Oxford Sparks Big Questions
Oxford Sparks Big Questions is a science podcast that tackles curious and sometimes surprising questions, such as whether bacon sandwiches are unhealthy, the risks of vaping compared to smoking, and how one becomes an astronaut. Each episode features conversations with leading scientists from Oxford, exploring a different area of research in an accessible and engaging way. The show aims to bring the excitement of Oxford science to a broad audience.
Episodes
What is a digital brain twin?
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 cou
How can we use AI to make drugs?
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 cr
How do you build the aeroplane of the future?
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
Should I be freaked out by the hantavirus?
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 m
Should we kill animals for conservation?
'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 ch
Can you predict the lottery?
"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.
How does reading work?
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 Psychiatr
What's it like for women working in F1?
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 gende
How do you convert CO2 to rock?
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 min
From the Milk on the Move podcast: Purity and Danger
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 every
What was Einstein doing in Oxford?
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?
Where do baby penguins come from?
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 monitorin
How can I use AI to raise my salary?
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 secu
Could stuff be living on Saturn's moon?
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, a
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 B
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 computin
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
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 Macka
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
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 peopl
What's the origin of water on Earth?
With more than 70% of its surface covered in water, Earth is rightly known as the "blue planet". But where did this water - so essential to life - originate? While some theories suggest that hydrogen was delivered to Earth from space via asteroids, new research indicates that the building blocks for water may have been present on our planet all along. We chat to Tom Barrett from Oxford's Departmen
How can robots investigate underwater volcanoes?
What do you do when the subject of your research lies deep beneath the waves? Send down an underwater robot, of course! We chat to volcanologist Sofia Della Sala about her recent fieldwork expedition to Santorini, where she used a Remotely Operated Vehicle, or ROV, to search for hydrothermal vents in the Aegean Sea. These vents - which are like hot springs on the sea floor - could provide vital in
What is it like to be on Countdown?
"I still don't believe it happened..." What's it like to face the most famous clock on television? We chat to Oxford mathematician Dr Tom Crawford - best known as the creator of the award-winning 'Tom Rocks Maths' outreach programme - about what it was like to step into Rachel Riley's shoes on Countdown. What's the best tactic for tackling the numbers round? How did he prepare? Did he really only
What happens after a dementia diagnosis?
One in two people will be affected by dementia in their lifetime - whether that is as a patient, or somebody caring for a loved one. But what happens after a dementia diagnosis? Is there a clear pathway ahead? We chat to Jasmine Blane, a DPhil researcher at the Oxford Brain Health Clinic, about the work she is doing to help support patients in the midst of a dementia diagnosis, and into the future
Is it OK to laugh at Tourette's?
In popular culture, Tourette's syndrome is wrongly associated solely with outbursts of swearing in the context of lazy jokes. But in reality, the condition is far more complex than this stereotype suggests. When people without Tourette's jokingly blame their lack of self-control on the condition, it spreads misinformation and invalidates those who actually live with it. Despite this, comedy - when
What is a dinosaur highway?
If you were hunting for some fossilised dinosaur footprints, where would you go? To a remote part of North or South America, perhaps? A deserted wilderness for sure... But how about Oxfordshire? We chat to Dr Duncan Murdock from the Oxford University Museum of Natural History about an incredible discovery made right on our doorstep. Photo © Dr Emma Nicholls / Oxford University Museum of Natural Hi
How horny are hedgehogs?
Shh...hedgehog! It always feels like a privilege to catch a glimpse of one, as it snuffles away under the garden fence. And come the spring, our spiny - and usually solitary - little friends will be feeling in the mood for...romance. But what exactly does a female look for in a mate? And how do their intimate encounters even work when things are so very... spiky? Join us for this special Valentine
What can batteries of the future learn from eels?
Electric eels are pretty amazing creatures. Their bodies can release powerful electric charges - in some cases reaching 650 volts! So, what can scientists learn from these animals? Could nature hold the key to advancing our own energy solutions? We chat to Dr Yujia Zhang about how electric eels might inspire the batteries of the future.
Why is my bottle cap attached to my plastic bottle?
Whether it's the bottle of water that you hastily grab at the train station, or your favourite guilty-pleasure fizzy pop, you may have noticed something different about your drinks lately - or at least their containers. Since July 2024, it's been EU law that bottle caps are attached, or 'tethered', on all single-use plastic bottles. But what exactly is the reason for this change? Will it really he
Why are we seeing the Northern Lights more often?
