Till Jeff us do part: divisive, star-studded Bezos wedding hits full swing in Venice

The Black Death. Byron on the prowl. Rising water levels. Cruise ships the size of city blocks. Venice may have endured many tumultuous events and sinister challenges over the centuries but rarely in its long history has it had to contend with an issue quite as odd and quite as divisive as the sort-of nuptials of the world’s fourth-richest person

Google’s emissions up 51% as AI electricity demand derails efforts to go green

Google’s carbon emissions have soared by 51% since 2019 as artificial intelligence hampers the tech company’s efforts to go green.While the corporation has invested in renewable energy and carbon removal technology, it has failed to curb its scope 3 emissions, which are those further down the supply chain, and are in large part influenced by a growth in datacentre capacity required to power artificial intelligence.The company reported a 27% increase in year-on-year electricity consumption as it struggles to decarbonise as quickly as its energy needs increase.Datacentres play a crucial role in training and operating the models that underpin AI models such as Google’s Gemini and OpenAI’s GPT-4, which powers the ChatGPT chatbot. The International Energy Agency estimates that datacentres’ total electricity consumption could double from 2022 levels to 1,000TWh (terawatt hours) in 2026, approximately Japan’s level of electricity demand

Trump’s tax bill seeks to prevent AI regulations. Experts fear a heavy toll on the planet

US Republicans are pushing to pass a major spending bill that includes provisions to prevent states from enacting regulations on artificial intelligence. Such untamed growth in AI will take a heavy toll upon the world’s dangerously overheating climate, experts have warned.About 1bn tons of planet-heating carbon dioxide are set to be emitted in the US just from AI over the next decade if no restraints are placed on the industry’s enormous electricity consumption, according to estimates by researchers at Harvard University and provided to the Guardian.This 10-year timeframe, a period of time in which Republicans want a “pause” of state-level regulations upon AI, will see so much electricity use in data centers for AI purposes that the US will add more greenhouse gases to the atmosphere than Japan does annually, or three times the yearly total from the UK.The exact amount of emissions will depend on power plant efficiency and how much clean energy will be used in the coming years, but the blocking of regulations will also be a factor, said Gianluca Guidi, visiting scholar at the Harvard TH Chan School of Public Health

Gov.uk smartphone app to launch with limited functionality

A government app intended to “cut life admin” will be free to download by millions of UK citizens from Tuesday, but its functions will be limited and the cabinet minister in charge has admitted: “The design is not as we would like it to be.”The gov.uk app will be accessible on smartphones for people aged 16 and over and is intended to be the main mobile hub for many citizen interactions with the government, although not the NHS or HM Revenue and Customs.Peter Kyle, the secretary of state for science and technology, said the version launched this week would only steer users to existing government webpages, with more functionality to be added by the end of the year.A generative artificial intelligence chatbot trained on 700,000 pages of the gov

Microsoft says AI system better than doctors at diagnosing complex health conditions

Microsoft has revealed details of an artificial intelligence system that performs better than human doctors at complex health diagnoses, creating a “path to medical superintelligence”.The company’s AI unit, which is led by the British tech pioneer Mustafa Suleyman, has developed a system that imitates a panel of expert physicians tackling “diagnostically complex and intellectually demanding” cases.Microsoft said that when paired with OpenAI’s advanced o3 AI model, its approach “solved” more than eight of 10 case studies specially chosen for the diagnostic challenge. When those case studies were tried on practising physicians – who had no access to colleagues, textbooks or chatbots – the accuracy rate was two out of 10.Microsoft said it was also a cheaper option than using human doctors because it was more efficient at ordering tests

Jeff Bezos and Lauren Sánchez arrive in Venice for divisive wedding

The billionaire Amazon founder, Jeff Bezos, and the former TV journalist Lauren Sánchez have arrived in Venice as they prepare to tie the knot in a lavish three-day celebration that has divided the lagoon city.Scores of celebrities and other members of the world’s super-rich will also join the pair in Italy, arriving on superyachts and private jets.Bezos, the world’s fourth-richest person, and Sánchez were seen stepping off a water taxi on Wednesday as they entered the exclusive Aman Venice hotel on the Grand Canal, where many of the celebrities will stay.More than 90 private jets are expected to land in Venice before the celebrations officially begin on Thursday, bringing in guests for an event that some have called the “wedding of the century” and is rumoured to involve everything from pyjama parties to elegant dinners.Among the first guests to arrive were Donald Trump’s daughter Ivanka, her husband, Jared Kushner, and their children
