Scientist Studies Rewarmed Pieces of a Cryopreserved Human Brain

Cryobiologist Greg Fahy has studied rewarmed tissue from his late colleague's brain, which has been stored at −146°C for over a decade. The findings offer more promise for organ transplantation than revival of the dead.

Key Takeaways

Tissue from a cryonically preserved brain showed structural bounce-back after rewarming but no evidence of restored cellular function
The research holds more near-term promise for organ transplantation — researchers say we are near human-scale organ cryopreservation
