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 frozen chicken patties a little grace?

Genetic engineering breakthroughs in the late 1960s and early 1970s came with a lot of promise—and peril too. Fears about what could happen with recombinant DNA experiments put scientists in the middle of a moral dilemma. Did they have a responsibility to consider how others might use their work? Or was their place simply to be on the lab bench? In this two-part episode, we’ll share the story about the first time scientists stopped and considered the ramifications of their work, with a self-impo...

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 with the FDA drug approval process, which takes years and even decades. This has created a tense situa...

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, as a result, re-wrote what’s known as “psychiatry’s bible”—the Diagnostic and Statistical Manual of M...

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 of Tumor Virology . Credits Host: Alexis Pedrick Senior Producer: Mariel Carr Producer: Rigoberto He...

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?

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 from weight loss, and now, our only problem seems to be getting enough of it for all the people who ...

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 "traffication," the history of road ecology, and what we can do about the problem.

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 gamechanger. “Nobody thought there could be a drug that would treat schizophrenia effectively,” say...

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 centers.

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 health benefits of colored light. So is there any validity to the claims of the past? Can color really ...

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 blue, did that mean they couldn’t see it? We treat color like it's a clear measure of whether or no...

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 down with Dr. Elle Lett who coined the term "health equity tourism" to describe when privileged and pre...

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 this harrowing statistic back to the dawn of American gynecology—a field that was built on the bodies...

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 correction tools once and for all. And they’re starting to see some success. About Innate: How Science In...

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.

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 bioarchaeologist Michael Blakey took over, that's exactly what they got. But it wasn't easy. Credits Host: Alexi...

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.

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.

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 disease. Neither promise turned out to be true.

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 theories, and considers how we still have a hard time letting go of the idea of race.

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 getting the attention of such huge corporations as Exxon Mobil. Still, some chemists are not ready to g...
