Dr. Jennifer Gardy, the intrepid science sleuth, returns to CBC’s The Nature of Things with the fifth in the very popular Myth or Science series. Once again she tackles the health and science claims we all wonder about, to discover whether they’re science fact or science fiction. In this episode Gardy heads out on an international odyssey to meet an unusual group of scientists who are rewriting our understanding of how the senses really work. Although our senses are crucial to our survival, we actually know very little about them. But now there is a revolution going on. A new breed of scientists is conducting unique and sometimes bizarre experiments to trick our brain into revealing the secrets of our senses.
