laptop or tablet (or whatever other device you want to use your mobile data), open the WiFi settings and search for a signal. 

You can do this on a Mac by clicking the WiFi icon in the top right corner of your screen. Your system will automatically detect nearby networks and list them for you. If you don’t see the name of your iPhone (that’s the name of your hotspot), click Other networks. 

On a PC, open the System Tray by clicking the three icons to the left of the clock in the bottom right corner of your screen. Make sure the WiFi icon is blue (that means it’s on), then click the arrow next to it to open your computer’s WiFi settings—you’ll see a list of the available networks containing your iPhone’s name. 

3. Regardless of the make of your device, once you find your iPhone on the list of WiFi networks, select it, type in the hotspot password, and you’ll be all set.

How to use your Android as a hotspot

Before you hook any device up to your Android phone’s mobile data, you’ll need to set up your personal hotspot. Swipe down with two fingers from the top of your screen to open the Quick Settings menu, then tap the cog icon in the bottom right corner of the screen to open Settings. Go to Network & internet, then Hotspot & tethering. 

Here you’ll find a toggle switch for every way to connect a device to your hotspot: Wi-Fi hotspot, Bluetooth tethering, USB tethering, and Ethernet tethering. The last two options will be blurred out unless your phone is already connected to a device via a USB or Ethernet cable. WiFi will likely be the easiest, but if you’re interested in trying something else, you can skip to the sections on USB tethering and Bluetooth tethering below.

Connect to your Android hotspot using WiFi

1. Tap Wi-Fi hotspot to set it up. Start by giving your hotspot a name—by default, it’ll be the name of your device, but you can change it to anything you want. 

Next, set up a Hotspot password to secure your connection and prevent strangers from draining your data plan. Make sure to choose a good one—a semi-long series of letters (upper- and lowercase), numbers, and special characters. 

You have two other options you can set up. Toggle on the switch next to Turn off hotspot automatically, and your Android phone will disable the feature whenever there are no devices connected to it. You can also tap the switch next to Extend compatibility, so your phone makes more of an effort to be discoverable to other devices. This will use up more battery power, so make sure to turn it off if you’re running out of juice. 

Once you’re done setting up your personal hotspot, hit the toggle switch next to Use Wi-Fi hotspot to turn it on. 

2. On your laptop or tablet (or whatever device you want to connect to your hotspot), open 

the WiFi settings. 

On a Mac, click the WiFi icon in the top right corner of your screen. Your system will find nearby networks automatically and list them for you. If you don’t see the name you gave your hotspot, click Other networks. 

If you’re using a PC, click the three icons to the left of the clock in the bottom right corner of your screen to open the System Tray panel. Make sure the WiFi icon is on (it should be blue), and open your computer’s WiFi settings by clicking the arrow next to it. There, you’ll see a list of available networks containing your hotspot’s name. 

Use your phone as a hotspot over a USB cable

You can connect your tablet or laptop to your phone’s hotspot via a USB cable, but it’s a lot easier with an Android. When it works, though, the connection between your phone and hotspot-using device is smooth as silk. 

Connect to your iPhone hotspot through a USB cable

There’s a catch here: You may only be able to easily do this between Apple products, so you might not be able to share your iPhone’s data with your PC or Chromebook, for example. 

1. On your iPhone, make sure your hotspot is active (from the Personal Hotspot menu, toggle on the switch next to Allow others to join) and connect your phone to your Mac using a USB cable. 

2. An alert will appear on your Mac—click Trust this device. You should see your iPhone appear as a drive on your computer’s Finder and you should be able to go online. 

If you’re not connected, go to your Mac’s System Settings and Network. You should see iPhone USB on the list of services—open it, click Make inactive, then Make active, and you should be good to go.

If you don’t see iPhone USB on the list, you’ll need to set it up as a new network. Scroll down all the way, click the three-dots dropdown menu, and choose Add service. Then follow Apple’s instructions to finish the setup.

Connect to your Android hotspot using a USB cable

Tethering your Mac or PC to your Android phone is surprisingly easy, and the connection is seamless. 

1. Connect your Android phone to your Mac or PC with a USB cable.

2. Go to the Hotspot & tethering menu (Settings > Network & internet > Hotspot & tethering) and toggle the switch next to USB tethering. The option will only be available if there’s a cable connecting your phone to another device. 

3. On a PC, Windows will offer to set up the connection between your phone and laptop, but you’ll realize you don’t have to do anything—as soon as you turn on the USB hotspot, your computer will connect to the internet. 

Something similar happens on a Mac—when you connect your phone, macOS will ask if you trust it. Click Trust this device and you should automatically have an internet connection. If you don’t, go to Settings and Network, and under Other services find your phone’s name. Open the item and click the button Make Inactive, which will change to Make active. Click it again and you should be good to go. 

How to create a phone hotspot with Bluetooth

You can share your phone’s cellular data with another device over Bluetooth, but connectivity tends to be slower and more finicky than WiFi- or USB-driven hotspots. In fact, we had so much trouble getting this to work that it might only be useful as a last resort.

Connect to your iPhone hotspot using Bluetooth

For this, you’ll need to pair your phone to whatever device you want to connect to the internet—how you do that will depend on your device. 

1. On your iPhone, make sure your hotspot is on (from the Personal Hotspot menu, toggle on the switch next to Allow others to join).

2. If you’re connecting your Mac to your hotspot, go to System Settings and on the left sidebar go to Bluetooth. If you’ve ever connected your iPhone to your Mac via Bluetooth, you’ll see your phone’s name under My devices—just hover the mouse over its name and click on the Connect button that appears. If you’ve never connected your gadgets, you should find your phone’s name under Nearby devices—you may have to scroll down a bit to see it. Hover the mouse over your phone’s name, click Connect, and follow the instructions on screen. 

If you’re trying to tether your iPhone to a PC, open the System Tray by clicking on the three icons to the left of the clock in the bottom right corner of your screen. Make sure the Bluetooth icon is blue (that means it’s on) and click the arrow next to it to open your computer’s Bluetooth settings. If you’ve connected your iPhone to your PC in the past, you should find your phone’s name under Your devices, but if you haven’t, you’ll find it under New devices. Either way, just click on it and follow the instructions on screen to establish a connection. 

Once the devices are paired, you’ll need to connect to the internet on your laptop. It’s very different depending on the make of your computer, and it’s definitely not as intuitive as hopping on a WiFi network.  

On a Mac, click the Control Center icon (two toggle switches) in the upper right corner of your screen. From the emerging menu, click Bluetooth to see a list of connected devices. Find your phone and hover the mouse over it—click Connect to Network when the option appears. 

On a PC, open Settings and go to Network & Internet. Scroll all the way down and under Related settings, pick More network adapter options. On the emerging window, you should see an item called Bluetooth Network Connection—open it, find your phone, and right-click on it. On the menu, hover over Connect using and choose Access point to connect to the web.

Connect to your Android hotspot using Bluetooth

If your devices play nice with each other over Bluetooth, you can use your mobile data plan with your laptop. Just keep in mind that some Android phones, like the Pixel 7, may have trouble connecting to a Mac computer. If that’s the case for you, we suggest you save yourself some grief by choosing the easier WiFi approach. 

1. Make sure your laptop is discoverable through Bluetooth. On a Mac, open the Control Center and ensure the Bluetooth icon is blue—if it’s not, click it to turn it on. On a PC, open the System Tray by clicking the icons to the left of the clock (bottom right corner of your screen) and make sure the Bluetooth icon is blue. If it’s not, click it to enable it.

2. On your phone, swipe down with one finger from the top of your phone screen to open the notification drawer, and on the tiles at the top of your screen, long-press on Bluetooth.

3. If you’ve tethered your phone and laptop before, find your laptop’s name under Saved devices, tap the cog icon next to it, and choose Connect on the next screen. If you’ve never paired your gadgets, choose Pair new device. Wait until your laptop appears in the list of discoverable nearby devices, and select it to start the pairing process. You’ll see prompts with five-digit codes on both screens—make sure they match and confirm the pairing. 

[Related: How to find free WiFi when you really need it]

Once the devices are paired, you’ll need to connect to the internet on your laptop. This will work differently depending on the make of your computer, and it won’t be as intuitive as hopping on a WiFi network.  

On a Mac, open the Control Center by clicking its icon (two sliders) in the upper right corner of your computer screen. On the emerging menu, click Bluetooth to see a list of connected devices. Find your phone and hover the mouse over it—click Connect to Network when the option appears. 

On a PC, open Settings and go to Network & Internet. Scroll all the way down and under Related settings, pick More network adapter options. On the emerging window, you should see an item called Bluetooth Network Connection—double-click to open it, find your phone, and right-click on it. On the menu, hover over Connect using and choose Access point.

Whether you use your iPad Pro recreationally or as a PC replacement, connecting a keyboard to Apple’s tablet can improve its utility and ease of use. You’ve been able to use a keyboard with the iPad since the original model was released in 2010, but in recent years, they’ve gained the ability to be controlled with a trackpad. Apple brought the gestures it developed for its laptops over to the tablet, which can help you navigate the iPad’s interface more quickly and work in professional apps more efficiently. To help you sort through it all, we’ve done the legwork (well, we’ve let our fingers do the walking) to find the best iPad Pro keyboards for everybody’s needs.

How we chose the best iPad Pro keyboards

We’re very familiar with iPad keyboards (really keyboards in general), so we’re very familiar with the main reasons you might pick one up. Writers and creatives will have more aggressive needs than folks who just want an easier way to dash off emails or prefer keyboard typing to tapping on a screen. We also ensured that our case recommendations were available in different sizes for both the 11- and 12.9-inch iPad Pro models. We were also mindful of having recommendations at every price point since some keyboards can get expensive.

The best iPad Pro keyboards: Reviews & Recommendations

Whether you’re ready to jump from using a traditional computer to an iPad Pro or want to breathe some new life into an older one that’s been underused, we’ve rounded up the best keyboards for your needs.

Best overall: Logitech Combo

SEE IT

Specs

• Keyboard Style: Folio keyboard case
• Connection: Apple Smart Connector
• Trackpad: Multitouch trackpad
• Power: Smart connector draws power from iPad

Pros

• Low profile prevents wrist fatigue
• Solid construction
• Great trackpad performance

Cons

• Price

If you’re looking for performance similar to the Apple Magic Keyboard but at a lower price point, the Logitech Combo is a perfect fit. 

The Logitech Combo connects to your iPad Pro via the Apple Smart Connector, similar to the Magic Keyboard, to give seamless connectivity and power. This makes attaching, packing, and using the Logitech Combo a breeze. We never had to worry about whether our iPad Pro’s Bluetooth settings were enabled; we just attached the keyboard and started typing.

Logitech makes some of our favorite tech accessories, and the quality of its iPad Pro keyboard case is no exception. The keys had a satisfying amount of travel, never failed to register when we pressed down, and were spaced apart perfectly. If you’ve typed on a MacBook Pro, you’ll feel right at home using the Logitech Combo. Similarly impressive was its trackpad, which was immediately responsive each time we swiped, clicked and dragged, or used a multi-finger gesture to move between apps.

The back of the Logitech Combo has a kickstand, which allows you to prop your iPad Pro up and even allows you to change the viewing angle for the greatest comfort. In practice, this made it a lot easier to use the Logitech Combo on our lap, a table, or desk. If you find yourself typing on the seat tray of an airplane seat, you’ll want the ability to switch positions if the person in front of you leans back. Apple Pencil owners will appreciate the cut-out on top of this case, which allows you to attach the stylus to the iPad Pro while it’s attached.

The Logitech Combo offers more protection than the Magic Keyboard, thanks to a case that wraps around the iPad’s edges. And when you are traveling, the keyboard covers the screen. If you want to use your iPad without the keyboard, though, you can detach it from the folio case and get the same edge protection without the keyboard in your way.

Overall, the Logitech Combo has the same performance as Apple’s own iPad Pro keyboard, with additional design elements that help it stay one step ahead.

Best splurge: Apple Magic Keyboard for iPad

Specs

• Keyboard Style: Folio keyboard case
• Connection: Apple smart connector
• Trackpad: Multitouch trackpad
• Power: Smart connector draws power from iPad

Pros

• Quiet keyboard switches
• Good keyboard feel
• Solid construction

Cons

• Price

The Apple Magic Keyboard for iPad Pro is the flagship model of iPad keyboard cases. As such, it has the fit and finish you’d expect from a first-party accessory. The keyboard’s build quality and key comfort are undeniable, but they come at the cost of a high price tag. 

The keyboard connects to your iPad Pro via the Apple Smart Connector, allowing it to draw power from your iPad, so you don’t have to charge the keyboard separately. The downside to this approach is that it will impact your tablet’s battery life. The iPad Pro has more than enough juice to last eight or nine hours of normal use (aka not playing games) even when the keyboard is attached.

This keyboard case covers the back of the iPad but doesn’t cover the sides, so if protection is a big concern, you might want something more robust. The bottom is rubberized, though, so that it will stay in place, and the handsome “floating cantilever” design allows you to adjust your viewing angle and feels great to move. The magnets that attach this keyboard case to the iPad Pro are strong enough to keep them together during everyday use without making detachment too hard when you want to use the tablet solo.

Typing and swiping on the Apple Magic Keyboard was a delight, eerily similar to the experience of using a MacBook Pro. If you’re comfortable typing on an Apple laptop, you’ll find no issues with the Magic Keyboard’s layout. Our only complaints—besides this keyboard’s high price—are its slightly too-small trackpad and the lack of function keys, which are generally used to adjust system settings like volume and screen brightness. We found ourselves reaching for the iPad Pro’s screen, which meant taking our fingers off the keyboard more often than we’d have liked.

The feel of the keyboard and touchpad are satisfying and will make you pleased to use Apple Magic Keyboard for iPad day after day for work or relaxation. 

Best rugged: Zagg Pro Keys

SEE IT

Specs

• Keyboard Style: Folio keyboard case
• Connection: Bluetooth
• Trackpad: Yes
• Power: USB-C rechargeable battery

Pros

• Solid protection with keyboard flexibility
• Backlit keys
• Easy pairing

Cons

• Bulkier than some options

Zagg’s Pro Keys is a durable iPad Pro keyboard with helpful features more expensive options don’t have.

The first thing we noticed after connecting this keyboard case to our iPad Pro was its size and weight. It’s a bit wider and heavier than other folio keyboard cases we recommend, but it gives our iPad robust full-edge protection. Zagg says you can drop it from a height of 6.6 feet (taller than the height of many tables) without the risk of damage. This extra bulk does make a noticeable difference when carrying an iPad Pro around—especially the larger model—but it’s a tradeoff worth making if you’re clumsy. This is especially true because Apple charges hundreds of dollars to repair a cracked display, depending on the model.

Many iPad Pro keyboards recommend using Apple’s proprietary smart connector, but the Zagg Pro Keys connects to the tablet over Bluetooth. We had no trouble pairing the accessory to our tablet, which we did by holding the function key and hitting the “1” key. The iPad Pro recognized this keyboard immediately and automatically paired to it thereafter. You can pair this keyboard with a second device by holding the function button and hitting the “2” key, which is helpful if you live in a multi-iPad household.

Typing on this keyboard case was pleasant thanks to the quiet-sounding keys, which require a tiny bit more force to depress than other models we tested. Their shape and size are also slightly different, which requires us to acquaint ourselves with its layout over a day or so. Once our hands made the slight adjustments, we had no more issues. For a bit of fun, the keyboard keys are backlit with seven different colors that you can cycle through for whatever color matches your energy. This keyboard case has two viewing angles you can switch between to keep you comfortable, and we appreciate the flexibility.

If an iPad Pro has become your primary computer, the Zagg Pro Keys will extend its usability and keep it safe.

Specs

• Keyboard Style: Folio keyboard case
• Connection: Bluetooth
• Trackpad: Yes
• Power: Rechargeable battery

Pros

• Truly laptop-like
• Excellent build quality
• Many viewing angles

Cons

• Heavy

If you’d like to turn your iPad Pro into a MacBook, Brydge’s 12.9 Pro+ Wireless Keyboard is the ideal accessory. The keyboard is made from aluminum, has the same keyboard layout as Apple’s laptops, and feels luxe right out of the box. The Pro+ Wireless Keyboard connects the iPad Pro over Bluetooth, and it paired instantly in our tests.

You attach this case to your iPad by slotting it into two clips on top of the keyboard. Once connected, you can tilt the keyboard forward and backward with pinpoint precision. If you’ve put off getting an iPad keyboard because of the lack of flexibility, this keyboard design solves that issue.

Overall, we found the keys and trackpad on Byrdge’s keyboard to be very responsive. Every key press was registered, and we very rarely had a dropped character. Our experience with this keyboard’s trackpad was similar; we felt the power of having total control over the iPad Pro’s cursor. Movements, swipes, and scrolling all felt smooth. Brydge released software updates through its iPadOS app to continually improve performance as Apple has updated its operating system.

What sets the Brydge 12.9 Pro+ Wireless Keyboard apart is just how MacBook-like the iPad Pro feels when it’s attached. Its aluminum chassis adds extra weight and thickness, which is noticeable when carrying the iPad around both on its own or in a bag. The iPad Pro’s relatively thin and light design is curtailed—but you can detach the iPad at any time. If you’d like your iPad Pro to look and feel like a next-generation MacBook, Byrdge’s 12.9 Pro+ Wireless Keyboard is the best choice.

Best budget: Logitech K380

SEE IT

Specs

• Keyboard Style: External Keyboard
• Connection: Bluetooth
• Trackpad: No
• Power: 2x AAA batteries

Pros

• Variety of colors
• Small and easy to travel with 
• Affordable

Cons 

• Keys are a bit small
• Have to replace batteries 

Unlike other entries in this article, the Logitech K380 is a proper external wireless keyboard rather than a keyboard case. Because of this, you get a lot of versatility from not having your keyboard attached to your device. 

Chief among this flexibility is the ability to attach this keyboard to three devices and switch through them with the push of a button. It makes it supremely convenient to move between your iPad, MacBook, or even your phone. The keyboard also comes with a full slate of keys that make the keyboard more convenient, including playback control, brightness keys, and volume keys. 

While this keyboard does not attach to your iPad Pro, it is still supremely easy to bring along with you anywhere you go. That’s because the compact keyboard weighs less than a pound and comes in a compact and sturdy build that easily fits on your lap or on a tabletop. 

Some might not like that this keyboard requires two AAA batteries (we recommend rechargeables) rather than uses an internal battery; however, the low power demands mean you shouldn’t need to replace those batteries for more than a year, even with heavy use. 

What to consider when shopping for an iPad Pro keyboard

There are many factors we consider when deciding which iPad keyboards to recommend. Here are the ones we weighted most heavily when making our decisions:

Your iPad Pro usage

Will you be typing, or do you plan on doing some drawing as well? A keyboard attached to your iPad can be cumbersome when you are using your iPad as a tablet and not typing. If so, consider a folio with a keyboard that can detach or a completely external keyboard that allows unhindered use when you’re not typing. 

Typing requirements

Not all keyboards are created equal. If you want to do long word processing on your iPad, ensure you get a more robust keyboard that will let you type comfortably for extended periods. If you are just using your iPad keyboard as an in between, it might be more worthwhile to save money and opt for a cheaper, less ergonomic keyboard. 

The level of iPad protection

Consider if you will be treating your keyboard as an iPad case as well. If so, how much protection do you need? If you are constantly throwing your iPad in and out of your bag, make sure you have back and edge protection. If, however, it is just an in-between workstation at home, you may be able to get away with a keyboard that does not offer any, or just minimal, protection. 

FAQs

Final thoughts on the best iPad Pro keyboards

• Best overall: Logitech Combo
• Best splurge: Apple Magic Keyboard for iPad
• Best value: Zagg Pro Keys
• Best design: Brydge 12.9 Pro+ Wireless Keyboard
• Best budget: Logitech K380

An iPad Pro keyboard isn’t a necessary accessory, but it does open up use cases for the tablet that wouldn’t otherwise be possible. It will have the biggest impact on your typing speed, and many popular applications have begun building keyboard shortcuts into their software to make it easier (and faster) to access key functions. And iPad Pro keyboards with trackpads turn the iPad into a legitimate laptop competitor in many instances; after all, the latest generation of these machines run on the same processor as the newest MacBooks. If you want to get the most out of Apple’s tablet, we strongly suggest pairing it with a keyboard.

To understand how electric cars work, it helps to keep in mind the ways in which they’re similar to regular gas-burning vehicles. They’re cousins from different generations, not machines from different universes. If you drive, you know the drill: Press down on the pedal with your right foot to get moving, point the vehicle where you want to go, maybe put on some music, and try not to crash. 

“An EV has four wheels,” says Chad Kirchner, the founder of evpulse.com, a news and information site about electric vehicles. “There’s a start button, there’s an accelerator pedal, there’s a brake. In a lot of ways, an EV—and the EV driving experience—is identical to a gas-powered experience.” 

That said, there are key differences in engineering, design, maintenance, and performance between electric cars and internal combustion engine (ICE) vehicles.   

Electric car battery system 101

To begin with, an ICE vehicle relies on a tank of gasoline or diesel to get the energy it needs. An EV, on the other hand, requires a battery system, which consists of a multitude of individual cells. And just like a gas tank, the battery cells store energy. 

“But [a battery cell] also produces power—and the power is a result of the voltage of that particular cell, and the current it’s able to output,” says Charles Poon, the global director of Electrified Systems Engineering at Ford, which makes the Mach-E, the F-150 Lightning, and the E-Transit electric vehicles. He describes the battery as the car’s heart.

Battery design in EVs will differ between automakers, and one of the main ways is the shape of their cells. To make things a bit more tangible, consider the Mach-E, an electric car that descends from a famous line of gas-burning vehicles that gave birth to the term “pony car.” The cells in the Mach-E are in pouch form, whereas other batteries in the market have cylindrical cells (Tesla uses those) or prismatic cells. A Mach-E battery system has hundreds of cells.

The lithium-ion-based electric car batteries can also have slightly different chemistries. For example, a Mach-E can come with nickel, cobalt, and manganese (NCM) batteries or lithium iron phosphate (LFP) batteries. The former are known for being able to hold power for longer and performing well in cold temperatures, while LFP batteries are less expensive and can charge up faster. 

How do electric motors work? 

The term AC/DC is not only the name of an Australian rock band, but also describes two forms of electricity: alternating current (AC) and direct current (DC). Both types of power are important for electric cars to work.

The electricity coming out of your wall outlet at home is in AC form, but batteries store their energy in DC form. Because of this, electric cars have a component known as a charger that takes the AC power flowing into the vehicle and switches it to the more battery-friendly DC. A quicker way to charge up one of these cars is by using a DC fast charger, which provides the car with juice in DC form, so the car doesn’t have to convert it. 

“It bypasses the AC charger [in the car], and goes directly into the battery,” Poon explains. 

[Related: What an electric vehicle’s MPGe rating really means]

So the batteries store power in DC form, but there’s a twist: electric motors work with AC power. This means the vehicle has to transform electricity yet again, which it does using a traction inverter that converts the DC back into AC. “And then that is what actually ends up spinning the electric motor, producing power,” Poon adds.  

There are two key components in an electric motor: a stator and a rotor. The rotor sits inside the stator and rotates using the wonders of magnetism that kick in when AC power hits the motor. 

“We send what we call three phases of alternating current through a stator that has wires that are wound radially, sequentially, around the stator,” he explains. “And we are able to create a rotating magnetic field—so the magnetic field rotates, and it pulls the rotor along with it.” 

And voilá! After passing through some gearing, that rotation turns the wheels on your electric vehicle. 

While an ICE car has one engine, Kirchner, from evpulse.com, notes that electric vehicles in the market can have as many as four motors. For example, the rear-wheel drive version of a Mach-E uses one motor, while the all-wheel drive version uses two—one for the front and one for the back. At the other end of the spectrum, a Rivian R1T can have as many as one motor per wheel.

The pros and cons of driving an electric vehicle

Could you imagine if taking your foot off the gas pedal in an ICE vehicle magically made more gasoline appear in the tank? Something like that happens in an EV.

This cool trick is called regenerative braking, and allows drivers to start slowing down not by pushing the brake pedal as in regular cars, but by taking their foot off the accelerator. Don’t worry—that brake pedal is still there when you need it. In one-pedal or regen mode, things happen in reverse: the wheels turn the motors so they act like generators and send power back to the batteries. 

“You are actually taking the vehicle momentum and putting it back in as chemical energy into the battery,” Poon says.

Mach-E Chief Engineer Donna Dickson says one-pedal driving still remains an unfamiliar technique for drivers, but notes that it helps prevent wear on the brakes while also adding battery charge.

The power source is not the only difference between electric cars and ICE vehicles. There are other details that set the two apart. For example, Kirchner says that while combustion engines have to rev a little to make torque, EV motors make all of their torque from a complete standstill. This results in great acceleration. “Around town, even electric cars that you would not consider sporty by looking at them feel very quick, which makes them excellent city cars,” he continues. 

Another benefit of driving an electric vehicle is that they need less maintenance. There’s no need for an oil change, although their heavier weight means their tires experience more wear and tear. 

On the downside, you can’t charge up the batteries as rapidly or as easily as gasoline goes into a tank, but if you can charge at home, you have a unique perk: “You start every morning with a full tank,” says Kirchner. But that doesn’t always come as easy as it sounds.

“If you are an EV owner, it’s pretty much imperative at this point to have someplace to plug in and charge overnight,” says Paul Waatti, manager of industry analysis for AutoPacific. However, “there’s a good portion of America that doesn’t live in a single-family home.” People residing in condos, apartments, and other residential setups will have a more challenging time finding a charger to plug in their cars overnight. As for public chargers, Waatti says those networks are “very far off from being seamless at this point,” meaning there are too few and many don’t work properly.

The Mac menu bar is iconic. With the Apple logo in the top-left and the text menu for the current application to the right, this feature has been at the top of the screen of every Apple computer since 1981. The last big update came 10 years later when the Cupertino company added icons to the right side. The menu bar has more-or-less looked the same ever since. 

But just because Apple hasn’t really changed the menu bar in the last 40 years doesn’t mean you can’t change it now. There are all kinds of subtle ways you can take control of how the menu bar looks and functions, starting with the order of those icons in the top-right corner. Here’s how you can customize the Mac menu bar to work just the way you want. 

