For International Talk Like a Pirate Day on 19th September, we dig up a treasure chest full of pirate-inspired science.First up, we peer down our microscopes at a bacterium that takes its inspiration from a pirate warship. Next, we turn our attention to scurvy, the disease that plagued mariners and is now making a comeback in the modern age. We then get on the line with marine archaeologist Dr Sean Kingsley, who is about to set sail on a mission to survey the unexplored wrecks of Nassau. Plus, we delve into the tricky topic of modern-day piracy and copyright, before testing our pirate knowledge in a swashbuckling quiz.All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Kai Kupferschmidt and Sandy Ong
Producers: Alice Lipscombe-Southwell and Margaret Sessa Hawkins, with Robbie Wojciechowski and Imaan Moin
