Dear Science: The underwhelming nutrition of cannibalism, the latest snake oil scam & the surprising history of chemical weapons

To match the dark and depressing weather this Wednesday, AUT’s Allan Blackman has a series of grisly & disturbing stories for Adam & Ximena. He talks through some research that looks at how prehistoric cannibalism wasn’t actually a very nutritious practice, and he also looks at ‘Te Kiri Gold’, which is the latest snake oil cancer cure desperate cancer sufferers are being scammed into buying. Finally, in light of last week’s chemical attack in Syria, he touches on the history and uses of chemical weapons, which goes back a lot earlier in history than commonly thought.
