We eat eels in sushi, stews, and pasta. Eels eat anything. Also they can survive outside of water for hours and live for up to 80 years. But this slippery snake of the sea harbors an even deeper mystery, one that has tormented the minds of Aristotle and Sigmund Freud and apparently the entire country of Italy: Where do they come from? We travel from the estuaries of New York to the darkest part of the ocean in search of the limits of human knowledge.

In the early 60s, Robert Axelrod was a math major messing around with refrigerator-sized computers. Then a dramatic global crisis made him wonder about the space between a rock and a hard place, and whether being good may be a good strategy. With help from Andrew Zolli and Steve Strogatz, we tackle the prisoner’s dilemma, a classic thought experiment, and learn about a simple strategy to navigate the waters of cooperation and betrayal. Then Axelrod, along with Stanley Weintraub, takes us back to the trenches of World War I, to the winter of 1914, and an unlikely Christmas party along the Western Front.

More often than not, a fight is just a fight... Someone wins, someone loses. But this hour, we have a series of face-offs that shine a light on the human condition, the benefit of coming at something from a different side, and the price of being right.

Nate DiMeo was preoccupied with the past, and how we relate to it, from a very young age. For the last decade or so he's been scratching this itch with The Memory Palace, a podcast he created. He does things very differently than we do, but his show has captured the hearts of Radiolab staffers, past and present, time and time again.

So we decided to get Nate into the studio to share a few of his episodes with us and talk to us about how and why he does what he does. He brought us stories about the Morse Code, the draft lottery, and then he hit us with a brand new episode about a bull on trial, that bounces off a story we did pretty recently.

More history on scrub bulls.

In an online world, that story about you lives forever. The tipsy photograph of you at the college football game? It’s up there. That news article about the political rally you were marching at? It’s up there. A DUI? That’s there, too. But what if ... it wasn’t.

In Cleveland, Ohio, a group of journalists are trying out an experiment that has the potential to turn things upside down: they are unpublishing content they’ve already published. Photographs, names, entire articles. Every month or so, they get together to decide what content stays, and what content goes. On today’s episode, reporter Molly Webster goes inside the room where the decisions are being made, listening case-by-case as editors decide who, or what, gets to be deleted. It’s a story about time and memory; mistakes and second chances; and society as we know it.

On the inaugural episode of More Perfect, we explore three little words embedded in the 8th Amendment of the U.S. Constitution: “cruel and unusual.” America has long wrestled with this concept in the context of our strongest punishment, the death penalty. A majority of “we the people” (61 percent, to be exact) are in favor of having it, but inside the Supreme Court, opinions have evolved over time in surprising ways.

And outside of the court, the debate drove one woman in the UK to take on the U.S. death penalty system from Europe. It also caused states to resuscitate old methods used for executing prisoners on death row. And perhaps more than anything, it forced a conversation on what constitutes cruel and unusual punishment.

This episode begins with a rant. This rant, in particular, comes from Dan Engber - a science writer who loves animals but despises animal intelligence research. Dan told us that so much of the way we study animals involves tests that we think show a human is smart ... not the animals we intend to study.

Dan’s rant got us thinking: What is the smartest animal in the world? And if we threw out our human intelligence rubric, is there a fair way to figure it out?

Obviously, there is. And it’s a live game show, judged by Jad, Robert … and a dog.

For the last episode of G, Radiolab’s miniseries on intelligence, we’re sharing that game show with you. It was recorded as a live show back in May 2019 at the Greene Space in New York City. We invited two science writers, Dan Engber and Laurel Braitman, and two comedians, Tracy Clayton and Jordan Mendoza, to compete against one another to find the world’s smartest animal. What resulted were a series of funny, delightful stories about unexpectedly smart animals and a shift in the way we think about intelligence across all the animals - including us.

This past fall, a scientist named Steve Hsu made headlines with a provocative announcement. He would start selling a genetic intelligence test to couples doing IVF: a sophisticated prediction tool, built on big data and machine learning, designed to help couples select the best embryo in their batch. We wondered, how does that work? What can the test really say? And do we want to live in a world where certain people can decide how smart their babies will be?

When a law student named Mark Bold came across a Supreme Court decision from the 1920s that allowed for the forced sterilization of people deemed “unfit,” he was shocked to discover that it had never been overturned. His law professors told him the case, Buck v Bell, was nothing to worry about, that the ruling was in a kind of legal limbo and could never be used against people. But he didn’t buy it. In this episode we follow Mark on a journey to one of the darkest consequences of humanity’s attempts to measure the human mind and put people in boxes, following him through history, science fiction and a version of eugenics that’s still very much alive today, and watch as he crusades to restore a dash of moral order to the universe.

Albert Einstein asked that when he died, his body be cremated and his ashes be scattered in a secret location. He didn’t want his grave, or his body, becoming a shrine to his genius. When he passed away in the early morning hours of April, 18, 1955, his family knew his wishes. There was only one problem: the pathologist who did the autopsy had different plans.

In the third episode of “G”, Radiolab’s miniseries on intelligence, we go on one of the strangest scavenger hunts for genius the world has ever seen. We follow Einstein’s stolen brain from that Princeton autopsy table, to a cider box in Wichita, Kansas, to labs all across the country. And eventually, beyond the brain itself entirely. All the while wondering, where exactly is the genius of a man who changed the way we view the world?

In the first episode of G, Radiolab’s miniseries on intelligence, we went back to the 1970s to meet a group of Black parents who put the IQ test on trial. The lawsuit, Larry P v Riles, ended with a ban on IQ tests for all Black students in the state of California, a ban that’s still in place today.

This week, we meet the families in California dealing with that ban forty years later. Families the ban was designed to protect, but who now say it discriminates against their children. How much have IQ tests changed since the 70s? And can they be used for good? We talk to the people responsible for designing the most widely used modern IQ test, and along the way, we find out that at the very same moment the IQ test was being put on trial in California, on the other side of the country, it was being used to solve one of the biggest public health problems of the 20th century.

Are some ideas so dangerous we shouldn’t even talk about them? That question brought Radiolab’s senior editor, Pat Walters, to a subject that at first he thought was long gone: the measuring of human intelligence with IQ tests. Turns out, the tests are all around us. In the workplace. The criminal justice system. Even the NFL. And they’re massive in schools. More than a million US children are IQ tested every year.

We begin Radiolab Presents: “G” with a sentence that stopped us all in our tracks: In the state of California, it is off-limits to administer an IQ test to a child if he or she is Black. That’s because of a little-known case called Larry P v Riles that in the 1970s … put the IQ test itself on trial. With the help of reporter Lee Romney, we investigate how that lawsuit came to be, where IQ tests came from, and what happened to one little boy who got caught in the crossfire.

How a sunken nuclear submarine, a crazy billionaire, and a mechanical claw gave birth to a phrase that has hounded journalists and lawyers for 40 years and embodies the tension between the public’s desire for transparency and the government’s need to keep secrets.

On a Tuesday afternoon back in the summer of 2017, Scotty Hatton and Scottie Wightman both made a decision to help someone in need. They both paid a price for their actions that day, which have led to a legal, moral, and scientific puzzle about how we balance accountability and forgiveness.

In this episode, we go to Bath County, Kentucky, where, as one health official put it, opioids have created “a hole the size of Kentucky.” We talk to the people on all sides of this story about stemming the tide of overdoses, we wrestle with the science of poison and fear, and we try to figure out when the drive to protect and help those around us should rise above the law.

Back in 2003 Belgium was holding a national election. One of their first where the votes would be cast and counted on computers. Thousands of hours of preparation went into making it unhackable. And when the day of the vote came, everything seemed to have gone well. That was, until a cosmic chain of events caused a single bit to flip and called the outcome into question.

Today on Radiolab, we travel from a voting booth in Brussels to the driver's seat of a runaway car in the Carolinas, exploring the massive effects tiny bits of stardust can have on us unwitting humans.

This week we’re going back to a favorite episode from 2015.

During World War II, something happened that nobody ever talks about. This is a tale of mysterious balloons, cowboy sheriffs, and young children caught up in the winds of war. And silence, the terror of silence.

Reporters Peter Lang-Stanton and Nick Farago tell us the story of a seemingly ridiculous, almost whimsical series of attacks on the US between November of 1944 and May of 1945. With the help of writer Ross Coen, geologist Elisa Bergslien, and professor Mike Sweeney, we uncover a national secret that led to tragedy in a sleepy logging town in south central Oregon.

