One winter morning, listener Jane opened her curtains to find her car roof covered in breathtaking, fern-like frost so intricate it looked like a William Morris print. But how does something as ordinary as ice create patterns so beautifully complex?Hannah and Dara explore this crunchy, slippery, delicately patterned branch of chemistry to uncover the rules and mysteries that govern the extra-ordinary world of ice. Why does ice come in so many shapes and sizes? And does all ice form at 0 degrees Celsius? Is every snowflake truly unique? We have questions a plenty for our eager chemists, who, as all good chemists do, have a few demonstrations up their sleeves to help explain. And we explore nature’s hidden geometry to find why these frost ferns follow the same rules as lightning bolts, river deltas and even human lungs.

Mining for Gold (GOLD!) (00:27:51)
From pharaohs' tombs in Ancient Egypt and medieval currency, to priceless royal jewellery and Spandau Ballet songs - gold has been prized for millennia.
But it's only really in the last century or so that we've started uncovering its usefulness in less decorative applications.Today, gold is used in masses of electricals; it's also revolutionised part of the manufacturing sector by stopping a dangerous reliance on mercury as a catalyst; and it's vital to space missions. Although there are also some more frivolous modern uses for gold, as Hannah and Dara discover. (Gold-leaf in your cocktail, anyone?)Challenged to find out whether all the world's mined gold would really fit in an Olympic swimming pool, our science-savvy duo discover that this antisocial element might just be the best darn thing on the periodic table...

Phantom Pain (00:28:29)
What exactly is 'phantom pain' and how does it work?
Hannah and Dara investigate a medical phenomenon that's been known about for centuries but is often misunderstood; and involves masses of unanswered questions.The condition 'phantom pain' is when someone gets a sensation of pain that feels like it's coming from a part of their body that's no longer there - so that could be an amputated limb, or perhaps something that has been removed, such as a tooth or an organ. It's thought to be caused by how the brain and body process pain and physical awareness, but there's still debate around what exactly is going on neurologically.Researchers around the world are looking into the condition; in the meantime, people who experience phantom pain - like today's studio guest Lynn - often have to try out a range of treatments, to find out what combination works best for them. But as the team discover, pain is deeply subjective - and in this case, there is really no 'right answer'...Contributors:

Tortoise Tomfoolery (00:28:44)
Tortoises have traditionally been the poster child for slowness. These ancient, armoured reptiles are solitary, territorial and all-too-often dismissed as dull.In fact, tortoises have distinct personalities. They have changeable moods, can learn simple tasks, remember certain useful information for years and even recognise familiar people. But can they play?Hot on the trail of tortoise tomfoolery, Hannah and Dara explore the stereotype-smashing studies that show there's far more to these creatures than previously thought; and find out that these complex behaviours might apply not only to the turtle clan, but potentially other reptiles as well...To submit your question to the Curious Cases team, please email: curiouscases@bbc.co.ukContributors:

Planetary Wobble (00:28:28)
Could you survive an eternal winter? Or is endless summer sun a more appealing prospect? Lots of us are grateful for the seasonal changes that shape the world around us, but this week Hannah and Dara are asking what life would look like without the axial tilt that brings each hemisphere closer and further away from the sun as the seasons change each year. Listener Andrew from Melbourne wants to know what would happen if the planet stood perfectly upright, no lean, no tilt, no seasons. But what else could happen? Is Earth’s 23-degree slant the cosmic fluke that made life possible?
To find out, Hannah and explore how losing the tilt reshapes climate, ecosystems, evolution and maybe even the fate of the dinosaurs.You can send your everyday mysteries for the team to investigate to: curiouscases@bbc.co.uk

Immortal Jellies (00:28:52)
Could immortality ever be possible for humans?
It sounds like something from a sci-fi movie, but floating in oceans around the world is a tiny, transparent jellyfish that could hold the answer...Turritopsis dohrnii, known as 'the immortal jellyfish', isn’t immortal in the true sense of word - it can die - but it has a nifty way of avoiding that fate. In times of stress, this miniscule jelly can biologically reverse its aging process, reverting from 'medusa' (adult jellyfish) to a juvenile form and starting its life-cycle again; potentially ad infinitum.Abilities like these could hold the key to - if not exactly 'immortality', then at least regenerative or long-life treatments for humans in future. But of course there's a catch: these extremely delicate jellyfish can still easily die from predation, disease, or environmental threats and are extremely difficult to keep healthy in a lab environment. Hannah and Dara hear about new technology that could change the way we study immortal jellyfish, and discover various other super-abilities in the animal kingdom that could help in our quest for healthier, longer lives.Contributors:

Mysteries from the Final Frontier (00:28:39)
Space: the final frontier, a deep dark realm full of questions and mysteries - many of which science can't yet satisfactorily answer.
But that won't stop the Curious Cases team!In a special edition recorded in front of an audience at the BBC Radio Theatre in London, Hannah Fry and Dara Ó Briain team up with a panel of guests who know their way around the universe: presenters from the world's longest running science TV show, The Sky At Night.With the intergalactic expertise of George Dransfield, Chris Lintott and Maggie Aderin-Pocock, Hannah and Dara tackle a slew of space-related questions put forward by the listeners - exploring topics ranging from the sound of stars and the shape of the universe, to the search for alien life. To submit your question to the Curious Cases team, please email: curiouscases@bbc.co.ukSPACE AUDIO CLIPS:- Maggie's Choice: In 2005, the European Space Agency's Huygens probe descended to the surface of Saturn's moon Titan.

Beam Me Up, Scotty! (00:28:50)
Whether you’re stuck in traffic, waiting at the airport whilst delay after delay is announced or just really missing someone far away, a lot of us have probably wished we could teleport. But is this superpower the stuff of science fiction? Or could it, one day, become a reality?Listener Faith wants to know whether Star Trek’s Transporter could ever deconstruct and reconstruct humans in the real world, and it turns out quantum physics holds some tantalising potential for this seemingly impossible task. To search for answers Hannah and Dara dive down the quantum rabbit hole, exploring entanglement, superposition, and trying on some very special socks. Contributors

Going Viral (00:28:35)
Cold and flu season is well and truly upon us, and whilst most of us are busy bemoaning the pesky viruses behind our sniffles and chesty coughs – one of our listeners has other ideas. Elizabeth wants to know whether we’re too hard on these oft-maligned microbes? We’ve all heard that some bacteria can be good for us, but what about viruses? Could they have a softer side too?
Hannah and Dara explore the virome, from prehistoric placental proteins to ultra-precise disease fighting phages to find out if Viruses truly are the villains of the microscopic world or whether they just need a better PR team. Contributors

We Didn't Start the Fire (00:28:33)
It has been said that you can't start a fire without a spark, but as Hannah and Dara are about to discover, that's not true!Welcome to the fiery phenomenon of spontaneous combustion, when something can ignite all on its own: no matches, no sparks, no external flame. It happens when certain materials heat themselves up internally through chemical or biological reactions, and if that carried on unchecked and the material gets hot enough, it can eventually ignite itself.This process can occur in various everyday items such as piles of hay or grass clippings, oily rags and in certain instances lithium batteries; but there are also several useful chemical substances that autoignite when they come into contact with air - as Hannah, Dara and a wary BBC fire officer witness in the studio...So how can we stop things regularly bursting into flames? How scared should we be about oiling floorboards and our increasingly battery-powered life? And is spontaneous human combustion really a thing? Our investigators are on the case.

Are you a lucky person? Do the cards just fall well for you? Whether it's always finding a parking spot when you need one or chance encounters that change your life's trajectory for the better, some people seem to have more luck than others.

Good Vibrations? (00:28:34)
It turns out that the whole world wobbles. Everything has a natural frequency - the rate at which it moves when disturbed - be it a cup of tea, a building or a human organ.Even more incredibly, if an external force matches an object's natural frequency, it causes it to absorb that energy and vibrate with increasingly large waves; and that can have consequences, from helping a spider find its lunch to making a bridge collapse. On the trail of good and bad vibes and everything in between, Hannah and Dara investigate whether the famous 1940 collapse of the Tacoma Narrows Bridge in the USA was really down to resonance, explore examples of resonance in nature, and find out what this mysterious vibration can do to the human body: from the pressures of repetitive tractor-driving, to absorbing the reverberations of certain instruments...To submit your question to the Curious Cases team, please email: curiouscases@bbc.co.ukContributors:

