An 11-Year-old Unearthed Fossils Of The Largest Known Marine Reptile

When the dinosaurs walked the Earth, massive marine reptiles swam. Among them, a species of Ichthyosaur that measured over 80 feet long. Today, we look into how a chance discovery by a father-daughter duo of fossil hunters furthered paleontologist's understanding of the "giant fish lizard of the Severn." Currently, it is the largest marine reptile known to scientists.Read more about this specimen in the study published in the journal PLOS One.

The Nightmarish Worm That Lived 25 Million Years Longer Than Researchers Thought

500 million years ago, the world was a very different place. During this period of time, known as the Cambrian period, basically all life was in the water. The ocean was brimming with animals that looked pretty different from the ones we recognize today — including a group of predatory worms with a throat covered in teeth and spines. Researchers thought these tiny terrors died out at the end of the Cambrian period. But a paper published recently in the journal Biology Letters showed examples of a new species of this worm in the fossil record 25 million years after scientists thought they'd vanished from the Earth. One of the authors of the paper, Karma Nanglu, tells us how this finding may change how scientists understand the boundaries of time. Curious about other weird wonders of the ancient Earth?

How The Brain Experiences Pleasure — Even The Kind That Makes Us Feel Guilty

We've all been there: You sit down for one episode of a reality TV show, and six hours later you're sitting guiltily on the couch, blinking the screen-induced crust off your eyeballs. Okay. Maybe you haven't been there like our team has. But it's likely you have at least one guilty pleasure, whether it's playing video games, reading romance novels or getting swept into obscure corners of TikTok. It turns out that experiencing – and studying – pleasure is not as straightforward as it might seem. And yet, pleasure is quite literally key to the survival of humanity. So today on the show, we explore the pleasure cycle: What it is, where it lives in the brain and how to have a healthier relationship with the things that make us feel good. Want more on the brain? Email us the neuroscience you want us to talk about at [email protected]! (Also please email us if you would like to gush about any of the books you've been loving — romantasy or otherwise!)Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

What To Know About The New EPA Rule Limiting 'Forever Chemicals' In Tap Water

Wednesday the Environmental Protection Agency announced new drinking water standards to limit people's exposure to some PFAS chemicals. For decades, PFAS have been used to waterproof and stain-proof a variety of consumer products. These "forever chemicals" in a host of products — everything from raincoats and the Teflon of nonstick pans to makeup to furniture and firefighting foam. Because PFAS take a very long time to break down, they can accumulate in humans and the environment. Now, a growing body of research is linking them to human health problems like serious illness, some cancers, lower fertility and liver damage. Science correspondent Pien Huang joins the show today to talk through this new EPA rule — what the threshold for safe levels of PFAS in tap water is, why the rule is happening now and how the federal standards will be implemented.Read more of Pien's reporting on the EPA's first ever rule on PFAS in drinking water.Want to hear more about health and human safety?

The Order Your Siblings Were Born In May Play A Role In Identity And Sexuality

It's National Siblings Day! To mark the occasion, guest host Selena Simmons-Duffin is exploring a detail very personal to her: How the number of older brothers a person has can influence their sexuality. Scientific research on sexuality has a dark history, with long-lasting harmful effects on queer communities. Much of the early research has also been debunked over time. But not this "fraternal birth order effect." The fact that a person's likelihood of being gay increases with each older brother has been found all over the world – from Turkey to North America, Brazil, the Netherlands and beyond. Today, Selena gets into all the details: What this effect is, how it's been studied and what it can (and can't) explain about sexuality.Interested in reading more about the science surrounding some of our closest relatives?

The "Barcodes" Powering These Tiny Songbirds' Memories May Also Help Human Memory

Tiny, black-capped chickadees have big memories. They stash food in hundreds to thousands of locations in the wild – and then come back to these stashes when other food sources are low. Now, researchers at Columbia University's Zuckerman Institute think neural activity that works like a barcode may be to thank for this impressive feat — and that it might be a clue for how memories work across species.

The Shy Rodents Lost To Science

Historic numbers of animals across the globe have become endangered or pushed to extinction. But some of these species sit in limbo — not definitively extinct yet missing from the scientific record. Rediscovering a "lost" species is not easy. It can require trips to remote areas and canvassing a large area in search of only a handful of animals. But new technology and stronger partnerships with local communities have helped these hidden, "uncharismatic" creatures come to light.

Shots Are Scary. But They Don't Have To Be.

According to the CDC, about one in four adults has a fear of needles. Many of those people say the phobia started when they were kids. For some people, the fear of needles is strong enough that they avoid getting important treatments, vaccines or tests. That poses a serious problem for public health. Researchers have helped develop a five step plan to help prevent what they call "needless pain" for kids getting injections or their blood drawn. Guest host Tom Dreisbach talks with Dr. Stefan Friedrichsdorf of UCSF Benioff Children's Hospitals, who works with a team to implement the plan at his own hospital. Friedrichsdorf told us some of the most important research on eliminating pain has come from researchers in Canada. Learn more about their work here. This episode was inspired by the reporting of our colleague April Dembosky, a journalist at member station KQED and KFF Health News. Read her digital story here.Got another question for a doctor?

