Epilepsy affects nearly three million Americans. During this program, Charity talks with Dr. Jeffrey Noebels of the Developmental Neurogenetics Laboratory at the Baylor College of Medicine. He’ll share what he and his fellow researchers have discovered about the genes and mechanisms that underlie epilepsy and how epilepsy is related to memory. Dr. Noebels is in Iowa City to speak as part of the UI's Health Science Research Week. Later, the talk turns to the giant short-faced bear, an animal that stood more than 11 feet high and lived in Iowa during the Ice Age. A southwest Iowa farmer, Joe Walker, discovered the bones of the bear on his farm in 2008.
