Standing on the shoulders of giants
2/21/2025
Monty the giant schnauzer won best in show at the Westminster Kennel Club Dog Show. And rather than thinking of all things canine, this week the Unexpected Elements team turn their attention to all things giant.
First, we find out how a giant virus could help keep our planet cool.
Next up, we discover the origins of enormous Greek characters, such as the Titans and the Cyclops. We then find out how giant clams put solar panels to shame.
Plus, we’re joined by Professor Shinobu Ishigaki, director of the Museum of Dinosaur Research at the Okayama University of Science. He tells us about the ginormous footprints he found in the Gobi Desert, and what they could teach us about herbivorous dinosaurs.
That, plus many more Unexpected Elements.
Presenters: Caroline Steel, with Chhavi Sachdev and Camilla Mota. Producers: William Hornbrook, with Alice Lipscombe-Southwell, Debbie Kilbride, Imaan Moin and Noa Dowling.

Let’s talk about love
2/14/2025
Valentine’s Day is here. It’s that one day of the year where you can be unashamedly romantic and splash out on posh dinners, flowers and chocolates for your beloved.
Yes, all that is wonderful, but the Unexpected Elements team wanted to dig into the science of love.
First, we find out about a monogamous rodent that has a special way of forming lifelong bonds with its partner.
Next up, we discover how to apply maths to your love life, before delving into the technology behind AI chatbots, and finding out if a new dating app can help shine a light on the science of compatibility.
Plus, we’re joined by Bianca Acevedo, a research scientist at the University of California, Santa Barbara, who studies the neuroscience of love. She reveals what’s going on in our brains when we’re infatuated with someone and what purpose love serves.
That, plus many more Unexpected Elements.
Presenters: Marnie Chesterton, with Tristan Ahtone and Edd Gent. Producers: Alice Lipscombe-Southwell, with William Hornbrook, Debbie Kilbride, Imaan Moin and Noa Dowling.

All by myself
2/7/2025
French president Emmanuel Macron recently announced that Leonardo da Vinci’s famous Mona Lisa painting will be moved to her very own room at the Louvre, as part of a plan to renovate the iconic museum.
And that got us thinking. Once the crowds have gone home every night, the Mona Lisa will be all by herself, with no other paintings to smile at enigmatically across the room.
So this week, we are talking all things isolation. We start things off by finding out about a key cognitive skill that may have been impacted by COVID-19 lockdowns.
Next, we discover more about the history of loneliness and the impact it can have on your health, before discussing what evolutionary roads isolated island species will go down.
Plus, we’re joined by Professor Jonathan Harrington from the University of Munich. He reveals how our accents can be affected by isolation. That, plus many more Unexpected Elements.
Presenters: Marnie Chesterton, with Christine Yohannes and Affelia Wibisono. Producers: Alice Lipscombe-Southwell, with Dan Welsh, William Hornbrook and Imaan Moin.

Snake science
1/31/2025
Celebrations for the Lunar New Year kicked off on 29th January, and this year is the Year of the Snake.
We start things off by discussing the purpose of some mysterious serpent markings on the banks of the Orinoco River.
Next, we find out about the origins of snake oil, before digging into the psychology of why we trust snake-like people.
Plus, herpetologist Dr Mark O’Shea tells us all about his work identifying snakes, and what happened when he got bitten.
That, plus many more Unexpected Elements.
Presenters: Marnie Chesterton, with Chhavi Sachdev and Christine Yohannes. Producers: Dan Welsh, with Alice Lipscombe-Southwell, William Hornbrook and Imaan Moin.

Keep it clean
1/24/2025
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. Presenters: Marnie Chesterton, with Affelia Wibisono and Andrada Fiscutean Producers: Alice Lipscombe-Southwell, with Dan Welsh, William Hornbrook and Imaan Moin

Scientist spotlight
1/10/2025
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. That, plus many more Unexpected Elements. Presenter: Marnie Chesterton Producer: Jonathan Blackwell and Harrison Lewis with Imaan Moin and Alice Lipscombe-Southwell

(Re)New Year
1/3/2025
Happy New Year! This week, the Unexpected Elements team is reflecting on 2024 and looking forward to 2025 for renewed chances to spot the northern lights while they're at their peak visibility in this current solar cycle, and we recap on cellular regeneration advancements and regulations in embryonic stem cell models.
We chat to Professor Rene Oudmaijer from the Royal Observatory of Belgium who explains that stars also renew themselves... and this process is key to our lovely planet (and ourselves) existing!
We also learn all about the potential of bogs and wetlands in the fight against climate change from Professor Christian Dunn of Bangor University.
With another amazing year behind us, we reminisce about our favourite stories and listener correspondences in 2024.
And finally, we’re wowed by the regenerative ‘superpowers’ of the magnificent axolotl who has the cellular capabilities to re-grow limbs!
That, plus many more Unexpected Elements.

Festive Trash Talk
12/27/2024
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!

The science of Santa
12/20/2024
As news breaks that archaeologists have found the tomb of St Nick in Turkey, we check in on the North Pole Father Christmas, and fact-check his present giving schedule with advanced level physics and a Gant chart.
Plus, prepare for stories of reindeers high... despite their apparent immunity to their favourite hallucinogenic mushroom treats. And we burrow into Santa’s iconic beard to find any microbial magic that lives there.
And yet more reindeer magic, this time the mysteries of their amazing body clocks, which they seem to be able to switch on and off at will... AND we reveal Rudolf the red nose reindeer’s big secret. You’ll never hear that song in the same way again

Totally bananas
12/13/2024
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?

Going home
12/6/2024
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.

Doing a Deal
11/29/2024
It’s Black Friday! Everyone’s camping in the street, staying up all night for the very best deals around. And Unexpected Elements are joining in.
We take a look at the huge underground trade of vital resources...not run by criminals but fungi.
Then it’s onto illegal animal trade and the 300 pets who got a terrible deal, strapped to a man’s chest as he tried to make it through airport security.
Have you ever asked a pigeon for advice when gambling? We hear from a professor of psychology about why you shouldn’t.
And finally, the story of Lee Sedol – the world’s best player of the boardgame Go, who was challenged by Google to a game worth one million dollars.
All the deals you didn’t know you wanted to hear about, and so much more!

Super Science
11/22/2024
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.

Are you not entertained?
11/15/2024
It’s been 24 years since the release of Ridley Scott’s Gladiator, which left audiences captivated by the story of Maximus the gladiator, played by Russell Crowe. Now, Gladiator II is hitting the cinemas, so this week we enter the arena to take a look at some gladiatorial science.
We hear about an angry little fish that fights off its rivals in mouth-to-mouth combat, we discover how humans have looked to nature to design better armour, and we find out about the perfume that Julius Caesar would have worn.
We also speak to Dr Chris Nowinski, a former WWE professional wrestler who's now a pioneering neuroscientist. He’s leading some research into how to prevent concussions in sport, and is co-founder of The Concussion Legacy Foundation.
That, plus many more Unexpected Elements.

Supermassive numbers
11/8/2024
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?

The Swing of Things
11/1/2024
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.

Mystery blobs
10/25/2024
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.

TV made me do it
10/18/2024
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.

The world's longest treasure hunt
10/11/2024
After 31 years, a mammoth treasure hunt consisting of solving eleven cryptic clues has finally concluded. 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.
