In the week where many celebrated Halloween we are wondering about that tingle down your spine, the dryness in your mouth, the racing pulse - might it actually be good for you? We also look into a special frequency of sound, just below our human hearing range, that might cause rational people to start feeling spooky. And we explore Cryptids and the zoology of creatures that don’t really exist. Plus, if you’re bilingual, do you really have a first and second language? We also explore why...

Lagos Fashion Week makes some unexpected connections to vegan wool, 1920s car marketing, and Right to Repair legislation. If we consider our obsession with the clothes we wear to be some result of sexual selection, do any other animals evolve their self-expression with such frequency? Dr Ellen Garland of St Andrew’s University tells how male humpback whales change their song with surprisingly infectious rapidity, and talks us through some recent hits. Also, some catalytic promise for...

According to the pop icon Madonna, music makes the people come together. But can we prove that using science? As Madonna embarks on her greatest hits world tour, the Unexpected Elements team on three continents take some of those hits and examine the science behind them. Like a Virgin take us on an excursion into parthenogenesis, and the Komodo Dragons that can reproduce without the inconvenience of having to find a mate. Madonna sung about travelling ‘quicker than a ray of light’, but is...

How did bedbugs become a global concern? We examine why their unconventional reproduction methods are so successful, how bedbugs and humans even crossed paths in the first place and what public health has to do with nation building. Also on the show, we look at why there's no human version of dog food, how conspiracy theories take hold, and the legal wranglings over an old Canadian oil pipeline.

How would it feel wake up years later? After the US narrowly avoided a government shutdown, we look at how complicated systems - such as living things - can just press pause. Could humans ever hibernate like bears and squirrels? Or even like simpler animals that can be revived after 46,000 years. Also, which way does antimatter fall under gravity? And how might IVF save a functionally extinct species of rhino? Presenter: Caroline Steel, with Chhavi Sachdev and Philistiah Mwatee. Producer:...

This week on the show that brings you the science behind the news, there are lots of stories about inflation in economies across the world. When inflation happens your money doesn’t go as far, so what does psychology say about how much money you really need to make you happy? We humans aren’t the only ones experiencing inflation either, trees are suffering from it too. We find out what happens when the balance of supply and demand of nutrients between trees and fungi is disrupted by climate...

How does our brain process language? We speak to an expert who is using technology to turn narrative thoughts into text. Also on the show, what is happening in our brains when we switch languages? And what are the positives and perils of technology and translation? Also on the show, we look at internet connectivity in incredibly remote areas, whether carbon capture is realistic, and we continue to explore different foods from around the world.

In a week where global heat records have melted, we find out how that can make fish life-threateningly stupid. We also dive a little deeper to find the part of the ocean where a little heat proves life-enhancing. And we bring you boring science… no, not in that way. Find out what tree rings can tell us about ancient civilizations and past climates. Also, a new Japanese mission aims to park nice and neatly on the moon – how different is that from the famous first effort from the Apollo 11...

Following recent coups in Niger and Gabon, and with seven African coups in the last three years, some political commentators are suggesting that there might be an epidemic of coups. But are coups really contagious, and what does the political science say? Caroline Steel and the Unexpected Elements team across three different continents go on a quest to find the science lurking behind the news. We find out what trees in Chile can tell us about coups and we meet the wasp that performs a coup...

India's successful moon landing has the Unexpected Elements team engaging in some serious lunacy. We look at where the moon even came from, how it helps us navigate, and whether it has a cultural and ecological heritage. Also on the show, is Dr. TikTok leading to a raft of self-diagnoses, should we be eating banana peels and worms, and we go back to the moon to see if it has any effect on our sleep.

This week, we start off by digging into conspiracy theories. What’s behind their enduring allure? And have they always been around? Marnie and the panel investigate. Many conspiracy theories are based off of misinformation… but what’s actually going on in our brains when we lie? We look into the case of the man who was physically unable of spreading tall tales. Sometimes, the truth is there, but is difficult to uncover. Delving for this deeper meaning is something particle physicists like...

The conversation this week starts off on corruption. There are allegations of political or corporate malfeasance in the news regularly throughout the world. But can science bring anything to the investigators? We look at some efforts to bring empirical rigour to the fight. But corruption of sorts is also a big thing in our online lives. Algorithms can deliver duff results, maybe because they are poorly conceived, or perhaps because they are fed corrupt data. So when our cellular...

This week on the show that looks for the science behind the news, Marnie Chesterton investigates mystery after mystery. Where is Yevegeny Prigozhin, the leader of the Wagner Group, and could science help to trace him? Which animals would do best at a game of hide and seek? And we hear about the time when half the stuff in the universe went missing, and how cosmologists found it again. We continue our endless quest to identify the Coolest Science in the World. This week’s contender studies...

