The news you know, the science you don’t. Unexpected Elements looks beyond everyday narratives to discover a goldmine of scientific stories and connections from around the globe. From Afronauts, to why we argue, to a deep dive on animal lifespans: see the world in a new way.

The gift of science

This Boxing Day and holiday season, our present to you is the science of gifts. First, we investigate the health benefits of donating blood, and find out about the predator sharing a feast of food in the Arctic. We’re then joined in the studio by physicist Dr Krishma Singal from Rice University, who unravels the soft-matter physics and brilliant engineering potential of knitting. Next, we discuss the reputation of piranhas, enquire about the uniqueness of our sneezes, and break down how salting roads makes them safer in the winter. All that, plus many more Unexpected Elements. Presenter: Alex Lathbridge, with Camilla Mota and Meral Jamal Producer: Imaan Moin

Why are we sad when television series end?

The end of Australian soap opera Neighbours has us wondering why a television series ending makes us sad. Also, what does science say about how to engage with screens while still protecting your vision? Also on the show, visual ecologist Daniel Hanley has created a camera to help us visualize the world animals see, and why are there green birds, green insects, but no green mammals? All that plus more Unexpected Elements. Presenter: Marnie Chesterton Producers: Margaret Sessa-Hawkins, Alice Lipscombe-Southwell, and Ella Hubber

Chicken, with a side order of science

Over the Christmas season, it is estimated that some 3.6 million families in Japan will tuck into KFC over Christmas (other fried chicken is available), which inspired the Unexpected Elements team to chew over all things chicken! First, we discover that chicken may never have become domesticated if it wasn’t for rice farming. We also ponder whether the chicken or the egg came first. Next, we find out that humans are surprisingly smart at translating chicken chatter. We are by Dr Jingmai O’Connor, associate curator of fossil reptiles at the Field Museum of Natural History, who reveals more about the links between dinosaurs and birds. Plus, how Brazil became a poultry superpower, and what happens to chickens in tornadoes. Presenter: Marnie Chesterton, with Camilla Mota and Godfred Boafo Producers: Alice Lipscombe-Southwell, with Sophie Ormiston, Ella Hubber and Robbie Wojciechowski

Some bear-y interesting space science

A teddy bear launched into the upper atmosphere as part of a school science project has gone missing! Inspired by this story, the Unexpected Elements team look into how bears could help improve astronauts’ health on long-term space flights. Next, how has a US Air Force site delivered an unexpected conservation win for an endangered species? We’re then joined by Justin Gregg, a professor of animal behaviour and cognition. He reveals why we anthropomorphise cuddly toys – such as teddy bears – and why this isn’t necessarily a bad thing. We meet Alan Turing’s teddy bear, before finding out why it’s good to get lost. All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Andrada Fiscutean and Chhavi Sachdev Producers: Margaret Sessa-Hawkins, with Alice Lipscombe-Southwell, Alice McKee and Robbie Wojciechowski

The unexpected science behind Klimt's artwork

The Portrait of Elisabeth Lederer by Gustav Klimt has recently sold for $236m, making it the second-most expensive artwork ever sold at auction. Inspired by this headline, the Unexpected Elements team delve into the story of how microbiology may have influenced Klimt’s work. Speaking of microbiology, we find out that bacteria could help restore frescoes to their former glory. We also get on the line with Dr Siyakha Mguni, an archaeologist and senior lecturer at the University of Cape Town, who tells us about ancient artworks far older than anything Klimt ever painted. Plus, the world’s biggest spider’s web, and why mosquitoes are impressive 3D printers. All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Andrada Fiscutean and Edd Gent Producers: Alice Lipscombe-Southwell, with Margaret Sessa Hawkins, Alice McKee, Lucy Davies and Robbie Wojciechowski

Some Beautiful Science

The Miss Universe pageant final has us considering the science of beauty. How much of our perception of beauty is genetic, and how much is down to personal experiences? We also look at the science behind competitions and the audience effect. Why do we sometimes perform better when we’re watched? Also on the show, Oxford professor Marcus du Sautoy explains why maths can be beautiful, and former Miss Universe Ireland and NASA datanaut Fig O’Reilly talks about balancing pageants and a career in science outreach. Plus, the science behind death metal singing, why civet coffee tastes so good, and how ugly plants inflame allergies, on this week’s Unexpected Elements. Presenter: Caroline Steel, with Katie Silver and Sandy Ong Producers: Margaret Sessa-Hawkins with Alice Lipscombe-Southwell, Lucy Davies, Robbie Wojciechowski and Alice McKee

A keg of beer-based science

A 150-year-old bottle of Arctic Ale is being uncapped, which got the team talking about all things related to yeast, beer, and opening things. First, we hear about a rare condition where the body brews its own alcohol. Next up, we find out that small amounts of alcohol make male fruit flies more attractive. We’re then joined in the studio by food historian Pen Vogler, who helps us travel back in time to explore beer’s origins. Next, we discover how air pollution is affecting our brains, and delve into some surprising ways that yeast could help the climate. All that, plus many more Unexpected Elements. Presenter: Marnie Chesterton, with Chhavi Sachdev and Candice Bailey Producers: Alice Lipscombe-Southwell, with Lucy Davies and Robbie Wojciechowski

A storm of science

As rescue and relief efforts in the Caribbean are ongoing after Hurricane Melissa, Unexpected Elements looks at the science of storms. We explore how AI might help us better predict the weather patterns, and whether it could act as an early warning signal to help us prepare for natural disasters, and we look at what a sinkhole off the Coast of Belize has helped reveal about 6000 years of storm history in the Caribbean. Giles Harrison, Professor of Atmospheric Physics at Reading University helps explain the unexpected link between bees and storm clouds. We also investigate whether storms with female names are more deadly, your letters have us contemplating banana varieties, and whether wind turbines could ever have an effect on the breeze. Presenter: Alex Lathbridge, with Andrada Fiscutean and Leonie Joubert Producers: Margaret Sessa-Hawkins with Eliane Glaser, Minnie Harrop, and Lucy Davies
