The Western Black Widow (Latrodectus hesperus) is a master of invisible chemistry. 2026 Science Podcast of the Year winner Dr. Jeffrey Zurek joins Dr. Andy Fisher (Greifswald University) to untangle the chemical love letters hidden in spider silk. We explore how "virtually blind" predators use smell & electrostatic charges to communicate. Discover the "stinky cheese" pheromone, why males destroy female webs during courtship, and the scandalous truth about "cheating" widows who lie about their age and fitness to attract a mate. Topics Covered • Podcast of the Year: Celebrating 2026 American Writing Awards win. • Chemical Languages: How smell and taste dominate the "dark taxa." • Explore the sausage-making of science, & how chemical ecology replaces toxic pesticides • The "Gym Sock" Signal: Identifying butyric acid in widow webs • Honest vs. Deceptive Signals: How starved spiders "cheat" the system • New Anatomy: Hot-off-the-press research on how spiders smell with their legs.
