Distillations: Science + Culture + History

If you were around in the 1980s, you probably remember the lurking fear of an ominous hole in the sky. In the middle of the decade scientists discovered that a giant piece of the ozone layer was disappearing over Antarctica, and the situation threatened us all. The news media jumped on the story. The ozone layer is like the earth’s sunscreen: without it ultraviolet rays from the sun would cause alarming rates of skin cancer and could even damage marine food chains. And it turns out we were causing the problem. Today, more than three decades after the initial discovery, the ozone hole in Antarctica is finally on the road to recovery. How did we do it? This environmental success story gives us a glimpse into what happens when scientists, industry, the public, and the government all work together to manage a problem that threatens all of us.

They’re at the grocery checkout. They kill cancer cells. They’re in pointers that drive cats crazy and in the fiber networks that connect us to the internet. Lasers are so ubiquitous it’s hard to imagine a world without them. So you’d think we would know who the inventor was, right? Turns out it’s not so easy. There’s the guy who wrote down the initial idea, two other guys who got a patent for it, and then another guy who actually built the first laser. We spoke to Nick Taylor, author of Laser: The Inventor, the Noble Laureate, and the Thirty-Year Patent War about this story and what it tells us about how inventions happen.

Yoga pants are having a moment. And while they’re not new, they’ve moved beyond the gym and yoga studio into nearly every corner of our lives. This so-called athleisure wear trend has made a lot of people happy. “Once I wore [yoga pants], I never wore jeans again if I could help it,” says Sage Roundtree, a yoga instructor from North Carolina. But as comfy as the trend is, it has made a lot of people very unhappy—including the entire cotton industry. That’s because performance athletic wear isn’t made out of cotton. It’s made of synthetic fibers such as Lycra, polyester, and spandex. As demand for athleisure wear grows, demand for cotton shrinks. Luckily, cotton has a few tricks up its sleeve to keep consumers interested—because this is only the latest episode in a decades-long rivalry between cotton and synthetic fibers.

Every aspiring chemist has heard of Boyle’s law—the equation that relates the pressure of a gas to its volume. But even if you know about Robert Boyle himself, it’s not likely you’ve heard of his sister, even though she probably talked him through many of his ideas. Katherine Jones, Lady Ranelagh (1615–1691), had a lifelong influence on her famous younger brother, natural philosopher Robert Boyle. In her lifetime she was recognized by many for her scientific knowledge, but her story was almost lost to time. This episode is a collaboration with Poncie Rutsch, the creator and host of Babes of Science. Poncie interviewed CHF’s own Michelle DiMeo, a historian who’s writing a book about Lady Ranelagh. Babes of Science is a podcast that tries to answer two questions: Who are the women who changed the trajectory of science? And why has it taken us so long to recognize their work?

As you ponder which shiny new gadgets to put in your children’s stockings this holiday season, beware of the story of the Abbott family, whose lives were forever changed after a little too much screen time. Distillations brings you a live performance of Ray Bradbury’s short story “The Veldt.” Originally titled “The World the Children Made,” it’s a science-fiction tale about the dangers of our growing overdependence on technology. “People ask me to predict the future when all I want to do is prevent it,” Bradbury said. “We have too many cellphones. We’ve got too many internets. We have got to get rid of those machines.” Special thanks to Mechanical Theater and the Hear Again Radio Project for the live performance.

It’s one of the most bizarre episodes in American food history: when butter and margarine were at war. What you choose to spread on your toast might seem like a boring subject, but it turns out to be fascinating and sometimes hilarious. Margarine’s history began with French emperor Napoleon III, a French chemist, and some sheep’s stomachs, and went on to include heated courtroom debates, our first federal laws regulating food, and outlaws smuggling faux butter across state lines. The spreads have competed for more than a hundred years, and public preferences shift each time our understanding of health science changes. In this episode of Distillations we learn about the history of butter and margarine and explore the distinctly American debates they inspired involving food, health, science, and regulation.

Baby horses and giraffes walk soon after they’re born, and they can feed and take care of themselves pretty quickly, too. A one-year-old person, on the other hand, is basically helpless. But humans go on to live much longer than most other mammals, and scientists have long been trying to piece together why this is the case. One theory, called the grandmother hypothesis, claims that grandmas are the key to why humans live so long. Unlike most other species, human females live long past their childbearing years and so can help raise their grandchildren, allowing their daughters (or daughters-in-law) to have another baby before the first one can take care of itself. As warm and fuzzy as this idea sounds, it turns out to be pretty controversial. In this episode of Distillations we explore the grandmother hypothesis and find out what the debate is all about.

