First up on the podcast, the Bering Sea's snow crabs are bouncing back after a 50-billion-crab die-off in 2020, but scientists are racing to predict what's going to happen to this important fishery. Contributing Correspondent Warren Cornwall joins host Sarah Crespi to discuss what's next for snow crabs. Next on the show, freelance producer Elah Feder talks with Fei Peng, a professor in the department of psychology in the School of Public Health at Southern Medical University in Guangzhou, China, and principal investigator at the Great Bay Area Brain Science and Brain Inspired Research Center, about detecting emotions—or more scientifically “affect”—in bumble bees. His group observed how a bumble bee that appears to be hopeful can share this state with other bees. This week's episode was produced with help from Podigy.

First up on the podcast, Contributing Correspondent Kai Kupferschmidt takes a trip to Svalbard, an Arctic archipelago where ancient RNA viruses may lie buried in the permafrost. He talks with host Sarah Crespi about why we only have 100 years of evolutionary history for viruses such as coronavirus and influenza, and what we can learn by looking deeper back in time. Next on the show, Nathalie Stroeymeyt, senior lecturer at the School of Biological Sciences at the University of Bristol, joins freelancer producer Elah Feder to talk about how humans aren't the only species that takes public health measures to stop outbreaks. To keep their colonies healthy when threatened with infectious disease, ants socially distance and even make architectural changes to their nests' organization.

We have a favor to ask! We want to know more about what you like, what you don't, and who you are—it'll help us make better episodes of Science Diction. Please, take our brief survey. Thank you! At the turn of the 20th century, the American chestnut towered over other trees in Eastern forests. The trees would grow as much as 100 feet high, and 13 feet wide. According to legend, a squirrel could scamper from New England to Georgia on the canopies of American chestnuts, never touching the ground. And then, the trees began to disappear, succumbing to a mysterious fungus. The fungus first appeared in New York City in 1904—and then it spread. By the 1950s, the fungus had wiped out billions of trees, and effectively finished off the American chestnut. Now, some people are trying to resurrect the American chestnut—and soon. But not everyone thinks that's a good idea. Guests: Sara Fitzsimmons is Director of Restoration, North Central Regional Science Coordinator, and Regional Science Coordinator Supervisor at the American Chestnut Foundation. Susan Freinkel is the author of American Chestnut: The Life, Death, and Rebirth of a Perfect Tree. Neil Patterson Jr. works at the Center for Native Peoples and the Environment at SUNY, and is a member of the Tuscarora Nation.

In 2014, a grad student in Kolkata named Ujaan Ghosh came across an old book by a Scottish missionary. And as Ghosh paged through the book, he noticed the missionary kept using a word over and over: Juggernaut. But the missionary wasn't using it the way we do today—to mean an unstoppable, overwhelming force. He was using it to talk about a place: a temple in Puri, India. So Ghosh dug further, and as he grasped the real story of where the English word, juggernaut, had come from, he realized there was just no way he could keep using it. A transcript of this episode is being processed and will be available within a week. Guests: Chris Egusa is an audio producer and 2020 KALW Audio Academy fellow.

This episode is a re-broadcast. It originally aired in November 2020. Every year, the World Meteorological Organization puts out a list of 21 names for the season's hurricanes and tropical storms. But in 2020, the Atlantic hurricane season was so active that by September, we'd flown through the whole list of names and had to switch to the Greek alphabet. Thus, Hurricane Iota became the 30th named storm of the season. We've only had to dip into the Greek alphabet once before, in 2005. But the practice of naming hurricanes goes back to the 19th century, and it was a bumpy ride to land on the system we use today. In this episode: The story of a meteorologist in Australia, a novel, and a second-wave feminist from Florida—and how they brought us hurricane names. Guests: Christina M. Gonzalez is a doctoral candidate in anthropology at the University of Texas at Austin.Liz Skilton is a historian and the author of Tempest: Hurricane Naming and American Culture.

If you're one of the 2 million people who take the Myers-Briggs Type Indicator every year, perhaps you thought Myers and Briggs are the two psychologists who designed the test. In reality, a mother-daughter team created the test essentially at their kitchen table. In this episode, we look at the unlikely origins of the Myers-Briggs, going all the way back to the late 1800s when Katharine Cook Briggs turned her living room into a “cosmic laboratory of baby training” and set out to raise the perfect child. In this three-part series, we uncover the strange history of the most popular personality test in the world, and how two women revolutionized personality testing—for better or for worse.

