Hot to Cold

There are benefits to chilling out. When we cool superconductors to 460℉ degrees below zero, they acquire extraordinary properties that help run quantum computers. Can artificially cooling human bodies also provide profound benefit? Some cryonics startup companies say yes, promising “life after death” through cryogenic freezing. While it’s one thing to freeze all the cells in a body, it is another to revive them. What happens, for instance, to memories when brains thaw? While we gauge how low human body temperatures can go, new research suggests another form of life could find home in the cooler temperatures of Jupiter’s moon Europa. Find out how NASA’s Europa Clipper mission will investigate whether that moon could support alien microbes. Guests: Steve Austad – Distinguished Professor at the University of Alabama at Birmingham and Scientific Director of the American Federation for Aging Research Olivia Lanes – Global Lead for Quantum Content and Education at IBM Quantum Austin Green – Post doctoral research associate at Virginia Tech University, and former JPL postdoctoral fellow and affiliate scientist on Europa Clipper Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.