In 1903 the US Supreme Court refused to say that Isabel González was a citizen of the United States. Then again, they said, she wasn’t a exactly an immigrant either. And they said that the US territory of Puerto Rico, Isabel’s home, was “foreign to the United States in a domestic sense.” Since then, the US has cleared up at least some of the confusion about US territories and the status of people born in them.

But, more than a hundred years later, there is still a US territory that has been left in limbo: American Samoa. It is the only place on earth that is US soil, but people who are born there are not automatically US citizens. When we visit American Samoa, we discover that there are some pretty surprising reasons why many American Samoans prefer it that way.

Our lives are filled with loops that hurt us, heal us, make us laugh, and, sometimes, leave us wanting more. This hour, Radiolab revisits the strange things that emerge when something happens, then happens again, and again, and again, and again, and again, and… well, again.

In this episode of Radiolab, Jad and Robert try to explain an inexplicable comedy act, listen to a loop that literally dies in your ear, and they learn about a loop that sent a shudder up the collective spine of mathematicians everywhere. Finally, they talk to a woman who got to watch herself think the thought that she was watching herself think the thought that she was watching herself think the thought that ... you get the point.

When a female animal is checking out her prospects, natural selection would dictate that she pay attention to how healthy, or strong, or fit he is. But when it comes to finding a mate, some animals seem to be engaged in a very different game. What if a female were looking for something else - something that has nothing to do with fitness? Something...beautiful? Today we explore a different way of looking at evolution and what it may mean for the course of science.

John Scott was the professional hockey player that every fan loved to hate. A tough guy. A brawler. A goon. But when an impish pundit named Puck Daddy called on fans to vote for Scott to play alongside the world’s greatest players in the NHL All-Star Game, Scott found himself facing off against fans, commentators, and the powers that be. Was this the realization of Scott’s childhood dreams? Or a nightmarish prank gone too far?

As legend goes, in 1562, King Philip II needed a miracle. So he commissioned one from a highly-skilled clockmaker. In this short, a king's deal with God leads to an intricate mechanical creation, and Jad heads to the Smithsonian to investigate.

When the 17-year-old crown prince of Spain, Don Carlos, fell down a set of stairs in 1562, he threw his whole country into a state of uncertainty about the future. Especially his father, King Philip II, who despite being the most powerful man in the world, was helpless in the face of his heir's terrible head wound. When none of the leading remedies of the day--bleeding, blistering, purging, or drilling--helped, the king enlisted the help of a relic...the corpse of a local holy man who had died 100 years earlier. Then, Philip II promised that if God saved his son, he'd repay him with a miracle of his own.

Elizabeth King, a professor at Virginia Commonwealth University, describes how--according to legend--Philip II held up his end of the bargain with the help of a renowned clockmaker and an intricate invention. Jad and Latif head to the Smithsonian to meet curator Carlene E. Stephens who shows them the inner workings of a nearly 450-year-old monkbot.

How do you fix a word that’s broken? A word we need when we bump into someone on the street, or break someone’s heart. In our increasingly disconnected secular world, “sorry” has been stretched and twisted, and in some cases weaponized. But it’s also one of the only ways we have to piece together a sense of shared values and beliefs. Through today's sea of sorry-not-sorries, empty apologies, and just straight up non-apologies, we wonder what it looks like to make amends.

The episode we're playing today, the third in the series, is one of the rarest stories of all: a man who publicly experiences a profound change of heart. This is a profile of one of the gods of psychotherapy, who through a reckoning with his own work (oddly enough in the pages of Playboy magazine), becomes the first domino to fall in science’s ultimate disowning of the “gay cure.”

Democracy is on the ropes. In the United States and abroad, citizens of democracies are feeling increasingly alienated, disaffected, and powerless. Some are even asking themselves a question that feels almost too dangerous to say out loud: is democracy fundamentally broken?

Today on Radiolab, just a day before the American midterm elections, we ask a different question: how do we fix it? We scrutinize one proposed tweak to the way we vote that could make politics in this country more representative, more moderate, and most shocking of all, more civil. Could this one surprisingly do-able mathematical fix really turn political campaigning from a rude bloodsport to a campfire singalong? And even if we could do that, would we want to?

It's been 80 years to the day since Orson Welles' infamous radio drama "The War of the Worlds" echoed far and wide over the airwaves. So we want to bring you back to our very first live hour, where we take a deep dive into what was one of the most controversial moments in broadcasting history. "The War of the Worlds," a radio play about Martians invading New Jersey, caused panic when it originally aired, and it's continued to fool people since--from Santiago, Chile to Buffalo, New York to a particularly disastrous evening in Quito, Ecuador.

In the final episode of our “In The No” series, we sat down with several different groups of college-age women to talk about their sexual experiences. And we found that despite colleges now being steeped in conversations about consent, there was another conversation in intimate moments that just wasn't happening. In search of a script, we dive into the details of BDSM negotiations and are left wondering if all of this talk about consent is ignoring a larger problem.

In the year since accusations of sexual assault were first brought against Harvey Weinstein, our news has been flooded with stories of sexual misconduct, indicting very visible figures in our public life. Most of these cases have involved unequivocal breaches of consent, some of which have been criminal. But what have also emerged are conversations surrounding more difficult situations to parse – ones that exist in a much grayer space. When we started our own reporting through this gray zone, we stumbled into a challenging conversation that we can’t stop thinking about. In this second episode of ‘In the No’, radio-maker Kaitlin Prest joins us for a conversation with Hanna Stotland, an educational consultant who specializes in crisis management. Her clients include students who have been expelled from school for sexual misconduct. In the aftermath, Hanna helps them reapply to school. While Hanna shares some of her more nuanced and confusing cases, we wrestle with questions of culpability, generational divides, and the utility of fear in changing our culture.

Advisory: This episode contains some graphic language and descriptions of very sensitive sexual situations, including discussions of sexual assault, consent and accountability, which may be very difficult for people to listen to.

In 2017, radio-maker Kaitlin Prest released a mini-series called "No" about her personal struggle to understand and communicate about sexual consent. That show, which dives into the experience, moment by moment, of navigating sexual intimacy, struck a chord with many of us. It's gorgeous, deeply personal, and incredibly thoughtful. And it seemed to presage a much larger conversation that is happening all around us in this moment. And so we decided to embark, with Kaitlin, on our own exploration of this topic. Over the next three episodes, we'll wander into rooms full of college students, hear from academics and activists, and sit in on classes about BDSM. But to start things off, we are going to share with you the story that started it all. Today, meet Kaitlin (if you haven't already).

Today, a challenge: bear with us.

We decided to shake things up at the show so we threw our staff a curveball, Walter Matthau-style. In two weeks time we told our producers to pitch, report, and produce stories about breaking news….or bears. What emerged was a sort of love letter for our honey-loving friends and a discovery that they embody so much more than we could have imagined: a town’s symbol for hope, a celebrity, a foe, and a clue to future ways we’ll deal with our changing environment.

Today, a fast moving, sidestepping, gene-swapping free-for-all that would’ve made Darwin’s head spin.

David Quammen tells us about a shocking way that life can evolve - infective heredity. To figure it all out we go back to the earliest versions of life, and we revisit an earlier version of Radiolab. After reckoning with a scientific icon, we find ourselves in a tangle of genes that sheds new light on peppered moths, drug-resistant bugs, and a key moment in the evolution of life when mammals went a little viral.

Horseshoe crabs are not much to look at. But beneath their unassuming catcher’s-mitt shell, they harbor a half-billion-year-old secret: a superpower that helped them outlive the dinosaurs and survive all the Earth’s mass extinctions. And what is that secret superpower? Their blood. Their baby blue blood. And it’s so miraculous that for decades, it hasn’t just been saving their butts, it’s been saving ours too.

But that all might be about to change.

Follow us as we follow these ancient critters - from a raunchy beach orgy to a marine blood drive to the most secluded waterslide - and learn a thing or two from them about how much we depend on nature and how much it depends on us.

Back in 2008 Facebook began writing a document. It was a constitution of sorts, laying out what could and what couldn’t be posted on the site. Back then, the rules were simple, outlawing nudity and gore. Today, they’re anything but.

