This scientist rewarmed and studied pieces of his friend’s cryopreserved brain

Gerontologist L. Stephen Coles had his brain cryopreserved at Alcor after his death in 2014 and asked cryobiologist Greg Fahy to study it. Fahy recently analyzed samples and found the brain 'astonishingly well preserved,' though other scientists remain skeptical about reanimation. While reviving cryopreserved humans remains science fiction, the research could advance organ preservation for transplantation.
