Distillations: Science + Culture + History

Everyone knows blood is powerful. The ancient Greeks realized it, Jesus understood it, Dracula certainly recognized it, and your doctor still knows it today. And everybody knows, says hematologist and historian of medicine Jacalyn Duffin, that if we lose a lot of blood, we’re going to die. Jehovah’s Witnesses’ beliefs have led them to refuse blood transfusions—to the consternation of many inside the medical profession. But the religious group still wants medical care, says reporter Alex Ashley, and their advocacy has helped propel a new movement in medicine in which doctors perform surgeries without transfusing blood. Remarkably, it has turned out better for everyone, suggesting that religion and medicine might be less at odds than they sometimes seem.

Scientists experimented with skin and organ transplants for a long time before they finally met with success in the mid-20th century. Now surgeons are expert at performing transplants. The only problem? There aren’t enough organs to go around, which creates some serious ethical dilemmas. First, reporter Dalia Mortada takes us to Tel Aviv, Israel, where a dialysis patient waiting for a new kidney is running out of patience. Conflicting religious interpretations have prevented many Israelis from signing up to become organ donors. This has created a serious supply-and-demand problem, leading many desperate patients to the black market. Mortada tells us how this trend is slowly changing and talks to the doctors, rabbis, and bioethicists behind the shift. Then we talk to American bioethicists Art Caplan and Robert Baker about the pitfalls of the U.S. donation system. “You sign up when you go to Motor Vehicles,” Caplan says, “which may not be the ultimately wonderful place to make [these] decisions, other than the

Americans have had a long, complicated relationship with the pesticide DDT, or dichloro-diphenyl-trichloroethane, if you want to get fancy. First we loved it, then we hated it, then we realized it might not be as bad as we thought. But we’ll never restore it to its former glory. And couldn’t you say the same about America’s once-favorite pop star? We had a hunch that the usual narrative about DDT’s rise and fall left a few things out, so we talked to historian and CHF fellow Elena Conis. She has been discovering little-known pieces of this story one dusty letter at a time. But first our associate producer Rigoberto Hernandez checks out some of CHF’s own DDT cans—that’s right, we have a DDT collection—and talks to the retired exterminator who donated them.  Show Clock: 00:03 Introduction01:26 DDT's Rise06:56 DDT's Fall13:24 DDT's Complicated Legacy  Credits: Hosts: Michal Meyer and Bob KenworthyGuest: Elena ConisProducer: Mariel CarrAssociate Producer: Rigoberto Hernandez Music: Music courtesy of the Audio Net

2015 was a good year for outer space. Star Wars: Episode VII came out, NASA started hiring astronauts again, SpaceX successfully launched and returned a rocket, and the U.S. Congress passed the SPACE Act of 2015—a bill that gives any American who extracts resources from an asteroid legal rights to the bounty they reap. Since no one has yet mined an asteroid this legislation might seem premature, but it’s essential to the future of two Silicon Valley asteroid mining companies. That’s right, they already exist. They’re just waiting for humans to start colonizing space. Reporters Katie Gilbert and Annie Costakis talk to Daniel Faber, the founder of Deep Space Industries, about his dream: to build the space equivalent of Home Depot, as well as fueling stations and manufacturing plants. They also explain a few of the untested theories behind asteroid mining. We wanted to know more about the history of space dreaming and space colonies, so we talked to Patrick McCray, a historian of science and technology and the a

Several years ago historian of medicine Alice Dreger found herself in a room full of intersexed people, individuals with reproductive or sexual anatomy that is neither typically female nor male. Dreger noticed something strange: many of them had teeth that were in bad shape. She soon learned that many of them had endured such traumatic experiences with doctors that they wouldn’t go near anyone in a white coat, including dentists. We were astonished by this story, so we asked Dreger to tell us more. She joined us for our December podcast alongside Eric Vilain, a medical geneticist and director of the Center for Gender-based Biology at UCLA. While intersex, transgender, and transsexual issues have recently entered the mainstream, our guests explain that there have always been those whose anatomy or identity prevents them from fitting neatly into the categories of male or female. And even with this newfound exposure, tensions continue to exist for them all. But first we’ll hear about the experiences of a transge

