# Curious Cases Hannah Fry and Dara Ó Briain tackle listeners' conundrums with the power of science! Page: Feed: --- ## [Frosty Fractals](http://www.bbc.co.uk/programmes/m002nv73) _2026-01-02_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mrn3br.mp3) ## [Mining for Gold (GOLD!)](http://www.bbc.co.uk/programmes/m002ntwk) _2025-12-31_ From pharaohs' tombs in Ancient Egypt and medieval currency, to priceless royal jewellery and Spandau Ballet songs - gold has been prized for millennia.

Today, gold is used in masses of electricals; it's also revolutionised part of the manufacturing sector by stopping a… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mrgsqz.mp3) ## [Phantom Pain](http://www.bbc.co.uk/programmes/m002nh61) _2025-12-19_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mpfm31.mp3) ## [Tortoise Tomfoolery](http://www.bbc.co.uk/programmes/m002n7mf) _2025-12-12_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mmzgwc.mp3) ## [Planetary Wobble](http://www.bbc.co.uk/programmes/m002myr1) _2025-12-05_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mljn5l.mp3) ## [Immortal Jellies](http://www.bbc.co.uk/programmes/m002mmj2) _2025-11-28_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mhsmd5.mp3) ## [Mysteries from the Final Frontier](http://www.bbc.co.uk/programmes/m002m8zz) _2025-11-21_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mhskz3.mp3) ## [Beam Me Up, Scotty!](http://www.bbc.co.uk/programmes/m002lzkc) _2025-11-14_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mgg6ms.mp3) ## [Going Viral](http://www.bbc.co.uk/programmes/m002lpfc) _2025-11-07_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mf5slp.mp3) ## [Daily plans, scheduled by AI (Sponsored)](https://crawlproof.com/a/0NmeqyZVAwZi) _2025-11-07 · **Sponsored**_ AI-made daily plans that schedule tasks and protect focus time. ## [We Didn't Start the Fire](http://www.bbc.co.uk/programmes/m002ldh6) _2025-10-31_ 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… [Listen](http://open.live.bbc.co.uk/mediaselector/6/redir/version/2.0/mediaset/audio-nondrm-download-rss/proto/http/vpid/p0mcrf5k.mp3)
