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 making it difficult for local communities to remain in touch with their ancestral heritage and traditional modes of travel. Whilst we recommend considering more environmentally friendly alternatives here at Unexpected Elements Airways, we understand that some flights can’t be avoided. Take time whilst onboard to consider how you can reduce the symptoms of jetlag with tricks learnt from the latest scientific understanding of human physiology. Professor Rosemary Braun tells us how the clocklike rhythms of the body can be manipulated to make any long haul flights more manageable.Also, the smashing specificity of Wimbledon’s grass tennis courts, a grand astronomical debate from the 1920s and a very special Nunavut Day.Presenter: Marnie Chesterton Panellists: Christine Yohannes and Meral Jamal Producers: Julia Ravey, Harrison Lewis, Dan Welsh and Noa Dowling

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?Professor David Nutt pulls magic mushrooms out of the magicians hat to expose its secrets. These recreational drugs are classified as a psychedelic, causing users to hallucinate. Find out what hallucinations are and why David believes this shroom, illegal in much of the world, could become a key ingredient in medicinal treatments sometime soon.Also, the first chemist on record, how touch screens can tell the difference between your finger and an inanimate object, and why some songs get stuck between your ears.Presenter: Alex Lathbridge Panellists: Christine Yohannes and Godfred Boafo Producers: Harrison Lewis, Alice Lipscombe-Southwell, Noa Dowling and Florian Bohr

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 world? You may think it is black, but, in fact, there is something even darker – ultra-black. Deep-sea fish, butterflies, and, surprisingly, even humans have used ultra-black for a variety of purposes, like being sneaky, fashion statements, and contemporary art.But what about nature’s blackouts? Ocean scientists Allie Clement tells us about long sunless winters in Antarctica, merry midwinter celebrations, and how ecosystems in Antarctica responds to months of darkness.Also, the singular origin of a new apex predator hybrid, why alligators have such disgusting table manners, and the maths of scamming which adds up to some astonishingly big bucks.Presenter: Marnie Chesterton with Meral Jamal and Phillys Mwatee Producer: Florian Bohr with Julia Ravey, Noa Dowling and Katie Tomsett Sound engineer: Tim Heffer

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 before an earthquake hit. Are there any other animals with seismographic abilities? And is there a chance we could harness their abilities somehow?Also, tremors on the small island of Mayotte led to a surprising deep-sea discovery. Nathalie Feuillet shares some earth-shattering facts about her team’s discovery.And, to shake things up, Marnie and panel talk about the 'Frenchness' of French fries, the tech hidden inside the Euros’ footballs, and the gadgets that fools your employer into thinking you are working.Presenter: Marnie Chesterton, Godfred Boafo, Christine Yohannes Producer: Florian Bohr, Julia Ravey, Dan Welsh, Noa Dowling.

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 indigenous to Madagascar, the subject of an incredibly successful conservation project. • Fries - Of course! The humble potato is threatened by climate change, what is being done to futureproof it?Instructions: • Who are we kidding! There is no scientific method! • Bang it all together and feast your ears on this week’s show!Presenter: Marnie Chesterton Panellists: Candice Bailey and Affelia Wibisono Producers: Harrison Lewis, Julia Ravey, Ben Motley and Noa Dowling

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 limited gas worth saving for?Also, why you’re likely smarter than your grandparents were at your age, why snails climb up walls, and scientists looking at clouds from space. Presenter: MarnieChesterton Panellists: Andrada Fiscutean, Meral Jamal Guests: Prof Andrea Sella (University College London) and Prof Dave Hodgson (University of Exeter) Producer: Florian Bohr with Harrison Lewis, Julia Ravey and Noa Dowling

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 – helping them to spread their seeds or flower. And the extent of these blazes can also be marshalled by nature – with elephants and beavers building natural fire breaks into landscapes to prevent uncontrollable flames. We hear about when the first fires happened on Earth and how we can study ancient fires which have long since gone out. Plus, we unpick the key to monogamy (in mice), why cicadas love prime numbers as well as your thoughts on snakes...