Hackers. Spies. Secrets. This is the menacing language of industrial espionage. But how easy is it to plunder a company for its ideas? Not very, says our guest, Douglas O’Reagan, a historian of science and technology. Throughout history, O’Reagan argues, stealing trade secrets has proven more complicated than lifting a blueprint or section of computer code. What makes a company successful is usually much harder to grasp. But first we look at how one company is trying to pass on the skills and secrets responsible for its success. Reporter Susanne Gietl visits the small Bavarian town of Ingolstadt, headquarters of German automaker Audi. There she finds hundreds of Mexican workers learning skills, secrets, and the “German way” to build cars so they can bring that knowledge back to Mexico. Join us for a trip to the murky world of technology transfer.

Celebrities, politicians, and scientists have fiercely debated the safety of using genetically modified organisms, or GMOs, in food. It remains to be seen whether GMO labeling becomes mandatory in the United States, but there’s no doubt that the “GMO-free” sticker is garnering the prestige and premium prices already reaped by the labels “organic” and “gluten-free.” But what’s the big fuss? And how did this great GMO debate begin?To find out Distillations goes to the soy and corn fields of Iowa where reporter Amy Mayer hears the perspectives of a few Midwesterners, including two farmers who have found a lucrative niche for the GMO-free crops they’re growing. Then, we’ll talk with plant geneticist Pamela C. Ronald and organic farmer Raoul Adamchak. Together they wrote Tomorrow’s Table: Organic Farming, Genetics, and the Future of Food. And they’re married—to each other.

Ten years ago Hurricanes Katrina and Rita tore into the Gulf Coast and displaced more than one million residents. For many of these people, trailers provided by the Federal Emergency Management Agency became their homes. But many of the new occupants soon found it hard to breathe, suffering flulike symptoms, stinging eyes, and nosebleeds. The culprit was formaldehyde, which emanated from the hastily assembled, substandard materials used to make the trailers. A decade after the storms Distillations follows CHF researcher and medical anthropologist Nick Shapiro as he searches for the remaining FEMA trailers. His search takes him to the oil fields of North Dakota, where a different kind of housing crisis is taking place.    

Most of us are familiar with the achievements of Galileo and Newton, but who were their peers? And what was it like to practice science in the 16th and 17th centuries? Come geek out with us as we travel back in time and explore what the world was like when science and the supernatural were not so far apart. We talk to two historians of science, Deborah Harkness and James Voelkel. Harkness is the author of The Jewel House: Elizabethan London and the Scientific Revolution as well asthe All Soul’s Trilogy, a popular fantasy series filled with witches, vampires, demons, scientists, and historians. Voelkel is the curator of rare books at CHF and an expert on Johannes Kepler, a 17th-century astronomer, mathematician, and astrologer.   Though we were unable to time travel for this show (much to our dismay), we did get to visit the Making and Knowing Project’s laboratory at Columbia University, where a group of historians of science are reconstructing a 16th-century workshop and re-creating recipes from an anonymous

This is Distillations’s 200th episode, and we’re celebrating! We pored through hundreds of shows and pieced together some of the funniest, grossest, and most surprising moments in Distillations history. Still chuckling from episode 166, "Alchemy After Dark," where CHF’s rare book curator Jim Voelkel cries from laughter while reading a steamy alchemical passage from yesteryear? Still trying to forget the body-cheese experiment from episode 156, "Hard to Stomach"? Or maybe you’re still perplexed about how a Viagra tablet might wind up in your herbal supplement, as explained in episode 197, "Fads and Faith"? We visit these moments and many more. Thanks for listening, and we hope you’ll join us for the next 200 shows!  CREDITS: Hosts: Michal Meyer and Bob Kenworthy Producer & Editor: Mariel Carr   Music courtesy of the Audio Network.   

