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 give up their traditional techniques. “I thought they were married to the molecules,” says Mack, who is pictured above placing vials into a machine that uses fast-spinning ball bearings to pulverize molecules. “Little did I know they were actually married to the flask.”   Credits Host: Elisabeth Berry Drago Reporter, Producer, and Audio Engineer: Jonathan Pfeffer Senior Producer: Mariel Carr Producer: Rigoberto Hernandez Associate Producer: Padmini Raghunath

Each episode of Distillations podcast takes a deep-dive into a moment of science-related history in order to shed light on the present.

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 previously unengaged scholars enter the health equity field without developing the necessary expertise.

Exploring 'Health Equity Tourism'

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 of enslaved women. And we’ll meet eight women who have dedicated their lives to understanding and solving this complex problem.

The Mothers of Gynecology

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 Invented the Myth of Race “Correcting Race” is Episode 9 of Innate: How Science Invented the Myth of Race, a podcast and magazine project that explores the historical roots and persistent legacies of racism in American science and medicine. Published through Distillations, the Science History Institute’s highly acclaimed digital content platform, the project examines the scientific origins of support for racist theories, practices, and policies.

Correcting Race

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.

"That Rotten Spot"

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 Senior Producer: Mariel Carr Producer: Rigoberto Hernandez Associate Producer: Padmini Raghunath Audio Engineer: Jonathan Pfeffer “Innate Theme” composed by Jonathan Pfeffer.
