Mathematicians have identified the first shape that cannot pass through itself. Jakob Steininger and Sergey Yurkevich described the Noperthedron in a paper posted online in August. The shape has 90 vertices and 152 faces. The discovery resolves a question that began in the late 1600s when Prince Rupert of the Rhine won a bet by proving one cube could slide through a tunnel bored through another. Mathematician John Wallis confirmed this mathematically in 1693. The property became known as the Rupert property. In 1968, Christoph Scriba proved the tetrahedron and octahedron also possess this quality. Over the past decade, researchers found Rupert tunnels through many symmetric polyhedra, including the dodecahedron and icosahedron. Mathematicians had conjectured every convex polyhedron would have the Rupert property. Steininger and Yurkevich divided the space of possible orientations into approximately 18 million blocks and tested each. None produced a passage. The Noperthedron consists of 150 triangles and two regular 15-sided polygons.

Finland's fertility rate has dropped below 1.3 children per woman, the lowest among Nordic countries and far beneath the 2.1 replacement level needed to maintain a steady population. The rate has declined by a third since 2010. Kela, Finland's social insurance agency, started distributing 2025 "baby boxes" -- filled with clothing and other infant supplies -- in August instead of spring because so many 2024 boxes remained unclaimed. More parents now choose cash payments over the traditional boxes filled with infant supplies. The decline puzzles researchers because Finland offers paid parental leave for both mothers and fathers, subsidized childcare and national healthcare. Anneli Miettinen, Kela's research manager, said that good family policies no longer explain birth rates in Nordic countries. Immigration has offset some population loss, but officials worry about workforce shrinkage and pension system strain. Anna Rotkirch, who authored a government-commissioned report, found that many 17-year-olds describe wanting a house, garden, spouse and three children. Her research suggests young people struggle to form relationships, focus on education and careers, and delay childbearing. Some researchers attribute relationship difficulties to technology reducing physical interactions.

Australia's competition regulator sued Microsoft today, accusing it of misleading millions of customers into paying higher prices for its Microsoft 365 software after bundling it with AI tool Copilot. From a report: The Australian Competition and Consumer Commission alleged that from October 2024, the technology giant misled about 2.7 million customers by suggesting they had to move to higher-priced Microsoft 365 personal and family plans that included Copilot. After the integration of Copilot, the annual subscription price of the Microsoft 365 personal plan increased by 45% to A$159 ($103.32) and the price of the family plan increased by 29% to A$179, the ACCC said. The regulator said Microsoft failed to clearly tell users that a cheaper "classic" plan without Copilot was still available.

The U.S. has formed a $1 billion partnership with AMD to construct two supercomputers that will tackle large scientific problems ranging from nuclear power to cancer treatments to national security, said Energy Secretary Chris Wright and AMD CEO Lisa Su. From a report: The U.S. is building the two machines to ensure the country has enough supercomputers to run increasingly complex experiments that require harnessing enormous amounts of data-crunching capability. The machines can accelerate the process of making scientific discoveries in areas the U.S. is focused on. Energy Secretary Wright said the systems would "supercharge" advances in nuclear power and fusion energy, technologies for defense and national security, and the development of drugs. Scientists and companies are trying to replicate fusion, the reaction that fuels the sun, by jamming light atoms in a plasma gas under intense heat and pressure to release massive amounts of energy. "We've made great progress, but plasmas are unstable, and we need to recreate the center of the sun on Earth," Wright told Reuters.

Countries signed their first UN treaty targeting cybercrime in Hanoi on Saturday, despite opposition from an unlikely band of tech companies and rights groups warning of expanded state surveillance. From a report: The new global legal framework aims to strengthen international cooperation to fight digital crimes, from child pornography to transnational cyberscams and money laundering. More than 60 countries were seen to sign the declaration Saturday, which means it will go into force once ratified by those states. UN Secretary General Antonio Guterres described the signing as an "important milestone", but that it was "only the beginning". "Every day, sophisticated scams, destroy families, steal migrants and drain billions of dollars from our economy... We need a strong, connected global response," he said at the opening ceremony in Vietnam's capital on Saturday. The UN Convention against Cybercrime was first proposed by Russian diplomats in 2017, and approved by consensus last year after lengthy negotiations. Critics say its broad language could lead to abuses of power and enable the cross-border repression of government critics.