Mother Nature can do a lot of damage. Tornadoes, hurricanes, floods, and droughts destroy landscapes and ruin lives. But what happens when humans are the ones creating these disasters? This episode of Distillations explores the many ways humans have provoked nature’s destructive forces purposefully and inadvertently through history. Our journey begins in Oklahoma, a state that now has more earthquakes than California. Reporter Anna Stitt talks to the people affected by these new quakes and finds out how their lives have changed. Then we talk to historian Jacob Darwin Hamblin about his latest book, Arming Mother Nature: The Birth of Catastrophic Environmentalism. He tells us how Cold War military planners sought to use the environment as a weapon and in the process discovered how vulnerable our planet really is.

The early days of neuroscience relied on tragedy to strike—a rabies infection, a botched lobotomy—before doctors could peek inside the brains of humans. Today advanced technology, such as the functional MRI, helps scientists study brains (and healthy ones at that) far more easily. The revelations they’re making call into question conventional ideas of maturity and our capacity for free will. The story begins at a unique laboratory at Michigan Technological University, called the Mind Music Machine, where reporter Allison Mills talks to a cognitive scientist who’s trying to develop technology that can interpret our emotions.  Then we talk about the history of neuroscience with Sam Kean, a regular contributor to Distillations magazine and author of the recent book The Tale of the Dueling Neurosurgeons. Frances Jensen, a neuroscientist and author of The Teenage Brain, brings us into the present and explains the science behind why teenagers drive their parents crazy.

In 2014 the United States had 650 reported cases of measles, a disease made preventable by a vaccine introduced 30 years ago. The majority of these measles victims were children whose parents chose not to vaccinate them.  Meanwhile at least 85,000 dietary supplements line the shelves of GNC and other “big box” chains, as well as smaller health food stores. Even though the FDA cannot assure the safety or effectiveness of any of these products before they're sold, they enjoy widespread popularity in the United States. This episode of Distillations explores what connects these two issues. Our journey starts in Shanghai, where reporter Rebecca Kanthor investigates a strange fashion trend among pregnant women—a special apron meant to protect its wearers from the harms of electromagnetic radiation. Then we talk with Paul Offit, an infectious disease pediatrician at Children’s Hospital of Philadelphia and author of Bad Faith: When Religious Belief Undermines Modern Medicine, and Catherine Price, author of Vitamania

Some technologies flash in the pan so quickly they hardly leave a trace (Google Glass anyone?); while others seem to stick around long past their use by date. And still other creations appear to be gone for good, only to make a comeback within a niche—and likely nostalgic—community. We set out to explore the rhymes and reasons behind these ebbs and flows of technological innovation and obsolescence. First we go to a place where digital nostalgia is alive and well: a vintage video arcade outside of Chicago. Reporter Colleen Pellissier tells the story of one man who dedicates his life to keeping these old and cranky machines running. Then we talk to Ben Gross, a historian of technology and a fellow at CHF. He shares his love of the long-forgotten video disc and explains why nothing is obvious when it comes to the successes and failures of technologies.

In case you hadn’t noticed, during our short time on Earth we humans have created a lot of stuff. Some of it is life-altering, like the device you’re looking at right now, and some of it is pretty silly, like those plastic, banana-shaped containers made for holding bananas. Regardless of their value, these objects all have one thing in common: one day they will become trash. For all the time we spend creating these wonders, we don’t devote much energy to thinking about what happens when their intended life-cycles run out. This episode of Distillations traces the history of trash, consumerism, and municipal garbage collection in the United States, and explores what the future holds. First, reporter Daniel Gross tells us the origin story of kitty litter, an ingenious consumer product that transformed a natural resource straight into trash. Then we talk with Carl Zimring, an American environmental historian and Associate Professor of Sustainability Studies at the Pratt Institute in Brooklyn, New York. He describ