Last month, Science Diction received a letter from a listener named Ben. He wanted to know about ambergris, a strange substance that washes up on beaches from time to time. So today, we’re talking about this thing that for centuries, rich people coveted, rubbed on their necks, and even ate, all without having any idea what it really was. If they had known, they might have put their forks right down. Plus, Science Diction now has a phone number! If you, like Ben, want us to cover a certain word, you can call in, leave us a message, and we might play it on the show. Call 929-499-WORD or 929 499 9673.

When the first COVID-19 vaccines were approved for emergency use last December, it felt like - at last! - our nightmare was nearly over. Then came reports of botched distribution efforts, from broken websites to factory mix-ups. Scientists created the vaccine in record time, but it was beginning to look like that might’ve been the easy part. But if you think vaccine distribution was a logistical nightmare in 2021, try doing it in the early 1800s. In 1796, Edward Jenner discovered that cowpox worked as a vaccine against smallpox. All you had to do was pop a cowpox sore on someone’s skin and transfer the lymph fluid (a.k.a. pus) into a cut on a second person. Soon, they'd develop a few sores, but when they recovered, they'd be immune to smallpox, a far more serious disease. This worked well enough for short distances, but when smallpox began to destroy Spanish colonies in the Americas, Spain had to figure out a way to move the vaccine across the ocean. Their solution was resourceful, effective, and very ethically dubious. Science writer Sam Kean brings us the story of the world's first vaccination campaign. Guest: Sam Kean is a science writer, author of The Bastard Brigade, and host of the podcast Disappearing Spoon. Footnotes & Further Reading: Listen to our episode on the origin of the word ‘vaccine.’ Listen to a full episode about this story on Sam Kean’s podcast, Disappearing Spoon.

Science Diction from Science Friday is back! Their latest episode is all about a recent buzzword: "Introvert." In 2013, introverts staged their comeback. For decades, they’d been told to get out of their shells and *smile*, while those showy, gregarious extroverts were held up as the American ideal. But when one author published a kind of introvert’s manifesto, she sparked an introvert pride movement. Since then, the war of the ‘verts has only escalated, with self-identified introverts accusing extroverts of being shallow and incessantly chatty party monsters, and extroverts declaring introverts self-absorbed shut-ins who are just jealous because extroverts are actually happy. (A contention that studies support.) It all feels like a very 21st Century, internet-era drama. But the history of the dubious and divisive introvert-extrovert binary began 100 years ago, when Carl Jung fell out with Sigmund Freud, and tried to make sense of where they’d gone wrong. In the process, Jung coined a couple of new terms, and unleashed an enduring cultural obsession with cramming ourselves into personality boxes.

Wiebke Bleidorn is a professor of psychology at the University of California Davis. Kelly Egusa is producer Chris Egusa’s sister, and a proud introvert.

In 1953, in the coastal town of Minamata in Japan, locals noticed some cats were acting strangely—twitching, spinning in circles, almost dancing. The reality was far darker. What looked like dancing was really convulsions. The cats drooled, spun in circles, and flung themselves into the sea. The cause of this strange behavior, residents discovered, was mercury. Mercury—a silvery liquid, named for a quick-footed Roman God—has captivated humans since ancient times. It’s found in Egyptian tombs that date to 1500 BCE, and the first emperor of unified China believed it was the elixir of life. But what happens when it invades a town, and seeps into our brains? Footnotes & Further Reading: For this story, we relied heavily on the book Minamata : Pollution and the Struggle for Democracy in Postwar Japan.Learn how mercury played a pivotal role in pinpointing a key campsite location in the Lewis and Clark expedition.

