Scientists Pioneer Surgical Methods for Human Head and Eye Transplants

Episode 388 Two extraordinary breakthroughs have been made in transplant surgery. First, scientists have found a way of keeping human eyes alive for up to 10 hours after death, opening up the possibility of eye transplants in the future. And in a second controversial surgery, another team has managed to restore severed spinal cords in pigs, allowing them to walk again after being paralysed. While it’s hoped this will eventually allow people with spinal injuries to walk again, one of the scientists involved is a proponent of human head transplants - or body transplants as they should really be known. Is that the ultimate goal? Find out how the scientists achieved these feats - and what’s required to take both surgeries to the next level. Rowan Hooper and Penny Sarchet are joined by Alexandra Thompson. To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices. Visit megaphone.fm/adchoices
