Researchers have found a way to reverse the ageing of human cells by 30 years. They tried a new technique on human skin cells, and managed to partly restore the function of older cells, while renewing their biological age at the same time.

London Zoo is using jumping spiders to try to help people overcome their arachnophobia. The neon-coloured spiders can leap six-times their body length.

Plus, Activision Blizzard is giving a thousand game testers full-time jobs, a dinosaur specialist explains the significance behind the North Dakota asteroid fossil site, a post mortem of ‘extraordinary’ Greenland shark reveals it had meningitis, the new Snapchat lens that can teach you sign language, and Returnal is named best game at Bafta Games Awards.
