Removing tonsils & the ancient art of trepanning

Science commentator Siouxsie Wiles reports on the link between removing tonsils and adenoids in childhood and the long-term risk of respiratory, allergic and infectious diseases; the case of a young man who had a stroke that they think was linked to his use of synthetic cannabis, a prototype harvester to extract water from the air is scaled up and taken to Arizona, and a neurologist has been comparing how the ancient Peruvians and more modern day Americans fared after being trepanned. Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