When Is It Time To Say Goodbye? Imagine you’re having a conversation with someone. You may get the sense that they have somewhere else to be. Or you might start feeling restless, and use an excuse to cut the conversation short. Sometimes, you feel like you could talk for HOURS. Chances are you’re wrong every time. In a study published this week in the Proceedings of the National Academy of Sciences, Adam Mastroianni and colleagues tried to figure out how good humans are at judging the ideal length of a conversation. They found that both participants agreed a conversation ended at the right time in only 2% of their trials. And the difference between one partner’s desired conversation length and the actual length of a conversation could be as much as 50%—so in a 10 minute conversation, your partner might have wanted to talk to you for as little as 5 minutes, or as much as 15 minutes. SciFri’s Charles Bergquist talks with Mastroianni about these results, and why the “exit ramps” to a conversation are rarely where you want them to be. Talking Through The History Of Our Teeth Most of us have never thought much about why we have teeth. But if you’re the parent of a teething infant, the question becomes a whole lot more relevant: While you impatiently wait for baby’s teeth to poke through, or soothe your teething toddler in the middle of the night, you might find yourself wondering why humans go through all this trouble for a set of teeth that are only temporary. In a decade, your child will have shed their baby teeth to make room for their adult counterparts, and all this fuss will be but a distant—albeit painful—memory for both you and your former infant. But one such question can lead to another. Are baby and adult teeth made of the same stuff? Why can’t we just grow a new tooth if we lose one? And how did ancient people take care of their teeth? Biological anthropologist and ancient tooth expert Shara Bailey joins Ira to discuss why our teeth are the way they are. A Look Back At The Time Of The Tasmanian Tiger Last week, conservation biologists on Twitter were all aflutter as rumors circulated that a creature called a “thylacine,” better known as a “Tasmanian tiger,” had been caught on camera in the Tasmanian bush. Thylacines have been considered extinct since the mid 80’s, but there are still those who believe—or hope—they still exist. In a video posted to YouTube, Neil Waters, President of the Thylacine Awareness Group of Australia, shared the news of what he thought looked like images of two adult thylacines and a baby. Unfortunately, this time the animal caught on camera was identified as a pademelon. But at Science Friday, we’ll never pass up an opportunity to celebrate a charismatic creature. Last January, SciFri’s Elah Feder spoke with Neil Waters and Gregory Berns, a psychology professor at Emory University, about the fascinating history of the Tasmanian tiger.
Vervet monkeys steal it out of people's hands. Chimpanzees in Guinea are known to climb up palm trees and drink it. There’s even a theory that loving it was an important adaptation for our pre-human ancestors, that the smell of fermentation helped them track down very ripe, calorie-rich fruit. Alcohol has been deeply ingrained in our lives from the beginning, possibly since before we were human. And while the drive to drink is older than civilization, many have worked hard to reign it in. In 1920s America, these desires clashed like never before. It’s a story of a battle between chemists, and the unthinkable lengths the U.S. government went to to try to pry away our favorite mind-altering substance.

In 1920, a Czech writer was stumped. He’d written a play about a future where machines that looked like people do our bidding. They were the perfect workers: obedient, hard working, and never demanded a pay raise. But what was the writer to call these marvelous machines? There wasn’t yet a word for this type of creation. He had initially chosen labori, from the Latin for labor, but something about the word wasn’t quite right. It seemed...stiff, bookish. This play wasn’t just about machines who labored. It was about machines we exploited, relentlessly. And eventually, the writer landed on a word that fit better: Robot. Robot comes from an old Czech word for drudgery and servitude. Though in his play - like so very many robo-dystopias to come - the writer showed that a mind we create to serve us, isn’t necessarily a mind we can control.

On December 5th, 2012, a bill landed on President Barack Obama’s desk, meant to do one thing: remove the word “lunatic” from the federal code. This is because in 2012, you could still find the word in laws about banking and controlling estates, among others. And not only was it offensive, it was antiquated—ancient, in fact. The word lunacy comes from luna—Latin for moon. This is because there was a time when we thought the power to change our moods and minds came from the sky.

In the late 18th century, a doctor showed up in Paris practicing some very peculiar medicine. He would escort patients into dimly lit rooms, wave his arms over their bodies, and touch them with a magnetic wand. Patients would react to these treatments violently: crying, sweating, convulsing or shrieking. But then they would emerge healed. According to the doctor anyway. Many believed he was a fraud, but despite his dubious methods, this doctor inadvertently gave us a new approach to healing—and a new word: mesmerize. Because the doctor’s name was Franz Anton Mesmer. A depiction of Mesmer’s “treatment” baquets. (Wikimedia Commons) Guests: Emily Ogden is an associate English professor at the University of Virginia.

