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.

Flock plans to let go of about 18% of its employees, people with direct knowledge of the plans said on Thursday, as the maker of AI-powered surveillance cameras and license-plate readers faces mounting opposition to its products from communities and lawmakers....

The company has about 1,500 employees [with job cuts hitting 270 employees]. Flock faces growing scrutiny from regulators, lawmakers, and privacy advocates, despite drawing strong investor interest among venture capitalists. A recent Reuters/Ipsos poll showed Americans are divided on whether Flock cameras are a good idea. Some 38% of the country supports the use of Flock cameras in their community, compared to 47% who oppose their use.

Cloudflare doesn’t block pirate sports streaming sites through its 1.1.1.1 DNS resolver in France, only through its CDN. The Paris Judicial Court has now accepted that stance, rejecting [French pay-TV provider] Canal+‘s request for penalties of 50,000 euros per site, per day. Interestingly, the court’s conclusion relies on statistics provided by Canal+ itself. […] As a result, Cloudflare will not be penalized under these orders, even though its public DNS resolver is not blocking the sites in question. That is in line with the company’s long-standing claim that it doesn’t interfere with its DNS.

In its recent transparency reports, Cloudflare repeatedly stated that it hasn’t blocked any content through 1.1.1.1, despite orders from French and Italian courts. “To date, Cloudflare has not blocked content through the 1.1.1.1 Public DNS Resolver,” the company’s latest report reads. […] Blocking through the CDN is another matter. According to the same report, Cloudflare geoblocked 1,238 domains in France in the second half of 2025, all under a single court order. In the first half of the year, it geoblocked 662 domains under seven orders. Cloudflare recently explained its position to the European Commission, in a submission (PDF) to its Counterfeit and Piracy Watch List consultation, stressing that global public DNS resolvers should not be used to block or restrict access.

Instead, it highlights its real-time pirate stream blocking program, which allows vetted rightsholders to flag pirate streams that run through its network. These streams are disrupted “within seconds,” Cloudflare says, without any DNS or IP address blocking. “For live content, where speed is crucial, Cloudflare has built real-time mitigation mechanisms that allow vetted rightsholder partners to flag infringing streams. When those streams are running through our network, we act on them in seconds,” Cloudflare informed the Commission. For now, Cloudflare can continue to block pirate sites through its CDN only, while its 1.1.1.1 DNS resolver remains untouched. Canal+ can still appeal the rulings, so it may not be the last we hear of it.

A physicist has put a definite date on Doomsday,” The New York Times wrote on November 4, 1960. “He calculates that it will come on Friday the Thirteenth in November, 2026 A. D. On that date, or thereabouts, the human population will have expanded so far as to approach infinity and thus will automatically annihilate itself.” The newspaper was right — but the prediction was wrong. That week, Austrian American physicist Heinz von Foerster and two colleagues published a paper in Science with the stunningly succinct title "Doomsday: Friday, 13 November, A.D. 2026.”

The work was based on a simple observation: The time it took for the human population to double in size kept getting shorter. Using population estimates from about 400 B.C.E. until 1958 C.E., the authors — all from the department of electrical engineering at the University of Illinois Urbana-Champaign — came up with an equation that best described the trend. If things continued the way they were going, the number of humans on Earth would rise faster and faster, reaching more than 25 billion by 2020. The researchers didn’t calculate when humanity would run out of food, land, or energy. They just concluded that at some point this year, the equation ceased to give meaningful results because the predicted population shot toward infinity. That was their doomsday. “Our great-great-grandchildren will not starve,” they wrote. “They will be squeezed to death.”

The exact date was somewhat arbitrary, however. The formula solved to 2026.87 plus or minus 5.5 years, and The New York Times reported that von Foerster “searched the center of this doom-time span for an appropriate date and found that a Friday the Thirteenth would fall conveniently in November of 2026.” (November 13 also happened to be his birthday.) […] [D]emographers, annoyed by what they saw as a provocation by outsiders, pointed out obvious flaws. For example, the time it takes for the number of humans to double could get a lot shorter, but certainly not shorter than the 9 months it takes for a baby to develop. “In view of the comments that subsequently were published in this journal, an extensive discussion of this article does not seem to be required,” public health expert Harold Dorn drily noted in Science 2 years after von Foerster’s article was published. The forecast would set a record, he predicted, “for the short length of time required to demonstrate its unreliability.”