Organize your Icons

It’s definitely not obvious or intuitive, so it’s ok if you didn’t know that you can rearrange your menu bar icons: Just hold the Command key and drag your icons into whatever order you like. This works for every icon except three: the Control Center icon, Siri, and the clock. Those stay in the top-right corner no matter what, but everything else is fair game. 

Customize your system icons

By default, the Mac includes icons for Siri, Wi-Fi, and your battery in the menu bar. If you’d rather not see those icons all the time, don’t worry: just head to System Settings. You can get there by opening the dock icon with the gears, or clicking the Apple logo in the top-right corner and then choosing System Settings in the emerging menu. Head to Control Center on the sidebar to configure which system icons you want to show up in the menu bar. This can be a quick way to remove clutter or add relevant information. 

[Related: 4 tips and hidden settings that will speed up macOS]

You can also customize the clock from here, allowing you to add the date, day of the week, and even the seconds. You could also replace the text showing the time with an icon of an old-school analogue clock, if you like. 

What you can’t tweak here is icons for your applications.

Stop the transparency

The menu bar, by default, is slightly transparent, allowing a little bit of your desktop wallpaper to bleed through. If you don’t like this effect (and the other transparency in the macOS operating system) head to System Settings, Accessibility, and click Display. Check Reduce transparency and your menu bar will be solid white in light mode and solid black in dark mode. 

You can also customize the size a little bit—beside Menu bar size check Large and the text in the menu bar will be a slightly bigger. 

Hidden Bar is a free application for hiding the clutter

Way too many applications insist on putting something up in the menu bar, so the top-right corner of your screen can quickly look cluttered. The worst part is that there’s no native way to hide icons in macOS the way you can in Windows, for example, where you can move them to a secondary tray. On the Mac, meanwhile, the only way to hide an icon for a given application is to dig around in the app settings and hope it offers a solution—it’s a hit or miss sort of situation.

Fortunately, there’s a free application called Hidden Bar that brings this feature to the Mac. Download it from the App Store so you can hide icons by dragging them to the left while holding Command. You’ll be able to see all hidden icons by clicking the right-pointing arrow. 

It’s a very simple application that gets the job done. Why Apple hasn’t built something like this into the operating system, I will never understand. 

Bartender hides icons and changes how the menu bar looks

For many the free Hidden Bar will do the job, but Bartender ($16) offers customization options the former doesn’t have. 

Yes, you can hide icons by dragging them to the left, just like you can with Hidden Bar. But you can also create a custom rule for when to display certain icons. Want to see the battery icon, but only when you’re not plugged in? Bartender can do that, and also show you the Wi-Fi icon only when you’re not connected to a network.

You can also change the look of the menu bar with this application—apply a color tint or add a border. You can bring back the drop shadow that Apple recently removed, or even round the corners of the menu bar so it looks less like a block. 

[Related: Master your Mac by creating custom keyboard shortcuts]

Basically, if you want to tweak every aspect of how your menu bar works, Bartender is the application you’re looking for. 

Hide the menu bar altogether

Customizing the menu bar is all well and good, but what if you just wish it would go away? You can hide the menu bar in System Settings. Head to Control Center and scroll down to the bottom. In the dropdown menu next to Automatically hide and show the menu bar, select Always. From now on, the menu bar will only show up when you move your mouse to the top of the screen. The rest of the time, it’ll stay out of the way. This means you get a bit more screen real estate, allowing you to focus on the task at hand instead of whatever the icons the menu bar displays.

If you remember chatting with SmarterChild back on AOL Instant Messenger back in the day, you know how far ChatGPT and Google Bard have come. But how do these so-called chatbots work—and what’s the best way to use them to our advantage?

Chatbots are AI programs that respond to questions in a way that makes them seem like real people. That sounds pretty sophisticated, right? And these bots are. But when it comes down to it, they’re doing one thing really well: predicting one word after another.

So for ChatGPT or Google Bard, these chatbots are based on what are called large language models. That’s a kind of algorithm, and it gets trained on what are basically fill-in-the-blank, Mad-Libs style questions. The result is a program that can take your prompt and spit out an answer in phrases or sentences.

But it’s important to remember that while they might appear pretty human-like, they are most definitely not—they’re only imitating us. They don’t have common sense, and they aren’t taught the rules of grammar like you or I were in school. They are also only as good as what they were schooled on—and they can also produce a lot of nonsense.

To hear all about the nuts and bolts of how chatbots work, and the potential danger (legal or otherwise) in using them, you can subscribe to PopSci+ and read the full story by Charlotte Hu, in addition to listening to our new episode of Ask Us Anything.

If you live in and around Gulkana, Alaska and recently saw some eerie lights in the sky—don’t worry; they were all part of a science experiment. Earlier this week, researchers from the University of Alaska Fairbanks and several other US institutions created artificial auroras by sending radio pulses into the Earth’s ionosphere using HAARP (High Frequency Active Auroral Research Program) transmitters on the ground. The frequencies of these transmissions were between 2.8 and 10 megahertz. 

These transmitters act as heaters that excite the gasses in the upper atmosphere. When the gasses “de-excite,” they produce an airglow between 120 and 150 miles above ground, according to a notice about the project issued by the HAARP team. This is similar to how charged particles from the sun interact with gasses in the upper atmosphere to create natural auroras; the charged particles are steered by the Earth’s magnetic field to the north and south poles to form aurora borealis and aurora australis. Compared to those light displays, the artificial auroras are much weaker. 

So why did the researchers do all this? Studying this artificial airglow may provide insights on what happens when real aurora lights appear.

If you noticed a faint red or green splotch in the sky above Alaska between November 4 and November 8, chances are good that you saw the experiment in progress. HAARP also notes in its FAQ that these ionosphere-heating experiments have no detectable effects on the environment after 10 minutes or so. 

[Related: Why NASA will launch rockets to study the eclipse]

Additionally, the team also wants to understand how these superheated gasses in the ionosphere interact with each other. Insights into these dynamics could inform collision detection and avoidance features for satellite systems. Gathering more intel on auroras and other upper atmosphere phenomena like it can help scientists see how weather and particles from space are interacting with the environment around Earth, and how energy is transferred during these events. 

Disturbing the ionosphere is not the only way to study auroras. Launching rockets into the ionosphere, which sits just at the edge of space, is another popular approach. 

The goal of HAARP is to research the physical and electrical properties of the Earth’s ionosphere as it pertains to surveillance, military and civilian communications, as well as radar and navigation systems. Outside of studying auroras, HAARP has used its antenna array to peer inside a passing asteroid, observe solar storms, and conduct other tests related to space physics. Beyond the Earth, the team’s ambitions extend to the moon and to Jupiter. 

HAARP has had an interesting history. Despite conducting serious science, around 2014, controversy and conspiracy brewed around the program’s mysterious antenna field, then run by the US military, prompting scientists to host open houses with the public explaining what they can and can’t do with their technology. Its image problem remains despite the changes in ownership over the years.

Collectors are apparently only interested in very specific pieces of Apple history. While a first generation 8GB iPhone in original packaging sold on November 8 for nearly $20,500, an Apple rainbow logo sign which once hung atop the company’s Cupertino Corporate Headquarters failed to reach its minimum $30,000 auction bid on Wednesday.

[Related: A first generation iPhone just sold for 317 times its original sticker price.]

Although technically not Apple’s first logo—a detailed, vintage illustration of Isaac Newton seated underneath a tree—the six-hued fruit image designed by graphic designer Rob Janoff in 1977 quickly grew as instantly recognizable as the Nike “Swoop” and McDonald’s “Arch.” According to Bonhams auction house lot description, Steve Jobs reportedly enjoyed Janoff’s minimalist design, particularly the bite mark included to ensure consumers wouldn’t potentially mistake it for a tomato. Jobs was also firm about the multicolor scheme, believing it would “humanize” the company. Apple’s CEO apparently had a change of heart by 1998, when the company updated to the monochromatic logo largely still seen today.

But even shelling out tens of thousands of dollars for the roughly 46-by-50 inch signage wouldn’t have meant its new owner received the logo in mint condition, however. The lot description notes “slight peeling” near the color stripes’ edges, along with “craquelure” in certain areas and “general outdoor wear,” which is probably to be predictable after years hanging atop a building near California’s Highway 280.

Meanwhile, people appeared much more interested in a 8GB first generation iPhone within its original packaging. Finally sold for $20,450, the lot is in much better shape—and has Drew Carey to partially thank for it. Roger Dobkowitz, a longtime producer on The Price Is Right, received the then-revolutionary smartphone as a gift from Carey shortly after the comedian became the game show’s new host in 2007.

[Related: Here’s a look at Apple’s first augmented reality headset.]

“Everyone was quite ecstatic… it had been released just three weeks earlier and it was a big thing in the news,” Dobkowitz said in a statement for Bonhams. Despite all the hype, however, Dobkowitz never bothered to use his at-the-time $499 gift, let alone open it.

“I did not like cell phones, and had no intention of using it,” he explained, adding that he tossed the iPhone in a desk drawer, and never thought about it again “until years later.” By that point, Apple’s iPhone was firmly established as a cultural touchstone product even a cell phone naysayer like Dobkowitz could recognize. The television producer eventually fished out his workplace gift from the drawer, and transferred the likely (already price-inflated) iPhone into a safe, where it remained until very recently.

Dobkowitz’ iPhone is far from the first to hit the auction block. This year alone, another first generation model sold for over $63,000 in February, while a mint condition, factory sealed, first generation 4GB iPhone formerly belonging to an Apple engineering team member auctioned at nearly $200,000 in July.

Maybe in a few years’ time, the Apple logo will finally find a new home. Perhaps its current owners can call Drew Carey for some advice.

This week, LTA Research revealed Pathfinder 1, a prototype electric airship, to the public. According to TechCrunch, the company founded by Sergey Brin will spend the next year putting its airship through airworthiness testing at Moffett Field, home of NASA’s Ames Research Center, and out over the seas of the southern San Francisco Bay. If all goes well, airships could one day be used for climate-friendlier air travel, cargo transport, and humanitarian aid missions. 

Pathfinder 1, LTA Research’s first prototype, is 400 feet long and 66 feet wide. That’s more than 150 feet longer than an Airbus A380, and is apparently the largest aircraft to take to the skies since the ill-fated Hindenburg in the 1930s. (Though, at over 800 feet long, the Hindenburg would dwarf Pathfinder 1.) 

Instead of explosive hydrogen, Pathfinder 1 uses helium as its lighter-than-air lift gas. The airship has 13 rip-stop nylon gas bags inside its rigid carbon-fiber and titanium frame that are continuously monitored using LIDAR to ensure the airship is properly balanced, buoyant, and performing well. LTA is obviously angling for nothing to go wrong, but just in case, the surface of the airship is coated with Tedlar, a laminated, strong, lightweight, and, crucially, non-flammable material.

[Related: The biggest hot air balloon in the US was built to carry skydivers]

While the helium gets Pathfinder 1 in the air, it moves around thanks to 12 electric motors that are powered by diesel generators and batteries. The motors can drive the airship at up to 75 mph and can rotate from +180º to -180º to allow it to maneuver carefully. The pilots steer using a joystick and fly-by-wire system that automatically integrates with sensor feedback data to control all the motors. 

Despite its massive size, Pathfinder 1 will only be able to carry a relatively small amount of cargo. Depending on how tests go and the specific requirements of the situation, LTA expects the airship to have a payload of between 4,400 and 11,000 pounds. By contrast, a C-17 Globemaster can carry almost 180,000 pounds. The advantage of an airship, then, isn’t so much in what it can do, but in what other aircraft can’t. 

LTA Research highlights the humanitarian angle. As its FAQs explain, “airships will have the ability to complement, and even speed up, humanitarian disaster response and relief efforts, so that many more lives can be saved. Airships do not require aviation infrastructure like airstrips and landing zones, allowing them to deliver food, equipment, supplies, and other life-saving aid to areas impacted by natural disasters.” It also suggests that if cell towers are knocked down, airships could hover in the area equipped with the necessary radio equipment and get service back online.

[Related: RIP Loon, Google’s balloon-based cellular network]

For now though, Pathfinder 1 has much simpler objectives: get through flight testing. The FAA’s airworthiness certificate mandates that it is tethered to a mobile mast for ground testing, before conducting low-level flights at up to 1,500 feet. If all goes well in California, it will then be taken to the historic Goodyear Airdock where LTA Research is already developing Pathfinder 3, another prototype that, at 590 feet long, will have even more potential for carrying humanitarian aid.

This article was originally featured on The Conversation.

In 1976, beloved chef, cookbook author and television personality Julia Child returned to WGBH-TV’s studios in Boston for a new cooking show, “Julia Child & Company,” following her hit series “The French Chef.” Viewers probably didn’t know that Child’s new and improved kitchen studio, outfitted with gas stoves, was paid for by the American Gas Association.

While this may seem like any corporate sponsorship, we now know it was a part of a calculated campaign by gas industry executives to increase use of gas stoves across the United States. And stoves weren’t the only objective. The gas industry wanted to grow its residential market, and homes that used gas for cooking were likely also to use it for heat and hot water.

The industry’s efforts went well beyond careful product placement, according to new research from the nonprofit Climate Investigations Center, which analyzes corporate efforts to undermine climate science and slow the ongoing transition away from fossil fuels. As the center’s study and a National Public Radio investigation show, when evidence emerged in the early 1970s about the health effects of indoor nitrogen dioxide exposure from gas stove use, the American Gas Association launched a campaign designed to manufacture doubt about the existing science.

As a researcher who has studied air pollution for many years–including gas stoves’ contribution to indoor air pollution and health effects–I am not naïve about the strategies that some industries use to avoid or delay regulations. But I was surprised to learn that the multipronged strategy related to gas stoves directly mirrored tactics that the tobacco industry used to undermine and distort scientific evidence of health risks associated with smoking starting in the 1950s.

Manufacturing controversy

The gas industry relied on Hill & Knowlton, the same public relations company that masterminded the tobacco industry’s playbook for responding to research linking smoking to lung cancer. Hill & Knowlton’s tactics included sponsoring research that would counter findings about gas stoves published in the scientific literature, emphasizing uncertainty in these findings to construct artificial controversy, and engaging in aggressive public relations efforts.

For example, the gas industry obtained and reanalyzed the data from an EPA study on Long Island that showed more respiratory problems in homes with gas stoves. Their reanalysis concluded that there were no significant differences in respiratory outcomes.

The industry also funded its own health studies in the early 1970s, which confirmed large differences in nitrogen dioxide exposures but did not show significant differences in respiratory outcomes. These findings were documented in publications where industry funding was not disclosed. These conclusions were amplified in numerous meetings and conferences and ultimately influenced major governmental reports summarizing the state of the literature.

This campaign was remarkable, since the basics of how gas stoves affected indoor air pollution and respiratory health were straightforward and well established at the time. Burning fuel, including natural gas, generates nitrogen oxides: The air in Earth’s atmosphere is about 78% nitrogen and 21% oxygen, and these gases react at high temperatures.

Nitrogen dioxide is known to adversely affect respiratory health. Inhaling it causes respiratory irritation and can worsen diseases such as asthma. This is a key reason why the U.S. Environmental Protection Agency established an outdoor air quality standard for nitrogen dioxide in 1971.

No such standards exist for indoor air, but as the EPA now acknowledges, nitrogen dioxide exposure indoors also is harmful.

How harmful is indoor exposure?

The key question is whether nitrogen dioxide exposure related to gas stoves is large enough to lead to health concerns. While levels vary across homes, scientific research shows that the simple answer is yes–especially in smaller homes and when ventilation is inadequate.

This has been known for a long time. For example, a 1998 study that I co-authored showed that the presence of gas stoves was the strongest predictor of personal exposure to nitrogen dioxide. And work dating back to the 1970s showed that indoor nitrogen dioxide levels in the presence of gas stoves could be far higher than outdoor levels. Depending on ventilation levels, concentrations could reach levels known to contribute to health risks.

Despite this evidence, the gas industry’s campaign was largely successful. Industry-funded studies successfully muddied the waters, as I have seen over the course of my research career, and stalled further federal investigations or regulations addressing gas stove safety.

This issue took on new life at the end of 2022, when researchers published a new study estimating that 12.7% of U.S. cases of childhood asthma–about one case in eight–were attributable to gas stoves. The industry continues to cast doubt on gas stoves’ contribution to health effects and fund pro-gas stove media campaigns.

A concern for climate and health

Residential gas use is also controversial today because it slows the ongoing shift toward renewable energy, at a time when the impacts of climate change are becoming alarmingly clear. Some cities have already moved or are considering steps to ban gas stoves in new construction and shift toward electrifying buildings.

As communities wrestle with these questions, regulators, politicians and consumers need accurate information about the risks of gas stoves and other products in homes. There is room for vigorous debate that considers a range of evidence, but I believe that everyone has a right to know where that evidence comes from.

The commercial interests of many industries, including alcohol, tobacco and fossil fuels, aren’t always compatible with the public interest or human health. In my view, exposing the tactics that vested interests use to manipulate the public can make consumers and regulators savvier and help deter other industries from using their playbook.

After over half a century of loyal service, the world’s last remaining Super Guppy aircraft continues to dutifully transport NASA’s gigantic rocket parts in its cavernous, hinged cargo bay. On Tuesday, the Huntsville International Airport posted a video and accompanying images to social media of the rotund plane arriving from Kennedy Space Center. Perhaps somewhat unsurprisingly, it sounds like a prop plane of that size can make a huge, rich racket on the tarmac.

[Related: Artemis II lunar mission goals, explained.]

Aboard the over 50-ton (when empty), turboprop plane this time around was the heat shield that protected last year’s Artemis I Orion spacecraft. The vital rocketry component capable of withstanding 5,000 degrees Fahrenheit resided in the Super Guppy’s 25-foot tall, 25-foot wide, 111-foot long interior during a nearly 690-mile journey to the Alabama airport, after which it was transported a few miles down the road to the Marshall Space Flight Center. From there, a team of technicians will employ a specialized milling tool to remove the heat shield’s protective Avcoat outer layer for routine post-flight analysis, according to NASA.

The Super Guppy is actually the third Guppy iteration to lumber through the clouds. Based on a converted Boeing Stratotanker refueling tanker and designed by the now defunct Aero Spacelines during the 1960s, an original craft called the Pregnant Guppy was supplanted by its larger Super Guppy heir just a few years later. This updated plane included an expanded cargo bay, alongside an incredibly unique side hinge that allows its forward section to open like a pocket watch. A final Super Guppy Turbine debuted in 1970, and remained in use by NASA for over 25 years. In 1997, the agency purchased one of two newer Super Guppy Turbines built by Airbus. This Guppy is the current and only such hefty boy gracing the skies. With its bulky profile, the Super Guppy’s travel specs are pretty impressive—it’s capable of flying as high as 25,000 feet at speeds as fast as 250 nautical miles per hour.

Last PopSci checked in on the Super Guppy’s journeys was back in 2016, when it transported an Orion crew capsule potentially destined for a much further trip than the Artemis missions’ upcoming lunar sojourns—Mars. According to Digital Trends, the Super Guppy’s next flight could occur sometime next year ahead of NASA’s Artemis II human-piloted lunar flyby.

“Although much of the glory of America’s space program may be behind it, the Super Guppy continues to be one of the only practical options for oversized cargo and stands ready to encompass a bigger role in the future,” reads a portion of NASA’s official description.

Until then, feel free to peruse the official, 74-page Super Guppy Transport User’s Guide.

There’s a new feature in the Google Bard AI assistant: connections to your other Google apps, primarily Gmail and Google Drive, called Bard Extensions. It means you can use Bard to look up and analyze the information you have stored in documents and emails, as well as data aggregated from the web at large.

Bard can access other Google services besides Gmail and Google Drive as well, including YouTube, Google Maps, and Google Flights. However, this access doesn’t extend to personal data yet, so you can look up driving directions to a place on Google Maps, but not get routes to the last five restaurants you went to.

If that sets alarm bells ringing in your head, Google promises that your data is “not seen by human reviewers, used by Bard to show you ads, or used to train the Bard model,” and you can disconnect the app connections at any time. In terms of exactly what is shared between Bard and other apps, Google isn’t specific.

[Related: The best apps and gadgets for a Google-free life]

Should you decide you’re happy with that trade-off, you’ll be able to do much more with Bard, from looking up flight times to hunting down emails in your Gmail archive.

How to set up Bard Extensions, and what Google can learn about you

If you decide you want to use Bard Extensions, open up Google Bard on the web, then click the new extensions icon in the top right corner (it looks like a jigsaw piece). The next screen shows all the currently available extensions—turn the toggle switches on for the ones you want to give Bard access to. To revoke access, turn the switches off.

Some prompts (asking about today’s weather, for instance) require access to your location. This is actually handled as a general Google search permission in your browser, and you can grant or revoke access in your privacy settings. In Chrome, though, you can open google.com, then click the site information button on the left end of the address bar (it looks like two small sliders—or a padlock if you haven’t updated your browser to Chrome 119).

From the popup dialog that appears, you can turn the Location toggle switch off. This means Google searches (for restaurants and bars, for example) won’t know where you are searching from, and nor will Bard.

As with other Google products, you can see activity that’s been logged with Bard. To do so, head to your Bard activity page in a web browser to review and delete specific prompts that you’ve sent to the AI. Click Choose an auto-delete option, and you can have this data automatically wiped after three, 18, or 36 months. You can also stop Bard from logging data in the first place by clicking Turn off.

There’s more information on the Bard Privacy Help Hub. Note that by using Bard at all, you’re accepting that human reviewers may see and check some of your prompts, so Google can improve the response accuracy of its AI. The company specifically warns against putting confidential information into Bard, and any reviewed prompts won’t have your Google Account details (like your name) attached to them.

Prompts reviewed by humans can be retained by Google for up to three years, even if you delete your Bard activity. Even with Bard activity-logging turned off, conversations are kept in Bard’s memory banks for 72 hours, in case you want to add related questions.

Tips for using Bard Extensions

Extensions are naturally integrated into Bard, and in a lot of cases, the AI bot will know which extension to look up. Ask about accommodation prices for the weekend, for example, and it’ll use Google Hotels. Whenever Bard calls upon an extension, you’ll see the extension’s name appear while the AI is working out the answer.

Sometimes, you need to be pretty specific. A prompt such as “what plans have I made over email with <contact name> about <event>?” will invoke a Gmail search, but only if you include the “over email” bit. At the end of the response, you’ll see the emails (or documents) that Bard has used to give you an answer. You can also ask Bard to use specific extensions by tagging them in your prompt with the @ symbol—so @Gmail or @Google Maps.

[Related: All the products Google has sent to the graveyard]

Bard can look up information from emails or documents, and can read inside PDFs in your Google Drive. For example, tell it to summarize the contents of the most recent PDF in your Google Drive, or the contents of recent emails from your kid’s school, and it will do just that. Again, the more specific you can be, the better.

In terms of YouTube, Google Maps, Google Flights, and Google Hotels, Bard works more like a regular search engine—though you can combine searches with other prompts. If you’re preparing a wedding speech, for example, you can ask Bard for an outline as well as some YouTube videos that will give you inspiration. If you’re heading off on a road trip, you could combine a prompt about ideas on what to pack with Google Maps driving directions.

We’ve found that some Bard Extensions answers are a bit hit or miss—but so are AI chatbots in general. At certain times, Bard will analyze the wrong emails or documents, or will miss information it should’ve found, so it’s not (yet) something you can fully rely on. In some situations, you’ll get better answers if you switch over to Google Drive or YouTube and run a normal search from there instead—file searches based on dates, for instance, or video searches limited to a certain channel.

At other times, Bard is surprisingly good at picking out information from stacks of messages or documents. You can ask Bard “what’s the most cheerful email I got yesterday?” for example, which is something you can’t do with a standard, or even an advanced Gmail search. It’s well worth trying Bard Extensions out, at least briefly, to see if they prove useful for the kinds of information retrieval you need.

Making the iPhone keyboard bigger is one of the easiest ways to make Apple’s phones easier to use. Doing so will allow you to see the keys more clearly, providing a more comfortable typing experience and reducing your chances of pressing the wrong characters. This is particularly helpful if you have larger fingers or visual impairments.

Follow along with our step-by-step instructions on how to enlarge the keyboard on your iPhone, and stick around for additional iPhone keyboard settings tips and tricks that should improve your ability to interact with your iOS device.

How to make the iPhone keyboard bigger, instantly

The quickest way to get a larger iPhone keyboard is to rotate your device until it’s horizontal. This will automatically switch the screen orientation to landscape, providing a wider, more spacious keyboard for easier typing.

If the keyboard won’t turn sideways, your phone is locked in portrait orientation. To remedy this on an iPhone without a Home button, swipe down from the top right corner to open the Control Center. If you have a phone with a Home button, swipe up from the bottom edge of your screen to get to the same place. Then tap the Portrait Orientation Lock button (a padlock with an arrow around it) to ensure it’s off—it will display in red if on and locked.

Set the keyboard to display only uppercase letters

The iPhone keyboard alternates between lowercase and uppercase letters depending on the shift setting, but the lowercase characters can be harder to see. To make each key easier to identify, you can tell your iPhone to always display uppercase keys, simulating a physical keyboard with all keys printed in capital letters. You will still be able to type in lowercase letters as long as shift or caps lock is off.

[Related: 24 iPhone settings that feel like secrets]

To see only uppercase letters, go to Settings, tap Accessibility, then Keyboards. Toggle off the switch next to Show Lowercase Keys, and you’ll make the keyboard letters bigger.

Make your iPhone keyboard bold

Bold type is easier to see, making text and letters stand out. To make your iPhone keyboard more bold, and therefore, bigger, go to the Settings app and select Display & Brightness. From there, tap Text Size and hit the toggle switch next to Bold Text. Now, the letters on your keyboard and the text you type and see on your phone will be bold.

Switch to Zoom view

The iPhone’s Zoom function will allow you to magnify the entire screen, making it easier to see and interact with the content. Just be warned: enabling Zoom will activate it immediately, and you may struggle to go back to normal. If you need to turn Zoom off, double-tap the screen with three fingers. Now that we’ve hopefully prevented a stressful situation, you can enable the feature: Go to the Settings app, select Accessibility, and turn on the toggle switch next to Zoom.

