      Have physicists finally discovered glueballs? New evidence points to yes.

      news.movim.eu / ArsTechnica • 12 August 2026

    Physicists with the Beijing Spectrometer III (BES III) experiment have uncovered convincing new evidence of the existence of so-called glueballs , an elusive composite particle made entirely of gluons predicted by quantum theory. The results appeared in a preprint posted to arXiv last month and were also presented last week at the International Conference on High Energy Physics (ICHEP).

    All the stuff we see around us is made up of quarks held together by gluons (carriers of the nuclear strong force) to form protons and neutrons, which comprise the core of every single atom. The Higgs boson , discovered in 2012 after decades of searching, was widely touted as the final missing piece of the Standard Model of Particle Physics. But there are still plenty of unanswered questions, including whether or not glueballs really exist. They should, if the Standard Model is correct; they're a direct prediction of quantum chromodynamics, i.e., the theory of the strong nuclear force. There should even be several kinds of glueballs.

      Twitch content has trained Amazon AI for years, but users can opt out now

      news.movim.eu / ArsTechnica • 12 August 2026

    Twitch now lets users opt out of Amazon's use of content from their channels to train Amazon's "generative AI content models." The change, announced today, comes more than two years after a company executive confirmed that Amazon was using Twitch content for AI training.

    In an updated support page , Twitch confirms that users must opt out if they don’t want their “streams, VODs, clips, stream chats, and pictures and text on your channel [to] be used in future training of a model developed by Amazon whose purpose is to generate or synthesize text, audio, images, or video.”

    To opt out, users must go to the proper settings at www.twitch.tv/settings/security .

      Trump sued over "brazen" scheme to sell Truth Social API access for $100K a month

      news.movim.eu / ArsTechnica • 12 August 2026

    President Trump was sued by nonprofit news groups today over Truth Social's "Truth API" that sells real-time access to posts from Trump and other top users of the social network. Trump is profiting from selling preferential access to government information, the lawsuit said.

    Trump's social media company this month started charging customers up to $100,000 per month for the earliest access to posts that can have immediate impacts on financial markets. The first customers are mostly high-frequency trading firms that could benefit financially from getting official government news milliseconds before others.

    "This scheme is profoundly corrupt. The President stands to gain financially by giving 'market-moving' government information to those who are willing and able to pay his personal company," the lawsuit said.

      US boosts drone surveillance as flesh-eating screwworms spread in Texas

      news.movim.eu / ArsTechnica • 12 August 2026

    Hundreds of US government drones have switched from border surveillance to a different surveillance mission this summer—looking for signs of screwworm infestations in wild animals and livestock herds.

    The flesh-eating New World Screwworm is the parasitic larva that emerges from eggs laid by flies in the open wounds or body openings of warm-blooded animals and humans, with untreated cases potentially leading to severe injury or death. Since the first screwworm cases were detected in South Texas in June, the US Department of Agriculture and US Customs and Border Protection have been conducting “one of the most extensive animal-health surveillance operations in the country,” according to the USDA in social media posts on platforms like X and Facebook on August 10.

    The effort involves at least 200 drones owned by the Department of Homeland Security, which includes the Customs and Border Protection (CBP) agency. The USDA has described performing more than 1,000 drone flights and surveying more than 22,000 animals so far.

      Two hydrogen-burning engines powered this car to a new land speed record

      news.movim.eu / ArsTechnica • 12 August 2026 • 1 minute

    It's been far too long since I've been able to report a new land speed record. For a while, it looked like Bloodhound might have been able to make good on its 1,000 mph (1,609 km/h) attempt, but then the money ran out . As a result, Thrust SSC's two-way average of 763.6 mph (1,229 km/h), set in 1997, remains the fastest anyone has ever driven a wheeled vehicle over a timed mile . But yesterday, on the Bonneville Salt Flats in Utah, a new record was set by the JCB Hydromax for hydrogen-powered cars.

    JCB is a UK-based manufacturer of heavy industrial and agricultural equipment—think diggers, loaders, backhoes, tractors, and so on. And as JCB is based in the UK, it doesn't have the luxury of being able to ignore carbon emissions targets; it has to have alternatives to diesel engines. For some products, that means switching to batteries, but the company has also been working with hydrogen. At first, that meant fuel cells, but after developing prototypes, JCB concluded the tech was too expensive and too fragile for life on the farm or the construction site. Instead, in 2020, the company started developing its own hydrogen combustion engine.

