  • OpenAI Says It Has Cracked One of Math's 'Millennium Problems'
    by BeauHD on 09/09/2026 at 7:00 am

    An anonymous reader quotes a report from The New York Times: OpenAIsaid on Tuesday that its newest artificial intelligence technology had solved one of the "Millennium Problems," a collection of important unanswered math questions meant to push the world's leading mathematicians to new heights. The announcement is an another clear sign that A.I. is fundamentally changing the upper reaches of mathematics, which have long been viewed as a pinnacle of human achievement. The change has excited some mathematicians, while stirring concern among others. Over the past year, A.I. systems successfully solved a wide range of problems that have bedeviled mathematicians for decades. But these problems were not as complex, nor as closely watched, as the one that OpenAI's technology has solved over the past several days. The Millennium Problems are among the most heavily researched in the field. "This is a spectacular culmination of the arc we have seen over the past twelve months," OpenAI researcher Sebastien Bubeck said of the company's new solution. The company announced that one of its latest models, which has not yet been released to the public, needed just 88 hours to solve what mathematicians call "the Navier-Stokes existence and smoothness problem." This problem involves a series of equations that are often used to predict the weather. The equations describe the movement of water and other fluids. The Navier-Stokes problem, which has no clear practical value, asks whether these equations completely break down in certain situations. OpenAI's proof claims to have defined just such a situation. This would imply, at least theoretically, that the laws of physics themselves would break down under certain conditions: that, for example, water could be made to spontaneously explode. But mathematicians and physicists do not believe that this mathematical breakdown could really lead to such an outcome in the physical world. The Navier-Stokes problem was one of seven "Millennium Problems" selected by the Clay Mathematics Institute in the year 2000 as a way of tracking the progress of mathematics in the new millennium. The institute, founded by an American businessman named Landon T. Clay, offered a million dollars for the first correct solution to each problem. Before OpenAI's announcement, only one of the problems had been solved. OpenAI says it managed to solve the Navier-Stokes problem by coordinating as many as 10,000 AI agents, an extremely expensive process that may have cost millions of dollars in computing power. For those curious about the findings, the company has released a paper (PDF) and formal Lean proof. Read more of this story at Slashdot.

  • Star Trek Turns 60
    by BeauHD on 09/09/2026 at 3:30 am

    "Star Trek" marks its 60th anniversary today, September 8, six decades after the original series premiered in 1966 and went on to become one of the most successful science-fiction franchises in television history. Outlets across the web are commemorating the milestone with full health reports, hot takes, behind-the-scenes retrospectives, and reflections on the franchise's influence and what may lie ahead. The New York Times reports: As of 2026, the 60-year-old science fiction franchise boasts a fandom of carbon units -- sorry, humans -- that spans at least three generations. What began, in 1966, as a five-year space mission on the U.S.S. Enterprise to "boldly go where no man has gone before" now represents an anthology of space travel across more than 25 series and films in parts of two centuries. Where once it was James T. Kirk or bust, it's not unusual to find fans who prefer other captains, like Picard, Janeway or Sisko. There are so many series to keep track of that fans often communicate using country code-like abbreviations for each installment: TOS (the original series), TNG ("The Next Generation"), DS9 ("Deep Space Nine"), ENT ("Enterprise") and so on. Outside the Trekiverse, disparities in generational slang, politics and social mores are practically a foregone conclusion. But "Star Trek" functions as connective tissue between fans past and present. Some of that tissue is just shared references: There will always be captain's logs, timelines by stardate, warp factors one through 10, phasers and photon torpedoes and, every now and then, a doctor who insists, "I'm a doctor, not a ____!" The Vulcan salute has become a general symbol of geek-recognize-geek, but real Trekkies (or Trekkers, as some prefer) know that "Live long and prosper" is only half the message; the recipient is meant to say "Peace and long life" in response. But the series' staying power, and the ease with which each generation finds its way into them, is an indication that fans of all ages share not only language, but values, in common. Here are some of our favorite Slashdot stories from the early days. The 2004 "Should Star Trek Die?" is an especially good callback today because it features LeVar Burton (Geordi La Forge in Star Trek: The Next Generation) arguing that Trek needs to disappear for several years to become special again...

  • Google Will 'Degrade' Search In Europe to Avoid EU Fines
    by BeauHD on 08/09/2026 at 11:00 pm

    Google says it will overhaul Search in Europe to comply with the EU's Digital Markets Act, giving more prominence to comparison services like Expedia and Hotels.com while stripping some real-time features from hotel, airline, and restaurant results. "These changes degrade the user experience for Europeans -- boosting online intermediaries at the expense of local businesses, and removing helpful features people rely on every day," said Nick Fox, senior vice-president of knowledge and information at Google. The company claims its past search changes for DMA compliance were tied to a 30% decrease "in free, direct booking traffic to European businesses." Engadget reports: That sanction was the latest salvo between the EU government and a US tech company for infringing on its Digital Markets Act. The debate centers on the DMA requirement that major tech brands "must not treat their own services more favorably in ranking than third-party services." [...] According to Reuters, Google's revised search results "will highlight one specialized search engine at the top of the page, followed by two others with fewer details. A carousel of hotels, airlines and restaurants, for example, will sit below them with key features such as real-time prices stripped out." Those specialized engines include sites like Expedia or Hotels.com, also known as vertical search services, so European users may soon see those aggregators and comparison sites prioritized more highly than individual businesses' websites in their results. Reuters noted that "the rankings will be determined by Google's algorithm," meaning the tech company still holds a lot of control over how results are displayed. The EC had given Google 60 days to comply with its rules, but the company has not specified an exact timeline for when European users will start seeing the changes.