Can You Get COVID-19 More Than Once? SciFri producer Elah Feder’s friend tested positive for antibodies a few months ago—but last month, she developed COVID-19 symptoms again. So far, only a handful of cases of COVID reinfection have been confirmed, but we don’t yet know the true rates. Cases could be missed if the first or second infection is asymptomatic, and sometimes, what looks like a case of reinfection is something else entirely. Over the past few months, we’ve seen both concerns that antibodies to SARS-CoV-2 fade quickly and reassurances that immunity probably endures. Akiko Iwasaki, an immunobiologist at Yale, along with Alessandro Sette and Shane Crotty of the La Jolla Institute for Immunology, explain what we know about the immune system’s ability to remember this virus, and what cases of reinfection could mean for the efficacy of vaccines. What Is The Future of Meat? More and more people are trying meat alternatives, and for good reason: The meat industry is a major contributor to climate change. Almost 15 percent of greenhouse gas emissions come from livestock, with cattle making up about two-thirds of that. Others avoid meat because of ethical problems with slaughtering animals. Altogether, plant-based meats are having a major moment, making their way onto the shelves of major grocery stores, and the menus of fast food chains. It’s now possible to eat a burger that tastes, looks, and feels like beef—while being entirely made of plants. Some scientists are devoting their careers to creating a future where more meat comes from plants, or even cells grown in a lab. Joining Ira to mull over the future of meat is Pat Brown, CEO of Impossible Foods, and Isha Datar, executive director of New Harvest, a non-profit that promotes the research and development of cell-based animal products.
How did we wind up with a storm named Iota? Well, we ran out of hurricane names. Every year, the World Meteorological Organization puts out a list of 21 names for the season’s hurricanes and tropical storms. But this year, the Atlantic hurricane season was so active that by September, we'd flown through the whole list of names and had to switch to the Greek alphabet. Thus, Hurricane Iota became the 30th named storm of the season. We’ve only had to dip into the Greek alphabet once before, in 2005. But the practice of naming hurricanes goes back to the 19th century, and it was a bit of a bumpy ride to land on the system we use today. In this episode: The story of a meteorologist in Australia, a novel, and a second-wave feminist from Florida—and how they brought us hurricane names. A transcript for this episode is being processed. We'll update the link when it's ready. Guests: Christina M.

The first Oreo rolled out of Chelsea Market in Manhattan in 1912, but despite the cookie’s popularity today, Oreos weren’t an immediate cookie smash hit. In fact, there was already another cookie on the block that looked remarkably similar to Oreos: two chocolate wafers embossed with laurel leaves, and white cream in the center. This cookie was widely loved, made with the highest quality ingredients, and saddled with a curious name: Hydrox. So how did a cookie get a name so bad? Producer Alexa Lim takes us all the way back to the early 1900s, and brings us a story of the rise - and the crumble - of a cookie named Hydrox. Guests: Carolyn Burns is the owner of The Insight Connection, and a former marketing director for Keebler. Stella Parks is a pastry chef and the author of Brave Tart: Iconic American Desserts.

In the 1760s, a new kind of establishment started popping up in Paris, catering to the French and fancy. These places had tables, menus, and servers. They even called themselves “restaurants,” and you might have too, were it not for one key difference: these restaurants were places you went not to eat. Well, not to chew anyway. Because they weren’t in the business of feeding their genteel clientele, but of soothing their frayed nerves —with premium medicinal soups. Soups which were also called “restaurants”! In this episode: How restaurants evolved from a soup to a chic Parisian soup spa to the diverse, loved—and sorely missed—solid food eateries of today.

Salty, sweet, sour, bitter. Scientists once thought these were the only tastes, but in the early 20th century, a Japanese chemist dissected his favorite kombu broth and discovered one more: umami. In recent years, umami has become a foodie buzzword, but for nearly a century, the Western world was in full-blown umami denial—didn’t believe it existed. And we might have stayed that way if it weren’t for our most notorious and potent source of umami: MSG. A 1930s advertisement for Ajinomoto. (Courtesy of the Science History Institute.) Advertising brochure from the late 1940s until the early 1950s for Ac'cent, an MSG product manufactured by the International Minerals & Chemical Corporation.

Rocky Road is just a good name for an ice cream flavor. So good, in fact, that two ice cream institutions have dueling claims to Rocky Road’s invention. It’s a story of alleged confessions and a whole lot of ice cream-fueled drama. If it were just the flavor that made Rocky Road so special, every company could have just made their own concoction of nuts, chocolate, and marshmallows, named it “Muddy Street” or “Pebble Lane,” and called it a day. But there’s a linguistic reason why Rocky Road just sounds so dang delicious—and it’s studied by linguists and marketers alike. Fenton's Creamery in Oakland, California, one of the institutions that lays claim to inventing Rocky Road. (Wikimedia Commons) In this episode, we mention the Bouba Kiki Effect. Imagine two shapes: One is a pointy, jagged polygon, the other an ameboid-like splotch. Which shape would you name “Bouba,” and which would you name “Kiki?” In study after study, 90% of people agree—the pointy shape is “Kiki” and the rounded shape is “Bouba.” This so-called “Bouba-Kiki Effect” holds in many languages, and has even been demonstrated with toddlers. But why the near-universal agreement? Cognitive psychologists like Kelly McCormick have several theories. Watch this Science Friday video to learn more.