The Evolutionary Mystery Of Menopause ... In Whales

Across the animal kingdom, menopause is something of an evolutionary blip. We humans are one of the few animals to experience it. But Sam Ellis, a researcher in animal behavior, argues that this isn't so surprising. "The best way to propagate your genes is to get as many offspring as possible into the next generation," says Ellis. "The best way to do that is almost always to reproduce your whole life." So how did menopause evolve? The answer may lie in whales. Ellis and his team at the University of Exeter recently published a study in the journal Nature that studies the evolution of menopause in the undersea animals most known for it. What they uncovered may even help explain menopause in humans. Curious about other animal behavior mysteries?

Syphilis Cases Are Rising In Babies. Illinois Has A Potential Solution

The number of newborns born with syphilis – a serious sexually transmitted infection – has skyrocketed 755% from 2012 to 2021. These babies have congenital syphilis, which is when the infection is passed from mother to baby during pregnancy. It can have dire consequences if left untreated. The surge has left medical professionals and public health leaders scrambling for solutions to stop the spread. Today on the show, Chicago based journalist Indira Khera talks to Emily Kwong about what's behind this mysterious public health crisis – and brings us inside Illinois' Perinatal Syphilis Warmline.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Nuclear fusion could one day change the world by producing energy at lower costs than we generate it now — without greenhouse gas emissions or long-term nuclear waste. If we can get it to work. People have been promising nuclear fusion as a new, clean source of power for decades without much tangible success. But lately, billions of dollars from venture capitalists and tech entrepreneurs have flowed into the field. Science correspondent Geoff Brumfiel shares his reporting on some of the companies racing towards what could be the world's first commercial fusion power plants.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

The "Shocking" Tactic Electric Fish Use to Collectively Sense the World

Neuroscientist Nathan Sawtell has spent a lot of time studying the electric elephantnose fish. These fish send and decipher weak electric signals, which Sawtell hopes will eventually help neuroscientists better understand how the brain filters sensory information about the outside world. As Sawtell has studied these electric critters, he's had a lingering question: why do they always seem to organize themselves in a particular orientation. At first, he couldn't figure out why, but a new study released this week in Nature may have an answer: the fish are creating an electrical network larger than any field a single fish can muster alone, and providing collective knowledge about potential dangers in the surrounding water.

The Recent Glitch Threatening Voyager 1

The Voyager 1 space probe is the farthest human-made object in space. It launched in 1977 with a golden record on board that carried assorted sounds of our home planet: greetings in many different languages, dogs barking, and the sound of two people kissing, to name but a few examples. The idea with this record was that someday, Voyager 1 might be our emissary to alien life – an audible time capsule of Earth's beings. Since its launch, it also managed to complete missions to Jupiter and Saturn. In 2012, it crossed into interstellar space. But a few months ago, the probe encountered a problem. "It's an elderly spacecraft," says NPR science correspondent Nell Greenfieldboyce, "and it had some kind of electronic stroke." Greenfieldboyce talks to Short Wave Host Regina G. Barber about the precarious status of Voyager 1 – the glitch threatening its mission, and the increasingly risky measures NASA is taking to try and restore it.

The Evolution Of Cancer Treatment

Recently, the US Food and Drug Administration approved a first-of-its-kind cancer therapy to treat aggresive forms of skin cancer. It has us thinking of the long history of cancer. One of the first recorded mentions of cancer appears in an ancient Egyptian text from around 3000 B.C. And although we now know much more about how cancer begins — as a series of mutations in someone's DNA — it's a disease people are still grappling with how to cure cancers today. This episode, cancer epidemiologist Mariana Stern talks about cancer history and treatment today — plus, why some people are more prone to certain cancers and why that might matter for curing them.Want to hear about advances in medicine?

Could Dune Really Exist? What Scientists Think of Our Favorite Sci-Fi Worlds

The sci-fi film Dune: Part Two is out in theaters now. The movie takes place on the harsh desert planet, Arrakis, where water is scarce and giant, killer sandworms lurk just beneath the surface. But what do planetary scientists and biologists think about the science of these worms, Arrakis and our other favorite sci-fi planets? Today on the show, Regina G. Barber talks to biologist (and Star Trek consultant!) Mohamed Noor and planetary scientist Michael Wong about Dune, habitable planets and how to make fantasy seem more realistic.

Is It Possible To Feed The World Sustainably?