  • Feds Accuse China of 'Systematic' Distillation of US AI Models
    by BeauHD on 08/09/2026 at 10:02 pm

    The NSA, CISA, and FBI are accusing (PDF) several Chinese AI companies of carrying out "industrial-scale" distillation campaigns against leading U.S. models such as ChatGPT, Claude, Gemini, and Grok. Since at least 2024, the companies have allegedly routed millions of requests across accounts, APIs, proxies, cloud providers, and third-party aggregators to extract capabilities for their own models. "China-based artificial intelligence companies are conducting systematic extraction of proprietary functionalities and capabilities of U.S. AI companies' models through industrial-scale knowledge distillation campaigns that form the core -- not merely a supplement -- of their AI development strategy," the agencies wrote. CyberScoop reports: DeepSeek, for example, distilled frontier U.S. models to generate synthetic training data for its R1 and R3 models, including four different versions of Claude, two versions of Gemini, five versions of ChatGPT and Grok 4. Those models helped train DeepSeek's capabilities in areas like agentic functioning, question and answer optimization, creative and occupational writing and others. Another Chinese company, Moonshot AI, allegedly distilled 18 different U.S. models -- including Fable 5, Anthropic's current, most advanced commercially available model -- to train its Kimi-K2 and Kimi K3 models. The company used millions of queries meant to extract enhanced capabilities in areas like agentic reasoning, coding and data analysis, computer vision, larger logical frameworks, visual processing and others. Chinese AI companies manage a sophisticated set of tools and systems that route requests and prompts through multiple pathways to avoid detection. The advisory lists common tactics observed by Chinese companies, including spreading requests across different accounts, models and platforms, using native APIs, remote cloud providers, and third-party aggregators to obfuscate user metadata, and leveraging proxies and gray tech markets to get around geographic restrictions, terms of use and safeguards built into frontier models.

  • Meta Debuts Muse, Its Long-Planned Personal AI Agent
    by BeauHD on 08/09/2026 at 9:00 pm

    Meta has launched Muse, a personal AI agent developed under chief AI officer Alexandr Wang. "The product, long in development, was touted as a key next step by CEO Mark Zuckerberg in his recent 6,500-word manifesto," reports Axios. From the report: Muse, as the agent is known, exists in a chat interface, similar to a text thread. It's designed to be more proactive and long-running than typical chatbots. Users can name their agent, create an avatar and customize how it communicates. The Muse agent runs on a dedicated virtual machine in Meta's cloud, using a built-in browser that's visible to the user. Meta is offering a free tier of Muse, as well as two subscription options, at $20 per month and $100 per month. "For the vast majority of users, they should be able to do what they need to within the free tier," Wang told Axios. "But for real power users, you know, those subscription tiers help us cover the computer costs." There is no advertising within Muse, but Wang said the company is exploring commerce opportunities that could generate additional revenue. Initially Muse will be available in the U.S. and works on iOS, Android and the web, with support coming soon for Meta's AI glasses. "The full vision in the future is we want to develop personal superintelligence that helps people accomplish their goals, pursue their passions, build things that they never would have built if they didn't have the technology," Wang told Axios. Meta offers users more privacy controls with Muse than in its previous AI products, including the option to prevent queries from being used by Meta and a planned confidential mode where the company cannot see activity inside a user's virtual workspace. There's also an entirely separate system called Sentinel that governs Muse's access to the internet and connected services. Read more of this story at Slashdot.

  • Australia To Let Social Media Users 'Opt Out' of Algorithm-Based Feeds
    by BeauHD on 08/09/2026 at 8:01 pm

    Australia is proposing the "My Feed, My Way" initiative that would force social media platforms to let users over 16 turn off algorithmic recommendations and instead see only posts from people and creators they follow. Platforms that fail to comply could face fines of up to $79 million. CNBC reports: The legislation, which is being drafted and released Tuesday for targeted consultation, would require platforms to send notifications to new and existing users so they can choose their default feed. [...] The measures, set to be introduced to the Parliament of Australia this year, will also require AI chatbots, online games and other digital services to take action to protect under-18s from addictive design features. "This is not about giving government control. It's about giving people control. It's about putting choice back into the hands of Australians online," said Prime Minister Anthony at a press conference on Tuesday. "This is sensible, pragmatic, practical reform. It gives users choice, and it will hold the big tech companies responsible for inaction." Read more of this story at Slashdot.