To Crab, or Not to Crab? (00:29:02)
We can all picture a crab, but did you know that nature has reinvented those claw clicking, sideways scuttling crustaceans at least five separate times? In recent years the internet has run wild with the idea that crabs are the ultimate life-form, and that even humans might one day end up with pincers too. But is there any truth behind the memes? Hannah and Dara scale the tangled tree of life and tackle taxonomy to figure out if ‘crab’ really is evolution’s favourite shape. Exploring coconut to spanner, ghost to hermit, soldier to spider they learn how to tell the ‘true’ crabs from the impostors.You can send your everyday mysteries for the team to investigate to: curiouscases@bbc.co.uk Contributors

Trailer (00:02:10)
Hannah Fry and Dara Ó Briain return to Curious Cases HQ for a brand-new series. And curios, there’s a lot to unpack! Coming soon to BBC Sounds.
Clever Crows (00:28:30)
The term 'bird brain' might suggest our feathered friends are stupid, but Hannah and Dara learn it's completely untrue. They play hide and seek with a raven called Bran, and hear how his behaviour changes depending on his mood. Corvid expert Nicola Clayton explains these creatures are actually cleverer than the average 8-year-old, and can learn how to choose specific tools for different scenarios. And neurobiologist Andreas Nieder tells them that while crows evolved totally different brains from humans - 300,000 years apart - they might just be capable of the same type of intelligence.

Memory Swap (00:30:19)
Could you ever trade memories with someone else? Fancy downloading the experience of landing on the moon, winning an Oscar or performing at Glastonbury? Listener Adam wants to know, and Hannah Fry and Dara Ó Briain are on the case.With expert insights from Professor Chris French and Professor Amy Milton, they dive into the mind’s tendency to blur the lines between reality and imagination - often embellishing, distorting, or downright making stuff up.Discover how memory conformity makes us “see” things like spoons being bent by paranormal forces, how scientists can implant artificial memories in mice, and hear Al Hopwood’s hilariously vivid tales of things that definitely never happened. Chris even spills the secrets of how to deliberately plant false memories in others (don’t try this at home!).From rewiring trauma to curing phobias, the potential of memory manipulation is both exciting and unnervingly sci-fi.

It sounds bananas, but it’s all part of Einstein’s mind-warping theory of relativity.With expert copilots Professor Sean Carroll and Dr. Katie Clough, Hannah Fry and Dara Ó Briain embark on a cosmic roller coaster through space and time. They uncover why GPS satellites - whizzing around Earth at 14,000 km/h - need to account for time bending, why penthouse dwellers age faster than those on the ground floor, and, most importantly, why clowns on trains might just hold the key to understanding modern physics.Contributors:Katy Clough - Research Fellow at Queen Mary University of London

Colossal Creatures (00:28:57)
How big can animals really get before they collapse under their own weight or run out of snacks? Could a 12-foot comedian survive their first punchline without snapping in half? Listener Andrew sends Hannah and Dara on a deep dive into the science of supersized species.With evolutionary biologists Ben Garrod and Tori Herridge as their guides, they explore the quirky rules of scaling: why giant bones need air pockets, how pressure stockings aren’t just stylish but essential, and why massive creatures have to choose between inefficient chewing or letting dinner ferment in their cavernous stomachs.Discover why scaling up a mouse would turn it into a blood-boiling disaster and learn the curious logic behind whether the meat bear should eat the two meat dogs, or vice versa (it’s a maths thing…you’ll have to listen). Oh, and here’s the weird constant: whether you’re a mouse or an elephant, everyone takes roughly the same time to pee!Join Hannah and Dara for a colossal romp through the wild world of ancient giants and the gross super blobs of the (possible) future.

Nano Sharks (00:29:17)
Think of a shark and you'll probably conjure up images of Jaws, but it turns out their skin is also covered in tiny teeth. Hannah and Dara investigate the incredible properties of these so-called dermal denticles, to find out whether they could be replicated at a nanoscale to increase vehicle speeds. They learn that while sharks might look like they have beautifully sleek surfaces, up close their skin is covered in something extremely rough and textured, a property that helps them swim up to 12 percent faster. And it's already inspiring airlines to design ultra-thin films that can reduce drag and increase efficiency.ContributorsDr Jess Wade

Why do we giggle, snort, and bust a gut laughing? Is it just humans being weird, does it serve some higher function or do other animals crack up too? And, okay, Dara is a comedian, but has he ever really made anyone laugh, like properly? With help from Professor Greg Bryant and Professor Sophie Scott, they dive into the science of LOLs, exploring how laughter bonds us, eases stress, and even spices up flirting.

