Super Science Nov 22, 2024

Show notes

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? Nov 15, 2024

Show notes

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 Nov 08, 2024

Show notes

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 Nov 01, 2024

Show notes

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 Oct 25, 2024

Show notes

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.

Presenter: Marnie Chesterton, with Camilla Mota and Phyllis Mwatee Producer: Emily Knight, with Alice Lipscombe-Southwell, Eliane Glaser and Noa Dowling Sound engineer: Gareth Tyrrell

TV made me do it Oct 18, 2024

Show notes

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 Oct 11, 2024

Show notes

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.

Presenter: Marnie Chesterton Panel: Chhavi Sachdev + Tristan Ahtone Producer: Julia Ravey Production team: Harrison Lewis, Jonathan Blackwell + Tom Taylor Studio Engineer: Gavin Wong

Science to make you smile Oct 04, 2024

Show notes

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.

All things Oregon! Sep 27, 2024

Show notes

Join Marnie Chesterton and her panel of science journalists Chhavi Sachdev and Jes Burns, on their Oregon science mission. We investigate building materials of the future, from creative cement alternatives to buildings made of wood, and hear from forest scientist Sarah Jovan about how one humble plant has made huge changes to Portland's air quality.

Plus, we make waves with a new wave energy testing facility, uncover the benefits (or costs) of bamboo alternatives and our panellist fight against the clock to pitch what they think should take the crown of Oregon's Coolest Science. And, we hear from our studio audience about how they experience the world and one of them even volunteers to do the fact file. Recorded at Oregon Public Broadcasting (OPB) studios in Portland Oregon. Presenter: Marnie Chesterton Producer: Julia Ravey Production team: Alex Mansfield and Cathy Edwards Studio engineer: Kate Barker and Darren Wardrobe

Shiny: Why we are dazzled by new sparkly things Sep 20, 2024

Show notes

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?

Presenter: Caroline Steel, with Kai Kupferschmidt and Phyllis Mwatee Producer: Harrison Lewis, with Emily Knight, Noa Dowling and Elizabeth Barsotti Sound engineer: Searle Whittney
