Tessellation Proliferation
We may think of tessellation as being about how to tile a flat plane but this week we reveal how repeating patterns actually occur all over the place, and can even help us solve some of nature's most complex problems.The presenters start with the simple principal that for shapes to fill a space without leaving any gaps or overlapping, the angles in the corners have to add up to exactly 360° - which means squares, triangles and hexagons are all strong contenders. Then they try their hand at creating their own tiles, based on a technique referred to as the 'Escher' method.If you have an everyday mystery for the team to investigate, contact them on curiouscases@bbc.co.uk.Contributors:Dr Katie Steckles Prof Mark Miodownik Dr Vince GalloProducer: Lucy Taylor Executive Producer: Sasha Feachem A BBC Studios Production

Yawn Chorus
We often associate yawning with being tired or bored - but this week's episode explores whether it could be a clever way to cool down our brains?Hannah and Dara discover humans aren't the only species that yawn. From cats to chimpanzees and even fish, plenty of other vertebrates engage in this ancient behaviour which scientists believe evolved hundreds of millions of years ago. And it doesn't always happen as a spontaneous reflex to feeling tired but can also be triggered by watching other people do it.If you have an everyday mystery for the team to investigate, contact them on curiouscases@bbc.co.ukContributors:Stephen Jackson - Professor of Cognitive Neuroscience, University of Nottingham Laura Kelley - Associate Professor in Behavioural Ecology at University of ExeterDr Andrew Gallup - Professor of Behavioral Biology at Johns Hopkins UniversityProducer: Lucy Taylor Executive Producer: Sasha Feachem A BBC Studios Production

Making Waves
What happens when you give water a really good shake? You might expect splashing, spilling and general aquatic chaos - but under exactly the right conditions, something much stranger can happen... In this episode, Hannah Fry and Dara Ó Briain dive into the world of 'Faraday waves': amazing geometric patterns that, in certain circumstances, will appear on the surface of a vibrating liquid. They discover how the renowned physicist Michael Faraday accidentally discovered this remarkable phenomenon in the 19th Century; debate whether they could ever occur in a swimming pool; and find out what on earth alligators have to do with it. Along the way, the pair encounter eerie ‘square’ seas and learn about new ways satellites are helping us to understand the ocean’s wildest waves!If you have an everyday mystery for the team to investigate, contact them on curiouscases@bbc.co.uk.Contributors: Cédric Beaume - Associate Professor in Applied Mathematics at the University of Leeds Lucy Bricheno - Group Head of Coastal Ocean at Liverpool’s National Oceanography Centre Glynn Holt - Former Professor of Mechanical Engineering at Boston UniversityProducer: Lucy Taylor Executive Producer: Sasha Feachem A BBC Studios Production

Identical(ish)
Ever wondered how close nature can get to making a human clone? And what happens if identical twin brothers marry identical twin sisters and have babies - how similar are they? Our listener Chris has been pondering this very issue, and his question takes Hannah and Dara down another scientific rabbit hole.Our intrepid duo consider how one fertilised egg can somehow become two babies, why those babies aren’t quite genetic photocopies, and why even identical twins gradually become more different as they grow up. They also find out how studying twins is helping scientists learn lessons about how all of us age - and explore the classic, movie-perpetuated mystery of “twin telepathy”… could there maybe, possibly, be something to it?! There’s also just time to address the tricky issue of cloning. From Dolly the sheep to regenerative medicine, cloning science has paved the way for some serious breakthroughs; but could we ever clone a human? And more to the point, should we?Expect sheep, sci-fi, identical cousins, and a dash of disproven twin mythology, as Curious Cases makes its return!If you have an everyday mystery for the team to investigate, contact them on curiouscases@bbc.co.uk.Contributors: Xand van Tulleken - Doctor, broadcaster and Honorary Associate Professor of Infection and Population Health at University College London Kevin Sinclair - Professor of Developmental Biology and Head of Animal Sciences at the University of Nottingham Claire Steves - Principal Investigator at TwinsUK and Professor of Ageing and Health at King’s College London Chris van Tulleken - Doctor, broadcaster and Professor of Infection and Global Health at University College LondonProducer: Lucy Taylor Executive Producer: Sasha Feachem A BBC Studios Production

Frosty Fractals
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!)
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
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: - Tamar Makin, Professor of Cognitive Neuroscience at the MRC Cognition and Brain Sciences Unit at the University of Cambridge, where she leads the Plasticity Lab; - Lynn Williams, a qualified therapist and upper limb amputee who volunteered as a subject for one of Tamar’s research programmes; - Carlos Roldan, Associate Professor in the Department of Pain Medicine at the University of Texas MD Anderson Cancer Center; - Keren Fisher, a Consultant Clinical Psychologist who’s worked in the NHS for more than four decades; largely in pain management at the Royal National Orthopaedic Hospital.Producers: Emily Bird & Lucy Taylor Executive Producer: Alexandra FeachemA BBC Studios Audio Production
