For this Radiothon special, Dr Shane is joined by special guests from the Radiotherapy and Radio Marinara shows: Kent Goldsworthy aka Panel Beater and Bron Burton. Bron shares findings from her PhD studies on intertidal limpets and how they can represent the impact of human activities upon intertidal ecology. In the studio are also Scarlett and Chris KP with some science news about why we actually yawn, and how it's related to ice-cream brain freeze. Serving Up a Sonic Soup!
