Description:
In this episode, hunt for shark's teeth with Bretton Kent, Ph.D., who is studying the teeth to learn more about the feeding habits of sharks. He is hoping to learn how current shark populations live and hunt by studying those that are extinct. Then meet researchers, Avis Cohen, Ph.D., and Ralph Etienne-Cummings, Ph.D., who are working on a joint project that will eventually help those with spinal cord injuries. Cohen is studying the movements and spinal regeneration in the lamprey eel and Etienne-Cummings is using Cohen's data to produce computer chips, that when placed in a robot, actually mimic human movement. Speaker(s):
Andrew Wolvin, Ph.D., professor, Communication, University of Maryland
