Scientists have achieved a net energy gain in nuclear fusion for the second time, marking major progress towards realising the potential of the near-limitless energy source. A team at the Lawrence Livermore National Laboratory in California, who first achieved the feat last December, claimed to have passed a new milestone with fusion ignition by producing even greater energy output than the original experiment. The nuclear fusion process has been described as the “holy grail” of clean energy, as it requires no fossil fuels and leaves behind no hazardous waste. Instead it mimics the natural reactions that occur within the Sun, though harnessing its potential has puzzled scientists since the 1950s. Achieving nuclear fusion ignition is a crucial step towards building commercial power stations, though the technology needs to be significantly scaled up from the current experiments for it to be a viable energy source. The first ever successful fusion energy gain experiment on 5 December, 2022, used lasers to fuse two light atoms into a single one, releasing 3.15 megajoules of energy from 2.05 megajoules of input. Researchers described the milestone as “one of the most significant scientific challenges ever undertaken by humanity” that would “enable the next steps toward clean fusion energy for the future”. Scientists that were not involved in the fusion experiments said the advance had profound implications for the future of the planet. “We are witnessing a moment in history: controlling the power source of the stars is the greatest technological challenge humanity has ever undertaken,” said physicist Arthur Turrell. “This experimental result will electrify efforts to eventually power the planet with nuclear fusion – at a time when we’ve never needed a plentiful source of carbon-free energy more.” A spokesperson for the Lawrence Livermore National Laboratory said the final results of the latest experiment are still being analysed. The lab plans to present the results at upcoming scientific conferences and in peer-reviewed journals. Several companies are already investing heavily in nuclear fusion, with Microsoft making the world’s first purchase agreement earlier this year. The US tech giant made the deal with Helion Energy, which aims to set up a nuclear fusion power plant within the next five years despite the challenges remaining to make it commercially viable. Helion chief executive David Kirtley said at the time: “We still have a lot of work to do, but we are confident in our ability to deliver the world’s first fusion power facility.” Read More Superconductor breakthrough could represent ‘biggest physics discovery of a lifetime’ – but scientists urge caution Microsoft makes world first nuclear fusion energy deal Zuckerberg says he is ‘ready today’ but ‘not holding breath’ for cage fight with Musk Musk pledges to fund legal bills of X users ‘unfairly treated’ by employers for posts Scientists want to hack the planet to cool it down.

Gov Ron DeSantis’ campaign has been accused of using fake, AI-generated images of former President Donald Trump hugging ex-White House chief medical adviser Anthony Fauci in an attack ad. Mr DeSantis and Mr Trump have been trading barbs for weeks about their respective Covid responses, with Mr Trump’s campaign and surrogates arguing that Mr DeSantis’ initial lockdown measures in Florida were too harsh and Mr DeSantis’ campaign arguing that Mr Trump was too acquiescent to medical professionals like Dr Fauci in crafting his administration’s response. Now, in the ad shared by the the “DeSantis War Room” Twitter account, the Florida governor’s campaign is accused of crossing an ethical line. The adveritsement begins with clips of Mr Trump firing people on his reality television show before pivoting to clips of Mr Trump telling reporters that he would not or could not fire Dr Fauci, who was seen as the symbol of a public health response to the crisis some Republicans disagreed with. Towards the end of the ad, the screen shows a split with six images of Mr Trump and Dr Fauci — three of which experts believe were generated by artificial intelligence. AFP first reported the presence of the allegedly fake images. The three images experts believe are fake are located in the top left, bottom centre, and bottom right of the screen. All of them feature Mr Trump and Dr Fauci embracing and cannot be found elsewhere on the internet, a sign that they may be AI-generated. There are other signs as well. The Verge noted that the potentially AI-generated images are glossier and have more blurred textures than the other images and show Mr Trump and Dr Fauci in physically improbable poses. The reproduction of the White House press briefing room in one of the images also looks unrealistic. Hany Farid, a professor at the University of California, told the AFP he believed it is “highly likely” that the images are fake. The Independent has reached out to the DeSantis campaign for comment. So far, the DeSantis campaign is not exactly denying those allegations. After The Verge’s story was published, DeSantis aide Christina Pushaw tweeted an image Mr Trump had put out of Mr DeSantis on a rhinoceros and wrote “I think this might be an AI-generated image. Who knows?” Mr Trump has indeed used AI several times in recent months, including posting a deep fake mocking Mr DeSantis’ presidential campaign launch. “No campaign has pushed more misleading deepfakes, false photoshops, and outright fabrications than the Trump campaign,” Matt Wolking, a spokesperson for the DeSantis-aligned Never Back Down PAC, told The Verge. “It is 100% true that Donald Trump empowered and embraced Fauci — he even gave him a presidential commendation.” Read More Ivanka and Jared split over attending Trump 2024 launch – follow live Why was Donald Trump impeached twice during his first term?
