The Hindu festival of Kumbh Mela is currently underway in India. As part of the event, millions of pilgrims will take a cleansing dip in the confluence of the Ganges, Yamuna and the mythical Saraswati. Inspired by this headline, we splash into a whole bathtub of stories about the science of cleaning. We find out why it’s so important to prevent contamination of other planets and moons, and how space scientists keep things clean. Next up, we discover how our brains clear out harmful toxins while we snooze. And is there any truth in the saying, ‘tidy house, tidy mind’? Finally, Marnie ponders whether it’s possible to be too clean, or if being a bit grubby is okay.

After the comic malfunctions of a self-driving car, which drove its passenger/prisoner in endless circles, Unexpected Elements rounds its attention on the humble circle. Explore how one man calculated the circumference of the Earth 2,000 years before GPS was invented, then be spellbound by the Magic Circle and the mysterious woman who broke into it. And as we hit the five-year anniversary of the Covid pandemic, we take a look at the cycle of infection and mutation, before asking, 'why don’t we have one antiviral pill that kills them all?' We’re joined by evolutionary psychologist Professor Robin Dunbar, who calculated Dunbar’s number; that is, the maximum number of folks you can hold onto in your circle of friends... five? 500? 5,000? Robin reveals how many REAL friends science says you can have.

Team Unexpected have been digging into their mind palaces to pull on the scientific research that has stuck with them most over the past year. We hear from Professor John Parnell, geologist at the University of Aberdeen, about the role of plankton in forming ancient mountains. How ocean bubbles play a role in climate regulation with bubble physicist Dr Helen Czerski from University College London. Would you know how to measure the size of a bubble? We also participate in some memory sports with Jonas von Essen who is a two-time world memory champion. He helps us construct a mind palace in order to memorise really long strings of digits. Plus we look into the backstory of the human buttocks with science journalist and reporter Heather Radke. She answers the question ‘why do we humans have such large behinds?’ And we hear from Professor Andre Isaacs at the College of the Holy Cross who has filled his chemistry lab with music and dance in order to change perceptions about who can be a scientist.

December is a time of celebration, family feuds, and now scientific rivalries. It's also one of the most wasteful months of the year, with festivities in full swing across the globe. No wonder the world is overflowing with rubbish—both literal and metaphorical! Unexpected Elements dives headfirst into the scientific bin to wallow in waste. Could worms be the unexpected heroes of our plastic pollution crisis? How much garbage have we jettisoned into space? And why is part of our very own genome called "junk DNA"? But it’s not all rubbish, we’re also talking trash. While celebrations can bring people together, spending too much time with loved ones can lead to tense moments. Rafi Kohan shares expert tips on how to outsmart your opponent during a heated board game debate. And don’t think trash talk is limited to sports fields. The world of science has its share of drama, too. We’ll explore some of history’s most scandalous squabbles with scientists behaving badly. Come waste an hour with us on Unexpected Elements!

This week, a banana sold at auction for $6.2 million dollars. Well, not quite… it’s actually a piece of conceptual art and it’s WAY more than just a banana. There’s also some duct tape. In response to this most bananas of auctions, the Unexpected Elements team are going bananas for bananas! We investigate the science of slipping on a banana-skin. Is it just ‘cartoon physics’ or are they actually a slip-hazard? And did you know your breakfast banana might be… radioactive? Also, can Romanian ethical hackers succeed where the police have failed? We look at the computer sleuths tackling real life missing persons cases. We find the answer to why toads have evolved such dangerous skins, and yet more bananas, as we look at the pros and cons of the Ethiopian False Banana. Why hasn’t this hardy plant conquered the world?

This week we’re looking at a political agreement that will hand back sovereignty of the Chagos Islands to Mauritius. In the 1970s, the UK removed the entire Chagossian population to make way for a US military base. The islanders have been fighting for their right to return ever since. If deal can be agreed, the islanders are hoping they will have the chance to go home. And this got us thinking about all things home-related. First up, we discover the intriguing reasons why you can’t smell your own home, then we take a closer look at our homes and all the creatures that live there, before finding out about the ‘home scars’ created by limpets. Next we hear from Dr Nadescha Zwerschke, a scientist who spent time on Rothera research station in Antarctica. She reveals how she made this isolated outpost feel like home. Also, we reveal that global talks to agree a reduction in plastics have collapsed, which could have an impact on all our homes from a pollution perspective. And finally – a type of pasta that would be no good for your homecooked recipes.

Headlines that Canadian uranium deposits could make it a nuclear superpower has the Unexpected Elements team musing on all manner of superpowers. Tardigrades are an obvious candidate – boil them, freeze them, irradiate them in space, these adorable creatures are almost indestructible. We also meet Dr Deep Sea, Joseph Dituri, from the University of South Florida, who lived under water for 100 days and swears by it as a boost for our health. As the leader of the free world goes on an Amazon jungle tour, we talk tiny frogs, giant frogs and radiation tolerant frogs. We also hear how cancer survivors may have a secret superpower and how we’ve co-opted plants superpowers for medicines.

