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.

X CEO Elon Musk has said he was not aware of any "naked underage images" generated by xAI's Grok chatbot, as scrutiny of the AI tool intensifies worldwide. "I [am] not aware of any naked underage images generated by Grok. Literally zero," Musk said in an X post on Wednesday. Musk reiterated that Grok is programmed to refuse illegal requests and must comply with the laws of any given country or state. "Obviously, Grok does not spontaneously generate images, it does so only according to user requests," Musk said.

'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.

Environment Animals Wildlife 14,000-year-old woolly rhinoceros DNA extracted from wolf's stomach The two-horned prehistoric mammal went extinct about 8,700 years ago. Breakthroughs, discoveries, and DIY tips sent six days a week. Towards the end of the last ice age, an ancient wolf feasted on a young woolly rhinoceros (). When the wolf died, it ended up buried in Siberian permafrost for about 14,000 years until it was uncovered by paleontologists in 2015. Luckily for scientists, some woolly rhinoceros tissue remained inside of the wolf's stomach.

The popularity of commercial nuclear reactors has surged in recent years as worries about climate change and energy independence drowned out concerns about meltdowns and radioactive waste. The problem is, building nuclear power plants is expensive and slow. A new generation of nuclear power technology could reinvent what a reactor looks like--and how it works. Advocates hope that new tech can refresh the industry and help replace fossil fuels without emitting greenhouse gases. Here's what that might look like . Next-gen nuclear is one of our 10 Breakthrough Technologies this year.

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.
