Cool Science Radio - October 29, 2015

Dr. Leslie Knapp, professor and chair of Anthropology Department at University of Utah kicks off the show with hosts Lynn Ware Peek and John Wells. She is author of the scientific paper, Evolutionary Trade-off between Vocal Tract and Testes Dimensions in Howler Monkeys Across the animal kingdom, males hoot and holler to attract females and ward off competing suitors. Now, a new study finds that male howler monkeys with deeper calls have smaller testicles – and vice versa, according to researchers from universities of Utah, Cambridge and Vienna.

Next on the program is Erin E. Murphy, author of Inside the Cell: The Dark Side of Forensic DNA. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Murphy exposes the dark side of forensic DNA testing.
