Episodes

The Swing of Things

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 ...

Mystery blobs

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 s...

TV made me do it

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 mobi...

The world's longest treasure hunt

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 astrobi...

Science to make you smile

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 inv...

Shiny: Why we are dazzled by new sparkly things

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 ...

Ngā Wai Hono i te Pō: The new Māori Kuini

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 ...

Thrillseekers

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 e...

The world's worst tourist

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 ...

A sticky situation

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 fi...

The only one

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, ...

Let them eat crab

This week we’re inspired by the price of a lobster dinner fit for a king. The recently revealed price tag for President Macron’s banquet back at the end of 2023, about half a million dollars, kickstarts an Unexpected Elements challenge – can the team create something similar and manage to save not only cash, but an Italian ecosystem from an American invader? And waste not want not as we discover how the bits of a crustacean dinner you’d usually throw in the bin may be the key to a new generation...

Can I eat it?

Champagne has been discovered in a 100+ year old shipwreck. It's an amazing find. But can you drink it? Speaking of bubbly, we learn more about the physics of bubbles, and why understanding it is crucial for the climate. Also on the show, a 2,000 year-old mystery about a navigation device that persists up to the present day.

Breaking, climbing, and surfing

This week the panel take a look at their favourites of the newer Olympic sports as Paris 2024 gets underway. Surfing will happen in Tahiti this year, but could it ever be held on Titan, in orbit around Saturn? Obviously very unlikely, but not for the reasons you might expect. No vertebrate on earth can rock-climb like a gecko. Can nanomaterials come to our aid? And Amy Pope, Principal Lecturer of Physics and Astronomy, Clemson University helps us understand the physics challenges the B-boys and ...

Marriage madness

Radhika Merchant has married her partner Anant Ambani, the youngest son of Asia’s richest man, Mukesh Ambani. When your Dad is the 11th richest person in the world, worth over $112bn, you can afford a wedding year, rather than a wedding day, right? After seven months of celebration, Marnie and the panel review the festivities to see if there is any science lingering under the ‘I dos’. Hear of Hindu wedding customs and superstitions, and why something called evolutionary lag might be behind tradi...

Political Jet Lag

In the lead up to the US election President Joe Biden admitted to ‘screwing up’ in a debate against Donald Trump. His excuse? Several trips around the world, a cold and severe jet lag. Joe has Marnie and the panel wondering how we can fly better. We’ll be stopping off to hear how one species, much like the US president, should consider reducing its airmiles, if only to avoid a pointless 16,000km round trip every year. There’ll also be a stopover in Northern Canada to hear how thinning ice is mak...

Mushroom magic

In Australia, more than six people were hospitalised suffering from hallucinations and persistent vomiting. The thing they all had in common? They ate a specific brand of hemp-infused mushroom gummies, which have since been recalled. But why take mushroom supplements in the first place? Social media claims fungi harnesses the power to unlock your hidden potential, to increase concentration and reduce stress. This week’s panel looks into the evidence. Will these claims crumble under scrutiny? Pro...

Lights out

A nationwide power outage in Ecuador left 18 million people in the dark, shutting down traffic lights and the capital’s subway system. But Ecuador isn’t the only place dealing with blackouts. In Nunavut, Canada, where panelist Meral Jamal lives, power outages happen frequently, including as she was preparing for this programme. How do you deal with a power outage in a remote place? And how did the Inuit manage the cold winter months without electricity at all? What is the darkest colour in the w...

Seismic swift

At a recent Taylor Swift concert in Scotland, seismographs measured a “Swift Quake” caused by foot-stomping fans. But this wasn’t the only star that has made the ground shake - there have been several others, including Travis Scott and Bruce Springsteen. Could this power be harnessed in some way? Turning our attention to non-popstar quakes, there are some animals that seem to predict earthquakes. A pond in Italy, usually filled with toads during breeding season, was suddenly void of them shortly...

An unexpected burger

Could a scientific burger compete against the fast food giants? We fear not! You will need: • Meat - A tick capable of inducing alpha gal syndrome, a disease that makes you allergic to red meat. • Garnish - Lettuce grown in space. (WARNING: it is more susceptible to bacterial infection than that grown on Earth). • Buns - A short but thick guide to the human buttocks with Heather Radke. Why do we humans have such large behinds? • Something sweet - We chose the humble baobab seed. An unusual tree ...

Balloon manoeuvres

After North Korean balloons delivered trash to South Korea, we explore balloons of all kinds, why they can be useful, and when they’re not. Scientists have been using balloons for a long time, from pig bladders dropped from great heights, to Michael Faraday inventing the rubber balloon. Floating through the air seems like a great, energy-efficient way to fly. So why isn’t the sky full of airships? And party balloons are fun… but do we want to waste our precious helium on parties? What is this li...

Eternal flames

As the Olympic torch makes its way through France, we investigate the fires that continually smoulder and those which are stomped out. You might expect snow to make a solid fire extinguisher, but in Canada, it is somehow keeping embers alight. These ‘Zombie fires’ keep burning through the winter, releasing huge amounts of carbon into the air and enhancing the tinderbox for summer wildfires. While wildfires leave trails of destruction, for some plants and animals, they act as a catalyst for life ...

A world going on underground

How would you feel if you spent more and more of your life underground? Could that be how more and more of us live in the future? Presenter Marnie Chesterton and panellists Candice Bailey in Johannesburg, South Africa and Tristan Ahtone in Helsinki, Finland dig into subterranean science. Did you know around a million people live underground in China's capital Beijing? Have you heard of the race to dig the deepest hole in the Earth? In this episode we explore how humans have been digging deep for...

Winning Losers

In a competitive world, is it always best to finish first? A tribute to second place, second thoughts, and second opinions. You might assume that Olympic gold medallists have more successful lives than their silver-placed competitors. A study shows that on average winners die a year younger than the runners up, and earn less money. In the invasive jelly-fish wars of the Black Sea of recent years, it seems the second-comers prevailed over the voracious first-timers. And what about siblings? Does ...

Computer memories and quantum futures

These days, over a trillion semiconductor microchips are made and shipped each year. The industry is worth eye-watering amounts, and since the 2020-2023 global shortage, nearly all governments are trying to get a slice of the industrial wafer. But what was it like just 40 years ago trying to get yourself a home computer when your communist leaders didn’t approve, and there were nowhere enough devices to go round anyway? Andrada Fiscutean spoke to some of the bootleggers. These days, not only are...
