Imagine stepping into a white suit, pulling on thick rubber gloves and a helmet with a clear face plate. You can only talk to your colleagues through an earpiece, and a rubber hose supplies you with breathable air. Sounds like something you wear in space, right? In this case, you’re not an astronaut. You’re at the Texas Biomedical Institute in San Antonio, one of the only places where the most dangerous pathogens—the ones with no known cures—can be studied in a lab setting. Dr. Jean Patterson, a professor there, and Dr. Ricardo Carrion, professor and director of maximum containment contract research, join Ira live on stage for a safe peek inside the place where the world’s deadliest diseases are studied. Bracken Cave, 20 miles outside of San Antonio, is the summer home to 15 million Mexican free-tailed bats. Each night, the bats swarm out of the cave in a “batnado“ in search of food. Fran Hutchins, director of Bat Conservation International’s Bracken Cave Preserve, talks about how the millions of individuals form a colony and the conservation efforts to preserve this colony in the face of housing developments and the encroaching city. San Antonio is a great place for birding. Along with Texas Hill country, the Edwards Plateau, and the gulf coast, the region’s intersecting ecosystems make it a good home—and a welcome pitstop—for birds. Iliana Peña, the Director of Conservation Programs at the Texas Wildlife Association, talks about sustainable grazing and other changes to ranching procedures that would make the tracts of land held by large Texas landowners more welcoming to grassland birds. Plus, Jennifer Smith, an assistant professor in the Department of Environmental Science and Ecology at the University of Texas at San Antonio, describes her research on the effects of wind farms on prairie chickens in Nebraska.
