Jersey City's Secret Water Experiment
How did a covert chemical treatment permanently change our drinking water? In 1908, two men, John L. Leal and George Warren Fuller, spent 99 days secretly constructing something that would fundamentally alter the Jersey City water supply. Their decision to add chlorine is one that continues to impact our lives for the better, but there was no large-scale testing or approval process. This episode,
Cigarettes in America, Part 2: The Reckoning
Cigarettes: they provide no nutrition and quench no thirst. They serve no purpose other than being an excuse to take a break from the grind before getting right back to it. And on top of that, they're deadly. As far as American vices go, they might be at the top of the list. So how did they get and stay popular for so long? And why are they making a comeback?

The CRISPR Babies
In 2018 news broke that a Chinese scientist, He Jiankui, had used CRISPR to edit human embryos, and twin girls had been born as a result. The story set off an explosive bioethical controversy. As gene editing expert Kiran Musunuru put it, "He Jiankui's genetic misadventures were the biggest medical story of the century so far." Both scientists and the public had a lot of questions. What was the u
Humans and Monsters: An Interview with Surekha Davies
The fears about genetic engineering were stoked when experiments took off in the 1970s. From lab leaks to disease epidemics to the ability to make "Frankenstein creations," many of those fears are still with us today. We talk to author Surekha Davies about her latest book, why she thinks of monsters as category breakers and why blurring boundaries can be so terrifying for us, but maybe doesn't hav
IVF: An Interview with Robin Marantz
Our producer Rigoberto Hernandez spoke with Robin Marantz, the author of Pandora's Baby: How the First Test Tube Babies Sparked the Reproductive Revolution. She tells us about the history of IVF, from the first known artificial insemination by donor produced in Philadelphia in the 19th century to the scientific race in the 1960s and 1970s that resulted in the first so-called "test-tube baby."

When Rebekah and Evan Lockard's daughter, Naomi, was diagnosed with a devastating ultra-rare genetic disease, they didn't know where to turn. Then they found Terry Pirovolakis, an IT professional who had made a gene therapy for his son with the same disease. But the process of getting Naomi treated has been an uphill battle, full of financial and logistical obstacles. The Lockard's story flips the
Gene Therapy's Dark Ages
Gene therapy is based on a simple-sounding, yet deceptively complicated premise: adding or replacing faulty genes to fix medical problems. A compelling idea that came out of breakthroughs in DNA research, the field grew lightning fast. But the death of teenager Jesse Gelsinger after a gene therapy clinical trial left the public and scientists questioning the field's promise. Why did researchers p

The History of the School Lunch
Feeding kids a healthy lunch every school day is a feat of science and logistics. Molded into shape by nutrition scientists who wanted to optimize children's health, the school lunch has endured war, economic depression, and even a global pandemic. Some might say it's all the stronger for it. So how did all these crises shape school lunch? And is there any room to give our rectangle pizzas and fro
ALS Patients Take on the FDA
ALS is a fatal neurological disease that kills motor neurons. Even though it was first described more than 150 years ago, there is no cure, and the few drugs available only dampen the symptoms or slow the progression by a few months. In recent years new drugs have emerged. However, there is one problem: the life expectancy is just two to five years after diagnosis. This timeline is incompatible wi
The Fraud that Transformed Psychiatry
In 1973 a bombshell study appeared in the premier scientific journal Science. It was called "On Being Sane in Insane Places." Its author, a Stanford psychology professor named David Rosenhan, claimed that by faking their way into psychiatric hospitals, he and eight other pseudo-patients had proven that psychiatrists were unable to diagnose mental illness accurately. Psychiatrists panicked, and,
Cancer Virus Hunters: An Interview with Gregory J. Morgan
For more than 100 years, biologists who suggested that some cancers may be caused by viruses were the pariahs of genetics. However, they persevered and incrementally built their knowledge, leading to the discovery of retroviruses, the development of a test to diagnose HIV, and the creation of the HPV vaccine. Join us as we interview Gregory J. Morgan about his book Cancer Virus Hunters: A History
The Ames Test
In 1973 biochemist Bruce Ames created a simple test that showed if chemicals had the potential to cause cancer. The Ames test made him a hero of the emerging environmental movement. But then he completely changed course and said concerns about chemicals were overblown. So what happened? Did Ames change? Or did our understanding of what causes cancer change?

