Explaining Science to my Dad L&L Shepherd

Lily has just about recovered from the excitement of the James Webb Space Telescope's first science images, and she's ready for Lloyd's next question: "How can we use a telescope to look for aliens?".

With support from Eva-Maria Ahrer (University of Warwick Centre for Exoplanets and Habitability), Lily helps Lloyd to understand how we use telescopes like JWST to figure out what's in the atmospheres of planets, and what this can tell us about life beyond our solar system.

Lloyd has been trying to eat more vegetables, but he can't stop thinking about cake. Which has got him wondering: why does cake taste so good if it's bad for us?

With help from the king of tasty tomatoes Professor Harry Klee (University of Florida) and author Mark Schatzker (The Dorito Effect, The End of Craving) Lily helps Lloyd to understand what flavour is, what makes food delicious, and why cake isn't actually all that bad for you.

Lloyd's spotted something interesting in the news recently: plastic-eating enzymes. This new method of recycling seems to be a perfect solution to plastic pollution, but could it really transform the way we use and re-use our plastic?

With help from Daniel Acosta (University of Texas Austin), who is a part of the team behind some ground-breaking new research into the enzyme FAST-PETase, Lily guides Lloyd through the fascinating world of enzyme engineering, and helps him to understand how enzymes could change the way we recycle forever.

With the reopening of the LHC and the launch of its newest experiment FASER, Lloyd's been reading about dark matter... and he's got questions. What is dark matter? And how on earth do you look for something you can't see?

With help from Dr Michaela Queitsch-Maitland (University of Manchester) and Savannah Shively (University of California Irvine), who both work on FASER, Lily helps Lloyd to understand what dark matter is, how we know it's there, and why we're closer than ever before to figuring out where it comes from.

Lloyd wants to know why Lily is a better than singing than him, so this episode's question is: "Why can we sing?"

With help from Nathan Welham from the University of Wisconsin Department of Surgery, Lily explains how human beings are able to use their bodies as instruments, and why some of us are just built better for singing than others.

In this episode, a question from listener Freddie - “What’s heavier, cold water or hot water?” - leads Lily and Lloyd into a discussion about why water is so important for life on Earth. 

With help from Elle Bethune from the UK Centre for Astrobiology, Lily explains how water’s weirdness helped life to form on our planet, and how it could help to create life on other planets in the universe.