Though they lived decades apart, Adolphe Dessauer and Abdelwahhab Azzawi share similar stories. They were both esteemed physicians who faced violence and persecution in their home countries. They both sought refuge abroad and found safety, only to find themselves facing a new struggle—getting permission to practice medicine in their new homes. Dessauer, a Jewish doctor, fled Germany for the United States in 1938. Azzawi, a 36-year-old ophthalmologist from Syria, found asylum in Germany in 2015. Both men’s lives were spared through the generosity of their new countries, but they had to struggle to give back in the most meaningful way they could—by sharing their medical expertise. In 2016 every American Nobel laureate in science was an immigrant. And it wasn’t just that year; U.S. winners often are born abroad. Yet as global an enterprise as science has become, navigating bureaucracy and straddling boundaries seems to be as difficult in the 21st century as during World War II.

There are no parents in the world who want to see their child sick. Often the illness is no big deal—you follow doctor’s orders and your kid gets better soon. But what do you do when your child is really sick, and it’s because of decisions the founders of your religion made more than 300 years ago? And what do you do when the medical solutions seem to run counter to that very same religion? This is the dilemma faced by many Amish and Mennonite parents in Lancaster County, Pennsylvania, whose children suffer from genetic diseases at rates exponentially higher than the rest of the population. These Plain People, as they call themselves, typically eschew technology. But 30 years ago they chose to step out of character and embrace the latest advances in genomic medicine to help save their children. Reporter Kyrie Greenberg spent almost a year getting to know some of these families, and she produced this podcast with us.   Credits Hosts: Michal Meyer and Bob Kenworthy Producer: Mariel Carr Associate Producer: Rig

On April 22, 2017, more than one million people in 600 cities around the world took to the streets in the name of science. Many were scientists themselves, and quite a few donned lab coats. Some were protesting for the first time. It was an unusual sight perhaps, but science has never been immune to politics. “If we could imagine angels doing science maybe it wouldn’t be political,” says Liz Lopatto, science editor of the technology site the Verge, “But since it’s humans, it’s inescapable.” Throughout the past century quite a few scientists have taken up political causes, but the tide of politics and science ebbs and flows, from the labs to the streets and back again. Now, after a period of relative quiet it seems to be flowing again. But this time it’s different. Sociologist Kelly Moore says, “I don’t know of any period in American history when scientists have felt the need to collectively defend science as a public good.” Show Clock 00:32 March for science 02:14 Science as a noun, science as a verb  04:55 

There was a time when tattoos were taboo, and you thought long and hard before getting one. Today 20 percent of American adults are inked. Tattoos just don’t carry the stigma they once did—unless it’s a particular kind of tattoo, in a particular place on the body. Fortunately, as our penchant for getting tattoos has grown, so has our ability to get rid of them. In the 1960s researchers started experimenting with lasers to remove tattoos, and since then the technology has dramatically improved. Now we can erase our past, whether it’s a sailor’s bad decision from overseas or a gang identifier that prevents its owner from getting a job—and could even get him killed. Sociologist and CHF research fellow Joseph Klett traces the modern history of tattoo removal through the stories of his father—a retired sailor—and ex-gang members in California.   Credits Hosts: Michal Meyer and Bob Kenworthy Reporter: Joseph Klett Producer:  Mariel Carr Associate producer: Rigoberto Hernandez Additional production by Kyrie Greenber

Most of us are content to use our existing five senses to see, hear, smell, taste, and touch our way through the world. But an increasing number of people called biohackers are not satisfied with watching the everyday brilliance of a sunset or petting a silky kitten. They want infrared vision and electromagnetic fingertips. “Why wouldn't I want to add one more sense to the ones I already have and enjoy so much? The ability to feel just a little bit more?” Nic Fox asked reporter Catherine Girardeau. Fox has a device embedded in his chest that vibrates when he faces magnetic north. To understand more about these would-be cyborgs we turned to Kara Platoni, author of We Have the Technology: How Biohackers, Foodies, Physicians and Scientists Are Transforming Human Perception, One Sense at a Time. Platoni is a science reporter and a lecturer at University of California, Berkeley’s Graduate School of Journalism. She describes how many biohackers feel the future hasn’t gotten here fast enough. They’re ready to be cyb

For as long as humans have been around they’ve worried about their smell. “That’s why we’ve had perfumes for as long as we’ve had people,” says Cari Casteel, a CHF research fellow studying the history of deodorant. But, Casteel says, "it wasn't until the late 19th, early 20th century that the technology and the chemistry catches up to what people want." Today most Americans don’t give a second thought to using deodorant. In fact, some 90% of the population slathers the stuff on. But in the late 19th and early 20th centuries deodorants and antiperspirants were new, and their makers had to convince potential customers (all women) that perfumes alone weren’t cutting it and that their body odor and perspiration were unacceptable. They did so by preying on women’s insecurities, an approach later used successfully on men. In this episode we explore some of the funny, disturbing, sexist, and quirky advertisements from deodorant’s history and discover that today’s commercials are strangely similar to those of the pas

We all know hydration is important to health, but many people find water boring to drink. Juice and Coke aren’t boring, but they aren’t very healthy either. One way to transform water into a more exciting drink is to add bubbles. For centuries carbonated water from natural springs was used as a medicine. Now lifestyle and health concerns have combined to drive fizzy water’s renewed popularity. Join us as we unpack the long history of carbonated water, from natural mineral springs, to the invention of artificial carbonation by a radical 18th-century chemist, to the fading tradition of seltzer deliverymen in New York City.

