Science down under

This week the Unexpected Elements team has travelled Down Under to sunny Sydney where we discover some wonderfully Australian science with the help of some wonderfully Australian panellists. First, we discuss the surprising American origins of Australia’s iconic marsupials and Marnie gets up close and personal with Pez the Tasmanian Devil. We also talk to Andy Flies from the University of Tasmania who is working on a vaccine to combat a deadly contagious cancer spreading through Australia’s Devil population. Next, we’re joined by Susan Sawyer from the University of Melbourne as we delve into the debate surrounding Australia’s social media ban for under 16-year-olds. Are the kids alright? Plus, we find out about the tree that seems to be adding fuel to the country’s recent wildfires. All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Katie Silver and Jonathan Webb Producers: Margaret Sessa-Hawkins, with Ella Hubber, Sophie Ormiston and Lucy Davies
