Unexpected Elements

• Some really cool science

  This week, the Florida Panthers beat the Edmonton Oilers at ice hockey’s Stanley Cup championship, which sent us skating into ice-related science.First up, we hear about an ancient ice skate that’s been unearthed in Prerov, Czech Republic, which sends us pondering about the physics of ice-skating. We then discover why licking a flagpole on a chilly day is a bad idea, before delving into the science of cryopreservation. Next up, we speak to Dr Mark Drinkwater of the European Space Agency, who reveals how satellites can help us monitor and better understand our planet’s melting ice sheets. Plus, what do you do if you want to play ice hockey but you live near the equator? All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Chhavi Sachdev and Sandy Ong Producer: Alice Lipscombe-Southwell, with Margaret Sessa Hawkins and Minnie Harrop

• Defuse and diffuse

  World War II bombs were defused in Cologne, Germany, which has inspired us to explore the science of diffusion and defusing!First, we hear how new, artificially intelligent video generators are modelled on diffusion. We also hear about the health impacts of home aroma diffusers and candles. We’re joined by conflict-mediator Gabrielle Rifkind of the Oxford Process, to discuss the psychological stakes behind defusing conflict in wars and at home.We also taste-test the difference between raw and cooked broccoli, learn about in-insect synthesis, and explore an anechoic chamber. All that, plus many more Unexpected Elements. Presenter: Caroline Steel, with Tristan Ahtone and Edd Gent Producer: Imaan Moin, with Alice Lipscombe-Southwell, Minnie Harrop and Debbie Kilbride

• Gaming-inspired science

  This week, get ready for a whole loot box of gaming-related stories!First up, we find out about a video game that could give people the power to battle misinformation. We also hear how scientists are putting harbour seals in front of a computer monitor to decipher how they navigate under the water. And Dr Brett Kagan from Cortical Labs joins us down the line to tell us why he taught a clump of brain cells to play the 1970s arcade game Pong. Along the way, we discover what happens when artificial intelligence tries to explain idioms, we learn about a tiny frog named after Bilbo Baggins and try to establish whether or not video games benefit your brain. All that, plus many more Unexpected Elements.     Presenter: Marnie Chesterton, with Kai Kupferschmidt and Leonie Joubert Producer: Alice Lipscombe-Southwell, with Margaret Sessa Hawkins, Imaan Moin and Minnie Harrop

• Mission unexpectedly possible

  With the new Mission Impossible film playing in cinemas, the Unexpected Elements team is channelling Tom Cruise’s energy to see if scientists can push the boundaries of what is considered ‘impossible.’ First up, we fuse medieval alchemy with particle physics and explore a method to turn lead into gold. We then look at the latest research that uses artificial intelligence to help us humans communicate with animals. We put the spotlight on a favourite trope of science-fiction films – time travel! String theorist Brian Greene of Columbia University explains how going to the past, or back to the future, may or may not be hypothetically possible. We also ponder ancient auroras, whether ants can plan a Hollywood-style heist, and what it takes to understand our consciousness.    Presenter: Marnie Chesterton, with Affelia Wibisono and Andrada Fiscutean Producer: Imaan Moin, with Alice Lipscombe-Southwell Studio engineer: Mike Mallen

• Story time

  Much ado was made about a cancelled auction of an ultra-rare set of Shakespeare’s folios, which could have fetched millions of dollars. This headline – along with Shakespeare being one of the world’s most well-known playwrights – inspired the Unexpected Elements team to delve into the science of stories. First up, we find out why your brain loves a tale. We then discover that some people can’t see images in their mind when they read, and reveal the impact this could have.Shakespeare’s folios are almost 400 years old, but how have they survived that long? We get on the line with Kathryn Kenney, a book and paper conservator, to find out how she keeps precious books safe. We also find out about a disappearing island, whether climate change needs a new narrative and if you could eat books to survive. All that, plus many more Unexpected Elements.     Presenter: Marnie Chesterton, with Camilla Mota and Tristan Ahtone Producer: Margaret Sessa Hawkins, with Alice Lipscombe-Southwell, Imaan Moin and Minnie Harrop Studio Manager: Rhys Morris