How do you define hate speech? Where’s the line between a joke and an attack? How much butt is too much butt? Facebook has answered these questions. And from these answers they’ve written a rulebook that all 2.2 billion of us are expected to follow. Today, we explore that rulebook. We dive into its details and untangle its logic. All the while wondering what does this mean for the future of free speech?

With all of the black-and-white moralizing in our world today, we decided to bring back an old show about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us.

Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why?

When Dana Zzyym applied for their first passport back in 2014, they were handed a pretty straightforward application. Name, place of birth, photo ID -- the usual. But one question on the application stopped Dana in their tracks: male or female? Dana, technically, wasn’t either.

In this episode, we follow the story of Dana Zzyym, Navy veteran and activist, which starts long before they scribble the word "intersex” on their passport application. Along the way, we see what happens when our inner biological realities bump into the outside world, and the power of words to shape us.

This episode is a companion piece to Gonads, Episode 4, Dutee.

In 2014, India’s Dutee Chand was a rising female track and field star, crushing national records. But then, that summer, something unexpected happened: she failed a gender test. And was banned from the sport. Before she knew it, Dutee was thrown into the middle of a controversy that started long before her, and continues on today: how to separate males and females in sport.

This story is a companion piece to Gonads, Episode 5, Dana.

At 28 years old, Annie Dauer was living a full life. She had a job she loved as a highschool PE teacher, a big family who lived nearby, and a serious boyfriend. Then, cancer struck. Annie would come to find out she had Stage 4 non-Hodgkin's lymphoma. It was so aggressive, there was a real chance she might die. Her oncologists wanted her to start treatment immediately. Like, end-of-the-week immediately. But before Annie started treatment, she walked out of the doctor’s office and crossed the street to see a fertility doctor doing an experimental procedure that sounded like science fiction: ovary freezing.

We originally posted this episode in 2015, and it inspired producer Molly Webster to take a deep dive into the wild and mysterious world of human reproduction. Starting next week, she’ll be taking over the Radiolab podcast feed for a month to present a series of mind-bending stories that make us rethink the ways we make more of us.

You know the drill - all it takes is one sperm, one egg, and blammo - you got yourself a baby. Right? Well, in this episode, conception takes on a new form - it’s the sperm and the egg, plus: two wombs, four countries, and money. Lots of money.

At first, this is the story of an Israeli couple, two guys, who go to another continent to get themselves a baby - three, in fact - by hiring surrogates to carry the children for them. As we follow them on their journey, an earth shaking revelation shifts our focus from them, to the surrogate mothers. Unfolding in real time, as countries around the world consider bans on surrogacy, this episode looks at a relationship that manages to feel deeply affecting, and deeply uncomfortable, all at the same time.

Birthstory is a collaboration with the brilliant radio show and podcast Israel Story, created to tell stories for, and about, Israel. Go check ‘em out!

When reporter Brenna Farrell was a new mom, her son gave her and her husband a scare -- prompting them to call Poison Control. For Brenna, the experience was so odd, and oddly comforting, that she decided to dive into the birth story of this invisible network of poison experts, and try to understand the evolving relationship we humans have with our poisonous planet. As we learn about how poison control has changed over the years, we end up wondering what a place devoted to data and human connection can tell us about ourselves in this cultural moment of anxiety and information-overload.

This week, we're throwing it back to an old favorite: a story about obsession, creativity, and a strange symmetry between a biologist and a composer that revolves around one famously repetitive piece of music.

Anne Adams was a brilliant biologist. But when her son Alex was in a bad car accident, she decided to stay home to help him recover. And then, rather suddenly, she decided to quit science altogether and become a full-time artist. After that, her husband Robert Adams tells us, she just painted and painted and painted. First houses and buildings, then a series of paintings involving strawberries, and then ... "Bolero."

At some point, Anne became obsessed with Maurice Ravel's famous composition and decided to put an elaborate visual rendition of the song to canvas. She called it "Unraveling Bolero." But at the time, she had no idea that both she and Ravel would themselves unravel shortly after their experiences with this odd piece of music. Arbie Orenstein tells us what happened to Ravel after he wrote "Bolero," and neurologist Bruce Miller helps us understand how, for both Anne and Ravel, "Bolero" might have been the first symptom of a deadly disease.

Seven years ago chatbots - those robotic texting machines - were a mere curiosity. They were noticeably robotic and at their most malicious seemed only capable of scamming men looking for love online. Today, the chatbot landscape is wildly different. From election interference to spreading hate, chatbots have become online weapons.

And so, we decided to reinvestigate the role these robotic bits of code play in our lives and the effects they’re having on us. We begin with a little theater. In our live show “Robert or Robot?” Jad and Robert test 100 people to see if they can spot a bot. We then take a brief detour to revisit the humanity of the Furby, and finish in a virtual house where the line between technology and humanity becomes blurrier than ever before.

Note from the Managing Editor:

In the original version of our “More or Less Human” podcast, our introduction of neuroscientist Mavi Sanchez-Vives began with mention of her husband, Mel Slater. We’ve edited that introduction because it was a mistake to introduce her first as someone’s wife. Dr. Sanchez-Vives is an exceptional scientist and we’re sorry that the original introduction distracted from or diminished her work.

On a personal note, I failed to take due note of this while editing the piece, and in doing so, I flubbed what’s known as the Finkbeiner Test (all the more embarrassing given that Ann Finkebeiner is a mentor and one of my favorite science journalists). In addition to being a mistake, this is also a reminder to all of us at Radiolab that we need to be more aware of our blind spots. We should’ve done better, and we will do better.

Astronauts at the International Space Station can make one request to talk to an earthling of their choice. For some reason, Astronaut Mark Vande Hei chose us. A couple weeks ago, we were able to video chat with Mark and peer over his shoulder through the Cupola, an observatory room in the ISS. Traveling at 17,000 miles an hour, we zoomed from the Rockies to the East Coast in minutes. And from where Mark sits, the total darkness of space isn’t very far away.

Talking to Mark brought us back to 2012, when we spoke to another astronaut, Dave Wolf. When we were putting together our live show In the Dark, Jad and Robert called up Dave Wolf to ask him if he had any stories about darkness. And boy, did he. Dave told us two stories that became the finale of our show.

Back in late 1997, Dave Wolf was on his first spacewalk, to perform work on the Mir. Dave wasn't alone -- with him was veteran Russian cosmonaut Anatoly Solovyev.

Out in blackness of space, the contrast between light and dark is almost unimaginably extreme -- every 45 minutes, you plunge between absolute darkness on the night-side of Earth, and blazing light as the sun screams into view. Dave and Anatoly were tethered to the spacecraft, traveling 5 miles per second. That's 16 times faster than we travel on Earth's surface as it rotates -- so as they orbited, they experienced 16 nights and 16 days for every Earth day.

Dave's description of his first spacewalk was all we could've asked for, and more. But what happened next ... well, it's just one of those stories that you always hope an astronaut will tell. Dave and Anatoly were ready to call it a job and head back into the Mir when something went wrong with the airlock. They couldn't get it to re-pressurize. In other words, they were locked out. After hours of trying to fix the airlock, they were running out of the resources that kept them alive in their space suits and facing a grisly death. So, they unhooked their tethers, and tried one last desperate move.

In the end, they made it through, and Dave went on to perform dozens more spacewalks in the years to come, but he never again experienced anything like those harrowing minutes trying to improvise his way back into the Mir.

After that terrifying tale, Dave told us about another moment he and Anatoly shared, floating high above Earth, staring out into the universe ... a moment so beautiful, and peaceful, we decided to use the audience recreate it, as best we could, for the final act of our live show.

Border Trilogy

While scouring the Sonoran Desert for objects left behind by migrants crossing into the United States, anthropologist Jason De León happened upon something he didn't expect to get left behind: a human arm, stripped of flesh.

This macabre discovery sent him reeling, needing to know what exactly happened to the body, and how many migrants die that way in the wilderness. In researching border-crosser deaths in the Arizona desert, he noticed something surprising. Sometime in the late-1990s, the number of migrant deaths shot up dramatically and have stayed high since. Jason traced this increase to a Border Patrol policy still in effect, called “Prevention Through Deterrence.”

Over three episodes, Radiolab will investigate this policy, its surprising origins, and the people whose lives were changed forever because of it.

Part 3: What Remains

The third episode in our Border Trilogy follows anthropologist Jason De León after he makes a grisly discovery in Arivaca, Arizona. In the middle of carrying out his pig experiments with his students, Jason finds the body of a 30-year-old female migrant. With the help of the medical examiner and some local humanitarian groups, Jason discovers her identity. Her name was Maricela. Jason then connects with her family, including her brother-in-law, who survived his own harrowing journey through Central America and the Arizona desert.