According to the United Nations, about ten percent of the world is undernourished. It's a daunting statistic — unless your name is Hannah Ritchie. She's the data scientist behind the new book Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet. It's a seriously big thought experiment: How do we feed everyone on Earth sustainably? And because it's just as much an economically pressing question as it is a scientific one, Darian Woods of The Indicator from Planet Money joins us. With Hannah's help, Darian unpacks how to meet the needs of billions of people without destroying the planet.Questions or ideas for a future show?

In Light of The Alabama Court Ruling, A Look At The Science Of IVF

An Alabama Supreme Court ruling that frozen embryos can be considered "extrauterine children" under state law has major implications for how in vitro fertilization, commonly called IVF, is performed. Since the first successful in vitro fertilization pregnancy and live birth in 1978, nearly half a million babies have been born using IVF in the United States. Reproductive endocrinologist Amanda Adeleye explains the science behind IVF, the barriers to accessing it and her concerns about fertility treatment in the post-Roe landscape.Read more about the science of IVF.Questions or ideas for a future episode of Short Wave?

Didn't Get A Valentine's Love Song? These Skywalker Gibbons Sing Love Duets

In the green tree canopies of forested areas in Myanmar, you might wake up to the sounds of gibbons singing love songs. Gibbons start their day with passionate duets and, though these love songs may sound a little different than the ones in your playlists, they just helped researchers figure out that Myanmar has the largest population of an endangered gibbon species on Earth. They're called skywalker gibbons, and until recently, scientists thought there were fewer than 200 of them – all living in southwestern China. Want to hear us cover more animal news?

When The Sun Erupts

We are at the height of the Sun's activity in its eleven year cycle, known to astronomers as the solar maximum. This means that over the next several months there's going to be a lot of solar activity. It's got us thinking back to 1859. That's when astronomer Richard Carrington was studying the Sun when he witnessed the most intense geomagnetic storm recorded in history. The storm, triggered by a giant solar flare, sent brilliant auroral displays across the globe causing electrical sparking and fires in telegraph stations. This encore episode, Regina talks to solar physicist Dr. Samaiyah Farid about what's now known as the Carrington event and about what may happen the next time a massive solar storm hits Earth.Want to hear us cover other parts of the solar system?

The Life And Death Of A Woolly Mammoth

Lately, paleoecologist Audrey Rowe has been a bit preoccupied with a girl named Elma. That's because Elma is ... a woolly mammoth. And 14,000 years ago, when Elma was alive, her habitat in interior Alaska was rapidly changing. The Ice Age was coming to a close and human hunters were starting early settlements. Which leads to an intriguing question: Who, or what, killed her? In the search for answers, Audrey traces Elma's life and journey through — get this — a single tusk. Today, she shares her insights on what the mammoth extinction from thousands of years ago can teach us about megafauna extinctions today with guest host Nate Rott.

The U.N.'s First-Ever Analysis Of World's Migratory Species Just Dropped

Every year, billions of animals across the globe embark on journeys. They fly, crawl, walk or slither – often across thousands of miles of land or water – to find better food, more agreeable weather or a place to breed. Think monarch butterflies, penguins, wild Pacific salmon. These species are crucial to the world as we know it. But until this week, there has never been an official assessment of the world's migratory animals. So today on the show, correspondent Nate Rott shares the first-ever report on state of the world's migratory animals – the threats facing them and what can be done to help. Are you afraid of needles or shots? Send us a voice memo with your story at [email protected]. We'd love to hear about it for an upcoming episode.

The Shared History Of The Chinese And Gregorian Calendars

Happy Lunar New Year! According to the Chinese lunisolar calendar, the new year began Saturday. For many, like our host Regina G. Barber, this calendar and its cultural holidays can feel completely detached from the Gregorian calendar. Growing up, she associated the former with the Spring Festival and getting money in red envelopes from relatives, and the other with more American traditions. But the Chinese calendar has a deep, centuries-long shared history with the Gregorian calendar. To learn more about this shared history, Gina talks to scientists and historians, who spill the tea about the science behind calendars, and how both calendars and the Chinese Lunar New Year celebration played a key role in the rise and fall of empires.

Clownfish Might Be Counting Their Potential Enemies' Stripes

At least, that's what a group of researchers at the Okinawa Institute of Science and Technology Graduate University thinks. The team recently published a study in the journal Experimental Biology suggesting that Amphiphrion ocellaris, or clown anemonefish, may be counting. Specifically, the authors think the fish may be looking at the number of vertical white stripes on each other as well as other anemonefish as a way to identify their own species. Not only that — the researchers think that the fish are noticing the minutiae of other anemonefish's looks because of some fishy marine geopolitics.

After 20 Years, This Scientist Uncovered The Physics Behind The Spiral Pass

If you've ever watched part of a professional football game, you've probably seen a tight spiral pass. Those perfect throws where the football leaves the player's hand and neatly spins as it arcs through the air. But those passes? They seem to defy fundamental physics. And for a long time, scientists couldn't figure out exactly why — until experimental atomic physicist Tim Gay cracked the case just a few years ago. His answer comes after two decades of hobby research and more than a couple late night shouting matches with two other physicists over Zoom.Today on Short Wave, host Regina G. Barber talks to Tim about this football mystery — and the physics behind the game.Listen to Short Wave on Spotify, Apple Podcasts and Google Podcasts.