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 over 3,000 years explorer Christian Clot tell us why living underground with no contact to the world above was a nicer experience that you might expect.

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 the first-born in a family really have any discernible advantage in life?Also, the potential perils of cutting-edge wearable medi-tech, the value of second opinions, and the chemical benefits of silver itself.Presented by Marnie Chesterton, with Godfred Boafo and Andrada Fiscutean Produced by Alex Mansfield, with Dan Welsh, Julia Ravey and Noa Dowling Sound by Gwynfor Jones

A scientific séance

Join the Unexpected team as they journey beyond the borders of reality to ask why we believe in the illogical. After a fraudulent psychic dupes 1.3 million Americans, panellist Camilla Mota turns to history for insight into how scientists debunk such con artists. The Unexpected library harbours secrets of paranormal experimentation and dead air live on the BBC, and panellist Phillys Mwatee reveals why our beliefs win out over hard evidence written in ink. Nevertheless, in a world rife with conspiracy and vaccine hesitancy, Melissa Kapulu from the KEMRI-Wellcome Trust Research Programme in Kilifi, Kenya, shares the fascinating scientific obstacles faced in the quest to eradicate malaria from Africa once and for all. Also hear how a Nigerian pastor and super-star has been making Melissa's job much harder, and life on fake mars.

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 computing devices in just about everyone’s hands, they are mostly interconnected to vast arrays of machines collectively forming “the cloud”, which provides so much of our economic and scientific infrastructure. It is no longer about stand alone computing. But just maybe the deep future of computing lies in using individual atoms and photons as information-bearing digits. This is the basis of “quantum computing” which could use the properties and mechanics of the quantum scale to perform hugely complicated calculations in fractions of a second. Prof David Lucas of Oxford University physics department and colleagues are building some key demonstrators of the techniques we need to master. And just recently, they built an impressive manifestation of “Blind Quantum Computing”, which just might enable something like the quantum cloud of the future.Also, we have a look at an app for modern motorists that adjusts a piece of music to react to the movement of the car. Developed by Mercedes-AMG and the rapper Will.i.am, Christine Yohannes has been thinking about drivers becoming the musical maestros of their own journeys. Presented by Alex Lathbridge, with Andrada Fiscutean and Christine Yohannes. Produced by Alex Mansfield, with Harrison Lewis and Tom Bonnett.

Beyoncé, banjos and dancing chemistry

Beyonce's new album tops the charts with a reappraisal of who can do country music and the Unexpected Elements team has a hoedown. Panellist Christine Yohannes unearths new research that changes our understanding of the origins of cowboys. Chhavi Sachdev has a thing or two to teach Beyonce as she reveals why the banjo has it's characteristic twang and we meet a man with powerful chemistry - TikTok dance sensation Dr Andre Isaacs from the College of the Holy Cross in Massachusetts tells presenter Marnie Chesterton how dancing in his lab helps explain click chemistry. We also hear how new species could be given names that refer to the locations they're found in, we discuss whether mining is causing the Earth to shrink and, of course, eclipses make an appearance. We shed some light on how an eclipse over 100 years ago helped prove Einstein's theory of relativity.

G.O.A.T

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 ordinary, but these ones are fighting wildfires. We bring you the curious tale of a never-before-seen beach pebble washing up on the shores of a remote island. What are they? And get the lowdown on the most unpleasant sounding ultramarathons after a 40-year-old Scottish woman completes a race SO hard that only 20 people have finished . Plus, gravitational waves, home-grown antivenom, and listening on double speed. Can your brain take it?

Leaping in Sync

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 the natural world, there also incredible stories of animal synchrony that offer hope and that we could learn from. We meet the Cape Ground Squirrels who appear to be adapting to sweltering summers, fireflies who offer a model for understanding the relationships between objects and hear about a ‘perfect’ solar system in which all planets are in sync.Plus, the underwater mountain range discovered in Chile, a listener asks a question about keeping time and we hear what you’ve been getting in touch about over the past week.

