Firefighting is a career with an inherent cancer risk, but a full understanding of what those risks are has been elusive. An important registry designed to help understand the link between firefighters and cancer was taken offline on April 1 because of federal cuts, then restored six weeks later. Host Flora Lichtman discusses this with firefighter health researcher Sara Jahnke and reporter Murphy Woodhouse from Boise State Public Radio and the Mountain West News Bureau. Plus, pests and pathogens are ravaging keystone tree species in forests across the country. Flora discusses the innovative science behind breeding pest-resistant trees with Leigh Greenwood from The Nature Conservancy.Transcripts for each segment will be available after the show airs on sciencefriday.com.

What does it take to create and maintain one of the largest repositories of botanical information in the world? For starters, it can mean helicopter-ing into remote nooks of the Amazon, hiking through rough terrain, looking for strange fruits and flowers, and climbing trees to pluck specimens from the branches. Then there’s all the science required to identify, classify, and codify those species. Botanists Lúcia Lohmann and Charlotte Taylor join Host Flora Lichtman to discuss their work discovering new plant species and maintaining the storied Missouri Botanical Garden.And, what does it mean to be a superfood? What is the science of micronutrient-dense foods like millet, which get less hype than foods like açaí, goji berries, and quinoa? Flora talks with biological engineer Kiruba Krishnaswamy, who puts food under a microscope—literally—and studies the nutrients that help make our bodies function, in hopes of harnessing them to fight hunger worldwide.Guests: Dr. Lúcia Lohmann, professor at Washington University in St. Louis, and president and director of the Missouri Botanical GardenDr. Charlotte Taylor, botanist and senior curator at the Missouri Botanical Garden Dr. Kiruba Krishnaswamy, assistant professor in the Colleges of Engineering and Agriculture at the University of MissouriTranscript will be available after the show airs on sciencefriday.com.

Medical sculptor Damon Coyle walks around with a Mary Poppins bag of body parts. Fake ones, that is. At the University of Missouri, his lab creates hyperrealistic body parts designed to help medical providers practice for real-world surgeries and procedures. They make things like lifelike arms for practicing blood draws or a set of eyeballs for ocular trauma training. On stage in Columbia, Missouri, Damon talks with Host Flora Lichtman about how he creates these eerily realistic body parts and how they’re used.Guest: Damon Coyle, medical sculptor and innovation specialist at the University of Missouri in Columbia, Missouri. Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.