Electronic Arts has spent the past year pushing its nearly 15,000 employees to use AI for everything from code generation to scripting difficult conversations about pay. Employees in some areas must complete multiple AI training courses and use tools like the company's in-house chatbot ReefGPT daily. The tools produce flawed code and hallucinations that employees then spend time correcting. Staff say the AI creates more work rather than less, according to Business Insider. They fix mistakes while simultaneously training the programs on their own work. Creative employees fear the technology will eventually eliminate demand for character artists and level designers. One recently laid-off senior quality-assurance designer says AI performed a key part of his job -- reviewing and summarizing feedback from hundreds of play testers. He suspects this contributed to his termination when about 100 colleagues were let go this past spring from the company's Respawn Entertainment studio.

OpenAI's rival Anthropic has a different approach — and "a clearer path to making a sustainable business out of AI," writes the Wall Street Journal. Outside of OpenAI's close partnership with Microsoft, which integrates OpenAI's models into Microsoft's software products, OpenAI mostly caters to the mass market... which has helped OpenAI reach an annual revenue run rate of around $13 billion, around 30% of which it says comes from businesses. Anthropic has generated much less mass-market appeal. The company has said about 80% of its revenue comes from corporate customers. Last month it said it had some 300,000 of them... Its cutting-edge Claude language models have been praised for their aptitude in coding: A July report from Menlo Ventures — which has invested in Anthropic — estimated via a survey that Anthropic had a 42% market share for coding, compared with OpenAI's 21%. Anthropic is also now ahead of OpenAI in market share for overarching corporate AI use, Menlo Ventures estimated, at 32% to OpenAI's 25%. Anthropic is also surprisingly close to OpenAI when it comes to revenue. The company is already at a $7 billion annual run rate and expects to get to $9 billion by the end of the year — a big lead over its better-known rival in revenue per user. Both companies have backing in the form of investments from big tech companies — Microsoft for OpenAI, and a combination of Amazon and Google for Anthropic — that help provide AI computing infrastructure and expose their products to a broad set of customers. But Anthropic's growth path is a lot easier to understand than OpenAI's. Corporate customers are devising a plethora of money-saving uses for AI in areas like coding, drafting legal documents and expediting billing. Those uses are likely to expand in the future and draw more customers to Anthropic, especially as the return on investment for them becomes easier to measure... Demonstrating how much demand there is for Anthropic among corporate customers, Microsoft in September said Anthropic's leading language model, Claude, would be offered within its Copilot suite of software despite Microsoft's ties to OpenAI. "There is also a possibility that OpenAI's mass-market appeal becomes a turnoff for corporate customers," the article adds, "who want AI to be more boring and useful than fun and edgy."

"Mozilla is introducing a new privacy framework for Firefox extensions that will require developers to disclose whether their add-ons collect or transmit user data..." reports the blog Linuxiac: The policy takes effect on November 3, 2025, and applies to all new Firefox extensions submitted to addons.mozilla.org. According to Mozilla's announcement, extension developers must now include a new key in their manifest.json files. This key specifies whether an extension gathers any personal data. Even extensions that collect nothing must explicitly state "none" in this field to confirm that no data is being collected or shared. This information will be visible to users at multiple points: during the installation prompt, on the extension's listing page on addons.mozilla.org, and in the Permissions and Data section of Firefox's about:addons page. In practice, this means users will be able to see at a glance whether a new extension collects any data before they install it.

Slashdot reader joshuark writes: Microsoft says that the File Explorer (formerly Windows Explorer) now automatically blocks previews for files downloaded from the Internet to block credential theft attacks via malicious documents, according to a report from BleepingComputer. This attack vector is particularly concerning because it requires no user interaction beyond selecting a file to preview and removes the need to trick a target into actually opening or executing it on their system. For most users, no action is required since the protection is enabled automatically with the October 2025 security update, and existing workflows remain unaffected unless you regularly preview downloaded files. "This change is designed to enhance security by preventing a vulnerability that could leak NTLM hashes when users preview potentially unsafe files," Microsoft says in a support document published Wednesday. It is important to note that this may not take effect immediately and could require signing out and signing back in.

