In addition to the Snapdragon 8 Gen 3 and the Snapdragon X Elite, Qualcomm has also introduced the S7 and S7 Pro Gen 1 at the Snapdragon Summit in Hawaii. The company said its new chips deliver six times the compute power of their predecessor's, along with on-device AI capabilities. More intriguing, perhaps, is the S7 Pro's micro-power Wi-Fi connectivity, which will apparently allow users to "walk around a home, building or campus while listening to music or making calls."
As The Verge notes, the chip uses Qualcomm's Expanded Personal Area Network (XPAN) technology that can automatically switch a device's connection. When a user strays too far from their phone while their earbuds are connected to it via Bluetooth, for instance, XPAN switches the connection to a Wi-Fi access point. It can deliver 96kHz lossless audio via earbuds, Qualcomm's Dino Bekis told the publication, and it works with 2.4, 5 and 6GHz bands. Bekis also said that users only have to click on a prompt once to connect their earbuds powered by the chip to their Wi-Fi.
Outside of the S7 Pro's Wi-Fi connectivity, the platforms' on-board AI enable better responsiveness to the listener's environment if they want to hear ambient sounds. But if they want to block out their environment completely, the chips are supposed to be capable of Qualcomm's "strongest ever ANC performance" regardless of earbud fit.
These features will only be enabled when headsets, earbuds and speakers powered by the S7 and S7 Pro are paired with devices equipped with the new Snapdragon 8 Gen 3 mobile platform and Snapdragon X Elite, though. That means we won't be seeing products with the new sound chips on the market anytime soon. When they do come out, they'll most likely be meant for Android devices, seeing as Apple has its own ecosystem.

From Hollywood strikes to digital portraits, AI's potential to steal creatives' work and how to stop it has dominated the tech conversation in 2023. The latest effort to protect artists and their creations is Nightshade, a tool allowing artists to add undetectable pixels into their work that could corrupt an AI's training data, the MIT Technology Review reports. Nightshade's creation comes as major companies like OpenAI and Meta face lawsuits for copyright infringement and stealing personal works without compensation.
University of Chicago professor Ben Zhao and his team created Nightshade, which is currently being peer reviewed, in an effort to put some of the power back in artists' hands. They tested it on recent Stable Diffusion models and an AI they personally built from scratch.
Nightshade essentially works as a poison, altering how a machine-learning model produces content and what that finished product looks like. For example, it could make an AI system interpret a prompt for a handbag as a toaster or show an image of a cat instead of the requested dog (the same goes for similar prompts like puppy or wolf).
Professor Ben Zhao | University of Chicago
Nightshade follows Zhao and his team's August release of a tool called Glaze, which also subtly alters a work of art's pixels but it makes AI systems detect the initial image as entirely different than it is. An artist who wants to protect their work can upload it to Glaze and opt in to using Nightshade.
Damaging technology like Nightshade could go a long way towards encouraging AI's major players to request and compensate artists' work properly (it seems like a better alternative to having your system rewired). Companies looking to remove the poison would likely need to locate every piece of corrupt data, a challenging task. Zhao cautions that some individuals might attempt to use the tool for evil purposes but that any real damage would require thousands of corrupted works.

GM has announced that it will pay $1,400 to owners of 2020-2022 Bolt EVs and EUVs who endured a recall that limited range to 80 percent for a significant period of time, Electrek has reported. It's effectively an upfront payment to customers as part of an expected class action settlement.
"GM is announcing a compensation program for 2020-22 Bolt EV/EUV owners upon installation of the final advanced diagnostic software as part of the original battery recall," a spokesperson wrote in a statement. "Owners are eligible to receive a $1,400 Visa eReward card upon installation. This applies to Bolt EV/EUV owners in the US only. We’re grateful to our customers for their patience and understanding."
Owners must install a "software final remedy" by December 31, 2023 and sign a legal release — those who decline will have to wait for the class action lawsuit to play out. If the settlement ends up being more than $1,400, those who accept the payment will still receive the difference.
It seems like Chevy's Bolt EVs (and larger EUVs that came along in 2021) have never not had problems with their batteries. The 2017-2019 models had serious defects that could cause fires, forcing GM to recall them and install special software, reducing maximum charge levels to 90 percent.
The 2020-2022 models affected by the lawsuit used new battery chemistry with a different issue that could also cause a fire when the car was fully, or nearly fully charged. GM issued a recall for those models as well, installing diagnostic software that would reduce maximum charging levels to 80 percent (cutting range from about 259 miles to 207 miles). The software will eventually either warn customers that their battery pack needs to be replaced, or automatically return the maximum charge to 100 percent.