The sports bra is omnipresent in today’s sports landscape. But the current iteration of this nifty item is less than 40 years old, and it arrived with a serendipitous origin story. For this episode of Distillations we talked to Lisa Lindahl, an entrepreneur from Vermont, who in 1979 patented what was to become the modern-day sports bra. It’s a story about a runner who wanted running to be more comfortable. “It was the right product at the right time. It really struck a chord for so many women,” says Lindahl. “This product came into being because it was something I wanted.” We also talked to our museum team about their new exhibition, Second Skin: The Science of Stretch, and the roles stretch fabrics play in health and sports. Christy Schneider, exhibits project manager at the Museum at CHF, says it’s all about getting the body you want, whether you want to dance all night or run a marathon. “How do you that?” asks Schneider. “You clothe it in a second skin.” Show Clock 00:05 Intro00:32 ‘The Sports Bra Seen Ro

Our producer is pregnant. For the past nine months people have asked what her birth plan is, which to her seems like asking what kind of weather she had planned for her wedding day. “All of a sudden my life was full of these terms: natural, medicated, doula, epidural, and it quickly became clear that there was a great debate—and I was supposed to choose a side.”  We wanted to know when this controversy started, and why comedian Amy Schumer is joking about sea-turtle births. So we talked to Lara Freidenfelds, a historian of sexuality, reproduction, and women’s health in America, and learned some surprising things about our nation’s early childbirth practices. Freidenfelds also shared her views about why a growing number of women are opting for unmedicated births, while Amy Tuteur, a retired obstetrician and the author of Push Back: Guilt in the Age of Natural Parenting, tells us that once upon a time all births were natural—and a lot of mothers and babies died.

Over the past year we’ve brought you stories about tacos, taxidermy, and DDT. But at the same time we’ve been thinking about and researching medicine—specifically, how outsiders to the field have helped change the ways doctors practice. Join us to find out how philosophers, transgender patients, and Jehovah’s Witnesses have influenced health care in the United States over the past few decades.  Show Clock 00:04 Intro 01:41 Transgender and intersex patients 06:51 Bioethicists 09:55 Jehovah's Witnesses Credits Hosts: Michal Meyer and Bob Kenworthy Guest: Mariel Carr Producer: Mariel Carr Associate Producer: Rigoberto Hernandez Music "Nature Kid" by Podington Bear, courtesy of the Free Music Archive.

Have you noticed any antlered rabbits mounted on the wall of your local coffee shop? Or maybe some geese with butterfly wings? That’s because taxidermy has made a comeback. Our producer, Mariel Carr, wanted to know why, so she spent a few months exploring the alternative—or rogue—taxidermy scene in Philadelphia. Rogue taxidermy takes an artistic approach to the traditional craft. It combines materials, and even animals, in unconventional ways. And it seems to involve a fair amount of glitter. Meet Beth Beverly, a young taxidermist; John Whitenight, an eccentric collector of Victorian taxidermy; and the polar bears and gorillas at the Academy of Natural Sciences. Together they explain taxidermy’s long history of combining art and science, and describe the role arsenic played in taxidermy’s rise to prominence in the 19th century.

We’re guessing you know who Albert Einstein and Isaac Newton are, and maybe you’re even familiar with Linus Pauling or Roald Hoffmann. But it turns out that a lot of people can’t name a single female scientist besides Marie Curie. Exasperated by this fact, radio producer Poncie Rutsch made a podcast she titled Babes of Science. The show profiles accomplished scientists from history who also happened to be women. We became such fans of the show that we decided to create a special Babes of Science and Distillations collaborative episode. In it Rutsch profiles Barbara McClintock, a cytogeneticist who discovered transposons, or “jumping genes,” and whose radical ideas made it hard for her to gain acceptance in the field.

When you bite into a taco, quesadilla, or anything else involving a traditionally made corn tortilla, your taste buds get to experience the results of an ancient chemical process called nixtamalization. The technique dates to around 1500 BCE and involves cooking corn kernels with an alkaline substance, like lime or wood ash, which makes the dough softer, tastier, and much more nutritious. Only in the 20th century did scientists figure out the secret of nixtamalization—the process releases niacin, one of the essential B vitamins. Our guest, archaeologist and nixtamalization expert Rachel Briggs, says that the historical chemical process transformed corn from a regular food into a viable dietary staple, one that cultures around the world continue to rely on for many of their calories. Without nixtamalization Mesoamerican civilizations like the Maya and the Aztec would not have survived, let alone flourished. Benjamin Miller and Christina Martinez are the only chefs in Philadelphia making their tortillas from sc