America's largest university system, with 460,000 students, is the 22-campus "Cal State" system, reports the New York Times. And it's recently teamed with Amazon, OpenAI and Nvidia, hoping to embed chatbots in both teaching and learning to become what it says will be America's "first and largest AI-empowered" university" — and prepare students for "increasingly AI-driven" careers. It's part of a trend of major universities inviting tech companies into "a much bigger role as education thought partners, AI instructors and curriculum providers," argues the New York Times, where "dominant tech companies are now helping to steer what an entire generation of students learn about AI, and how they use it — with little rigorous evidence of educational benefits and mounting concerns that chatbots are spreading misinformation and eroding critical thinking..." "Critics say Silicon Valley's effort to make AI chatbots integral to education amounts to a mass experiment on young people." As part of the effort, [Cal State] is paying OpenAI $16.9 million to provide ChatGPT Edu, the company's tool for schools, to more than half a million students and staff — which OpenAI heralded as the world's largest rollout of ChatGPT to date. Cal State also set up an AI committee, whose members include representatives from a dozen large tech companies, to help identify the skills California employers need and improve students' career opportunities... Cal State is not alone. Last month, California Community Colleges, the nation's largest community college system, announced a collaboration with Google to supply the company's "cutting edge AI tools" and training to 2.1 million students and faculty. In July, Microsoft pledged $4 billion for teaching AI skills in schools, community colleges and to adult workers... [A]s schools like Cal State work to usher in what they call an "AI-driven future," some researchers warn that universities risk ceding their independence to Silicon Valley. "Universities are not tech companies," Olivia Guest and Iris van Rooij, two computational cognitive scientists at Radboud University in the Netherlands, recently said in comments arguing against fast AI adoption in academia. "Our role is to foster critical thinking," the researchers said, "not to follow industry trends uncritically...." Some faculty members have pushed back against the AI effort, as the university system faces steep budget cuts. The multimillion-dollar deal with OpenAI — which the university did not open to bidding from rivals like Google — was wasteful, they added. Faculty senates on several Cal State campuses passed resolutions this year criticizing the AI initiative, saying the university had failed to adequately address students using chatbots to cheat. Professors also said administrators' plans glossed over the risks of AI to students' critical thinking and ignored troubling industry labor practices and environmental costs. Martha Kenney, a professor of women and gender studies at San Francisco State University, described the AI program as a Cal State marketing vehicle helping tech companies promote unproven chatbots as legitimate educational tools. The article notes that Cal State's chief information officer "defended the OpenAI deal, saying the company offered ChatGPT Edu at an unusually low price. "Still, California's community college system landed AI chatbot services from Google for more than 2 million students and faculty — nearly four times the number of users Cal State is paying OpenAI for — for free."

GM plans to dump Apple CarPlay and Android Auto on all its car new vehicles "in the near future," reports the Verge. In an episode of the Verge's Decoder podcast, GM CEO Mary Barra confirmed the upcoming change to "phone projections" for GM cars: The timing is unclear, but Barra pointed to a major rollout of what the company is calling a new centralized computing platform, set to launch in 2028, that will involve eventually transitioning its entire lineup to a unified in-car experience. In place of phone projection, GM is working to update its current Android-powered infotainment implementation with a Google Gemini-powered assistant and an assortment of other custom apps, built both in-house and with partners. GM's 2023 decision to drop CarPlay and Android Auto support in its EVs has proved controversial, though for now GM has maintained support for phone projection in its gas-powered vehicles.

North Dakota experienced an almost 40% increase in electricity demand "thanks in part to an explosion of data centers," reports the Washington Post. Yet the state saw a 1% drop in its per kilowatt-hour rates. "A new study from researchers at Lawrence Berkeley National Laboratory and the consulting group Brattle suggests that, counterintuitively, more electricity demand can actually lower prices..." Between 2019 and 2024, the researchers calculated, states with spikes in electricity demand saw lower prices overall. Instead, they found that the biggest factors behind rising rates were the cost of poles, wires and other electrical equipment — as well as the cost of safeguarding that infrastructure against future disasters... [T]he largest costs are fixed costs — that is, maintaining the massive system of poles and wires that keeps electricity flowing. That system is getting old and is under increasing pressures from wildfires, hurricanes and other extreme weather. More power customers, therefore, means more ways to divvy up those fixed costs. "What that means is you can then take some of those fixed infrastructure costs and end up spreading them around more megawatt-hours that are being sold — and that can actually reduce rates for everyone," said Ryan Hledik [principal at Brattle and a member of the research team]... [T]he new study shows that the costs of operating and installing wind, natural gas, coal and solar have been falling over the past 20 years. Since 2005, generation costs have fallen by 35 percent, from $234 billion to $153 billion. But the costs of the huge wires that transmit that power across the grid, and the poles and wires that deliver that electricity to customers, are skyrocketing. In the past two decades, transmission costs nearly tripled; distribution costs more than doubled. Part of that trend is from the rising costs of parts: The price of transformers and wires, for example, has far outpaced inflation over the past five years. At the same time, U.S. utilities haven't been on top of replacing power poles and lines in the past, and are now trying to catch up. According to another report from Brattle, utilities are already spending more than $10 billion a year replacing aging transmission lines. And finally, escalating extreme-weather events are knocking out local lines, forcing utilities to spend big to make fixes. Last year, Hurricane Beryl decimated Houston's power grid, forcing months of costly repairs. The threat of wildfires in the West, meanwhile, is making utilities spend billions on burying power lines. According to the Lawrence Berkeley study, about 40 percent of California's electricity price increase over the last five years was due to wildfire-related costs. Yet the researchers tell the Washington Post that prices could still increase if utilities have to quickly build more infrastructure just to handle data center. But their point is "This is a much more nuanced issue than just, 'We have a new data center, so rates will go up.'" As the article points out, "Generous subsidies for rooftop solar also increased rates in certain states, mostly in places such as California and Maine... If customers install rooftop solar panels, demand for electricity shrinks, spreading those fixed costs over a smaller set of consumers.

