  • NASA Rover Detects Potential Signatures of Ancient Microbial Life On Mars
    by BeauHD on 25/06/2026 at 7:00 am

    NASA's Perseverance rover has detected complex organic carbon in ancient Martian mudstones. The measurements were taken by the rover's Sherloc instrument and the organic carbon that was identified was from the Bright Angel outcrop, "a dried-up river that carried water into the planet's Jezero crater billions of years ago," notes The Guardian. From the report: The form of carbon detected, known as macromolecular carbon or MMC, can originate from living organisms. Geological processes can also produce the material, meaning its detection does not amount to proof of past Martian life. Dr Ashley Murphy at the Planetary Science Institute in Arizona said MMC can be found in different settings and types of rocks. "It may originate from biological sources such as fossilized organic matter found in microbial mats and coal," she said, but could also form in reactions between rocks and water or arrive on impacting meteorites. The mudstone rocks from the Bright Angel outcrop caused a stir in 2024 when the Perseverance rover discovered intriguing surface spots and nodules that resemble features produced by fossilized microbes on Earth. When the scientific details were published last year, Sean Duffy, the former acting head of Nasa, said: "This very well could be the clearest sign of life that we've ever found on Mars." [...] The discovery means Nasa rovers have now found organic-bearing mudstones more than 2,000 miles apart on Mars. The others were reported by the Curiosity rover which is exploring the planet's Gale crater. It "indicates that the habitability of Mars, and the availability of organics, may have been widespread across the planet billions of years ago," the authors write in Science Advances.

  • Stripe, Anthropic, and OpenAI Are Backing Effort To Stop Respiratory Infections
    by BeauHD on 25/06/2026 at 3:30 am

    An anonymous reader quotes a report from MIT Technology Review: [T]he payment company Stripe, founded by brothers Patrick and John Collison, says it will fund a new $500 million nonprofit whose goal is preventing both the common cold and the flu. Its eventual aim is to get rid of respiratory viruses altogether. The new organization, called Intercept, will use grants and investments to back prevention approaches, including vaccines, as well as large-scale air-cleaning systems for schools, offices, and other public spaces. In addition to Stripe, other funders include Anthropic, Flu Lab, and the OpenAI Foundation, as well as Bill Gates and several traders at the quantitative investing fund Jane Street Capital, according to an Intercept spokesperson. "I think we treat respiratory infections as a minor nuisance, but have really underweighted the burden that they impose on society," says Nan Ransohoff, the Stripe executive leading the initiative along with Charlie Petty, a venture capitalist who joined Stripe this year. On average, people spend 5% of their lifetime fighting a cold or the flu, according to Ransohoff. Despite that, drug companies put relatively little effort into preventing colds. Part of the problem is that the sniffles are caused by more than 200 different viruses, according to the American Lung Association, with rhinoviruses being the most common culprits. There are so many that it typically doesn't pay to try to stop any one of them with a vaccine. "When pharma companies look at it, it's not as attractive as other things they could work on," says Ransohoff. "So it hasn't attracted the resources." [...] The project takes inspiration from efforts to fight the covid-19 virus, where Veesler's group was among those involved in the speedy development of vaccines, antiviral drugs, and antibodies. According to Ransohoff, Intercept's advisors will include Peter Marks, a former top FDA official, as well as Moncef Slaoui, the pharmaceutical executive who led the US coronavirus vaccine effort, Operation Warp Speed. A key challenge for Intercept will be coming up with ways to counter many viruses at one time. That accounts for the interest in air-cleaning technology, such as using strong ultraviolet light to inactivate viruses. The idea, the group says, is to remove them from the air in the same way municipalities remove impurities from the water supply before it's piped to people's homes.

  • Slate Auto's Radically Simple Electric Truck Starts At $24,950
    by BeauHD on 24/06/2026 at 11:00 pm

    Slate Auto says its stripped-down electric pickup will start at $24,950 before fees, with the base model's estimated range increased from 150 to about 205 miles. The company has started taking preorders on Wednesday. "The aggressive pricing -- half the average cost of a new car in the United States -- puts Slate in position to capture a share of the lowest end of the new car market, which has few gas and fewer electric options these days," reports TechCrunch. From the report: The price reveal comes more than a year after Slate Auto emerged from stealth. Since then, the company has been steadily detailing the extremely basic, transforming EV, which starts as a two-seater pickup truck, but can be modified into a five-seater SUV. The SUV version will start at $29,950, Slate said Wednesday. Slate has said the conversion can be done by professionals or by owners themselves. On Wednesday, it finally showed off some of the first of its "Slate University" how-to videos, which guide people through the steps for doing everything from the SUV conversion to adding headlight covers. Everything else about the truck is bare, though it's customizable. It has hand-crank windows, lacks an infotainment system, and all orders start with the same gray composite material, with no paint options, as Slate plans to let buyers order customizable wraps for the vehicle. That likely helps cut out a major cost center, as factory paint shops can run in the hundreds of millions of dollars. The company did not offer more details about the buying process. Slate has said it "won't have traditional dealerships," and plans to sell directly to customers, similar to other EV companies like Tesla, Rivian, and Lucid Motors.

