A new series kicks off on RTE tonight which sees Aoibhinn Ni Shuilleabhain, Kathriona Devereux and Jonathan McCrea investigate the science behind a variety of topics, beginning with fear. Aoibhinn tackles her phobia of spiders with a fairly hands-on experience, as you can see above. While Jonathan undergoes a form of waterboarding in an experiment at Trinity College Dublin to determine if stress affects the ability to recall information. Professor Shane O'Meara talks about the brain's reaction to torture and the psychology of fear, while NUI Maynooth's Dr Brian Roche reveals how fears develop and why people can become crippled by them.
