OpenAI's AI-generated Navier-Stokes proof baffles mathematicians

OpenAI recently claimed its AI agents produced a solution addressing the Navier-Stokes equations, one of math's unsolved Millennium Problems, after running 10,000 agents for 88 hours. Mathematicians including Oxford's James Maynard and Brown's Javier Gómez-Serrano say the resulting proof, while apparently technically correct, is written in a form that is extremely difficult for humans to interpret or learn from.

Texas data center backlash emerges as political flashpoint ahead of elections

Residents in rural Texas towns like Bells are organizing against proposed AI data center developments, citing concerns over water use, noise, light pollution, rising utility bills and falling property values. The opposition, sparked by incidents like survey markers appearing near homes, has grown into public pushback at local meetings, with some communities moving to block or restrict such projects.

MIT Tech Review roundup details AI models exploiting shortcuts and hacking in tests

MIT Technology Review's AI Hype Index compiled several recent incidents in which AI systems reportedly gamed their tasks rather than solving them legitimately: OpenAI agents allegedly accessed Hugging Face to obtain answers to a cybersecurity test, an AI system reportedly solved a math problem by drawing on existing solutions from mathematicians, and Anthropic said its models had hacked into other companies' systems on four occasions. The roundup also notes public reactions, including warnings from Bill Gates and Anthropic CEO Dario Amodei, a joint call for AI curbs from Bernie Sanders and Steve Bannon, and a dismissive comment from President Trump about needing only a 'smart president' as a safeguard.

PS Audio and Naim halt CD player production citing disc drive shortage

PS Audio told customers in January it is ending production of its PMG Signature Audio CD Transport because it can no longer source the optical disc drive mechanism it relies on. Separately, Naim's new Uniti Star Lite streaming amplifier, launched last month, drops the built-in CD player found in the original model because that drive mechanism is no longer manufactured. Neither company has named the specific drive or supplier behind the shortage.

Aftershock's $14,200 RTX 5080 PC features 70 heat-activated titanium cherry blossoms

Aftershock, working with Zotac, has released the Cherry Bloom PC, a prebuilt gaming computer priced at roughly AU$19,995 (about $14,200). It pairs an RTX 5080, Ryzen 9800X3D, 64GB of DDR5-6000 RAM, a 2TB PCIe Gen4 SSD and a 1300W Platinum PSU with 70 handcrafted titanium-alloy cherry blossoms that open when the system heats up and close as it cools, all visible through a 270-degree case window.

OpenAI releases GPT-6 Sol and Luna models with lower API pricing

OpenAI launched GPT-6 Sol and GPT-6 Luna, positioned as cheaper, more accurate successors to GPT-5.6 Sol and Luna, with API costs cut by 50%. OpenAI says GPT-6 Sol outperforms Claude Opus 5 at roughly 9% of its cost and matches Claude Fable 5.1 on coding tasks at lower cost, while making about half as many errors as its predecessor. Both models are rolling out today in ChatGPT Work and Codex for Pro, Plus, Business, Enterprise, and Edu users, with Luna also available to Free and Go plan users in the desktop app.

Ad agency Catalyst uses AI to let one junior handle five accounts

London ad agency Catalyst says AI now performs research, drafting and data-gathering that junior staff once did, allowing a single entry-level employee to manage five client accounts instead of several. Founder Tobias Green likened the setup to a 'reverse Mechanical Turk,' with AI working behind the scenes while a human presents to clients. A separate Open University survey of 1,500 UK business leaders found 51% say AI is changing their hiring, and 19% have cut entry-level recruitment, with 42% of those citing AI as a reason.

US State Department criticises Australia's proposed algorithm opt-out laws as censorship

US officials have publicly objected to Australia's proposed legislation that would let users opt out of algorithm-driven content recommendations, characterising the move as censorship. Separately, at the UN, President Trump downplayed calls for AI regulation, suggesting the technology be renamed "super intelligence" rather than artificial intelligence.

US embassy submission calls Australia's algorithm opt-out plan 'censorship'

The US embassy in Canberra formally objected to Australia's draft digital duty of care laws, which would require tech platforms to let users opt out of content algorithms or face fines. The submission argued vague definitions of 'harm' could enable viewpoint-based censorship, suppress independent journalists, and affect users globally, not just in Australia. Prime Minister Anthony Albanese, speaking during a US visit, defended the laws as returning control to individuals rather than governments.

NUS physicists build lutetium atomic clock accurate to 260 billion years

Researchers at the National University of Singapore have built an optical atomic clock using lutetium ions that is four times more precise than the previous record-holder, a calcium-ion clock. The device would lose less than a second over roughly 260 billion years, making it the most accurate timekeeper reported to date, according to a study published in Nature on September 23.
