Where Are The Black Physicists? Black scientists make up less than one percent of physics PhDs in the U.S. And since 1999, most physics departments in the country have failed to graduate more than one or two Black undergraduates. Furthermore, the share of Black students in physics is declining: If the number receiving a bachelor's degree in physics had kept pace with the rising popularity of the major, there would be 350 Black physicists graduating every year. Instead, in 2020, that number was 262. But why is this number so small? A comprehensive investigative series in Science Magazine this week examines those statistics, the academic climate of physics departments, and how academia may be limiting the achievement of Black students. The series also highlights some success stories about proposed solutions, with mixed results. But why is physics a uniquely white, male discipline—and how can institutions make the climate more friendly to students from marginalized backgrounds? Ira talks to Apriel Hodari, one of 150 Black women to receive a PhD in physics in the U.S., who now researches the culture of higher education in STEM fields.   Why The Equinox Can Make Your Credit Card Fail Twice a year, people listening to signals from satellites in geostationary orbit face a problem known as a solar outage, a solar transit, or sun fade. Around the spring equinox, the Sun approaches the equator from the south, as the north gets ready for spring. In the fall, near the autumnal equinox, the Sun appears to move back below the equator. During these times, it comes into the view of Earthbound satellite dishes directed at geostationary satellites positioned some 22,000 miles above the equator. When a ground receiver, the satellite it's looking at, and the Sun all line up, the radiation from the Sun can temporarily overwhelm the satellite receiver. Think of it like when you're driving on a westbound road close to sunset, and you're staring straight into the setting sun—it gets hard to read the road signs. The effect is temporary: a maximum of 12 minutes at any given location for several days in a row. But it can affect everything from a satellite TV dish to credit card processing at your local gas station—even public radio stations receiving live programming over the satellite network. SciFri's Charles Bergquist talks with Chris DeBoy, who teaches a course in satellite communications at the Johns Hopkins University (and is also the RF communications lead for the New Horizons Mission to Pluto, and the Space Engineering Branch Manager at the Johns Hopkins Applied Physics Laboratory), about the advantages and disadvantages of geostationary satellites, and what can be done to minimize the impact of solar outages. They are joined by MaryJane Peters, technical operations chief at KAZU in Monterey, California, who describes the effect the seasonal outages have on station operations. Can Meteorites On Earth Point To Ancient Life On Mars? In 1996, the late astrobiologist David McKay and his team published a paper arguing that a four-pound rock from Mars, called Allan Hills 84001 (found in Antarctica), showed evidence of ancient microbial life on the planet Mars. The team pointed to several mineral structures, including tiny beads of magnetite, as well as shapes that might be fossilized bacteria. This hypothesis ignited a storm of controversy and a flurry of research that contradicted the team's theory. But decades later, ALH 84001, like the other meteorites that have been linked to the Red Planet, remains an important insight into Martian geology and the formation of organic molecules in the absence of biological processes. Producer Christie Taylor talks to astrobiologist Andrew Steele, who has been studying ALH 84001 and other meteorites for decades. He discusses the process of probing meteorites for data, the difficulty of studying rocks without their original contexts, and how new samples from the Perseverance rover could change everything. Plus, how the original controversy over ALH 84001 changed the trajectory of planetary science.   From Zero To 100 Butts: The Wild World Of Invertebrate Behinds Recently, the staff of Science Friday came across a tweet that caught our attention, sent out by researcher Dr. Maureen Berg.   Turns out, it was a call to source comic ideas for Invertebrate Butt Week, a celebration of—you guessed it—the butts of invertebrates. “Invertebrates really get the short end of the stick,” says Rosemary Mosco, the creator of the comic series Bird And Moon and #InverteButtWeek organizer. “People are not as excited about them as, say, a majestic whale or a beautiful bird. And I love my birds, but [invertebrates have] such an incredible diversity. So, butts are sort of a cheeky way to access some of that amazing diversity and celebrate it.”   Rosemary and other scientists and illustrators teamed up to create #InverteButtWeek, a celebration of the behinds of the backbone-less. “It's a chance for some people who do science communication to do the silliest thing that they can possibly think of,” says Dr. Ainsley Seago, curator of invertebrate zoology at the Carnegie Museum of Natural History.   Science Friday's Daniel Peterschmidt talks to the organizers of #InverteButtWeek about how it came together, their favorite invertebrate butt facts (like how sea cucumbers have anal teeth), and how you can participate in the celebration.

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.  Bart Chezar is a chestnut enthusiast, and volunteers with the Prospect Park Alliance.

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.

