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.

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!

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! 

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.

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 household greenery is getting?

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 scientists know? Listen to our latest podcast to find out!
 
If you would like to learn even more about the volcanoes of Earth and beyond, why not give Tamsin’s new book, Adventures in Volcanoland, a read!