At the turn of the 20th century, 12 young men sat in the basement of the Department of Agriculture, eating meals with a side of borax, salicylic acid, or formaldehyde. They were called the Poison Squad, and they were part of a government experiment to figure out whether popular food additives were safe. (Spoiler: Many weren’t.) Food manufacturers weren’t pleased with the findings, but one prominent ketchup maker paid attention. Influenced by these experiments, he transformed ketchup into the all-American condiment that we know and love today. Except ketchup—both the sauce and the word—didn't come from the United States.

In the fall of 1918, Philadelphia newspapers announced that a new virus had arrived in the city, the so-called “Spanish flu.” But the facts and scope were muddy and uncertain, and the city decided to push forward with a highly-anticipated parade. About 200,000 people showed up, and packed onto sidewalks. Halfway across the country, St. Louis, Missouri looked very different that fall. Businesses shuttered, movie theatres went dark, and students stayed home. Just like today, cities across the U.S. responded to the 1918 influenza pandemic differently—with very different results. In this episode, we go back to 1918 and a pandemic which wasn’t Spanish at all. Footnotes And Further Reading: Get into the nitty gritty of viral evolution with "1918 Influenza: the Mother of All Pandemics” which reviews the 1918 pandemic and all outbreaks it later spawned. The CDC’s Pandemic Influenza Storybook paints a vivid picture of life during the pandemic. We first learned about Philadelphia’s Liberty Loan Parade from the Washington Post’s reporting. For this story, we read many old articles from newspapers across the country, all archived on newspapers.com (available with a subscription).

Quarantine has been on many of our minds lately. The phrases “shelter in place” and “self-quarantine” have filled up our news, social media, and conversations since the first inklings of the coronavirus pandemic. But this is far from the first time cities and countries have used the practice of physical separation to battle the spread of disease. You might think of Mary Mallon, who many know as “Typhoid Mary.” In the early 1900s, she spent nearly 30 years in a cottage on a small island in New York City’s East River, all to prevent her from infecting others. But we’ve been using quarantine for millennia—well before we even understood germs existed and that they can be transmitted from person-to-person. And the origin of the word stretches all the way back to the mid-14th century, when Europe was swept by one of the biggest losses of human life in history: the Black Death.

Cobalt has been hoodwinking people since the day it was pried from the earth. Named after a pesky spirit from German folklore, trickery is embedded in its name. In 1940s Netherlands, cobalt lived up to its name in a big way, playing a starring role in one of the most embarrassing art swindles of the 19th century. It’s a story of duped Nazis, a shocking court testimony, and one fateful mistake. Want more Science Diction? Subscribe wherever you get your podcasts, and sign up for our newsletter.

At the turn of the 19th century, Britons would stroll along the Yorkshire Coast, stumbling across unfathomably big bones. These mysterious fossils were all but tumbling out of the cliffside, but people had no idea what to call them. There wasn’t a name for this new class of creatures. Until Richard Owen came along. Owen was an exceptionally talented naturalist, with over 600 scientific books and papers. But perhaps his most lasting claim to fame is that he gave these fossils a name: the dinosaurs. And then he went ahead and sabotaged his own good name by picking a fight with one of the world’s most revered scientists. Want more Science Diction?

For centuries, smallpox seemed unbeatable. People had tried nearly everything to knock it out—from herbal remedies to tossing back 12 bottles of beer a day (yep, that was a real recommendation from a 17th century doctor), to intentionally infecting themselves with smallpox and hoping they didn’t get sick, all to no avail. And then, in the 18th century, an English doctor heard a rumor about a possible solution. It wasn’t a cure, but if it worked, it would stop smallpox before it started. So one spring day, with the help of a milkmaid, an eight-year-old boy, and a cow named Blossom, the English doctor decided to run an experiment. Thanks to that ethically questionable but ultimately world-altering experiment (and Blossom the cow) we got the word vaccine. Want more Science Diction?

Remember that summer when the internet was one Distracted Boyfriend after another—that flannel-shirted dude rubbernecking at a passing woman, while his girlfriend glares at him? Everyone had their own take—the Boyfriend was you, staring directly at a solar eclipse, ignoring science. The Boyfriend was youth, seduced by socialism, spurning capitalism. The Boyfriend could be anyone you wanted him to be. We think of memes as a uniquely internet phenomenon. But the word meme originally had nothing to do with the internet.