Russia has fined Google more than two undecillion rubles, which is more than 20 decillion dollars. How much you ask? 20 decillions is a 20 with 33 zeros behind it, more money than there is in the entire world! This unpayable fine inspired us to look at extremely large numbers, from the amount of cells in our body, to infinity hotels and beyond. Plus, two-time world memory champion Jonas von Essen teaches us how to memorise these supermassive numbers. Also, we unpick a dubious influential biodiversity statistic that has no basis whatsoever, and we look at the scientific tools of ghost hunting. Plus, to round it off, presenter Marnie looks at a sport with more possible moves than there are atoms in the Universe. Can you guess what it is?

On this weekend ahead of the US election, we clock the importance of so-called swing states – and swing into action looking into not politics, but the science of swings. We examine how a pendulum swung by French physicist Foucault demonstrated that the earth is spinning, and hear about how the gibbon became the king of swingers – and what current-day elite climbers can learn from them. We also hear from educator Francis Mavhunga at the University of Eswatini who has regularly used swings in his physics classes, and now shows a new generation of teachers how to integrate children’s lived experiences into the classroom. Plus, how science has revealed new secrets about the ancient silk road, and what your brain can see when your eyes can’t. And, just to swing back to the beginning, presenter Marnie Chesterton digs into the archives to find out if science and tech can provide a foolproof voting system, and how astronauts vote.

White blobs have been appearing on the beaches in Newfoundland, Canada. They’re kind of doughy-looking, and smell of vegetable oil. As yet, officials are not sure what they could be. Of course, this got the Unexpected Elements team intrigued, so we decided to dedicate the programme to the weird world of blobs, slime and bizarre things that wash up onshore. We hear about the fabulous hagfish, which produces copious amounts of snot-like slime to defend itself from predators. But what makes slime so slippery in the first place? And why is ketchup so hard to get out of a bottle? And what makes quicksand so difficult to escape from? It’s all down to fluid dynamics. Professor Daniel Bonn, from the University of Amsterdam, explains the physics behind all these sticky situations. Also this week, we find out more about a shipment of bath toys that tumbled overboard, and how they have helped scientists to decipher ocean currents. Plus, we discover more about the restoration of mangrove forests, how flowers can cause weird dreams, the size of the biggest black forest gateau and a species of plankton and how it floats.

Spoiler alert! At the end of the fourth season of Emily in Paris, the protagonist sets off to go to Rome. In response, the French President Emmanuel Macron has promised that “we will fight hard” to keep Emily in Paris in France. Why does he care so much? A recent study suggests that 38 per cent of all visitors to Paris name the show as one of the reasons for visiting. Inspired by this factoid, we started thinking about the ways in which TV can influence us. We examine how Star Trek inspired mobile phones – and the outfit of one of our panelists. Plus, we find out more about the impact Dana Scully from The X Files had on a generation of girls. And what does psychology say about fandom? But how can science influence the films? We speak to Dr Adam Rutherford, a geneticist, broadcaster, and, importantly, scientific advisor for movies. What does that last role involve? Which films get the science right? And is scientific accuracy important for a Hollywood blockbuster? Also in the programme, we hear about the mysterious recent earthquakes in Ethiopia, and Unexpected Elements listeners with visual impairments get in touch to share the secrets of what they can see inside their heads. And finally, we take a look at the surprising connection between cricket and statistics.

A replica of the final prize – a golden owl – was dug up in France, leaving fellow treasure hunters both disappointed and relieved. Inspired by this pursuit, the Unexpected Elements team unearth some of science’s hidden gems. From the potential resurrection of ancient healing tree balm to the world’s rarest stone, and even how cats could help solve crimes. The team are also joined by astrobiologist Nathalie Cabrol to speak about the potential treasures hiding on another moon in our solar system. Along the way, our panel have their own clues to crack as they take on a mini hunt of their own to find the location of a scientific golden nugget. Plus, we solve the mystery of a moth which ended up 4000 miles from home, hear what our brains see when we can’t and talk about returning treasures to where they came from.

Did you know the iconic yellow smiley face was first designed in 1963? However, its creator, Harvey Ball, soon worried that the symbol had become over-commercialised. To counter this, he introduced World Smile Day in 1999, celebrated on the first Friday of October, as a way to encourage acts of kindness and spread smiles. In the spirit of making you smile, the Unexpected Elements team has gathered science stories that bring them joy—each with a twist, of course. Children across cultures have invented secret languages to confuse their parents—and there's science behind it. The human face can produce 19 different types of smiles. And let’s not forget the Brazilian scientist who not only pioneered species classification but also became a key figure in the country's suffragette movement. Meanwhile, Marnie Chesterton introduces us to the ever-cheerful Professor Andrea Sella from University College London, whose humour never fails to brighten her day. Together, they explore the role of humour in science and its importance in engaging both audiences and students. Plus, we’ll dive into the science of vocal fingerprints, meet a man who physically couldn’t smile, and hear about a global update to cyber security regulations that just might make you grin. Happy Friday! Presenters: Marnie Chesterton with Andrada Fiscutean and Camilla Mota Producers: Harrison Lewis with Jonathan Blackwell, Elizabeth Barsotti, and Anna Charalambou.