Wolves Are Thriving In The Radioactive Chernobyl Exclusion Zone

In 1986 the Chernobyl nuclear power plant exploded, releasing radioactive material into northern Ukraine and Belarus. It was the most serious nuclear accident in history. Over one hundred thousand people were evacuated from the surrounding area. But local gray wolves never left — and their population has grown over the years. It's seven times denser than populations in protected lands elsewhere in Belarus. This fact has led scientists to wonder whether the wolves are genetically either resistant or resilient to cancer — or if the wolves are simply thriving because humans aren't interfering with them. This episode, researchers Shane Campbell-Staton and Cara Love talk through what might be causing this population boom. Plus, why researchers in the field of human cancer are eager to collaborate with them.Want to hear about other ways humans are impacting the planet? Email us at [email protected].

This Scientist Figured Out Why Your Appendix Isn't Useless

Back in the day, many of us heard that the appendix is a vestigial organ — at best, a body part that lost its purpose all those many years ago. At worst, an unnecessary clinger-on to the human body that, when ruptured, could be life threatening. But what if that narrative is wrong?Heather Smith became obsessed with the appendix after hers was removed at age 12. After years of anatomy research, she's found that the appendix is not, in fact, useless. Reporter Selena Simmons-Duffin is in the host chair today to get the scoop on all things appendix.

Murder, Mayhem At The Zoo: A Naked Mole Rat Succession War

An all-out "naked mole rat war" has broken out at Smithsonian's National Zoo, after the queen of the colony was mortally wounded by one of her own children. Short Wave's Pien Huang and Margaret Cirino visit the battleground – a series of deceptively calm-looking plexiglass enclosures at the Zoo's Small Mammal House. There, the typically harmonious, eusocial rodents are now fighting their siblings with their big front teeth to determine who will become the new queen. Pien and Marge talk with zookeeper Kenton Kerns about what led to this violent succession drama, the stress he feels in witnessing his first naked mole rat war and how he hopes it will resolve.

Choose Your Lightning Protection: Lasers, Rockets or Rods?

Every year, lightning is estimated to cause up to 24,000 deaths globally. It starts forest fires, burns buildings and crops, and causes disruptive power outages. The best, most practical technology available to deflect lightning is the simple lightning rod, created by Benjamin Franklin more than 250 years ago. But lightning rods protect only a very limited area proportional to their height. In today's encore episode, we explore why a group of European researchers are hoping the 21 century upgrade is a high-powered laser.

Lessons on the limits of ecosystem restoration from the Everglades

When the U.S. government and state of Florida unveiled a new plan to save the Everglades in 2000, the sprawling blueprint to restore the wetlands became the largest hydrological restoration effort in the nation's history. Two decades later, only one project is complete, the effort is $15 billion over budget and the Everglades is still dying. The new podcast Bright Lit Place from WLRN and NPR heads into the swamp to meet its first inhabitants, the scientists who study it and the warring sides struggling to find a way out of the muck. Today, we hear an excerpt as environment reporter Jenny Staletovich tags along with wetlands ecologist Evelyn Gaiser to the remotest part of the swamp.

When Tiny, Invasive Ants Go Marching In...And Alter An Ecosystem

At the Ol Pejeta Conservancy, a wildlife preserve in central Kenya, lions and cheetahs mingle with zebras and elephants across many miles of savannah – grasslands with "whistling thorn" acacia trees dotting the landscape here and there. Twenty years ago, the savanna was littered with them. Then came invasive big-headed ants that killed native ants — and left the acacia trees vulnerable. Over time, elephants have knocked down many of the trees. That has altered the landscape — and the diets of other animals in the local food web.Curious about other science news?

Experiencing Racism May Physically Change Your Brain

Scientists know that Black people are at a greater risk for health problems like heart disease, diabetes and Alzheimer's disease than white people. A growing body of research shows that racism–in health systems and the effects of experiencing racial discrimination–contributes to these long-standing health disparities for Black communities. Now, some researchers are asking whether part of the explanation involves how racism changes the brain. Today on the show, science correspondent Jon Hamilton speaks with Nate Harnett, an assistant professor of psychiatry at Harvard Medical School, and Negar Fani, a clinical neuroscientist at Emory University about how experiencing racism may change the brain.

After Domestic Abuse Ends, the Effects of Brain Injuries Can Persist

At least one in four women — and a much smaller proportion of men — experiences intimate partner violence in their lifetime. For people in violent relationships, brain injuries are unfortunately common. But little is known about what exactly happens inside the brains of people dealing with domestic violence — and how these kinds of traumatic brain injuries may be different from those that come out of contact sports like football. Host Regina G.

