This week's Pathological programme brings you a glimpse into the world of the pathologist. We attend a real autopsy to discover how a pathologist uncovers a cause of death, and hear how Cambridge scientists have found a new way to stop Multiple Sclerosis (M.S.) in it's tracks. We also find out how a common rock can lock away carbon, why forest fungi give out less greenhouse gases when they're warm, and shed some light on the workings of world's smallest solar panels. Plus, in place of Kitchen Science, Ben tries to stop a virtual outbreak of the plague!
