Radiolab

→ WHAT IT COVERS Radiolab's "Atomic Artifacts" traces the U.S. government's secret Cold War doomsday planning, revealing a classified list of seven artifacts chosen to preserve American national identity after a nuclear attack, then asks contemporary Americans which objects should represent the nation today. → KEY INSIGHTS - **Cold War nuclear survivability calculus:** 1950s government planners operated under the assumption that a Soviet first strike would deliver roughly 50–60 Hiroshima-scale...

→ WHAT IT COVERS Radiolab's "The Gondolier" follows Alex Hay, a transgender man who spent nearly 20 years publicly misidentified as the first female gondolier in Venice's 900-year, all-male tradition. The episode traces his fight against the gondoliers' association, his physical transition at 50, the confiscation of his gondola Pegasus in 2019, and his eventual resettlement in Berlin.

→ WHAT IT COVERS Neuroendocrinologist Emily Jacobs and grad student Laura Pritchett conducted the "28" experiment at UC Santa Barbara, scanning Laura's brain daily across a full menstrual cycle to document how estrogen and progesterone physically alter brain structure, connectivity, and neuroplasticity — findings later replicated in a male subject tracking testosterone's 24-hour rhythm.

→ WHAT IT COVERS Radiolab's Terrestrials explores wild animal fatherhood across six species — owl monkeys, seahorses, poison dart frogs, Darwin frogs, burying beetles, and stickleback fish — revealing that intensive paternal caregiving, including pregnancy, piggyback transport, and nest-building, is widespread in nature and challenges human assumptions about "natural" dad behavior.

→ WHAT IT COVERS Radiolab presents excerpts from On the Media's four-part series on FEMA, tracing the agency's origins from Cold War nuclear bunkers through conspiracy theories, Hurricane Katrina failures, Hurricane Helene misinformation, and the Trump administration's 2025 push to abolish or rebrand the 20,000-person federal disaster relief agency. → KEY INSIGHTS - **FEMA's dual-mission problem:** When Jimmy Carter created FEMA in 1979 by merging five agencies, it inherited two conflicting...

→ WHAT IT COVERS On September 22, 1975, Oliver Sipple grabbed Sarah Jane Moore's arm as she fired at President Gerald Ford outside San Francisco's St. Francis Hotel. His act of heroism triggered a chain of events involving Harvey Milk, the press, and a landmark privacy lawsuit that destroyed Sipple's family relationships and contributed to his death at 47 in 1989.

→ WHAT IT COVERS RadioLab reporter Alex Neeson documents her multi-month attempt to overcome a severe cockroach phobia through three escalating strategies: shadowing New York City exterminators, attempting to eat American cockroaches prepared by edible insect chef Joseph Yoon, and researching the species' history with entomologist Sammy Ramsey and science writer Bethany Brookshire.

→ WHAT IT COVERS Three stories examine how societies assign dollar values to human life and nature. Memorial Sloan Kettering oncologists challenge a $30,000 cancer drug yielding 42 extra days; a Yemen drone strike raises questions about condolence payments; Chinese apple farmers replacing extinct bees reveal the limits of economic valuation of ecosystems.

→ WHAT IT COVERS Radiolab revisits its 2009 hookworm episode with a 2024 update from Dr. Paul Jackaman at the Australian Institute of Tropical Health and Medicine, examining clinical trial evidence that hookworm infections may reduce insulin resistance, improve metabolic health, and potentially treat autoimmune conditions including Crohn's disease and celiac disease.

→ WHAT IT COVERS Radiolab's "The Bad Show" examines human capacity for harm through three lenses: Stanley Milgram's obedience experiments revealing 65% of ordinary Americans administered what they believed were lethal shocks, Fritz Haber's dual legacy feeding billions while pioneering chemical warfare, and Green River Killer Gary Ridgway's 49 murders and his detectives' fruitless search for a coherent "why.

