The Science Hour

Record high gold prices have us looking at the science of inflation, why gold is leaking from volcanoes, and entomologist Katy Price explains why shiny gold can be a good color for camoflague. Plus the dark science going on in a gold mine, whether we can move at the speed of light, and the debate around golden rice. All that, plus more unexpected elements.Presenter: Marnie Chesterton Producers: Alice Lipscombe-Southwell, with Margaret Sessa-Hawkins, Robbie Wojciechowski and Lucy Davies.
