Google AI Overviews put people at risk of harm with misleading health advice

People are being put at risk of harm by false and misleading health information in Google’s artificial intelligence summaries, a Guardian investigation has found.The company has said its AI Overviews, which use generative AI to provide snapshots of essential information about a topic or question, are “helpful” and “reliable”.But some of the summaries, which appear at the top of search results, served up inaccurate health information and put people at risk of harm.In one case that experts described as “really dangerous”, Google wrongly advised people with pancreatic cancer to avoid high-fat foods. Experts said this was the exact opposite of what should be recommended, and may increase the risk of patients dying from the disease

Uber rewrites contracts with drivers to avoid paying UK’s new ‘taxi tax’

Uber has swerved paying millions of pounds to the UK exchequer under Rachel Reeves’s new “taxi tax” after the ride-hailing app rewrote contracts with its drivers.The move came as rules announced in November’s budget took effect, which adjusted how VAT is payable on minicab fares and would have resulted in the whole Uber fare becoming subject to the 20% sales tax.In November, Reeves told the Commons the changes would end up “protecting around £700m of tax revenue each year”.However, updated terms issued to Uber drivers from January 2026 mean the technology firm will act as an agent, rather than as the supplier, of transport services outside London. The move means drivers make a contract directly with their passengers – so they must charge any VAT due on the fare, while Uber only adds VAT to its commission

Apple reportedly cuts production of Vision Pro headset after poor sales

Poor sales have reportedly forced Apple to cut production of the Vision Pro headset that it had hoped would herald a new era in “spatial computing”.The tech company also reduced marketing for Vision Pro by more than 95% last year, according to the market intelligence group Sensor Tower in figures first reported by the Financial Times.Apple continues to sell iPhones, iPads and laptops in the millions each quarter, but analysts say sales of Vision Pro headsets, which cost at least £3,199 ($3,499) each, have been sluggish.Apple has not released sales figures for the device, but the market research group International Data Corporation (IDC) estimates it will have sold only 45,000 in the last quarter of last year.IDC said Apple’s Chinese producer, Luxshare, had stopped production of the headset at the start of 2025, and Apple has not expanded direct sales beyond a select 13 countries

‘They sowed chaos to no avail’: the lasting legacy of Elon Musk’s Doge

The billionaire – who had no government experience – left various federal agencies in disarray while overseeing an ‘efficiency’ drive across WashingtonAs Elon Musk, the world’s richest person, splurged more than $250m on Donald Trump’s 2024 re-election campaign, the US president commissioned his new ally to oversee a sweeping “efficiency” drive across the federal government.The Tesla and SpaceX boss, who had no experience inside government, was tasked with eradicating waste and cutting spending as part of the so-called “department of government efficiency” (Doge) – and was quick to stoke expectations.“I think we can do at least $2tn,” Musk declared of the potential savings during a campaign rally at Madison Square Garden in New York a week before Trump’s re-election.Following Trump’s return to office in January, these ambitious plans were swiftly on a collision course with reality. Tens of thousands of federal workers were fired, leaving agencies in disarray and triggering myriad legal challenges

Tesla publishes analyst forecasts suggesting sales set to fall

Tesla has taken the unusual step of publishing sales forecasts that suggest 2025 deliveries will be lower than expected and future years’ sales will be well below targets set by its chief executive, Elon Musk.The US electric vehicle maker published figures from analysts suggesting it will announce 423,000 deliveries during the fourth quarter of 2025, in a new “consensus” section on its investor website. That would represent a 16% decline from the final quarter of 2024.The estimates suggested that Tesla would deliver 1.64m cars in 2025 as a whole, down from 1
