Chappell Roan fans will soon be able to transform into the US pop star when playing the video game Fortnite. The singer has been announced by developers Epic as the latest icon for the game's next festival season, which kicks off on Thursday. As part of collaboration, players will be able to wear some of the singer's most iconic outfits and listen to some of her hit songs. The collaboration comes after Roan told BBC Radio 1 last year that she would love to feature in the game. During the interview with Radio 1 presenter Jack Saunders, the singer professed her love for the video game and asked the developers: Please give me a skin, please.

Oscar-winning actress Cate Blanchett and former prime minister Baroness Theresa May are among the six public figures who will guest edit BBC Radio 4's Today programme over the Christmas period. Broadcaster Melvyn Bragg, historian and podcaster Tom Holland, inventor Sir James Dyson and Microsoft's head of artificial intelligence (AI) Mustafa Suleyman will also guest edit shows between 24 December and 31 December. For the past 22 years, the news programme has handed over the editorial reins to guest editors during the festive period. Owenna Griffiths, editor of Today, said: In a rapidly changing world, this year's guest editors will help bring illumination and understanding. She added: Every Christmas on Today, a new set of guest editors take up residence and bring with them a wonderful range of new stories, fresh ideas and, hopefully, a sprinkling of joy.

Artificial intelligence (AI) was centre stage at the World Economic Forum in China. At least 20 of the 56 companies selected for the organisation's Technology Pioneers programme are using AI in some way with applications ranging from autonomous vehicles to advertising technology. A branch of AI, machine learning, is dedicated to the ability of a machine to learn something without having to be programmed for that specific thing. It enables computers to improve their performance automatically over time by being fed data and information in the form of observations and real-world interactions – like a toddler learning about the world around them. Answering whether the animal in a photo is a cat or a dog, spotting obstacles in front of a self-driving car, spam mail detection, and speech recognition of a YouTube video to generate captions are just a few examples out of a plethora of predictive machine learning models.

BBC Radio 1 has announced a major overhaul of its line-up, with the weekend schedule now starting on Fridays. Nick Grimshaw, Clara Amfo and Greg James will go down to hosting four shows a week as a result. New Friday shows have been announced for Maya Jama and The Saturdays' Mollie King as part of the changes, and Scott Mills will now host the chart show. Dev and Alice Levine will present the breakfast show from Friday to Sunday. Ben Cooper, controller of BBC Radio 1, said: "The weekend will start here at Radio 1 on a Friday morning giving our young audience that feel-good factor a day early. "It's our job at Radio 1 to reinvent the way young people listen to the radio, to disrupt traditional thinking and to look for new ways in which to grow audiences." The new schedule comes into effect in June. It's unclear how the schedule changes might affect the daytime hosts' current salaries, but a BBC spokesman said all presenters on the station are paid fairly. This marks the first time in Radio 1's history that the daytime DJs will be on a four-day week, although Chris Evans once tried to take Fridays off when he was hosting the breakfast show. In the late 1990s, he famously asked if he could host the programme only from Monday to Thursday - a request which was denied by then-controller Matthew Bannister. Jama joined the station earlier this year as the presenter of Radio 1's Greatest Hits. King has been appearing as a guest presenter with Edmondson in recent weeks but will now officially be a permanent fixture on the station. The singer, who appeared on the most recent series of Strictly Come Dancing, said: "I've grown up listening to Radio 1 and I can't wait to be one of the team.
