Following recent coups in Niger and Gabon, and with seven African coups in the last three years, some political commentators are suggesting that there might be an epidemic of coups. But are coups really contagious, and what does the political science say?
Caroline Steel and the Unexpected Elements team across three different continents go on a quest to find the science lurking behind the news.
We find out what trees in Chile can tell us about coups and we meet the wasp that performs a coup on a poor unsuspecting cockroach, turning it into a zombie and eating it alive.
There’s light relief in the form of cows listening to classical music, the answer to a listener question about carbon capture and reflections on efforts to rid the world of plastic bags.
All that plus your emails, whatsapps, and more fruit chat than you can shake a banana skin at.
