What happened to the birds in 'The Twelve Days of Christmas'?

We all know it. We've all sung it. Perhaps we've even answered a quiz question about it*. The Twelve Days of Christmas has become as quintessentially festive as a figgy pudding, or the bad joke in your Christmas cracker. But why exactly is your 'true love' gifting all these birds? And importantly, how are they faring nowadays? Prof Andy Gosler (from the Edward Grey Institute in the Department of Biology, and Institute of Human Sciences in the School of Anthropology) is the only professor of 'ethno-ornithology' in the world, specialising in the study of the relationships between birds and people. So, who better to be our guest on this festive edition of the Big Questions Podcast, where we take a deep dive into one of our favourite Christmas carols? (*There are 364 presents in total, by the way!)

What is quantum computing?

Want to make something feel immediately complicated, inaccessible or downright mysterious? Stick the word 'quantum' in front of it. Or, at least, that's how many of us feel. But don't worry! Experimental physicist William Cutler from Oxford's Department of Physics is here to break things down, explaining exactly what a quantum computer is, and sharing the remarkable potential that quantum computing holds for advancing fields ranging from drug-discovery to internet security.

Could vaccinations stop people from getting cancer?

Finding a cure for cancer is unarguably one of the biggest medical challenges that we face. But what if we could find a way to prevent cancer before it even starts? In this special extended edition of the Big Questions Podcast, we chat to Professor Sarah Blagden, an experimental oncologist at the University of Oxford, and Anna Fry, who has the cancer predisposing condition Lynch Syndrome - putting her at increased risk of developing colorectal and other cancers. Sarah explains how clinical trials of vaccines targeting 'pre-cancer' could revolutionise the fight against cancer, beginning with those at greatest risk.

Why do I bite my nails?

Many of us will be familiar with Body-Focused Repetitive Behaviours (BFRBs), perhaps without even realising it. Such behaviours - which include hair-pulling, nail biting and skin picking - can not only cause physical harm, but also often bring feelings of shame. Because of this, open discussion around BFRBs has been limited. In this episode of The Big Questions Podcast, we chat to Prof Clare Mackay from Oxford's Department of Psychiatry, who both studies and lives with BFRBs.

How do you find a theoretical particle?

How do you detect a particle that emits no light - in other words, something invisible? This is the intriguing challenge faced by scientists hunting for 'dark matter'. In our series finale, we talk to Elizabeth Bloomfield from Oxford's Department of Physics about dark matter, how we know it exists, and why her research is taking her deep beneath a mountain in Italy in the quest to find it.

Is there a better way to screen blood?

What's the best gift you can give? To the millions of people whose lives have been saved by complete strangers, the answer would be simple: blood. But what exactly happens when blood has been donated, and how do we know it is safe? We chat to Dr Richard Mayne from Oxford's Experimental Medicine Division about genomics, Next-Generation Sequencing, blood screening (...and Star Trek). Could you be a blood-donating hero? Blood stocks are currently critically low, with the NHS Blood and Transplant (NHSBT) group in urgent need of new donors.

How does Ozempic actually work?

Whether you've been served an advert for it, or just heard about it in the media, it's likely that 'Ozempic' isn't a totally unfamiliar word. Now often associated with weight-loss, Ozempic is actually the brand name for a drug used to treat diabetes. So what exactly is it, how does it work, and is it safe? We chat to diabetes and endocrinology (hormone) expert Dr Annie de Bray to find out.

Why does a stranger's phone noise annoy me?

We've all been there...you're on the train, maybe tired after a long day, and all you can hear is one side of a fellow passenger's not-too-interesting phone conversation. Or worse, their choice of music, made tinny and monotonous by the awkward angle of their phone speaker. It's irritating, sure, but for some people it goes beyond mild annoyance, into the realms of anger and panic. For these people - who suffer from a condition called 'misophonia' - phone noise, or sounds such as chewing or breathing, are a real problem. We chat to Dr Jane Gregory, a researcher at Oxford's Department of Experimental Psychology who has misophonia, to find out more about this little-known condition.