These days, biologists believe all living things come from other living things. But for a long time, people believed that life would, from time to time, spontaneously pop into existence more often—and not just that one time at the base of the evolutionary tree. Even the likes of Aristotle believed in the “spontaneous generation” of life, until Louis Pasteur debunked the theory—or so the story goes. In a famous set of experiments, Pasteur showed that when you take a broth, boil it to kill all the microscopic organisms floating inside, and don't let any dust get in, it stays dead. No life will spontaneously emerge. His experiments have been considered a win for science—but according to historian James Strick, they might have actually been a win for religion. This episode originally aired on Science Friday, when Elah joined Ira Flatow and science historian, James Strick, to find out what scientists of Pasteur's day really thought of his experiment, the role the Catholic church played in shutting down “spontaneous generation,” and why even Darwin did his best to dodge the topic. FOOTNOTES Though Darwin was bold enough to go public with his theory of evolution, he seemed to shy away from the spontaneous generation debate. But his theory inevitably invited the question: if life could spontaneously arise once on Earth, why not many times? James Strick writes about Darwin's complicated relationship with spontaneous generation. The basic premise of Louis Pasteur's famous swan-necked flask experiment is shown below. The swan necks let life-nourishing air into the flask, but kept potentially contaminating dust out. Louis Pasteur's spontaneous generation experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the air itself. These experiments were important piece (Credit: Public Domain via Wikimedia Commons) GUEST James Strick, associate professor at Franklin and Marshall College CREDITS This episode of Undiscovered was produced by Elah Feder and Alexa Lim.

In August 2018, NASA sent the Parker Solar Probe off on its anticipated seven-year-long mission to study the sun. Already, it has completed three of its 24 scheduled orbits, and data from two of those orbits are already telling us things we didn't know about the star at the center of our solar system. The probe has collected information on the factors that influence the speed of solar wind, the amount of dust in the sun's bubble-like region—the heliosphere—and also where scientists' models were wrong. David McComas, professor of astrophysical sciences at Princeton University and principal investigator of the integrated science investigation of the sun, breaks down the very first data collected from the Parker Solar Probe mission. He's joined by Aleida Higginson, Parker Solar Probe deputy project scientist for science operations, who will update us on the mission that's giving us an unprecedented look at our sun. What makes a creature charismatic? In our new segment, we'll feature one creature a month, and try to convince you that it's worthy of the coveted Charismatic Creature title. By “creature” we mean almost anything—animals, viruses, subterranean fungal networks, you name it. And by “charismatic,” we don't just mean cute, clever, or even all that nice! We just mean they have that special something that makes us want to lean in and learn everything about them—because they can't all be baby pandas. Over the past two months, we've received dozens of listener suggestions—everything from turtles to tardigrades. We had to choose just one, and we're starting simple—single celled simple. Our first charismatic creature is Physarum polycephalum, the “multi-headed” slime mold. Despite having no brain or neurons and being just one giant goopy cell, these slime molds keep defying our expectations. They can solve mazes, recreate the Tokyo railway network (animation below), learn, and even anticipate events. They can make rational and irrational choices that mirror our own. Not to mention they're visually stunning too. Despite having no brain or neurons and being just one giant goopy cell, these slime molds keep defying our expectations.

Oregon is not very good at recycling, and it's getting worse, according to a new report. Overall recycling rates in the state have steadily declined for the last several years, even as the amount of waste generated per person in the state has grown. The report, published Thursday by the group Environment Oregon, uses data released yearly by the Oregon Department of Environmental Quality. It finds that Oregon faces major barriers to meeting its recycling goals. Nationally, recyclable plastics are being replaced with lower-value plastics. In Oregon, polystyrene (the flaky, foam-like material used in single-use coffee cups) isn't recycled by municipal governments, and a legislative proposal to ban it statewide failed last year. Consumers can take certain polystyrene products to privately run drop boxes in some cities around the state. This doesn't mean that Oregonians aren't passionate about recycling. The biggest barrier to recycling in Oregon is structural: less of the material placed in recycling bins can be repurposed by domestic facilities, and exporting recyclables to countries like China has become more difficult. “The bottom line is, we need to take more of these products out of the waste stream,” Celeste Meiffren-Swango, the state director of Environment Oregon, said. It's not just an Oregon problem, it's a national—even global—issue. For years, recycling in the United States has relied on Asian countries to take our waste. Many countries, finding that arrangement unprofitable, have started incinerating the recycling, dumping it in landfills, or simply stopped accepting recyclables from the United States altogether. The few countries that still purchase U.S. recyclables are increasingly facing unexpected health impacts stemming from too much waste and no way to process it. Subscribe to this podcast.

