This week on the podcast, Robert Carlyle drops by to talk about his new drama series COBRA, which despite Robert’s suspicions is not about a snake. In the Maths of Life, Dr Hannah Fry explains how gossip networks work, and the science behind fixing London’s wobbly Millennium Bridge. Rhianna Dhillon gives us her viewing picks in This Week’s Watchlist, featuring the BBC’s new three-part series Dracula, Jojo Rabbit at the cinema, and Netflix’s true crime documentary Don’t F With Cats. Plus there’s more brilliant House Music – the everyday objects that just cannot stop playing pop hits.