Even if you'd never previously given much thought to the Northern Lights, chances are they were brought to your attention in 2024, when our social media feeds were set ablaze with beautiful images captured by awe-struck stargazers. Usually restricted to more northerly latitudes, this colourful natural phenomenon could be observed in the UK as far south as Cornwall. But why were we treated to this
Why track mistletoe?
Mistletoe has long been associated with fertility, and even today, its presence hanging from the ceiling can prompt a few blushes. But, did you know, mistletoe is more than something beneath which to kiss at Christmas? It is actually a parasite, and has some rather peculiar biology behind it. We chat to mistletoe expert Ollie Spacey about what makes it so special, where you can spot it and - impor
Why are birth rates falling in the UK?
Evolutionarily speaking, it makes sense to have a lot of children. At the very least, we might expect a population to replace itself, with each couple having an average of two children. However, this evolutionary logic is not mirrored by current data: birth rates are falling in the UK, with many people choosing to either have one child, or no children at all. We speak to evolutionary anthropologis
What is a wind drought?
Chances are, you didn't notice the week-long wind drought that the UK experienced towards the end of 2023. However, this period of low wind speeds, combined with a cold snap, drove up our energy prices - something that may have caught your attention. So, what exactly do we know about wind droughts, and how can we apply this knowledge to plan for the low-carbon energy systems of the future? We chat
How do you sequence the genomes of 70,000 species?
Welcome back to the new series of the Oxford Sparks Big Questions Podcast! We are here to answer weird and wonderful questions about our world, with the help of science. And we're starting with a very big question! How do you sequence the genomes of 70,000 species? Dr Liam Crowley, from the Department of Biology, tells us about the ground-breaking Darwin Tree of Life project, which aims to seque
How do I keep my house cool without air conditioning?
Summer is here, and with heatwaves forecast, how do we keep our homes cool without relying on air conditioning? In the UK, soaring summer temperatures can be brief but powerful. So, what can we do? Nicole Miranda, from the Department of Engineering, shares practical, energy-efficient and eco-friendly strategies to help you stay comfortable during the hot months. And yes, ice creams are encourage
What time is it on the moon?
Scientists are returning to the moon, but when they get there, what time is it? Dr Carly Howett from the Department of Physics explains the basics: what time is, and how we found a globalised way of understanding time zones so we can meet for a 3pm coffee or international video call, and everyone is in the right place at the right time. But how does that translate to space and why could the conseq
How can origami help make energy?
Discover how the ancient art of origami is revolutionising sustainable energy! Researcher Jingyi Yang, from the Department of Engineering Science, has loved origami since childhood. Now she's channelling that passion to tackle engineering challenges. Using the intricate papercraft to develop clam-like models, Jinyi's creative engineering may be the key to improving the efficiency of energy produce
How do you fossilise a brain?
When you think of fossils, you probably imagine dinosaurs. But did you know that soft body parts, like the brain, can become fossils too? In this episode, forensic anthropologist Alexandra Morton-Hayward explores the science of brain fossilisation. Skeletons have been found in wells, Incan temples, salt mines and many other unusual locations, often with no other organs, hair or skin preserved. Wi
How do earworms work?
Have you ever had a song stuck in your head that you just can't shake? A few bars or lyrics that just keep looping all day long? Well, we have delved into the science behind 'earworms' with Dr Jacob Kingsbury Downs from the Faculty of Music. A melodic mix of musical imagery, auditory neuroscience, memory and impressive compositions can leave a little ditty echoing in our minds long after the last
How are seals affecting fishing catches?
Are seals the fishermen's friends or foes? The UK is home 35% of the world's grey seals and we know they like to get their flippers on many of the same fish as we do. So, how are seals impacting the fishing industry? In our latest podcast, Dr Claire Tanner from the Department of Biology explores the unseen conflict beneath the waves and the complex dynamics between these marine mammals and fisheri
Why am I killing my house plants?
House plants can be a cheerful pop of colour in your home. But do you find after the initial burst of life, your plants start to fade, looking sad and unhealthy? M Garrido Davies, from the Department of Biology, shares top tips for helping house plants to flourish, starting with learning more about the biology of how plants grow in their natural environment. Did you know that when you add too
How are volcanoes formed on other planets?