With the human cost of Prevention Through Deterrence weighing on our minds, we try to parse what drives migrants like Maricela to cross through such deadly terrain, and what, if anything, could deter them.

Part 2: Hold the Line

After the showdown in court with Bowie High School, Border Patrol brings in a fresh face to head its dysfunctional El Paso Sector: Silvestre Reyes. The first Mexican-American to ever hold the position, Reyes knows something needs to change and has an idea how to do it. One Saturday night at midnight, with the element of surprise on his side, Reyes unveils ... Operation Blockade. It wins widespread support for the Border Patrol in El Paso, but sparks major protests across the Rio Grande. Soon after, he gets a phone call that catapults his little experiment onto the national stage, where it works so well that it diverts migrant crossing patterns along the entire U.S.-Mexico Border.

Years later, in the Arizona desert, anthropologist Jason de León realizes that in order to accurately gauge how many migrants die crossing the desert, he must first understand how human bodies decompose in such an extreme environment. He sets up a macabre experiment, and what he finds is more drastic than anything he could have expected.

We also omitted a detail about the 1997 GAO report that we quote, namely that it predicted that as deaths in the mountains and deserts might rise, deaths in other areas might also fall. The audio has been adjusted accordingly.

Part 1: Hole in the Fence:

We begin one afternoon in May 1992, when a student named Albert stumbled in late for history class at Bowie High School in El Paso, Texas. His excuse: Border Patrol. Soon more stories of students getting stopped and harassed by Border Patrol started pouring in. So begins the unlikely story of how a handful of Mexican-American high schoolers in one of the poorest neighborhoods in the country stood up to what is today the country’s largest federal law enforcement agency. They had no way of knowing at the time, but what would follow was a chain of events that would drastically change the US-Mexico border.

One of our most popular episodes of all time was our Colors episode, where we introduced you to a sea creature that could see a rainbow far beyond what humans can experience.

Peacock mantis shrimps are as extraordinary as they are strange and boast what may well be the most complicated visual system in the world. They each have 16 photoreceptors compared to our measly three. But recently researchers in Australia put the mantis shrimps’ eyes to the test only to discover that sure, they can SEE lots of colors, but that doesn't mean they can tell them apart.

In fact, when two colors are close together - like yellow and yellow-y green - they can’t seem to tell them apart at all.

MORE ON COLORS: There was a time -- between the flickery black-and-white films of yore and the hi-def color-corrected movies we watch today -- when color was in flux. Check out this blog post on how colors made it to the big screen from our director of research, Latif Nasser.

The shooting in Parkland, Florida on February 14, 2018, reignited an increasingly familiar debate about guns in this country. Today, we’re re-releasing a More Perfect episode that aired just after the Las Vegas shooting last year that attempts to make sense of our country’s fraught relationship with the Second Amendment.

For nearly 200 years of our nation’s history, the Second Amendment was an all-but-forgotten rule about the importance of militias. But in the 1960s and 70s, a movement emerged — led by Black Panthers and a recently-repositioned NRA — that insisted owning a firearm was the right of each and every American. So began a constitutional debate that only the Supreme Court could solve. That didn’t happen until 2008, when a Washington, D.C. security guard named Dick Heller made a compelling case.

We don’t do breaking news. But when Robert Mueller released his indictment a few days ago, alleging that 13 Russian nationals colluded to disrupt the 2016 elections, we had a lot of questions. Who are these Russian individuals sowing discord? And who are these Americans that were manipulated?? Join us as we follow a trail of likes and tweets that takes us from a Troll Factory to a Cheesecake Factory.

Do you really need a brain to sense the world around you? To remember? Or even learn? Well, it depends on who you ask. Jad and Robert, they are split on this one. Today, Robert drags Jad along on a parade for the surprising feats of brainless plants. Along with a home-inspection duo, a science writer, and some enterprising scientists at Princeton University, we dig into the work of evolutionary ecologist Monica Gagliano, who turns our brain-centered worldview on its head through a series of clever experiments that show plants doing things we never would've imagined. Can Robert get Jad to join the march?

In anticipation of Super Bowl LII (Go Eagles), we're revisiting an old episode about the surprising history of how the game came to be. It's the end of the 19th century -- the Civil War is over, and the frontier is dead. And young college men are anxious. What great struggle will test their character? Then along comes a new craze: football. A brutally violent game where young men can show a stadium full of fans just what they're made of. Harvard, Yale, Princeton, Penn -- the sons of the most powerful men in the country are literally knocking themselves out to win these gladiatorial battles. And then the most American team of all, with the most to prove, gets in the game and owns it. The Carlisle Indian School, formed in 1879 to assimilate the children and grandchildren of the men who fought the final Plains Wars against the fathers and grandfathers of the Ivy Leaguers, starts challenging the best teams in the country. On the football field, Carlisle had a chance for a fair fight with high stakes -- a chance to earn respect, a chance to be winners, and a chance to go forward in a changing world that was destroying theirs.

An unassuming string of 16 words tucked into the Constitution grants Congress extensive power to make laws that impact the entire nation. The Commerce Clause has allowed Congress to intervene in all kinds of situations — from penalizing one man for growing too much wheat on his farm, to enforcing the end of racial segregation nationwide. That is, if the federal government can make an economic case for it. This seemingly all-powerful tool has the potential to unite the 50 states into one nation and protect the civil liberties of all. But it also challenges us to consider: when we make everything about money, what does it cost us?

How do you pay proper tribute to a legend that many people haven’t heard of?

We began asking ourselves this question last week when the visionary radio producer Joe Frank passed away, after a long struggle with colon cancer. Joe Frank was the radio producer’s radio producer. He told stories that were thrillingly weird, deeply mischievous (and sometimes head-spinningly confusing!). He had a big impact on us at Radiolab. For Jad, his Joe Frank moment happened in 2002, while sitting at a mixing console in an AM radio studio waiting to read the weather. Joe Frank's Peabody Award-winning series "Rent-A-Family” came on the air.

Time stood still.

We’ve since learned that many of our peers have had similar Joe Frank moments.

In this episode, we commemorate one of the greats with Brooke Gladstone from On the Media and Ira Glass from This American Life.

What are people thinking when they risk their lives for someone else? Are they making complicated calculations of risk or diving in without a second thought? Is heroism an act of sympathy or empathy?

A few years ago, we spoke with Walter F. Rutkowski about how the Carnegie Hero Fund selects its heroes, an honor the fund bestows upon ordinary people who have done extraordinary acts.

When some of these heroes were asked what they were thinking when they leapt into action, they replied: they didn’t think about it, they just went in.

Neuroscientist Robert Sapolsky says there is a certain kind of empathy that leads to action. But feeling the pain of another person deeply is not necessarily what makes a hero.

Here at the show, we get a lot of questions. Like, A LOT of questions. Tiny questions, big questions, short questions, long questions. Weird questions. Poop questions. We get them all.

And over the years, as more and more of these questions arrived in our inbox, what happened was, guiltily, we put them off to the side, in a bucket of sorts, where they just sat around, unanswered. But now, we’re dumping the bucket out.

Today, our producers pick up a few of the questions that spilled out of that bucket, and venture out into the great unknown to find answers to some of life's greatest mysteries: coincidences; miracles; life; death; fate; will; and, of course, poop.

When we started reporting a fantastic, surreal story about one very cold night, more than 70 years ago, in northern Russia, we had no idea we'd end up thinking about cosmology. Or dropping toy horses in test tubes of water. Or talking about bacteria. Or arguing, for a year. Walter Murch (aka, the Godfather of The Godfather), joined by a team of scientists, leads us on what felt like the magical mystery tour of super cool science.

Back in 1995, Claude Steele published a study that showed that negative stereotypes could have a detrimental effect on students' academic performance. But the big surprise was that he could make that effect disappear with just a few simple changes in language. We were completely enamoured with this research when we first heard about it, but in the current roil of replications and self-examination in the field of social psychology, we have to wonder whether we can still cling to the hopes of our earlier selves, or if we might have to grow up just a little bit.

You never know what might happen when you sign up to donate bone marrow. You might save a life… or you might be magically transported across a cultural chasm and find yourself starring in a modern adaptation of the greatest story ever told.

