One way to delve deep into the ancient history of the Earth - or other planetary bodies for that matter - is to examine the magnetism recorded by rocks. Kind of like a fossilised magnetic fingerprint. But trying to do this in an environment where another magnetic field exists (i.e. everywhere on Earth!) is pretty challenging. Enter the 'magneticall…
 
"Rudolph the red-nosed reindeer, had a very shiny nose..." Many of us will be very familiar with Santa's famous antlered friend. But did you know that many reindeer actually do have red noses? But why? In this festive episode of the Big Questions Podcast, we ask Oxford polar biologist Ignacio (Nacho) Juarez Martinez to share some of the reasons we …
 
Online communication channels are popular, to say the least. For instance, there are 187 million active Twitter users per day alone. Sadly, these open channels of communication also open up the potential for harm, through online hate speech. The problem is so large that we require AI to help detect it. But what about when it comes to emoji? Accordi…
 
In the early days of the COVID-19 pandemic there was a lot of confusion, as we all tried to figure out what we should and shouldn't do to best protect ourselves and others. Fortunately, we now have more definitive answers to some of our most pressing questions - which are backed-up by data - including "umm...should I be wearing a mask?". As COVID c…
 
Satellites have been orbiting our planet for the past few decades. We might be familiar with how they can be used to track weather, or beam television and phone signals around the world. But did you know, that by capturing images of the Earth outside the visible spectrum, they're able to offer a unique perspective of the ground beneath our feet? Th…
 
From California to Greece to Australia, it seems like every time we switch on the news there's another wildfire report. Some fires are natural - in fact, they're a fundamental part of many ecosystems - but the severity and frequency of the wildfires we are now witnessing is beyond natural levels. Human-ignited "megafires" are causing devastation ac…
 
Chocolate. It’s rare to find anyone who isn’t partial to a square or two of this delicious treat. But is its very existence in danger? (*Cue worried faces.*) In this episode of the Big Questions Podcast we chat to chocoholic and researcher Acheampong Atta-Boateng, who studies the relationship between cocoa trees and their micro-pollinators. We hear…
 
Nowadays, the idea of encountering robots in our daily lives isn't pure science fiction. Many of us interact with AI every day, and the use of robots in, for example, healthcare settings, is already on the horizon. But what if something goes wrong? The RoboTIPS team at the University of Oxford is developing an innovative feature - an 'ethical black…
 
Do you remember when the price of fizzy drinks in the UK went up slightly a few years ago? Soda fans, perhaps you remember all too clearly...! Well, this was because the UK government introduced a sugar tax (or the Soft Drinks Industrial Levy, to be precise), requiring manufacturers to pay a tax on sugary drinks - a cost which was then passed on to…
 
An arboretum could be described as a "living library". A beautifully curated collection of woody plants from across the globe, each one carefully labelled and managed. In this episode of the Big Questions Podcast we chat to Ben Jones, Arboretum Curator at the University of Oxford Botanic Garden and Harcourt Arboretum, about what makes an arboretum …
 
Lockdowns, social distancing, restrictions on 'normal' activities - we've all been affected by the COVID-19 pandemic. But how has it impacted on our mood and mental wellbeing? We chat to Dr Maxime Taquet from the Department of Psychiatry about 'mood homeostasis' (the interplay between people's activities and the way they feel), and how this has bee…
 
Their distinctive 'teacher teacher' call is synonymous with British gardens, but great tits are facing a big problem - climate change. As our springtime becomes warmer and begins earlier, peak caterpillar abundance is also shifting earlier. As a crucial food source for great tit chicks, this is cause for concern. In this episode of the Big Question…
 
Remember those days when it was possible to climb aboard a plane and jet off around the world? Well, while we might be yearning for foreign shores, there's no denying that air travel comes with a big ol' carbon footprint. But is it possible to make aeroplanes 'greener'? We chat to Dr Chiara Falsetti, a researcher at the Oxford Thermofluids Institut…
 
The moon may be the closest planetary body to us, but we still have a lot to learn about it. For example, what is the water-cycle like on an airless body such as the moon? How much water can be found there, and could we one day utilise this water for space exploration? In this episode of the Big Questions Podcast, we chat to Dr Katherine Shirley, a…
 
We're over a year into the coronavirus pandemic, and it's affected our lives in many ways - including, for many of us, how we sleep. You may have experienced changes to your sleep pattern (particularly if you waved goodbye to your commute last March), your quality of sleep, or even had some very weird or vivid dreams! If so, you're not alone. Join …
 
If you've ever been lucky enough to hear a lion roar (whether that's at the zoo or in the wild - hopefully at a safe distance!), you'll know that it's a truly bone-shaking experience. But do lions have a unique roar, or do they all sound the same? How could knowing this help with conservation efforts? Join us for this episode of the Big Questions p…
 
In this year's Valentine's episode, we're exploring one of the most special relationships around. That's right - the one between us and our dogs! We often hear pooches described as "(wo)man's best friend", but for how long has this been the case? Join Prof Greger Larson, an expert in palaeogenomics and bio-archaeology, as we journey back thousands …