Going the distance

A scientific tribute to to the successes and potential of Kelvin Kiptum, the best marathon runner to ever take to the roads. Marnie and the team take time to reflect on the tragic loss after Kelvin's death and looks at the science behind his record breaking performances. Why do East African long distance runners continue to dominate the world stage? Can one group of indigenous people in the state of Chihuahua in Mexico, really run 100km without getting tired? And what makes you fall off the back of a treadmill when you just can't keep going? Is the limiting factor in endurance sports found in the body or the mind? We also hear how one small insect is having a mighty impact on African ecosystems, and Marnie ponders the future of AI. What happens when we are no longer able to trust our eyes and ears in a world of deepfakes.Presenter: Marnie Chesterton, with Philistian Mwatee and Tristan Ahtone Producer: Harrison Lewis, with Dan Welsh, Tom Bonnett, Katie Tomsett and Jack Lee

Not so random acts of kindness

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 benefit your love life, and Marnie receives her very own random act of kindness - a surprise trip to a lab to meet some of the most extraordinary creatures on the planet.Presenter: Marnie Chesterton, with Andrada Fiscutean and Camilla Mota Producer: Dan Welsh, with Tom Bonnett, Katie Tomsett and Alex Mansfield

Deep in thought

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 already an open book. They try to understand the concept of backing up our brains, and they meet Dr Michael Winding from the Francis Crick Institute in the UK to hear about a pioneering study to map the pathways of a brain, and you might be surprised how small that brain was.Plus, Katie Tomsett looks at how tattoos could be used to indicate the health of our bodies. In Under the Radar we learn how batteries could one day charge through sound, we hear the story of an alleged spy pigeon caught in India, and we highlight the wonderful tale of a beluga whale.Presenter: Marnie Chesterton, with Chhavi Sachdev and Kai Kupferschmidt Producer: Tom Bonnett, with Alex Mansfield, Dan Welsh, Katie Tomsett and Jack Lee

How plankton made mountains

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. We hear how scientists are tackling this problem with novel polymer lubricants. And we’re not done yet with marine creatures creating big issues. Professor John Parnell tells us the huge impact microscopic phytoplankton has had on Earth’s geology, and how the stuff in your pencils could actually be the bodies of long dead plankton... Plus, we explore the latest developments in rhino IVF, say ‘saluton’ to our Esperanto listeners and answer a question about going grey. And as Alabama uses nitrogen to execute a prisoner, we look at the science behind death penalty drugs.

Populations of people, frogs and microbes

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 the Africa Cup of Nations continues, we’ll be wondering how you might date a footballer. Not in a romantic sense… we hear about some suspiciously mature youth players and how science can help when the age on a passport isn’t reliable.Marnie will be wondering why Japanese men are shouting their love from a hilltop, and unpicking the recipe for a truly satisfying hug.All that plus a postbag bursting with multilingual puns, and the reason Portuguese speakers have trouble with English doors.Presented by Marnie Chesterton Produced by Ben Motley, with Alex Mansfield, Dan Welsh, Katy Tomsett and Jack Lee

Rulers and the rules of ageing

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.

Timing is everything

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 Voyager Probes.Presented by Marnie Chesterton with Meral Jamal, Andrada Fiscutean, plus Prof Anje Schutze of Texas A&M University Produced by Tom Bonnett, with Alex Mansfield and Dan Welsh

The Best of Unexpected Elements

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 panellist Camilla’s terrible haircut decision.We look back at some of the brilliant scientists we’ve spoken to, with subjects as diverse as whale song, how the entire universe was once the size of a marble, why an archaeologist hasn’t run off with all the gold he’s found and how the jewel wasp turn a cockroach into a zombie.We have ‘Under the Radar’ stories about power outages in South Africa, human ancestors from China, bringing Rhinos back to life in Kenya and how to keep everyone safe from Polar Bears in a place where there’s no phone signal.We reflect on our attempts to find the Coolest Science in the World, and whether it’s possible to pit a hurricane machine against an alternative to antibiotics.And it wouldn’t be a ‘best of’ show without a digest of all the fruit chat from throughout the year.All that plus eating glue for science, our best (or worst?) puns and some singing cows.Presented by Marnie Chesterton & Caroline Steel Produced by Ben Motley, with Tom Bonnett

A very dark day

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 also comes from the sea as we discover how fish skin is helping to treat burn victims in Brazil.We have an Ask the Unexpected question about why we don’t sneeze when we’re asleep, and more of your emails and voicenotes about obscure sports, tunnel living and earworms.We even find time to wonder why the Brazil nut isn’t called the Bolivia nut.

