  • Kenya believe it?
    This week the Unexpected Elements team left our windowless BBC studio and paid a visit to the CGIAR conference in Nairobi, Kenya. In this episode, we find out about the Kenyan invention that’s pulling clean, safe water from thin air, before discovering what makes Kenyan coffee taste so great. Next, we hear about the problems with burning charcoal and the ways in which briquettes could offer a cleaner, more sustainable solution. Plus, we’re joined by Joyce Maru, the regional director for Africa at the International Potato Centre. She reveals the science behind the orange-flesh sweet potato and explains how it could improve livelihoods and boost health across Africa. We then hear about the story of the two Kenyan inventors who have created a Swahili-speaking robot. Finally, our panellists go against the clock in our Kenyan Science Showdown. All that, plus many more Unexpected Elements.     Presenter: Alex Lathbridge, with Christine Yohannes and Phillys Mwatee Producers: Alice Lipscombe-Southwell, with Sophie Ormiston and Harrison Lewis Studio engineers: Andrew Garratt and Gayl Gordon

  • An eggciting episode
    This week is the Christian celebration of Easter, which sent the Unexpected Elements team scrambling for egg-related stories. First up, we find out about the rise of a vegan egg substitute. Next, we discover how to cook the perfect boiled egg, according to science. We then turn our attention to climate change, and find out how it is affecting the breeding patterns and nesting behaviour of sea turtles. Plus, we are joined by Dr Luis Welbanks, who tells us about a nearby exoplanet that reeks of rotten eggs. Finally, we delve into the science behind IVF. All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Chhavi Sachdev and Sandy Ong Producer: Alice Lipscombe-Southwell, with Debbie Kilbride, Robbie Wojciechowski and William Hornbrook

  • Navigating northward
    The Aurora Borealis – also known as the Northern Lights – won’t be at their peak activity much longer, and the Unexpected Elements team dreams of going north to see them. And that has got us looking at the science of navigating our way north! We hear about how humans have been using the sky to navigate for millennia, and we learn about how relying on GPS may be impacting our memory ability. And while humans use maps to get around, how do animals know where to go on their long migrations? To find the answer, we speak to Dr Kayla Goforth at Texas A&M University who studies exactly how sea turtles and monarch butterflies innately know how to navigate the world around them. We also learn why polar bears keep themselves ice-free, and we hear old records of the first men to reach the North Pole. All that, plus many more Unexpected Elements. Presenter: Caroline Steel, with Andrada Fiscutean and Phillys Mwatee Producer: Imaan Moin, with Alice Lipscombe-Southwell, Noa Dowling and William Hornbrook

  • Oh, Rats!
    On World Rat Day, we’re getting ratty! We look at the biology behind the eternal struggle between rats and rat poison, and we hear about rat-on-rat warfare and other forms of pest control. We don’t play games when it comes to rats, but we know someone who does. Dr Michael Brecht from the Humboldt University of Berlin tells us how he played hide-and-seek with lab rats and what that tells us about the behaviour of play. On the topic of ‘rat’ behaviour, we are joined by Dr Zach Berry from the University of Southern California to talk about the psychology behind ratting people out in the workplace, testing the loyalty and morals of the Unexpected Elements team. And speaking of rats in the workplace… we hear a first-hand report on whether African giant pouched rats might just be better staff members than humans when it comes to detecting tuberculosis at APOPO labs. All that, plus many more Unexpected Elements. Presenter: Anand Jagatia, with Tristan Ahtone and Christine Yohannes Producer: Imaan Moin, with Debbie Kilbride, Alice Lipscombe-Southwell, Noa Dowling, Harrison Lewis and Sophie Ormiston. Studio Manager: Cath McGhee

  • Don’t be a fool!
    April 1st is notorious across the globe. Renowned for being a day of practical jokes. And it’s no different here on the BBC World Service. Mischievous elephants, the secret to fool's gold and one of the biggest scientific hoaxes in scientific history. From the Magic Circle to the Magic Lab, the psychology underpinning why we humans are so delightfully easy to trick with Professor Gustav Kuhn. And a question sent in from one of you: if two people eat the same thing for breakfast, does the same thing come out the other end of both of them? Prepare for a prank or two on Unexpected Elements. Or as they say in Finland, ‘Aprillia, syö silliä, juo kuravettä päälle’, which translates to ‘April trick, eat herring, drink muddy water afterwards!’ Presenters: Caroline Steel with Camilla Mota and Phillys Mwatee Producers: Harrison Lewis, Alice Lipscombe-Southwell, William Hornbrook and Imaan Moin
