Hannah Fry and Dara Ó Briain tackle listeners' conundrums with the power of science!

4 JANV.

13. The Fastest Fly

The buzz of a fly hovering just above your head has got to be one of the most irritating sounds around, but this week we try to work out just how fast they could be flying. Could a claim horseflies reach speeds of up to 90 mph possibly be true, and Dara wants to know if this is what makes them so difficult to swat? Entomologist Erica McAlister is better known as the ‘fly lady’ and speaks up in defence of these tiny creatures, explaining there are 7,000 known species in the UK alone. Which makes it all the more shocking there are several that don’t have wings. For Professor Graham Taylor the question of speed comes down to a simple calculation, and the team try to work out whether a horsefly beats its wings fast enough relative to its size to travel so rapidly. He explains horseflies aren't clever, but scientists are interested in their simple brains and are studying them to use as models for drones and mini robots.

12. Bored to Death

Anyone who has ever done a long car journey with kids will be familiar with the idea of being bored to death – but can this feeling really be fatal? Hannah and Dara hear about a club where members count roundabouts and collect milk bottle tops, but boredom expert Wijnand van Tilburg explains these dull-sounding hobbies might actually have mental health benefits. He explains that science and comedy are stereotypically both seen as exciting subjects but warns them their chat about Venn diagrams might tip the balance the other way. Mind-wandering specialist Mike Esterman reveals why we're rubbish at staying on task when there are more rewarding things to do, and sets the pair a challenge to play a computer game that distracts them with pictures of cute babies and fluffy animals.

11. Freeze Me When I Die

When you die, would you want to be frozen so that one day you might be brought back to life? Listener Elspeth wants to know if that’s even possible. So Hannah and Dara embark on a quest to explore the chiling science of ‘cryobiology’: preserving living things at really low temperatures. It turns out there are already thousands of people alive who were once suspended in antifreeze and stored in liquid nitrogen - when they were just a small clump of cells! There’s even a frog which can turn into a ‘frogsicle’ for months on end. But re-animating full size humans is a challenge no one has solved…yet. Will some miraculous nanotechnology of a distant future solve the problem?

10. Night Walkers

Wake up! It’s time for a dreamy new episode of Curious Cases all about the science of sleepwalking. Listener Abigail has done some strange things in her sleep, from taking all the pictures off the wall, to searching for Turkish language courses. And she wants to know: WHY IS THIS HAPPENING? It turns out Abigail is not alone. Hannah and Dara hear weird and wonderful stories of extreme sleepwalkers - from the lady who went on midnight motorbike excursions, to the artist who does all his best work while asleep. They delve into the neuroscience to find out how you can remain in deep sleep while walking, talking or even peeing in your mum's shopping basket. They learn about some cutting edge research where the participants were sleep deprived and then half-woken with scary sounds, and they zero in on the key triggers, from a boozy night out to a squeaky bed. Contributors Professor Russell Foster: University of Oxford. Professor Guy Leschziner: King’s College London and Guys’ and St Thomas’ hospital Lee Hadwin: the sleep artist Professor Francesca Siclari: The Netherlands Institute for Neuroscience Producer: Ilan Goodman Executive Producer: Alexandra Feachem A BBC Studios Audio Production

9. A lemon-powered spaceship

Fruit-powered batteries are the ultimate school science experiment, but they’re normally used to power a pocket calculator. This week’s listener wants to know if they could do more, and sends the team on a quest to discover whether they could used to send a rocket into space? Professor Saiful Islam is the Guinness World Record holder for the highest voltage from a fruit-based battery, but disappoints the team when he reveals they produce very little power. He used 3,000 of them and only managed a measly 2 Watts. Given that spaceships are famously difficult to get off the ground, it seems a lemon battery might just fail the acid test. Author Randall Munroe is undeterred and suggests alternative ways to get energy from citrus, including burying them to make oil. Then the team discuss the pros and cons of switching to a lemon-based diet. For battery expert Paul Shearing, all this raises a serious question, about how we will power the planes of the future. He suggests solar power could play a part in short-haul flights and discusses some of the exciting battery materials being tested today.

8. Be More Athlete

Are you more of a rhino or a kitten? More like a tortoise or a hare? Listener Ivy wants to know what makes a good athlete and so Hannah and Dara tackle the science of sport. Our curious duo get to grips with the rigours of training tailored for endurance events vs those based on more explosive bursts of activity. They consider the contribution of genetics, fast vs slow twitch muscle fibres, the unique advantage of Michael Phelps's body proportions and whether butterfly really is the most ridiculous stroke in swimming. And after a rigorous scientific analysis, Dara turns out to be ideally suited for…netball. Much to his surprise.