One day, without thinking much of it, Jennell Jenney swabbed her cheek and signed up to be a donor. Across the country, Jim Munroe desperately needed a miracle, a one-in-eight-million connection that would save him. It proved to be a match made in marrow, a bit of magic in the world that hadn’t been there before. But when Jennell and Jim had a heart-to-heart in his suburban Dallas backyard, they realized they had contradictory ideas about where that magic came from. Today, an allegory for how to walk through the world in a way that lets you be deeply different, but totally together.

There’s nothing quite like the sound of someone thinking out loud, struggling to find words and ideas to match what’s in their head. Today, we are allowed to dip into the unfiltered thoughts of Oliver Sacks, one of our heroes, in the last months of his life.

Oliver died in 2015, but before he passed he and his partner Bill Hayes, in an effort to preserve some of Oliver’s thoughts on his work and his life, bought a little tape recorder. Over a year and half after Oliver’s death, Bill dug up the recorder and turned it on. Through snippets of conversation with Bill, and in moments Oliver recorded whispering to himself as he wrote, we get a peek inside the head, and the life, of one of the greatest science essayists of all time.

The passages read in this piece all come from Oliver’s recently released, posthumous book, The River of Consciousness.

Today, while the divisions between different groups in this country feel more and more insurmountable, we zero in on a particular neighborhood to see if one man can draw people together in a potentially history-making election.

Khader El-Yateem is a Palestinian American running for office in Bay Ridge, Brooklyn, one of the most divided, and most conservative neighborhoods in New York City. To win, he'll need to convince a wildly diverse population that he can speak for all of them, and he'll need to pull one particular group of people, Arab American Muslims, out of the shadows and into the political process. And to make things just a bit more interesting, El-Yateem is a Lutheran minister.

What happens when the Supreme Court, the highest court in the land, seems to get it wrong? Korematsu v. United States is a case that’s been widely denounced and discredited, but it still remains on the books. This is the case that upheld President Franklin Roosevelt’s internment of American citizens during World War II based solely on their Japanese heritage, for the sake of national security. In this episode, we follow Fred Korematsu’s path to the Supreme Court, and we ask the question: if you can’t get justice in the Supreme Court, can you find it someplace else?

The key voices:

Fred Korematsu, plaintiff in Korematsu v. United States who resisted evacuation orders during World War II. Karen Korematsu, Fred’s daughter, Founder & Executive Director of Fred T.

Most of us would sacrifice one person to save five. It’s a pretty straightforward bit of moral math. But if we have to actually kill that person ourselves, the math gets fuzzy.

That’s the lesson of the classic Trolley Problem, a moral puzzle that fried our brains in an episode we did about 11 years ago. Luckily, the Trolley Problem has always been little more than a thought experiment, mostly confined to conversations at a certain kind of cocktail party. That is until now. New technologies are forcing that moral quandry out of our philosophy departments and onto our streets. So today we revisit the Trolley Problem and wonder how a two-ton hunk of speeding metal will make moral calculations about life and death that we can’t even figure out ourselves.

One morning, Oliver Sipple went out for a walk. A couple hours later, to his own surprise, he saved the life of the President of the United States. But in the days that followed, Sipple’s split-second act of heroism turned into a rationale for making his personal life into political opportunity. What happens next makes us wonder what a moment, or a movement, or a whole society can demand of one person. And how much is too much?

Through newly unearthed archival tape, we hear Sipple himself grapple with some of the most vexing topics of his day and ours - privacy, identity, the freedom of the press - not to mention the bonds of family and friendship.

This week, we are presenting a story from NPR foreign correspondent Gregory Warner and his new globe-trotting podcast Rough Translation.

Mohammed was having the best six months of his life - working a job he loved, making mixtapes for his sweetheart - when the communist Somali regime perp-walked him out of his own home, and sentenced him to a lifetime of solitary confinement. With only concrete walls and cockroaches to keep him company, Mohammed felt miserable, alone, despondent. But then one day, eight months into his sentence, he heard a whisper, a whisper that would open up a portal to - of all places and times - 19th century Russia, and that would teach him how to live and love again.

15 years ago the very first episode of Radiolab, fittingly called "Firsts," hit the airwaves. It was a 3-hour long collection of documentaries and musings produced by a solitary sleep-deprived producer named Jad Abumrad. Things have changed a bit since then. Today, with help from our long time Executive Producer Ellen Horne, we celebrate our 15th birthday by surprising Jad and Robert in the studio and forcing them to look back on a time when “Radiolab” was just that: a lab for experimenting with radio.Support Radiolab by becoming a member today at Radiolab.org/donate.

Back when Robert was kid, he had a chance encounter with then President John F. Kennedy. The interaction began with a hello and ended with a handshake. And like many of us who have touched greatness, 14 year old Robert was left wondering if maybe some of Kennedy would stay with him. Now, 50 years later, Robert still finds himself pondering that encounter and question. And so with the help of brand new science and Neil Degrasse Tyson, he sets out to satisfy this curiosity once and for all.

*** As of Wednesday, May 3rd, 2017 we've run out of kits. Thanks so much to uBiome for generously donating over 13,000 free kits, and thanks to everyone for participating. ***

Who is uBiome?

uBiome is a California-based biotech company started in 2012 that sequences the DNA of the microbes that live on and in you.

Do I have to pay for my results?

No, as long as you use the code for Radiolab/Only Human listeners, the sequencing results are free! uBiome otherwise charges $89 to have a skin sample analyzed.

Am I going to find out if I’m sick?

This uBiome information isn’t for diagnosing any health condition.

How long will it take to get my results?

It can take from 3-6 weeks from when uBiome receives your sample to sequence, process and compile the material. So please send those samples back to the uBiome labs soon, so we can report back to you about the Radiolab/Only Human group.

What is uBiome going to do with my microbiome info?

uBiome scientists are going to share aggregate level analysis with Radiolab and Only Human so we can give general results about our group’s skin microbiome. Aside from that, what uBiome does with your results generally depends on whether you choose to be included in research or share your information. uBiome is HIPAA-compliant, and their practices are reviewed by an independent committee for ethical research (an IRB). For more information, see uBiome’s summary of its privacy practices (just 6 pages in regular-sized font).

Will I be able to get my raw data?

Yes! Once your results are in, you’ll be able to download it as a CSV, JSON or FASTQ file.

Will they take my DNA and clone me?

If by “me”, you mean the human you, then no, uBiome isn’t going to clone, let alone even sequence human DNA.

President Richard Nixon once boasted that at any moment he could pick up a telephone and - in 20 minutes - kill 60 million people. Such is the power of the US President over the nation’s nuclear arsenal. But what if you were the military officer on the receiving end of that phone call? Could you refuse the order?

This episode, we profile one Air Force Major who asked that question back in the 1970s and learn how the very act of asking it was so dangerous it derailed his career. We also pick up the question ourselves and pose it to veterans both high and low on the nuclear chain of command. Their responses reveal once and for all whether there are any legal checks and balances between us and a phone call for Armageddon.

A couple years ago, Ben Montgomery, reporter at the Tampa Bay Times, started emailing every police station in Florida.

He was asking for any documents created - from 2009 to 2014 - when an officer discharged his weapon in the line of duty. He ended up with a six foot tall stack of reports, pictures, and press clippings cataloging the death or injury of 828 people by Florida police.

In part 2 of Shots Fired, Jad and Robert talk to Ben about how communication breakdowns too often lead to violence and our reporter Matt Kielty sits with one man who found himself at the center of a police visit gone horribly wrong.

Correction: An earlier version of this story incorrectly stated that in reporter Ben Montgomery's six years of Florida data there were, on average, 130 people shot and killed each year. Police offers did indeed shoot 130 people per year, on average, but only half of those shootings were fatal. The audio has been adjusted to reflect this fact.

It's been almost two years since we learned about CRISPR, a ninja-assassin-meets-DNA-editing-tool that has been billed as one of the most powerful, and potentially controversial, technologies ever discovered by scientists. In this episode, we catch up on what's been happening (it's a lot), and learn about CRISPR's potential to not only change human evolution, but every organism on the entire planet.

Out drinking with a few biologists, Jad finds out about something called CRISPR. No, it’s not a robot or the latest dating app, it’s a method for genetic manipulation that is rewriting the way we change DNA. Scientists say they’ll someday be able to use CRISPR to fight cancer and maybe even bring animals back from the dead. Or, pretty much do whatever you want. Jad and Robert delve into how CRISPR does what it does, and consider whether we should be worried about a future full of flying pigs, or the simple fact that scientists have now used CRISPR to tweak the genes of human embryos.

