One Scientist's Search For Microbial Life In Extreme Places

Karen Lloyd is no stranger to life in the extremes: she has encountered super-resilient microbial life near volcanoes, on the ocean floor, and deep in the crust of the Earth. Some of these microbes can survive extreme temperatures, "breathe" minerals like gold, or even live for thousands of years. In this episode of Constant Wonder, learn about how extraordinary life on Earth can be. Guest: Karen G. Lloyd, Wrigley Chair in Environmental Studies, Professor of Earth Sciences, and Professor of Marine and Environmental Biology at the University of Southern California; author of "Intraterrestrials: Discovering the Strangest Life on Earth"