7. Invincible Moss Piglets

Listener Vivienne has heard that tardigrades - aka moss piglets - have special powers of survival. Radiation? Drought? Extreme cold? NO PROBLEM. Does that mean they could survive an apocalypse? And could they even help us master space travel!? Hannah and Dara learn how to find these little moss piggies in roof gutters and garden corners. And they're amazed by their capacity to dry out and hunker down for decades before springing back to life. But calamity strikes when it turns out that fine glass tubing - in the form of pipettes - is their natural predator. And worse is to come: our curious duo learn that there may be some tardigrades stuck on the moon, and one researcher has even fired them out of a gun. All in the name of science. But they have survived at least 5 mass extinctions so far. So their chances of surviving the next one are pretty good. As long as pipettes aren't involved.

6. The Shock Factor

If there’s one type of discharge you really want to avoid, it’s lightning, but what happens when it hits you? We hear from lightning survivor Kerry Evans, and discover that the best place to shelter – if you ever find yourself in a similarly charged storm – is in a car, or low to the ground. And why this is never a good time to take a selfie. Dr Dan Mitchard from Cardiff University’s excitingly-named Lightning Lab explains why there's no lightning at the poles, and the presenters lament that polar bears and penguins are missing out. We all know about the gods of lightning, but the mysticism doesn't stop there. Above cloud level there are many other types of unusually-named phenomena, reaching to the edge of space, including sprites, trolls and even pixies. And Professor Karen Aplin reveals that lightning has even been discovered on other planets, in a science story that could affect our plans to colonise Mars.

At 25, Hannah’s life begins falling apart. An anonymous intruder has made her phone her enemy. Aided by the technology we all rely on, this intruder is watching Hannah, threatening her, even pretending to be her. Feeling increasingly unsafe, Hannah goes to the police, but they can’t stop it. Worse, they don’t even recognise it for what it is: stalking. Hannah doesn’t know for sure who is behind it all, but she suspects an older man she met more than two years earlier at London Fashion Week. Initially, he claimed to have been hacked. Even today, he disputes stalking her. To make sense of what’s happening Hannah turns to a woman she’s known since she was seven years-old, and who also happens to be an investigative journalist. Together with her “ex-step mum” Carole Cadwalladr, they set out to piece together something the police couldn’t: the true identity of Hannah’s stalker. Doing so means untangling a web of deception spanning continents. On her suspected stalker’s trail, Hannah realises nothing about them is as she first thought.

ACTUALITÉS DU JOUR
Peak Danger is Season 2 of Extreme, the BBC podcast about those who chase the impossible... who strive for superhuman status and refuse to accept that life has any limits. Every season tells an unforgettable, action-packed story about people who’ve pushed their minds and bodies to the very edge – but at what cost? A mountain of trouble... In August 2008, around 30 climbers took on K2. Over 2 disastrous days, 11 of those people would lose their lives. This is the story of what really happened. Sitting on the border between China and Pakistan, K2 is a perfect pyramid that pierces through the clouds. It looks like a kid’s drawing of a mountain…but this terrifying peak is anything but child’s play. Newlyweds Cecilie Skog and her husband Rolf Bae loved climbing mountains almost as much as they loved one another. In the summer of 2008, they embarked on a honeymoon like no other, when they decided to climb K2. What happened next would change their lives and the lives of everyone around them…forever. A devastating avalanche scatters high altitude climbers across K2’s steep slopes. Life and death rescue missions quickly get underway. Who can be saved… before time runs out? Historian and podcaster Natalia Mehlman Petrzela returns with a sky-high story of human vs nature, and of survival against all the odds. What does it really take to push yourself to the brink of human possibility? How does it feel to stand with the whole world at your feet? And is it ever worth risking death… in order to feel alive?

JOURNAUX PERSONNELS
The comedy podcast that takes history seriously. In each episode of You’re Dead to Me from BBC Radio 4, Greg Jenner is joined by a comedian and an expert historian to learn and laugh about the past. History isn’t just about dates and textbooks – it’s about extraordinary characters, amazing stories, and some very questionable fashion choices. How long did it take to build an Egyptian pyramid? What does the Bayeux Tapestry reveal about medieval life? Why did it take nearly half a millennium for Joan of Arc to become a saint? And was Catherine the Great really all that great? Whether you want to explore ancient landmarks like Stonehenge and Machu Picchu, dance through the history of Broadway and Bollywood, or find out how the Tudors rose to power, Greg and his guests promise to teach you something new that you won’t have heard in history lessons. Previous episodes of You’re Dead To Me have covered everything from royals to revolutionaries, actors to activists and divas to dictators. Take a stroll through the history of high-heeled shoes or get the scoop on the history of ice cream. Maybe you’d like to paint like the cave artists of the Palaeolithic era, work out like a Victorian bodybuilder, or fight like a Spartan? We’ve even hosted a special, live episode with the BBC Concert Orchestra to explore the dramatic life of Wolfgang Amadeus Mozart. Whatever your historical interests, Greg and his guests make even the trickiest topics easy to follow. Join them for a history lesson that’s as entertaining as it is enlightening - with no homework required.