"Snippets of proprietary or copyleft reciprocal code can enter AI-generated outputs, contaminating codebases with material that developers can't realistically audit or license properly." That's the warning from Sean O'Brien, who founded the Yale Privacy Lab at Yale Law School. ZDNet reports: Open software has always counted on its code being regularly replenished. As part of the process of using it, users modify it to improve it. They add features and help to guarantee usability across generations of technology. At the same time, users improve security and patch holes that might put everyone at risk. But O'Brien says, "When generative AI systems ingest thousands of FOSS projects and regurgitate fragments without any provenance, the cycle of reciprocity collapses. The generated snippet appears originless, stripped of its license, author, and context." This means the developer downstream can't meaningfully comply with reciprocal licensing terms because the output cuts the human link between coder and code. Even if an engineer suspects that a block of AI-generated code originated under an open source license, there's no feasible way to identify the source project. The training data has been abstracted into billions of statistical weights, the legal equivalent of a black hole. The result is what O'Brien calls "license amnesia." He says, "Code floats free of its social contract and developers can't give back because they don't know where to send their contributions...." "Once AI training sets subsume the collective work of decades of open collaboration, the global commons idea, substantiated into repos and code all over the world, risks becoming a nonrenewable resource, mined and never replenished," says O'Brien. "The damage isn't limited to legal uncertainty. If FOSS projects can't rely upon the energy and labor of contributors to help them fix and improve their code, let alone patch security issues, fundamentally important components of the software the world relies upon are at risk." O'Brien says, "The commons was never just about free code. It was about freedom to build together." That freedom, and the critical infrastructure that underlies almost all of modern society, is at risk because attribution, ownership, and reciprocity are blurred when AIs siphon up everything on the Internet and launder it (the analogy of money laundering is apt), so that all that code's provenance is obscured.

Can YouTube capture the hours people spending watching "traditional" TV? YouTube's CEO recently said its viewership on TV sets has "surpassed mobile and is now the primary device for YouTube viewing in the U.S.," writes The Hollywood Reporter. And YouTube is shelling out big money to stay on top: It's come a long way since the 19-second "me at the zoo" video was uploaded in April 2005. Now, per a KPMG report released Sept. 23, YouTube is second only to Comcast in terms of annual content spend, inclusive of payments to creators and media companies, paying out as much as Netflix and Paramount combined, $32 billion... The only question is what genres it will take over next, and how quickly it will do so. From talk shows to scripted dramas to, yes, live sports, there are signs that the platform's ambitions will collide with the traditional TV business sooner rather than later... YouTube has slowly, then all at once, become the de facto home for what had been late night, not only for the shows on linear TV, but for an emerging crop of new talent born on the platform. As it happens, late night itself transformed YouTube when the Saturday Night Live skit "Lazy Sunday" went viral 20 years ago on the platform, which had only been live for a few months... As consumer preferences collide with a burgeoning ecosystem of video podcasts (YouTube now claims more than 1 billion podcast users monthly), the world of late night, and for that matter TV talk shows more generally, increasingly revolves around the platform. One current late night producer says that almost every A-list booking now includes some sort of sketch or bit that they think will play well on YouTube, but booking those guests in the first place has become less of a sure thing. A veteran Hollywood publicist says that for many of their clients, they are now recommending that YouTube podcasts or shows become the first stop, or at least a major stop, on press tours... Nielsen has been tracking the streaming platforms that consumers watch on their TV screens ever since it launched what it calls The Gauge in 2021. But over the past year, YouTube's domination of The Gauge has unnerved executives at some competitors. The most recent Gauge report showed that YouTube was by far the most watched video platform, holding 13.1 percent share. Netflix, in second place, was at 8.7 percent. The article suggests YouTube's last challenge may be "scripted" entertainment — where their business model is different than Netflix or HBO. "On YouTube, it is up to the creator to finance and produce their content, and while the platform regularly releases new tools to help them (including AI-enabled tech that suggests video ideas and can create short background videos for use in Shorts), scripted entertainment is a particularly tricky challenge, requiring writers, directors, sets, costumes, lighting, editing, special effects and other production requirements that may go beyond the typical creator-led show."

