Get festive with the Naked Scientists at the Cambridge Science Festival! We sniff out the sizzling science of our food, explore the workings of a mobile phone and hear the songs of the Cavendish Society for the first time since the 1930s. Plus, insights into the neurological basis of dyslexia, toxic airborne copper dust and paint that heals its own scratches. Dr Ben Goldacre joins us to explain why abuse of statistics could make you a suspected terrorist or falsely suggest you have HIV. In Kitchen Science, Dave plugs a pickled gherkin into the national grid!