From there, you will see instructions for controlling magnification with finger taps.

You can also adjust the Zoom level according to your preference:

• Follow Focus: Stays focused on typed and selected text.
• Smart Typing: Zooms into the text box to make it easier to see when typing.
• Keyboard Shortcuts: If you’ve connected an external keyboard to your iPhone by enabling full keyboard access, this will let you use shortcuts on that keyboard to control Zoom.
• Zoom Controller: Lets you slide your finger around the screen to choose what Zoom focuses on.
• Zoom Region: Allows you to use Full Screen Zoom or Window Zoom (partial screen zoom).
• Zoom Filter: Customizes the color of your screen when Zoom is enabled. Choose from: None, Inverted, Grayscale, Grayscale Inverted, or Low Light.
• Maximum Zoom Level: Drag the slider to adjust the level of Zoom.

Use a third-party keyboard app

Maybe the iPhone keyboard just doesn’t cut it, and you’d prefer something else. Thankfully, customizing your iPhone by adding a third-party keyboard is simple. First, go to the App Store and search for one of the best keyboard apps. After you install the one you want, go to the iPhone’s Settings app, tap General, Keyboard, and hit Keyboards.

Next, select Add New Keyboard. Find the third-party keyboard app on the list and tap on it to add it to your active keyboards. To use your new keyboard, open the app itself and make any modifications that will make the keyboard bigger.

Boost your iPhone’s text size

Increasing the size of the text on your iPhone’s screen can make it easier to see what you’re typing (and reading). To change your iPhone’s text size, go to the Settings app and select Display & Brightness. There, tap Text Size and adjust the slider to make the text larger.

This won’t change the size of the keyboard, but it’s still a useful tip if you’re struggling to see what’s written on your iPhone’s screen.

Change your iPhone keyboard sensitivity

If you’re having trouble typing on your iPhone, you may want to consider adjusting the keyboard’s sensitivity. This will determine how your phone responds to how long you press and hold your finger on the screen. To find it, got to Settings > Accessibility > Touch, then tap Haptic Touch.

With hundreds of thousands of Android games on the Google Play Store, it can be tricky to find ones that are suitable to play. Often, the games we see advertised the most for Android phones and tablets are also the most predatory. Avoiding games designed more to take our cash than to entertain us is difficult, but we can help by recommending five of the best Android games that break the mold and still provide plenty of fun.

 Super Auto Pets

Super Auto Pets is an answer to auto-battling games like Hearthstone: Battlegrounds, Riot’s Team Fight Tactics, and Marvel Snap. The game has a clear monetization scheme and instantaneous unlocks, yet still holds onto the addictive gameplay loop the aforementioned auto-battlers have. But the obsession comes from fun and achievements, not grinding out currency and unlocks.

During gameplay, you’ll assemble a team of cute animals (including a dinosaur or two), feed them, and head off to battle. As the primary game mode is asynchronous, it’s a perfect game for busy adults. You won’t have to hurry through turns if you dip into play intermittently throughout the workday. If you have time, however, you can sit down for a ranked match, which plays like more typical multiplayer online games. What animals (and food) you play with are determined by sets, which can be purchased in full with a single direct purchase, no “gems” or other in-game currency required. The first set is free and you can eventually play with all animals for free via weekly random and/or curated sets.

Super Auto Pets is free, and you can buy additional packs in the app.

2. Vampire Survivors

Vampire Survivors became a cult classic on PC during the summer of 2023. With graphics that can be described as “1998 DOS freeware” and a user interface defined by only one word—chaotic—this is definitely a stylized game. The effect is outstanding, however, and a satisfying game loop quickly seals players within its grasp.

Each session starts with a character and a weapon or two, automatically flying about the screen. As your weapon hits enemies who increasingly crowd around you, numbers begin to fly everywhere, levels rise, and resources accumulate. Regular pauses in the action give you a chance to breathe and plot, while also giving you access to items that will improve your build. As time progresses, so does the intensity of the opposition, with the final bits of action proving the true power of your build and if you’re worthy of unlockables.

Vampire Survivors is free with in-app purchases.

3. Dominion

Dominion is a classic board game. Now, it has a new Android app edition, suitable for both new and recurring players. Dominion is a deck-builder that emphasizes trade-offs and long-term planning. Each turn, you collect cards that either boost your score or your potential to grab even better cards later. Grabbing early-game, high-point cards while you can will always feel good, for example, but seeing those cards (dead weight in your hand) again and again throughout a match can feel exhausting.

As mentioned, this game originates from older source material. However, this digital rendition is a fairly new implementation of the game, and at the time of this writing, it remains in early access. As a result, if you’ve been put off by other mobile implementations of board and card games of this era, you should strongly consider coming back for Dominion to see if a new generation of graphics, UI innovations, and controls can get you in the game.

Dominion is free, and you can buy expansions in the app.

4. Peglin

Take PopCap’s Peggle, toss in a Slay the Spire overworld and character development system, and throw in some unique thematic arcs of its own and you have Peglin. Essentially, the game’s core loop is you—depicted as a green goblin with pointy ears—throwing rocks and orbs through a board to hit pegs. To oversimplify greatly, the more pegs you hit, the more damage you do to oncoming monsters. It’s a hit-or-be-hit world. After battles end, you get to add a new rock or orb to your backpack and, potentially, get the chance to attend an event or obtain a game-changing artifact.

While the opening act of the game, set in a forest, feels like Peggle with RPG mechanics on top, that feeling doesn’t last. By the time you’ve prevailed past a castle and into the void, gravity and gameplay will both be significantly different. Mastered all the areas? You’ll still have the “cruciball” challenge, which tilts the odds against you, and new characters to play with as well. Plus, the developerss keep updates coming, both improving upon the game and adding new orbs to fight with. Peglin is a fully-contained offline adventure.

Peglin is free with in-app purchases.

5. Shattered Pixel Dungeon

If you want a traditional, adventure roguelike Android game, then Shattered Pixel Dungeon is worth your time. Ditching awkward numpad controls and step-by-step movement, Shattered Pixel Dungeon takes you on a finger-accessible journey with mobile sensibilities. Collecting items, discovering the unknown, and bashing enemies with swords and spells are all still there in all their traditional roguelike glory for you, though.

[Related: The best Android apps for your Chromebook]

You may already be familiar with part of the title of the game, and that’s because it comes as a fork, or separate branch, of the open-source code of Pixel Dungeon. While other forks of this game exist, Shattered Pixel Dungeon is generally favored above others for its consistent development, plethora of extra items and entities, and nearly 10 years of independent history. If you like this game, other Pixel Dungeon variants may also be worth a spin.

Shattered Pixel Dungeon is free to play.

While these games are meant to be best enjoyed on an Android phone, the fun doesn’t have to stop there. If you’d like to get them on a bigger screen, check out our guide on how to use Android games on PC.

Oceans are now one step closer to being battlefields for robotic ships. This past week the US Navy announced that its task force focused on developing autonomous technology and artificial intelligence for the service successfully fired several small missiles at empty boats in the Middle East as part of a test, hitting the targets each time. It was a major step in the Navy’s efforts to build uncrewed surface vessels (or USVs, as they are also called) that can be used for smaller combat situations.

The tests, dubbed Exercise Digital Talon, took what essentially looked like a small speed boat fitted with a weapons system in open international waters in the Arabian Peninsula on Oct. 23. The ship, called a MARTAC T38 Devil Ray USV, took its orders from a human operator who was on shore.

The Digital Talon tests were carried out by Task Force 59, a Navy group focused on building out USV capabilities and integrating them with crewed ships, in conjunction with Special Operations Forces Central Command.

“During Digital Talon, we took a significant step forward and advanced our capability to the ‘next level’ beyond just maritime domain awareness, which has been a traditional focus with Task Force 59,” Vice Admiral Brad Cooper, commander US Naval Forces Central Command (or NAVCENT), said in a statement. “We have proven these unmanned platforms can enhance fleet lethality.”

Watch the tests for yourself here.

The vessel used in the test was fitted with a small missile launching apparatus called a Lethal Miniature Aerial Missile System. The USV specifically fired a Switchblade 300 loitering munition, according to Switchblade maker AeroVironment. Loitering munitions function essentially like a drone with a camera, able to provide surveillance—but then operators have the option of having them hit a target like a missile. US special operations forces have increasingly used the Switchblade in recent years. Thanks to its versatility for surveillance and offense, the weapons were also sent to Ukraine as part of the American effort to arm Kyiv with an array of drones and powerful missile systems. The War Zone (which is owned by PopSci’s parent company, Recurrent Ventures) noted that the boat appears to have a Starlink satellite antenna module mounted on it.

This is not the first time the Navy has successfully fired a weapon from an uncrewed ship like this. In 2021, it successfully launched a SM-6 missile from the USV Ranger. That ship, essentially a repurposed supply vessel with advanced autonomous technology, let the Navy experiment with how automated systems and weapons platforms function when added to an existing vessel. 

The Digital Talon test marked the Navy’s first live-fire exercise with a USV in the Middle East, where the US military has increasingly deployed uncrewed surface vessels in recent years. Alongside testing the weapons systems themselves, Digital Talon was meant to examine the Navy’s capabilities for “manned-unmanned teaming.” And although the Switchblade munitions— while destructive—are much less powerful than the wider weapons capabilities of the Navy’s crewed vessels, the Digital Talon test is another benchmark in the Navy’s goal of building out its ghost fleet of USVs in the coming decades.

In fact, the Navy wants to deploy a lot of USVs in the next two decades. The Chief of Naval Operations Navigation Plan 2022, published in July 2022 by then-Chief of Naval Operations Admiral Mike Gilday, outlined a goal of essentially doubling the size of the current combat fleet by 2045, with 350 new crewed vessels by 2045 as well as 150 new vessels that are totally crewless. 

So far the US Navy has been steadily testing different models of USVs in the field. That ranges from smaller Saildrone Explorer USVs that the Navy uses to monitor Iranian maritime activities in the Strait of Hormuz, as well as having two USVs, including the USV Ranger, participate in the 2022 addition of a multinational exercise called the Rim of the Pacific. Although technically uncrewed, many of these USVs can also have Navy personnel onboard, for monitoring and manual control should the need arise. 

Uncrewed surface and submersible vessels have already been used as lethal and effective weapons. In the Middle East, Houthi militants have used USVs against Saudi Arabian forces, where the Saudi’s military capabilities and equipment far outclass the Yemeni rebels. In the war in Ukraine, Ukrainian forces have used these ships as part of joint aerial and maritime drone swarm attacks on Russian military ships.

The Digital Talon test also comes as the United States has increased its military presence in the Middle East over the past several months. That started in the spring and summer, in response to incidents in the Strait of Hormuz. The US military sent warships, a Marine Expeditionary Unit, and an array of additional aircraft to the region.

This past month, in response to the Oct. 7 attacks on Israel and the Israeli war with Hamas, the US has sent additional troops and aircraft, as well as deployed two carrier strike groups to the region. In the Navy’s statement on the Digital Talon tests, Vice Admiral Cooper added that the successful exercise is helping the Navy with “strengthening regional maritime security and enhancing deterrence against malign activity.”

The Navy’s 2045 vision imagines a number of uncrewed or skeleton-crewed large ships in the fleet, such as the Large Unmanned Surface Vehicles. But smaller USVs like the one used for Digital Talon are important in other ways. These small vessels fitted with loitering munitions could essentially serve as a protective force for larger ships, intercepting boats and USVs armed with explosives for attacks on those vessels. As a war game in 2002 showed, the low-tech tactic of simply sending large waves of tiny vessels toward larger ships can be devastatingly effective. In that game, Marine Corps Lt. Gen. Paul Van Riper, commanding the exercise’s adversarial “red team,” was able to quickly take out the more high-tech and advanced “blue team” vessels with such an attack. 

The Digital Talon test was just that—a test. It’s still unclear if the fleet proposal for 2045 that Gilday laid out will become a reality, as many of those ships would need to be financed and constructed. But last month’s test showed the very real weapons capabilities the Navy’s USVs have now, and could presumably be expanded to other ships in the current fleet.

To put it very simply: the Rimac Nevera electric hypercar is very, very fast. With 1,194-horsepower, a top speed of 256 MPH, and the ability to accelerate faster than an F1 racer, it’s not just one of the most powerful EVs in the world—it’s one of the most powerful cars, period. The $2.1 million Nevera has dashed past so many world records at this point that its makers are now forced to get creative in setting new ones. And they certainly have, judging from a new video released on November 7.

In addition to all its other feats, the Rimac Nevera is apparently now also the Guinness World Record holder for the “fastest speed in reverse.” How fast did it take to earn yet another laurel? 171.34 MPH—certainly an intense speed in any direction.

[Related: Behind the wheel of the bruisingly quick Rimac Nevera hypercar.]

On Tuesday, Nevera chief program engineer Matija Renić revealed that the new stunt actually began as a joke during the hypercar’s development stage.

“We kind of laughed it off,” Renić said via the company’s announcement. Renić noted its cooling and stability systems, not to mention aerodynamics, simply weren’t engineered for putting the pedal to the floor while in reverse. “But then, we started to talk about how fun it would be to give it a shot.”

Simulations indicated a Nevera likely would top 150 MPH while driven backwards, but there was no way to be sure just how stable it would remain while blazing down the road. “We were entering uncharted territory,” Renić added—an understatement if there ever was one.

But as these multiple videos attest, the Nevera is certainly up to the task should it ever improbably become necessary. According to the company’s record-setting test driver, pulling off the stunt “definitely took some getting used to.”

“You’re facing straight out backwards watching the scenery flash away from you faster and faster, feeling your neck pulled forwards in almost the same sensation you would normally get under heavy braking,” Goran Drndak said via Rimac’s November 7 announcement. “You’re moving the steering wheel so gently, careful not to upset the balance, watching for your course and your braking point out the rear-view mirror, all the while keeping an eye on the speed.” Although being “almost completely unnatural” to the car’s design, Drndak said the Nevera “breezed” through the stress test.

It’s hard to imagine what’s left for the Nevera to achieve, but if the latest record is any indication, chances are Rimac designers will think of something.

Bees are extremely adept at communicating, even though their brains weigh just two milligrams. They’re so efficient at reaching a consensus, in fact, that researchers created a mini-robot team inspired by their ‘conversations.’

In the search for a new nesting spot, scout bees are known to conduct tiny “waggle dances” to indicate their preferred hive location—slowly winning over swarmmates to join in the process. The moves are tiny but complex, involving moving in figure-eight patterns while shaking their bodies at rapid speed. The bees with the most popular dance part earn final say on where to build. While the three centimeter-wide “kilobots” under the watch of a team at Spain’s University of Barcelona can’t shimmy and shake just yet, they do signal to one another much like bees.

[Related: Bee brains could teach robots to make split-second decisions.]

As detailed in their preprint paper submitted in late October, the team first attached a colored LED light alongside an infrared-light receiver and emitter atop each of a total of 35 kilobots. They then programmed the bots using a modified version of a previously designed mathematical model based on scout bee behavior. From there, the team placed varying numbers of kilobots within an enclosure and let them jitter through their new environment on their trio of toothpick-like legs. During over 70 tests, researchers ordered certain bot clusters to advertise their preferred nesting location “opinion” via signaling between their LED lights’ red, blue, and green hues.

Every kilobot team achieved a group consensus within roughly 30 minutes, no matter the team size or environmental density. Such reliable decision making—even in machines capable of transmitting just 9 bytes of information at a time—could one day prove invaluable across a number of industries.

[Related: Bat-like echolocation could help these robots find lost people.]

“We believe that in the near future there are going to be simple robots that will do jobs that we don’t want to do, and it will be very important that they make decisions in a decentralized, autonomous manner,” Carmen Miguel, one of the study’s co-authors, explained to New Scientist on November 7.

During invasive medical procedures, for instance, tiny robots could maneuver within a patient’s body, communicating with one another without the need for complex electronics. Similarly, cheap bots could coordinate with one another while deployed during search-and-rescue missions. In such scenarios, the environmental dangers often prevent the use of expensive robots due to risk of damage or destruction.

Above it all, however, the University of Barcelona team believes their work draws attention to often underappreciated aspects of everyday existence. The team’s paper abstract concludes: “By shedding light on this crucial layer of complexity… we emphasize the significance of factors typically overlooked but essential to living systems and life itself.”

The Android versus iPhone debate continues to rumble on. But one thing is certain: Google’s phone software is still more versatile and customizable than Apple’s offering. Dig into the settings and discover Android’s secret capabilities, including a host of hidden features and useful tools. We’ve collected 12 of them here.

A quick note before we begin: Android has a wide variety of makes, models, and versions, which makes it difficult to find features that will be consistent across all devices. We only verified the following tips on stock Android 14—they should also work on related systems, but some of the menus and procedures may vary slightly.

1. Enable flash notifications for silent updates

Loud notifications are annoying, but have you ever heard a phone vibrating on a glass table? Somehow, it’s even worse. So whether you want to stay up to date with your texts in a quieter way or you’re hard of hearing, Android now allows you to set flash notifications, where your phone’s screen or built-in flash will blink to let you know there’s something new requiring your attention. 

To set it up, go to Settings, Accessibility, and Flash notifications. You’ll get two options: toggle the switch next to Camera flash to have the light on the back of your phone flash three times when you get a notification; or toggle the switch next Screen flash so that your device lets you know of any new messages by flashing a yellow overlay on your screen. You can enable either or both of them to get an even more effective visual alert. 

To see how they work, make your preferences and hit Preview. 

2. Run apps side-by-side

This feature has been around since Android 7.0 Nougat, but it’s one of the few users tend to forget about. This side-by-side or top-and-bottom app view (depending on the orientation of your screen) comes in handy when you want to display photos, optimize your social networking, or multitask.

To set it up, make sure both apps you want to see are already open. Then, open the app carousel by doing a short swipe-up gesture from the bottom of your screen. Find the recent app you want to use and press on the circular icon at the top of its preview. On the emerging menu, you should see a Split top option. Keep in mind that not all apps support this feature (like Instagram, for example), so if you don’t see this option, it’s because you can’t use it like this. If you see it, tap Split top, and the app will automatically position itself at the top or left of your screen. On the other side, you’ll see the app carousel, from where you can open a second app. This time, just swipe your way to it and tap on the preview to open it.

You’ll notice a thick black line separating both apps—from the middle drag it up or down to re-distribute your screen. To exit Split Screen mode, just drag the black line all the way up or down.

3. Lock phone borrowers inside one app

This is one of those Android tricks you need to know if you find yourself constantly lending your phone to a friend or young family member. Because if you do, you probably know that sudden anxiety that comes with the possibility of them going through your private information or posting to your social media accounts. 

App pinning lets you be generous without giving up your privacy and will lock one app to the screen until someone unlocks your device. Essentially, the user won’t be able to access any other parts of your phone without your credentials.

[Related: How to safely share your phone with others]

Screen pinning is easy to set up. Open Settings, go to the Security & privacy menu, scroll down to choose More security settings, and tap App pinning. Once you’ve turned on the feature, launch the app your friend needs to use and open the app carousel by making a short upward swipe from the bottom of the screen. Swipe your way to the app you want to pin and tap on the circular icon at the top of the preview. On the emerging menu, tap Pin. To unpin the app, swipe from the bottom of your screen and hold. This will lock your phone and you’ll have to enter your pattern, password, PIN, or biometrics to use it.

4. Activate one-handed mode

As today’s phones continue to grow in size, they become harder and harder to operate one-handed. So Google’s custom keyboard, which is the default option on certain Android phones, has a solution: A special one-handed mode that you can switch to with a simple shortcut. If you own a Pixel phone, this keyboard will be your default typing option. If you’re on a Samsung or LG phone, you’ll have to first download Google’s version and set it as your default keyboard (as demonstrated in Tip 7).

Open up the keyboard as normal and tap and hold on the comma key. Drag up to the right-hand icon to enable one-handed mode. The arrow lets you switch this smaller keyboard from side to side, the bottom icon lets you reposition it, and the top icon restores the full-size keyboard. Other phone keyboards may also have one-handed modes, but they can be harder to access than Google’s. Try looking up your phone model and searching “one-handed keyboard” to learn more.

5. Customize your experience with regional preferences

If you live in a foreign country either permanently or temporarily, you might find it frustrating that all apps and services are built to work according to that area’s specifications—metric units, calendar settings, etc. Some apps allow you to change these settings one by one, but that takes a while and you’ll have to do it all over again if you change phones, for example. 

This is why Android 14 debuted Regional preferences, a menu where you can change these settings at a system level so you don’t have to dive deep into each individual app. Find this feature by going to Settings, System, and then Languages. Once you’re there, open Regional preferences—you’ll be able to pick temperature units, number preferences, and the first day of the week. These changes will apply wherever possible within your device.

6. Choose new default apps

One of the differences between Android and iOS is that Google’s mobile operating system lets you choose different default apps for web browsing, texting, viewing photos, etc. A default app is the one that opens automatically when you try to do something on your phone—so when you click a link, for example, your default web browser app will automatically open it.

Take advantage of this flexibility by setting up the defaults as you want them. Head to Settings, go to Apps and choose Default apps. Select any of the categories on screen to see a list of installed apps that can take over default duties. For example, if you’d prefer to chat with friends via Facebook Messenger, rather than your phone’s built-in SMS app, you can make Facebook’s product your default messaging app.

7. Cast your Android screen

For a number of years, you’ve been able to broadcast your Android phone or tablet’s display to the larger screen of a television using a Chromecast. In addition to beaming video from all the usual movie and TV apps, this streaming device can mirror your phone. Take advantage of a shortcut in the Quick Settings pane especially made for this feature, which you can access by dragging down from the top of the screen with two fingers. You should find a Screen Cast option in this menu. If it doesn’t show up, swipe left on the Quick Settings menu for more options, or tap the pencil icon at the bottom to add the shortcut.

[Related: How to put video calls on your TV]

There’s also another way to set up mirroring. First, check to make sure you’ve installed the Google Home app for Android—you probably already used this program to set up your Chromecast. Open the app and choose your Chromecast and your device’s display should appear on the big screen. On your phone, tap Media and choose from Music, Video, Podcasts, or Radio and select a service to start streaming.

8. Make text and images more visible

If you’re struggling to see what’s on the screen—or, alternatively, if you want to cram as much content as possible onto the display and don’t mind doing a bit of squinting along the way—you can zoom in or out on text and objects. Not all apps will respond to these adjustments, but most of them will.

To change size settings, open Settings and go to the Display heading. From there, tap the Display size and text and drag the slider under Font size to make text larger or smaller as needed. Android 13 introduced a new slider on this menu—Display size. You can play around with it to make icons and the Google search bar chunkier.

9. Disable the lock screen at home

To keep your device safe, you need to set up a PIN code or biometrics scan to unlock your phone. But this makes it more inconvenient to access your apps. Google’s Smart Lock feature lets you remove this obstacle, giving you instant access to your phone—but only when you’re safely at home.

From Settings, tap Security & privacy, go to More security settings and choose Smart Lock. As well as disabling the lock screen when you’re at home (that’s the Trusted Places option), you can also disable the screen when your phone’s Bluetooth is connected to a trusted device, such as your car stereo unit, or when it detects you have it on you.

10. Change volume settings independently

Your device plays several different types of audio—including ringtones, notifications, alarms, phone calls, and media. If you’ve ever gone to the Settings menu and opened Sound & vibration, you’ll have seen that you can use individual sliders to adjust these audio types individually.

However, Android gives you a quick-and-easy shortcut. Tap the physical volume buttons on the side of your device to make whatever’s currently playing quieter or louder (if no media is playing, this action will adjust your ringtone volume). When you do, a small box will pop up on the screen, showing which volume setting is changing and how. At the bottom of that box, you should see three dots. Tap them, and the box will expand to show multiple volume sliders at once. This can save you a trip to Settings.

11. Bring back lost notifications

So you accidentally swiped away one of the notifications that you wanted to read fully and now you have a nagging sense someone emailed you, but are not sure. It happens. If you want to review all of your recent notifications on Android, you’re in luck. This ability is possible—though the option isn’t easy to find.

[Related: Switching from iPhone to Android has never been easier]

Tap and hold on an empty part of the home screen, and a screen-adjusting mode will pop up. Choose Widgets, and find the Settings shortcut. Drag this icon to an empty space on one of your home screens, drop it in place, and a list will automatically pop up. Choose Notification log from the list and tap the icon to open up Android’s notification history.

12. Get an always-handy magnifying glass

Other than changing display options and making icons and text bigger, Android 14 introduced a new feature that lets you magnify specific parts of your screen. To enable it, go to Settings, Accessibility, and Magnification. Start by toggling on the switch next to Magnification shortcut, which will introduce a red magnifying glass button to the right of your screen.

Whenever you need a little help looking at text, pictures, or animations, you can summon the Magnification tool by tapping the red icon. An orange frame will appear on screen, zooming into the display portion underneath it (just like a magnifying glass), and you’ll be able to move it wherever you need it. If the default zoom is not enough, use your thumb and index fingers to expand the view even more. Tap the red icon again to disable the tool.

Today, Waze announced a new feature called crash history alerts that will warn drivers about upcoming accident black spots on their route. If you are approaching a crash-prone section of road, like a series of tight turns or a difficult merge, the Google-owned navigation app will show a warning so you can take extra care.

Waze has long allowed users to report live traffic information, like speed checks and crashes, as they use the app to navigate. This crowdsourced information is used to warn other users about upcoming hazards, and now will apparently also be used to identify crash-prone roads. According to Google, an AI will use these community reports combined with historical crash data and key route information, like “typical traffic levels, whether it’s a highway or local road, elevation, and more,” to assess the danger of your upcoming route. If it includes a dangerous section, it will tell you just before you reach it. 

So as to minimize distractions, Waze says it will limit the amount of alerts it shows to drivers. Presumably, if you are navigating a snowy mountain pass, it won’t send you an alert as you approach each and every corner. It seems the feature is designed to let you know when you’re approaching an unexpectedly dangerous bit of road, rather than blasting you with notifications every time you take a rural road in winter. 

[Related: Apple announces car crash detection and satellite SOS]

Similarly, Waze won’t show alerts on roads you travel frequently. The app apparently trusts that you know the hazardous sections of your commute already. 

