Frozen Brain Fragments Raise Hopes and Questions About Revival
Biogerontologist L. Stephen Coles’ brain was cryopreserved after death and stored for over a decade at -146°C. Greg Fahy later biopsied the preserved tissue and found the fragments to be surprisingly well preserved, suggesting future studies might learn from the brain; however, experts caution the brain is not alive and revival remains unproven, with a peer‑reviewed report still forthcoming.