Long-time Slashdot reader schwit1 shares this article from Interesting Engineering: Bill Gates-backed TerraPower's innovative Natrium reactor project in Wyoming has cleared a critical federal regulatory hurdle. The US Nuclear Regulatory Commission (NRC) has successfully completed its final Environmental Impact Statement (EIS) for the project, known as Kemmerer Unit 1, and found no adverse impacts that would block its construction. The commission officially recommended that a construction permit be issued to TerraPower subsidiary USO for the facility in Lincoln County. This announcement marks a significant milestone, making the Natrium project the first-ever advanced commercial nuclear power plant in the country to successfully complete this rigorous environmental review process... The first-of-a-kind design utilizes an 840 MW (thermal) pool-type reactor connected to a molten salt-based energy storage system. This storage technology is the plant's most unique feature. It is designed to keep the base output steady, ensuring constant reliability, but it also allows the plant to function like a massive battery. The system can store heat and boost the plant's output to 500 MWe when demand peaks, allowing it to ramp up power quickly to support the grid. TerraPower says it is the only advanced reactor design with this unique capability. The Natrium plant is strategically designed to replace electricity generation capacity following the planned retirement of existing coal-fired facilities in the region. While the regulatory process for the nuclear components continues, construction on the non-nuclear portions of the site already began in June 2024. When completed, the Natrium plant is poised to be the first utility-scale advanced nuclear power plant in the United States. The next step for the construction permit application is a final safety evaluation, which is anticipated by December 31, 2025, according to announcement from TerraPower, which notes that the project is being developed through a public-private partnership with the U.S. Energy Department. "When completed, the Natrium plant will be the first utility-scale advanced nuclear power plant in the United States."

Has AI just become an easy excuse for firms looking to downsize, asks CNBC: Fabian Stephany, assistant professor of AI and work at the Oxford Internet Institute, said there might be more to job cuts than meets the eye. Previously there may have been some stigma attached to using AI, but now companies are "scapegoating" the technology to take the fall for challenging business moves such as layoffs. "I'm really skeptical whether the layoffs that we see currently are really due to true efficiency gains. It's rather really a projection into AI in the sense of 'We can use AI to make good excuses,'" Stephany said in an interview with CNBC. Companies can essentially position themselves at the frontier of AI technology to appear innovative and competitive, and simultaneously conceal the real reasons for layoffs, according to Stephany... Some companies that flourished during the pandemic "significantly overhired" and the recent layoffs might just be a "market clearance...." One founder, Jean-Christophe Bouglé even said in a popular LinkedIn post that AI adoption is at a "much slower pace" than is being claimed and in large corporations "there's not much happening" with AI projects even being rolled back due to cost or security concerns. "At the same time there are announcements of big layoff plans 'because of AI.' It looks like a big excuse, in a context where the economy in many countries is slowing down..." The Budget Lab, a non-partisan policy research center at Yale University, released a report on Wednesday which showed that U.S. labor has actually been little disrupted by AI automation since the release of ChatGPT in 2022... Additionally, New York Fed economists released research in early September which showed that AI use amongst firms "do not point to significant reductions in employment" across the services and manufacturing industry in the New York-Northern New Jersey region.

"Around tables cluttered with dice, maps and character sheets, players are doing far more than playing," writes Phys.org. It's what sociologists call serious leisure — "a hobby that demands skill, commitment and personal fulfillment," according to an associate professor/program director for Florida International University's Rehabilitation and Recreational Therapy Program: To understand what makes D&D more than just a pastime, [associate professor Emily Messina] studies how games like this promote identity-building and connection... Beyond personal expression, Messina says the social and emotional benefits of D&D reflect the very traits that make serious leisure valuable: the sense of identity, the relationships built through shared experiences and the continued connection with the same group of people over time... The game can also provide structure and purpose for people managing mental illness who might not be able to hold a full-time job because of their symptoms. The game gives them structure versus filling their day with binge streaming... Activities such as D&D can be used by young children as a reward structure or with older adults, such as retirees, to help provide a sense of purpose and daily rhythm. "Post retirement is one of the most dangerous points in an adult's life," she said. "They lose that sense of structure and possibly their social connection." Building structure through leisure pursuits after retirement has been shown to help maintain physical fitness, social interaction, cognitive processing and attention span and decrease depression. "The idea of structure and reward with desired pursuit can work for all ages," Messina said. The research was published in Leisure Studies.
