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 stoppe...

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, w...

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.

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...

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, ...

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 Th...

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 i...

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. 

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.

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 th...

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 t...

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.

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. 

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 historians.

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...
