This week, Claire reveals the surprising observation of parthenogenesis, aka 'virgin birth', in the endangered California condor (Gymnogyps californianus), and explains how this is possible, and why the chicks are male thanks to bird sex chromosomes being different from ours; and Stu dives into the alkaline water fad, why it won't help your health, and why the way a certain celebrity uses it makes even less sense.
Chris Lassig, Stuart Burns and Claire Farrugia and others.
