The Download: the dream of cryonics, and enhanced rats


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.

Why the sci-fi dream of cryonics never died

When Aaron Drake flew from Arizona to the Yinfeng Biological Group in China in 2016, he was traveling there to guide China’s first forays into cryonics, or freezing corpses for reanimation.

Drake had spent the previous seven years as the medical response director of the Alcor Life Extension Foundation, a small nonprofit that had managed to become the longtime leader in cryonics, freezing the bodies and brains of its members, with the idea of one day bringing them back to life, since 1976.

The foundation, and cryonics in general, had long survived outside of mainstream acceptance. But it’s the recent involvement of Yinfeng that signals something of a new era for cryonics.

With impressive financial resources, government support, and scientific staff, it’s one of a handful of new labs focused on expanding the consumer appeal of cryonics and trying anew to bring credibility to the long-disputed theory of human reanimation. Still, the field remains rooted in faith rather than any real evidence that it works. Read the full story.

Are rats with human brain cells still just rats?

This week, my colleague Jessica Hamzelou wrote about a fascinating experiment that involved implanting human brain cells into rats’ brains. The brain cells from both species were able to form connections and work together. The human cells became part of the rats’ brains.

A few months after they’d been implanted, the human cells made up around a sixth of the rats’ brains and appeared to have a role in controlling the animals’ behavior. Which invites the tricky question: Are these animals still 100% rat? Read the full story.