Hannah and Dara grapple with the question of whether these insects are evil or genius, discovering how they’re experts at finding blood when they’re hungry, even using a specially designed syringe to suck it out. But when Professor Leslie Vosshall tells them some people are more than 100 times likely to be attacked than others, the pair start wondering which one of them is more attractive? So they put the science to the test, and reluctantly agree to send their stinky socks to Professor Sarah Reece.

The team test the theory that you can use the weather to predict pain, separating science fact from fiction. It's an area with a huge amount of conflicting research, but one man who has investigated this is Professor Will Dixon, who explains that low pressure could be causing people's joints to ache more. Dara and Hannah are intrigued to hear our genes may also be responding to changes in temperature and hear how we might be pre-programmed to produce more inflammation during wintertime to fight off bugs - which has the unfortunate side effect of making other some conditions worse. But don't despair! The pair find out 21 degrees is the optimum temperature for health and wellbeing - a perfect English summer day.Contributors:Dr Chris Wallace

Furnishing with Fungi (00:28:35)
From mouldy bread to athlete’s foot, fungi don’t exactly scream “home improvement.” But what if this misunderstood kingdom is the secret to the sustainable materials of the future?Listener Alexis - definitely not a gnome - wants to know how much of our homes we could build with fungi. Professor Katie Field describes how the mushroom is the just tip of the iceberg - it’s the network of thread-like filaments called mycelium where fungi really do their best work. Architect Phil Ayers explains how fungi, like yeast in bread, can bind waste products into firm, MDF-like blocks. And while we’re not constructing skyscrapers with mushrooms just yet, it turns out fungi-based materials are already making waves in interior design. Think sound-absorbing wall panels or insulation that’s both eco-friendly and chic.And here’s a cool one: mushroom leather! Using discarded stalks from mushroom farms, one company is crafting strong, flexible material for trainers, handbags, and even car dashboards. Move over, cows - mushrooms are pushing their way up.Oh, and NASA? They’re dreaming big with fungi too - to grow habitats in space. From mould...to the moon!

Love Neurons (00:28:37)
What happens in your brain when Cupid’s arrow strikes? As a teenager, Alison developed an intense crush on George Harrison from the Beatles. But, she wants to know, why do we develop these feelings for pop stars we’ve never actually met? And what potent swirl of neurochemistry drives those fierce emotions?With neuroscientist Dr. Dean Burnett and evolutionary anthropologist Dr. Anna Machin as their guides, Hannah and Dara investigate everything from the brain’s chemical fireworks during a crush to the evolutionary perks of love and bonding. Along the way, they dissect teenage infatuations, lifelong love affairs with football teams, and why love can feel as addictive as heroin.There’s even a guest appearance from two cute rodents: the monogamous prairie voles and their more, shall we say, commitment-phobic cousins, the montane voles, who gave us early clues about the role of the ‘cuddle’ hormone oxytocin. Whether you're a hopeless romantic or a hard-nosed skeptic, prepare to fall head over heels for the science of love.Contributors:Dr Anna Machin - evolutionary anthropologist and author of Why We Love

Invisibility Quest (00:29:36)
Hannah and Dara tackle a disarmingly simple question: is anything in the universe truly invisible? After ruling out mysterious Nordic spirits and ‘Dara’s ire’, our curious duo start to track down the invisible waves all around them. Including, it turns out, some which are emanating from their VERY OWN FACES! An infrared camera reveals Hannah’s nose as a particular hotspot.Turning their gaze to bigger things, they wonder: what does our own galaxy look like when viewed in this invisible spectrum? Infrared reveals vast loops and whorls of dust and gas - gigantic structures otherwise totally hidden. But there are even cooler surprises. Ever wondered what an X-ray of the universe looks like? Turns out it’s a sparkly map of white-hot black holes! Back on earth, the discussion turns to ways of making objects disappear by bending light in tricksy ways. But why is the fancy science of ‘metamaterials’ still struggling to make a proper invisibility cloak? Sorry, Harry Potter fans.In the end, our physicists reveal a universe bursting with even more elusive, even more mysterious stuff: dark matter and dark energy.