“Do men need to cheat on their women?” a Playboy headline asked in the summer of 1978. Their not-so-surprising conclusion: Yes! Science says so! The idea that men are promiscuous by nature, while women are chaste and monogamous, is an old and tenacious one. As far back as Darwin, scientists were churning out theory and evidence that backed this up. In this episode, Annie and Elah go back to the 1970s and 1980s, when feminism and science come face to face, and it becomes clear that a lot of animals—humans and bluebirds included—are not playing by the rules. GUESTS Angela Saini, author of Inferior: How Science Got Women Wrong Patricia Adair Gowaty, professor emeritus at UCLA, editor of Feminism and Evolutionary Biology. FOOTNOTES Sarah B. Hrdy is an anthropologist, feminist, and a major figure in this chapter of science history. In this book chapter she addresses the myth of the “coy female” and reviews the relevant scientific happenings of the 1970s and 80s, especially in the primatology sphere. Angus John Bateman's 1948 paper about fruit fly mating and reproductive success, popularized by this paper from Robert Trivers in 1972. Bateman finds that males have more reproductive success the more females they mate with, and that females don't benefit as much from mating with multiple males. Patty Adair Gowaty found holes in Bateman's study. Bateman didn't know exactly how many sexual partners his fruit flies had because he didn't watch them. Instead, he counted up how many offspring they made. Unfortunately, a lot of them had harmful mutations and died—skewing his numbers. Not only do they not meet Mendelian expectations, but in Bateman's data, he consistently counts more fathers than mothers—which can't be right, since every baby fly has one mother and one father. Patty found that eastern bluebird females successfully raise offspring without help from their male partners. Patty and Alvan Karlin found that eastern bluebird babies aren't always related to the parents raising them. True “genetic monogamy,” where bird couples only have sex with each other, appears to be the exception, not the rule in passerines. Polyandry—where females have sex with multiple males—has been found most of the species studied! In the late ‘70s and early ‘80s, a psychology study at Florida State University found that most men, and no women would accept a sex invitation from a stranger. In this more recent Germany study, 97% of the women expressed interest in sex with at least one strange man, but only when researchers promised to arrange a (relatively) safe encounter. Btw, Patty tells us bluebirds don't actually have sex in the nest, so having sex “outside the nest” is the norm. We were using the expression figuratively, but worth noting. The nest is really for storing the babies. CREDITS This episode was reported and produced by Elah Feder and Annie Minoff. Our senior editor is Christopher Intagliata. Fact checking by Robin Palmer.

Much has been written about the Manhattan Project, the American-led project to develop the atomic bomb. Less well known is Nazi Germany's “Uranium Club”—a similar project started a full two years before the Manhattan Project. The Nazis had some of the greatest chemists and physicists in the world on their side, including Werner Heisenberg, and the Allies were terrified that the Nazis would beat them to the bomb—meaning the Allies were willing to try anything from espionage to assassination to bombing raids to stop them. Science writer Sam Kean joins Ira to tell the high-stakes story written in his new book The Bastard Brigade: The True Story of the Renegade Scientists and Spies Who Sabotaged the Nazi Atomic Bomb. Plus, "spontaneous generation" was the idea that living organisms can spring into existence from non-living matter. In the late 19th century, in a showdown between chemist Louis Pasteur and biologist Felix Pouchet put on by the French Academy of Sciences, Pasteur famously came up with an experiment that debunked the theory. He showed that when you boil an infusion to kill everything inside and don't let any particles get into it, life will not spontaneously emerge inside. His experiments have been considered a win for science—but they weren't without controversy. In this interview, Undiscovered's Elah Feder, Ira Flatow, and historian James Strick talk about what scientists of Pasteur's day really thought of his experiment, the role the Catholic church played in shutting down “spontaneous generation,” and why even Darwin did his best to dodge the topic.

