Dear Science: Piss in pools, psychic nonsense, and an overreaction to an alleged mercury ‘reaction’

This week on Dear Science, we have AUT’s Allan Blackman joining us to talk about some of the latest in science news. He talks to Ximena about a new test in Canada that reveals how much urine is really in public pools, a false alarm to evacuate a Hastings school earlier this week, and also about the tragic return of New Zealand prime time television show, Sensing Murder.
