Flesh eating bacteria update, not-so-rare earth metals, PFAS in the water

This week Claire updates us on the flesh-eating Buruli ulcer epidemic and research into how it's spread; Stu tells us all about rare earth metals that are used in modern technology and how they're not so rare any more; and Chris looks at the PFAS chemicals behind the water contamination in Bundaberg and other places in Australia (for updates see www.bundaberg.qld.gov.au/pfas).