Google claims this is all part of Waze’s aim of “helping every driver make smart decisions on the road,” and it is right that driving is one of the riskiest things many people do on a daily basis. According to a CDC report that Google cites in its announcement, road traffic accidents are the leading cause of death in the US for people between 1 and 54, and that almost 3,700 people are killed every day in crashes “involving cars, buses, motorcycles, bicycles, trucks, or pedestrians.” Road design as well as driving culture are both part of the problem.

[Related: Pete Buttigieg on how to improve the deadly track record of US drivers]

Waze isn’t the first company to think up such an idea. Many engineers have developed similar routing algorithms that suggest the safest drives possible based on past driving and accident data. 

While one small pop up obviously can’t save the 1.35 million people who die on the roads each year, it could certainly help some of them. Google is running other traffic AI-related projects outside of Waze, too. For example, one Google Maps project aims to use traffic flow data to figure out which intersections to direct drivers to, ideally reducing gridlock at busy intersections. If you’re driving somewhere unfamiliar, maybe give Waze a try. An extra warning to take care when you’re approaching a tricky section of road might be just what you need to stay safe on the road.

A billionaire-backed Silicon Valley company says it now owns enough land to move forward with the next phases in creating a high-tech, utopian “city of yesterday.” In a recent email to PopSci, California Forever CEO Jan Sramek says he hopes “residents [will] keep an open mind [and] hear what we have to say,” while promising “we’ll do the same in kind.”

The news marked a turning point in the secretive, years-long campaign costing over $800 million, alongside a recently dropped $510 million lawsuit against local landowners. According to the project’s website, the group intends to build a new, green smart municipality from scratch atop its 53,000 acres. But despite promising “novel methods of design, construction and governance,” the project’s details remain vague.

[Related: Silicon Valley’s wealthiest want to build their own city outside of San Francisco.]

Founded by Sramek, a 36-year-old former Goldman Sachs trader, California Forever has quietly bought up tens of thousands of acres northeast of San Francisco since at least 2018. Investors include prominent venture capitalists, LinkedIn’s co-founder, as well as Lauren Powell Jobs, billionaire philanthropist and wife of the late Steve Jobs.

After years spent flying under-the-radar, Flannery Associate’s parent company finally launched a public-facing website in September featuring conceptual renderings and CGI walkthroughs of an idyllic townscape. The official site’s FAQ section argues the stealth campaign was “the only way to avoid creating a rush of reckless short-term land speculation.”

In a separate statement provided to PopSci on Monday, a Flannery spokesperson relayed the company “does not anticipate making any additional purchases” once it finalizes the “few remaining properties” under contract in the coming weeks. It is unclear if the final properties under contract differ from those recently purchased from local Solano County farmers following the contentious legal battle. Flannery filed its $510 million lawsuit in May 2023 against a group of local landowners, citing antitrust violations.

Speaking with PopSci last week via email, Flannery’s spokesperson contended this “small group” of residents engaged in a “targeted campaign” of slander, but denied that the company was suing local farmers for simply refusing to sell. The spokesperson cited an alleged incident from July 2022, when a farmer offered his property to Flannery for $32,000 per acre—nearly 10 times “fair market value” at the time, claims Flannery. After company representatives refused to buy at that price point, the farmer allegedly engaged in a “secret conspiracy” alongside fellow landowners to agree upon a standard selling price “so [Flannery] cannot play owners against owners,” the spokesperson said.

“Flannery has been reasonable when settling the case with many of the defendants, and has been willing to negotiate generous settlements with the remaining defendants,” the spokesperson concluded last week. On November 3, Bloomberg Business revealed the lawsuit’s defendants have since agreed to sell their remaining land to Flannery Associates for $18,000 per acre.

Critics, however, continue to voice concerns over the project’s logistical, legal, and governmental vagaries. Earlier this year, Rep. John Garamendi (D-CA) argued to a local California news outlet that the area’s proximity to Travis Air Force Base meant “[foreign] spy operations or any other nefarious activity could take place” there. Rep. Garamendi added such issues “could detrimentally impact the [base’s] ability…  to operate in a moment of national emergency,” and criticized Flannery’s then-ongoing lawsuit against locals. PopSci has reached out to Rep. Garamendi’s office for comment, but did not receive a response at the time of writing.

“Travis Air Force Base is critical to both our national security and to Solano County. We fully support its mission and always will,” reads a portion of California Forever’s FAQ page.

In August, Solano County residents began receiving text and email opinion polls regarding a potential future ballot initiative. The messages at the time described an urban project including “a new city with tens of thousands of new homes, a large solar energy farm, orchards with over a million new trees, and over 10,000 acres of new parks and open space.” In an interview with local Bay Area news outlet ABC 7 in September, Sramek also said he envisions it to be “one of the most walkable places in California, probably in America” while possessing a “very traditional feeling to it.”

“The idea of building a new community and economic opportunity in eastern Solano seemed impossible on the surface,” Sramek wrote to PopSci last week. “But after spending a lot of time learning about the community, which I now call home, I became convinced that with thoughtful design, the right long-term patient investors, and strong partnerships… we can create a new community,” Sramek said at the time.

One of the new iPhone functionalities ushered in with the arrival of iOS 17—like offline Apple Maps support—is StandBy mode. This feature turns your iPhone into a small smart display that will show you everything from calendar appointments to your favorite photo albums.

Perhaps the obvious use of StandBy mode is to turn an iPhone into a bedside clock, displaying the current time and even dimming the display once the lights go out. But there are plenty of other ways to use it.

StandBy mode is available on iPhones running iOS 17—that’s the iPhone XR, iPhone XS, and iPhone XS Max launched in 2018, and every handset that’s appeared since.

If you have a Pro or Pro Max version of the iPhone 14 or 15, your device can display StandBy permanently on screen. On other models, you’ll need to wake the display to see it: You can do this by tapping the display or waving your hand in front of it.

How StandBy mode works

You can enable StandBy mode by going to StandBy on the Settings screen and turning on the StandBy toggle switch. If you’re using an iPhone with an always-on display, use the Always On toggle switch to determine whether StandBy mode stays permanently on the screen.

[Related: 6 great features to try out on iOS 17]

To have StandBy mode activate automatically, charge your iPhone and prop it up on its side and at an angle (so not flat on a surface). Once your device meets all of these conditions, StandBy mode turns on—the first time that happens you’ll see a message explaining what StandBy mode is. By default, you’ll see clock and calendar widgets appear first. To quit StandBy mode, simply pick up your phone, lay it down flat, or remove it from the charger.

The feature works with both wired and wireless charging, but MagSafe chargers have a bonus functionality: StandBy mode remembers how you’ve configured it on each separate charger, so you can have different setups for different rooms (the bedroom and the kitchen, for example).

Customizing StandBy mode

Swiping left or right on the StandBy mode screen cycles through the different views available to you. There’s a widgets screen, a photos screen, and a clock screen, and on each one you can swipe up and down for different configurations.

On the widgets screen, the display is split in two so you can swipe up and down on them separately to scroll through the available widgets. You can pick from the weather forecast, your upcoming calendar appointments, and any active reminders.

Long press on the widgets screen to remove add-ons from the list (via the minus button) or add new ones (via the plus button). The widgets you see will depend on the apps installed on your phone, but there are a bunch of native ones built into iOS to get you started.

Other than the widgets available to you, you’ll see other options similar to the ones you have for widgets on the home screen. Smart Rotate will intelligently change the available widgets based on the time of day and your usual habits, and Widget Suggestions will add in widgets based on the apps you already use a lot.

A long press also unlocks options on the photos screen, allowing you to choose a particular album in your gallery that’s different to the images StandBy mode chose for you.

A long press on the clock screen brings up the available options of that particular view, but as of yet, there’s no option to add a new clock face.

Back on the StandBy screen in iOS Settings, you can customize the StandBy feature in a few more ways. The Show Notifications toggle switch determines whether incoming notifications appear in StandBy mode—enable the Show Preview on Tap Only option underneath if you’d rather not have previews (like the first lines of messages) appear on screen.

[Related: Hand gesture reactions are one of macOS Sonoma’s coolest new features]

You can also tap Night Mode and enable the Night Mode toggle switch. This feature dims the display and turns everything on it red whenever your iPhone detects it’s in a dark environment. That way, StandBy doesn’t stop you from getting to sleep. The same screen has a Motion To Wake toggle switch: Keep it on if you want to be able to wake the screen with a wave, or turn it off if you find your nightly tossing and turning is constantly lighting up the display while you’re in bed.

A tiny glimmer spotted amid seagrass by a diver off the Italian coast has yielded one of the largest historical treasure troves in over a decade. According to a November 4 announcement by Italy’s culture ministry, an archeological recovery team has recovered somewhere between 30,000 and 50,000 near-pristine ancient coins from the Mediterranean Sea dating back to the fourth century Roman empire. 

[Related: These ‘fake’ ancient Roman coins might actually be real.]

Authorities described the large, bronze coins (known as follis) found near the town of Arzachena “in an exceptional and rare state of conservation,” with only four appearing slightly damaged. Upon further inspection, experts determined the currency originated across the Roman empire between 324 and 340 CE—roughly during Constantine the Great’s reign—with nearly every active mint known from the time, apart from Antioch, Alexandria, and Carthage.

Roman follis coinage entered circulation circa 294 CE during monetary reforms instituted by the emperor Diocletian. Even without a final official coin count, the Arzachena find is already confirmed to be larger than the last major follis discovery made a decade ago in the UK. In 2013, a local metal detector enthusiast uncovered 22,888 follis near Seaton Down a few hundred feet away from the site of a Roman military fort and villa circa the second-to-third centuries.

“The treasure found in the waters of Arzachena represents one of the most important discoveries of numismatic finds in recent years and highlights once again the richness and importance of the archaeological heritage that the depths of our seas… still guards and conserves,” Luigi La Rocca, regional director general of archaeology, fine arts and landscape, said via the Italian government’s recent announcement. La Rocca went on to describe such artifacts as “an extraordinary but also very fragile heritage” that is now constantly threatened by climate change and other human ecological impacts.

[Related: AI revealed the colorful first word of an ancient scroll torched by Mount Vesuvius.]

The tens of thousands of coins may not be the end of discoveries off the Sardianian coast, either. While recovering the follis, divers also found fragments of tall, two-handled, narrow neck jugs known as amphorae. Combined with the coins’ location across “two macro-areas of dispersion” in a large, sandy area between the beach and seabed, experts believe the region could hide the remains of a yet-to-be-uncovered shipwreck. Conservationists are now moving forward with follis restoration efforts.

In Sweden, the word lagom represents the Goldilocks-esque concept of “not too much, not too little, but just right.” Swedish automaker Volvo had this concept in mind when it created the brand’s newest model, the EX30. At the same time, the electric car had to meet a major objective: have the lowest carbon footprint of any Volvo model to date.

Volvo says that the EX30’s “total carbon footprint” is 25 percent less CO2 than the electrified versions of its C40 and XC40 models, in line with the automaker’s stated goal to cut CO2 emissions per car by 40 percent by 2025. To achieve this, they took into account the manufacturing processes, worked to simplify its design, and reduced the materials it needs. Even the exterior colors like Moss Yellow and Cloud Blue superficially reflect Volvo’s Earth-friendly goals. 

What’s more, the vehicle will cost less than $40,000, which in a world of extra-pricey EVs (the average price for an EV was $53,469 in July of this year, according to Cox Automotive), is impressive. Starting at $36,245 (including destination fees), the EX30 is an attractive package.

Here’s how Volvo achieved its sustainability goals while aiming for that “just right” feel.

Sustainable interior ‘rooms’ 

The company integrated recycled PVC collected from house window frames, PET plastic from single-use water bottles, plant materials like flax fibers, and even discarded denim threads from the blue jeans recycling process into the EX30’s interior. 

Buyers of the new EX30 can choose between four interior expressions for the vehicle. Volvo calls the interior themes “rooms” because people spend so much time in their car, Volvo color and materials designer Camille Audra explained to PopSci. 

Two interior rooms employ recycling themes: they are called indigo, which is made from denim like the blue jeans you may be wearing right now, and breeze, a patterned knit. And two feature natural materials: they are called mist (flax fiber) and pine (tree resin).

“This is inspired from fashion,” Audra says. “People wear blue jeans everywhere in the world.”

Old denim is often recycled into things like pet bed inserts, building insulation, and thermal packaging insulation.  During the process, Audra says, the short fibers that are left over could become waste, but in this case, are instead collected and woven into a new material.

Combined with cellulose (also a plant-based material) to give strength to the material, the fibers become a durable surface for the dashboard and door panels. Bonus: there are no zippers or button flies to get in the way. 

Along with blue jeans material, flax fiber is lightweight and natural. Also known as linseed, flax is exceedingly strong when woven into fibers. (The flowering plant yields seeds that are pressed to extract oil, or dried and sold as a product in grocery stores around the country. Flaxseed meal—the byproduct of the flaxseed oil-pressing process—has a second life as livestock feed.) Volvo is on track with other automakers, like Kia and Hyundai, that are also using flax fibers inside their cars for sustainability and weight benefits.

“We decided to use flax because it’s used to regenerate soil [between crops] and uses less water than other crops, and still has a nice touch and feel,” Audra says.

In the summer of 2021, Volvo revealed its Concept Recharge, which used flax fibers from a Swiss company called Bcomp. By investing in Bcomp, a company that has also provided products to the racing arm of McLaren or Porsche, Volvo now has a mainline to sustainable materials. 

“Bcomp’s calculations show that compared to regular plastic parts, the natural fiber-based composites are up to 50 percent lighter, use up to 70 percent less plastic and generate up to 62 per cent lower CO₂ emissions,” Volvo says. 

Volvo is also featuring a “room” in a pine theme. The manufacturer uses a material called Nordico, which is made from recycled materials such as PET bottles, corks recycled from the wine industry, and pine resin from sustainable forests in Sweden and Finland. 

New colors, natural themes

For one interior trim option, Audra revealed that the design team scanned a piece of granite and then imprinted the granite’s natural patterns onto the recycled plastic. Using a stone grain offers more recycling options later as well, because the texture doesn’t require paint as a finish. 

On the outside, Volvo offers a vibrant hue—probably the brightest color ever seen on a Volvo model—called Moss Yellow, inspired by the lichens that grow on the rocks of the west coast of Sweden. And Cloud Blue looks white in the sunlight but transforms into a soft blue when it’s overcast. 

Even the technology reflects Volvo’s all-in commitment to a low carbon footprint. By keeping parts to a minimum, Volvo creates fewer carbon emissions when manufacturing the EX30. So far, its strategy is working: the brand expects 80 percent of EX30 buyers to be new to Volvo, and overall sales are skyrocketing. 

Correction on Nov. 8, 2023: This post has been updated to clarify that the denim material is used on the dashboard and door panels, not the seats.

Arduino kits are great for teaching students about science, technology, engineering, and math. The Interaction Design Institute in Turin, Italy, created Arduino in 2005 to provide people of all ages with an easy, inexpensive way to build electronic devices and control them with rudimentary code. By making Arduino an open-source platform, the Institute made the technology freely available to anyone, which led to a vast array of starter kits. Today, everyone from young children to seasoned professional techies use them to build everything from simple devices that turn on the lights to robots controlled remotely via WiFi. Given their popularity, there are a lot of kits available. We look at some of the best Arduino kits and break down what you’ll find and how to choose one suited to your project and learning goals.

How we chose the best Arduino starter kits

Arduino kits have many similarities, so making our selection was not easy. Often, with our reviews, there are several key components to highlight, but Arduino starter kits have dozens, if not hundreds, of elements. In this case, it’s not a very practical approach. What we’ve done instead is ensure that a kit includes key elements, then focus on how each kit satisfies the needs of a particular learner. Does it suit a complete beginner? An intermediate user? Does it meet the criteria for STEM learning? By doing that, we believe we’ve provided a broad selection that offers something for just about everyone.

The best Arduino starter kits: Reviews & Recommendations

Most Arduino starter kits are very affordable. That said, we included a premium option for those enthusiastic makers who want to develop multiple projects without having to shop for more components. Not surprisingly, larger kits also tend to offer greater versatility. No matter what you’re looking for, we’ve got an option here for you.

Picking the best Arduino starter kit is no easy task, given the huge variety. That said, nobody has more expertise teaching beginners than the Arduino organization, and its official starter kit provides a wide-ranging yet easy-to-understand introduction to coding and electronics.

The Official Arduino Starter Kit is ideal for STEM learning or for adult hobbyists or professionals interested in these areas. It features the latest UNO R3 microcontroller board and more than 100 components. The array of switches, sensors, actuators, motors, and displays offers terrific versatility. The kit includes an excellent project guidebook. The Arduino software (called Integrated Development Environment, or IDE) isn’t supplied but is available as a free download.

Buyers pay a premium for the name, but the official Arduino starter kit is backed by an array of online resources that allow makers to expand their learning and undertake projects far beyond the 15 provided within this excellent kit.

Best beyond the basics: Sunfounder Mega2560 R3 Project Kit

SEE IT

Why it made the cut: Budget Arduino starter kits are great for introducing beginners to coding and electronics, but eager learners soon want more. The SunFounder kit provides the logical ‘next step’ and great value for money.

Specs

• Board: MEGA2560 R3
• Number of Components: 291
• Projects Included: 40

Pros

• MEGA2560 board offers increased versatility
• Online tutorials extend capabilities
• Convenient storage case

Cons

• Not ideal for beginners

Inexpensive entry-level Arduino kits provide a great way to start learning about coding and electronics. But their versatility is somewhat limited, and those eager to continue learning may soon want more. Fortunately, they don’t need to spend a great deal of money to extend their skill set. This SunFounder kit offers an extensive collection of components and is great value.

The kit is based on the MEGA2560 board, which is larger than the UNO and provides a wider range of connectivity options. That allows users to employ more complicated wiring. Used in conjunction with items like an ultrasonic ranging module, joystick and tilt switch, makers can build more complex mechanisms. Although the kit includes 40 projects, many more can be developed using online resources.

Users must download the IDE separately. While SunFounder provides some code, it, like instructions, is not as comprehensive as it might be. It’s less detailed than some competitors’, meaning learners may have to find solutions elsewhere or use other online resources to maximize the kit’s potential. While these challenges are not difficult to overcome, we would not recommend this kit for beginners.

Best WiFi set: GAR Monster Starter Kit for Arduino

SEE IT

Why it made the cut: It’s expensive, but the GAR Monster starter kit can help beginners build and control complex wireless systems.

Specs

• Board: MEGA2560, UNO R3, NANO, ESP32 WiFi & Bluetooth
• Number of Components: Over 500
• Projects Included: None (see description)

Pros

• One of the largest component collections available
• Includes three different microcontroller boards
• Wireless capabilities

Cons

• Expensive
• May be overwhelming for beginners

Goliath Automation and Robotics (GAR) claims its Monster starter kit for Arduino is second only to its $500 Colossus kit as the largest kit available.

While the Monster starter kit is not cheap, it is impressively comprehensive. Although it will definitely appeal to more advanced users, it includes basics like the UNO R3 board that make it suitable for beginners. As a maker’s skills and knowledge increase, the MEGA2560 board allows them to pursue more complex projects, and the NANO and ESP32 platforms make it possible to develop wireless systems. The GAR Monster starter kit is also compatible with Windows, macOS, Linux, Android, and Raspberry Pi.

The instructions are fairly basic, and the main repository for projects is online. GAR offers an expanding library, but that’s really just the start. Given the number and variety of components provided, those wishing to extend their knowledge will find literally hundreds of suitable projects on the internet.

Best budget: Elegoo UNO Project Basic Starter Kit

SEE IT

Why it made the cut: Elegoo makes a number of highly-rated Arduino starter kits. This one may be the most affordable one you’ll find, but it offers all the basics needed to get started.

Specs

• Board: UNO R3
• Number of Components: Over 100, though many are duplicates
• Projects Included: 8

Pros

• Remarkably low cost
• Good quality components
• IDE included on CD

Cons

• Breadboard (a plastic board used to prototype projects) is smaller than some expect
• Limited project scope

The Elegoo UNO Basic Starter Kit is designed for those who want to try Arduino without spending much money. It includes the UNO R3 microcontroller, a reasonable assortment of components, and a CD that contains a PDF tutorial and the IDE software.

The tutorials focus on introducing the concepts of using code to drive electronic devices. It is a valuable introduction for beginners. The tutorials are very informative, and produce real-world results like illuminating an LED, activating a buzzer, and other fun projects). That said, keen learners will soon seek more demanding challenges, and although they’ll find other projects online, the variety of components included in this kit may limit their ability to pursue them.

The kit offers a couple hundred components, but many of them are duplicates. For example, it includes five red LEDs, five green LEDs, etc. Although it includes 130 resistors, they are limited to 10 types. Every component has its use in basic projects, but this kit does not offer the versatility that might appear at first glance.

What to consider when buying an Arduino starter kit

Arduino is an open-source hardware and software platform, which means anyone can copy the designs to produce an Arduino starter kit. As a result, many are essentially clones of the original and are largely similar. That said, the quality and content of each kit can vary considerably. Here’s what to look for.

Boards

The core of every Arduino starter kit is a board that contains a microcontroller. This can interpret a signal (input) and perform an action (output) based on instructions supplied by the user. For example, pressing a button might turn on a light or move an object.

Arduino UNO, MEGA2560 and NANO are the most common boards, but many others are available. Each has its own specification, which will become of greater importance as a maker’s knowledge increases. Size may be a consideration if the goal is to build the board into, say, a robot or other confined space. UNO is the most basic and usually recommended for beginners. One of MEGA’s key features is the ability to accept more connections if the project’s wiring is complicated.

Projects/Tutorials

Most Arduino starter kits come with a number of projects or tutorials. These may be contained within a booklet or a DVD containing a PDF. Quantity varies from a single tutorial to the 40 projects included in our best value suggestion.

The creative possibilities of a particular kit usually exceed what is covered by the tutorials, however. Manufacturer’s websites, and those run by Arduino enthusiasts, provide almost limitless expansion and variation. Video tutorials are common. Note however that if they are not specific to a particular kit, buying additional components may be necessary.

Components

There are literally thousands of Arduino components and modules available. It’s certainly an area worth exploring. For beginners, it is undoubtedly easiest to buy a starter kit and follow the tutorials provided. A ‘breadboard’ is a key component, allowing circuits to be built without soldering.

While many Arduino components are available individually, there is a compelling argument for buying additional starter kits, even for those people who have gained some experience. This is especially true if a maker has a particular project or range of projects in mind. Larger starter kits frequently contain parts for related projects, and buying one can often be easier than compiling an extensive shopping list. They are convenient and may offer better value. Compatibility issues aren’t common—all components should follow the Arduino standard—but buying from the same manufacturer ensures everything works together.

Unauthorized harvesting of Americans’ personal online data isn’t just a privacy issue—it’s also a matter of national security, according to new findings. As highlighted in a recent study from Duke University researchers, bad actors can purchase current and former US military personnel’s sensitive information for as little as 12 cents a person.

At any given time, third-party brokers are collecting and selling millions of people’s personal data, often without their knowledge or consent. Much of this information is legally collected through public records, via embedded codes within websites and apps, or by purchasing other companies’ customer data. This is particularly an issue in the US, where federal laws governing the online data brokerage industry remain relatively permissible—creating huge revenue streams for companies like Meta, Google, and Amazon. Depending on whose hands the data troves fall into, the information can be used for everything from targeted advertising, to surveillance, to financial fraud.

[Related: How data brokers threaten your privacy.]

Disturbingly, researchers at Duke University’s Sanford School of Public Policy found US service members’ non-public, individually-identifying information such as credit scores, health data, marital status, children’s names, and religious practices—reportedly offered for sale through over 500 websites.

To test just how straightforward it can be to obtain the information, researchers first scraped hundreds of data broker sites for terms like “military” and “veteran.” They then contacted a number of these companies—some of which used .org and .asia domain names—via email, phone, Google Voice, and Zoom. The study authors eventually were able to purchase the personal data of almost 50,000 service members, and data about veterans, for barely $10,000. The team also noted that, in some instances, individuals’ current location data was available to purchase, although the authors did not do that.

Many brokers required little-to-no verification or proof of identity information before selling their sensitive data caches. In one instance, a company told researchers they needed to confirm their identity before purchasing military data via a credit card, unless the Duke University team opted to pay through a wire transfer—which they then did.

[Related: Your car could be capturing data on your sex life.]

This “highly unregulated” ecosystem is ripe for exploitation, write the study authors, and could be used by “foreign and malicious actors to target active-duty military personnel, veterans, and their families and acquaintances for profiling, blackmail, targeting with information campaigns, and more.” As NBC News also notes, foreign actors could use such data to identify and approach individuals for access to state secrets via blackmail, coercion, or bribery.

Like many tech industry critics, privacy advocates, and bipartisan politicians before them, the study’s authors stressed the need for comprehensive US data privacy oversight featuring “strong controls on the data brokerage ecosystem.” A handful of states, including California and Massachusetts, have passed or are considering individual data regulatory legislation, but a US federal law remains elusive. Researchers reference the American Data Privacy and Protection Act as a potential roadmap; Congress proposed the bill in 2022, but has yet to reintroduce it this session.

The study also cites the European Union’s General Data Protection Regulations (GDPR) as another example of a strenuous, comprehensive approach to protecting online privacy. Passed in 2016 and enforced in 2018, the GDPR guards against many of the digital security problems faced by US residents.

Harvesting American data isn’t just a third-party broker issue, however. According to a partially declassified 2022 report released earlier this year by the Office of the Director of National Intelligence, agencies including the CIA, FBI, and NSA consistently purchase citizens’ commercially available information from data brokers with little regulation or oversight.

Tired of paying increasingly hefty monthly subscription fees for your streaming services, only to scroll nearly as long as a movie’s runtime just to find something to watch? Well, your choices are only going to expand thanks to NASA’s new streaming channel. But at least when NASA+ launches on November 8, it won’t come with any fees or commercials.

The commercial free on-demand platform will be available via the NASA App on iOS and Android devices, web browsers, as well as through Roku, Apple TV, and Fire TV. The ever-expanding catalog will include live coverage of launch events and missions, original videos, and multiple new series.