→ WHAT IT COVERS Animal rights activist Wayne Chung, co-founder of Direct Action Everywhere, breaks into a Smithfield Foods pig farm in Utah in 2017, removes two sick piglets named Lily and Lizzie, and represents himself at trial — forcing a jury of locals in a pro-Smithfield county to confront the unanswerable legal question of what an animal's life is worth.

→ WHAT IT COVERS Radiolab revisits forest science by exploring tree canopies in old-growth forests, where ecologists Nalini Nadkarni and Karina Mifune discovered soil ecosystems, aerial root systems, and nutrient reserves hidden up to 100 feet above ground. → KEY INSIGHTS - **Canopy soil depth:** Old-growth redwood and maple trees accumulate up to three feet of soil on their branches, formed from decades of decomposing moss and leaves.

→ WHAT IT COVERS Danish journalist Clara Groenel investigates why cows on farms near power infrastructure refuse water and drink each other's urine. The trail leads through Wisconsin stray voltage lawsuits, a decades-long scientific debate over cow electrical resistance, and a disputed 2016 Idaho study challenging the foundational 500-ohm standard used in farm safety regulations.

→ WHAT IT COVERS Radiolab's Terrestrials episode traces how beavers — nearly hunted to extinction for the 17th-century fur trade — returned to New York City's Bronx River after a 200-year absence, and how a single beaver family in Northern California protected roughly 7.5 acres from wildfire during the devastating 2021 fire season. → KEY INSIGHTS - **Beaver dam water filtration:** Beaver dams function as natural water purification systems, trapping agricultural chemicals, pollutants, and...

→ WHAT IT COVERS Three Radiolab reporters examine whether life operates through order or chaos, drawing on a decades-long barrel ecosystem experiment in Germany, a 1972 computer simulation of extinction at Woods Hole, and competing theories about life's origin — from primordial soup to deep-sea hydrothermal vents. → KEY INSIGHTS - **Ecosystem Stability Myth:** Ecologist Reinhardt Hercloss monitored a sealed 100-liter Baltic seawater barrel for over six years expecting equilibrium — either a...

→ WHAT IT COVERS ER doctor Avir Mitra traces antibiotic resistance from a 2006 MRSA study co-authored with his physician father through his decade of frontline clinical experience, revealing how bacterial evolution, agricultural antibiotic overuse, and a stalled drug pipeline converge into a global health crisis — then examines phage therapy as a viable emerging countermeasure.

→ WHAT IT COVERS Radiolab traces the antibiotic resistance crisis from Alexander Fleming's 1928 penicillin discovery through today's MRSA superbugs, then follows microbiologist Freya Harrison and historian Christina Lee as they test a 1,100-year-old Anglo-Saxon eye remedy from Bald's Leechbook against drug-resistant staph bacteria. → KEY INSIGHTS - **Antibiotic Resistance Timeline:** Every major antibiotic has faced resistance within months to years of release — methicillin lasted just eleven...

→ WHAT IT COVERS Radiolab traces the New World screwworm — a flesh-eating fly parasite eradicated from North America using USDA entomologist Edward Nippling's sterile insect technique starting in 1957 — and examines its current northward resurgence from Panama toward the U.S. border, alongside the ethical debate over using gene drives to permanently extinct the species.

→ WHAT IT COVERS Radiolab host Molly Webster and executive editor Soren Wheeler explore the surprisingly complex reproductive biology of snails with evolutionary biologist Menno Schilthuizen from Leiden University, covering hermaphroditic anatomy, multi-hour mating sessions, three-foot slug penises, and calcium-tipped "love darts" that chemically manipulate partners to increase fertilization success.

→ WHAT IT COVERS Three unsolved "black boxes" examined across science and mystery: how anesthesia erases consciousness at the neural level, how 1950s BBC radio mind-readers the Piddingtons fooled 20 million Australian listeners without anyone decoding their method, and how caterpillars dissolve into cellular soup inside a chrysalis yet emerge as butterflies carrying memories from their prior form.