We thought we knew the story of Bernie Madoff. How he masterminded the biggest Ponzi scheme in history, leaving behind scores of distraught investors and a $65 billion black hole.

But we had never heard the story from Madoff himself.

This week, reporter Steve Fishman and former Radiolabber Ellen Horne visit our studio to play us snippets from their extraordinary Audible series Ponzi Supernova, which features exclusive footage of the man who bamboozled the world. After years of investigative reporting – including interviews with dozens of FBI and SEC agents, investors, traders, and attorneys – the pair scrutinize Madoff’s account to understand exactly why he did it, how he managed to pull it off, and how culpable he actually was. Was he a puppetmaster or a puppet? And if the latter, who else is to blame for the biggest financial fraud in history?

Back in 1911, a box with a dead raccoon in it showed up in Washington D.C., at the office of Gerrit S. Miller. After pulling it out and inspecting it, he realized this raccoon was from the Caribbean islands of Guadeloupe, and unlike anything he’d ever seen before. He christened it Procyon minor and in doing so changed the history of Guadeloupe forever.

In a 5-part series called "Busted: America’s Poverty Myths,” On the Media picked apart numerous oft-repeated narratives about what it's like to be poor in America. From Ben Franklin to a brutal eviction, Brooke gives us just a little taste of what she learned and shares a couple stories of the struggle to get ahead, or even just get by.

No matter what sport you play, the object of the game is to win. And that’s hard enough to do. But we found a match where four top athletes had to do the opposite in one of the most high profile matches of their careers. Thanks to a quirk in the tournament rules, their best shot at winning was … to lose.

Straight from MIT’s research files, this image shows microglia who have gotten light stimulation therapy (one can only hope in the flicker room).

Come election season, it's easy to get cynical. Why cast a ballot if your single measly vote can't possibly change anything?

In our first-ever election special, we set off to find a single vote that made a difference. We venture from the biggest election on the planet - where polling officials must brave a lion-inhabited forest to collect the vote of an ascetic temple priest - to the smallest election on the planet - where there are no polling officials, only kitty cats wearing nametags. Along the way, we meet a too-trusting advice columnist, a Texan Emperor, and a passive-aggressive mom who helped change American democracy forever.

Last May, two research groups announced a breakthrough: they each grew human embryos, in the lab, longer than ever before. In doing so, they witnessed a period of human development no one had ever seen. But in the process, they crashed up against something called the '14-day rule,' a guideline set over 30 years ago that dictates what we do, and possibly how we feel, about human embryos in the lab.

On this episode, join producer Molly Webster as she peers down at our very own origins, and wonders: what do we do now?

Producer's note about the image:

Check out the super cool picture that's running with this piece. Scientist Gist Croft sent it to me a couple of weeks after my visit to the Rockefeller lab: it’s an image of the very embryo I looked at under the microscope - a twelve-day old human embryo - but with all the detail highlighted using fluorescent dye. (When I looked in person, we were using a light microscope that showed everything in black and white, with not nearly that precision.) The neon green bits are what's called the epiblast, the clump of cells from which the entire human body develops. See how it looks like it's pulling apart in to two? The scientists don’t know for sure, but they think this embryo might have been on it's way to becoming TWO embryos. Twinning! In action!

An update on Ross McNutt and his superpower — he can zoom in on everyday life, then rewind and fast-forward to solve crimes in a shutter-flash. But should he?

In 2004, when casualties in Iraq were rising due to roadside bombs, Ross McNutt and his team came up with an idea. With a small plane and a 44 mega-pixel camera, they figured out how to watch an entire city all at once, all day long. Whenever a bomb detonated, they could zoom onto that spot and then, because this eye in the sky had been there all along, they could scroll back in time and see - literally see - who planted it. After the war, Ross McNutt retired from the Air Force, and brought this technology back home with him. Manoush Zomorodi and Alex Goldmark from the podcast “Note to Self” give us the lowdown on Ross’s unique brand of persistent surveillance, from Juarez, Mexico to Dayton, Ohio. Then, once we realize what we can do, we wonder whether we should.

In today’s episode, we meet a young woman from Texas, born and raised, who can’t prove that she exists.

Alecia Faith Pennington was born at home, homeschooled, and never visited a dentist or a hospital. By both chance and design she is completely invisible in the eyes of the state. We follow Faith as she struggles to free herself from one restrictive world only to find that she is trapped in another. In her journey to prove her American citizenship she attempts to answer the age-old question: who am I?

Correction: An earlier version of this episode's web copy incorrectly stated that Faith Pennington was born on a farm. Pennington was born at home in Houston, TX, then she and her family moved to a farm in Kerrville, TX, where she was raised.

When people are dying and you can only save some, how do you choose? Maybe you save the youngest. Or the sickest. Maybe you even just put all the names in a hat and pick at random. Would your answer change if a sick person was standing right in front of you?

In this episode, we follow New York Times reporter Sheri Fink as she searches for the answer. In a warzone, a hurricane, a church basement, and an earthquake, the question remains the same. What happens, what should happen, when humans are forced to play god?

A forest can feel like a place of great stillness and quiet. But if you dig a little deeper, there’s a hidden world beneath your feet as busy and complicated as a city at rush hour.

In this story, a dog introduces us to a strange creature that burrows beneath forests, building an underground network where deals are made and lives are saved (and lost) in a complex web of friendships, rivalries, and business relations. It’s a network that scientists are only just beginning to untangle and map, and it’s not only turning our understanding of forests upside down, it’s leading some researchers to rethink what it means to be intelligent.

Correction: An earlier version of this story misidentified naturalist David Attenborough as his late brother, actor Richard Attenborough. In addition, it dated the earliest scientific studies of fungi to the late 19th century, whereas naturalists have studied fungi since the 17th century. Lastly, we mistakenly stated that the oxygen that a plant respires comes from CO2, when in reality it comes from water. The audio has been adjusted to correct these facts.

David Weinberg was stuck. He had been kicked out of college, was cleaning toilets by day, delivering pizzas by night and spending his weekends in jail. Then one night he heard a story on the radio and got it in his head that maybe he too could make a great radio story. He’d cast himself as the main character in a great documentary and he’d travel and live and steer his way out of his rut.

So he bought a recorder and began to secretly record every last meaningful and mundane minute of his life and he found his great idea transformed into a troubling obsession. The very thing that gave him hope and purpose was also distancing him from those he loved the most. What if he’d created an archive of his life that had become his life?

On this episode, we visit Edward Blum, a 64-year-old “legal entrepreneur” and former stockbroker who has become something of a Supreme Court matchmaker. He’s had remarkable success, with 6 cases heard before the Supreme Court, including that of Abigail Fisher. We also head to Houston, Texas, where in 1998, an unusual 911 call led to one of the most important LGBT rights decisions in the Supreme Court’s history.

The question of how much power the Supreme Court should possess has divided justices over time. But the issue was perhaps never more hotly debated than in Baker v. Carr. On this episode of More Perfect, we talk about the case that pushed one Supreme Court justice to a nervous breakdown, brought a boiling feud to a head, put one justice in the hospital, and changed the course of the Supreme Court – and the nation – forever.

In 1973, a massive manhunt in New York's Adirondack Mountains ended when police captured a man named Robert Garrow. And that’s when this story really gets started. This episode we consider a string of barbaric crimes by a hated man, and the attorney who, when called to defend him, also wound up defending a core principle of our legal system. When Frank Armani learned his client’s most gruesome secrets, he made a morally startling decision that stunned the world and goes to the heart of what it means to be a defense attorney - how far should lawyers go to provide the best defense to the worst people?

NOTE: This episode contains graphic descriptions of sexual assault and violence.

How does an elite group of nine people shape everything from marriage and money, to safety and sex for an entire nation? From the producers of Radiolab, More Perfect dives into the rarefied world of the Supreme Court to explain how cases deliberated inside hallowed halls affect lives far away from the bench.

Today's story is a mystery, shockingly hot, and vanishingly tiny.

It starts with a sound, rising like a mist from the marsh, around a dock in South Carolina. But where it goes next - from submarines to superheroes (and yes, Keanu Reeves!); from the surface of the sun to the middle of the brain - is far from expected. Producer Molly Webster brings her family along for the ride. Enjoy the adventure, before it...implodes.

