Breaking, climbing, and surfing

This week the panel take a look at their favourites of the newer Olympic sports as Paris 2024 gets underway. Surfing will happen in Tahiti this year, but could it ever be held on Titan, in orbit around Saturn? Obviously very unlikely, but not for the reasons you might expect. No vertebrate on earth can rock-climb like a gecko. Can nanomaterials come to our aid? And Amy Pope, Principal Lecturer of Physics and Astronomy, Clemson University helps us understand the physics challenges the B-boys and girls are maybe subconsciously putting themselves through as Break Dancing makes its Olympic debut. Also, climate change unearths some of our oldest fossils in Brazil, being scared of long words, and designing cities to be cooler. Presented by Marnie Chesterton, with Philistiah Mwatee and Camilla Mota. Produced by Alex Mansfield with Harrison Lewis, Dan Welsh and Noa Dowling. ... Read more

Marriage madness

Radhika Merchant has married her partner Anant Ambani, the youngest son of Asia’s richest man, Mukesh Ambani. When your Dad is the 11th richest person in the world, worth over $112bn, you can afford a wedding year, rather than a wedding day, right? After seven months of celebration, Marnie and the panel review the festivities to see if there is any science lingering under the ‘I dos’. Hear of Hindu wedding customs and superstitions, and why something called evolutionary lag might be behind traditions that make very little sense. Also, rings, but not the wedding bands. Professor Valerie Trouet, from the Laboratory of Tree Ring Research at the University of Arizona tells tales of the ancient circles found within trees harbouring secrets of climates past and future. Plus sleep divorce, why it might be a marriage saver, and finally putting to bed who has the best sleep pattern, the night owls or the early birds.

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.

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.

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.

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. Sound engineer: Emily Preston ... Read more

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!

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.

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.
