  • Microsoft Gives Task Manager Another Task: Watching AI Workloads
    by BeauHD on 21/08/2026 at 11:00 am

    Microsoft is expanding Windows Task Manager to show per-process NPU and GPU neural-engine usage, giving users more visibility into which apps are consuming hardware for AI workloads. The Register reports: The Processes tab can show NPU use alongside CPU and GPU activity, while the Performance tab displays overall utilization. [...] Microsoft was keen to point out the metrics that can be monitored. "As AI workloads become more common on Windows devices, visibility into NPU and GPU neural engine utilization can help you make better-informed decisions," the company said. "With the latest Task Manager improvements, you can monitor AI processing activity alongside CPU, memory, storage, and networking data from a familiar interface."

  • China Is About to Launch Its Most Ambitious Moon Mission Yet
    by BeauHD on 21/08/2026 at 7:00 am

    China's Chang'e 7 mission is set to launch for the moon's south pole, where it will attempt the first-ever landing directly at the pole and search the region's dark craters for water ice. "It's an amazing mission," says Norbert Schorghofer, a Hawaii-based senior scientist at the Planetary Science Institute. "There has never been a landed mission to find water [on the moon]." If successful, China "will be the leader in lunar science," Schorghofer adds. Scientific American reports: Chang'e 7, China's seventh moon mission, is scheduled to launch on a Long March 5 rocket from the coastal Wenchang Space Launch Site on the island of Hainan, with the launch window opening on the morning of August 24 local time (the evening of August 23 EDT). The mission includes an orbiter, as well as a lander, which totes a rover and a novel "hopping" robot. The spacecraft will take up to six days to reach lunar orbit, where it will then spend two months preparing for a November landing meant to be a near bull's-eye on the lunar south pole. The mission also includes equipment from several international partners, highlighting China's growing global influence -- both on and off Earth. The mission's lunar target is Shackleton Crater, a 21-kilometer-wide (13-mile-wide) pit with a rim that grazes the moon's south pole. No other spacecraft has ever landed so close. That proximity should allow Chang'e 7 to prospect for water ice trapped in smaller depressions near Shackleton that, because of the moon's tilt, never see sunlight and have temperatures just a few dozen degrees above absolute zero. "There are big reservoirs of ice water at the poles," says Simone Dell'Agnello, a physicist at Italy's National Institute for Nuclear Physics. No one knows, however, just how big those reservoirs are or what their actual distribution is across the lunar south pole's crater-pocked desolation. And because that ice might be used as for manufacturing rocket fuel or to make potable water for thirsty astronauts, answering those questions is key for the U.S.'s and China's competing plans to construct crewed lunar outposts.

  • Are You Sure You Want a Car With a Giant Touch Screen?
    by BeauHD on 21/08/2026 at 3:30 am

    RAMageddon could soon push car prices higher as modern vehicles rely on ever more RAM and powerful centralized computers to run everything from infotainment to driver-assistance systems. Analysts cited by The Atlantic estimate the shortage could add a few percentage points to vehicle prices, which might not sound like much, but could potentially translate to around $2,000 on a $50,000 vehicle. The broader shift toward software-heavy vehicles could also make used cars even less affordable. An anonymous reader quotes an excerpt from the report: Just like laptops, cars depend on microprocessors and RAM, or random-access memory, to run all of their computations. "There's just a baseline level of tech, and thus a baseline level of cost, required of every vehicle," Karl Brauer, the executive analyst at iSeeCars, an automotive-research platform, told me. Technology is a major reason the average price of a new car in the U.S. has reached some $50,000, and that was before RAM became one of the most prized commodities in the world. AI companies are snatching up as much memory as possible for their data centers, causing a RAM shortage that has significantly raised the prices of phones, laptops, and just about any consumer-electronic device. Cars are next. [...] Over the next year, the memory shortage -- sometimes known as RAMageddon -- will likely raise vehicle prices by a few percentage points, on average, [said Sam Abuelsamid, an analyst at Telemetry and a former automotive engineer]. The relative amount would be smaller than the shocking double-digit jumps for gaming consoles and MacBooks but in some ways more significant: A 4 percent price hike for cars amounts to some $2,000 on average. Cars with those centralized computers will be affected the most, but no vehicle will be spared. "Even if you don't need the high-end chips, you're going to pay more even for the low-end chips just because of the supply constraint," Abuelsamid said. On a recent earnings call, Ford's chief financial officer said that the company had paid $1 billion in higher materials costs due to the memory shortage and inflation. GM and Volkswagen, too, have noted rising chip costs to investors. (Ford and GM did not respond to a request for comment. A spokesperson for Volkswagen told me that the company has "recognized an increased demand for memory chips, primarily driven by growing requirements in other industries," and that in recent years, Volkswagen has taken measures to "mitigate supply risks.") RAMageddon is poised to last for several years, but the consequences for car buyers may be permanent. Consider what happened during the pandemic, when supply-chain disruptions and rising demand for electronics produced a major chip shortage. Nearly every major car company had to slash production because they simply couldn't procure enough chips, and shifted their focus to selling higher-end and higher-profit vehicles. Potential customers already willing to spend six figures on a car are much less likely to care about a 5 or 10 percent price hike, [said Ivan Drury, the director of insights at Edmunds]. Even now, car companies are continuing to focus on selling more profitable models. Since the pandemic, the average price of a new vehicle has jumped $11,000. The AI-fueled chip crisis could play out more severely. The average price of a new car could, before long, jump to $60,000 and beyond. These rising costs are making cars even more similar to computers and all of the software they run: Perhaps in an effort to mitigate higher prices, some automakers are also introducing in-car advertisements and putting certain features, such as heated seats, behind a paywall. As cars have morphed into computers, the inevitable next step is for automakers to behave like modern tech companies. Read more of this story at Slashdot.

