Metals are everywhere. From iron to sodium, magnesium to calcium, metals are in our bodies and in the technology we use every day. In this week's Lab, we're doing a deep dive straight into the earth's crust to talk all about what metals are used for, why they're so important, and what plans are in place to preserve (or imitate) these limited natural resources. Guest: Dr. Kate Buettner. You can find more Dope Labs, show notes, and cheat sheets at dopelabspodcast.com.