“We’re putting space on demand and at your fingertips with NASA’s new streaming platform,” Marc Etkind, NASA Headquarters’ Office of Communications associate administrator, said earlier this year. “Transforming our digital presence will help us better tell the stories of how NASA explores the unknown in air and space, inspires through discovery, and innovates for the benefit of humanity.”

Check out trailers for some of the first series to hit NASA+ this month:

NASA Explorers will offer viewers a multi-episode look at the agency’s recently concluded, seven-year OSIRIS-REx mission. Completed in September, OSIRIS-REx successfully returned samples collected in space from Bennu, a 4.5 billion-year-old asteroid traveling across the cosmos since the dawn of the solar system.

Other Worlds will focus on the latest updates and news from the James Webb Space Telescope (JWST) program. Launched in 2021 following a 17-year-long development on Earth followed by a six-month orbital tune up, the JWST provides researchers with some of the most spectacular glimpses of space ever achieved. Over the course of its decade-long lifespan, the JWST aims to capture information and imagery from over 13.5 billion years ago—when some of the universe’s earliest galaxies and stars began to form.

And for those looking to just bask in cosmic majesty, Space Out will allow viewers to do just that alongside “relaxing music and ultra-high-definition visuals of the cosmos, from the surface of Mars to a Uranian sunset.”

“From exoplanet research to better understanding Earth’s climate and the influence of the Sun on our planet along with exploration of the solar system, our new science and flagship websites, as well as forthcoming NASA+ videos, showcases our discovery programs in an interdisciplinary and crosscutting way, ultimately building stronger connections with our visitors and viewers,” Nicky Fox, associate administrator of NASA Headquarters’ Science Mission Directorate, said over the summer.

NASA+ comes as the space agency nears a scheduled 2025 return to the lunar surface as part of its ongoing Artemis program. When humans touch down on the moon for the first time in over 50 years, they apparently will do so in style, with both Prada-designed spacesuits and high-tech lunar cameras.

Money transfer apps are incredibly useful, which is why they’re so ubiquitous. But Venmo, one of the most popular of the bunch, has a problem: by adding a social element to our spending, the platform makes all transactions public by default. 

This means that all of the internet (or, best-case scenario, your friends and their friends) knows you’ve been ordering pizzaPeruvian food for breakfast at least twice a week. Or that you bought a statue of questionable taste from some person on Facebook Marketplace. Or something beyond what we can put to print. Venmo keeps some things private, but certainly discloses enough information to let other people know who you’re spending with, and potentially on what, so finding out your friends went for brunch without you is only a matter of scrolling.

This is why you should make your Venmo private right now. Thankfully, accessing and changing the platform’s settings is easy. 

How to change your privacy settings on Venmo

1. Open Venmo and tap your profile picture in the bottom right corner of your screen. 

2. Tap the cog icon in the top right corner to open the settings menu. 

3. Go to Privacy. 

4. Under Default privacy settings, make sure you select the bubble next to Private. This will make sure transactions are only visible to you and the person who’s paying or receiving money from you. 

[Related: The 7 best apps for sending money]

There’s also a Friends option, which will make your activity visible to your friends and their friends, but we’d discourage you from going that way. Venmo is an extremely practical app people usually only use to transfer money, which is why we don’t usually think too much about who we befriend on there. Think about that one time you went out for drinks with a large group of people and one person picked up the check so everyone paid them instead. You may not even know that person well, but if they’re your friend on Venmo, they, along with all of their friends, can see how you spend your money. 

If you’ve been using Venmo for a while, you should know that changing your privacy settings doesn’t work retroactively, and will only keep your future transactions private. To protect everything from the past, tap Past transactions on the privacy menu and select Change all to private. 

To go even further, and since you’re already in the privacy menu, tap Friends list and set it to private. This will prevent people from knowing who you’re friends with on the app. To finish, toggle off the switch next to Appear on other users’ friends lists. This will ensure that, even if your friends can’t be bothered with their privacy settings, at least you won’t show up on their lists.

More Venmo privacy tips

Maybe you like the social element of Venmo and prefer to keep things between friends (and their friends). That doesn’t mean you can’t still take care of your privacy. 

Make individual transactions private

You should know that you can always make individual transactions private. This is easy to do but not very intuitive, so you might’ve missed it. 

After completing a payment, open the transfer on your timeline or profile. Under Transaction details and to the right of the date and time, you’ll see the transaction’s privacy settings in blue—tap it to change it. You’ll get the same options as on the app’s privacy menu, and you’ll be able to make your activity visible only to you and the other person, your friends and their friends, or the entire world wide web. 

Opt for nondescript descriptions

As we mentioned before, Venmo doesn’t disclose the amounts of money you transfer on the app, but it says who you’re paying, and who you’re friends with, if applicable. 

That’s a lot of information as it is, but most importantly, the platform shows everyone the description of each interaction, which usually gives away the nature of the transaction and the context. So, for example, if you see someone paying somebody else and posting a pizza or drinks emoji, you can easily assume they ate or drank together, which can easily fuel gossip or, in the worst cases, “conspiranoia.” 

[Related: It’s time to start paying for everything with your phone]

If you’re keeping things between friends, give your transactions a non-obvious description. Since this is a required field to finalize payments, you can type gibberish or anything else that doesn’t give away what the payment or request was for. If you think you might need a receipt in the future, text that person directly confirming tha transaction. 

Check your friends list often

When you search someone on Venmo or scan their account QR code, the app will immediately take you to their profile page. You’ll be able to see their picture and their name, but you’ll also be able to spot somewhat of a dark pattern—it’s easier to add them as friends than it is to just make or request a payment. 

This is because the Add friend button is immediately below a person’s account details, whereas the transfer button (a white coin and a pencil against a blue background) is all the way down in the bottom right corner of your screen. You probably know this, but you can easily miss it, especially in the “We gotta pay and go” mindset after a meal. 

Again, if you set your privacy settings to Friends, make sure you take a moment, maybe once every few months, to revise your friends list. Make sure you know everybody on there and delete anyone you might not interact with on the app again. That way you’ll have a good idea of who your audience is and keep some control over it.

Studying the ocean is a daunting task. It requires machines that don’t corrode in the seawater, and are able to withstand the escalating, crushing pressures as they dive down. While robots have become better at surviving these challenging environments since they became part of the crew embarking on deep-sea explorations, animals like elephant seals and weddell seals do it naturally with ease. As a workaround to keep the tech expenses low but the science quality high, a group of researchers had the idea to attach trackers and basic measurement tools detecting temperature, salinity, and depth to these seals to learn more about their massive marine habitat. 

The tracker looks like a funny little hat, but don’t let its appearance fool you. It has proven to be conducive to serious science. 

Earlier this summer, the team of international scientists working on the Australian Centre for Excellence in Antarctic Science (ACEAS) project published a report in the journal Communications Earth and Environment in which the seal divers wearing these satellite-paired, glued-on trackers revealed that the bottom of the sea in some areas is deeper than what’s stated on current maps. The seals also helped uncover a hidden underwater canyon in Antarctica’s seas that was then confirmed with other tools, Scientific American recently reported. 

This study is just one of the many planned projects for these blubbery, flippered research assistants. According to ABC Australia, the tracker-adorning seals are part of a 20-year project to understand the grooves and depths of the East Antarctic continental shelf and the seafloor below it. Turning the seals into effective free-roaming sensors can fill in gaps in data related to some of the most hard-to-get-to parts of the Antarctic ocean, as the seals are “tweeting” small packets of information they’ve collected to a satellite every time they surface. 

[Related: Tagging along with sharks to the ocean’s twilight zone]

Seals may know secret spots, too, that humans have never ventured to before, and they’re still actively exploring, diving down to the seafloor to forage, even when blankets of ice prevent ships and other human devices from accessing certain regions of Antarctica.  

This science is happening for an important reason. Getting a more accurate picture of the labyrinthic world under Antarctic ice is key to making predictions about how and how fast melting occurs as a result of climate change. The seals are definitely not the only tool scientists are deploying. Submersible robots like Boaty McBoatface and Icefin are also on a similar mission. 

There are many lacunas in the reams of scientific data regarding how the ocean is structured, and how its inhabitants traverse it. Part of the shortcoming is because researchers are approaching the task from a human perspective, and not seeing the environment the way an animal living there would. This could be why there are so many remaining mysteries around phenomena like, for example, where eels reproduce. Using an inside source, or an inside marine animal so to speak, may not be the worst idea to spy on their world. 

The method is already yielding results. Other than the seals, a team of scientists from Woods Hole Oceanographic Institution have tagged sharks to study the quirks of the ocean’s twilight zone, and another team tagged turtles in the Indian Ocean to gather data that could be used to predict cyclones.

As far as I can make out, the term “doomscrolling” started making the rounds in 2019, and became, for obvious reasons, far more infectious in 2020. We’ve had two more years of pandemic, and a yearish of whatever this next thing we are in is, and the term does not seem to be losing much luster. I still hear and use it, partly because, unlike many hashtag terms, it refers to an actual practice, or mode of behavior, or mind-wrecking compulsion, in which guise it remains a significant feature of many people’s lives, including my own.

I suspect you know it well: Whether over breakfast or on the metro or during a procrastination break at work, you dip into your newsfeed, which is largely distressing of course, but you keep at it, heading deeper into the gloom. You might start out with some of that old-school newspaper-reader attitude, a mix of curiosity and responsibility and self-concern, under which lies a more basic and unspoken mimetic impulse to keep up with the pressing narratives of a group, a region, a nation, a species. But then the bottom drops out, and the feed starts to feed on you. The number, scale, and wickedness of the problems served up by crisis media—wicked not only in the sense of being nasty and often nefarious, but of being hairy beyond all possible resolve, and therefore ripe for dissension—rears up like, well, a wicked monster, consuming hope, potential, and whatever modicum of feel-good you started your sesh with. And if you are additionally gobbling up spicy social media takes on said problems—something that is not habitual for me—well, my heart goes out to you.

We never begin the day doomscrolling. We are reading or researching, and then doomscrolling takes over, an uncanny transition from worried and even obsessive concern to hopeless dread and apocalyptic nausea. It’s that moment when, rather than turn from the proximate source of your stress—maybe switch to a novel or find your eternal center of timeless awareness or call your mom—you neurotically and addictively cling to the invading infoswarm of present and likely horrors, chain-smoking the grim tidings like they were butts picked from the gutter. What was once news of the world, consumed with the thoughtful if sometimes enraged concern of the citizen, metamorphs into one of those classic psychoanalytic objects of ambivalence: an amorphous and sickly nightmare Thing that simultaneously fascinates, compels, disgusts, frightens, and destroys. The more you try and get to the bottom of it, the more it sucks you under.

You might have noticed my charged language here—wicked, monster, horrors, nightmare—but all of it pales to the noun honored in the neologism that started us off: doom. Or rather, DOOM. It’s not exactly an everyday word. People sometimes casually drop the adjective—a doomed attempt, doomed from the start—but the noun is much rarer, at least outside of Marvel supervillains, or heavy metal, or old-school first-person shooters—in other words, outside the shadowy margins of genre. But this connection to dark fantasy, horror, and religious myth is, I would argue, absolutely key to the stickiness of the doomscrolling tag and, more importantly, to our susceptibility to the practice it names.

Compulsion is key to doomscrolling, which means that, whatever else is going on, we enjoy it. I suspect everyone has their own twist on this enjoyment, which has less to do with simple pleasure than with jouissance, the Lacanian idea of pleasure confused with pain or intensity, memorably defined in Seminar XVII as the tickle that ends “in a blaze of petrol.” What I want to do here is to approach that pleasure through the lens of genre and narrative. In this sense, doomscrolling—in contrast to “getting depressed by the news”—names a mythic or phantasmic supplement to our data-driven distress, a gothic dystopian nightmare excess drawn from the inky well of Story that stains and weirdly sweetens both our news and the way we digest it.

But it’s not just any over-the-top gothic dystopian nightmare excess. It’s DOOM, a word heavier than fate, more horrible than disaster, more gnarly and heathen than apocalypse. Just listen to some doom metal. Etymologically and otherwise, doom is not just a bummer but a last judgment—a final determination, a binding decree, a closing verdict that actively condemns, or reveals, the state of things. Doom is not just rendered—it is written or announced, and therefore read or heard in advance. The titular threat in Lovecraft’s Dunsanyesque tale “The Doom that Came to Sarnath” is actually the word DOOM itself, inscribed on an altar by a dying priest who foreordains, or perhaps only prophesies, the eventual destruction of the city.

That doom is frequently inscribed, reminding us of another dread resonance lurking in our neologism. For what is a doom written on if not a scroll? As a verb, digital “scrolling” is not quite a skeuomorph, but something close: the resurrection of an anachronistic media practice inside a contemporary one. But it’s the noun that holds the prophetic gravitas here. The Revelation of Saint John is awash with scrolls, including the famous one with seven seals, which unleashes the end-times brigade. The cosmos itself becomes a scroll in the book’s sixth chapter, with the sky receding “as a scroll when it is rolled up, and every mountain and island was moved out of its place.” Still later, an angel brings John a “little scroll”—with 5G hopefully—that he is commanded to eat—that is, to consume. He tells us it tastes sweet at first, and then sickens him with bitterness. Another blaze of petrol.

Doom does not always imply a cosmic barrister or prophet; sometimes the laws of physics are enough to foreordain an implacable fate. Doom is spoken, but doom also comes down, a thing of gravity we see heading toward us miles away, like the unavoidable death of our sun. So while you could just as easily call doomscrolling something like dreadscrolling, which better describes the actual feeling, doom names three additional features beyond dread: foreknowledge, finality, and inevitability. Whether it be the sentence of a pitiless cosmic barrister or the workings of karma, just deserts are on their way.

Most of us do not believe we are doomed most of the time. Even if we consider the enormity of the problems unfolding across the globe, we often hold to the idea that “we” are at fault, or possibly “they.” This means there is still something we can do about it. Even in the case of climate crisis—where a myriad of ships have long ago set sail, and the chickens coming home to roost are barbed and ferocious—the complex causes and dynamics at play get reduced in our imagination to human responsibility, and particularly to behaviors that can still be changed. Even if we blame corporations or globalist cabals, powers far beyond our meager levers, we still do not let humans off the hook. Choices and actions are still on the table.

In this situation, doomscrolling becomes a kind of edge-play with agency itself, both personal and collective. By feasting on more and more terrible news, we unravel whatever threadbare hopes remain, tipping ourselves into the ever-present abyss of hopelessness and fatalistic despair. But here’s the secret: Because so many of us feel guilty, painfully aware of our complicity in the trainwreck, doomscrolling’s descent into abject surrender offers its own hidden relief. We may remain fascinated with the intricacies of the car crash, but there is really nothing we can do about it. In our darker (or more realistic) hours, we may reason our way to such hopelessness—pessimism of the intellect, and all that—but the emotional submission is where the real frisson lies, the horror and, to be frank, the temporary release, or the sadomasochistic fantasy of release.

But who is the top in this scenario? Within the fantasy that drives doomscrolling, we may imagine that we are finally submitting to Reality, to the hard fact of a world collapsing like dominoes. But we are really bending down before our feeds. In this game, media is the Master.

On one level this is just stating the obvious. We all know that, left or right, “the media” gain from our dread and anxiety, that fear sells, that YouTube algos suck us into feverish extremes, that infinite scroll opens up what Hegel called “bad infinity.” But there is something deeper afoot, something about the mediation offered by narrative itself, or, more accurately, the intensification of narrative affect, the tendency of our storytelling to drift toward sensation.

As I rabbit-holed into doomscrolling, I stumbled upon a 2018 Futurity.org piece about a study in Risk Analysis that analyzed “the impact of dread on the social amplification of threat.” The study tracked the evolution of negative news stories as they passed through a chain of social media participants who did not have access to the original report. Over and over, this online game of telephone intensified the threat and thickened the telling with panic. Moreover, in the face of this “contagion of fear,” the re-injection of the original, less extreme data had virtually no effect on reducing people’s anxiety.

As I wrote above, we ramp stuff up because on some level we enjoy this s—. In the narratives we tell about the world around us, we get very excited about scenarios that are turbo-charged with onrushing threat. In other words, the dark compulsion that drives doomscrolling is partly a mode of our own imagination, but an imagination driven towards certain intensities. Sensationalism is built on sensation after all. Thrills and spills, Romanticism’s swoon of despair, the confrontation with the abyss or God’s plan. But now the possibility of all these feelies is stitched into the Real.

In that sense, doomscrolling is a way of “weirding” crisis media in order to secretly, unconsciously transform it into a subgenre of horror—a subgenre whose emotional effectiveness requires that we disavow the fantasies that partly drive it, a disavowal we effect by insisting on the reality of the data and the rationality of the fear and hopelessness it engenders. “I’m not indulging in fear, I am facing reality.” Note of course, that this dalliance with the Real has been part of horror’s game all along, from Kenneth Grant’s left-hand Lovecraft to heavy metal evil (“are they really Satanists?”) to “based on a true story” potboilers to “The Blair Witch Project” to creepypasta and Slender Man. The devil’s greatest trick is to convince us that he does not exist, but horror’s greatest trick is to convince us that its fabulations do.

Let me be clear: I am not saying that our narratives of existential threat, or social media signs of social collapse, are simply fictions. That would be stupid and insane. When we doomscroll, most of us (at least among the “us” likely to read this) are still participating in the lingering Enlightenment commitment to argument, evidence, clarity, and can-do agency, the rickety matrix that undergirds public discourse and the whole idea of “news.” We are absorbing more or less accurate information about the concrete material and historical conditions of the contemporary world — although those conditions now centrally include ferociously mediated narrative conflict that actively invokes and deploys all manner of fictions, phantasms, and genre plots.

The point about doomscrolling, though, is that the quality of the information doesn’t matter. Sooner or later, as we feed on our feed, even the most clear-eyed and rational among us slips gears, a psychomagical ka-chunk that resounds like an ancient hammer blow or a crypt door in a vampire flick: BOOM. DOOM. At that moment, we are thrust beyond the Enlightenment’s circle of illumination, facing an inner dread and an outer darkness that only myth or religion or cosmic horror can limn. And we got there not by closing our eyes to the deepening fractures in the world, but in seeing those cracks with more and more detail until a kind of vertigo seizes hold. As we tune into the little abysses now gouging the concrete world—in ecological systems, AI regulation, supply chains, mental health, political processes—those little abysses start to stare back. As I wrote long ago in Techgnosis, it’s not the sleep of reason that breeds our monsters, but reason with its eyes agog.

Do not mistake any of this as a counsel of despair. Doomscrolling is a reminder, again to allude to my first book, that our everyday factual lives are woven into an uncanny and psychopathological tapestry of myth, narrative magic, and the mysticism of ultimate things—ultimate ends, ultimate voids, death writ large. But it’s also true that the emotional poverty and insufficiency of social media and newsfeeds is revealed with stark abyssal clarity, and so equally clarifies the need to turn around and claw our way back to the world, to some sense of duration and depth. Reason and investigation are part of that process, but so too is a wiser engagement with our shadow selves. And one way to do that is to recognize and take responsibility for the stories and “affective intensities” swallowing us up.

What fiction is riding you? In Jung’s terms, those spelunking the deep self need to be wary of being “captured by the archetype,” a capture that is signaled everywhere these days by the “passionate intensity” evidenced in so many mediated voices, an intensity William Butler Yeats pegged a century ago in “The Second Coming” as a particularly terrible temptation in apocalyptic times. Not being captured by an archetype doesn’t mean avoiding them, however, for that is not possible. Scientists and skeptics too can be ridden by Story. So not being captured means owning up to the presence of these forces: bringing them to consciousness, comprehending their character, and forming sometimes wary alliances with them.

If archetype is too loaded a word for you, you can think instead of genre. We need and enjoy our genres of storytelling, which help us organize the diversity of the stories we rely on. But don’t be captured by any of these genres. Please don’t let your relationship get organized by rom-coms, or your work life inspired by heroic action movies, or your spiritual life deluded by fantasy. And the next time you catch yourself doomscrolling, take it as an invitation to own your own horror. Get to know this most mortal, most religious, and most repulsively embodied of genres. Even if you are not a fan.

The film critic Robin Wood defined the basic horror plot as “normality is threatened by the monster.” Well the monster is here, oh you pretty things, and it looks as though it’s here to stay. Might as well make room for the holy peculiar.

I, like many people, prefer texting to calling. So why does Apple think I want to talk to Siri out loud? 

I understand that in some circumstances talking out loud is easier, but when I’m in a public place I’d rather type notes to my virtual assistant than look like I’m talking to myself. This approach is particularly easy on my Mac, where I have a big keyboard ready to be used. 

If you’d also like to keep your conversations with Siri private, you can dive into the Accessibility settings to enable the Type to Siri feature and stop Apple’s assistant from responding to you out loud. 

How to turn on Type to Siri

Turning on Type to Siri is easy and the same on iPhone, iPad, and Mac devices. Keep in mind that the change only affects the gadget you’re using, so if you’re tweaking the settings on your Apple computer, it won’t affect your iPhone.

Start by opening the settings application for your device. On a Mac, you can find System Settings on the dock or by clicking the Apple logo in the top-left corner of your screen and clicking System Settings. On your iPhone or iPad you can find the Settings app either on your homescreen or in the app drawer. 

[Related: Simplify your life by creating routines for Alexa, Siri, and Google Assistant]

Continue by scrolling down on the left-sidebar, going to Accessibility, and clicking Siri.

From here, toggle the switch next to the Type to Siri option to activate it. 

From now on, whenever you summon Siri, your system will show you a text box and allow you to type instead of waiting for you to talk. On the Mac, this happens in the top-right corner of the screen. On your iPhone or iPad, your on-screen keyboard will open along with a box prompting you to chat to Siri. Type a question or request and, as always, you’ll get a response. 

No matter what device you’re using, all Siri functionalities will stay the same, so you’ll still be able to ask follow-up questions like you can when using Siri out loud. 

Note that, on the Mac, you can set a keyboard shortcut for Siri, which is perfect considering you’re using the keyboard for the actual conversation. In Settings, head to Siri & Spotlight and click the dropdown menu next to Keyboard shortcut. You can choose between three default shortcuts or create your own by choosing Customize. 

How to prevent Siri from responding out loud

You’re not talking out loud to Siri but, by default, Siri will still respond by talking back to you out loud. To change this and have her reply with a written response instead, head back to the Settings application and go to the Siri and Spotlight (Mac) or Siri and Search (iPhone and iPad) section. 

[Related: Siri, Alexa, and Google Assistant all have alternate voices. Here’s how to find them.]

Click Siri Responses and toggle off the switch next to Voice feedback. 

Note that on mobile you can’t prevent Siri from talking back at all times, and it’ll keep responding out loud whenever you’re driving. This will also happen when you’re using headphones and your iPhone’s screen is off. But the rest of the time Siri will communicate with you using text.

One of the most ubiquitous sights on the road is an 18-wheel truck. These large, loud vehicles are a prolific presence on America’s interstates, and are made up of two big components: the tractor, which does the pulling and is where the driver is, and the trailer, where the stuff goes. 

In an effort to clean up the relatively large emissions that come from this part of the transportation sector, some companies are working on electric tractors that can pull trailers: Freightliner has a model called the eCascadia, Tesla has its Semi, Volvo its VNR, and others are working on it, too. But a relatively new company called Range Energy is focusing on the trailer itself, equipping it with batteries, a motor, and other intelligence. The trailer can be paired with a tractor burning diesel, or an electric one, like one of those eCascadias. 

Currently, there are about 3.5 million trailers in the United States, according to a company called ACT Research.

Range Energy is led by Ali Javidan, an early Tesla employee and veteran of Google and Zoox, the autonomous car company now owned by Amazon. Javidan also brings something else to the table: experience towing things. “I’ve always been around equipment, cars, trucks, stuff like that,” he says. “A few of my uncles had car dealerships, mechanic shops, lots of land in Sacramento. And so growing up, one of my first experiences driving was towing cars from the dealership to the service center, or moving boats around the farm, or things like that.” 

So while he points out that he has “very, very limited time in a class-8 tractor trailer,” which is a big 18-wheeler, he adds that he has “lots of towing empathy.” 

[Related: Futuristic aircraft and robotic loaders dazzled at a Dallas tech summit]

Range’s RA-01 product looks like a regular trailer—typically a big, boxy, and boring presence on the road—but has some key changes. There’s a motor that turns one of the axles at the back of the trailer. That motor gets the power it needs from an onboard battery pack, which isn’t inside the trailer (where it would interfere with cargo space) but is below it. There’s also what Javidan refers to as “smart kingpin.” A kingpin on a big 18-wheel truck is the point where the trailer connects to the tractor. What makes the Range Energy kingpin different from a regular kingpin is that it senses what the tractor is doing. “It’s a real-time measurement of how hard the tractor is pulling,” Javidan says.

Because it gathers this information, the trailer can be “kind of like an obedient dog on a leash,” he says, with the goal of making the trailer feel “essentially weightless” for the tractor. The trailer wouldn’t ever push the tractor, though. 

The result, according to Range, is that if this trailer is paired with a diesel-burning tractor, that tractor could get around 35 to 40 percent better fuel efficiency. And if it were paired with an electric tractor, it could add about 100 miles of range or more. 

Another benefit potentially arises from what happens when a truck towing a Range trailer goes downhill. That’s because of regenerative braking, which uses the motion from the wheels to charge the battery back up and simultaneously slow the whole rig down. That means that the truck’s brakes get less wear and tear, too. “The second-biggest maintenance item on a trailer is brakes,” he says. (Tires take the top slot.) Plus, Javidan says that the system has a stability boost going downhill, “because we’re dragging from the trailer.” 

The most obvious negative tradeoff that comes with electrifying the trailer is weight. “It adds about 4,000 pounds to the total system,” Javidan says. (A tractor-trailer rig has to stay below 80,000 pounds in total, although an electric tractor gets an additional 2,000 pound allowance.) For trucks hauling something heavy, like soda, this could affect the amount of goods they can transport in one load. But many trucks carrying stuff have “cubed out,” Javidan says—meaning that the truck’s interior space fills up before hitting the maximum weight limit. (Just think about an Amazon box filled packaging around something small, like toothpaste, and you get the idea.) 

Javidan says that they’ll start beta testing next year, with deliveries to customers planned for 2025. “You will start seeing these trailers on the roads in real volumes starting in 2026,” he predicts. 