The problem is, the vehicles needed to reach 6,200 miles of use before the final assessment. That could be years for some buyers, and GM mandated that owners complete the diagnostic by March 2025 in order to qualify for an extended warranty or replacement battery, if needed.
GM announced earlier this year that it was discontinuing the Bolt EV amid the company's shift to the Ultium platform, possibly because it felt the name had been sullied by the battery issues. Following an outcry, though, it backtracked and said that a next-gen Bolt was in the works — showing that people still liked what the Bolt stood for (a practical, cheap EV with decent range) despite the recalls.
Presumably, any potential settlement would cover owners who effectively lost the full and expected use of their vehicle during the period. If you're part of the recall, you should receive a letter soon with more information and a unique PIN to access their site — more information is available here.

NASA has revealed that it has already processed 70.3 grams of rocks and dust collected by the OSIRIS-REx mission from asteroid Bennu. That means the mission has way exceeded its goal of bringing 60 grams of asteroid samples back to Earth — especially since NASA scientists have yet to open the primary sample container that made its way back to our planet in September. Apparently, they're struggling to open the mission's Touch-and-Go Sample Acquisition Mechanism (TAGSAM) and could not remove two of its 35 fasteners using the tools currently available to them.
The scientists are processing the samples inside a specialized glovebox (pictured above) with a flow of nitrogen in order to keep them from being exposed to our atmosphere and any contaminants. They can't just use any implement to break the container's fasteners open either: The tool must fit inside the glovebox, and it also must not compromise the samples' integrity. NASA has sealed the primary container sample for now, while it's developing the procedure to be able to open it over the next few weeks.
If you're wondering where the 70.3 grams of rocks and dust came from, well, NASA collected part of it from the external sample receptacle but outside TAGSAM itself. It also includes a small portion of the samples inside TAGSAM, taken by holding down its mylar flap and reaching inside with tweezers or a scoop. NASA's initial analysis of the material published earlier this month said it showed evidence of high carbon content and water, and further studies could help us understand how life on Earth began. The agency plans to continue analyzing and "characterizing" the rocks and dust it has already taken from the sample container, so we may hear more details about the samples even while TAGSAM remains sealed.

Tinder has rolled out a new feature dubbed “Tinder Matchmaker” that will allow users’ family and friends to access the dating app and make recommendations for potential matches. The matchmakers do not need to have a Tinder profile to view or suggest possible pairings. Hypothetically, that means anyone from your grandmother to your ex-boyfriend could help you select a new profile to match with.
A Tinder user will need to launch a “Tinder Matchmaker session” either directly from a profile card or within the app’s settings. If you see a potential match, you can share a unique link with up to 15 individuals in a 24-hour period. Once a matchmaker gets a link, they can log into Tinder or continue as a guest.
A matchmaker will gain access to profiles they can “like” and if they do, it will appear as a recommendation for the original Tinder user to see. The matchmaker’s abilities are limited though. They can't send messages or actually swipe right on the profiles in question – ultimately, the Tinder user will decide whether or not to match with another.
“For years, singles have asked their friends to help find their next match on Tinder, and now we're making that so easy with Tinder Matchmaker," Melissa Hobley, Tinder's Chief Marketing Officer says on the new feature.
Bumble has a similar offering, where a user can recommend a profile to a friend through a private link that only they can open within the dating app. However, it’s more geared for one-on-one sharing compared to Tinder Matchmaker. Hinge, another key competitor, tried launching a separate Hinge Matchmaker app in 2017. Matchmakers on the Hinge spinoff were supposed to suggest potential pairings based on who the individuals knew personally from Facebook. That secondary app didn't last for Hinge – the app is no longer available.
Tinder’s matchmaker feature is just the latest offering from the company designed to entice more users to engage with the app in new ways. Verification on Tinder got a boost with video selfies, incognito mode finally was introduced earlier this year and the company just started letting Tinder users specify gender pronouns and non-monogamous relationship types.

Instagram is testing a sticker creation feature that will let users make custom stickers from their own photos — and other users’, in some cases — and pop them into Reels or Stories. While Meta has been going all in on prompt-based, AI-generated stickers lately, this tool is something much simpler. It’ll just select the subject of a photo and remove the background, creating a free-floating sticker that can be placed over other content.
Adam Mosseri/ Instagram
Adam Mosseri gave a brief demonstration of how it’ll work in a video shared to his broadcast channel. He also said that, in addition to creating stickers from photos saved on your phone, users will be able to make them from “eligible images you see on Instagram.” Mosseri didn’t share any further details on that, but it suggests users will be able to opt in to making their pictures stickerable.