  • Meta Pauses Employee-Tracking Program Following Internal Data Leak
    by BeauHD on 24/06/2026 at 10:00 pm

    Meta has paused its Model Compatibility Initiative that tracked employee mouse movements, clicks, keystrokes, and screen content to train AI agents, after some of its collected data became accessible to more employees than intended. Meta says it has no evidence the information was improperly accessed and will not restart the program until it is confident in its safeguards. Wired reports: Meta rolled out the Model Compatibility Initiative (MCI) tool in April to US employees. The tool "collects computer inputs such as mouse movements, click locations and keystrokes, as well as screen content," according to workers who have been petitioning against it over privacy, security, and personal liberty concerns. When MCI launched, employees couldn't opt out, but that changed to a limited degree after workers protested. Meta executives have repeatedly defended the data-gathering project, saying it was necessary to train AI systems to operate computer software the way humans do and that employees were the best examples for the artificial intelligence to learn from. On Monday, a Meta engineer issued an internal security notice stating that databases filled with information gathered by MCI had been exposed to anyone inside the company. A former employee actively involved in pushing back against MCI describes the lapse as "a mess" -- and one that employees had expected would occur. "When workers raised concerns, leadership doubled down and failed to acknowledge the risks workers raised about the safety and privacy of worker and customer data," the person says. "Leadership has clearly created an authoritarian environment where workers are no longer respected or heard." But after critical comments poured into internal forums on Monday expressing frustration about the security issue, Meta shocked some of its staff by pausing MCI altogether, telling WIRED about the development several hours before announcing it to employees. A few workers told WIRED they were confused in the meantime because the tool was continuing to run on their laptops. Late on Monday, Stephane Kasriel, a Meta vice president overseeing AI research, announced the pause and told staff that the security issue had been discovered on June 18 and addressed within four hours. But the initial fix didn't stick and access to the data had to be further locked down. The issue made "some MCI-derived data" accessible to more people than intended, he wrote, without elaborating.

  • GTA VI Is a Worrying Sign For the Future of Physical Games
    by BeauHD on 24/06/2026 at 9:00 pm

    Rockstar Games has revealed the price of Grand Theft Auto VI to be $79.99, and confirmed that the physical versions of the game won't include a disc. Instead, they'll contain a one-time download code when it launches November 19. "Not only is that a disappointing decision for people who like to own physical games, but given the scale of the next GTA, it also sets a bad precedent for the rest of the industry," reports The Verge. From the report: There are a lot of advantages to buying digital. You can start a download from your couch. You can store multiple games on one hard drive so you don't have to get up to play something else. Storefronts like Steam or the PlayStation Store don't run out of inventory of the newest game you're interested in, and you can often get games at a cheaper price thanks to frequent sales. But it's becoming increasingly clear that digital ownership has significant disadvantages, too. If a game you don't own digitally is removed from a storefront, whether that's for things like licensing, artificially limited availability, or even the store eventually closing down, your only option is to hope you can find a physical version. If your account on a platform is banned, even if that ban isn't warranted, you might be locked out of your digital library with no way to play those games unless you buy them again or hope your account gets restored. You can't sell or trade digital games you've purchased, and while there are ways to share digital games, they require some work and are usually intended just for families. It's also much harder to preserve digital games because they only "exist" on the hard drive of a console, PC, or device they were downloaded to. This is an issue across many industries, not just console games; there are multiple examples of things like mobile games and streaming shows becoming lost for good when they don't have a physical version. Without physical versions, you also can't find a used version of a game at a garage sale or a local game shop. It's unclear whether Rockstar will ever release a physical version of the game. As for why, The Verge suspects the decision was made in part to prevent leaks; "by only being available digitally, Rockstar can ensure that GTA VI unlocks at the same exact time for everyone." "The digital-only choice might also indicate that the game has a massive file size that's too big for PlayStation and Xbox game discs." Read more of this story at Slashdot.

  • OpenAI Unveils First Chip As Part of Broadcom Deal
    by BeauHD on 24/06/2026 at 8:00 pm

    OpenAI and Broadcom have unveiled Jalapeno, OpenAI's first custom AI chip, designed primarily to handle inference for ChatGPT and other services. It's a major step in OpenAI's plan to "build the full stack behind its models and products," says OpenAI. "By designing more of the stack ourselves, we can serve more intelligence with greater efficiency and keep pushing advanced AI toward broader access." CNBC reports: The chip with Broadcom is an ASIC, which industry experts say is less flexible than Nvidia's GPU, but is also less expensive and can be designed for specific AI tasks. OpenAI said that it designed the chip in nine months, and that it also crafted large parts of the computer system where it will be used. The companies are calling the chip an "Intelligence Processor" and describe it as the first "AI accelerator" in a platform they're building "to make advanced AI faster, more reliable, and more accessible to more people." [...] A physical sample of the new chip will be delivered to OpenAI on Wednesday. The companies said they're aiming for initial deployment of the Jalapeno chips by the end of 2026, "expanding in the years ahead." Read more of this story at Slashdot.
