The Covid curve, caterpillar plastic eaters

Science commentator Siouxsie Wiles updates Kathryn on developments with Covid-19 - and why we all need to help flatten the Covid curve. She'll also look at how the beeswax-melting digestive system of a caterpillar could hold the secret to solving plastic pollution, after researchers fed plastic bags to wax moth larvae and discovered some of their gut bacteria thrived on the unusual diet. She'll also look at a study of over 30 different species of amphibians and found many emitted a fluorescent glow after absorbing light. Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
