Ep. 7 - dysprosium
This week on Them Their Hills, we get cozy with an actual rock doctor, Emilia, and our mineral of the day dysprosium, our “hard-to-get,” never-found-alone rare earth that quietly powers wind turbines, nukes, lasers, and probably the radio you’re listening on. Emelia and I wander such topics as the magnets in our brains, geology, governors, and why critical minerals aren’t as easy to rally around as fish or cheap energy. Plus: the definitive PSA: don’t lick mystery rocks, especially the volcanic, sulfide-smelling ones.