There’s good reason for regulators and companies to work on cleaning up this transportation sector, both from a climate-change perspective and a public-health one. If you consider buses and medium- and heavy-duty trucks, those big rigs make up just 6 percent of vehicles on the roads in the US, but account for sizable portions of greenhouse gas emissions and nitrogen oxides (NOx). In other words, they are “disproportionately emitting emissions,” says Stephanie Ly, the senior manager of eMobility Strategy and Manufacturing Engagement at the World Resources Institute. 

The NOx emissions have “major public health impacts,” she says. Exposure to this diesel-heavy industry has serious ramifications for people, with repercussions like “years of life lost” as well as “asthma, cancer, infertility, and so many other negative effects, particularly for those that live nearest to high-traffic truck centers,” she says. And these groups, Ly adds, “are primarily communities of color, and communities that are lower income, or have less access to different types of employment, so they’re especially vulnerable.”

With Range Energy’s plan to electrify the trailer, Ly notes that “it’s absolutely fascinating what they are proposing.” That said, just as there are multiple companies working on creating electric tractors that do the pulling, other firms also are working on electrifying the trailer, too. ConMet eMobility, ZF, and Einride all represent potential competitors for Range. 

“I will say in the trucking sector, there’s quite a bit of brand loyalty within the supply chain,” Ly adds. In other words, any new player might have something of a long haul ahead of them as they try to pull onto the highway, get into the right gear, and travel down that open road.

This article was originally featured on Undark.

It started with a Google search for prescription medications I might get online.

Almost immediately, ads from telehealth companies began chasing me around the internet, promising access to drugs to make me prettier, skinnier, happier, and hornier. Several of these companies sell anti-aging creams. While decidedly pro-aging, I don’t love the visible effects of my sun-soaked youth. “Sure,” I thought. “Why not?”

Within the hour I had joined the millions of Americans who get prescription drugs from providers in cyberspace.

Telehealth, an umbrella term for health care delivered by phone, video chat, or messaging, exploded during the pandemic. Since then, it has become a mainstay of many medical practices. Also riding the telehealth wave is a raft of internet-based companies that facilitate prescribing—and often sell—medications for complaints that because of time, money, or embarrassment people don’t want to discuss with a doctor face-to-face.

My experience represents the sunny side of direct-to-consumer telehealth. It took about 15 minutes to fill out a medical history, upload photos of my face, and enter my credit card information on forhers.com, a website run by the telehealth company Hims & Hers Health, Inc. Twenty minutes later, a nurse practitioner had prescribed a Hers product containing tretinoin, a well-studied Vitamin A derivative that smooths fine wrinkles and fades dark spots. Six days after that, it showed up at my door.

Compared to the conventional health care system, the process of obtaining the prescription felt like scoring a fast pass at Disneyland.

But last year, urologist Justin Dubin discovered a darker side of DTC telehealth. Alarmed at seeing patients who had been prescribed the hormone testosterone without good medical reason or warnings about side effects, Dubin went undercover as a secret shopper at seven platforms targeting men’s health. Following a script, he described himself as a happily married 34-year-old man bothered by low energy, decreased sex drive, and erectile dysfunction. “I read about low testosterone and its symptoms online,” he told potential prescribers, “and I am worried that I might have it.”

Dubin, who like his alter ego was 34, submitted his own lab results showing healthy hormone levels. “It was pretty clear that I did not need testosterone,” said Dubin, who treats patients at Memorial Healthcare System in Florida. Nonetheless, as he detailed in a study published in JAMA Internal Medicine in December 2022, providers working for six of the seven companies defied medical society guidelines to offer to prescribe him injectable testosterone. They also offered to sell him several other testosterone-boosting drugs and supplements that were inappropriate for his hypothetical case.

“This was just egregious, what Dubin found,” said Steven Woloshin, a professor of medicine at Dartmouth. Even though Dubin’s script made it clear that he and his wife wanted to have a child in the near future, half of the telehealth providers offering testosterone failed to warn him that, in addition to other risks, taking the hormone can reduce fertility. “For this simulated patient it could interfere with his goal to have children, and they were treating something he didn’t have,” said Woloshin. “It just seemed like it was just a terrible practice of medicine.”

Woloshin said the paper has big implications about the poor quality of online care: “There’s no reason to think that this is unique to urology.”

In an accompanying editorial, Woloshin, and my former colleague Lisa Gill, an investigative reporter at Consumer Reports, called for better oversight of standalone DTC telehealth services. “Consumers need to be aware of the potential for bad care,” they wrote, “and regulators need to do more to protect them.”

For telehealth, everything changed with the onset of the Covid-19 pandemic. In the U.S., telehealth use skyrocketed with lockdowns in the spring of 2020 and then stabilized at 38 times higher than pre-pandemic levels by early 2021, according to a report from the consulting firm McKinsey & Company.

By and large, DTC companies fall into two main business models. Companies such as Teladoc, Amwell, DoctorOnDemand, and MDLive most closely resemble traditional medical practices. They take insurance, send prescriptions to your pharmacy, and offer a range of services, including urgent care, primary care, psychiatry, mental health counseling, and dermatology.

Then there are a host of platforms that treat a narrower set of conditions, such as Ro—which focuses on skin, hair, fertility, weight loss, and sexual health—and the men’s health clinics that Justin Dubin shopped. These companies typically don’t take insurance and charge little or nothing for patient visits. Instead, they make money by selling products that their providers prescribe. “It’s simply a route to market for a drug,” said Mark VanderWerf, a telehealth entrepreneur and consultant.

From the patient perspective, the DTC approach has demonstrated benefits, said Ateev Mehrotra, a physician and health care policy scholar at Harvard Medical School who started researching telehealth a decade ago. As I discovered, it’s efficient. No travel time; no scrolling on my phone in a waiting room. “Patients’ time is valuable,” he said. “And the convenience of it is obviously really critical.”

Plus, because of the efficiencies built into the telehealth model, said Mehrotra, “many of these companies can provide care at lower cost.” That’s a huge plus for people facing poor insurance coverage or high deductibles.

Those virtual clinics can also specialize in serving populations that otherwise struggle to get care, said Crystal Beal, a family medicine physician who provides treatment and education through the website QueerDoc. Because many doctors don’t feel confident and comfortable providing gender-affirming care, Beal told me, some of their patients previously had to travel more than 200 miles for appointments. DTC options, they said, are sometimes “really the only option for trans and gender-diverse patients.”

The explosion of DTC telehealth is a direct result of the failures of our health care system, said Ashley Winter, who until recently served as the chief medical officer of Odela, a DTC telehealth company focused on women’s sexual health. Winter previously treated both men and women as a urologist and sexual medicine physician at a large managed care organization, and she said she joined Odela to help more patients: “I was drowning in need.”

While DTC platforms can compensate for some of the shortfalls of America’s health care system, they can also bring out its worst money-grubbing tendencies.

Mehrotra is most concerned about what he refers to as “solutions oriented” platforms where people come seeking drugs for, say, weight loss or erectile dysfunction that company providers dutifully prescribe. “They really turn the clinical model on its head,” he said. Good medical practice involves taking a history, diagnosing the patient, and then deciding on what treatment is best for the patient, he said, not starting from the treatment and asking whether the patient is right for it.

Of course, you can easily find brick-and-mortar versions of that approach to medical care—men’s health clinics peddling testosterone and penile injection therapies, for example, or clinics promoting diabetes drugs for weight loss. But the DTC model supercharges that clinical model, allowing providers to reach far more potential customers.

The system is built for throughput. As in my case, people often discover DTC telehealth websites through targeted ads promoting access to prescription medications. Unlike traditional drug advertising, which is more closely monitored by federal regulators, marketing from DTC telehealth providers often neglects to mention side effects, or promotes uses of drugs that haven’t been approved by the Food and Drug Administration.

Once a user clicks on one of those ads, they are transported to a website where chatbots may answer questions and guide potential customers to a treatment. Artificial intelligence algorithms can tailor questions about each patient’s medical history and suggest a possible diagnosis to the provider. With electronic assistance, human clinicians can complete hundreds of e-visits daily, according to a 2019 JAMA viewpoint by Mehrotra and colleagues.

That model offers little incentive to provide referrals or other care for patients. Dubin pointed out that given normal testosterone levels, his hypothetical patient’s symptoms should have triggered further investigation for, say, uncontrolled diabetes, a mental health problem such as anxiety or depression, or alcohol or drug use. A lot of these online men’s health clinics are a “one-stop shop for a Band-Aid,” said Dubin, and aren’t invested in getting to the source of the problem.

The profit model, critics say, also presents obvious incentives for physicians to prescribe more drugs. Queer Doc founder Beal is critical of any practice, be it DTC telehealth or an in-person clinic that makes money on the medications prescribed. “If you are financially incentivized by the product you’re selling, you are going to try to sell more of it,” they said.

There’s limited data on whether telehealth sites that focus on specific ailments overprescribe, although Dubin’s paper suggests that at least some companies are offering drugs too enthusiastically.

Some recent cases also point to problems in the industry. Last year, for example, federal agencies launched investigations into DTC telehealth companies Cerebral and Done Global regarding the prescription of stimulants to treat ADHD. An investigative series in The Wall Street Journal cites current and former employees who describe corporate environments they say pressured clinicians to prescribe the drugs based on cursory appointments with little follow up.

Industry sources chalk up such cases to the work of a few bad actors, rather than inherent flaws with the clinical model. Ashley Winter told me that she followed the same medical guidelines at the DTC telehealth company Odela as when she treated patients in person. While Odela does sell the drugs its providers prescribe, that practice is no more a conflict of interest than surgeons profiting from the procedures that they recommend, she said: “You just have to be ethical.”

The DTC telehealth company Ro, which offers treatment for sexual health, fertility, hair, skin, and weight loss, has layers of safety checks, according to an email from Nicholas Samonas, the company’s associate director of communications. The company has an audit program, he said, and uses software that flags when a medication may not be appropriate for a patient.

Samonas pointed me a company-sponsored study of 10,000 male patients, which found that men treated for erectile dysfunction through Ro experienced the same type and distribution of side effects, and discontinued medications, at about the same rate as in published studies of men receiving in-person care. Those results, published in the Journal of Urology and Research in 2020, suggest that telehealth treatment was on par with conventional care, according to Ro researchers.

However, in a 2021 study published in the American Urological Association’s Journal of Urology, a panel of experts gave Ro and Hims mixed scores on how well they adhered to the organization’s guidelines for treating erectile dysfunction. Both companies did a decent job advising patients on risks and benefits of medications, but performed poorly in other areas, notably not telling men with low testosterone that drugs such as sildenafil (Viagra) may work better when combined with testosterone therapy. Neither company prescribes testosterone.

Dubin is a huge proponent of telemedicine in general, but worries that, left unchecked, the DTC model can potentially introduce questionable medical practices to vast new audiences. “Direct-to-consumer telemedicine has a lot of room to grow,” he said. “There’s a lot of things that need to be worked out in that space to make sure that we’re providing good care.”

So exactly who is minding these virtual combination clinic-drugstores?

The onus mostly falls on state medical boards—groups of physicians charged with monitoring other physicians. But the boards typically just respond to complaints, rather than go looking for bad actors, and disciplinary action for telehealth prescribers appears to be rare.

“The disciplinary system is just totally unresponsive and inactive,” said Rebecca Haw Allensworth, a professor at Vanderbilt Law School.

As for those ads trailing me around the internet, the FDA is responsible for ensuring that promotions for prescription drugs are truthful, balanced, and accurate, FDA press officer Charlie Kohler wrote in an email. By law, ads that refer to a prescription drug by name and make claims about what it does must include a balanced description of benefits and risks.

In practice, that doesn’t always happen. The online company Nurx ran an ad on Facebook touting the anti-aging effects of tretinoin, but neglected to list (admittedly mild) side effects such as skin irritation and increased sun sensitivity. Similarly, a RocketRx ad for sildenafil, generic Viagra, promotes the drug for erectile dysfunction, but doesn’t tell you that it can cause dizziness, headache, flushing, and stomachache as well as more serious side effects such as painful, prolonged erections, abnormal vision and a sudden loss of hearing. And a MaleMD ad doesn’t mention that the prescription finasteride in its Hairsy 3-in-1 hair growth medicine can cause testicle pain, decreased sexual desire, and an inability to have or maintain erections.

In addition, while doctors commonly prescribe drugs for uses not approved by the FDA—beta-blockers to lessen stage fright, for example, or the diabetes drug Ozempic (semaglutide) for weight loss—the agency bans “off-label” promotion directly to consumers. But, again, DTC telehealth sites often appear to exploit a loophole allowing them to ignore those regulations.

The Hims website, for example, promotes off-label use of the antidepressant Zoloft (sertraline) for premature ejaculation. Click the “early climax” on the forhims.com home page and an animated cactus pops out of a pot, cheerily announcing: “you’re on your way to lasting longer in bed.” But despite the appeal to young men worried about their sexual performance, the site’s lengthy discussion of sertraline never says that the drug carries a black box warning—the strongest type—about the increased risk of suicidal thoughts and behaviors in teens and young adults.

In an emailed response, Hims & Hers company spokesperson Khobi Brooklyn noted that customers receive safety information on products as part of the consultation process and with prescription shipments. They also have unlimited access to health care providers to ask questions about side effects, she wrote.

Questions about the legality of the DTC telehealth ads that Kristina Bitzer saw online prompted her to dig into the topic during law school. Her analysis, published in the Northern Illinois University Law Review in 2021, found that many DTC platforms fall into a regulatory gray area defined by what they are not. The DTC companies themselves aren’t medical providers, because they contract with the professionals who provide care. They aren’t pharmaceutical companies, either, because they don’t actually make the drugs that they promote and sell. But they are also not online pharmacies, because they contract with outside companies to fill prescriptions.

Instead, they’re middlemen who can exploit that status to market drugs online, free from government oversight.

Brooklyn confirmed that Hims & Hers does not consider itself to be a medical provider, drug maker, or pharmacy and so is not subject to FDA regulations for prescription drug marketing and promotion. “Hims & Hers connects people seeking care to independent licensed healthcare providers who work through the Hims & Hers telehealth platform,” she wrote. When asked about the specifics of purchasing and receiving a treatment, Brooklyn noted: “Prescriptions are fulfilled by one of our partner or affiliated pharmacies, who ship the product directly to customers.”

The FDA’s Kohler would not comment on specific ads, but he did acknowledge that some companies are out the agency’s purview. Social media companies, whose policies appear more lenient than federal law, have also been permissive toward DTC drug advertising. For example, Meta, the parent company of Facebook and Instagram, allows ads that “share information around medical efficacy, accessibility and affordability of different types of treatments,” company spokesperson Rachel Hamrick wrote in an email. No mention of risks is required.

In theory, DTC telehealth is a good idea, said Bitzer. The problem, she said, “is that without any kind of real governance of the system, and where these telemedicine platforms are saying, ‘Well, we don’t fit into any of that, we’re doing our own thing,’ there’s a real issue for patient safety.”

I wondered if I got suckered by ads, or if my prescription face cream was as good of a deal as it seemed like at the time. As a point of comparison, I made an appointment with a local dermatologist, who did a skin-cancer check, noted mild psoriasis on the back of my neck, and wrote me a prescription for tretinoin. The drug was cheaper at my local pharmacy, I discovered, but under my health plan I had to pay $190 out of pocket for the doctor visit. Although I got a more thorough exam in person, it was a far more expensive way to get the prescription.

In addition, the Hers cream is a nicer moisturizer. And, in any case, like many of these platforms, Hers automatically signs you up for a recurring subscription and I haven’t gotten around to cancelling.

But for many patients, the stakes are much higher. It makes sense that regulators should specifically address the DTC market.

In their JAMA Internal Medicine editorial, Woloshin and Gill called on the Federation of State Medical Boards, a nonprofit organization representing medical and osteopathic boards in U.S. states and territories, to be proactive—perhaps by encouraging state boards to periodically conduct undercover spot checks of randomly selected telehealth sites.

Whether state medical boards are willing and able to provide that kind of oversight is another question. State boards have no jurisdiction over businesses, just individual practitioners, said Lisa Robin, chief advocacy officer at the FSMB. And in the absence of a complaint, state boards don’t audit practices, said Robin. “That’s just not how the system is set up in this country.”

That traditional regulatory model has started to fall apart when it comes to DTC platforms, said Mehrotra. The company, not individual providers, decides how to create questionnaires, screen patients, and advertise products, he said. So while it seems like the company should be regulated, said Mehrotra, “we don’t have a regulatory framework for that.”

However, Allensworth, the law professor, is leery of imposing extra regulations on DTC platforms. Putting special limitations on where and when doctors prescribe can limit access to care, she said. “We have such a terrible health care shortage in this country,” she said. “And I just think that’s almost always going to be the wrong way to respond to it.” Medical boards do have the authority to undertake robust investigations and discipline errant telehealth providers, she pointed out. Like Woloshin and Gill, she’d like to see a national effort for the boards to do so.

As for anything-goes advertising, Bitzer suggested in her analysis that, at the very least, Congress could update laws so that telehealth platforms are subject to the same regulations as drug companies marketing and promotion.

In the near term, the FDA seems unlikely to take action. Spokesperson Charlie Kohler said that the agency doesn’t comment on future potential regulatory activity, but telehealth is not listed on any of the FDA’s agendas for this year.

In the meantime, as a minimal check on who is treating them, prospective customers can look up their provider’s credentials and disciplinary record on the FSMB-run website DocInfo.org.

Patients need to be cautious, said Woloshin. “Until someone starts regulating this more carefully,” he added, “there’s a potential for harm.”

There’s an aviation term called the “death spiral”—when pilots’ skewed sensory perceptions contradict the accurate readings on their instruments, causing confusion and leading to bad course corrections. As the name implies, this often leads to tragic consequences—many experts believe such an issue contributed to John F. Kennedy, Jr.’s fatal crash in 1999, as well as the 1959 tragedy that killed Buddy Holly, Ritchie Valens, and The Big Bopper. Disorientation was also one of the causes in the 2021 helicopter crash that claimed Kobe Bryant’s life.

Such a scenario is terrifying enough on its own—but imagine a similar situation while floating in the vacuum of space. With no gravitational pull and few, if any, points of reference, working in such an environment could quickly become disorienting and potentially dangerous as astronauts lose their sense of direction.

Although NASA astronauts receive copious training to guard against spatial disorientation, the issue is still a huge concern, especially as private companies increasingly expand their own projects with both space tourism and governmental contracts. Thanks to a team of researchers, however, wearable sensors enhanced by vibrotactile feedback might one day help keep astronauts feeling grounded.

“Long duration spaceflight will cause many physiological and psychological stressors which will make astronauts very susceptible to spatial disorientation,” Vivekanand P. Vimal, a research scientist at Brandeis University’s Ashton Graybiel Spatial Orientation Lab, explained in a recent profile. “When disoriented, an astronaut will no longer be able to rely on their own internal sensors which they have depended on for their whole lives.”

To explore these issues, Vimal and their colleagues conducted a series of trials involving 30 participants. The team taught 10 of them to treat their vestibular senses (which pick up onwhere they are in space and where they are going) with skepticism. Another 10 volunteers received the same training alongside the addition of vibrotactors—devices attached to their skin that buzz depending on their geospatial positioning. The final 10 participants only received the vibrotactors with no training whatsoever. Subjects then wore blindfolds and earplugs while white noise played in the background, and took their place inside an intentionally disorienting “multi-axis rotation device” (dubbed MARS).

Similar to an inverted pendulum, MARS first rotated upright subjects from side-to-side around a central axis to act as an analog to everyday gravitational cues on Earth. Subjects then used two joysticks to attempt to remain stabilized without swinging into either side’s crash boundary. A second phase involved the same parameters, but with the cockpit shifted on a horizontal angle (with the participants facing the ceiling) to better approximate a space environment without Earth’s gravitational reference points. Throughout each subject’s 40 trials, vibrotactors on 20 of the 30 participants buzzed if they shifted too far from a central balancing point, thus potentially queuing them to correct their position with their joysticks.

Vimal, alongside co-authors Alexander Sacha Panic, James R. Lackner, and Paul DiZio, published the results in a new study published on November 3 with Frontiers in Physiology. According to the team’s findings, all participants first felt disoriented during the analog tests due to conflicting input from their vestibular systems and vibrotactors. Those with prior training with their sensors performed best during the space phase, while training-only participants without the wearables “crashed” more often. This third group also accidentally destabilized themselves more frequently than the other two. However, the subjects performed far better while situated in the Earth analog position, with or without the vibrotactors’ aid—Vimal’s team suspects the devices may have been too weak, or participants needed more time to adjust to the devices.

With further testing and refinement, Vimal’s team believes engineers could integrate similar wearables into astronauts’ suits to provide orientation aid, both inside spacecraft and outside space stations. They may be small additions, but they are some that could save explorers from some very serious, scary, and possibly even fatal circumstances.

When you use the open internet, your identity generally remains unknown to other users. However, the device you’re on is always tagged with an IP (internet protocol) address, which can reveal details about where it’s located. To be more private, you can hide your true IP address with a VPN, or virtual private network. 

However, a VPN is not a privacy panacea. If you’re thinking of using one, it’s best to know how a VPN works, what it’s capable of, and what others can still learn about you while you’re online. 

Think of IP addresses as devices’ postal mailing addresses on the internet. Each website also has an IP address linked to the server that hosts it, and the domain name system (DNS) acts as a phone book that keeps track of which human-readable website names are correlated with which IP addresses. For example, one of PopSci’s IP addresses is 151.101.2.132. (You don’t need to type that in every time.) These IP addresses give routers—the postal processing centers of the internet, different from the home WiFi routers that connect you to the internet—information about where to send the data package, and how to get there. 

These routers are operated by internet service providers like Verizon, AT&T, and Comcast, and contain maps of the larger internet. Once they decode the information contained in an IP address, they can plan an optimal route for the data. VPNs complicate this route a bit in the name of added privacy. 

“Each message [sent on the internet] carries not only the destination address but the source address—the sender and the receiver. You have to put a send and return address,” says Vyas Sekar, professor of electrical and computer engineering at Carnegie Mellon University. “The VPN is a middle person between the sender and the receiver. In this case, the sender can hide themselves from the receiver.”

That means if you want to view content on a website but want to hide who you are because you want to keep your browsing history private, a VPN can keep your identity in the shadows.  

What does a VPN do?

VPNs are usually run by hosting providers, companies that operate physical servers that are connected to the internet, and also offer their services through the cloud. “They may have a pool of their own IP addresses, and they have servers that are relaying these messages,” says Sekar. “They may have different locations that you can choose from. They may have different servers distributed through the countries, and they have to be well-provisioned to handle this load.”

When you turn on a VPN service, either through an app on your phone or a plug-in extension on your browser, you won’t go directly to the website from your home network. Instead, your request will route through the VPN service, which then visits the website on your behalf. That way, you can still access the website, but it will look to the website like everything is coming from the IP addresses hosted by the VPN service. 

[Related: You should switch to a browser with its own VPN]

Organizations and businesses can also use VPNs to prevent the public from accessing a private network. Some colleges, like Carnegie Mellon, will have specific resources that can only be accessed through IP addresses located on campus. “When you want to talk to a server inside a private network like CMU, you talk to a VPN server first,” Sekar explains. “That server tunnels under the gates that protect the private network. Instead of directly sending a package to my lab’s server, I’ll route my message through the CMU VPN server. It pretends that I never left the campus.” 

Why use a VPN?

People use VPNs for different reasons. “One is for privacy,” says Sekar. “The other interesting use case is to break geofencing.” 

For example, Netflix offers different content in different countries due to licensing variations across the globe. So if you wanted to see a movie that’s not available on Netflix US but is available on Netflix UK, you could use a VPN to pretend that you’re in the proper country. 

[Related: The best VPNs of 2023]

Although VPNs are mostly legal, censorship-heavy countries will often try to block them because these services can allow users to bypass censorship systems. To continue the postal service analogy, if you wanted to get a note to someone whose address is on the no-send list at your local post office, instead of sending the letter directly to them, you’d send it to a middle person who would take your letter out of its envelope and put it into a new one with the recipient’s address on it, Sekar explains.

Can you still be tracked if you use a VPN?

VPNs don’t completely shield your privacy. “VPNs don’t prevent things like cookies or other kinds of information from leaking,” says Sekar. There might be things like targeted ads and banners that load on a webpage that are related to the browser sending information; that data may not go through the VPN. “It depends on how the VPN is configured,” Sekar explains. “It’s not really protecting you. It’s just hiding your location. VPNs can’t prevent tracking of user patterns.” 

So, your actual privacy comes down to how reliable and trustworthy the VPN service itself is. You wouldn’t trust just anyone to handle your mail—you would want some assurance that they don’t have a history of reading people’s letters or selling the contents in the packages. The same goes for a VPN service, as low-quality ones could leak or sell your data.

Whether it’s to save messages for posterity, troubleshoot problems, capture memorable gaming moments, or run tutorials, the ability to take screenshots is so essential that it’s built into Windows, macOS, Android, and iOS.

ChromeOS, Google’s operating system for their Chromebook laptops, is no different and has easy-to-use tools to grab screenshots and screen recordings. The OS also provides some basic integrated editing tools for your captured content if you need them.

Start by launching the screenshot toolbar

Taking screenshots on a Chromebook will require you to summon the screenshot toolbar. There are several ways to do this, so pick the one that works best for you. 

Newer Chromebooks come with a dedicated screenshot key—it looks like a circle inside a rectangle and you’ll find it up on the top row of the keyboard. As you might have suspected, pressing this button brings up the screenshot toolbar at the bottom of the screen.

[Related: The best cheap Chromebooks in 2023]

If your Chromebook doesn’t offer this option, you can try the overview key: This is also on the top row of the keyboard, and looks like a rectangle with two vertical lines next to it. This key brings up an overview of all your open windows, but if you hold down Ctrl+Shift and then press it, the screenshot toolbar will appear.

Finally, you can get to the screenshot toolbar by bringing up the Quick Settings panel. Click the clock in the lower right corner of the screen and on the emerging menu, click the Screen capture button.

Customize how you take screenshots on ChromeOS

No matter how you brought up the screenshot toolbar, once it’s open, your options are then the same. On the far left of it you can click either the camera icon or the video camera icon to switch between the ability to take screenshots and screen recordings.