  • China's YouTube Rival Bilibili Is Going Global
    by BeauHD on 20/08/2026 at 11:00 pm

    Bilibili, often described as China's answer to YouTube, is relaunching its international app and preparing an English-language site as part of a broader push into the U.S., Europe, Japan, and other markets. The company is courting Western creators like MrBest, hiring community and moderation staff globally, and building tools for brand partnerships. Semafor reports: The revamped international app no longer requires identity verification -- meaning users can sign up without having to provide a passport or ID document, which were long required of overseas users on its main Chinese platform, according to what appears to be a newly created account on X marketing the platform to global creators. "Yes bilibili is going global," the account wrote, adding that content-wise, the US and Chinese sites will be the same. In a document recently shared in a Discord chat for Bilibili creators, the company pitched itself as a place for influencers to make money and connect with "Gen Z Coded, affluent and well-educated" users. A marketplace for international users to connect with brands for sponsored content is "in development," according to the presentation. The deck also showed creators how to post videos on its Chinese website, adding that an English version is "coming soon. We are working hard." Read more of this story at Slashdot.

  • Watching TikTok Videos and Instagram Reels Deactivates the Brain's Cognitive Control Network
    by BeauHD on 20/08/2026 at 10:00 pm

    An anonymous reader quotes a report from RathBiotaClan: Millions of people finish short video after short video every day; a new brain-scan study shows that the very act of finishing a clip they like temporarily quiets the brain regions that normally help them stay focused and weigh longer-term goals. When people watch a short video they enjoy enough to finish, two brain regions involved in cognitive control show significant deactivation. That is the central finding of a new study from Zhejiang University, published in NeuroImagein January 2026. Using functional MRI alongside proton magnetic resonance spectroscopy (H-MRS), the research team examined 56 young adults while they freely watched short video clips inside an MRI scanner. Both the dorsal anterior cingulate cortex (dACC) and the dorsolateral prefrontal cortex (dlPFC) showed reduced activity specifically when participants watched clips they liked enough to view to completion. Cognitive control helps people balance immediate pleasures against longer-term goals, and impairments in this system are linked to conditions such as depression, anxiety, ADHD, and addiction. Short-video platforms present rapid, algorithmically curated streams that are built for continuous, low-effort consumption. Prior behavioral research has tied both internet addiction and smartphone addiction to weaker self-control, and separate neuroimaging work has documented disruptions to reward and cognitive-control circuits in people with behavioral addictions. Despite this, few studies had directly tested whether the act of watching entertaining short videos itself suppresses the brain's cognitive control regions. The Zhejiang University team set out to answer that question, along with a second one: what neurochemical factors might explain why this suppression varies from person to person?

  • Ukrainian Publishers Call For Support After Russian Attacks Destroy 10 Million Books
    by BeauHD on 20/08/2026 at 9:00 pm

    Russian attacks on Ukrainian publishing infrastructure in July and August destroyed roughly 10 million books, which equates to about 30% of Ukraine's annual book output. The Ukrainian Book Institute is warning of a potential "collapse of the entire book ecosystem" and is calling for international financial and industry support to help publishers, printers, and distributors recover. The Guardian reports: A major attack on August 1 hit warehouses belonging to the RNK-Ranok publishing group in Kharkiv, destroying approximately 8m books, following July attacks in Kyiv which led to the loss of more than 1.5m books. In all, the recent attacks have led to the destruction of approximately 30% of the volume of books produced annually in Ukraine. The RNK-Ranok logistics centre, which stores books for the company's many imprints, is also the distribution centre for the national bookselling chain KnyhoLand, which runs 51 shops and several websites. Along with the estimated 8m books lost, a further 600,000 school textbooks were destroyed. The total loss has been preliminarily estimated at almost 1bn hryvnias (16.5m eueros). "At this stage, we face the risk of the collapse of the entire book ecosystem," said Oleksandra Koval, director of the Ukrainian Book Institute. The institute is asking for donations to support Ukrainian publishers, and is calling on the international publishing community to work with Ukrainian publishers and raise awareness about Russian attacks on Ukrainian culture. On August 16, a Russian attack on Kyiv led to a fire breaking out at the Pochaina book market, destroying several rows of stalls, books and vendors' property. The Pochaina market, founded in 1997, was once one of Ukraine's largest book markets, with hundreds of stalls and books from more than 120 publishers. The institute said the book industry was of "strategic importance" to Ukraine, preserving and promoting Ukrainian culture and giving the country's voice a platform at home and abroad. [...] The institute also called for an end to cooperation with Russian publishers and literary agencies, saying that solidarity with Ukrainian publishers was crucial to preserving cultural heritage that Russia was "deliberately trying to destroy."
