Zurich-based firm taps into latest robot tech to'fibre-spray' high-end sports shoes worn by the likes of Roger Federer A robot leg whirs around in a complex ballet as an almost invisible spray of "flying fibre" builds a hi-tech £300 sports shoe at its foot. This nearly entirely automated process - like a sci-fi future brought to life - is part of the gameplan from On, the Swiss sports brand that is taking on the sector's mighty champions Nike and Adidas with a mix of technology and chutzpah. The brand is expanding rapidly after teaming up with the former tennis pro Roger Federer to create shoes suitable for the Swiss star's sport and a mix of fashion-led collaborations including with the luxury brand LOEWE, actor Zendaya and singers FKA twigs and Burna Boy. In China, sales have doubled year-on-year. Growth has been strong in the US and mainland Europe and this month On will open its fourth London store, in Kensington.

Laguna Beach High School administrators have launched an investigation after a student allegedly created and circulated "inappropriate images" of other students using artificial intelligence. It is not clear how many students are involved in the scandal, what specifically the images contained or how they were distributed. In an email to parents on March 25, Principal Jason Allemann wrote that school leadership is "taking steps to investigate and directly address this issue with those involved, while also using this situation as a teachable moment for our students, reinforcing the importance of responsible behavior and mutual respect." The Laguna Beach Police Department is assisting with the investigation, but a department spokesperson declined to provide any details on the probe because the individuals involved are minors. The Orange County high school joins a growing number of educational institutions grappling with the use of artificial intelligence in the classroom and in social settings.