At the 1998 Olympics in Nagano, Japan, one athlete pulled a move that, so far as we know, no one else had ever done in all of human history.

Surya Bonaly was not your typical figure skater. She was black. She was athletic. And she didn’t seem to care about artistry. Her performances – punctuated by triple-triple jumps and other power moves – thrilled audiences around the world. Yet, commentators claimed she couldn’t skate, and judges never gave her the high marks she felt she deserved. But Surya didn’t accept that criticism. Unlike her competitors – ice princesses who hid behind demure smiles – Surya made her feelings known. And, at her final Olympic performance, she attempted one jump that flew in the face of the establishment, and marked her for life as a rebel.

This week, we lace up our skates and tell a story about loving a sport that doesn’t love you back, and being judged in front of the world according to rules you don’t understand.

An update on Juniper French, a tiny baby, born at 23 Weeks and 6 days -- roughly halfway to full term. And a whole universe of medical and moral questions.

Technology has had a profound effect on how we get pregnant, give birth, and think about life and death. The decision to become parents was not an easy one for Kelley and Tom. Even after they sorted out their relationship issues and hopes for the future, getting pregnant wasn't easy. But, thanks to a lot of technology, they found a way to a baby. Then, about halfway through the pregnancy, the trouble began. Neonatal nurse practitioner Diane Loisel describes helping Kelley and Tom make the most important decision of their lives. And Nita Farahany helps Jad and Robert understand the significance of viability, and how technology has influenced its meaning...making a difficult idea even harder to pin down.

Kelley and Tom had hoped that meeting their daughter would be the happiest moment of their life. But when she came early -- at just 23 weeks and 6 days, that moment was full of terror and an impossibly difficult decision. And when the time came to face it, Tom and Kelley turned to their baby for help. Seeing their daughter for the first time, they looked for her to "declare herself." That's a phrase that comes up again and again to help guide decisions in Neonatal Intensive Care Units. But parents and medical professionals have very different ideas about what the phrase really means. Nurse Tracy Hullet and Neonatologist Keith Barrington describe the difficulty of interpreting the fuzzy boundary between a baby's strength of will, and simple physiology. Meanwhile Kelley and Tom are left to wonder, and wait.

The Neonatal Intensive Care Unit, or NICU, is a land of emotional and medical limbo. Kelley, Tom, and their daughter Juniper got stranded in this limbo for months, fighting to survive, and finally get to the next chapter of their lives. Their doctor, Fauzia Shakeel, describes the moment when Juniper's life hung in the balance, and Keith Barrington helps us understand how our newest technologies open the door not only to hope, but also to a pain that we, as humans, have kept hidden for most of our history.

And finally, Kelley, Tom, Nita Farahany and Juniper herself, nearly 5 years old, give us an update on her life and what has happened since our story originally aired.

Unclasp your briefcase. It’s time for a showdown. In competitive debate future presidents, supreme court justices, and titans of industry pummel each other with logic and rhetoric. But a couple years ago Ryan Wash, a queer, Black, first-generation college student from Kansas City, Missouri joined the debate team at Emporia State University. When he started going up against fast-talking, well-funded, “name-brand” teams, it was clear he wasn’t in Kansas anymore. So Ryan became the vanguard of a movement that made everything about debate debatable. In the end, he made himself a home in a strange and hostile land. Whether he was able to change what counts as rigorous academic argument … well, that’s still up for debate.

In the U.S., paparazzi are pretty much synonymous with invasion of privacy. But today we travel to a place where the prying press create something more like a prison break.

K-pop is a global juggernaut - with billions in sales and millions of fans hanging on every note, watching K-pop idols synchronize and strut. And that fame rests on a fantasy, K-pop stars have to be chaste and pure, but also … available. Until recently, Korean music agencies and K-pop fans held their pop stars to a strict set of rules designed to keep that fantasy alive. That is, until Dispatch showed up.

Taking a cue from American and British paparazzi, a group of South Korean reporters started hiding in their cars and snapping photos of stars on their secret dates. The first-ever paparazzi photos turned the world of K-pop upside down and introduced sort of a puzzle … how much do you want to know about the people you idolize, and when is enough enough?

Roosevelt, Kennedy, Eisenhower … they all got a pass. But today we peer back at the moment when poking into the private lives of political figures became standard practice.

In 1987, Gary Hart was a young charismatic Democrat, poised to win his party’s nomination and possibly the presidency. Many of us know the story of what happened next, and even if you don’t, it’s a familiar tale. But at the time, politicians and political reporters found themselves in uncharted territory. With help from author Matt Bai, we look at how the events of that May shaped the way we cover politics, and expanded our sense of what's appropriate when it comes to judging a candidate.

Ryan and Amy Green were facing the unfaceable: their youngest son, Joel was diagnosed with terminal cancer after his first birthday. Producer Sruthi Pinnamaneni tells the story of how Ryan and Amy stumble onto an unlikely way of processing their experience fighting alongside Joel: they decide to turn it into a video game. In the end, they find themselves facing what might be, for a game designer or a parent, the hardest design problem ever.

Correction: In the original audio we stated that the survival rate of childhood AT/RT cancer is 50% over five years. But studies suggest the survival rate is 50% over two years. The audio has been updated to reflect this change.

This episode we take a sober look at the throbbing, aching, craving desire states that return people (again and again) to the object of their addiction … and the pills that just might set them free.

Reporter Amy O’Leary was fed up with her ex-boyfriend’s hard-drinking, when she discovered a French doctor’s memoir titled The End of My Addiction. The fix that he proposed seemed too good to be true. But her phone call with the doctor left her, and us, even more intrigued. Could this malady – so often seen as moral and spiritual - really be beaten back with a pill?

We talk to addiction researcher Dr. Anna Rose Childress, addiction psychologist Dr. Mark Willenbring, journalist Gabrielle Glaser, The National Institute of Health’s Dr. Nora Volkow, and scores of people dealing with substance abuse as we try to figure out whether we're in the midst of a sea change in how we think about addiction.

Editor's Note:

In our podcast, The Cold War, we failed to correctly credit David Wolman and Julian Smith, who wrote and reported the article on which it was based. At the time we published this podcast, we had not properly determined the extent of their role in finding and developing this story. As a result, we have removed the episode from the Radiolab archive. We did not feel a correction could rectify the problem and Radiolab honors its relationships with contributors too much to let the error remain.

What happens when you combine an axe-wielding microbiologist and a disease-obsessed historian? A strange brew that's hard to resist, even for a modern day microbe.

In the war on devilish microbes, our weapons are starting to fail us. The antibiotics we once wielded like miraculous flaming swords seem more like lukewarm butter knives.

But today we follow an odd couple to a storied land of elves and dragons. There, they uncover a 1000-year-old secret that makes us reconsider our most basic assumptions about human progress and wonder: What if the only way forward is backward?

It would seem that hackers today can do just about anything they want - from turning on the cellphone in your pocket to holding your life's work hostage. Cyber criminals today have more sophisticated tools, have learned to work collaboratively around the world and have found innovative ways to remain deep undercover in the internet's shadows. This episode, we shine a light into those shadows to see the world from the perspectives of both cybercrime victims and perpetrators.

First we meet mother-daughter duo Alina and Inna Simone, who tell us about being held hostage by criminals who have burrowed into their lives from half a world away. Along the way we learn about the legally sticky spot that unwitting accomplices like Will Wheeler find themselves in.

Then reporter and author Joseph Menn tells us about the surprisingly lucrative professional hacker structure in places throughout the former Soviet Union. Finally, the co-creator of one of the most notorious online marketplaces to ever exist speaks to us and NPR cyber-crime expert Dina Temple-Raston about how a young suburban Boy Scout can turn into a world renowned black hat hacker.

Back in 2014, Corey Knowlton paid $350,000 for a hunting trip to Namibia to shoot and kill an endangered species. He’s a professional hunter, who guides hunts all around the world, so going to Africa would be nothing new. The target on the other hand would be. And so too, he quickly found, would be the attention.

This episode, producer Simon Adler follows Corey as he dodges death threats and prepares to pull the trigger. Along the way we stop to talk with Namibian hunters and government officials, American activists, and someone who's been here before - Kenya’s former Director of Wildlife, Richard Leakey. All the while, we try to uncover what conservation really means in the 21st century.