Our Lives Are Ruled By The Illusion Of Time

Time is a concept so central to our daily lives. Yet, the closer scientists look at it, the more it seems to fall apart. Time ticks by differently at sea level than it does on a mountaintop. The universe's expansion slows time's passage. "And some scientists think time might not even be 'real' — or at least not fundamental," says NPR science correspondent Geoff Brumfiel. In this encore episode, Geoff joins Short Wave Scientist in Residence Regina G. Barber to bend our brains with his learnings about the true nature of time. Along the way, we visit the atomic clocks at the National Institute of Standards and Technology, consider distant exploding stars and parse the remains of subatomic collisions.

Body Electric: The Body Across The Ages

If you work at home or in an office, you might spend a lot of your day sitting down and staring at a computer screen. That can have lots of negative effects – but it's hard to carve out significant time in the day to counteract that.Our friends at NPR's TED Radio Hour wanted to know if small, frequent movement breaks might do the trick instead. Along with Columbia University Medical Center, they conducted a study of over 20,000 listeners and asked them to incorporate these movement breaks into their day. Today on the show, TED Radio Hour's Manoush Zomorodi digs into the surprising preliminary results with Columbia University researcher Keith Diaz. Ideas to get moving? We want to hear them!

Odd Radio Circles Are glowing Around Some Galaxies. Now We Know Why

Since they were discovered in 2019, strange, glowing circles of light in space have mystified researchers. Now called odd radio circles, or ORCs, these rings of light sit in the radio portion of the electromagnetic spectrum. They pulse out of the centers of some galaxies – and until now, no one knew why.In this episode, host Regina G. Barber talks to Alison Coil, a professor of astronomy and astrophysics at University of California San Diego, about her latest research. They break down what ORCs are, where they come from and what they might reveal about how galaxies evolve over billions of years.Wondering about other happenings across the universe?

Preserving Our Humanity In The Age Of Robots

Human beings are hardwired for social connection – so much so that we think of even the most basic objects as having feelings or experiences. (Yup, we're talking to you, Roomba owners!) Social robots add a layer to this. They're designed to make us feel like they're our friends. They can do things like care for children, the elderly or act as partners. But there's a darker side to them, too. They may encourage us to opt out of authentic, real-life connections, making us feel more isolated. Today on the show, host Regina G. Barber explores the duality of social robots with Eve Herold, author of the new book Robots and the People Who Love Them: Holding on to Our Humanity in an Age of Social Robots.

The Record For World's Largest Snowflake Might Not Count

A winter storm brought heavy rain and snow to parts of the East Coast this weekend, which got us thinking about snowflakes. Those intricate, whimsical crystals are a staple of magical wintry scenes, but how big can they really get? Well, according to the Guinness World Record keepers, the "largest snowflake" ever recorded was a whopping 15 inches in diameter. It was spotted near Missoula, Montana in 1887. But Kenneth Libbrecht, a physicist at Caltech, has long been skeptical of that record. So he set out to find what makes a snowflake a snowflake and whether that 1887 record is scientifically possible. You can read more about what he discovered here.Want to share the snowflakes you've spotted this winter? Email us a photo at [email protected].

Snow Flies Pay An Arm And A Leg For Love

The winter is usually when insects die or go into a state of paused development, but for tiny specks on the white snow called snow flies, it's time to run around, find a lover and make baby snow flies. Neuroscientist John Tuthill has been studying these creatures since he first came across them in 2016. He's found that not only can they survive in the cold, but if one of their limbs starts to freeze, they can self-amputate and pop it right off. That buys the snow fly time to find a mate and make sweet, sweet snow fly love.Interested in other winter biology? Email us at [email protected] — we'd love to hear from you!

Asian Glow Might Have A Major Upside

Ever gotten a scarlet, hot face after drinking? Or know someone who has? Many people felt it as they ring in the New Year with champagne toasts. That's because this condition, commonly called "Asian flush" or "Asian glow," affects an estimated half a BILLION people, who can't break down aldehyde toxins that build up in their bodies. But what if there's a benefit to having Asian glow? Katie Wu, a staff writer for The Atlantic, has looked into the research a theory as to why the condition might have been a powerful tool for some of our ancestors to survive disease.

Life Could Be Different ... And Maybe Better?

Are people ever satisfied? Two social psychologists, Ethan Ludwin-Peery and Adam Mastroianni, fell down a research rabbit hole accidentally answering a version of this very question. After conducting several studies, the pair found that when asked how things could be different, people tend to give one kind of answer, regardless of how the question is asked or how good life felt when they were asked. Short Wave's Scientist in Residence Regina G. Barber digs into the research—and how it might reveal a fundamental law of psychology about human satisfaction. (encore)

Once A Satirical Conspiracy, Bird Drones Could Soon Be A Reality

Millions of people in the U.S. are bird watchers. But a couple of years ago a satirical conspiracy theory gained popularity because of an absurd claim: That those birds were also watching people. Now, rather than being the stuff of internet memes, some engineers are, in fact, trying to reverse engineer how birds fly to eventually take what they learn to create more efficient bird-like drones. Today on the show, host Regina G. Barber talks to reporter Anil Oza about how scientists are using real birds to make fake ones. Want to learn more about innovations in science?