Blood is essential to human life—it runs through all of our bodies, keeping us alive—but the life-giving liquid can also have a mysterious, almost magical quality. As journalist Rose George points out, this association goes back to thousands of years, even showing up in “The Odyssey.“ Odysseus, while traveling in Hades, comes across his mother Anticlea, who will not speak to him. At least, she says, “Not until she drinks the blood that Odysseus has taken from reluctant sheep. For Homer, blood had a power as fierce and invisible as electricity: a mouthful of blood, a switch flicked, and Anticlea could now speak to her son.” George's new book, “Nine Pints: A Journey Through the Money, Medicine, and Mysteries of Blood,” traces the cultural significance and business of blood. She talks about how we've tried to harness blood through the idea of the blood banking happened in 1937 at Chicago's Cook County Hospital and the search for possible synthetic substitutes. Take a deep breath in. With one single inhalation, the human nose takes in a bunch of information about your environment. And unlike vision and hearing, that information goes straight to the limbic system, the part of the brain that controls emotion and memory. Recent studies suggest that rhythmic breathing through the nose (as opposed to mouth breathing) can have a have a positive impact on these brain regions. On November 6th, millions of Americans will cast their votes in districts that have been declared unconstitutional by a federal court. A panel of three judges ruled that North Carolina's congressional districts had been unfairly gerrymandered to favor Republicans over Democrats—and the key evidence in the case? Math. Annie Minoff and Elah Feder tell the story of that case—now waiting to be considered by the Supreme Court—in the next episode of Undiscovered. Subscribe to this podcast.

As a critical care doctor, Jessica Zitter has seen plenty of “Hail Mary” attempts to save dying patients go bad—attempts where doctors try interventions that don't change the outcome, but do lead to more patient suffering. It's left her distrustful of flashy medical technology and a culture that insists that more treatment is always better. But when a new patient goes into cardiac arrest, the case doesn't play out the way Jessica expected. She finds herself fighting for hours to revive him—and reaching for a game-changing technology that uncomfortably blurs the lines between life and death.

Since the 1980s, Gerta Keller, professor of paleontology and geology at Princeton, has been speaking out against an idea most of us take as scientific gospel: That a giant rock from space killed the dinosaurs. Nice story, she says—but it's just not true. Gerta's been shouted down and ostracized at conferences, but in three decades, she hasn't backed down. And now, things might finally be coming around for Gerta's theory. But is she right? Did something else kill the dinosaurs? Or is she just too proud to admit she's been wrong for 30 years? Subscribe to Undiscovered HERE, or wherever you get your podcasts. GUESTS Gerta Keller, professor of paleontology and geology at Princeton James Powell, geologist and author of Night Comes to the Cretaceous: Dinosaur Extinction and the Transformation of Modern Geology (St. Martin's Press) FOOTNOTES Michael Benton reviews the many, sometimes hilarious explanations for the (non-avian) dinosaurs' extinction.

Last month, California passed a bill ending the use of cash bail. Instead of waiting in jail or putting down a cash deposit to await trial at home, defendants are released after the pleadings. The catch? Not everyone gets this treatment. It's not a judge who determines who should and shouldn't be released; it's an algorithm. Algorithms have also been used to figure out which incarcerated individuals should be released on parole. Mathematician Hannah Fry and computer scientist Suresh Venkatasubramanian join Ira to discuss how algorithms are being used not only in the justice system, but in healthcare and data mining too. As Hurricane Florence approaches the Carolinas this week, forecasters and disaster management officials are stressing one key piece of advice to evacuating residents: Take the storm seriously, regardless of the category designation. Once projected to hit Category 4, Florence was at Category 2 as of Thursday morning, but that number only describes the wind speed. Meanwhile, as University of California-Irvine civil engineer Amir AghaKouchak notes, there could be unusually devastating flooding, as storm surge from the ocean meets rainfall from a storm that is projected to pour on the region for days. “Compound flooding” is the phenomenon that left Houston under water after Hurricane Harvey in 2017, and, at its worse, could cause rivers to run in reverse. And, AghaKouchak says, climate change and sea level rise both make such flooding more likely in storms like Florence. The prevailing theory says a meteorite led to the demise of the dinos. But Gerta Keller, a longtime geologist and paleontologist, isn't buying it, and says volcanoes were the real culprit. The latest episode of Undiscovered tells her story, and asks whether conflict among scientists really makes science stronger. Co-hosts Elah Feder and Annie Minoff join Ira for a preview.

A decade ago, psychologists introduced a group of kids to Robovie, a wide-eyed robot who could talk, play, and hug like a pro. And then, the researchers did something heartbreaking to Robovie! They wanted to see just how far kids' empathy for a robot would go. What the researchers didn't gamble on was just how complicated their own feelings for Robovie would get. Annie and Elah explore the robot-human bond.
