The Infinite Monkey Cage returns in the first of a new series and turns its gaze on the science of risk.

Professor Brian Cox and comedian Robin Ince bring their witty and irreverent take on the world to a programme all about the science of risk. Together with guests David Spiegelhalter, Sue Ion and former Goodie, Graeme Garden, the team explores such questions as: why is seven the safest age to be? Should badgers wear bicycle helmets? How safe is nuclear power and how worried should we be by the threat of asteroid impact? Producer: Rami Tzabar.
