The Download: reawakening frozen brains, and the AI Hype Index returns | MIT Technology Review

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. This scientist rewarmed and studied pieces of his friend’s cryopreserved brain  L. Stephen Coles’s brain sits in a vat at a storage facility in Arizona. It has been held there at a temperature of around −146 degrees °C for over a decade, largely undisturbed. Before he died in 2014, Coles had the brain frozen with an ambitious goal in mind: reanimation.  His friend, cryobiologist Greg Fahy, believes it could be revived one day. But other experts are less optimistic.   Still, Fahy’s research could lead to new ways to study the brain. And using cryopreservation for organ transplantation is becoming a viable reality.   Read the full story to find out what the future holds for the technology.  —Jessica Hamzelou  The AI Hype Index  Separating AI reality from hyped-up fiction isn’t always easy. That’s why we’ve created the AI Hype Index—a simple, at-a-glance summary of everything you need to know about the state of the industry.
