Summary
This Radiolab episode explores the overlooked element sulfur through three distinct stories. ER doctor Averi Mitra recounts the 1994 Riverside ER incident where a patient’s death caused mass fainting, potentially linked to sulfur compounds. Historian Jeanette Conant details the 1943 Bari disaster, where a secret mustard gas shipment poisoned Allied troops and inadvertently launched modern chemotherapy research. Finally, the show examines hydrogen sulfide’s vital role in brain function and memory, revealing how this toxic gas is essential for learning and may help combat Alzheimer’s.
