| 9/2/26 | Ep. 50: I See a Bad Moon Rising | A blue diamond mailed through the regular postal service. A pharaoh's tomb blamed for deaths that had nothing to do with him. A Porsche that vanished from a locked trailer. A Raggedy Ann doll two student nurses swore was moving on its own. This week Crystal and Andrea go owner by owner, deathbed by deathbed, through history's most famous "cursed" objects, and dig into what's actually killing people versus what's just an excellent sales pitch. Spoiler: one jeweler wrote a curse clause into an actual legal contract to close a deal. | — | ||||||
| 8/26/26 | Ep. 49: Then I Saw Her Face | Most people can barely recall a stranger's face after a few minutes. Then there are the outliers, the small slice of the population who can pick a face out of a crowd years later, from a single glimpse, even through disguises. We dig into the research on super recognizers: how scientists identify them, what's happening differently in their brains, and how police departments and border agencies have started recruiting them as real investigative tools. It's a rare case where a "superpower" isn't science fiction, it's just measurable human variation. In this episode, Andrea and Crystal break down what the studies actually show, and what it means for the rest of us who can barely remember a name at a party. | — | ||||||
| 8/19/26 | Ep. 48: Breathe In, Breathe Out | Ever wondered how we went from "just sleep on your side" to strapping a machine to your face every night? In this episode, Crystal and Andrea dig into the surprisingly wild history of the CPAP machine — from a wine bottle and a vacuum cleaner motor in an Australian lab to the sleek, quiet devices millions of people rely on today. We trace the invention back to Dr. Colin Sullivan's 1981 breakthrough, the decades of trial, error, and skepticism that followed, and how CPAP went from a clunky lab experiment to the gold-standard treatment for sleep apnea. Whether you're a longtime CPAP user, a curious insomniac, or just love a good "who knew?" origin story, this one's for you. | — | ||||||
| 8/12/26 | Ep. 47: I'm Half the Man I Used to Be | At 19 years old, Loren Schauers made a choice most of us will never have to face.This week, Andrea and Crystal cover the story of a young man whose ordinary workday on a bridge construction site turned into a fight to survive an accident that should have killed him instantly. We break down the injuries, the split-second decisions that saved his life, and the radical surgery that let him keep living, even after losing half his body. It's a story about the limits of the human body, and what it takes to keep going when everything changes in an instant. | — | ||||||
| 8/5/26 | Ep. 46: Tell Me Lies | Medicine promises the same standard of care to everyone. History tells a different story. In this episode, Andrea and Crystal dig into the disparities baked into modern medicine, who gets diagnosed, who gets believed, and who gets left behind. Two RNs unpack the data, the cases, and the consequences. | — | ||||||
| 7/29/26 | Ep. 45: War Pigs | He was a physician. He held the rank of general. And for over a decade, he ran one of the most horrifying human experimentation programs in modern history — and walked away from it a free man.This week, we head to Manchuria to unpack the story of Unit 731, the covert biological and chemical warfare research unit of the Imperial Japanese Army, and the doctor who built it. We're talking vivisection without anesthesia, deliberate frostbite experiments, and weaponized plague fleas — all conducted under the banner of "scientific research." We'll walk through how a licensed physician convinced his government to fund it, why the victims were stripped of even the dignity of a name, and how a deal with American occupation forces after the war meant almost no one was ever held accountable.As two nurses, this one hit different. We talk about what it means when the Hippocratic Oath gets weaponized, and how the West's Cold War priorities let a war crime of staggering scale disappear from most history books entirely.** Content note: this episode discusses graphic human experimentation and wartime atrocities. | — | ||||||
| 7/22/26 | Ep. 44: I Fell In to a Burning Ring of Fire | A machine that was supposed to heal became one of the deadliest medical devices of the twentieth century, and nobody could figure out why. This week, we dig into the Therac-25, a radiation therapy machine whose software errors delivered massive, lethal overdoses to patients across the US and Canada in the mid-1980s. We walk through the race condition bugs that let operators override safety checks in a matter of keystrokes, the manufacturer that dismissed early reports as impossible, and the investigation that turned this into one of the founding case studies in software safety engineering. It's a story about how a few lines of bad code became a body count. | — | ||||||
