New Mars Orbiter Manuever Challenges Theory: That May Not Be an Underground Lake on Mars14:04 In 2018 researchers claimed evidence of a lake beneath the surface of Mars, detected by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument (or Marsis for short). But new Mars observations "are not consistent with the presence of liquid water in this location and an alternative explanation, such as very smooth basal materials, is needed." Phys.org explains Aboard the Mars Reconnaissance Orbiter, the Shallow Radar (SHARAD) uses higher frequencies than MARSIS. Until recently… How An MIT Student Awed Top Economists With His AI Study - Until It All Fell Apart10:50 In May MIT announced "no confidence" in a preprint paper on how AI increased scientific discovery, asking arXiv to withdraw it. The paper, authored by 27-year-old grad student Aidan Toner-Rodgers, had claimed an AI-driven materials discovery tool helped 1,018 scientists at a U.S. R&D lab. But within weeks his academic mentors "were asking an unthinkable question," reports the Wall Street Journal. Had Toner-Rodgers made it all up? Toner-Rodgers's illusory success seems in part thanks to the dyna… 'We Could've Asked ChatGPT': UK Students Fight Back Over Course Taught By AI7:07 An anonymous reader shared this report from the Guardian: James and Owen were among 41 students who took a coding module at the University of Staffordshire last year, hoping to change careers through a government-funded apprenticeship programme designed to help them become cybersecurity experts or software engineers. But after a term of AI-generated slides being read, at times, by an AI voiceover, James said he had lost faith in the programme and the people running it, worrying he had "used up … Napster Said It Raised $3 Billion From a Mystery Investor. But Now the 'Investor' and 'Money' Are Gone3:56 An anonymous reader shared this report from Forbes: On November 20, at approximately 4 p.m. Eastern time, Napster held an online meeting for its shareholders; an estimated 700 of roughly 1,500 including employees, former employees and individual investors tuned in. That's when its CEO John Acunto told everyone he believed that the never-identified big investor — who the company had insisted put in $3.36 billion at a $12 billion valuation in January, which would have made it one of the year's bi… New Research Finds America's Top Social Media Sites: YouTube (84%) Facebook (71%), Instagram (50%)1:49 Pew Research surveyed 5,022 Americans this year (between February 5 and June 18), asking them "do you ever use" YouTube, Facebook, and nine of the other top social media platforms. The results? YouTube 84% Facebook 71% Instagram 50% TikTok 37% WhatsApp 32% Reddit 26% Snapchat 25% X.com (formerly Twitter) 21% Threads 8% Bluesky 4% Truth Social 3% An announcement from Pew Research adds some trends and demographics: The Center has long tracked use of many of these platforms. Over the past few year… Was the Moon-Forming Protoplanet 'Theia' a Neighbor of Earth?0:46 Theia crashed into earth and formed the moon, the theory goes. But then where did Theia come from? The lead author on a new study says "The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner Solar System. Earth and Theia are likely to have been neighbors." Though Theia was completely destroyed in the collision, scientists from the Max Planck Institute for Solar System Research led a team that was able to measure the ratio of tell-tale isotope… Cryptologist DJB Criticizes Push to Finalize Non-Hybrid Security for Post-Quantum Cryptography23:42 In October cryptologist/CS professor Daniel J. Bernstein alleged that America's National Security Agency (and its UK counterpart GCHQ) were attempting to influence NIST to adopt weaker post-quantum cryptography standards without a "hybrid" approach that would've also included pre-quantum ECC. Bernstein is of the opinion that "Given how many post-quantum proposals have been broken and the continuing flood of side-channel attacks, any competent engineering evaluation will conclude that the best w… Google Revisits JPEG XL in Chromium After Earlier Removal22:39 "Three years ago, Google removed JPEG XL support from Chrome, stating there wasn't enough interest at the time," writes the blog Windows Report. "That position has now changed." In a recent note to developers, a Chrome team representative confirmed that work has restarted to bring JPEG XL to Chromium and said Google "would ship it in Chrome" once long-term maintenance and the usual launch requirements are met. The team explained that other platforms moved ahead. Safari supports JPEG XL, and Win… Mozilla Announces 'TABS API' For Developers Building AI Agents21:35 "Fresh from announcing it is building an AI browsing mode in Firefox and laying the groundwork for agentic interactions in the Firefox 145 release, the corp arm of Mozilla is now flexing its AI muscles in the direction of those more likely to care," writes the blog OMG Ubuntu: If you're a developer building AI agents, you can sign up to get early access to Mozilla's TABS API, a "powerful web content extraction and transformation toolkit designed specifically for AI agent builders"... The TABS A… One Company's Plan to Sink Nuclear Reactors Deep Underground19:59 Long-time Slashdot reader jenningsthecat shared this article from IEEE Spectrum: By dropping a nuclear reactor 1.6 kilometers (1 mile) underground, Deep Fission aims to use the weight of a billion tons of rock and water as a natural containment system comparable to concrete domes and cooling towers. With the fission reaction occurring far below the surface, steam can safely circulate in a closed loop to generate power. The California-based startup announced in October that prospective customers… Could High-Speed Trains Shorten US Travel Times While Reducing Emissions?18:56 With some animated graphics, CNN "reimagined" what three of America's busiest air and road travel routes would look like with high-speed trains, for "a glimpse into a faster, more connected future." The journey from New York City to Chicago could take just over six hours by high-speed train at an average speed of 160 mph, cutting travel time by more than 13 hours compared with the current Amtrak route... The journey from San Francisco to Los Angeles could be completed in under three hours by hi… Microsoft and GitHub Preview New Tool That Identifies, Prioritizes, and Fixes Vulnerabilities With AI17:52 "Security, development, and AI now move as one," says Microsoft's director of cloud/AI security product marketing. Microsoft and GitHub "have launched a native integration between Microsoft Defender for Cloud and GitHub Advanced Security that aims to address what one executive calls decades of accumulated security debt in enterprise codebases..." according to The New Stack: The integration, announced this week in San Francisco at the Microsoft Ignite 2025 conference and now available in public … Engineers are Building the Hottest Geothermal Power Plant on Earth - Next to a US Volcano16:48 "On the slopes of an Oregon volcano, engineers are building the hottest geothermal power plant on Earth," reports the Washington Post: The plant will tap into the infernal energy of Newberry Volcano, "one of the largest and most hazardous active volcanoes in the United States," according to the U.S. Geological Survey. It has already reached temperatures of 629 degrees Fahrenheit, making it one of the hottest geothermal sites in the world, and next year it will start selling electricity to nearb… How the Internet Rewired Work - and What That Tells Us About AI's Likely Impact23.listopadu "The internet did transform work — but not the way 1998 thought..." argues the Wall Street Journal. "The internet slipped inside almost every job and rewired how work got done." So while the number of single-task jobs like travel agent dropped, most jobs "are bundles of judgment, coordination and hands-on work," and instead the internet brought "the quiet transformation of nearly every job in the economy... Today, just 10% of workers make minimal use of the internet on the job — roles like butc… Microsoft Warns Its Windows AI Feature Brings Data Theft and Malware Risks, and 'Occasionally May Hallucinate'23.listopadu "Copilot Actions on Windows 11" is currently available in Insider builds (version 26220.7262) as part of Copilot Labs, according to a recent report, "and is off by default, requiring admin access to set it up." But maybe it's off for a good reason...besides the fact that it can access any apps installed on your system: In a support document, Microsoft admits that features like Copilot Actions introduce " novel security risks ." They warn about cross-prompt injection (XPIA), where malicious cont… |