Volcanoes are pretty amazing! But how do they work on other planets? Take Mars – it has the largest volcano in the solar system! But volcanologist Tamsin Mather reveals that the red planet is now considered geologically dead, with no volcanic activity for around 500 million years. How do we know how this volcano formed then? Well, space missions have put probes and landers on Mars' surface, prov
Can we talk to bees?
We are out in the wild today talking to bees! In this behind the scenes episode, we visited Dr Rachel Parkinson's bee recording studio to see insect neuroscience research in action. You might know that honeybees communicate with each other using the waggle dance, a minute choreography that shows other bees the way to the flower buffet. But little is known about how bumblebees communicate. T
Why are people obsessed with how cute cats are?
Cats are pretty adorable! Those big eyes, fluffy paws and cheeky personalities mean that most people find felines cute. But what is the science behind this reaction? Neuroscientist Professor Morten Kringelbach reveals how special technology can track what happens to signals in the brain in response to sounds and images of babies and small animals. In just a thousandth of a second, our brain decide
How freaked out should I be about bed bugs?
You might have seen them in a hotel. You might have read about them in the news. Maybe you've seen them star in social media videos filmed on the London underground. But should we really be worried about bed bugs? The little critters evolved from feeding on bats and birds to humans thousands of years ago and were part of society for hundreds of years. But with the invention of synthetic pesticid
When did we start kissing?
Have you ever considered when kissing first started? Who, or what, first decided that this was a good way to show affection? Ancient historian, Troels Pank Arbøll, and hedgehog researcher, Sophie Lund Rasmussen, joined forces to attempt to find an answer. Cuneiform scripts, which are the world's oldest written text, have the first mention of romantic kissing in a mythological narrative dating
How do you stay warm in your house without central heating?
How do we battle the energy use and soaring costs required to keep our homes warm? We spoke to Dr Brenda Boardman from the Environmental Change Institute about the best ways to keep out the winter chill. Did you know that draughts not only let cold air in, but they also push the warm out of your home? And that sitting or sleeping next to external walls can make you colder? Discover simple and inex
How will climate change affect wine?
People have been interested in wine growing and quality vintages since the Roman times, but as the climate warms, what does this mean for the future of wine growers in the UK (and beyond)? Andrew Wood, from the Department of Biology, has been studying the records of wine critics, which reveal much more than whether the bottle is a good vintage or not. The vintage can tell scientists what the gro
What are the odds of a white Christmas?
As we count down to the festive season and the days get colder, will we see a white Christmas this year? In the last episode of the Big Questions podcast for 2023, Dr Neven Fučkar from the Environmental Change Institute tells us more about the science behind weather forecasts and how climate change is impacting Earth's weather patterns. Using advanced modelling, scientists can predict weather patt
How do you reintroduce lions?
Lions are iconic species, but they are threatened with extinction. In Zambia, researchers and conservationists are working together to find ways of conserving these majestic animals and preventing them from becoming by-catch of poaching. In this new episode of the Big Questions podcast, we speak to Dr Egil Dröge from the Department of Biology to share the steps involved in bringing lions back to a
Does banning smoking work?
As the UK government proposes new plans to reduce the number of people who smoke, we talk to behaviour change researcher Nicola Lindson from the Nuffield Department of Primary Care Health Sciences to find out how the plan would work. Could we see a generation that is smoke free? Would banning flavours in e-cigarettes stop children from taking up smoking? Tune in to the latest episode of the Big Qu
Why are deep fakes happening?
Welcome to the new series of the Big Questions podcast, where we ask Oxford scientists to shed light on everyday questions that you really want to know the answer to. Remember those photos or videos online that don't look quite right? Perhaps you've heard a celebrity's voice somewhere unexpected? In this episode, we chat to computational social scientist Dr Bernie Hogan from the Oxford Internet
What's the cool stuff that we've learnt from the James Webb Space Telescope?
About a year ago, we asked astrophysicist Dr Becky Smethurst why the James Webb Space Telescope is such a big deal. Her answers were pretty exciting, to say the least. So, in the months that have passed since then, what has it found out? What mysteries of the universe has it begun to unravel, and has it lived up to expectations? We got back in touch with Becky for an update. This is the last epis
Would you want to meet an alien?