Head on over to plainlanguage.gov, and you'll find a helpful table, dedicated to simplifying and demystifying military jargon. On one side of the table, there's the jargon term, and on the other, its plain language equivalent. “Arbitrarily deprive of life”? Actually just means “kill people.” “Render nonviable”? Also means “kill people.” “Terminate with extreme prejudice”? “Kill people.”    This table is just one of many resources on plainlanguage.gov—from checklists to plain language training to thesauruses. The website was created by an unfunded government group of plain language activists who make it their mission to translate government communications into regular old, plain language.  But jargon isn't just a government problem. It pops up in nearly every field, and it seems like it annoys most of us. So why do we use it? And is there anything actually good about it?   This episode was inspired by a question from a listener, Jafar, who asked about the word “recrudescence” and why we tend to use fancy words when simple ones would work just fine.

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.

When Isabel Briggs Myers imagined that her homegrown personality test would change the world, she couldn't have pictured this. Today, millions take the Myers-Briggs Type Indicator each year. Countless organizations use it, from General Motors to the CIA. But there's one field that mostly rolls its eyes at the test: psychology.  In our final chapter, Isabel rescues her indicator from the verge of extinction, but has to make some compromises. And we explore what the Myers Briggs does (and doesn't) measure, and why people love it despite psychologists' complaints. Listen to Chapter 1 and Chapter 2 of this series.

At first, it seemed like Isabel Briggs Myers would have nothing to do with personality typology. That was her mother Katharine's passion project, not hers. But when Isabel enters a tumultuous marriage, she discovers that her mother's gospel of type might just be the thing to save it.  In Chapter 2, Isabel picks up her mother's work, and decides to transform it into a marketable product—but first, she has to convince a group of skeptical PhDs that it actually works. Along the way, one particularly dogged researcher notices some issues with her indicator, threatening to undo everything she'd worked for. If you're new to the series, listen to Chapter 1.

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.  Guest:  Merve Emre is a writer and English professor at the University of Oxford.

Honeymoon: It just seems like a word that would have a lovely story behind it, doesn't it?  When a listener named Eric emailed us from Centerville, Ohio asking about the word, that's what we were hoping to find. Instead, we found a more bittersweet origin stretching all the way back to an early modern poem.

A transcript for this episode is in progress. In 1910, a fruit fly geneticist named Thomas Hunt Morgan noticed something strange in one of his specimens. Out of his many, many fruit flies—all with brilliant red eyes—a single fly had white eyes. This fruit fly turned out to be a very big deal. From those white eyes, Morgan eventually figured out that genes can be sex-linked, confirmed that genes exist on chromosomes, and won the Nobel prize. But he also cemented his legacy another way, with what he chose to name that gene: “white.” It might sound uninspired, but it kicked off a tradition that decades later gave us names like spatzle, hamlet, and ken and barbie. Here and there, a name went too far, but overall, fanciful names brought joy to researchers and worked well—until genes like these were discovered in humans, and everything went awry. Johanna and Senior Producer Elah Feder team up with Helen Zaltzman of The Allusionist to talk about fruit flies, genes, and whether it's ok to name a gene after a German noodle. Plus, after much demand, we bring you... the origin of defenestration! Guests:  Helen Zaltzman is the host of The Allusionist.

If you read the title of this episode and cringed, you're not alone. At Merriam-Webster, editors and lexicographers receive countless letters grousing about the addition of certain words to the dictionary. And here at Science Diction, we get our fair share of emails pointing out our linguistic missteps.  But the more you dig into the origins of words, the more you notice that when it comes to language, “correctness” is a slippery concept. In fact, some of our most beloved English words - nickname! newt! - were born of mistakes.  In this episode, Merriam-Webster lexicographers Emily Brewster and Peter Sokolowski explain the mistake-ridden origins of our words, how language evolves, and how wrong becomes right. Plus, we answer a listener question about the most exported word in the English language.

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.

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.

One year into this pandemic, it’s been a struggle to feel a connection with other people digitally. That’s why I was inspired to hear an episode from the show Science Friday about a community that refused to disband their virtual world. As reporter Daniel Peterschmidt explains to me, the staff of Science Friday had set up a virtual outpost in Second Life when it was a trendy thing to do in the mid-2000s. The show eventually left Second Life, but Daniel recently discovered their community of hardcore fans stuck together long after many people abandoned Second Life, and the group went through not-so virtual turmoil along the way.  Today's episode is brought to you by SerialBox and BetterHelp.

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. Guests: Dan McAdams is a professor of psychology at Northwestern University.  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.

