The tech behind the Olympics: High-speed cameras, sensors, and annoying drones

Popular Science

Sports pushes the science of keeping time forward. A broadcast drone hovers as Britain's Makayla Gerken Schofield competes in the freestyle skiing women's moguls. Breakthroughs, discoveries, and DIY tips sent six days a week. Athletes competing in this year's Winter Olympic Games in Milan will do so surrounded by a complex web of AI-enabled cameras, stopwatches, sensors, and fast-flying drones capable of tracking performance down to fractions of a second. The high-tech timekeeping system, the culmination of nearly a century of constant iteration, is fundamentally reshaping how viewers at home experience the Games.

Twelve men charged with manslaughter of football fan

BBC News

Twelve men have been charged with the manslaughter of football fan Simon Dobbin. Dobbin was assaulted outside the Railway Tavern in Southend-on-Sea in Essex in March 2015 following a match between Cambridge United and Southend United. The dad from Mildenhall, Suffolk, died in October 2020 after suffering a brain injury as a result of the attack. The Crown Prosecution Service (CPS) said it had now decided to prosecute 12 men in connection with his death and all the defendants will appear at Colchester Magistrates' Court on 31 March. Rebecca Mundy, deputy chief crown prosecutor, said the CPS had worked closely with Essex Police to examine and review material obtained during previous investigations.
