The new sites will boost Stargate's planned capacity to nearly 7 gigawatts--about equal to the output of seven large nuclear reactors. An aerial view shows construction underway on a Project Stargate AI infrastructure site in Abilene, Texas on April 23, 2025. OpenAI is planning to build five new data centers in the United States as part of the Stargate initiative, the company announced on Tuesday. The sites, which are being developed in partnership with Oracle and SoftBank, bring Stargate's current planned capacity to nearly 7 gigawatts--roughly the same amount of power as seven large-scale nuclear reactors . "AI is different from the internet in a lot of ways, but one of them is just how much infrastructure it takes," OpenAI CEO Sam Altman said during a press briefing in Abilene, Texas on Tuesday.

What we know, and don't, about the link between painkillers and autism Scientific evidence is lacking to support the US government's decisions to caution against using a common painkiller in pregnancy and fast-track the approval of an experimental medication for autism On Monday, the US government announced two initiatives related to autism . It will update labelling on the common painkiller paracetamol, also called acetaminophen, warning use during pregnancy may increase the risk of autism and ADHD in children . It will also approve a drug called leucovorin for use in some children with autism spectrum disorder (ASD). Neither of these moves is based on robust scientific findings, and they are likely to have minimal effect on autism rates in the US. The announcement comes after the country's highest ranking public health official, Robert F Kennedy Jr, pledged in April to identify the causes of autism by the end of September.

We introduce FinDebate, a multi-agent framework for financial analysis, integrating collaborative debate with domain-specific Retrieval-Augmented Generation (RAG). Five specialized agents, covering earnings, market, sentiment, valuation, and risk, run in parallel to synthesize evidence into multi-dimensional insights. To mitigate overconfidence and improve reliability, we introduce a safe debate protocol that enables agents to challenge and refine initial conclusions while preserving coherent recommendations. Experimental results, based on both LLM-based and human evaluations, demonstrate the framework's efficacy in producing high-quality analysis with calibrated confidence levels and actionable investment strategies across multiple time horizons.

Nvidia's $100 billion investment is meant to help OpenAI build data centers with a capacity of at least 10 gigawatts of power -- equipped with Nvidia's advanced chips to train and deploy AI models. Nvidia will invest as much as $100 billion in OpenAI to support new data centers and other artificial intelligence infrastructure, a blockbuster deal that underscores booming demand for AI tools like ChatGPT and the computing power needed to make them run. The companies announced the agreement Monday, saying they'd signed a letter of intent for a strategic deal. The investment is meant to help OpenAI build data centers with a capacity of at least 10 gigawatts of power -- equipped with Nvidia's advanced chips to train and deploy AI models. The money will be provided in stages, with the first $10 billion coming when the deal is signed, according to people familiar with the matter. Nvidia is making the investment in cash and will receive OpenAI equity as part of the deal, said the people, who asked not to be identified because the talks were private.

UK startup Wayve begins testing self-driving tech in Nissan cars on Tokyo's streets British startup Wayve has begun testing self-driving cars with Nissan in Japan ahead of a 2027 launch to consumers, as the company said it was in talks for a $500m investment from the chip-maker Nvidia . Wayve, based in London, said it had installed its self-driving technology on Nissan's electric Ariya vehicles and tested them on Tokyo's streets, after first agreeing a deal with the Japanese carmaker in April. The British company is racing against rivals - such as Tesla, Google's Waymo, and China's Baidu - to prove that its technology can work for carmakers, after rising rapidly to become one of the country's best-funded startups and a rare UK artificial intelligence pioneer. Nissan was the first carmaker to say publicly that it was using Wayve's technology, although the founder of Wayve, Alex Kendall, said the company was working with large manufacturers in Europe, North America and Japan. Wayve on Friday said Nvidia, the world's most valuable listed company, thanks to the AI boom, had signed a letter of intent for a possible $500m investment in Wayve's next funding round.

Nvidia to invest $5bn in Intel after Trump administration's 10% stake Nvidia, the world's leading chipmaker, has announced plans to invest $5bn in Intel and collaborate with the struggling semiconductor company on products. A month after the Trump administration confirmed it had taken a 10% stake in Intel - the latest extraordinary intervention by the White House in corporate America - Nvidia said it would team up with the firm to work on custom datacenters that form the backbone of artificial intelligence (AI) infrastructure, as well as personal computer products. Intel shares jumped nearly 23% after markets closed, making it the largest one-day percentage gain for the company since 1987.

President Donald Trump and U.K. Prime Minister Sir Keir Starmer signed what the latter referred to as a "groundbreaking" new U.K.-U.S. Tech Prosperity Deal on Thursday. Praising the commitment, Starmer said "the deals and investment being announced today break all records." "What a day, 250 billion pounds [340 billion dollars] flowing both ways across the Atlantic," Starmer said. "It is the biggest investment package of its kind in British history by a country mile." The deal focuses heavily on AI investment, with Starmer announcing significant investments from companies including Nvidia, Nscale, OpenAI, Google, and Salesforce that would create "cutting-edge British jobs for years to come."

OpenAI will restrict how ChatGPT responds to a user it suspects is under 18. OpenAI will restrict how ChatGPT responds to a user it suspects is under 18. Sam Altman said if there is doubt the system will default to the under-18 experience putting'safety ahead of privacy and freedom for teens' OpenAI will restrict how ChatGPT responds to a user it suspects is under 18, unless that user passes the company's age estimation technology or provides ID, after legal action from the family of a 16-year-old who killed himself in April after months of conversations with the chatbot. OpenAI was prioritising "safety ahead of privacy and freedom for teens", chief executive Sam Altman said in a blog post on Tuesday, stating "minors need significant protection". The company said that the way ChatGPT responds to a 15-year-old should look different to the way it responds to an adult.

NATO to beef up defense of Europe's eastern flank after Poland drone incursions NATO Supreme Allied Commander Europe Gen. Alexus G. Grynkewich speaks during a news conference on the violation of Polish airspace by Russian drones, at the NATO headquarters in Brussels on Friday. BRUSSELS/WARSAW/UNITED NATIONS - NATO announced plans to beef up the defense of Europe's eastern flank on Friday, two days after Poland shot down drones that had violated its airspace in the first known action of its kind by a member of the Western alliance during Russia's war in Ukraine. At the United Nations, the United States called the airspace violations alarming and vowed to defend every inch of NATO territory, remarks that appeared aimed at assuaging Washington's NATO allies after President Donald Trump said Russia's drone incursion could have been a mistake. Warsaw has portrayed the drone incursions as an attempt by Russia to test the capabilities of Poland and NATO to respond. In a time of both misinformation and too much information, quality journalism is more crucial than ever.