Is Ozempic Different?
Ozempic and others in this family of drugs are nothing short of miraculous. Meant to treat Type 2 Diabetes, the drug exploded in popularity after researchers found that patients were reporting losing 15-21% of their body weight in clinical trials. There were some side effects, but none so severe that it raised concerns. Doctors began prescribing it to people who weren't diabetic but could benefit
Traffication: An Interview with Paul Donald
The impact of cars on wildlife extends beyond roadkill, affecting species that never venture near roads. Car noise disrupts bird communication and behavior, and tire and brake dust from pollutes waterways with microplastics. In this wide-ranging interview, we talk to the author of Traffication: How Cars Destroy Nature and What We Can Do About It, Paul Donald about how he coined the term "trafficat
Dyes, Drugs, and Psychosis
In 1856, Henry Perkin's attempt to synthesize quinine led to something very different: a vibrant purple dye. Perkin's mauve revolutionized the fashion industry when Queen Victoria wore a dress of the color to her daughter's wedding. And in an ironic twist, synthetic fabric dyes ultimately led to synthetic drugs, including the first antipsychotic. This drug, known by its trade name Thorazine, was a
Pink: An Interview with Dominique Grisard
The color pink has long been in vogue, and when Barbie hit theaters in 2023, its appeal only increased. But its popularity dates back much further than the Mattel doll. In this bonus episode, Dr. Dominique Grisard, a gender studies professor at the University of Basel, discusses the hue and its ties to femininity, class, and Whiteness, as well as how pink has been used to subdue men in detention c
Can Color Heal Us?
For centuries people have been drawn to the potential healing powers of colored light. From a civil war general to a Thomas Edison wannabe, people have touted it as a medical miracle. Despite claims to the contrary, though, colored light won't regrow limbs or heal burns. And yet, we are still drawn to the idea that somehow it can fix us. Today there are actual medical studies investigating the hea
The Word for Blue
In his epic poem, The Odyssey, Homer mentions the colors black, white, red, and yellow. But despite numerous mentions of the brilliant Greek sea and sky, the word blue never makes an appearance. This omission set off a debate between perception and language that would repeat itself over and over again throughout history: was there something wrong with the ancient Greek's eyes? If they didn't name

Exploring 'Health Equity Tourism'
In the wake of the murder of George Floyd and the COVID-19 pandemic, there has been a new public interest in health inequities research. With this new focus, there also has come new funding with many researchers and institutions clamoring to receive lucrative funding and recognition in the field, but there are no official guidelines to distinguish a health equity expert. In this episode we sit dow
The Mothers of Gynecology
Of all wealthy countries, the United States is the most dangerous place to have a baby. Our maternal mortality rate is abysmal, and over the past five years it's only gotten worse. And there are huge racial disparities: Black women are three times more likely to die than white women. Despite some claims to the contrary, the problem isn't race, it's racism. In this episode we trace the origins of t
Correcting Race
Certain medical instruments have built-in methods of correcting for race. They're based on the premise that Black bodies are inherently different from White bodies. The tool that measures kidney function, for example, underestimates how severe some Black patients' kidney disease is, and prevents them from getting transplants. Medical students and doctors have been trying to do away with race corre
"That Rotten Spot"
When the plague broke out in San Francisco in 1900 the public health department poured all of their energy into stopping its spread in Chinatown, as if Chinatown were the problem. This episode reveals why they did it, what it has to do with race science, and what it tells us about the history of public health.

Black Pills
In 2005 the FDA approved a pill to treat high blood preassure only in African Americans. This so-called miracle drug was named BiDil, and it became the first race-specific drug in the United States. It might sound like a good a good thing, but it had the unintended consequence of perpetuating the myth that race is a biological construct. Credits Hosts: Alexis Pedrick and Elisabeth Berry Drago Se
Bad Blood, Bad Science
The word "Tuskegee" has come to symbolize the Black community's mistrust of the medical establishment. It has become American lore. However, most people don't know what actually happened in Macon County, Alabama, from 1932 to 1972. This episode unravels the myths of the U.S. Public Health Service (USPHS) Syphilis Study (the correct name of the study) through conversations with descendants and hist
The African Burial Ground
In 1991, as crews broke ground on a new federal office building in lower Manhattan, they discovered human skeletons. It soon became clear that it was the oldest and largest African cemetery in the country. The federal government was ready to keep building, but people from all over the African diaspora were moved to treat this site with dignity, respect, and scientific excellence. When bioarchaeolo
Return, Rebury, Repatriate
In 2019, Abdul-Aliy Muhammad, a community organizer and journalist, learned that the Penn Museum of Archaeology and Anthropology had a collection of skulls that belonged to enslaved people. As Muhammad demanded that the university return these skulls, they discovered that claiming ownership over bodies of marginalized people is not just a relic of the past—it continues to this day.

The Vampire Project
In the 1990s a liberal population geneticist launched the Human Genome Diversity Project. The goal was to sequence the genomes of "isolated" and "disappearing" indigenous groups throughout the world. The project did not go as planned—indigenous groups protested it, and scientists and anthropologists criticized it. This episode examines what went wrong and asks the question: can anti-racist scienti
Keepers of the Flame
In the 1970s Barry Mehler started tracking race scientists and he noticed something funny: they all had the same funding source. One wealthy man was using his incredible resources to prop up any scientist he could find who would validate his white supremacist ideology—and make it seem like it was backed by a legitimate scientific consensus.

