For many travelers, Antarctica is a bucket-list destination, a once-in-a-lifetime opportunity to touch all seven continents. In 2023, a record-breaking 100,000 tourists made the trip. But the journey begs a fundamental question: What do we risk by traveling to a place that is supposed to be uninhabited by humans? And as the climate warms, should we really be going to Antarctica in the first place? SHOW NOTES: Kara Weller: The Impossible Dilemma of a Polar Guide Marilyn Raphael: A twenty-first century structural change in Antarctica’s sea ice system Karl Watson: First Time in Antarctica Jeb Brooks : 7 Days in Antarctica (Journey to the South Pole) Metallica - Freeze 'Em All: Live in Antarctica Learn about your ad choices: dovetail.prx.org/ad-choices…

What is it like to be on Countdown? 15:57

منذ 5 أيام15:57

15:57

"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 have 30 seconds to find a solution? Tom gives us a glimpse behind-the-scenes of this British institution.…

What happens after a dementia diagnosis? 14:35

منذ 19 يومًا14:35

14:35

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? 15:20

منذ 5 weeks15:20

15:20

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 created by those who experience stigma - can sometimes help challenge stereotypes and shift public perceptions. We chat with Dr Melina Malli from the Oxford Institute of Population Ageing to explore whether laughter can really be the best medicine.…

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.

How horny are hedgehogs? 15:20

منذ 9 weeks15:20

15:20

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's Day edition of the Big Questions Podcast, as we ask Dr Sophie Lund Rasmussen (aka Dr Hedgehog) "how horny are hedgehogs?"…

What can batteries of the future learn from eels? 12:00

منذ 11 weeks12:00

12:00

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? 11:17

منذ 13 weeks11:17

11:17

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 help to save the planet, or is it just there to annoy us? We chat to Dr Diogo Veríssimo about "nudge", "sludge", and changing human behaviour for a better world.…

Why are we seeing the Northern Lights more often? 13:19

منذ 15 weeks13:19

13:19

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 spectacle, and why now? Dr Carly Howett from the Department of Physics explains why we’re seeing the Northern Lights more often this year, and gives hope to those yet to catch a glimpse.…

Why track mistletoe? 13:40

منذ 19 weeks13:40

13:40

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 - importantly - how you can get involved with his research through MistleGO!…

Why are birth rates falling in the UK? 12:35

منذ 21 weeks12:35

12:35

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 anthropologist Dr Paula Sheppard about the drivers, and consequences, of this observed trend.…

What is a wind drought? 12:55

منذ 23 weeks12:55

12:55

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 to Matthew Wright from Oxford's Department of Physics to find out.…

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 sequence the genomes of over 70,000 species in Britain and Ireland. Discover the challenges and technological advances that make this monumental task possible, and explore the potential applications in fields like conservation genetics and evolutionary biology. Tune in to find out how this project could revolutionise our understanding of biodiversity and the future of life on Earth!…

What time is it on the moon? 14:45

منذ 42 weeks14:45

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 consequences of incorrect timekeeping be disastrous for space craft docking missions? If you want to get to grips with the weird and wonderful world of lunar time, then tune in to our latest podcast to find out more!…
