Ian Connellan, Editor in chief of The Royal Institution of Australia, joins John Stanely to chat about the latest science stories.

This week John discovers how psychedelic therapies have the potential to treat mental illness.

Ian explains how until now, the earliest evidence of humans cooking dates to around 170,000 years ago, but now new evidence suggests a huge carp-like fish, two metres in length, found in Israel, shows that fish were cooked roughly 780,000 years ago, meaning the earliest signs of controlled fire cooking began earlier than we initially thought.
