This episode of Radiolab explores sulfur, an element typically associated with foul odors and decay, and reveals its surprising and vital roles in the human body and evolutionary history. Recorded in front of a live audience in Boston, the show investigates three interconnected stories: a mysterious 1994 hospital incident in California where a patient's body allegedly emitted toxic fumes, a catastrophic World War II munitions disaster in Bari, Italy, that inadvertently led to the creation of chemotherapy, and scientific discoveries showing how brain cells use hydrogen sulfide to build and strengthen memories. Together, the hosts and guests argue that despite our evolutionary aversion to its stench, sulfur is fundamentally tied to life itself.
The episode opens with the hosts greeting listeners and introducing themselves before segueing into the first story.
A detailed recounting of the 1994 Riverside, California ER event where staff fell ill after a patient’s arrival.
Scientists uncover sulfur compounds in the patient’s blood, leading to speculation about toxic exposure and mass hysteria.
The hosts recount the 1943 Bari bombing, the accidental release of mustard gas, and its hidden role in advancing chemotherapy.
The Mysterious Hospital Incidentstory
In 1994, a dying cancer patient named Gloria Ramirez arrived at an ER in California, and medical staff began passing out one by one after drawing her blood, prompting a bizarre toxic-fume theory.
Mass Hysteria Versus Toxinsdebate
State investigators concluded the hospital collapse was an episode of mass hysteria among stressed female workers, while independent lab analysis suggested chemical transformations produced an airborne toxin.
Extreme Olfactory Sensitivitydata
Humans can detect sulfur at concentrations as low as 0.5 parts per billion, an acute sensitivity shaped by evolution to warn us against rotting flesh and toxic decay.
A Nazi air raid on Bari, Italy, in 1943 hit an undisclosed American ship carrying secret mustard gas bombs, exposing hundreds of allied sailors to the burning agent.
From Poison to Medicineinsight
An American doctor investigating the Bari disaster noticed that mustard gas decimated white blood cells, inspiring the revolutionary idea to use toxic chemicals to fight leukemia and tumors.
Brain Farts or Memory Gasinsight
A scientist studying rat brains discovered that hydrogen sulfide gas was naturally present in the brain, initially dismissing it as metabolic exhaust before realizing it plays a crucial functional role.
Reversing Alzheimer's in Micedata
Researchers found that mice depleted of hydrogen sulfide showed memory deficits similar to Alzheimer's, and pumping them with the gas prevented or reversed those learning deficits.
Ancient Origins of Lifeinsight
Before oxygen filled Earth's atmosphere, early microbes near deep-sea hydrothermal vents used sulfur as their primary source of energy and life.
What if the smell of death is actually the smell of life?