This week, Apple releases the new iPhone 16. It's new, it's shiny, and tech-nerds will be queueing round the block for a chance to snap it up. But why? We look at the science behind why we get so dazzled with new and shiny things. We hear about the psychology behind our magpie tendencies, and find out it might all be connected to one of our deepest evolutionary drives: for clean, fresh, sparkling water. And we find out what the shiniest thing in the natural world is. An extraordinary blue berry with some mesmerising visual qualities. We find out about diamonds made from your dead pets. And, we dissect the science behind the first flush of love. Why do we get so obsessed with a new partner? And why doesn't the feeling last?

Ngā Wai Hono i te Pō ascends the Māori throne as the new Kuini (Queen), much to the joy of her people, heralding a new age of prominence for the Kiingitanga movement. We ask whether the new queen may have a biological advantage making her a better fit for leadership, whilst searching for examples of matriarchy in the animal kingdom and analogous human societies. As is customary, Ngā Wai Hono i te Pō was crowned on the same day as her father’s funeral, thrust into a leadership role during a time of profound grief. We hear from Prof Lucy Selman, expert in palliative and end-of-life care from the University of Bristol, and founder of the Good Grief Festival. She speaks about the physical and emotional manifestations of grief and how it can be processed and overcome, even in the face of immense responsibility. We remember the legendary voice of the late James Earl Jones, who played the intergalactic monarch, Darth Vader, as Marnie unpicks the science of stuttering. Unravel a massive jigsaw puzzle, uncover a hidden secret behind Queen’s hit song Don’t Stop Me Now, and delve into the fascinating realm of neuroscience and much more on Unexpected Elements.

Here on Unexpected Elements, we've been glued to the drama of the Paralympic games in Paris. But it's not just the thrill of the competition that's got us hooked, we've also become obsessed with some of the high-octane training regimes undertaken by the athletes. Take American 'Armless Archer' Matt Stutzman, who shoots arrows through the windows of his own house and car to recreate the high pressure of the Olympic stadium. He's chasing a thrill, and so are we! We hear about the research on one extraordinary woman who had a medical condition which caused her to have no fear. And we follow the fate of an extraordinary marine creature, who detaches his own arm in his quest for a mate. We hear about why humans love to be scared - as long as it's all in good fun. And we hear about the space debris falling to earth, and the thrilling quest of a plane full of scientists who want to watch it fall. That and loads more unexpected elements in this week's show.

Following anti-tourism protests across popular Spanish cities and towns, we are looking for the world's most unwelcome visitor. Our panellists (and producers) are pitching their terrible tourists to see who really is the worst of them all. Some of our contenders include... The wild boars who's unanticipated vacay to Rome has gone on for so long and caused so much carnage that researchers are putting them on birth control. The microbes potentially hitching a ride to the moon via space probes and astronauts' poo The multi-destination parasite who wreaks havoc as it interrails through snails (castrating them on the way), frogs (making them spout multiple limbs) and birds. But there are some instances when tourists can be a good thing - and this is especially the case in the human body when we want to grow a baby. How is in that we are able to protect what should be an 'unwelcome visitor' from a hyperalert, hostile immune system? Our expert Edward Chuong explains. Plus, we uncover the DNA origins of the world's most popular coffee bean, hear the freeloading activities of the male angular fish, and read out a selection of your wonderful emails.

The US astronauts Butch Wilmore and Suni Williams are currently stranded on the ISS. They arrived on the Boeing Starliner, which was meant to bring them home after eight days. Unfortunately, it has run into tech issues, meaning that the astronauts may be stuck up there for up to eight months. We started to ponder, what could an extended period of being stuck in space do to your body? Next we look to the world of psychedelics research, which has currently got itself a little bit stuck. We also find out more about the Haraldskær Woman, discovered preserved in a Danish bog in the 1800s. Mads Ravn, head of archaeology, research and collections at the Vejle Museums in Denmark, reveals the stories behind the bog bodies and explains how they ended up stuck in the mud. And staying with the theme of stickiness, we find out what Neanderthals used as glue. That, plus many more Unexpected Elements.

The Olympics is all about flying the flag for your home country, shoulder to shoulder with your team-mates. But what if you have no team-mates? At this year’s Olympic games, four countries had just one competitor. Like Sean Gill from Belize, Somalian runner Ali Idow Hassan, or Romano Püntener, a mountain-biker representing Liechtenstein. This got us thinking about the only one. The panel discuss what it must be like to be an ‘Endling’ – the last remaining animal of an otherwise extinct species, and wonder if there might be ways to bring them back. We delve into the intriguing psychology behind the urge to collect things, why collectors are so entranced by rare items, and how the psychological pull of ‘exclusivity’ and ‘limited editions’ can make us vulnerable to marketing scams. And what about a baby, born of only one parent? A ‘virgin birth’ – a miracle perhaps? Not so, as we discover that females giving birth without any help from males is surprisingly common. It is called Parthenogenesis, and although humans cannot do it, a dizzying array of animals can. Alexis Sperling from the University of Cambridge explains the science.
