Exploring Genetic Variants and the Possibility of Life on Ceres

Twenty years ago, Hurricane Katrina made landfall in Louisiana, and the levees designed to protect New Orleans failed. Huge swaths of the city flooded, and 1,600 people were trapped inside Charity Hospital. Physician Erica Fisher was working in Charity’s emergency room at the time, and she and her colleagues fought for days to keep their patients alive.

Host Flora Lichtman speaks with Dr. Fisher, now an emergency medicine physician at University Medical Center in New Orleans, about Hurricane Katrina and the vulnerability of our healthcare systems in the face of disasters.

Plus, science writer Maggie Koerth joins Flora to share other science news the week, including the link between heat waves and aging, updated COVID vaccine guidelines, the ancient origins of human mucus, and the possibility that dwarf planet Ceres could once have sustained life.

Guest: Dr. Erica Fisher is an emergency medicine physician at University Medical Center in New Orleans, Louisiana.