What might an experimental petrologist (someone who makes rocks in the lab) and an immunologist (someone who studies the body's defence system) have in common? Well, it turns out, a shared interest in iron might be one thing. And what does all this have to do with aliens, and, specifically, whether you would want to meet one? Well, you'll have to listen to find out! With Prof Jon Wade from the Dep
Could 'Jurassic Park' actually happen?
"Life finds a way"...This year marks the thirtieth anniversary of the release of Stephen Spielberg and Universal Studio's dinosaur masterpiece 'Jurassic Park'. A rousing soundtrack, gutsy kids, and graphics which have stood the test of time remarkably well - the film has undeniably become a classic. But - here's the big question - could it actually happen? Using today's technologies, could we actu
How can we use sound waves to eliminate infections?
Many of us will have had to deal with a bacterial infection at some point or another. The solution? Often, antibiotics. But as the issue of antibiotic resistance becomes more and more of a concern, might there be an alternative to tackling bacterial infections with drugs? We chat to biomedical engineer Dr Sara Keller about how sound waves could potentially be used to break down bacterial cells.
How do you convert CO2 into jet fuel?
Increasing levels of CO2 in our atmosphere are a big cause for concern. So what if we could find a way to not only remove some CO2 from the air, but turn it into something useful too? That's exactly what Dr Tiancun Xiao and his team have been working on...and they've found a way to turn CO2 into jet fuel!
How do you use social media to deliver humanitarian aid?
Forced displacement of human populations owing to conflict or natural disasters is very difficult to measure. During these crises, the traditional methods of assessing changes in populations - which mostly rely on surveys - are simply not possible. We chat to Dr Douglas Leasure from Oxford's Leverhulme Centre for Demographic Science about how his team have been using social media data to assess th
How has life expectancy changed after the pandemic?
Demographers (researchers who study the statistics of human populations) look at factors such as birth rates, death rates, migration and life expectancy. But what exactly is meant by the term 'life expectancy'? How is it calculated, and how has it changed after the pandemic? We speak to Prof Jennifer Dowd from the Leverhulme Centre for Demographic Science to find out. You can find out more about P
Can you make a dengue fever forecast?
More than half the world's population is at risk from dengue fever, a viral infection that is spread via the bite of an infected mosquito. While some cases of the disease can be mild, others can be extremely dangerous and even fatal - particularly if someone has contracted the virus previously. When cases of dengue fever are high, those at risk can take some preventative measures, such as wearing
Can my gut health improve my mental health?
Our gut microbiome (that's all the microorganisms - such as bacteria, viruses and fungi - living in our gut) is really important for healthy digestion. But did you know that it's also linked to our mental health? In this episode of the Big Questions Podcast we chat to neuroscientist Prof Philip Burnet from Oxford's Department of Psychiatry about how our gut is connected to our brain, and how takin
Why do research on research?
We've talked about a lot of different types of research on this podcast...from investigations into drought, to space exploration, to the future of food. But what about researching 'research' itself? That's right, on this week's episode of the Big Questions Podcast, we're going meta! We chat to Dr Patricia Logullo, a meta-researcher from the Nuffield Department for Orthopaedics, Rheumatology and Mu
How could spider sex unlock secrets to engineering?
Not everyone is the biggest fan of spiders...we know that. They might not be the first thing that springs to mind when it comes to romance, either! But, you've got to admit, when it comes to engineering, they're pretty incredible. Capable of making up to seven types of silk, and able to sense vibrations through thousands of 'ears' on their legs, there's a lot we can learn from spiders when it come
Is the metaverse doomed?
Ask an internet aficionado what the 'next big thing' is, and they might respond with 'the metaverse'. This is the idea that we could soon be wandering in a virtual world - a kind of global, immersive video game. But are we really just one VR headset away from paradise? Or is the metaverse doomed before it's even really got off the ground? We chat to Dr Bernie Hogan from the Oxford Internet Institu
Can you cure jet lag?
If our internal body clock is telling us it's 3am, but the external environment is telling us it's 12 noon, that's called jet lag. It's a mis-match between what's going on inside our bodies and what's happening outside. Those who have travelled abroad - particularly to somewhere in a significantly different time zone - will be familiar with the feeling, but it's not just stepping off a plane that
Should I feel guilty eating turkey at my Christmas dinner?
