Science News Staff Writer Kelly Servick discusses how physicians have sifted through torrents of scientific results to arrive at treatments for SARS-CoV-2.

Sarah also talks with Wesley Reinhart of Pennsylvania State University’s Department of Materials Science and Engineering and Institute for Computational and Data Science, about why we should be building smart cities from smart materials, such as metamaterials that help solar panels chase the Sun, and living materials like self-healing concrete that keep buildings in good shape.

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