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

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 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!

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 encouraged! This is the final episode of this season. We hope that you have enjoyed learning the science behind the many weird and wonderful aspects of our world. If you have a big question, get in touch and we will try to find you an answer in the next season.

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 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!

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 produced by the waves hitting the UK’s coastline. Find out more about this imaginative approach to scientific discovery in this podcast!

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. With only a brain nested in the skull, we are asking … how can this happen? Listen now to find out and discover how this research is unravelling ancient human history!

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 note has played. But what you really want to know is how to get rid of an earworm, right? Tune in to find out!

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 fisheries. Tune in to find out how understanding more about the behaviour of the UK’s seal populations can shape marine management policies.