A computing pioneer who authored over 130 publications, Hamilton helped to establish software engineering as a dedicated discipline. She worked at MIT from 1959 until the mid-1970s, after which she became a successful computing entrepreneur and CEO. Her life’s work was recognized with many awards and honors, including the 2016 Presidential Medal of Freedom from President Barack Obama, whose citation noted: “Hamilton defined new forms of software engineering and helped launch an industry that would forever change human history. Her software architecture led to giant leaps for humankind, writing the code that helped America set foot on the moon.”

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.

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.

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.

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.

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.

In February 2001, Slashdot readers asked Carl Kadie about censorship and privacy at colleges, and he answered. Now Kadie, who founded the Computers and Academic Freedom project at EFF in 1991, has written its history. In Part 1, Ohio State kicks a student off its network, then out of school, after a prank routes his “fuck you” into rec.aquaria, and a supercomputing center fires a student over an email from saddam@iraq.bunker.gov. In Part 2, Nebraska bans the project’s own newsletter, the FBI asks a conference attendee to show them his leg, and Playboy calls. The original archive is on GitHub.

Alphabet’s Google and gaming tools developer Unity Software announced a new platform that will allow people to create video games from simple text prompts, marking the latest incursion of generative artificial intelligence into artistic and creative industries. The initiative, called Playground, will “put game creation in the hands of millions of new creators, and bring new experiences to billions of players worldwide,” the companies said in a statement on Oct 7.

With its debut, Playground will let people 18 and older generate and customize games using natural language prompts, “no coding required.” Later in 2026, a new expanded creation experience called Unity Spark, will be integrated with Playground, providing “robust, professional-level” mechanics and high-fidelity 3D capabilities. Creators will be able to build “immersive, superlative experiences” with a simple text prompt, according to the release. Playground builds on Google’s push into world models, a type of AI that generates virtual environments in real time from text prompts, rather than just video.

To keep the device’s temperature under control, Microsoft has also developed a new cooling system that offers up to 2.5 times the thermal capacity of the 15-inch Surface Laptop 7th Edition. The Surface Laptop Ultra comes with a 15-inch PixelSense Ultra mini-LED touchscreen with a 3:2 aspect ratio, a pixel density of 262 PPI, and peak HDR brightness of up to 2,000 nits.

Despite its beefy specs, the Surface Laptop Ultra measures less than 18mm thick and weighs under 4.5 pounds (around 2kg). The laptop will be available in Platinum and Nightfall finishes. Microsoft has also increased the size of the precision haptic touchpad by more than 30% compared to the Surface Laptop 7th Edition for improved haptic input. The Surface Laptop Ultra includes a broader selection of ports, featuring USB-C, USB-A, HDMI, a 3.5mm headphone jack, and a full-size SD card reader. It also features the world’s first built-in USB-C magnetic charging.

News of the streaming rights comes around a month after Microsoft announced some major changes to Xbox Cloud Gaming. From November, the same month Grand Theft Auto VI releases, Microsoft is limiting streaming hours to just 15 hours for Xbox Game Pass Ultimate subscribers, 10 hours for Premium subscribers, and just five hours for Game Pass Essential. Microsoft is also opening up access to Xbox Cloud Gaming with a pay-as-you-go option next month, rather than being limited to Game Pass subscriptions. The pay-as-you-go option is perfectly timed for Grand Theft Auto VI, allowing those who don’t own an Xbox, or who primarily play from a phone, to stream the game by paying for a bundle of hours.

Embedded in a cubic kilometer of Antarctic ice, IceCube uses thousands of light sensors to survey the universe for neutrinos, nearly massless particles that rarely interact with other matter. Neutrinos provide information about the workings of black holes, galaxies and other objects in the cosmos. “IceCube is like no other telescope in the world,” says UW-Madison interim Chancellor Eric M. Wilcots. “And there is no other scientist quite like Francis Halzen, whose idea to create a neutrino detector under almost a mile of ice has led to a remarkable multinational and multi-institutional scientific collaboration and a fundamental shift in how we think about the universe.”

Unlike the neutral neutrino, cosmic rays are charged particles whose paths cannot be traced directly back to their sources. But the powerful cosmic accelerators that produce them, like supermassive black holes, will also produce neutrinos. These so-called “ghost particles” travel nearly undisturbed from their accelerators, giving scientists an almost direct pointer to their source. Along with observations by other telescopes, the neutrino first detected by IceCube provided the first-ever evidence of a source of high-energy cosmic rays, whose origins have been notoriously difficult to pinpoint since their discovery over 100 years ago by 1936 physics Nobel laureate Victor Hess.