Boring science

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 happens at the very smallest scales and lowest temperatures, as observed this year by physicists at Innsbruck University. Dr Robert Wild of Innsbruck University in Austria describes quantum tunnelling - a crucial process that belies most chemistry and even the fusion of hydrogen in the sun, and which is increasingly becoming part of our electronic devices.Also, a new technique for monitoring the rapid evolution of the malaria parasite, your correspondence including obscure sports and asteroid fantasies, and a discussion of the difficulties of hiring a panda.

Meetings with intelligent worms

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 better for the planet, a big meeting that everyone flies to or a telephone conference with no video? In ‘Ask the Unexpected’ we answer a listener’s question about antibiotics - if there are good bacteria in the body, how do they know which ones to attack?Also, OMG it’s the OMG particle – we hear about the tiny but powerful particles that pound the planet from time to time. All that plus your emails about toilets and the rules of Cricket.Presented by Marnie Chesterton, with Chhavi Sachdev and Tristan Ahtone.Produced by Ben Motley, with Alex Mansfield and Dan Welsh.

Why we need to talk toilets

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 toilet disproportionately affects women.But even if you do have access to a flushing toilet, do you always close the lid? Researchers have measured the invisible aerosol plumes that rise up from the pan of an uncovered toilet flush, potentially spreading other communicable diseases including respiratory infections including even SARS-CoV2.But flushing toilets are resource heavy. A normal flush can use 5l of water. Could they be re-conceived?Prof Shannon Yee of Georgia Tech swings my to give us the latest on the “Reinventing the Toilet” project. Next March they hope to unveil the production model of the second generation reinvented toilet (“G2RT”). Much like other household appliances, it could run from a domestic power source, yet turn a family’s faecal matter and urine into clean water and a small amount of ash, with out the need for the grand and expensive sewage infrastructure required by more normal flushing cisterns.In the black sea meanwhile, AI is being deployed to track the dwindling populations of the beluga sturgeon, from whom the luxury food caviar is harvested.We discuss sightings of cryptids (mythical or scarcely believable animals) you have sent us, and after the announcement of the rediscovery of a rare echidna species in Indonesia, we look at how conservation and natural history expeditions have changed over the course of the broadcasting career of Sir David Attenborough.

Working 70 hours a week

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 continents look at research that sheds light on whether a 70 hour working week is actually as productive as Mr Murthy suggests.And if you’re working all the time there’s less time for sleep – we hear about the marine mammals that manage on 2 hours a day, and the Inuit hunters in northern Canada who follow a similar pattern.We’re also joined by Environmental Economist Matthew Agarwala, wondering whether traditional notions of productivity ignore the issues of the climate and well-being.Our ‘Under the Radar’ story this week is from Kenya, where Trachoma - a bacterial infection – is still causing people to become blind. It’s one of a group of a diseases known as ‘neglected tropical diseases’, but why are they neglected, and what can we do about it?In ‘Ask the Unexpected’ a listener wonders why eating makes some pregnant women sick and not others. We ask an expert for the answer, and we discover that the menopause is not as unique to humans as we used to think.All that plus your emails and messages, including a listener who left a cult as a result of learning another language, and the mystery of the Eastern Australian Panther.Presented by Marnie Chesterton, with Phillys Mwatee and Meral Jamal.Produced by Ben Motley, with Alex Mansfield and Tom Bonnett.

