How are seals affecting fishing catches?
Oxford Sparks Big Questions
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 fisheries. Tune in to find out how understanding more about the behaviour of the UK’s seal populations can shape marine management policies.

Why am I killing my house plants?
Oxford Sparks Big Questions
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 much water to your house plants, it starves their roots of oxygen, damaging the root system and actually creating a drought? And have you considered how much light and ventilation your...

How are volcanoes formed on other planets?
Oxford Sparks Big Questions
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, providing evidence of a long lost hot spot beneath the surface. What about the rest of the solar system? There are glimpses of volcanism on Venus and Jupiter’s moon, Io, too. But how do...

Can we talk to bees?
Oxford Sparks Big Questions
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. To understand more about bee behaviour, Rachel has created a series of small arenas with cameras and microphones. Using AI, visual and audio recordings can be matched up to create...

Why are people obsessed with how cute cats are?
Oxford Sparks Big Questions
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 decides that something is cute. This almost instantaneous cuteness reaction is thought to be a deep-rooted evolutionary feature of humans, encouraging us to look after young babies and animals to help...

How freaked out should I be about bed bugs?
Oxford Sparks Big Questions
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 pesticides, bed bug populations declined significantly after the Second World War. However, as pesticide resistance grows and the world becomes increasingly connected, bed bugs are making a resurgence....

When did we start kissing?
Oxford Sparks Big Questions
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 back to 2500 BCE. But animals can also help us to answer this question. Bonobos have been shown to kiss romantically to strengthen pair bonds and assess a mate’s suitability. Perhaps...

How do you stay warm in your house without central heating?
Oxford Sparks Big Questions
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 inexpensive methods you can try to stay toasty, starting with the idea of heating the human rather than the home. Tune in to learn more!

How will climate change affect wine?
Oxford Sparks Big Questions
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 growing conditions were like for the grapes in a given year – was it hot or cold? Was there flooding or drought? Was light more intense? As the UK experiences more ‘BBQ summers’, we may...

What are the odds of a white Christmas?
Oxford Sparks Big Questions
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 patterns to different degrees of certainty. So in a few days’ time, we should know whether we will see snow on the big day. But what do the predictions look like for the next five or ten years? Find...
info_outlineIf 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 can cause it. 'Social jet lag' is a particular problem for shift workers, for example. An out-of-sync body clock can make us feel terrible, so, is there a cure for the condition on the horizon? We speak to neuroscientist Prof Aarti Jagannath from the Nuffield Department of Clinical Neurosciences about her work investigating potential drug treatments for jet lag.
