Unexpected Elements

• A science heist

  The daylight robbery of precious crown jewels from the Louvre museum in Paris has us stealing your attention to inspect heists and crime scenes in science.We explore how stealthy spiders use tricks and deceit to rob precious prey from one another, and we look at how seagulls and other birds have the advantage when it comes to stealing food from humans. We also learn how our immunological security systems try to prevent bacteria from doing an iron-heist from our cells and blood.But what about figuring out whodunnit? Forensic ecologist and palynologist Professor Patricia Wiltshire shares how pollen can be instrumental when solving crimes and how thorough, detailed forensic work can help uncover the truth when unravelling mysteries.We also hear about the tensions between elephants and humans in Kenya, why we prefer the taste of certain foods, and how the code to a famous puzzle-filled sculpture might have finally been cracked. All that, plus many more Unexpected Elements.Presenter: Marnie Chesterton, with Phillys Mwatee and Kai Kupferschmidt Producers: Imaan Moin, with Lucy Davies, Eliane Glaser and Robbie Wojciechowski

• How does biometric data work?

  Europe has a new entry/exit system based on biometric data. But what exactly is the science behind biometric data, how can we ensure it’s used responsibly, and can it be cracked?We also look at how some animals use dung as biometric data with Dr. Adrian Shrader, how your walk can be used to ID you from Professor Mark Nixon, and why gold has its own special measurement. All that plus many more Unexpected Elements.Presenter: Marnie Chesterton Producers: Margaret Sessa-Hawkins with Lucy Davies and Robbie Wojciechowski

• Why are gold prices so high?

  Record high gold prices have us looking at the science of inflation, why gold is leaking from volcanoes, and entomologist Katy Prudic explains why shiny gold can be a good color for camouflage.Plus the dark science going on in a gold mine, whether we can move at the speed of light, and the debate around golden rice. All that, plus more unexpected elements.Presenter: Marnie Chesterton Producers: Alice Lipscombe-Southwell, with Margaret Sessa-Hawkins, Robbie Wojciechowski and Lucy Davies.

• The strongest stuff in the Universe

  Egyptian strongman Ashraf Mahrous recently pulled two ships totalling 1,150 tonnes with his teeth, setting his sights on the Guinness World Record. Inspired by this story, this week we’re tackling the science of all things strong. First, we find out about new research that could keep our muscles strong as we age. Next up, we discover why graphene is so strong and how it could help improve data storage. We're then joined down the line by Dr Matt Caplan, an astrophysicist from Illinois State University, who tells us about his search for a weird substance called ‘nuclear pasta’. And no, you won’t find it in your local Italian restaurant. Plus, find out how robo-exoskeletons can help you climb hills and why Ernest Shackleton’s Endurance was weaker than expected. All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Kai Kupferschmidt and Andrada Fiscutean Producers: Alice Lipscombe-Southwell, with Robbie Wojciechowski and Lucy Davies

• Science inspired by Taylor Swift

  The launch of Taylor Swift’s much-anticipated 12th studio album, The Life of a Showgirl, has inspired this week’s episode of Unexpected Elements.First up, we hear how a Brazilian songbird courts its mate as part of a boyband. We then find out about the microbes that dance to survive in their extreme habitat. Next up, Professor Troy Magney, a forest ecophysiologist at the University of Montana, tells us about his TSWIFT machine and how it can assess the health of the planet’s forests. Also in the programme, we find out why migratory birds trick weather data, how fish sing, and how hackers used SWIFT bank payments to nearly pull off a billion-dollar heist.All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Camilla Mota and Godfred Boafo Producers: Imaan Moin and Alice Lipscombe-Southwell, with Robbie Wojciechowski and Lucy Davies