Scary science

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 a taxi is a workout for your brain and look at the benefits and pitfalls of cycling around the world.Presenter: Marnie Chesterton, with Camilla Mota and Godfred Boafo.Producer: Margaret Sessa-Hawkins, with Alex Mansfield, Tom Bonnett and Ben Motley

Fashion to dye for

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 management, and how choosing a language in which to think changes your decision making. Plus, this week’s messages from you, and can poetry help science?Presenter: Caroline Steel, with Chhavi Sachdev and Godfred Boafo Producer: Alex Mansfield, with Tom Bonnet and Margaret Sessa-Hawkins

Putting Madonna to the test

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 actually possible? We take a very fast trip through the strange world of warp bubbles.And we Get Into the Groove with the physicist who created a record so tiny it fits into one of the grooves of a normal record.We also hear about the “find your ancestry” kits that have the capacity to solve so-called cold cases, identifying unknown human remains often decades old. With the eyes of the world on events in Gaza, we discover how tech can help make sure that any reportage – video or photos – are accurate and not doctored. All that plus your emails and WhatsApps, and a listener wonders whether fish can drown.Presented by Marnie Chesterton, with Philistiah Mwatee and Katie Silver Produced by Ben Motley, with Alex Mansfield, Tom Bonnett, Sophie Ormiston and Margaret Sessa Hawkins

How bedbugs took over the world

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.

Complete shutdown

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.

How inflation affects the entire cosmos

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 change.And then we take a look at the bigger picture - the much bigger picture - as cosmologist Ghazal Geshnizjani tells us about how the entire universe once existed in a space smaller than a marble.Plus, are Romanian bear populations inflating? We probe a scientist about spider webs – why do they look the way they do? And we look at vaping – it’s illegal in some countries while smokers in other countries are encouraged to take it up. All that plus your emails, WhatsApps and some unexpected elephants.Presenter: Caroline Steel, with Godfred Boafo and Andrada Fiscutean.Produced by Ben Motley, with Alex Mansfield, Sophie Ormiston and Margaret Sessa Hawkins.

Can technology read our mind?

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.

Forgetful fish, telescopic worms and bad air days

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? We hear about an unwelcome Delhi resident that’s taking years off locals lives – air pollution. And what is a “supervolcano” and how likely is it that one ruins our run as dominant species on this planet?Presented by Marnie Chesterton With Chhavi Sachdev and Tristan AhtoneProducers: Alex Mansfield, Ben Motley, Sophie Ormiston, Emily Bird and Patrick Hughes

Zombies, cows and coups

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 poor unsuspecting cockroach, turning it into a zombie and eating it alive. There’s light relief in the form of cows listening to classical music, the answer to a listener question about carbon capture and reflections on efforts to rid the world of plastic bags.All that plus your emails, whatsapps, and more fruit chat than you can shake a banana skin at.Presented by Caroline SteelProduced by Ben Motley, with Margaret Sessa Hawkins and Sophie Ormiston

Protecting the Moon

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.

The man who couldn’t lie

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 Harry Cliff have been doing for decades. Harry tells us where we are in the ongoing quest to understand our Universe. Also, we hear the ingenious way Costa Rican scientists are dealing with pineapple waste, and we answer a South African listener’s question about evolution.

Corrupted thinking and cancerous co-option

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 algorithms are corrupted, our health is affected. Can cancerous tumours be considered corrupt organs, co-opting healthy cells to assist in their nefarious ends? Dr Ilaria Malanchi of the Crick Institute in London muses on the commonalities. Also, a look at the politicisation of pre-human palaeontology and how our stories of human origins have been, and in some ways still are, connected with nationalist geographical identities that mainstream science doesn't recognize.

Some of our universe is missing

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 murky side of the genome – dark DNA. Plus the low-down on the indefinite doctor’s strike in Nigeria, we look behind the latest news about our warming oceans and have you ever felt someone else’s pain? You might be the 1 in 50 people known as mirror touch synaesthetes.All that plus your emails, whatsapps and even more fruit chat.Presented by Marnie Chesterton Produced by Ben Motley, with Margaret Sessa Hawkins, Alex Mansfield, Sophie Ormiston, Katie Tomsett and Florence Thompson.