Climate Talks Call For A Transition Away From Fossil Fuels. Is That Enough?

For the first time in its history, the United Nations climate conference concluded with a call to transition away from fossil fuels. But not all of the nearly 200 countries present at the meeting, known as COP28, were happy with the final agreement. Critics of the agreement had instead called for a clear path towards phasing out fossil fuels and pointed out a "litany of loopholes" in the final text. This episode, we look at the tensions and breakthroughs of the conference — and how far behind we are in limiting the devastating impacts that could be on the way.

More Plant And Fungi Emojis, Please!

A team of conservation biologists from Italy recently found that current emoji options are sorely lacking when it comes to life outside of vertebrates in the animal kingdom. Sure, there are multiple dog and cat options to choose from. But when it comes to fungi, for example, the choices are limited ... to one. The study was published this week in the journal iScience argues that our emoji lexicon is in dire need of some biodiversity – which could have a real impact on the way people communicate about conservation.

When AI Goes Wrong

Artificial intelligence is increasingly being used throughout the world to predict the future. Banks use it to predict whether customers will pay back a loan, hospitals use it to predict which patients are at greatest risk of disease and auto insurance companies use it determine rates by predicting how likely a customer is to get in an accident. But issues like data leakage and sampling bias can cause AI to give faulty predictions, to sometimes disastrous effects. That's what we get into today: the hazards of AI.Want to hear more of the latest research on AI? Email us at [email protected] — we might answer your question on a future episode!

Why it's so hard to resist holiday sales (and how to try)

Malls are designed to overwhelm our brains. Add the stress of holiday shopping, and a quick trip to pick up presents could turn into an hours-long shopping spree thanks to all the ways stores use research from fields like consumer neuroscience and neuromarketing to entice you. Retailers create urgency and scarcity to push you to give into the emotional part of your brain, motivated by the release of dopamine. But we've got your back! With the help of NPR business correspondent Alina Selyukh, we get into the psychology of sales and discounts: Why it's SO hard to resist the tricks stores use — and some tips to outsmart them.

How Glaciers Move — And Affect Sea Level Rise

Glaciers like the ones in Greenland are melting due to climate change, causing global sea levels to rise. That we know. But these glaciers are also moving. What we don't know is just how these two processes – melting and movement – interact and ultimately impact how quickly sea levels will rise. This encore episode, Jessica Mejía, a postdoctoral researcher in glaciology at the University of Buffalo, explains what it's like to live on a glacier for a month and what her research could mean for coastal communities all over the world.Curious about other research happening around the globe?

Feeling Lonely? Your Brain May Process The World Differently

The U.S. is in the midst of a loneliness epidemic. And for a lot of people, the feeling is even more pronounced during the holidays. In addition to its emotional impact, chronic loneliness and social isolation have some dramatic health consequences: increased risk of heart disease and stroke, infections, cancer, even premature death. Recent research also suggests that loneliness can change the way people process the world. So today on the show, host Regina G. Barber talks to Rachel Carlson about the neuroscience of loneliness.

A Star Is Born ... And Then What? Journey Through The Life Cycle of a star

Soon after the sun sets on winter nights, if you live in the northern hemisphere you can look into the sky and find the Orion constellation near the eastern horizon. Astrophysicist Sarafina El-Badry Nance has always been drawn to a particular star in Orion: Betelgeuse, a red supergiant nearing the end of it's life on the hunter's left shoulder. But what stages of life did Betelgeuse — or any star — go through before it reached this moment? Regina G.

Don't Call It Dirt: The Surprising Science Of Soil

It's easy to overlook the soil beneath our feet, or to think of it as just dirt to be cleaned up. But soil wraps the world in an envelope of life: It grows our food, regulates the climate and makes the planet habitable. "What stands between life and lifelessness on our planet Earth is this thin layer of soil that exists on the Earth's surface," says Asmeret Asefaw Berhe, a soil scientist at the University of California-Merced. In honor of World Soil Day tomorrow, we're revisiting our conversation with Prof. Berhe, who is also serving as Director of the U. S. Dept. of Energy's Office of Science. She talks to Aaron about the hidden majesty of soil and why it's crucial to tackling the climate crisis.

These Penguins Take 10,000 Little Naps A Day — Seconds At A Time

Sleep. It's an essential biological function that has long intrigued scientists. Researchers have studied everything from mice to fruit flies in the lab to get a better understanding of what happens when animals sleep — and why so many do it. This week, scientists finally added one piece to the elusive sleep puzzle: How wild chinstrap penguins sleep amid their noisy colony. Turns out, they do it over 10,000 times in seconds-long bursts throughout the day — totaling 11 hours when all is said and done.

