'Will my bacon sandwich kill me?', 'Is vaping better than smoking?', 'How do you become an astronaut?' - just some of the Big Questions we ask some of the brightest minds behind Oxford science. Join us in each podcast as we explore a different area of science.

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 impa...
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...
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.

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.
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 Department of Earth Sciences.
"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 actually extract ancient dinosaur DNA f...
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.
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!
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 the internal displacement of populati...
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 Prof Dowd's work in our micro-docume...
