Life After Ice: 46,000-Year-Old Worms Wake Up

Описание: In this SETI Live episode, host Simon Steel (Deputy Director of the Carl Sagan Center) chats with evolutionary biologist Philipp Schiffer (Worm Lab) about one of the most astonishing discoveries in modern biology: scientists have revived a microscopic worm that had been frozen in Siberian permafrost for roughly 46,000 years. These nematodes entered a state of cryptobiosis — a kind of biological “pause” — and came back to life when gently thawed in the lab. They didn’t just wiggle; they fed, reproduced, and gave us a window into life’s extreme resilience.

Simon and Philipp dive into the role of cryptobiosis, how radiocarbon dating places these organisms back in the late Pleistocene when woolly mammoths roamed, and what it means for the limits of suspended animation. This is biology meeting deep time — and you’re invited to stretch your imagination along with the science.