The goal of IVG is to make unlimited supplies of what Hayashi calls "artificial" eggs and sperm from any cell in the human body. That could let anyone — older, infertile, single, gay, trans — have their own genetically related babies. As such, the field opens up a slew of ethical concerns. But that isn't stopping researchers from pressing forward. So, this episode NPR science correspondent Rob Stein gives us a glimpse into the global race to create the first artificial human embryos to see how the competition is unfolding.

Monday Night Football And Pursuing Two Careers With John Urschel

As kids, some of us dream of multiple careers: being an astronaut AND the next president. Or digging up dinosaurs AND selling out concert stadiums. As we get older, there's pressure to pick one path. But what if we didn't have to? After all, John Urschel didn't. He's a mathematician and professor at MIT. But before that, he played football for the Baltimore Ravens. Today on the show, Monday night football! Host Regina G. Barber talks to Urschel about linear algebra and following his dream of becoming a mathematician while living the dream as a NFL player.

What Fossilized Poop Can Teach Us About Dinosaurs

Walking into Karen Chin's office at the University of Colorado, Boulder, one of the first things you might notice is that petrified poops are everywhere. They're in shallow boxes covering every surface and filling up shelves, cabinets and drawers. She's a leading expert in the fossils, known as coprolites. They delight her because of what they reveal about the ancient eating habits and food webs of dinosaurs — rare insights for the paleontology world. This episode, she talks with Short Wave co-host Aaron Scott about the lessons scientists can learn from ancient poopetrators.Interested in learning more ancient or scatological mysteries of science?

Thousands of earthquakes in Iceland may spell a volcanic eruption

Saturday, the entire coastal town of Grindavik, Iceland was evacuated. That's because over the weekend, the country experienced nearly 2,000 earthquakes within 48 hours. And they've kept coming since then – in swarms. Scientists think the quakes are indicative of magma moving closer to the surface in the country's southwestern peninsula and that a local volcano could erupt at any moment. Today on the show, host Regina G. Barber talks to volcanologist Diana Roman about the science behind these earthquakes. Got science to share? Email us at [email protected].

How Venus got caught up in an 18th century space race

In the 18th century the world was focused on Venus. Expeditions were launched in pursuit of exact measurements of Venus as it passed between Earth and the Sun. By viewing its journey and location on the Sun's surface, scientists hoped to make a massive leap in scientific knowledge. With a little help from math, Scientist in Residence Regina G. Barber recounts how humanity came closer to understanding our cosmic address — and relative distances to other planets — in the solar system.

Mapping The Seafloor Is Daunting But Key To Improving Human Life

Scientists have mapped less than 25% of the world's seafloor. Experts say that getting that number up to 100% would improve everything from tsunami warnings to the Internet and renewable energy. That's why there's currently a global effort to create a full, detailed map of the seabed by 2030. Today, we talk to Dawn Wright, a marine geographer and chief scientist at the Environmental Systems Research Institute about this effort.Curious about ocean science? Email us at [email protected].

Pulling An All-Nighter Is A Temporary Antidepressant

What your parents didn't tell you about pulling an all-nighter? It just might ease depression for several days. At least, that's what researchers found happens to mice in a study published in the journal Neuron Thursday. Most people who've stayed up all night know the "tired and wired" feeling they get the next day. Scientists know this feeling can have a strong antidepressant effect in people that lasts for several days, even after the other changes wear off. But this new study may help researchers figure out why sleeplessness causes this effect. Plus, we get into some other science headlines we can't stop talking about: Turning a centuries-old debate over starfish on its head and record lows for Antarctica's sea ice. Got science to share?

Thanks, Neanderthals: How our ancient relatives could help find new antibiotics

Antibiotics have changed the world. They've made it possible to treat diseases that used to mean anything from discomfort to death. But no new classes of antibiotics have made it to the market since the 1980s. What if humans' closest, ancient relatives held the answer to antibiotic resistance? Some scientists want to discover new antibiotics using machine learning ... and some very, very old relatives of humans. Host Aaron Scott talks to César de la Fuente about using computers to discover the first therapeutic molecules in extinct organisms. Have a question? Email us at [email protected].

How Climate Change Is Testing The Endangered Species Act

Some people keep dogs in their backyards. In the Florida Keys, some residents have deer the size of a golden retriever in their yards. As sea levels rise and salt water climbs higher on the islands, it's shrinking habitat for this deer — which already has an estimated population of at most 1,000. Today, host Regina G. Barber hears from reporters Nate Rott and Ryan Kellman about the Key deer, and how rising sea levels are forcing wildlife managers to ask big questions about the future of the subspecies. In this episode, we incorrectly stated that Valerie Preziosi is the founder of Key Deer Alliance. In fact, she is the founder and director of the organization Save Our Key Deer.

