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 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?
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?
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?
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…
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…