Calamity in Philadelphia
In 1793 a yellow fever epidemic almost destroyed Philadelphia. The young city was saved by two Black preachers, Richard Allen and Absalom Jones, who organized the free Black community in providing essential services and nursing the sick and dying. Allen and Jones were assured of two things: that stepping up would help them gain full equality and citizenship, and that they were immune to the diseas
BONUS EPISODE: Cheddar Man
In 2018 ancient DNA researchers revealed their analysis of a 10,000 year old skeleton called Cheddar Man. He was the oldest complete skeleton ever discovered in England, and the revelation that he had dark skin challenged assumptions many people had about what the earliest people in Britain looked like.
Origin Stories
It might seem as though the way we think about race now is how we've always thought about it—but it isn't. Race was born out of the Enlightenment in Europe, along with the invention of modern western science. And it was tied to the politics of the age—imperialism and later slavery. This episode traces the origins of race science to the Enlightenment, examines how the Bible influenced racial theori

Mechanochemistry
What comes to mind when you think of a chemistry lab? Maybe it's smoke billowing out of glassware, or colorful test tubes, or vats of toxic substances. Chemistry and hazardous solvents just seem to go hand in hand. But chemists like James Mack think there's a greener way: It's called mechanochemistry, a kind of chemistry that uses physical force to grind materials instead of solvents. And it's get

The Big 'What If' of Cancer
In this episode of The Disappearing Spoon, Sam Kean talks about Hermann Muller, a geneticist who in the 1920s discovered that radiation causes genetic mutations. This discovery happened around the same time that other geneticists were starting to link cancer with genetic mutations. Had both of these parties communicated they would have gotten a 50-year head start in cancer research. So why didn't
Disappearing Spoon: The Harvard Medical School Janitor Who Solved a Murder
On this episode of The Disappearing Spoon, Sam Kean talks about a murder mystery that rocked Boston in 1849. Harvard University alum and physician George Parkman had gone missing. The last place he was seen alive was at the Harvard medical building, which had plenty of bodies, but police couldn't find Parkman's there. That is until a janitor intervened and implicated a medical school professor. Th

In this episode of The Disappearing Spoon, Sam Kean breaks down the history of nitrocellulose. This thick, transparent liquid was the world's first plastic and could be shaped into anything, including billiard balls and photography film. With nitrocellulose film, you could run reels of pictures together quickly, which gave birth to the first movies. The only fatal flaw with this plastic is that it
History's First Car Crash Victim
In this episode of The Disappearing Spoon, Sam Kean talks about Mary Ward, a budding naturalist and astronomer from Ireland. She spent a lot of time observing plants and animals through a microscope and published a book of detailed sketches that dazzled readers and colleagues in the 1800s. However, her career was cut short by a strange curiosity of that time period: the automobile. They weren't th

In this episode of The Disappearing Spoon, Sam Kean talks about memory fugues, a psychological disorder that wipes out biographical information from people's brains. It is estimated that roughly 1 in 100,000 people seeking help for mental disorders have them. This disorder happens worldwide and it usually afflicts people in their 20s. Scientists have only recently started to piece together what is
How Climate Change Will Remake the Human Body
On this episode of The Disappearing Spoon, Sam Kean delves deep into the science behind the evolution of animal and human bodies. Like animals, human bodies have also evolved to adhere to the demands of ever-changing climates. This raises a question: how will human bodies respond to climate change?

The 'Mary Poppins' Cancer
In this episode of Disappearing Spoon, Sam Kean discusses the horrors of a particular genetic disease that was, literally, sweeping through London in the 1700s. In 1666, the Great Fire of London consumed about 13,000 homes and caused the modern equivalent about $1.3 billion in damage. After the Great Fire, London officials made chimneys mandatory in all homes and buildings. All these new chimneys
Disappearing Spoon: Kangaroo (and Pig and Monkey and Dog and Donkey) Courts
Animal trials have always been part of society, but we are not talking about the ones with lab mice. In medieval times dozens of animals were tried in human courts for committing human crimes. It sounds silly, but the practice raises an uncomfortable question that we are still grappling with today: if we hold animals accountable in court, doesn't that mean that they deserve some sort of legal prot

But Dickey is not interested in proving they are real; he is fascinated with
Ghost Hunting in the 19th Century
The 19th century was a time of rapid technological leaps: the telegraph, the steam boat, the radio were invented during this century. But this era was also the peak of spiritualism: the belief that ghosts and spirits were real and could be communicated with after death. Seances were all the rage. People tried to talk to their dead loved ones using Ouija boards and automatic writing. Although it mi

The Disappearing Spoon: The Anatomy Riots
In the 1700s human dissection was a big taboo—people feared that it would leave their bodies mangled on Judgment Day, when God would raise the dead. As a result, government officials banned most dissections. This led to some unintended consequences, most notably a shortage of bodies for anatomists to dissect. To meet the heightened demand, a new profession emerged: grave-robbers. These so-called r

The Death of the Lord God Bird
The ivory-billed woodpecker is sometimes called the Lord God bird, a nickname it earned because that's what people cried out the first time they ever saw one: "Lord God, what a bird." Even though the last confirmed sighting was in the 1930s, birders have been claiming they have seen the Lord God bird throughout the years, turning it into a myth. The sad part is it didn't need to be this way. And i
