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 the technology helping archaeologists discover lost worlds in South America, the maths that might be...

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 thoughts. Marnie Chesterton and the panel discuss whether our privacy is at risk or whether we are alread...

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 can cling on to ship hulls, exposing previously pristine environments to potentially invasive species...

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 dig deep to explore the earth’s declining microbiome and the hope scientists have for the future. As t...

As the new year arrives for much of the world, Marnie and pals look at a few time-related oddities. 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 handedness, Arctic golf courses and the time-capsule of all humanity, stuck to the side of the Voyag...

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 fantastical creatures who can turn their bodies into flashlights. Our Under the Radar story this week als...

After 41 Indian miners were happily rescued last week, Unexpected Elements takes a look at how our futures might lie below the surface. As climate change suggests more of our infrastructures need to be buried safely, and even living spaces could be cooler down there, we discuss future technologies for digging tunnels more safely and cleanly. But tunnelling and boring could go back a long way - more evidence suggests species of dinosaurs used to to live semi-subterranean lives. Tunnelling also ha...

This week on the show that brings you the science behind the news, inspired by COP28, we’re talking about meetings. Honestly, it’s way more interesting than it sounds. Come to hear about blackworm blobs – a wormy meeting that only happens in stressful situations - and how scientists are taking inspiration from it to design robots. Stay for the stories from nature where species are missing crucial pollination meetings thanks to that global stressful situation that is climate change. And what’s be...

To mark UN World Toilet Day on 19 Nov, Alex Lathbridge discusses all things toilet related with Andrada Fiscutean and Tristan Ahtone, as they attempt to lift the lid on our collective taboo of discussing sanitary matters. In 2020, 3.6 billion people – nearly half the global population – lacked access to safely managed sanitation. Diseases such as cholera, typhoid, dysentery, and diarrhoea can spread amongst populations who still practice open defecation. And lack of access to a functioning toile...

This week on the show with the science behind the news, we’re looking at a story that has sparked a debate in India about a 70-hour work week. In an interview, the billionaire NR Narayana Murthy said that young people should be ready to work 70 hours a week to help the country's development, suggesting that unless productivity improved, India would not be able to compete with other countries. But if you work twice as long, do you get twice as much done? The Unexpected Elements team on three cont...

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 driving ...

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 wastewater ...

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 that a...

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: Alex M...

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 chan...

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 team? W...

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 on a ...

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 Dr Har...

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 biological algor...

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 mu...

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 evolved ove...
