We’re on Radiolab! Hudson Freeze, PhD, director of the Sanford Children’s Health Research Center joins the legendary science podcast to recount a discovery that changed biology forever.

For years, scientists thought nothing could live above 73℃/163℉.At that temperature, everything boiled to death. But scientists Tom Brock and Hudson Freeze, PhD, now director of the Sanford Children’s Health Research Center and William W. Ruch Distinguished Chair at Sanford Burnham Prebys, weren’t convinced.

What began as their simple quest to trawl for life in some of the hottest natural springs on Earth would, decades later, change the trajectory of biological science forever, saving millions of lives.

Listen to Freeze recount a transformative moment in his early career on the latest Radiolab podcast.
