A trio linked with a US technology supplier have been charged over a ploy to smuggle American artificial intelligence (AI) chips to China, the Department of Justice said on Thursday. The individuals allegedly conspired to sell billions of dollars' worth of technology to buyers in China by faking documents and using dummy equipment to slip past audits, according to the DOJ. The goods in question included Nvidia-made semiconductors, highly coveted AI chips which are subject to export controls. In August 2025, two Chinese nationals were also arrested and charged with illegally shipping millions of dollars' worth of Nvidia chips to China. The DOJ said in a statement on Thursday that it had arrested US-citizen Yih-Shyan Wally Liaw and Taiwanese citizen Ting-Wei Willy Sun, while Ruei-Tsang Steven Chang, a Taiwanese citizen, remains a fugitive.

The return of BTS is a big deal. In case you were in any doubt, just look at the frenzy surrounding the South Koreans' comeback. On Saturday, the band will kick off a sold-out, 82-date world tour with a free concert in Seoul, which is expected to be attended by more than 250,000 in-person fans and will be live-streamed on Netflix to more than 190 countries. When the tour wraps up in 2027, BTS are expected to have generated more than $1billion in revenue. Some more outlandish estimates suggest they will eclipse the $2billion haul of Taylor Swift's Eras tour.

Ros Atkins on... Trump's mixed messages on the war For every day of this war, President Trump has been sharing his perspective and his thinking - whether in press conferences, in video statements or in posts on social media. In the last week, that's continued - as strikes have been exchanged - and pressure has built on the supply of oil and gas from the region. The BBC's Analysis Editor Ros Atkins has looked at what the President's been saying.

Video game fans and big, blockbuster releases have had an uneasy relationship in recent years. As so-called triple-A games get more expensive to make, the publishers behind them are accused of taking fewer risks and failing to try new things. But highly anticipated new release Crimson Desert asks a different question - what if a big-budget, graphically advanced game tried to do absolutely everything? The ambitious action-adventure's been compared to a buffet, presenting players with a smorgasbord of ideas, gameplay styles and quests to gorge on. While some have praised it as a feast, others have found it overstuffed, with some undercooked morsels behind the impressive presentation.

US rapper Afroman has defeated seven sheriff's deputies in a court case after they sued him for releasing songs and videos that mocked them and a raid they carried out on his home. The officers broke down the musician's door in 2022 as part of a drug and kidnapping investigation, but the raid didn't lead to any charges. Afroman, best known for his 2000 hit Because I Got High, responded by using home security footage in viral videos that ridiculed the deputies. His video for the song Lemon Pound Cake was inspired by a deputy apparently eyeing a cake in his kitchen, while another video attributed personal and sexual transgressions to the officers. They sued him for defamation, but a jury has sided with the colourful rapper after a three-day trial. Afroman yelled outside the Ohio court, surrounded by supporters, in a clip posted on social media after the verdict.

Despite being declared the third-hottest year on record, 2025 was a relatively quiet year for climate disasters in the US. No major hurricanes made landfall, while the total number of acres burned in wildfires last year--a way of measuring the intensity of wildfire season --fell below the 10-year average. But starting this week, the West is experiencing what looks to be a record-breaking heat wave, while forecasting models predict that a strong El Niño event is likely to emerge later this year. These two unrelated phenomena could set the stage for a long stretch of unpredictable and extreme weather reaching into next year, compounding the effects of a climate that's getting hotter and hotter thanks to human activity. Beginning this week and heading into next, a massive ridge of high-pressure air will bring record-breaking temperatures to the American West.

Amazon's Alexa has had an AI upgrade. Now she's got more to say Amazon's Echo smart speaker - more commonly known as Alexa - is getting an AI-powered upgrade which will roll out across the UK. Alexa+ turns the digital assistant into a more chatty device which Amazon says will be able to follow threads and be more proactive in its responses. There has been criticism the Echo has stagnated since its launch in 2016, while AI chatbots like ChatGPT, Gemini and Claude have become much easier to communicate with. It will be interesting to see how users react to this - we expect this could be polarising, with some enjoying the more relaxed, familiar interactions while others may find it disconcerting, said Jessica Miller, head of data insights at FDM/CCS Insight. UK consumers will notice an immediate difference, she added.

Humour and science fiction may not seem obvious bedfellows but a history of cinema will tell you different. Think Spaceballs, Mars Attacks! and Everything Everwhere All At Once to name but a few. And now Ryan Gosling is hopping on board. The 45-year-old is both the lead actor and producer of Project Hail Mary, a space adventure film based on the 2021 Andy Weir novel of the same name. While Gosling has showcased his comedy chops in films such as Barbie and Nice Guys, he tells the BBC he's always struggled as an actor because I would want to bring humour to something but has found opportunities to be funny limited with some projects.