Thirty years ago an HIV diagnosis was a death sentence. Today, sophisticated drug cocktails known as highly active antiretroviral therapy, or HAART, have dramatically changed the fates of people with the disease. They can now live with a chronic manageable disease instead of dying from a fatal one. Yet in many ways we’re treading water: each year the U.S. sees around 50,000 new HIV cases, and estimates show that 20-25% of these people don’t know they’re infected. And, while the drugs are effective, many people throughout the world can’t afford them. So should we consider our response to HIV a complete success story? This episode of Distillations tries to find the answer. Our journey begins in San Francisco’s Castro District, the epicenter of the city’s HIV epidemic in the 1980s. Reporter Andrew Bowen talks to AIDS activist Tez Anderson, who started an organization to combat AIDS Survivor Syndrome. Then we talk to Dr. Mark W. Kline and Andrew P. Rice, a physician and a virologist who have been working on HIV s

At the beginning of the 19th century women in the United States had an average of seven or eight children. By 1900 they had only three or four, and today 35% of Americans have exactly two children. How did this happen? This episode of Distillations explores the role technology has played in reproduction, and how it has affected the ethical and moral landscape that surrounds it. First, reporter Allison Quantz talks to her sister to find out what she plans to do with her extra frozen embryos. Along the way Quantz learns that there are more than one million frozen embryos in the United States with similar uncertain futures. Then we talk with Deanna Day, a historian of medicine and technology and a post-doctoral fellow at CHF, and Lara Freidenfelds, a historian who writes about women’s health, sex, and reproduction in America.

Chemical weapons have played a chilling role in human history, ever since they were first used in World War I.  As reports of more recent use continue to cycle through the news, we decided to take a deeper look.  We wanted to understand why chemical weapons were created in the first place, the ethical dilemmas inherent in their use, and the complicated process of getting rid of them. The story begins in Belgium, where reporter Helena de Groot visits a farm in Flanders Fields—the frontline during World War I—and discovers that for some people the war isn’t yet over. Then we talk to Jeffrey Johnson, a historian of science and technology at Villanova University with a special interest in the origins of chemical warfare, and Amy E. Smithson, a senior fellow at the James Martin Center for Nonproliferation Studies, who specializes in modern-day chemical and biological weapons and their proliferation. Our guests discuss the past and present of chemical weapons, and share their thoughts about the future of warfare. S

If you asked people which of their senses they most feared losing, they'd probably say sight or hearing. But what about the ability to smell? This episode of Distillations examines what is perhaps our most underrated sense, and ponders what life would be like without it. We hit the streets of South Philadelphia to understand how a pervasive odor troubled neighborhood residents in the summer of 2014. Then we hear the story of Mario Rivas, a man who has lived his whole life without a sense of smell, and the great lengths he went to gain one. Then, we'll talk to two smell experts, Pamela Dalton, a psychologist at the Monell Chemical Senses Center in Philadelphia, and David Barnes, a professor of the history of medicine and public health at the University of Pennsylvania. Our guests discuss the connection between smelling, odors, and emotions, as well as the history of odors, germs, and public health crises.

Where can you find a teacup, the molar of a goat, and an arrowhead all in one place? At an urban archaeology site, that’s where. This episode of Distillations goes underground, and reveals the fascinating worlds beneath our city shoes. First, we visit an artifact processing lab where volunteers are dusting off thousands of objects from a historic street in Philadelphia. Then we stop in on an excavation site alongside Interstate 95. Then, we'll talk to Doug Mooney, a senior archaeologist at URS corporation and the president of the Philadelphia Archaeological Forum, and Deirdre Kelleher, an archaeologist finishing her doctorate at Temple University. They describe their experiences with public archaeology, debunk a few of the field’s myths (no dinosaurs here, folks) and describe the unique process of digging in cities.
