Oxford Sparks Big Questions

Each of us is different. Our genetics and life experiences shape us into unique individuals – with unique brains. When it comes to medicine, therefore, a 'one size fits all' approach is often not adequate, and trial and error is required to find the best treatment for a condition: especially when it comes to the brain. But what if a doctor could rely on personalised recommendations about what course of action may be best for a specific patient? We chat to computational neuroscientist Dr Andrea Luppi from Oxford's Department of Psychiatry about 'digital brain twins', and how - when it comes to brain conditions - they could help to achieve just that.

Put simply, most drugs work by binding to a protein and altering how they function. But how can we model how well a particular molecule will bind to a particular protein, and use that knowledge to help discover new treatments? In this episode, we talk to Prof Fergus Imrie from Oxford's Department of Statistics, who is one of the lead researchers on the OpenBind consortium. This project aims to create the world's largest open-access dataset of protein-ligand interactions, providing invaluable quantities of data for AI-driven drug discovery

In 2022, 7% of the UK's total carbon emissions came from the aviation sector - a figure that's on the rise. This means that - while a flight is often the start of a well-deserved holiday - a lot of us feel at least a sprinkling of guilt over our carbon footprint. So, what if we could reduce the carbon emissions associated with air travel? In this episode, we chat to Dr Tamsin Whitfield from Oxford's Department of Materials Science, and hear about her research developing new metals, which will ultimately allow jet engines to burn hotter, increasing their efficiency.

Until recently, most of us had probably never even heard of the hantavirus. Now - with memories of the global COVID-19 pandemic still fresh in our minds - it's only natural to feel slightly concerned about the new virus hitting our headlines. But are our worries justified? We chat to Dr Daniel Wright from the Oxford Vaccine Group, who develops vaccines against emerging outbreak viruses, to learn more about hantaviruses, and what they really mean for public health.

'Killing animals' and 'conservation' sound mutually exclusive, but when it comes to managing populations that are having a negative environmental impact, is culling the answer? If so, how do people feel about it? We chat to Jessica Frater from the Department of Biology at the University of Oxford about Scotland's deer cull, exploring why human perceptions are often at the heart of conservation challenges, and how gaining deeper insight to these perspectives can support more conservation efforts.

"It's as likely as winning the lottery." A phrase used in situations where something is, well, pretty near impossible. But is there anything you can do to increase your chances of claiming that life-changing pot of money? What about one of the smaller prizes? We chat to applied mathematician Dr James Munro about probability, chaos theory and whether anyone could ever predict the lottery.

Aside from the odd unfamiliar or complicated word, a lot of us won't think twice when it comes to reading. It's a skill we take for granted. But, relatively speaking, it's actually a fairly new skill - beginning about 5500 years ago. This suggests it's not something we evolved to do, so, how does it work? We chat to Prof Ole Jensen from Oxford's Departments of Experimental Psychology and Psychiatry, who is trying to gain a better understanding of the neural processes behind reading, with the ultimate aim of helping those who are struggling to learn.

Historically, only two women have ever started a Grand Prix race, and as of the 2026 season, no women are competing in Formula One. This male dominancy is by no means restricted to the track, with social scientist Dr Kate Bancroft estimating that a mere 5% of technical motorsport roles (that is, the engineers and mechanics) are taken by women. We hear from Kate about her research into the F1 gender gap, which she hopes - alongside revealing some of the barriers and struggles faced by women - will start a wider conversation about the divide that exists in top-level motorsports. **During the podcast, it was mentioned that there has not yet been a female team principal in Formula 1. We would like to clarify that Monisha Kaltenborn served as Team Principal for Sauber from 2012 to 2017 (the first woman to hold the role).**

We're living in an age of rapid technological development which - alongside many benefits - comes at an environmental cost. We speak to Dr Shurui Miao, an experimental chemist who aims to decouple technological advancement from the impacts of increased carbon emissions, by finding a way to safely store carbon underground. As he explains, by finding a way to convert CO2 from the atmosphere into minerals, we could store carbon securely and sustainably into the future, and ultimately begin to mitigate the effects of climate change.

This week we are featuring a special bonus episode from our friends at the Milk on the Move podcast. Milk on the Move explores milk's deep cultural roots, evolving scientific narratives and the systems that shape its production today. Hosts Johanna Zetterstrom-Sharp and JC Niala uncover the fascinating interaction of tradition, knowledge and morality that makes milk so much more than just an everyday drink. Available on Apple Podcast, Spotify or head to milkingit.org for more information.

If you've had the chance to visit Oxford's History of Science Museum, you may have found yourself gazing upon a rather special blackboard. Featuring equations that connect the age, size and density of the Universe, the penmanship is that of Albert Einstein himself, who used the blackboard during a lecture on 16th May 1931. But what was Einstein doing in Oxford, and how did he spend his time there? We chat to Dr JC Niala, Head of Research, Teaching and Collections at the History of Science Museum, to find out more about the man (and musician!) behind the genius. Dr JC Niala also hosts her own brilliant podcast, alongside Dr Johanna Zetterstrom-Sharp, called 'Milk on the Move'. You can listen to an episode ('Purity and Danger') right here on our playlist, or find out more at milkingit.org .

For this year's Valentine's Day episode, we are getting up close and personal with those most beloved of birds - penguins. Giving us an insight into the love lives of our feathered friends are penguinologists (yes, that's a real word) Dr Ignacio Juarez Martinez and Dr Fiona Suttle, who have both graduated from Oxford's Department of Biology, and spent multiple field seasons in Antarctica monitoring penguin breeding behaviour. We hear how penguin breeding patterns appear to be shifting with changing temperatures, and how you can get involved in their research - just head to Penguin Watch to take part.

How much more money could you earn - doing the exact same role - if you're in possession of some solid AI skills? That's one of the core questions that Dr Fabian Stephany, a researcher at the Oxford Internet Institute, hopes to answer. Leading the 'SkillScale' project, Fabian looks into the impact of AI tools on the labour market, with the ultimate hope of advising workers on the best ways to secure jobs and increase their salaries. So, far from a discussion about 'AI stealing our jobs', we ask Fabian - how can we use AI to secure a bigger pay packet? Find out more: Skills or Degree?

Are we alone in the Universe? It's surely one of the biggest questions out there. In our first episode of 2026 we chat to Dr Carly Howett, Associate Professor of Space Instrumentation in Oxford's Department of Physics. Specialising in the study of the 'icy worlds' found in our outer Solar System, Carly explains why she thinks one of Saturn's moons, Enceladus, could be a prime candidate for life, and shares the latest updates on how we might find it.

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!)

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.

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.

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 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.

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.
