  • First Thorium Nuclear Clocks Begin to Tick
    by BeauHD on 09/10/2026 at 3:00 am

    Researchers in Vienna and Beijing have independently built the first nuclear clocks based on oscillations inside thorium nuclei, marking a major milestone for a field that could eventually produce highly portable, ultra-precise timekeepers. The clocks are already precise enough to lose only about a second over millions of years. The New York Times reports: The first nuclear clocks are not going to immediately supplant the worldwide network of atomic clocks, whose steady ticking we rely on for GPS and the definition of a second. Nor have they captured the record for most precise timepiece; the best atomic clocks are about 10,000 times more reliable and would take more than 100 billion years to lose one second. But nuclear clocks hold a bevy of potential advantages over existing atomic clocks. One day, they could be more reliable than the leading atomic versions, and nuclear clocks could be made more portable. They even hold the ability to search for certain kinds of dark matter -- the invisible stuff whose clumps make up 83 percent of the matter in the universe. If a particle of dark matter passed through the thorium nuclei, it could register as a wobble in the nuclear clock's otherwise steady ticktock. The findings have been published in the journal Nature.

  • US Bars Microsoft, Adobe, and Major IT Firms From Green Card Program
    by BeauHD on 08/10/2026 at 11:00 pm

    An anonymous reader quotes a report from TechCrunch: The Trump administration is suspending Microsoft, Adobe, and several other technology companies from a program that helps skilled foreign workers obtain permanent residency in the United States, accusing the companies of fraud. "Our message to Microsoft is: You're a great American company, but you've got to hire great American workers," U.S. Vice President JD Vance said in a news conference on Thursday, Reuters reported. The other firms being suspended from the program include Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro. Secretary of Labor Keith Sonderling said the government would not accept any new or pending permanent labor certification applications involving these companies. H-1B visas are designed for highly skilled positions that employers may struggle to fill with qualified U.S. workers. Tech companies are among the largest users of the program, with nearly three-quarters of approved visas going to workers from India, according to The Associated Press. Vance also said during the news conference that the administration would investigate nine universities, including Harvard, Yale, and Stanford, over allegations they're abusing a program that allows international students to come to the U.S. and were using the program to undermine wages for American workers. "We believe in the strength and talent of the American workforce," a Microsoft spokesperson said in a statement. "That is why the vast majority of Microsoft employees in the United States are Americans. We look forward to providing the Administration with additional information. For example, of the approximately 6,000 H-1B visa applications we submitted in the last fiscal year, 80% percent were to extend or change the status of existing Microsoft employees." "These were not to hire new people. The remaining filings for new employees were for individuals already legally in the United States who decided to come work for us, and they equal only 1% of our U.S. workforce. They are not new arrivals to our country." Read more of this story at Slashdot.

  • Emmy Awards Leave Broadcast TV For Prime Video
    by BeauHD on 08/10/2026 at 7:00 pm

    Amazon Prime Video will become the exclusive global home of the Emmy Awards under a six-year deal beginning in 2027, the Television Academy announced on Tuesday. The Emmys will stream live for free to viewers in more than 240 countries and territories without requiring a Prime subscription. From the report: In the release, Prime Video was named as the "permanent home" for the Emmys, in contrast to the rotating agreement in place years prior. The switch ends the traditional "wheel-deal" setup to broadcast the awards, where ABC, CBS, NBC and Fox took turns hosting the Emmys each year. The system has been in place since at least 1994, with the most recent eight-year contract expiring this year. "Television has never been more global, and the Emmys should be a celebration that the world can share," Television Academy chair Cris Abrego said in a statement. "Having a dedicated home with Prime Video allows us to build on that legacy with unprecedented global reach and a broader commitment to the Television Academy and our mission throughout the year."

  • Female AI Agents 'Paid' Less Than Males, Study Finds
    by BeauHD on 08/10/2026 at 3:00 pm

    Ancient Slashdot reader williamyf writes: If you thought the gender pay gap was not real, and that there were no biases in the workplace, think again: A recent study from the University of Limerick found that, in a VR office setting, AI agents -- not even humanoid robots -- that presented themselves as "male" were paid more per task and perceived as more "human-like" than their "female" counterparts, even though both were using the same underlying technology (LLM model, agent, guardrail, and harness). The pay gap was approximately 10%. The study was conducted with 189 people. Small sample, but still, food for thought. Read more of this story at Slashdot.

  • Chrome 155 Ships Decoding Support For JPEG XL
    by BeauHD on 08/10/2026 at 11:00 am

    Google has released Chrome 155 with support for decoding JPEG XL images, a format that offers 30-50% better compression than JPEG along with lossless compression, JPEG transcoding, HDR, animation, and progressive decoding. From a blog post: We expect that JPEG XL is most helpful for high-fidelity or lossless compression, especially of photographic images or in cases in which fine-grained progressive decoding is preferred. In this post, we share why we brought JPEG XL to Chrome, how we used Rust to ensure memory safety first, the extensive performance work that makes it fast, and what the journey tells us about developer feedback and the web standards ecosystem. [...] With JPEG XL officially landing in Chrome, the web becomes faster, richer, and safer. We encourage developers, content creators, and platform owners to start using .jxl images and animations in their pipelines. Try it out, file bugs, and help us continue building a faster and safer web for everyone. Read more of this story at Slashdot.

  • OpenAI Unleashes Hundreds More Math Results Upon a Field Already In Shock
    by BeauHD on 08/10/2026 at 7:00 am

    OpenAI says an unreleased internal model has produced 372 results that either resolve or make substantial progress on open problems in mathematics and theoretical computer science. The company says almost all were generated by a single AI agent from a single prompt. "This would be a striking difference from OpenAI's earlier blockbuster solution to the Navier-Stokes problem, which was produced through the collective efforts of a 10,000-strong agentic swarm that cost millions of dollars in computing power," reports Scientific American. From the report: OpenAI revealed the results in a GitHub repository at 6 P.M. EDT. The deluge will take mathematicians months to parse through and understand -- including to determine whether the proofs contain novel and important ideas or are mostly mash-ups of existing techniques. But many of the results have already been verified in Lean -- a programming language that validates a proof's logic -- and are therefore all but certain to be correct. Among the results claimed are a solution to the four-dimensional Kakeya conjecture, improvements on some of the world's most important computer algorithms and actual progress toward math's scariest problem, the Riemann hypothesis.