It’s still just a test and hasn’t rolled out to all users, so we’ll see what that actually looks like in time. The platform last week started testing a new polling feature, too, which will show up in the comments section under feed posts.

Space isn't hard only on account of the rocket science. The task of taking a NASA mission from development and funding through construction and launch — all before we even use the thing for science — can span decades. Entire careers have been spent putting a single satellite into space. Nobel-winning NASA physicist John Mather, mind you, has already helped send up two.
In their new book, Inside the Star Factory: The Creation of the James Webb Space Telescope, NASA's Largest and Most Powerful Space Observatory, author Christopher Wanjek and photographer Chris Gunn take readers on a behind the scenes tour of the James Webb Space Telescope's own journey from inception to orbit. Weaving examinations of the radical imaging technology that enables us to peer deeper into the early universe than ever before with profiles of the researchers, advisors, managers, engineers and technicians that made it possible through three decades of effort. In this week's Hitting the Books excerpt, a look at JWST project scientist John Mather and his own improbable journey from rural New Jersey to NASA.
John Mather is a patient man. His 2006 Nobel Prize in Physics was thirty years in the making. That award, for unswerving evidence of the Big Bang, was based on a bus-sized machine called COBE — yet another NASA mission that almost didn’t happen. Design drama? Been there. Navigate unforeseen delays? Done that. For NASA to choose Mather as JWST Project Scientist was pure prescience.
Like Webb, COBE — the Cosmic Background Explorer — was to be a time machine to reveal a snapshot of the early universe. The target era was just 370,000 years after the Big Bang, when the universe was still a fog of elementary particles with no discernable structure. This is called the epoch of recombination, when the hot universe cooled to a point to allow protons to bind with electrons to form the very first atoms, mostly hydrogen with a sprinkling of helium and lithium. As the atoms formed, the fog lifted, and the universe became clear. Light broke through. That ancient light, from the Big Bang itself, is with us today as remnant microwave radiation called the cosmic microwave background.
Tall but never imposing, demanding but never mean, Mather is a study in contrasts. His childhood was spent just a mile from the Appalachian Trail in rural Sussex County, New Jersey, where his friends were consumed by earthly matters such as farm chores. Yet Mather, whose father was a specialist in animal husbandry and statistics, was more intrigued by science and math. At age six he grasped the concept of infinity when he filled up a page in his notebook with a very large number and realized he could go on forever. He loaded himself up with books from a mobile library that visited the farms every couple of weeks. His dad worked for Rutgers University Agriculture Experiment Station and had a laboratory on the farm with radioisotope equipment for studying metabolism and liquid nitrogen tanks with frozen bull semen. His dad also was one of the earliest users of computers in the area, circa 1960, maintaining milk production records of 10,000 cows on punched IBM cards. His mother, an elementary school teacher, was quite learned, as well, and fostered young John’s interest in science.
A chance for some warm, year-round weather ultimately brought Mather in 1968 to University of California, Berkeley, for graduate studies in physics. He would fall in with a crowd intrigued by the newly detected cosmic microwave background, discovered by accident in 1965 by radio astronomers Arno Penzias and Robert Wilson. His thesis advisor devised a balloon experiment to measure the spectrum, or color, of this radiation to see if it really came from the Big Bang. (It does.) The next obvious thing was to make a map of this light to see, as theory suggested, whether the temperature varied ever so slightly across the sky. And years later, that’s just what he and his COBE team found: anisotropy, an unequal distribution of energy. These micro-degree temperature fluctuations imply matter density fluctuations, sufficient to stop the expansion, at least locally. Through the influence of gravity, matter would pool into cosmic lakes to form stars and galaxies hundreds of millions of years later. In essence, Mather and his team captured a sonogram of the infant universe.
Yet the COBE mission, like Webb, was plagued with setbacks. Mather and the team proposed the mission concept (for a second time) in 1976. NASA accepted the proposal but, that year, declared that this satellite and most others from then on would be delivered to orbit by the Space Shuttle, which itself was still in development. History would reveal the foolishness of such a plan. Mather understood immediately. This wedded the design of COBE to the cargo bay of the unbuilt Shuttle. Engineers would need to meet precise mass and volume requirements of a vessel not yet flown. More troublesome, COBE required a polar orbit, difficult for the Space Shuttle to deliver. The COBE team was next saddled with budget cuts and compromises in COBE’s design as a result of cost overruns of another pioneering space science mission, the Infrared Astronomical Satellite, or IRAS. Still, the tedious work continued of designing instruments sensitive enough to detect variations of temperatures just a few degrees above absolute zero, about −270°C. From 1980 onward, Mather was consumed by the creation of COBE all day every day. The team needed to cut corners and make risky decisions to stay within budget. News came that COBE was to be launched on the Space Shuttle mission STS-82-B in 1988 from Vandenberg Air Force Base. All systems go.