    The idea of burning hydrogen in an internal combustion engine has been tried before with little success. For example, in 2006, BMW modified a naturally aspirated V12 engine in a 7 Series to run on hydrogen, which it did, but with 60 percent of the power and five times the fuel consumption compared to gasoline. More recently, Toyota's president Akio Toyoda has been among the drivers of an experimental hydrogen-burning Toyota Corolla in some Japanese endurance races . In this case, Toyota started with the GR Corolla's turbocharged three-cylinder engine; the forced induction from the turbocharger made up somewhat for the reduced energy density of hydrogen.

      US tries to override New York gambling laws, orders Kalshi to keep operating

      news.movim.eu / ArsTechnica • 12 August 2026

    The Trump administration is trying to stop New York from enforcing its gambling laws against Kalshi, and yesterday said it ordered the prediction market to continue operating in the state.

    The Commodity Futures Trading Commission (CFTC) announced that it exercised its emergency authority in response to a "market emergency." The CFTC said it acted "to ensure market stability" and "ordered the exchange to continue to operate in accordance with the Commodity Exchange Act’s Core Principles." The Trump administration took the action after a request from Kalshi.

    The market emergency alleged by the CFTC is that New York Attorney General Letitia James sued Kalshi on July 31. James' lawsuit seeks a court order to permanently enjoin Kalshi "from operating an unlawful gambling business" in the state. The lawsuit also demands that Kalshi "make full restitution to customers who have engaged in betting" and pay financial penalties.

      Booksellers suspect AI firms are buying and then destroying rare books

      news.movim.eu / ArsTechnica • 12 August 2026

    If you can truly appreciate an old book—and maybe even marvel at how its fragile, yellowing pages contain some of the earliest ways that people tried to make sense of the world around them—then headlines about tech companies destroying books to train AI likely torture a tender part of your soul.

    It’s indeed depressing to imagine piles of book spines waiting to be fed into wood chippers while torn-out pages are cropped, scanned, and trashed. But that’s the cheapest and easiest way to scan books as fast as possible, and AI companies are in a race to advance their models by training on the kind of engaging, high-quality, long-form texts that can only be found in books. So book lovers fear it’s likely that the practice is happening on a grander scale than is currently being reported and that some physical copies of books will be lost forever.

    What makes this destruction extra painful, though, is that it doesn’t have to be this way.

      Google reveals 2026 hardware lineup: Pixel 11, Pixel Watch 5, and Pixel Tag

      news.movim.eu / ArsTechnica • 12 August 2026 • 1 minute

    Google has revealed its Pixel phone hardware for 2026, and you won't be surprised. The Pixel 11 series looks a lot like last year's lineup , featuring an evolution of the design Google adopted with the Pixel 9. There are some minor tweaks, a few new hardware goodies, and yes, even more Gemini-powered AI. The new phones are joined by an updated Pixel Watch 5 with much the same story, as well as Google's first in-house tracker device, the Pixel Tag. And you can place orders for all of Google's new hardware today.

    The Pixel 11 series is clearly the star of the show—you might even call it the highlight… erm, sorry, HiLight . Just as the leaks predicted , Google's most notable hardware innovation for the 2026 Pixel phones is the return of the notification LED (sort of).

    HiLight is available on the Pro phones, so the base model Pixel will remain unilluminated. HiLight consists of a ring of RGB LEDs inside the flash assembly on the back of the phone. It lights up when you're talking to Gemini, so you don't have to look at the screen of your phone to know you've been heard or that the AI is working. Thus, it makes the most sense when the phone is lying face down.

      Researchers found a way to hijack devices through Zoom screen sharing

      news.movim.eu / ArsTechnica • 12 August 2026 • 1 minute

    As AI models gain advanced capabilities to find vulnerabilities in software, develop ways to exploit them , and even carry out autonomous hacking sprees , researchers offered a sobering new example on Tuesday, disclosing vulnerabilities in the video conferencing platform Zoom that could have been exploited to take over targets’ devices. Anyone on a call that involved screen sharing, whether participants or the host, would have been vulnerable to a silent attack that could be carried out with no indication and no interaction from the victim.

    Researchers from the digital defense firm A Security say the bug was discovered in early June using publicly available AI models, and that it took fewer than 20 prompts to uncover the vulnerabilities and create a working attack. Zoom issued a security advisory on Tuesday, including details about fixes the company has already begun rolling out to address the flaws, which affected devices running all operating systems that Zoom supports—Windows, macOS, Linux, iOS, and Android.

    “What is interesting for us and what we believe is dangerous is the democratization of these capabilities—the barrier to entry is dropping rapidly,” A Security cofounder Omer Gull told WIRED ahead of the disclosure. “Before it would have taken a team of five people maybe six months with a lot of refining and iteration to find this. Now people can reach the same results with under 20 prompts. And Zoom is an important type of target because people assume trust when using it. They don’t see it as a threat.”