The World Cup has us looking at why women get more ACL injuries, how to avoid cracking under pressure, and why some animals play dead. Also on the program we consider the pros and cons of Artificial Intelligence in Africa, whether the continent is turning to nuclear power, and if banana skins are hallucinogenic.

As Netflix cracks down on password sharing around the world - something it once encouraged - we wondered why people like to share passwords to other things, such as phones, email accounts and logins. Passwords and encryption exist as ways of protecting us from hostile agents in most aspects of life. But timing is everything. Nature has been doing it for years of course. But climate change is upsetting some of the ecological match-ups of locks and keys, migration and feeding that have...

Unexpected Elements looks for the science behind the news, and this week the news is glittery and pink with the release of the Barbie movie. The movie has very pink aesthetic, so we get philosophical about the colour pink – does it actually exist and if so, how come it isn’t in the rainbow? We also discover how this iconic doll has performed some actual valuable science, helping cryogenic researchers design space suit technology to help future missions to the moon. In Ask the Unexpected...

As Nato meets, we look at what science says about consensus decision-making, whether the universe is left-handed, and what chemistry can tell us about our ancient past. Also, we examine windfarms potentially blocking reindeer herding, our quest for the coolest science in the world continues with Beth the bee queen, and Caroline contemplates the long road that got us to a malaria vaccine.

This week time is up for the UN to come up with rules about how to mine the ocean bed. We hear about the mysterious potato shaped objects on the sea floor that contain lots of valuable minerals that are essential for electronics like mobile phones. Our team on three different continents compare how recycling of precious metals is going in their parts of world, and we hear why early Lithium batteries kept catching fire. We also speak to an expert on hydroelectric power who tells us how small...

Muslims around the world are celebrating Eid, but how to pick a date for your festivities? The Islamic calendar says look to the moon, but haven’t we always chosen to order life on earth by using the planets, moons and stars? We hear about the Mayans who tracked Venus and the astronomer who proved that comets weren’t bad omens. Having looked at the outsourcing of decisions to the sky, we wonder why we can’t just trust our brains and wonder what neuroscience has to say about it. And now...

A look at some unexpected elements of congestion: Why does pollen make so many of us wheezy, and sneezy? What can it tell us about the distant past? Plus, we take a look at what we can learn from the construction and engineering behind aquatic snot palaces. Plus your enemy’s enemy can be your friend – hear about the tiny viruses that invade certain bacteria. Speaking of bacteria, we look at the latest place to hunt for new antibiotics – the fur of a certain animal, and with reports of famine...

The show that brings you the science behind the news, with Marnie Chesterton and an inter-continental team. This week we take the headlines of the wildfires in North America, pull out the science and run with it. We explore what’s actually in smoke-polluted air, looking at the part the El Nino weather system plays in starting fires, and discover why a surprising element of air pollution is helping conservation biologists to track animals. We look at how tobacco is not just bad for your...

As French citizens protest against the raising of the state pension age, we look at the figures – are we really living longer? And if so, why? We take notes from the naked mole rat - it’s born looking wrinkled but this rodent is apparently ageless. And moving on from mere creatures, we’re asking if every state, society or civilisation has a lifespan, and if we can prevent it ending on our watch. Also, as South Africans battle to live their best lives against almost daily power cuts, we look...

Human migration is in the headlines again – India and Australia have announced a new migration deal, in the US a Covid-inspired policy that allowed migrants to be quickly expelled has come to an end, and in the UK new measures were announced to stop foreign students bringing families with them, in a bid to reduce migration figures. But what does science tell us about migration? With a team across three continents, we’re looking at the origins of human migration and exploring some of the...

On the anniversary of the first telegraph being sent, the team discover how the telegraph was used as a colonial tool in Ghana, and how an eccentric Brazilian emperor helped spark a communications revolution. They also reveal how tiny worms have helped scientists work out how our hearing works, and how bioelectricity might help focus your mind and heal your wounds. There’s a tale of evil seaweed causing havoc for coastal communities, a scientist studying misophonia makes a pitch for The...

After the elections in Thailand and Turkey, we explore the forces that shape how you decide to vote. Clue: a lot of it comes down to us being social animals. We getting stuck into various sticky subjects – the glue that holds together animal societies, the cells in our bodies and even the International Space Station. We also looking at how the blueprint of the human genome just got a whole load better. Also, join our mission to find the coolest science in the world, with the scientist who...
