The cure for many conditions that inflict us may be found among the trillions of microbes that live inside our bodies. This hour, we’ll talk about the current state of microbial research with Rob DeSalle, curator of entomology in the Sackler Institute for Comparative Genomics at the American Museum of Natural History in New York City. He’s co-author of “Welcome to the Microbiome: Getting to Know the Trillions of Bacteria and Other Microbes In, On, and Around You” (Yale University Press).
