This week we're seeking the science of laughter and music. We're speaking to comedian Robin Ince about how geneticists and astronomers can inspire stand up comedy, listening to the music of the world's first online science music festival, and genetically profiling comedienne Kathryn Ryan. We also get the giggles to find out what happens in your brain to make laughter so addictive. Plus, we'll follow the footprints of human evolution, find out how Jupiter and Saturn acted as celestial bulldozers, and discover how a cheeky octopus left an aquarium knee deep in water!
