• Silent science

  Sparked by a silent album released by 1,000 musicians in protest of the UK government’s planned changes to copyright law, Unexpected Elements hits the pause button... Is there any science to silence?Fear not, this week’s show is packed full of chatter! You might think there’s only one type of silence, but supposedly exists in political science too. In fact, there are seven distinct types.If you're a techy you probably have a pair of noise cancelling headphones. But have you ever wondered how they work? We’ll take them apart to figure out how they work. Plus, dive into the fascinating world of gene silencing, definitely one of the coolest areas of genetics. Learn how this cutting-edge technology could help protect our crops from pests in the future.Later, Caroline is joined by her two wonderful panellists to contemplate and reflect on silence, when might it be harmful? And does true silence even exist?All that and many more Unexpected Elements.Presenters: Caroline Steel, Candice Bailey and Kai KupferschmidtProducers: Harrison Lewis, with William Hornbrook, Debbie Kilbride and Noa Dowling
