From genetics to cosmology to nanotechnology, science is on the brink of numerous and extraordinary mega-revolutions that will change the very nature of life.  Closer to Truth brings together leading scientists, scholars and artists to debate many of today’s fundamental issues. Today's top scientists and social experts discuss a topic that is at once ultimately private and excessively public. They offer insight into our society's sexual norms and discuss why and how a new kind of 'sex therapy' may offer help to many. Joining host Robert Kuhn are sex therapists Cliff and Joyce Penner; best-selling author and surgeon Sherwin Nuland; human sexuality authority Paul Abramson; and medical historian Vern Bullough.
