Elon Musk's AI model Grok will no longer be able to edit photos of real people to show them in revealing clothing, after widespread concern over sexualised AI deepfakes in countries including the UK and US. We have implemented technological measures to prevent the Grok account from allowing the editing of images of real people in revealing clothing such as bikinis. This restriction applies to all users, including paid subscribers, reads an announcement on X, which operates the Grok AI tool. The change was announced hours after California's top prosecutor said the state was probing the spread of sexualised AI deepfakes, including of children, generated by the AI model. The update expands measures that stop all users, including paid subscribers, editing images of real people in revealing outfits.

Zelensky declares state of emergency in Ukraine's energy sector Ukraine has declared a state of emergency in the country's energy sector, with particular focus on Kyiv, as ongoing Russian strikes continue to leave thousands of residents without power. The nation is in the midst of a particularly cold winter, with overnight temperatures in Kyiv dropping to around -20C. After a special cabinet meeting, President Volodymyr Zelensky said a round-the-clock task force would be set up to deal with the damaging consequences of Russian airstrikes and worsening weather conditions. He accused Moscow of deliberately exploiting the harsh, sub-zero temperatures to target critical infrastructure, including energy distribution facilities. In recent weeks, Kyiv has been particularly affected by Russian attacks, leaving thousands of homes without regular power, heating or running water.

California's top prosecutor has launched an investigation into the spread of sexualised AI deepfakes generated by Elon Musk's AI model Grok. Attorney General Rob Bonta said in a statement announcing the probe: The avalanche of reports detailing the non-consensual, sexually explicit material that xAI has produced and posted online in recent weeks is shocking. California's inquiry comes as British Prime Minister Sir Keir Starmer warns of possible action against X. In Wednesday's statement, Bonta said: This material, which depicts women and children in nude and sexually explicit situations, has been used to harass people across the internet. The Democratic prosecutor urged xAI to take immediate action.

Home Secretary Shabana Mahmood says she has lost confidence in West Midlands Police's chief constable after Israeli football fans were banned from a match against Aston Villa. Mahmood told MPs a damning review from the policing watchdog over the intelligence that led to Maccabi Tel Aviv fans being banned showed a failure of leadership. The force has apologised saying it did not deliberately distort evidence that was used by Birmingham's Safety Advisory Group for the 6 November game . Chief Constable Craig Guildford remains in post, but faces a meeting on 27 January to be questioned by Police and Crime Commissioner Simon Foster who has the authority to sack him. Mahmood told the Commons on Wednesday she intended to restore the power for home secretaries to dismiss chief constables who fail their communities.

When a police force is supposed to seek the truth and uphold the law, what happens when the evidence they present to officials and the public is, as Home Secretary Shabana Mahmood put it, exaggerated or untrue? The police inspectorate has concluded the leaders of West Midlands Police fell foul of confirmation bias. In simple terms, that means senior officers had already reached a decision and were looking for intelligence to justify it. The list of errors and inaccuracies set out in an independent review of the decision-making that led to fans of Israeli football club Maccabi Tel Aviv being banned from attending a fixture at Villa Park in November have been described by Mahmood as damning. They include: A report of a football match in an intelligence report produced using AI which never happened; a twice-repeated denial by senior police leaders to MPs that AI had not been relied on to produce the inaccurate report; the claim that local Jewish groups had been consulted on the move when they had not been; inaccurately presenting evidence from Dutch police reports from a previous fixture involving the club.

Over 11 years, citizen scientists collected billions of data signals for the SETI@home project. Breakthroughs, discoveries, and DIY tips sent six days a week. After reviewing almost 30 years of signals, University of California Berkeley researchers have identified 100 mysterious, deep-space radio blips they want to review for signs of extraterrestrial life . And they couldn't have done it without 11 years of volunteer work from millions of PC owners around the world. Even with today's advanced computers, the world's most complex data problems can't be solved by a single machine.

'Appropriate and unambiguous': White House defends Trump over middle-finger gesture at heckler The White House has defended US President Donald Trump after he aimed an offensive gesture at a heckler during his appearance at a Ford factory in Detroit on Tuesday. Footage of the incident published by TMZ appears to show the president responding to a man who shouted at him from afar. The White House said: A lunatic was wildly screaming expletives in a complete fit of rage, and the President gave an appropriate and unambiguous response. The heckler has been suspended by Ford, the United Auto Workers union told the BBC's US partner, CBS News. A Ford spokesperson told CBS: One of our core values is respect and we don't condone anyone saying anything inappropriate like that within our facilities.

China announced record export numbers for 2025, a year when US President Donald Trump's tariffs and trade policy caused turmoil in the global economy. Beijing on Wednesday reported the world's largest-ever trade surplus - the value of goods and services sold overseas compared to its imports - at $1.19tn (£890bn). It's the first time China's full-year trade surplus has passed $1tn, beating 2024's record figure of $993bn. China's monthly export surpluses passed $100bn seven times last year - a sign that Trump's tariff campaign have barely affected its overall trade with the rest of the world. Trade with the US did weaken, but this was made up for by a rise in Chinese exports elsewhere, especially to South East Asia, Africa and Latin America.

You must have heard of Dubai chocolate: the sticky, indulgent confectionary filled with pistachio cream, tahini and shreds of knafeh pastry, which has become a global sensation. Now the decadent bar has inspired South Korea's latest dessert craze. The Dubai chewy cookie has been selling like wildfire - and even restaurants that don't usually offer baked goods are trying to get a nibble of the market. Despite its name, the cookie's texture more closely resembles a rice cake, and is made by stuffing pistachio cream and knafeh shreds into a chocolate marshmallow. Shops are selling hundreds of cookies within minutes and the frenzy has sent prices of key ingredients surging, local media reported.

The chef behind Wales' only two-Michelin-star restaurant has said he is not embarrassed after it was awarded a one-star hygiene rating. Ynyshir Restaurant and Rooms, near Machynlleth in Ceredigion, which charges nearly £500 per head, received the rating after a visit by food safety officers on 5 November. According to the Food Standards Agency (FSA), a score of one out of five means major improvement is necessary. But chef patron Gareth Ward, a contestant on MasterChef The Professionals, said the restaurant was working at the highest standard in the world and doing something different with how it approaches raw ingredients and techniques. Ynyshir offers a high-end dining experience starting at £468 per person, including a 30-course tasting menu and an in-house DJ.