The next three icons to the right let you grab different portions of the screen. Choose the first one to capture the whole screen, the second one to select part of it, or the third one to grab an image of a specific open window. Further to the right is a cog icon that opens the screenshot settings—most of them relate to videos, but you can also choose where in your Chromebook you save your screengrabs.

If you’re making a recording, you’ll be able to include audio from the Chromebook microphone, the feed from your webcam, along with clicks and presses from your mouse and keyboard. These are all useful options if you’re recording a tutorial or a gaming session, for example.

With everything set up the way you want, it’s time to take a screenshot or start a screen recording: For full screen captures, click anywhere on screen; to grab a specific part of the screen, use the crosshair tool to select a portion of it, or if you want to capture a single app window, just click it.  Your Chromebook will snap screenshots instantly, but for videos, you’ll see  a countdown before recording  starts. You can stop them whenever you want by clicking the red button on the shelf at the bottom of the screen.

Editing your screenshots on Chromebook

When you finish capturing a screenshot or screen recording, a small pop up appears in the lower right corner of the screen—click it to see the image or video stored on your Chromebook.

[Related: Revive your old computer by turning it into a Chromebook]

The pop up for screenshots also has an Edit button on it, though you don’t get this with screen recordings. When you click it, the image will open in the basic screenshot editor included with ChromeOS: Hover over the icons at the top to crop and rotate the picture, resize it, add annotations, or change the exposure, contrast, and saturation. 

It’s the annotation tool labeled Draw that’s perhaps most useful for screenshots. A new pane pops out on the right, showing different pen types and colors. Once you’ve made your choices here, you can start scribbling on the image. Click Done when you’re happy with the changes, or Cancel if you don’t want to save them. There’s also a link to launch the image in Google Photos on the web, where you’ll find more editing options.

A router is technically a device for directing packets of data between two or more computer networks, but it’s also shorthand for the piece of tech you’re probably thinking about right now: your home WiFi router. 

A normal WiFi router creates a local area network (LAN) in your home that allows your computers, smartphones, and other devices to connect to your internet service provider’s, or ISP’s, network—enabling access to the open internet. A router is essential if you want multiple devices in your home to access the web.

For example, let’s assume you are reading this article on your smartphone on your home WiFi network. When you tapped the link to this article, your smartphone sent a series of data packets to your WiFi router requesting the contents of this article, which it then forwarded to your ISP’s network, and on to whatever server PopSci is hosted on. That server then sent the contents of this article back along much the same path to your WiFi router, which neatly handed it back to your smartphone.

Do I need a WiFi router?

If you want to connect more than one device to the internet in your home or place of business, then yes, you need a WiFi router. It’s the best way to create a WiFi network that will allow all your devices to go online at the same time. 

[Related: Device won’t connect to WiFi? Here’s what to do first.]

Most WiFi routers are also wired routers. They normally have multiple Ethernet ports so you can connect devices that don’t have WiFi capabilities, or if you want to directly access the high-speed, reliable connection that an Ethernet cable provides.

While you probably need a WiFi router, you might not need to buy one. When you sign up for an internet plan, most ISPs will send you both a modem, which allows you to connect to the internet, and a router, which creates a LAN for all your devices—though the two devices may be combined into one.

What is the difference between a router and a modem?

Although your ISP may combine both a router and a modem into a single device, the two serve different purposes. 

As we’ve discussed, a router creates a LAN and manages data on it. A modem connects your router to your ISP so you can actually browse the internet. 

If you have a router, but no modem, you will be able to create a LAN and send data between your devices. (This is how people used to play multiplayer games with their friends before online gaming.) You just won’t be able to connect to the open internet.

Now, if you have a modem, but no router, you will be able to connect one device to the internet at a time via an Ethernet cable, but you won’t have a WiFi network for multiple devices to connect to.

Are there advantages to getting your own router?

While the routers provided by ISPs will do the job, if you want the best WiFi router you can get, you will likely have to buy one yourself. There are a number of advantages to upgrading your WiFi router:

• Better WiFi routers will support newer versions of the WiFi standard, which allow for faster network speeds and a more stable connection for more devices. For example, the best WiFi 6 routers support gigabit WiFi speeds.
• Mesh routers will allow you to create a single WiFi network with multiple routers, allowing you to cover your whole home with a solid WiFi signal. 
• Most ISP routers aren’t optimized for online gaming. If you want to get the best gaming performance you can over WiFi, you should consider a dedicated gaming router.

Of course, if you just want to connect a smartphone or two to the internet, then any router will do. Just make sure to update your router security settings to keep your browsing safe and secure.

If you think of a particle accelerator, what may come to mind is something like CERN’s Large Hadron Collider (LHC): a multibillion-dollar colossus that’s dozens of miles wide and crosses international borders in the name of unlocking how the universe works.

But particle accelerators take many forms. There are more than 30,000 accelerators in the world today. While some of them—including LHC—are designed to unveil the universe’s secrets, the vast majority have far more Earthly purposes. They’re used for everything from generating beams of brilliant light to manufacturing electronics to imaging the body and treating cancer. In fact, a hospital can buy a room-sized medical accelerator for just a few hundred thousand dollars. And, as of last month, scientists have made another curious addition to the list: the smallest particle accelerator yet.

Physicists have fabricated an accelerator the size of a coin, publishing their work in Nature on October 18. This device is just a tech demo, but its creators hope it opens the gateway to even smaller accelerators that could fit on a silicon chip.

“I consider this paper to be really interesting and cool physics, for sure, and it’s been an effort that’s been going on for a long time,” says Howard Milchberg, a physicist at the University of Maryland, who was not involved with the research.

[Related: The green revolution is coming for power-hungry particle accelerators]

This mini-accelerator is not merely a Lilliputian LHC. Depending on its operational calendar, LHC fires protons or the nuclei of lead atoms around a large circle. This miniaturized accelerator instead fires electrons down a straight line. 

Plenty of other linear electron accelerators have existed, including most famously the now-dismantled two-mile-long Stanford Linear Collider. Traditionally, electron accelerators boost their projectiles by shooting them through metallic cavities, typically made from copper, that contain twitching electromagnetic fields. The chambers thus push particles along like surfers on electric waves. 

But some physicists believe that these old-fashioned accelerators are not ideal. The metallic cavities are prone to errors. They’re also unwieldy and require large equipment. The researchers’ new accelerator instead uses precise laser shots to push the electrons.

Physicists have been trying to make laser accelerators since the 1960s. Called photonic accelerators, referring to the study of light, they can be smaller and more cost-efficient than their cavity-based counterparts. But only in the past decade have lasers become precise and affordable enough for even experimental photonic accelerators to be practical.

Making them smaller, then, brought its own series of daunting obstacles. A major stumbling block had been the fact that engineers didn’t have the sophisticated technology needed to craft a mini accelerator’s tiny parts.

Take the coin-sized accelerator the researchers tried to build. First, it generates electrons using a part repurposed from an electron microscope. Then, the device pushes the electrons down a colonnade: two rows of several hundred silicon pillars, each just 2 micrometers tall, with an even smaller gap between the rows. A laser strikes the top of the pillars, creating electric fields that boost the electrons squeezed inside—at least on paper.

“Making such small features with enough precision is extremely demanding,” says Tomáš Chlouba, a physicist at Friedrich-Alexander-Universität Erlangen-Nürnberg in Germany, and one of the paper’s authors. “You need really top-of-the-line devices…these are not cheap devices, and these are not devices that were available in the 90s.”

[Related: Scientists found a fleeting particle from the universe’s first moments]

But chip fabrication is always advancing. Now, Chlouba and his colleagues could rely on techniques that are already common in the world of semiconductor manufacturing. They fashioned a successful prototype. The device can deliver only about 1 electron per second, a tiny trickle by particle accelerator standards. (The average wire inside the average device in your home carries quadrillions of times more electrons.) Moreover, the electrons have about the same energy as those inside an old-style cathode ray tube television: again, a pittance by particle accelerator standards. 

As a result, “I don’t know how practical it could be,” says Milchberg. Fitting more electrons down the colonnade would be like hitting a bullseye with a shotgun blast, he says.

Indeed, Chlouba makes it patently clear that he and his colleagues are very far away from using this accelerator for anything resembling a real-world application. If they want to do that, they’ll need to make many more electrons, with much higher energies. Milchberg says it is also not clear if batches of electrons can fit together down the colonnade without their negative electric charges pushing them apart.

But if researchers succeed at overcoming these hurdles, Chlouba could imagine a host of applications for particle accelerators that could be arranged on a standard silicon chip. Medical professionals already use electron accelerators to treat skin cancer. With that in mind, some doctors might imagine an accelerator that is small enough to insert inside the body via an endoscope. “This is smaller, cheaper, and fits everywhere,” Chlouba says.

A team of scientists at Northwestern University have developed synthetic melanin that can accelerate healing in human skin. It is applied in a cream and can protect the skin from the sun and heal chemical burns, according to the team. The findings are described in a study published November 2 in the journal Nature npj Regenerative Medicine.

What is melanin?

Melanin is a pigment that is naturally produced in humans and animals. It provides pigmentation to the hair, eyes, and skin. It protects skin cells from sun damage by increasing pigmentation in response to the sun–a process commonly called tanning. 

“People don’t think of their everyday life as an injury to their skin,” study co-author and dermatologist Kurt Lu said in a statement. “If you walk barefaced every day in the sun, you suffer a low-grade, constant bombardment of ultraviolet light. This is worsened during peak mid-day hours and the summer season. We know sun-exposed skin ages versus skin protected by clothing, which doesn’t show age nearly as much.”

[Related: A new artificial skin could be more sensitive than the real thing.]

Aging in the skin is also due to simply getting older and external factors like environmental pollution. Sun damage, chronological aging, and environmental pollutants can create unstable oxygen molecules called free radicals. These molecules can then cause inflammation and break down the collagen in the skin. It is one of the reasons that older skin looks very different than younger skin. 

‘An efficient sponge’

In the study, the team used a synthetic melanin that was engineered with nanoparticles. They modified the melanin structure so that it has a higher free radical-scavenging capacity.

Researchers used a chemical to create a blistering reaction to a sample of human skin tissue in a dish. The blistering looked like a separation of the upper layers of the skin from each other and was similar to an inflamed reaction to poison ivy. 

They waited a few hours, then applied their topical melanin cream to the injured skin. The cream facilitated an immune response within the first few days, by initially helping the skin’s own free radical-scavenging enzymes recover. A cascade of responses followed where healing sped up, including the preservation of the healthy layers of skin underneath the top layers. The synthetic melanin cream soaked up the free radicals and quieted the immune system. By comparison, blistering persisted in the control samples that did not have the melanin cream treatment. 

“The synthetic melanin is capable of scavenging more radicals per gram compared to human melanin,” study co-author and chemist/biomedical engineer Nathan Gianneschi said in a statement.  “It’s like super melanin. It’s biocompatible, degradable,nontoxic and clear when rubbed onto the skin. In our studies, it acts as an efficient sponge, removing damaging factors and protecting the skin.”

According to the team, the super melanin sits on the surface of the skin once it is applied and isn’t absorbed into the layers below. It sets the skin on a cycle of healing and repair that is directed by the body’s immune system. 

[Related: The lowest-effort skincare routine that will still make your skin glow.]

Protection from nerve gas

Gianneschi and Lu are studying using melanin as a protective dye in clothing. The thought is the pigment could act as an absorbent for toxins, particularly nerve gas. 

“Although it [melanin] can act this way naturally, we have engineered it to optimize absorption of these toxic molecules with our synthetic version,” Gianneschi said in a statement

They are also pursuing more clinical trials for testing their synthetic melanin cream. In a first step, they recently completed a trial showing that the synthetic melanins do not irritate human skin. Since it protects tissue from high energy radiation, it could also be an effective treatment for burns cancer patients undergoing radiation therapy often experience. 

This research was funded by the United States Department of Defense and the National Institutes of Health.

The Beatles have released their first song in over 50 years, produced in part using artificial intelligence. Based on a demo cassette tape recorded by John Lennon at his New York City home in 1978, “Now and Then” will be the last track to ever feature original contributions from all four members of the band. Check it out below:

The Beatles dominated pop culture throughout the 60’s before parting ways in 1970 following their final full-length album, Let It Be. Following John Lennon’s assassination in 1980, two additional lost songs, “Real Love” and “Free as a Bird” were recorded and released in 1995 using old demos of Lennon’s vocals. Paul McCartney and Ringo Starr are the two surviving members after George Harrison’s death from lung cancer in 2001. 

Beatles fans have anticipated the release of the seminal band’s “final” song with a mix of excitement and caution ever since Sir Paul McCartney revealed the news back in June. Unlike other groups’ “lost” tracks or recording sessions, the new single featured John Lennon’s vocals “extracted” and enhanced using an AI program. In this case, a neural network designed to isolate individual voices identified Lennon’s voice, then set about “re-synthesizing them in a realistic way that matched trained samples of those instruments or voices in isolation,” explained Ars Technica earlier this year.

[Related: New Beatles song to bring John Lennon’s voice back, with a little help from AI.]

By combining the isolated tape audio alongside existing vocal samples, the AI ostensibly layers over weaker recording segments with synthesized approximations of the voice. “It’s not quite Lennon, but it’s about as close as you can get,” PopSci explained at the time.

The Beatles’ surviving members, McCartney and Ringo Starr, first learned of the AI software during the production of Peter Jackson’s 2021 documentary project, The Beatles: Get Back. Dubbed MAL, the program conducted similar vocal isolations of whispered or otherwise muddied conversions between band members, producers, and friends within hours of footage captured during Get Back’s recording sessions. 

[Related: Scientists made a Pink Floyd cover from brain scans]

Attempts to record “Now and Then” date as far back as the 1990s. In a past interview, McCartney explained that George Harrison refused to contribute to the project at the time, due to Lennon’s vocal recordings sounding like, well, “fucking rubbish.” His words.

And listening to the track, it’s somewhat easy to understand Harrison’s point of view. While compositionally fine, “Now and Then” feels like more of a b-side than a beloved new single from The Beatles. Even with AI’s help, Lennon’s “vocals” contrast strongly against the modern instrumentation, and occasionally still sounds warbly and low-quality. Still, if nothing else, it is certainly an interesting usage of rapidly proliferating AI technology—and certainly a sign of divisive creative projects to come.

The government’s ongoing campaign to investigate and destigmatize unidentified aerial phenomena (UAPs) sightings entered its latest stage this week. A new, easy-to-use online reporting tool is available to file incidents occurring as far back as 1945—but only for those already affiliated with the US government. For now.

Announced on October 31 by the Department of Defense, the system will be overseen by the All-Domain Anomaly Resolution Office (AARO), and is specifically equipped to securely handle sightings involving national security information and military intelligence. The form is only intended for “current and former military members, federal employees and contractors” with “direct knowledge” of alleged US programs related to UAPs.

[Related: NASA wants to use AI to study unidentified aerial phenomena.]

The submission portal includes specific instructions for filing, and specifically prohibits including classified information in an initial report. That said, the AARO is cleared to handle sensitive material, which can be conveyed in potential follow-up interviews.

“The information you submit in the form will be protected,” AARO director Sean Kirkpatrick said via this week’s DoD announcement, adding that any information provided in subsequent follow-up interviews will also be safeguarded according to its proper classification. Any reports must also be firsthand accounts.

Established in July 2022, AARO formed following the dissolution of the Unidentified Aerial Phenomena Task Force. Per its official description, it is charged with “minimiz[ing] technical and intelligence surprise by synchronizing scientific, intelligence, and operational detection identification, attribution, and mitigation of unidentified anomalous phenomena in the vicinity of national security areas.” AARO released its second annual UAP report earlier this year, which dramatically increased the number of documented sightings from 144 to 510 incidents—including 247 from the previous year alone.

AARO’s latest announcement also importantly notes that, although part of its congressional mandate required collecting information regarding “any potential UAP-related programs overseen by the U.S. government in the past,” it has yet to do so.

“We do have a requirement by law to bring those [witnesses] who think that it does exist, and they may have information that pertains to that,” Kirkpatrick said, while also making clear they “do not have any of that evidence right now.”

[Related: Is the truth out there? Decoding the Pentagon’s latest UFO report.]

As AARO currently concerns itself predominantly with classified reports, NASA is continuing its own parallel investigations into declassified and public UAP sightings. In September 2023, the 16-member panel released a new independent study report, which recommended harnessing public trust of the agency alongside artificial intelligence programs to help sift through decades’ worth of UAP incidents.

But if you’re a plainclothes civilian still needing to get that one weird sighting off your chest, take heart: AARO is also planning to launch a similar public portal sometime in the near future.

“We want to hear from you,” said Kirkpatrick.

In Overmatched, we take a close look at the science and technology at the heart of the defense industry—the world of soldiers and spies.

THE YEAR WAS 1998. The computers were blocky, the jeans were baggy, and the US military was sending Marines to Iraq to support weapons inspections. Someone, also, was hacking into unclassified military systems at places like Kirtland Air Force Base in New Mexico and Andrews Air Force Base in Maryland. Given the geopolitical climate, investigators wondered if the cyberattack was state-on-state—an attempt by Iraq to thwart military operations there. 

Three weeks of investigation, though, proved that guess wrong: “It comes out that it was two teenagers from California and another teenager in Israel that were just messing around,” says Jake Sepich, former research fellow at the Center for Security, Innovation, and New Technology. 

The event came to be known, redundantly, as Solar Sunrise. And it illustrates the importance of being able to determine exactly who’s rifling through or ripping up your digital systems—a process called cyber attribution. Had the government continued to think a hostile nation might have infiltrated its computers, the repercussions of a misplaced response could have been significant.

Both cyberattacks and the methods for finding their perpetrators have grown more sophisticated in the 25 years since the dawn of Solar Sunrise. And now an organization called IARPA—the Intelligence Advanced Research Projects Activity, which is the intelligence community’s high-risk-high-reward research agency and is a cousin to DARPA—wants to take things a step further. A program called SoURCE CODE, which stands for Securing Our Underlying Resources in Cyber Environments, is asking teams to compete to develop new ways to do forensics on malicious code. The goals are to find innovative ways to help finger likely attackers based on their coding styles and to automate parts of the attribution process.

Who did the hacking?

There isn’t just one way to answer the question of cyber attribution, says Herb Lin, senior research scholar for cyber policy and security at Stanford’s Center for International Security and Cooperation. In fact, there are three: You can find the machines doing the dirty work, the specific humans operating those machines, or the party that’s ultimately responsible—the boss directing the operation. “Which of those answers is relevant depends on what you’re trying to do,” says Lin. If you just want the pain to stop, for instance, you don’t necessarily care who’s causing it or why. “That means you want to go after the machine,” he says. If you want to discourage future attacks from the same actors, you need to get down to the root: the one directing the action.

Regardless, being able to answer the whodunit question is important not just in stopping a present intrusion but in preventing future ones. “If you can’t attribute, then it’s pretty easy for any player to attack you because there are unlikely to be consequences,” says Susan Landau, who researches cybersecurity and policy at Tufts University. 

In efforts to get at any of the three attribution answers, both the government and the private sector are important operators. The government has access to more and different information from the rest of us. But companies like Crowdstrike, Mandiant, Microsoft, and Recorded Future have something else. “The private sector is significantly ahead in technological advancement,” says Sepich. When they work together, as they will in this IARPA project, likely along with university researchers, there’s potential for symbiosis.

And there might just be some special sauce behind some of the collaborations too. “It’s not an accident that many of the people who start these private sector companies are former intelligence people,” says Lin. They often have, he says, social wink-wink relationships with those still in government. “These guys, you know, get together for a drink downtown,” he says. The one still on the inside could say, as Lin puts it, “You might want to take a look at the following site.”

Who wrote this code?

The project seems secretive. IARPA did not respond to a request for comment, and a lab that will be helping with testing and evaluation for SoURCE CODE once the competing teams are chosen and begin their work declined to comment. (Update: IARPA provided a comment after this story published. We’ve added it below.) But according to the draft announcement about the program released in September, the research teams will find automated ways to detect similarities between pieces of software code, to match attacks to known patterns, and to do so for both source code—the code as programmers write it—and binary code—the code as computers read it. Their tech must be able to spit out a similarity score and explain its matchmaking. But that’s not all: Teams will also develop techniques to analyze how patterns might point to “demographics,” which could refer to a country, a group, or an individual.

The general gist of the program’s approach, says Lin, is a bit like a type of task literary scholars sometimes undertake: determining, for instance, whether Shakespeare penned a given play, based on aspects like sentence structures, rhythmic patterns, and themes. “They can say yes or no, just by examining the text,” he says. “What this requires, of course, is many examples of genuine Shakespeare.” Maybe, he speculates, part of what the IARPA program could yield is a way to identify a nefarious code-writing Shakespeare with fewer reference examples. 

But IARPA is asking performers to go beyond lexical and syntactic features—essentially, how Shakespeare’s words, sentences, and paragraphs are put together. There’s much research out there on those basic matching tasks, and attackers are also adept at framing others (for example, counterfeiting Shakespeare) and obfuscating their own identities (being Shakespeare but writing differently to throw detectives off the scent).

One kind of code, for instance, called metamorphic malware, changes its syntax each generation but can maintain the same ultimate goals—what the program is trying to accomplish. Perhaps that is why SoURCE CODErs will focus instead on “semantic and behavioral” features: those that have to do with how a program operates and what the meaning of its code is. As a nondigital example, maybe many physicists use a specific lecture style, but no one else seems to. If you start listening to someone give a talk, and they use that style, you could reasonably infer that they are a physicist. Something similar could be true in software. Or, to continue the theater analogy to its closing act, “Can you extract the high-level meaning of those plays, rather than the individual use of this word here and that word there, in some way?” says Lin. “That’s a very different question.” And it’s one IARPA would like the answer to.

Although parts of SoURCE CODE will likely be classified (since parts of the informational sessions IARPA held for potential participants were), there is also value, says Landau, in the government crowing not just about attributional achievements but also about the capabilities that made them possible. In the last few years, she says, the government has become more willing to publicly attribute cyberattacks. “That’s a decision that it is better for US national security to acknowledge that we have the techniques to do so by, for example, putting it into a court indictment than it is to keep that secret and allow the perpetrator to go unpunished.”

Why did they do it?

Whatever SoURCE CODE teams are able to do will never be the end of the story. Because cyber attribution isn’t just a technical effort; it’s also a political one. The motivation of the bad actor doesn’t emerge just from code forensics. “That’s never going to come from technology,” says Lin. Sometimes that motivation is financial, or it’s a desire to access and use other people’s personal information. Sometimes, as in the case of “hacktivists,” it’s philosophical, the desire to prove a social or political point. More seriously, attacks can be designed to disrupt critical infrastructure, like the power grid or a pipeline, or to gather information about military operations. 

Often, the finger-pointing part won’t come from technical forensics, but from other kinds of intelligence that, conveniently, the intelligence community running this program would have access to. “They intercept email, and they listen to phone conversations,” says Lin. “And if they find out that this guy who loves his program is talking to his girlfriend about it, and they listened in on that conversation, that’s interesting.”

Update on November 9, 2023. IARPA provided the following comment following the publication of this story: “Every piece of software has unique fingerprints that can be used to extract hidden information. The SoURCE CODE program is looking to leverage these fingerprints to improve cyber forensic tools and disrupt cyber attackers’ capabilities. Quickly pinpointing the attribution of malicious attacks will help law enforcement respond with greater speed and accuracy, and help impacted organizations finetune their safeguards against future attacks.”

Some people work in cubicles, others work in kitchens, but the most intriguing workplace of all may be the coast. Meet the people who head to the ocean instead of the office in our Coastal Jobs series.

Ian Cragg pilots and navigates hovercraft as a first officer for the Canadian Coast Guard out of thehovercraft base near Vancouver, British Columbia, answering search-and-rescue calls across the province.

I joined the coast guard because I wanted to help people. I didn’t end up piloting hovercraft right off the bat; I spent years bouncing between different types of coast guard ships along the coast, from Washington to Alaska and everywhere in between. Hovercraft are rare and special. They’ve been discontinued in most commercial operations because they’re so expensive to make, but when it comes to search and rescue, they’re priceless.

From far away, a hovercraft looks like a normal boat. But if you look under the skirt of our CCGS Siyay, the craft is not touching the water—it floats on a cushion of air. That cushion allows us to travel over everything from water to muddy land—and even break through ice. We do all of that as a 70-tonne machine, going a maximum of nearly 120 kilometers per hour.

These features allow us to rescue a large number of people quickly, get onto land, and get someone into an ambulance far easier than with any other device I can think of. We can even have a small hospital on board with emergency personnel and equipment if the call requires it.

The advantages of hovercraft can also make them difficult to navigate. We’ve got a massive vehicle moving fast, sometimes in a dense fog bank up a narrow river. During assignments on other coast guard vessels, I had 20 minutes to make navigation alterations that would avoid a collision. In a hovercraft, I have 10 seconds. You have to have enough situational awareness to make the right decision every time.

A lot of people get in trouble in areas that can’t be accessed by conventional means. British Columbia’s geography is unique: a lot of mudflats, a lot of beaches. We recently did a call approximately 70 kilometers away in under an hour; it would have been impossible to get emergency equipment there so quickly with a normal boat, which would top out at about 28 kilometers per hour.

People call us for all sorts of problems: medical distress, missing divers, on-board fires, or even when they’ve run out of fuel or had a mechanical breakdown. A container ship could burst into flames. Maybe someone’s hit them and they’re taking on water, or the ship’s lost several of its containers. And if a plane were to go down, there are few other rescue vessels that can quickly reach a downed aircraft.

Sometimes the jobs that seem the simplest—a single person in distress on a calm sea—turn out to be the most difficult. And for some reason, that’s the thing that hits you. For me it was a missing diver. The mission ended up being a recovery. As a recreational diver, I’ve done hundreds of dives outside of work hours in the exact place where that man’s body surfaced. I’m the one who spotted him from the hovercraft, and that experience sticks in my head.

We have a strong network here at the base to help everyone through difficult situations like that. Thankfully, we have captains who train us in a safe environment, but you don’t ever get fully comfortable. That’s why I love it so much. Anything can throw the hovercraft off—maybe your lift settings are off a little, or the wind blows a gust with a bit of extra weight. After several years operating a hovercraft, I’m still learning. Every one of the captains here agrees: you can drive this thing for 20 years and still be surprised.