In memory of one of our dear friends, a re-release of our last conversation with Dr. Oliver Sacks.

Scientists took about 300 years to lay out the Periodic Table into neat rows and columns. In one hour, we’re going to mess it all up.

As we're busy working on our next episode, with stories inspired by the Periodic Table of Elements, we thought we'd bring you one of its chief inspirations. As a young boy, neurologist, author and Radiolab favorite Oliver Sacks pored over the pages of the Handbook of Physics and Chemistry, fantasizing about the day that he, like the shy gas Xenon, would find a companion with whom to connect and share. That companion turned out to be the Periodic Table of the Elements itself, a relationship he's never outgrown. He introduces us to the elements that he's known and loved.

The definition of life is in flux, complexity is overrated, and humans are shrinking.

Viruses are supposed to be sleek, pared-down, dead-eyed machines. But when one microbiologist stumbled upon a GIANT virus, hundreds of times bigger than any seen before, all that went out the window. The discovery opened the door not only to a new cast of microscopic characters with names like Mimivirus, Mamavirus, and Megavirus, but also to basic questions: How did we miss these until now? Have they been around since the beginning? What if evolution could go … backwards?

A donation leads Sarah and Ross Gray to places we rarely get a chance to see. In this surprising journey, they gain a view of science that is redemptive, fussy facts that are tender, and parts of a loved one that add up to something unexpected.

Before he was even born, Sarah and Ross knew that their son Thomas wouldn’t live long. But as they let go of him, they made a decision that reverberated through a world that they never bothered to think about. Years later, after a couple awkward phone calls and an unexpected family road trip, they managed to meet the people and places for whom Thomas’ short life was an altogether different kind of gift.

Since we first aired this segment, some exciting things have happened in the Gray's world. Our producer Tracie Hunte sat down with Sarah Gray to get the low-down on what's new. Check it out here:

This is the story of a few documents that tumbled out of the secret archives of the biggest empire the world has ever known, offering a glimpse of histories waiting to be rewritten.

Hidden inside some of the world’s smallest organisms is one of the most powerful tools scientists have ever stumbled across. It's a defense system that has existed in bacteria for millions of years and it may some day let us change the course of human evolution.

Out drinking with a few biologists, Jad finds out about something called CRISPR. No, it’s not a robot or the latest dating app, it’s a method for genetic manipulation that is rewriting the way we change DNA. Scientists say they’ll someday be able to use CRISPR to fight cancer and maybe even bring animals back from the dead. Or, pretty much do whatever you want. Jad and Robert delve into how CRISPR does what it does, and consider whether we should be worried about a future full of flying pigs, or the simple fact that scientists have now used CRISPR to tweak the genes of human embryos.

As of February 24th, 2017 we've updated this story.

Reporter Karen Duffin and her father were talking one day when, just as an aside, he mentioned the Nazi prisoners of war that worked on his Idaho farm when he was a kid. Karen was shocked ... and then immediately obsessed. So she spoke with historians, dug through the National Archives and oral histories, and uncovered the astonishing story of a small town in Alabama overwhelmed by thousands of German prisoners of war. Along the way, she discovered that a very fundamental question - one that we are struggling with today - was playing out seventy years ago in hundreds of towns across America: When your enemy is at your mercy, how should you treat them? Karen helps Jad and Robert try to figure out why we did what we did then, and why we are doing things so differently now.

In December of 2009, photojournalist Lynsey Addario was embedded with a medevac team in Afghanistan. After days of waiting, one night they got the call - a marine was gravely wounded. What happened next happens all the time. But this time it was captured, picture by picture, in excruciating detail. Horrible, difficult, and at times strikingly beautiful, those photos raise some questions: Who should see them, who gets to decide who should see them, and what can pictures like that do, to those of us far away from the horrors of war and those of us who are all too close to it?

How a group of 80’s Cuban misfits found rock-and-roll and created a revolution within a revolution, going into exile without ever leaving home. In a collaboration with Radio Ambulante, reporter Luis Trelles bring us the story of punk rock’s arrival in Cuba and a small band of outsiders who sentenced themselves to death and set themselves free.

Produced by Tim Howard & Matt Kielty. With production help from Andy Mills.

All the world’s a stage. So we push through the fourth wall, pierce the spandex-ed heart of professional wrestling, and travel 400 years into the past to unmask our obsession with authenticity and our desire to walk the line between reality and fantasy.

When we talk online, things can go south fast. But they don’t have to. Today, we meet a group of social engineers who are convinced that tiny changes in wording can make the online world a kinder, gentler place. So long as we agree to be their lab rats.

Ok, yeah, we’re talking about Facebook. Because Facebook, or something like it, is more and more the way we share and like, and gossip and gripe. And because it's so big, Facebook has a created a laboratory of human behavior the likes of which we’ve never seen. We peek into the work of Arturo Bejar and a team of researchers who are tweaking our online experience, bit by bit, to try to make the world a better place. And along the way we can’t help but wonder whether that’s possible, or even a good idea.

Today, we tackle football. It’s the most popular sport in the US, shining a sometimes harsh light on so much of what we have been, what we are, and what we hope to be. Savage, creative, brutal and balletic, whether you love it or loathe it … it’s a touchstone of the American identity.

Along with conflicted parents and players and coaches who aren’t sure if the game will survive, we take a deep dive into the surprising history of how the game came to be. At the end of the 19th century, football is a nascent and nasty sport. The sons of the most powerful men in the country are literally knocking themselves out to win these gladiatorial battles. But then the Carlisle Indian School, formed in 1879 to assimilate the children and grandchildren of the Native American men who fought the final Plains Wars, fields the most American team of all. The kids at Carlisle took the field to face off against a new world that was destroying theirs, and along the way, they changed the fundamentals of football forever.

Invisibilia has an upcoming episode about categories, so Alix tells us a story about two very basic categories: boy and girl. We've heard lots of stories about the sometimes blurry boundaries between boy and girl, but Alix introduces us to someone who experiences those categories in a way that was totally, completely new to us.

This episode, we make three earnest, possibly foolhardy, attempts to put a price on the priceless. We figure out the dollar value for an accidental death, another day of life, and the work of bats and bees as we try to keep our careful calculations from falling apart in the face of the realities of life, and love, and loss.

Buttons are usually small and unimportant. But not always. Sometimes they are a portal to power, freedom, and destruction. Today we thread together tales of taking charge of the little things in life, of fortunes made and lost, and of the ease with which the world can end.

Confused? Push the button marked Play.

In the wake of public tragedy there is a space between the official narrative and the stories of the people who experienced it. Today, we crawl inside that space and question the role of journalists in helping us move on from a traumatic event.

NPR's East Africa correspondent Gregory Warner takes us back to the 2013 terrorist attacks on the Westgate Mall in Nairobi, Kenya. Warner reported on the attack as it happened, listening to eyewitness accounts, sorting out the facts, establishing the truth. But he's been been wrestling with it ever since as his friends and neighbors try not only to put their lives back together, but also try to piece together what really happened that day.

The greatest mysteries have a shadowy figure at the center—someone who sets things in motion and holds the key to how the story unfolds—Patient Zero. This hour, Radiolab hunts for Patient Zeroes of all kinds and considers the course of an ongoing outbreak.

We start with the story of perhaps the most iconic Patient Zero of all time: Typhoid Mary. Then, we dive into a molecular detective story to pinpoint the beginning of the AIDS epidemic, and we re-imagine the moment the virus that caused the global pandemic sprang to life. After that, we update the show with a quick look at the very current Ebola outbreak in west Africa. In the end, we're left wondering if you can trace the spread of an idea the way you can trace the spread of a disease and find ourselves faced with competing claims about the origin of the high five.

Dennis Conrow was stuck. After a brief stint at college, he’d passed most of his 20’s back home with his parents, sleeping in his childhood room. And just when he finally struck out on his own, fate intervened. He lost both his parents to cancer. So Dennis was left, back in the house, alone. Until one night when a group of paranormal investigators showed up at his door and made him realize what it really means for a house, or a man, to be haunted.

How close can words get you to the truth and feel and force of life? That's the question poking at our ribs this hour, as we wonder how it is that the right words can have the wrong meanings, and why sometimes the best translations lead us to an understanding that's way deeper than language. This episode, 8 stories that play out in the middle space between one reality and another — where poetry, insult comedy, 911 calls, and even our own bodies work to close the gap.
