Putting organs into the deep freeze, a scavenger hunt for robots, and a book on race and reproduction

On this week’s show: Improvements in cryopreservation technology, teaching robots to navigate new places, and the latest book in our series on sex and gender   First up this week on the show, scientists are learning how to “cryopreserve” tissues—from donor kidneys to coral larvae. Contributing Correspondent Warren Cornwall joins host Sarah Crespi to talk about the latest in freezing and thawing technology.   Next up: How much does a robot need to “know” about the world to navigate it? Theophile Gervet, a Ph.D. student at Carnegie Mellon University, discusses a scavenger hunt–style experiment that involves bringing robots to Airbnb rentals.   Finally, as part of our series of books on sex, gender, and science, host Angela Saini interviews author Dorothy Roberts, a professor of law and sociology at the University of Pennsylvania, about her book Killing the Black Body: Race, Reproduction, and the Meaning of Liberty.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Angela Saini; Warren Cornwall   Episode page: https://www.science.org/doi/10.1126/science.adj4684   Learn more about your ad choices.