Learning From World Of Warcraft’s Virtual Pandemic The widespread infection of roughly four million virtual characters all started with a giant snake demon. In 2005, the massively multiplayer online video game World Of Warcraft introduced a special event raid, where groups of players could team up to fight a giant snake demon named Hakkar the Soulflayer. Hakkar would cast a spell called “Corrupted Blood” on players, which would slowly whittle down their health. The effect of the spell was only supposed to last inside the raid arena—when players returned to the main world of the game, the spell would dissipate. But thanks to a software glitch, that wasn’t the case if the player had a pet companion. When the pets returned to the main world, they started infecting players and non-playable characters with the Corrupted Blood spell. If the player wasn’t powerful enough to heal themselves, they would die and erupt in a fountain of blood before turning into a skeleton. What followed was a virtual pandemic that startlingly resembled today’s COVID-19 pandemic, from the spread, human behavior, and cultural response. Blizzard, the developer of the game, wanted players to social distance. Some players listened, others flouted the rules, traveling freely and spreading the disease with them. Conspiracy theories formed about how the virus was engineered by Blizzard on purpose, and others placed blame on players with pets as the cause of the outbreak, mirroring the racist anti-Asian attacks and rhetoric surrounding COVID-19 today.  Coincidentally, two epidemiologists, Nina Fefferman and Eric Lofgren, were there to witness the World Of Warcraft outbreak unfold. They studied and used the incident to model human behavior in response to a pandemic. Their findings were published in The Lancet in 2007. Many of their observations came to pass in 2020 when COVID-19 appeared.  SciFri producer Daniel Peterschmidt sat down with Eric Molinsky, host of the podcast Imaginary Worlds, who reported this story for his show. He talks about the epidemiologists who studied the outbreak and how it prepared them for public responses to COVID-19. Why Is Daydreaming Difficult For Grownups? Children have a natural talent for imagination. Even in moments of boredom, their imagination can take them away into daydreams that help pass the time in a flash. But for many adults, falling into a daydream is hard, especially when our minds are filled with worries about tomorrow’s obligations, finances, and a global pandemic.  Turns out those who feel this way are not alone. New research shows that adults report getting to a daydreaming state is harder than experiencing their unguided thoughts. Adults often require a prompt to think about something pleasant, and tend to ruminate on unpleasant things.  Daydreaming can be an antidote to boredom, and researcher Erin Westgate of the University of Florida says that’s important. Her previous research shows that boredom can cause sadistic behavior in people. Westgate joins guest host John Dankosky and Manoush Zomorodi, host of the TED Radio Hour and author of the book “Bored and Brilliant,” who argues leaning into boredom can unlock our most creative selves. Can We Geoengineer Our Way Out Of A Natural Disaster? Humans have always altered their landscapes—from simple agriculture used to cultivate specific crops to huge projects like damming rivers to change the flow of entire ecosystems. And many of these human interventions have unintended consequences and have led to major environmental disasters. In her book Under A White Sky: The Nature Of The Future, author Elizabeth Kolbert talks to scientists and people working on geoengineering projects and technology to mitigate and avert damage caused by humans in the natural world like climate change. The projects range from electrifying rivers to turning CO2 emissions into rocks. Kolbert discusses if we can solve these natural problems with the tools that created the problems in the first place, and at what cost?

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.

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.

The pearl clutching about “cancel culture” and “censorship” has become louder and more absurd while also getting more and more play in the media. Journalists Katelyn Burns and Oliver-Ash Kleine see this panic for what it is though: a grift. In this new podcast, they take a closer look at these temper tantrums, dispelling myths, laughing at the most outrageous takes, and shedding light on which perspectives are actually being suppressed and left out of the conversation.

They Might Be Giants With A Timely Reminder: “Science Is Real” Fans of the band They Might Be Giants are likely to be familiar with the band’s version of the 1959 Tom Glazer song “Why Does The Sun Shine?” As they sing, “The sun is a mass / of incandescent gas / a gigantic nuclear furnace.” In their album “Here Comes Science,” the band revisits that song, and follows it with a fact-checking track titled “Why Does the Sun Really Shine?” In the lyrics, they describe the science of plasma. The album also includes an ode to the elements, descriptions of what blood does in the body, and songs describing the scientific process. In a reminder that resonates for the start of 2021, one song is titled “Science is Real.”   In this archival segment from 2009, John Linnell and John Flansburgh of They Might Be Giants join Ira in the studio to discuss the album, and to play some science songs.

The Luxury Ostrich Eggs Of The Bronze And Iron Age Upper Class Today, if you want to show off that you’ve made it, you might buy a top-of-the-line Rolex watch, or line your garage with Ferraris and Rolls Royces. But in the Iron and Bronze age, one of the luxury goods of choice was to put a highly decorated ostrich egg in your tomb. These status symbols have been found in multiple European Iron and Bronze Age locations, despite ostriches not being indigenous to the area. A team of scientists wanted to know the origins of these eggs—and just how they made it from Africa into the hands of the Iron and Bronze Age elite. Mediterranean archaeologist Tamar Hodos, an author on the study recently published in Antiquity, explains how the team determined that these eggs came from wild ostriches, rather than captive birds, and what this reveals about the ancient luxury trade. See a gallery of these ostrich eggs below!