While the tradition of eating turkey at Christmas can be traced back to Henry VIII, it's really only been a staple part of our Christmas dinner since the early 20th Century. However, in the UK, it's now hard to imagine a Christmas spread without a turkey at its centre! But - with meat consumption linked to negative impacts on both our health and the planet - should we feel guilty about enjoying th
How can a simulation help treat kidney stones?
Around 10% of us will experience kidney stones at some point in our life. They occur when waste products in the blood form small crystals, which gather together in the kidneys to form hard lumps. Small kidney stones (
How were new craters on Mars discovered?
When a space rock smashes into the surface of a planet, a hole - or crater - is formed. New craters might be relatively straightforward to identify on Earth, but what about on other planets, such as Mars? In this episode we hear from Dr Ben Fernando, a researcher from Oxford's Department of Physics and a scientist on NASA's InSight mission, about the techniques used to discover new craters on the
What makes the human brain so special?
We often hear that we're remarkably similar to our primate relatives, both in terms of our genetics and our behaviour. We're social beings. We use tools. But only humans have come to dominate the planet - why? Could the answer lie in the small differences between the human brain and that of other primates? In this episode of the Oxford Sparks Big Questions Podcast, we talk to neuroscientist Dr Rog
Why is the UK still in a drought?
Here in the UK, we have a reputation for grey, drizzly weather. But there's no denying that this summer was HOT and this summer was DRY. With soaring temperatures and little to no rain for weeks on end, it was no surprise that we found ourselves in a drought, with a ban on hosepipes declared and careful use of water encouraged. But, did you know that we're still in that drought? In this episode of
Why is the James Webb Space Telescope a big deal?
Are we alone in the Universe? What exactly lies at the centre of our galaxy? Just like our podcast, the James Webb Space Telescope aims to answer some *very big questions*. Launched on Christmas Day 2021 and hurtling towards an orbit 1.5 million miles from the Earth, the JWST (as it's known to those in the business!) is a follow-up to the Hubble Space Telescope - and it's three times bigger. Decad
What is green steel?
Steel has become an essential commodity in modern society - used in everything from our cars and our buildings to the cutlery we use to eat our dinner. Unfortunately, the process used to traditionally produce steel (mining iron ore and combining it with carbon in a blast oxygen furnace) releases a huge amount of CO2. So, is there a cleaner way of producing steel? In this episode, we chat to Prof B
How do you create autonomous robots that can investigate under the sea?
How do you retrieve data from sensors embedded in underwater settings - such as those monitoring ecosystem change, for example? Well, when human divers aren't an option (which is often the case) it's over to the autonomous robots! In this episode of the Big Questions Podcast we speak to Prof Nick Hawes from the Oxford Robotics Institute about the challenges - and possibilities - that such robots b
How do you grow the perfect tomato?
Is there anything nicer than a fresh, juicy, home-grown tomato on a summer's day? Whether you like them sliced up in a sandwich or blended into a delicious sauce, in this episode of the Big Questions podcast we reveal the secrets behind growing the perfect tomato. Let us transport you to Trap Grounds Allotments in Oxford, where Emily is joined by plant scientist Christian Norton, who is ready to r
How is misinformation about the war in Ukraine spreading?
Misinformation about the war in Ukraine - and countless other topics, such as the pandemic and climate change - spreads like wildfire online. It aims to confuse people, make them question their own knowledge, and ultimately raise suspicion and doubt. But how exactly does this misinformation spread, why is it so prevalent on social media, and what are the various platforms doing to help prevent it?
How does a pandemic end?
Masks, social distancing, lockdowns. We've become intimately familiar with numerous COVID-19 control measures over the past two years. Now, with most restrictions gone (at least here in England), does that mean that the pandemic is really over? In this episode, we chat to Erica Charters, Professor of the Global History of Medicine at the University of Oxford and Principal Investigator of the 'How
Why do we develop bad habits?
From biting our nails to idly scrolling on our phones, we all have those habits we wish we didn't. In this episode of the Big Questions Podcast, we chat to neuroscientist Charlotte Collingwood about what makes a habit, why we develop them, and how we might go about kicking a bad habit.
Is the energy crisis going to get worse?
Over the past year, we've seen our energy bills reach unimaginable heights. The war in Ukraine is having devastating effects for Ukrainians and creating ripples for international fuel costs. We're now in the midst of a 'perfect storm' when it comes to energy supply - but where are we in the story? Is the energy crisis going to get worse, and what are the potential solutions to bringing those price