Then the Space Shuttle Challenger exploded in 1986, killing all seven of its crew. NASA grounded Shuttle flights indefinitely. COBE, now locked to Shuttle specifications, couldn’t launch on just any other rocket system. COBE was too large for a Delta rocket at this point; ironically, Mather had the Delta in mind in his first sketch in 1974. The team looked to Europe for a launch vehicle, but this was hardly an option for NASA. Instead, the project managers led a redesign to shave off hundreds of pounds, to slim down to a 5,000-pound launch mass, with fuel, which would just make it within the limits of a Delta by a few pounds. Oh, and McDonnell Douglas had to build a Delta rocket from spare parts, having been forced to discontinue the series in favor of the Space Shuttle.
The team worked around the clock over the next two years. The final design challenge was ... wait for it ... a sunshield that now needed to be folded into the rocket and spring-released once in orbit, a novel approach. COBE got the greenlight to launch from Vandenberg Air Force Base in California, the originally desired site because it would provide easier access to a polar orbit compared to launching a Shuttle from Florida. Launch was set for November 1989. COBE was delivered several months before.
Then, on October 17, the California ground shook hard. A 6.9-magnitude earthquake struck Santa Cruz County, causing widespread damage to structures. Vandenberg, some 200 miles south, felt the jolt. As pure luck would have it, COBE was securely fastened only because two of the engineers minding it secured it that day before going off to get married. The instrument suffered no damage and launched successfully on November 18. More drama came with the high winds on launch day. Myriad worries followed in the first weeks of operation: the cryostat cooled too quickly; sunlight reflecting off of Antarctic ice played havoc with the power system; trapped electrons and protons in the Van Allen belts disrupted the functioning of the electronics; and so on.
All the delays, all the drama, faded into a distant memory for Mather as the results of the COBE experiment came in. Data would take four years to compile. But the results were mind-blowing. The first result came weeks after launch, when Mather showed the spectrum to the American Astronomical Society and received a standing ovation. The Big Bang was safe as a theory. Two years later, at an April 1992 meeting of the American Physical Society, the team showed their first map. Data matched theory perfectly. This was the afterglow of the Big Bang revealing the seeds that would grow into stars and galaxies. Physicist Stephen Hawking called it “the most important discovery of the century, if not of all time.”
Mather spoke humbly of the discovery at his Nobel acceptance speech in 2006, fully crediting his remarkable team and his colleague George Smoot, who shared the prize with him that year. But he didn’t downplay the achievement. He noted that he was thrilled with the now broader “recognition that our work was as important as people in the professional astronomy world have known for so long.”
Mather maintains that realism today. While concerned about delays, threats of cancellation, cost overruns, and not-too-subtle animosity in the broader science community over the “telescope that ate astronomy,” he didn’t let this consume him or his team. “There’s no point in trying to manage other people’s feelings,” he said. “Quite a lot of the community opinion is, ‘well, if it were my nickel, I’d spend it differently.’ But it isn’t their nickel; and the reason why we have the nickel in the first place is because NASA takes on incredibly great challenges. Congress approved of us taking on great challenges. And great challenges aren’t free. My feeling is that the only reason why we have an astronomy program at NASA for anyone to enjoy — or complain about — is that we do astonishingly difficult projects. We are pushing to the edge of what is possible.”
Webb isn’t just a little better than the Hubble Space Telescope, Mather added; it’s a hundred times more powerful. Yet his biggest worry through mission design was not the advanced astronomy instruments but rather the massive sunshield, which needed to unfold. All instruments and all the deployment mechanisms had redundancy engineered into them; there are two or more ways to make them work if the primary method fails. But that’s not the only issue with a sunshield. It would either work or not work.
Now Mather can focus completely on the science to be had. He expects surprises; he’d be surprised if there were no surprises. “Just about everything in astronomy comes as a surprise,” he said. “When you have new equipment, you will get a surprise.” His hunch is that Webb might reveal something weird about the early universe, perhaps an abundance of short-lived objects never before seen that say something about dark energy, the mysterious force that seems to be accelerating the expansion of the universe, or the equally mysterious dark matter. He also can’t wait until Webb turns its cameras to Alpha Centauri, the closest star system to Earth. What if there’s a planet there suitable for life? Webb should have the sensitivity to detect molecules in its atmosphere, if present.
“That would be cool,” Mather said. Hints of life from the closest star system? Yes, cool, indeed.