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.

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.

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.

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.

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.

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.

Routine Healthcare Is Falling Through The COVID-19 Cracks Our healthcare system is straining under the weight of the coronavirus epidemic, with hospital emergency rooms and ICUs around the country facing shortages of masks, ventilators, hospital beds, and medical staff. But the epidemic is also upsetting parts of the healthcare system that aren’t directly treating COVID patients. How are you supposed to keep up with regular medical care when you’re not supposed to leave the house, or when your primary care doctor’s office is shut down Michael Barnett is an assistant professor at the Harvard T. H. Chan School of Public Health who studies access to healthcare services, as well as a primary care physician at Brigham and Women’s Hospital in Boston. He joins Ira to talk about how patients and clinics are attempting to navigate a healthcare landscape altered by the global pandemic—including telemedicine and virtual health services, the economics of private doctors’ offices, and shortages of regular medications. These Flowers Bounce Back Everywhere, colorful, spirit-lifting flowers are blooming. But if you’ve stepped off a path to avoid an oncoming runner recently, don’t worry. New research, published in the journal New Phytologist, finds some flowers have a unique ability to “bounce back” after injury—say after getting squished by a falling branch or shoe. This gives flowers a second chance at being pollinated, preserving their role in the seasonal ecosystem. One of the authors of this study, Nathan Muchhala, an assistant professor of biology at the University of Missouri in St. Louis, joins Science Friday to discuss the unique properties of flowers. How Dogs Are Helping Scientists Build A Smell Detector For Cancer Scientists are now training dogs to sniff out cancer. A team at UPenn and Monell Chemical Chemical Senses Center are using dogs’ heightened sense of smell to detect the specific chemicals produced by cancer cells. The scientists are using this data to produce a device that could be used in ovarian cancer detection.  Science Friday’s video producer Luke Groskin and digital producer Daniel Peterschmidt talk with Ira about a trip to the cancer laboratory, where they met the scientists—and dogs—behind this unique research. This is part of Science Friday’s Methods, where we bring you into the field alongside the scientists working to answer big questions, by using gorgeous video and pictures.

This helps determine who is following stay-at-home orders, and who isn’t. Facebook and Google want to use their data about user movements to do the same. But some say this is a big breach of privacy. Amy Nordrum of IEEE Spectrum joins Ira to discuss this story and more of the latest COVID-19 news. 

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?

“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.

Celebrating Apollo's 'Giant Leap' July 20, 1969 was a day that changed us forever—the first time humans left footprints on another world. In this segment, Ira Flatow and space historian Andy Chaikin celebrate that history and examine the legacy of the Apollo program. Apollo ushered in a new age of scientific discovery, with lunar samples that unlocked the history of how the moon and the solar system formed. It accelerated the development of new technologies, like the integrated circuit. And most of all, says Chaikin, it taught us how to work together, to achieve seemingly impossible goals.  We also take a look at what comes next for NASA's historic launchpads. Science Friday producers Alexa Lim and Daniel Peterschmidt went to NASA Kennedy Space Center at Cape Canaveral, Florida a few months ago. They got to see how the space agency is upgrading some of its storied launchpads—and leaving others behind to rising sea levels. Take Flight With Science Friday's Book Club Called anyone a “bird brain” recently? There was a time when we thought this meant “stupid,” deceived by the small size and smooth surface of birds' brains into thinking they were mere mindless bundles of feathers. But researchers are finding out what birds themselves have always known: Our feathered friends come with mental skills that might stump even humans. Be it tool-making, social smarts, navigation across vast distances, or even the infinitely adaptable house sparrow, Jennifer Ackerman writes of dozens of examples in this summer's SciFri Book Club pick, The Genius of Birds. Take homing pigeons, which can be released hundreds of miles from the roof and still eventually wing their way home. Or mockingbirds, who can memorize and mimic, with astonishing accuracy, the songs and calls of as many as 200 different other birds. And birds have other kinds of genius: Bowerbirds craft intricate displays to lure their mates, each species with its own particular aesthetic preferences, like the satin bowerbird's penchant for blue. Ira, Book Club captain Christie Taylor, and bird brain researchers Aaron Blaisdell and Lauren Riters convene for the summer Book Club kickoff, and a celebration of avian minds everywhere.

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.  Subscribe to Undiscovered HERE, or wherever you get your podcasts.   Resources Talking about end-of-life stuff can be hard!

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?

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. Subscribe to Undiscovered HERE, or wherever you get your podcasts   VIDEOS I Spy, And The Closet A fifteen-year-old study participant plays a game of I Spy with Robovie—and then watches as the robot is ordered into the closet.
