First up this week, we hear about caves on the Moon, a shake-up at Pompeii, and the iron-lined teeth of the Komodo dragon. Reporter Phie Jacobs joins host Sarah Crespi to discuss these news stories and more from our daily newsletter, ScienceAdviser.

Next on the show, electron microscopes allow us to view a world inaccessible to light—at incredible resolution and tiny scales. But bombarding samples with a beam of electrons has downsides. The high-energy electrons used for visualizing minute structures can cause damage to certain materials. Jonathan Peters, a research fellow in the School of Physics at Trinity College Dublin, joins the podcast to talk about a new approach that protects samples while keeping resolution sharp.

This week’s episode was produced with help from Podigy.