Choose Your Own Adventure — But Make It Math

Ever read those Choose Your Own Adventure books of the '80s and '90s? As a kid, mathematician Pamela Harris was hooked on them. Years later she realized how much those books have in common with her field, combinatorics, the branch of math concerned with counting. It, too, depends on thinking through endless, branching possibilities. So, she and several of her students set out to write a scholarly paper in the style of Choose Your Own Adventure books. In this encore episode, Dr. Harris tells host Regina G. Barber all about how the project began, how it gets complicated when you throw in wormholes and clowns, and why math is fundamentally a creative act.

Why Chilean Mummies Are Decomposing After 7,000 Years

Here on Short Wave, we're getting into the Halloween spirit a little early with a look at the world's oldest mummies. They're found in modern-day northern Chile. The mummies are well-preserved, so over the past 7,000 years, some have been exhumed for scientific study. But recently, something startling happened: Some of the mummies started to decompose. Today on the show, Regina G. Barber talks to archeologist Marcela Sepulveda about the civilization that made these mummies: the Chinchorro people. We dig into the science behind their mummification techniques and how the changing planet is affecting archeologists' ability to study the past. Fascinated by a science mystery?

As the blooms have grown, so too has their impact on coastal communities. The stinky seaweed can wreck local economies and ecosystems — and even threaten human health, some research suggests. But the creators of the AlgaRay say that their robot might do more than halt this damage. It could also fight climate change.This week NPR is doing something new — dedicating an entire week to stories and conversations about the search for climate solutions.

The Tiny Worm At The Heart Of Regeneration Science

A tiny worm that regenerates entire organs. A South American snail that can regrow its eyes. A killifish that suspends animation in dry weather and reanimates in water. These are the organisms at the heart of regeneration science. But exactly how they do these things is still a mystery to scientists. Today on the show, Regina G. Barber talks to microbiologist Alejandro Sánchez Alvarado about this mystery. They get into what regeneration looks like, why humans can't do it (yet) and where the science may lead us in the decades to come.

Osiris-REx and the quest to understand the solar system's origin

In 2016, NASA launched a spacecraft to do something rarely attempted before: Collect space rocks from a potentially dangerous asteroid. The mission, named OSIRIS-REx, was successful. Tuesday, scientists opened a sealed canister containing the samples from the asteroid Bennu. Science correspondent Nell Greenfieledboyce talks to host Regina G. Barber about the mission's close calls and what NASA might learn from these space rocks that are older than our planet.

Itchy? Here's why

Ever had an itch you can't scratch? It can be maddening. And even though itch has a purpose — it's one of our bodies' alert systems — it can also go very wrong. Dermatologist Dr. Shawn Kwatra talks to host Regina G. Barber about the science of why and how we get itchy, the mysteries behind chronic itch and how his own experience with eczema, hives and seasonal allergies helps him connect with his patients.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Why Sustainable Seafood Is A Data Problem

The last several decades have taken a toll on the oceans: Some fish populations are collapsing, plastic is an increasing problem and climate change is leading to coral bleaching — as well as a host of other problems. But marine biologist and World Economic Forum programme lead Alfredo Giron says there's room to hope for the seas. He works to create systems that governments and the fishing industry can use to make sure fishing is legal and sustainable so oceans thrive for years to come. In this encore episode, he talks to host Aaron Scott about his work and how managing the ocean is a lot about managing people.We spoke to Alfredo Giron about his research and thoughts, the episode is not meant to reflect the World Economic Forum's positions.Have questions about the world around you?

The James Webb Space Telescope Is Fueling Galactic Controversy

We're entering a new era of astrophysics. The James Webb Space Telescope is helping scientists test existing ideas and models of how the universe was created—on a whole new level. This telescope is sending back images of galaxies forming under a billion years after the Big Bang—way earlier than astronomers had previously expected. Not only that, scientists had anticipated that later—but still very early—galaxies would be small, barely formed blobs; instead, the galaxies in these images have spiral arms. So, today's show is all about GALACTIC CONTROVERSY! Computational astrophysicist Jorge Moreno talks with fellow astronomer and Short Wave's Scientist in Residence Regina G. Barber about how these new findings are stirring up controversy in the scientific community and the lessons we can learn from galaxies. Questions or controversies? Email us at [email protected].

The Latest COVID Booster Is Here. Should You Get It?

This week, the Food and Drug Administration approved new COVID vaccines this week. It comes at a time when COVID cases, hospitalizations and deaths are on the rise. It's also the first time that the federal government is not paying for the vaccines. Given this confluence of events, we huddled with our colleagues, intrepid health correspondents Maria Godoy and Rob Stein. They gave us the lowdown on the CDC's recommendations for who should get it, how protective the booster is, how to access it regardless of your insurance status—and even how time this booster with other vaccines that may be on your radar.Check out Rob and Maria's full COVID booster Q&A here.
