Readers interested in getting an inside peek into the research behind some of National Geographic's explorations may enjoy their podcast Overheard. Launched in June 2019 and currently in its second season, this podcast features engaging stories from "the explorers, photographers and scientists at the edges of our big, bizarre, and beautiful world." For example, in "Cave of the Jaguar God," Guillermo de Anda, an archaeologist and researcher with Mexico's National Institute of Anthropology and History, shares what it was like to enter an extraordinary cave used by the Maya that had been untouched for centuries. Another episode, "March of the Beaver," takes listeners to the Alaskan tundra, where beavers are playing a surprising role in the northward shift of larger species as climate change warms the Arctic, while "The Aquarius Project," in which an actor leads group of high school students in searching for a meteorite at the bottom of Lake Michigan, demonstrates that sometimes all science needs is determination and tenacity. Episodes are generally 15-25 minutes long and each episode's page includes transcripts, as well as beautiful photographs. In addition to streaming Overheard online at the link above, interested readers can find it on their favorite podcast app.
