When it comes to climate change, carbon dioxide usually gets the spotlight, but methane, although shorter-lived in the atmosphere, is more potent as a greenhouse gas - and levels have been mysteriously increasing. The team explains where the methane is coming from and how efforts to curb methane emissions could be important in tackling global warming. They then explore the peculiar discovery that pigs can breathe oxygen through the anus, and what that means for future applications in space travel. In coronavirus news, the team highlights the disparity between the rich and the poor in the global vaccine rollout. They also discuss the exciting arrival of a Chinese rover on Mars, and a story about the monogamous relationships of Californian mice. On the pod are Rowan Hooper, Tiffany O'Callaghan, Michael Le Page, and Adam Vaughan. Also check out the story of how the way you move can change the way you think, and how chemists are rethinking the way atoms stick together.
