We explore the explosive science of volcanoes this week! We find out what you can learn from drilling into a restless volcano, how gravity is used to "weigh" volcanoes and watch them fill with magma, and we explore the theories behind volcano formation. Plus, we hear about the genes that could mean you'll live to be 100, fossil evidence of the earliest multi-cellular organism and the signs that Sabre-toothed tigers packed a mighty punch, as well as a big bite. In Kitchen Science, we get messy with a cola and wallpaper paste eruption! Like this podcast? Please help us by supporting the Naked Scientists
