Mutating monarchs, app eye scans and tsunami fungi

Science commentator Siouxsie Wiles joins Kathryn to talk about the three mutations it can take for Monarch butterflies to feed on poisonous milkweed and use the poison on its predators. She'll also look at a smartphone app that can scan everyday family photos to check for eye disease in kids, and a new study which suggests contaminated shipping ballast and a tsunami moved a deadly fungus from the temperate forests of the Pacific Northwest right up to Alaska. Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
