Unexpected Elements

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...

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...

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’s time for an unexpected celebration and we look to science for advice on clothes, cake and how presenter Marnie and panellists Christine and Candice can improve their singing.

The Unexpected library harbours secrets of paranormal experimentation and dead air live on the BBC, and panellist Phillys Mwatee reveals...

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 devi...

Beyonce's new album tops the charts with a reappraisal of who can do country music and the Unexpected Elements team has a hoedown.

Psychologist Sandra Obradović drops in to share some of her expertise in the psychology of v...

Can you put a price on the perfect athlete? In baseball you can, and that’s a $700 million dollar contract. Shoehi Ohtani took to the field in Seoul for the LA Dodgers to prove that the big cheque was worth it. It has Marnie asking – can you predict if one of your kids will become the G.O.A.T – the Greatest of All Time in any sport? She’ll also be investigating the other kind of goat – I'd say ord...

In a week of headlines about water shortages slowing ships in the Panama Canal and drought in India's Silicon Valley, we look at unexpected ways to manage the world’s water. Presenter Marnie Chesterton and panellists Chhavi Sachdev in Mumbai, India, and Meral Jamal in Nunavut, Canada, tell stories of innovative ideas being tried in their parts of the world. Marnie meets water detective Barbara She...

Passionate K-Pop fans send us on a journey into the science of fandom. Panellists Andrada Fiskutean in Bucharest, Romania and Tristan Ahtone in Helsinki, Finland bring us stories of Star Trek’s sci-fi utopias, why allegiances affect our behaviour and how a cunning sea creature chooses which side of itself to reveal. Presenter Marnie Chesterton meets one of her heroes - American theoretical cosmolo...

As award season reaches its climax in the US, Unexpected Elements holds its own glitzy ceremony. Which bit of science will win Best Picture? Who will take home the Best Supporting Actor? And will Prof Elaine Chew play us out with her Best Original Music? The nominations include a particularly noisy tiny fish, a sweating mannequin, and a composition based on a misbehaving heartbeat. All this plus y...

As the leap year helps to keep us in sync with the sun, we turn our attention to the natural world. There is no simple solution to stop forces like climate change that are sending nature out of sync. We’re seeing flowers such as Japan’s famous cherry blossom blooming early because of warmer weather. Some pollinators are emerging only to find the plants they rely on have been and gone. But, within...

A scientific tribute to to the successes and potential of Kelvin Kiptum, the best marathon runner to ever take to the roads.

Ahead of international Random Acts of Kindness Day, Marnie Chesterton and an invited panel look at some of the science behind nature’s better nature. Are mother spiders in Africa behind the ultimate act of kindness? How are lightning and lava lamps involved in the quest for a truly random number? And the engineer trying to bring more compassion to the machines we use every day. We also hear about...

Brain implants have been sparking conversation about the future of humanity after Elon Musk's company Neuralink announced it has embedded a microchip in a human skull. It has fired up people's imaginations and led some to wonder whether these devices that connect to our brain could be a stepping stone towards the ideas more often found in sci-fi, and maybe even create a tool to read people's thoug...

This week, the world’s largest cruise ship set sail from Miami. Whilst a cruise holiday may be appealing to some, there is also a long history of disease spreading around the world via ships. Marnie and the panel take a look at the reasons why and the resulting impact on public health policies. It’s not just humans and microbes that are hitching a ride aboard sea vessels. Animals such as mussels c...

This week on the show that brings you the science behind the news, we’re looking at news that China’s population has fallen for the second year running. Worrying news for China’s economy, but would a declining population be a good thing for the planet? The Unexpected Elements team on three continents meet the musical frogs who are having to climb a mountain to keep their populations stable, and di...

As France's youthful new Prime Minister gets his feet under the desk, we examine how stress and strains can change the way we look. We also ask what the late nights and lack of sleep that go hand in hand with leadership can mean for the health of the human body and we hear how measuring intelligence in young people isn't as straightforward as it might seem.

Could geopolitical tensions around the Red Sea affect research into the region’s heat-resistant super corals? Also on the program, what an ocean that used to lie under the Himalayas can tell us about evolution, the fruit chat continues with the latest chapter in the bananadine saga, and how looking to the past could help create the shipping of the future.

From the abolition of the leap second, to how some people feel they can actually see time stretching before them, to a festival of lunar-loving worms. On the anniversary of the invention of the word “robot”, we discuss EU AI legislation and its parallels with science fiction of a century ago, regal...

Usually Unexpected Elements looks at the science behind the news, but this week Marnie Chesterton and Caroline Steel are looking back at some of the best bits from our first few months. We’ve got the best from our team of panellists across the globe, including what’s going on in your brain when you speak more than one language, the horrific mating ritual of the bedbug and the science behind our pa...

In the week of the solstice – the shortest or longest day of the year depending on your latitude - Unexpected Elements brings you tales of darkness and light. We hear about the dark history of sensory deprivation studies and why up until now, we’ve been in the dark about light’s role in the fairly fundamental process of evaporation. We’ll be shining a light on the darkest oceans, meeting the fanta...

On the 75th anniversary of the Universal Declaration Of Human Rights, we look into the phenomenon of caring for things outside of ourselves – whether it’s human rights, the environment, or even odd sports.