If just by looking at our watch or cell phone we can know, in real time, our heart rate, the number of steps we take, the calories we burn and the hours of sleep we got the night before, why can’t we also know our blood pressure?

Blood pressure is the force that the blood exerts against the arterial walls. It is defined by two values: systolic, or maximum pressure, which is the thrust of the blood pumped through the body by the contraction of the heart; and diastolic, or minimum pressure, which occurs when the heart relaxes. The American Heart Association considers blood pressure to be normal when it does not exceed pressures of 120 mmHg systolic and 80 mmHg diastolic—which we see presented as 120/80 mmHg.

When values are below 90/60 mmHg, the person is exhibiting hypotension. In athletes, this may be asymptomatic and without risk. But in other circumstances, it causes symptoms such as dizziness, nausea, pallor, blurred vision, confusion and fainting, because the brain isn’t receiving enough blood. Very low blood pressure can be life-threatening because of shock, a state where organs suffer damage due to lack of blood flow. This is more common in the elderly and can be precipitated by sudden changes in position, dehydration, infections, bleeding, certain medications and diseases such as Parkinson’s and diabetes.

Above 140/90 mmHg, the person is said to have high blood pressure. Researchers have calculated that in people ages 40 to 69, for every 20 mmHg increase in systolic blood pressure and 10 mmHg increase in diastolic blood pressure, the risk of coronary heart disease and stroke doubles. Worldwide, some 1.28 billion people between the ages of 30 and 78 have hypertension, most of them living in low- and middle-income countries, and more than half of them are not treated, according to a 2021 study published in The Lancet. This is despite the fact that hypertension can be easily detected by measuring blood pressure—at home or in a health facility—and can often be effectively treated with low-cost medications.

Today, a new generation of blood pressure devices aims to make it easier to diagnose—and control—hypertension. Unlike traditional devices, they do without the arm cuff and offer blood pressure values on demand, should the user press their finger on a sensor, or continuously, if measured by a watch, ring or bracelet.

“Regular blood pressure monitoring in all adults would improve hypertension awareness. For those who have hypertension, it may improve their control,” says Ramakrishna Mukkamala, a bioelectrical engineer at the University of Pittsburgh, who coauthored a look at blood pressure measurement using cuff-free devices in the 2022 Annual Review of Biomedical Engineering. “For example, if patients continue to see that their blood pressure is high, they may finally become compliant in taking their medications.”

Leaving the cuff behind

The measurement of blood pressure goes back almost three centuries (see sidebar), leading to the procedure that we all know and that our family doctor performs when we have checkups: A cuff goes around our arm and is inflated, then deflated, in a controlled manner, to determine our maximum and minimum blood pressure.

But the use of inflatable-cuff blood pressure monitors has some drawbacks. For one thing, unless people have home monitors—and a survey of adults ages 50 to 80 in the United States found that only 55 percent of hypertension patients surveyed owned one—they must go to a pharmacy, doctor’s office or health center to learn what their blood pressure is.

Another barrier is that repeated inflation and deflation of the cuff is disruptive and can cause difficulties when, for example, a patient is in the hospital and needs frequent blood pressure monitoring. And a third drawback is that since cuffs don’t allow continuous measurement of blood pressure, they’re only providing a measurement at a specific moment.

The new cuffless devices promise to reveal a more complete picture of physiologic changes in blood pressure that cannot be picked up with spot measurements, and instead give a truer blood pressure profile, says Alberto P. Avolio, a biomedical engineer at Macquarie University in Sydney, Australia, a coauthor of the article in the Annual Review of Biomedical Engineering.

The various cuffless measuring devices are based on methods that, instead of directly determining blood pressure, use sensors to capture various indirect signals. These signals are processed by different algorithms or sets of mathematical procedures to obtain the blood pressure values. It is like inferring fever by measuring an increase in palpitations and sweating instead of using a thermometer, or divining the result of a soccer match from outside the stadium by listening to the screams of the spectators.

One of the detection methods uses optical sensors. The technique is based on the principle of photoplethysmography or PPG: It consists of illuminating a segment of the skin and analyzing the difference between the light that is emitted by the instrument and how much is detected by a photoreceptor. This difference depends on the diameter of the artery, the blood volume and the concentration of hemoglobin (the oxygen-carrying protein) at the measurement site. During the systolic phase, when the heart pumps blood, the difference between emitted and reflected light will be at its maximum, because there will be more blood flow and thus more hemoglobin and other light-absorbing proteins; during the diastolic or relaxation phase, it will be at its minimum. The algorithm relates these measurements to blood pressure.

This is the same method used by the Apple Watch and other devices to measure heart rate, and by the pulse oximeters that became popular during the Covid-19 pandemic to record the level of saturation, or oxygenation, of the blood. It is also the method used by the Swiss company Aktiia’s wristband, available only in Europe for now. This device automatically records blood pressure values over 24 hours, even when someone is sleeping, averaging the results every two hours and displaying the results through an app on a smartphone.

There are also electrical sensors, which are modified versions of the electrocardiogram that measures the electrical activity of the heart; mechanical sensors, used in ballistocardiography and seismocardiography, which attach to the surface of the skin to capture small variations in pressure; and bioimpedance sensors, similar to the instruments that analyze body composition by measuring the body’s resistance to the flow of electrical current.

Calibrated and uncalibrated

There are two broad categories into which these new cuffless blood pressure measurement devices can be grouped: those that require calibration—periodic comparison of the recordings with those obtained with a manual or digital sphygmomanometer—and those that do not.

Both types of devices capture signals from the body noninvasively, from the fingertip, ear or wrist, to name the most common sites. The estimated blood pressure is then displayed or transmitted to nearby devices, such as smartphones or tablets.

One of the measurement methods that require calibration is the pulse transit time, or PTT, which represents the time in milliseconds that the pulse takes to travel between two arterial points: The stiffer an artery is, the higher the arterial pressure will be (because the pulse travels faster) and the lower the PTT will be. This method is the one with the most scientific evidence to date.

Another is based on analysis of the shape and amplitude of the pulse wave, which is the pressure wave depicting the propagation of the blood pumped by the heart through the entire arterial tree, and whose characteristics depend in part on the rigidity of the artery walls. In people with hypertension, the amplitude of the pulse wave is greater because the heart must exert more force to overcome the resistance of the arteries.

More recently, other devices have emerged that use images captured with a camera—like selfies—to detect changes in the PTT or subtle modifications in the color of the face, imperceptible to the eye, that accompany each heartbeat, thus reconstructing the flow of blood under the skin and the shape of the pulse waves.

Uncalibrated cuffless blood pressure measurement methods aim to eliminate the need to cross-check the device’s measurements with those captured by a classic sphygmomanometer or digital sphygmomanometer. They use only machine learning and artificial intelligence to establish, from the signals captured by the sensors, the person’s blood pressure values.

Just as a jet of water can exert more or less force on the walls of a hose if one changes the height or opening of a faucet, the analysis of oscillations or fluctuations in blood volume can be measured when a ring is worn and the arm is lowered, because the finger’s internal blood pressure increases as it receives more blood flow due to gravity. Alternatively, a ring can also obtain measurements of the oscillations in blood volume by periodically applying gentle pressure on the finger. A sensor in a smartphone can also do this analysis when it is pressed following the instructions given by the device.

Other methods for uncalibrated devices use ultrasound waves to visualize variables such as artery dimensions and blood flow velocity, which are also related to blood pressure.

The road to clinical application

The development of these devices for measuring blood pressure without a blood pressure cuff is progressing rapidly, but that doesn’t mean they are ready for use in the medical world. “Unfortunately, the pace of evidence, regulation and validation testing has lagged behind the pace of innovation and direct consumer marketing,” write Stephen P. Juraschek, physician investigator of Beth Israel Deaconess Medical Center in Boston, and colleagues in a review published in September in Current Cardiology Reports.

There is currently no standardized validation protocol to assess the accuracy of cuffless devices, as required by the US Food and Drug Administration, although several of these developments have already received marketing authorization in the US. The European Society of Hypertension, for its part, has issued guidelines that emphasize that, for now, cuffless devices should not be used to make diagnostic and treatment decisions. “The potential clinical value of cuffless blood pressure measurement is enormous. However, the caveats are equally large,” says James Sharman, an expert in blood pressure measurement methods and an exercise physiologist at the University of Tasmania in Australia.

Before wider use can be advocated, it will be necessary to test whether cuffless devices make accurate recordings and whether they have clinical superiority to the current standard of blood pressure measurement, as well as to determine how they would integrate into current medical practice, Sharman adds. In addition, since each device has its own algorithm and method for estimating pressure, each should demonstrate its performance separately.

This work is already underway. According to the ClinicalTrials.gov database, as of October 2023 more than 10 studies to evaluate cuffless blood pressure measuring devices were recruiting participants.

Several studies have already been completed. In Switzerland, a team evaluated the use of such devices for ambulatory blood pressure monitoring (ABPM), which measures blood pressure continuously over 24 hours and is a better predictor of cardiovascular health than non-continuous measurements.

The study involved 67 patients who performed traditional ABPM, using a cuff device, but also had a watch-like optical sensor placed on their upper arm or wrist opposite the arm wearing the cuff. Although there were differences between the measurements of the two devices, the difference was small and within the limits recommended by the international standard. “These results are encouraging and suggest that 24-hour cuff-free ABPM may soon become a clinical possibility,” the authors noted in their conclusions. In addition, study participants said that the optical sensor was more comfortable and overwhelmingly preferred it to its cuffed alternative.

In South Korea, meanwhile, a recent observational study followed 760 people who used a Samsung Galaxy watch approved in that country for one month to monitor blood pressure. The device requires calibration once a month, but interestingly, 75 percent of the participants did not rely on a single monthly calibration, as suggested, but performed more frequent calibrations. This allowed the researchers to determine that poor calibration can affect the device’s measurements and that calibration processes need to be standardized to ensure the device’s proper functioning.

But encouragingly, the study also found that “smartwatch-based blood pressure measurement is feasible for out-of-office blood pressure monitoring in the real world”—as, on average, participants measured their blood pressure 1.5 times per day.

Will the day come when we can accurately know our blood pressure just by looking at our smartwatch or cell phone? “Maybe in time, but not in the near future,” Avolio says. More studies are needed, he says, before cuffless devices can provide reliable quantitative information to track physiological changes with acceptable accuracy.

On October 17, Japan’s military announced it had successfully test-fired a railgun on board a ship. The test was conducted by the Acquisition Technology and Logistics Agency, Japan’s rough DARPA analog, and it was carried out in conjunction with Japan Maritime Self-Defense Force. The railgun is framed specifically as a protective measure: by firing high-speed bullets, the railgun is designed to stop incoming attacks through the air or on the sea.

Most bullets are fired by a chemical propellant—a sparked reaction that ignites the dense gunpowder of a shot, which rapidly expands into gasses that propel a bullet down a gun barrel at high speeds towards a target. It’s a durable design, one continuously tweaked and iterated upon for a full millennia. Railguns still aim to propel a bullet rapidly through the air, but instead of using an explosion to do it, railguns use electromagnetic force to pull and accelerate a metal slug at great speeds and long ranges.

Here’s what it looks like, as shared by the Acquisition Technology and Logistics Agency:

Japan’s military has planned for a railgun since at least 2015, with the goal of a ship-mounted weapon as part of the idea from the start. A 2016 demonstration of a railgun accelerated its projectile to a speed of 4,470 mph, or 5.8 times the speed of sound. That is hypersonic speed, or the range at which a new class of missiles in development by nations like the US, China, and Russia are designed to fly. By making a gun that can shoot projectiles that fly faster than hypersonic missiles fly, a railgun could possibly be a tool that can shoot down such weapons. A proposal for Japan’s 2023 defense budget explicitly refers to railguns as “capable of firing projectiles at high muzzle velocity in rapid succession to counter threats such as hypersonic missiles.”

“Starting in fiscal year 2022, we have been conducting research aimed at establishing the overall technology necessary for early practical realization of railguns, including rapid fire performance and stability during flight, which are important for the practical application of railguns,” a spokesperson from Acquisition Technology and Logistics Agency told Naval News. “At the same time, we have been carrying out demonstration tests aimed at further practical application, such as carrying a railgun on board and conducting actual offshore firing. The Ministry of Defense intends to steadily work towards the early practical use of railguns in order to accelerate the strengthening of Japan’s defense capabilities.”

For the test-firing, the railgun was mounted on the JS Asuka, an Asuka-class research ship that has been a testbed for missile and sensor technologies in the past. Janes reports that crucial details of the weapon, like muzzle velocity and projectile weight, are being kept confidential. In a 2018 test, a Japanese Acquisition Technology and Logistics Agency railgun fired a projectile at a speed of Mach 6.5.

In a March 2022 video from the Agency, the design of a 2020 prototype is discussed. Part of the concern expressed is that accelerating a projectile along a rail at these speeds can cause serious erosion, which damages the weapon and limits its continued and future utility. The prototype fired a 40mm projectile, at the same 4,470 mph (or Mach 5.8) speed as in the 2016 demonstration. 

Railguns can potentially be powerful guns for ships, and they could be used to protect from incoming missiles as the Acquisition Technology and Logistics Agency expresses. Such high-exit velocities also allow the bullets themselves to function as offensive hypersonic weapons in their own right, powerful slugs slamming into far-away buildings or vehicles with tremendous kinetic force. 

Before aircraft carriers, gunships with powerful cannons, ultimately known as battleships, were the dominant vessel for war at sea, with guns that could bombard inland as well as devastate foes at sea. Better long-range sensors, especially radar, and the far reach of planes launched from aircraft carriers during and after World War II, mean that from the Cold War to the present shipboard guns switched from a primary threat to more circumscribed weapons, with ship-launched cruise missiles taking over the role of inland bombardment. Railguns, with the promise of powerful long-range shots that can stop missiles, sink ships, and devastate coastal defenses, offer a path back to relevance for shipboard guns.

The United States Navy has continued to pursue the development of railguns, with the intent that a projectile fired from such could intercept incoming attacks, as well as reach targets as far away as 50 to 100 nautical miles. Part of the challenge is developing a projectile that can work in railguns, as well as from existing cannons on US Navy ships.

In the meantime, the continued development of railguns as a counter-hypersonic weapon should complicate how military planners think about missiles as the answer to ships and seaborne threats.

The wind energy company Ørsted has officially shuttered plans for two New Jersey offshore wind farms, citing rising inflation, interest rates, and supply chain problems. The blow to US green energy infrastructure arrives less than two weeks after the Danish wind industry giant promised to pay the Garden State a $100 million penalty if its Ocean Wind I turbines weren’t online by the end of 2025. But although the company’s plans off the coast of Atlantic City are canceled, similar projects are still underway across the US as the country transitions towards a sustainable energy infrastructure.

“We are extremely disappointed to have to take this decision, particularly because New Jersey is poised to be a US and global hub for offshore wind energy,” David Hardy, Ørsted Group EVP and CEO Americas, said in an October 31 statement. “I want to thank Governor Murphy and NJ state and local leaders who helped support these projects and continue to lead the region in developing American renewable energy and jobs.”

[Related: Atlantic City’s massive offshore wind farm project highlights the industry’s growing pains.]

According to the Associated Press on Tuesday, however, NJ Gov. Phil Murphy had strong words for the company, citing Ørsted’s recent statements “regarding the viability and progress of the Ocean Wind I project.”

“Today’s decision by Ørsted to abandon its commitments to New Jersey is outrageous and calls into question the company’s credibility and competence,” added Gov. Murphy per the AP. He also hinted at impending plans to pursue an additional $200 million Ørsted reportedly pledged for the state’s offshore wind industry. In the meantime, Gov. Murphy reiterated New Jersey’s commitment to offshore wind infrastructure, and said the state will solicit a new round of project proposals in the near future.

Both Ocean Wind endeavors had faced intense scrutiny and pushback from both Republican state legislators and locals, who criticized the farms’ alleged ecological impacts, ocean horizon views, as well as the millions of dollars in subsidies granted to Ørsted. Earlier this month, Ørsted received a lawsuit filed on behalf of an environmental group called Clean Ocean Action alongside multiple seafood and fishing organizations. In May 2023, the Bureau of Ocean Energy Management released an over 2,300 page Final Environmental Impact Statement on Ocean Wind 1, which deemed it responsibly designed and safe for the region’s ecological health.

If completed, Ocean Wind I would have included nearly 100 giant turbines roughly 15 miles off the southeast coast of Atlantic City, New Jersey. Once online, the farm would have annually generated 1.1 gigawatts of energy—enough to power over 500,000 homes. Ocean Wind II was slated for construction next to its sibling wind farm, and would have offered similar energy outputs.

While the Danish company’s plans in New Jersey are dashed, America’s wind farm buildup is still progressing elsewhere—and Ørsted remains a part of that trajectory. The same day as its Ocean Wind announcement, the company confirmed it is moving forward with a $4 billion project, Revolution Wind, off the coast of Rhode Island. If completed, the offshore wind farm will supply clean energy for residents in both Rhode Island and Connecticut.

Meanwhile, a utility company called Dominion Energy received crucial federal approval on Tuesday for plans to construct 176 turbines over 20 miles off the coast of Virginia. Dominion claims the project is the largest offshore project in the US, and will generate enough energy for nearly 660,000 homes upon its estimated late-2026 completion date. According to a 2015 report from the US Department of Energy, wind farms could supply over a third of US electricity by 2050.

Spam’s everywhere: even when you’ve dealt with the junk mail coming through the post and the unsolicited messages clogging up your email inbox, you’ve still got to deal with the spam you get through SMS and other messaging services.

Fortunately, today’s smartphones and messaging apps come with built-in tools for limiting the amount of spam you see. This means that with a little work, you can keep your conversation lists clean and free from junk.

But before technology can do the heavy lifting for you, help it help you by being more careful with your mobile number. To prevent it from ending up in sketchy marketing lists, don’t put it on forms or in any kind of communication if you can help it, and keep it away from your social media profiles on the web.

How to fight spam on iOS’s Messages

The default Messages app on iOS, covering both basic SMS texts and Apple’s iMessage service, lets you block specific numbers: Tap the name or number at the top of any conversation, choose Info and Block this Caller. Blocked texts won’t show up for you at all, but the sender won’t know they can’t reach you. To manage the numbers you’ve blocked, go to Messages and Blocked Contacts from the iOS Settings screen.

[Related: Why it’s still so tricky to track spam calls and texts]

You can also have Messages filter out spam automatically, though this ability only works on texts you receive through Apple’s own iMessage service. From iOS Settings, go to Messages and enable Filter Unknown Senders. This will create a new Filters link at the top of the conversation list in Messages: Tap it to see messages from known senders, unknown senders, or all messages together. This might include new numbers that are not yet in your contact list, so it’s a good idea to check the unknown senders folder from time to time in case you miss anything.

You can also report junk messages to Apple, which doesn’t stop the sender from texting you, but it gives their information to both Apple and your carrier. The company doesn’t explicitly say what good this does, but we’re assuming repeat scammers end up on some kind of blacklist. To report junk, swipe left on a conversation in Messages, tap the red and white trash button, then pick Delete and Report Junk.

How to fight spam on Android’s Messages

For Android users, Google’s Messages should be their default platform for both SMS and RCS texts. This app has built-in anti-spam protections that will automatically detect spam and move it out of your way, but it’s not on by default. To turn on this feature, open Messages, tap your profile picture (top right), go to Messages settings and tap Spam protection.

To see messages that have been filtered out in the app, tap your profile picture, then Spam and blocked. From here, you can tap the three dots (top right), then Blocked numbers to see the current blacklist. While Messages often deals with spam automatically, if the platform isn’t sure about a text, you’ll see a “suspected spam” dialog appear at the top of the message when you open it. If this is indeed an unwanted message, tap Report spam on the dialog to get rid of it.

If the Messages app hasn’t picked up on a spam message, press and hold on it in the main conversation list, then tap the block icon at the top (it looks like a crossed-out circle). Finish by choosing OK on the emerging dialog box to block the number and move the message to spam. The emerging box also gives you the option of reporting the sender’s details to Google, which helps it better detect spam messages in the future.

Fighting spam on WhatsApp

If WhatsApp for Android or iOS is your messaging app of choice, you can deal with spam messages without much fuss. On an iPhone, press and hold on a message in your conversation list to find the Block option. On an Android phone, press and hold on a message on the list, then tap the three dots (top right) and hit  Block.

This will prevent the person behind this number from sending you any more messages. On both Android and iOS, you’ll also see an option to report the sender to WhatsApp as well as blocking them. This means they’ll be known to WhatsApp as a potential spammer, and the platform might ultimately take action against them.

To see the numbers that you’ve blocked, and reinstate them if necessary, tap Settings, Privacy, and Blocked on iOS, or the three dots (top right), Settings, Privacy, and Blocked contacts on Android. WhatsApp won’t identify or filter out spam on your behalf, so it’s up to you to manage this list of contacts.

How to fight spam on Facebook Messenger

Unlike WhatsApp, Facebook Messenger for Android and iOS does attempt to do some kind of spam filtering. Tap the three horizontal lines in the top right of the interface and choose Message requests—you’ll see the messages from people who you aren’t currently friends with or that Facebook Messenger thinks might be spam. Occasionally, you might find genuine messages in here, so it’s worth checking every now and again.

Messages in your main chats list are from people you’re friends with on Facebook, so in theory there shouldn’t be any spam here. But there are exceptions—maybe a spambot has been impersonating a friend of yours, or a scammer has gained access to their account. In that case, verify their identity through other forms of contact and let them know of the situation.

If you go into a conversation with someone, then tap their name at the top, you’ve got three options for dealing with spam or unwanted messages. The first one is Restrict, which won’t result in you blocking the person, but Facebook will auto-archive their messages and won’t send you notifications about them. The others are Block, where the person will no longer be able to message you, and Report, where you’re reporting the account to Facebook for spam messages or something else.

Fighting spam on other messaging apps

We don’t have the space to cover every single messaging app here, but if you dig around you’ll find similar options to these in other platforms. You’ll at least get the ability to block and report spammers, even if your messaging client of choice doesn’t have its own spam filter installed.

If you use Instagram for Android or iOS to message people, you’ll see a Requests link at the top of your direct messages inbox—this is where the platform puts messages from people you’re not following. Meanwhile, you can block and report spammers whose messages get through from inside individual conversations: Just tap the sender name at the top of the chat to find the options.

Over on Signal for Android or iOS, messages from senders who are not in your contacts are flagged up as requests, though they still appear in the main chat list. When you open them, you can accept the message or block the sender. To block someone not flagged up in this way, tap the sender name or number at the top of a conversation and choose Block on the next screen.

Lawn-care equipment—leaf-blowers, lawnmowers, and the like—doesn’t top most people’s lists of climate priorities. But a new report documents how, in aggregate, lawn care is a major source of U.S. air pollution. 

Using the latest available data from the Environmental Protection Agency’s 2020 National Emissions Inventory, the report found that the equipment released more than 68,000 tons of smog-forming nitrous oxides, which is roughly on par with the pollution from 30 million cars. Lawn equipment also spewed 30 millions tons of climate-warming carbon dioxide, which is more than the total emissions of the city of Los Angeles.

“When it comes to these small engines in lawn and garden equipment, it’s really counterintuitive,” said Kirsten Schatz, the lead author of the report and a clean air advocate at Colorado PIRG, a nonprofit environmental organization. “This stuff is really disproportionately causing a lot of air pollution, health problems, and disproportionately contributing to climate change.”

Lawn equipment also contributed to a litany of other air toxics, such as formaldehyde and benzene, according to the report, which is titled “Lawn Care Goes Electric.” But perhaps the most concerning pollutant it releases is the fine particulate matter known as PM2.5. 

PM2.5 is far smaller than the width of a human hair and can lead to health problems ranging from cancer, reproductive ailments, and mental health problems to premature death. The report found that gas-powered lawn equipment belched 21,800 tons of PM2.5 in 2020—an amount equivalent to the pollution from 234 million typical cars over the course of a year.

That outsize impact comes because gas-powered lawn equipment runs on different types of engines than passenger cars. They are smaller—coming in two- and four-stroke versions, which reference the differences in the engines’ combustion cycles—and are generally less efficient, with two-stroke engines being particularly problematic because they run a mix of lubricating oil and gasoline.

“[This] really inefficient engine technology is, pound for pound, more polluting than the cars and trucks,” said Schatz. “Outdoor equipment generates a pretty shocking amount of pollution.”

Emissions also vary widely by state. California and Florida ranked highest for carbon dioxide emissions from lawn equipment, while Florida and Texas topped the list of PM2.5 pollution. While one might expect the sheer amount of lawn care in California, the most populous U.S. state, to rank it higher on PM2.5 pollution, it only comes in 29th. Lower two-stroke engine use accounts for the gap between the state’s carbon and particulate emissions, according to Tony Dutzik, a senior policy analyst at Frontier Group and contributor to the report.

He explained that nationally, two-stroke engines are responsible for 82 percent of PM2.5 from lawn equipment, but in California it’s only 41 percent. Researchers are not exactly sure why the use difference is so stark, but one theory is that California’s history of regulating small engines is paying off. 

“California has consistently led on [small engine] emission standards since the mid-1990s,” said Dutzik. That leadership is ongoing: A statewide ban on small off-road engines, including lawn equipment, is set to go into effect next year. Schatz argues that the rest of the country should follow California’s lead and promote electric alternatives that run on rechargeable batteries.

“We have so many cleaner, quieter electric alternatives available now,” said Schatz. “Battery technology has come a long way.”

Many states and municipalities offer rebates on battery-powered lawn equipment, and more people are making the switch. That’s true even in the commercial lawn-care sector, which is responsible for the bulk of emissions but is more difficult to electrify because companies often need more powerful machines, with longer runtimes, than residential users. 

Kelly Giard started the Clean Air Lawn Care company in 2006, at a time when he said the technology for commercial work was “limited.” But that’s rapidly changing and it’s helped his company grow. His franchisees now serve roughly 10,000 customers across 16 states. 

“At this point,” said Giard of the performance of his electric fleet, “it’s very comparable to gas.”
