Until now, the fastest vaccine ever made - for mumps - took four years. And while our current effort to develop a covid-19 vaccine involves thousands of people working around the clock, the mumps vaccine was developed almost exclusively by one person: Maurice Hilleman. Hilleman cranked out more than 40 other vaccines over the course of his career, including 8 of the 14 routinely given to children. He arguably saved more lives than any other single person. And through his work, Hilleman embodied the instincts, drive, and guts it takes to marshall the human body’s defenses against a disease. But through him we also see the struggle and the costs of these monumental scientific efforts.

What if someone asked you to get infected with the COVID-19 virus, deliberately, in order to speed up the development of a vaccine? Would you do it? Would you risk your life to save others?

For months, dozens of companies have been racing to create coronavirus vaccines. Finally, three have done it. But according to the experts, we’re not out of the woods yet; we’ll need several vaccines to satisfy the global demand. One way to speed up the development process is a controversial technique called a human challenge trial, in which human subjects are intentionally infected with the virus. Senior correspondent Molly Webster gets the lowdown from Public News Service reporter Laura Rosbrow-Telem and then tracks down some of the tens of thousands of people who have volunteered to participate in a challenge trial.

Lies, liars, and lie catchers. This hour of Radiolab asks if it's possible for anyone to lead a life without deception.

In the days after the US Presidential election was called for Joe Biden, many supporters of Donald Trump are crying foul. Voter fraud. And a key piece of evidence? A century-old quirk of math called Benford’s Law. We at Radiolab know Benford’s Law well, and have covered it before. In this political dispatch, Latif and Soren Sherlock their way through the precinct numbers to see if these claims hold up. Spoiler: they don’t. But the reason why is more interesting than you’d expect.

Walter Mebane, “Inappropriate Applications of Benford’s Law Regularities to Some Data from the 2020 Presidential Election in the United States”

In the 1996 election, Bill Clinton had a problem. The women who came out in droves for him in ‘92, split their vote in the ‘94 midterms, handing over control of the House and the Senate to the Republican Party. As his team stared ahead at his re-election bid, they knew they had to win those women back. So, after a major polling effort to determine who exactly their undecided ladies were, Clinton turned his focus toward the most important swing vote in the election: the soccer moms.

The soccer mom ushered in a new era of political campaigning, an era of slicing and dicing the electorate, engineering the (predominately white) voting bloc characters that campaigns have chased after. Security Moms. Nascar Dads. Joe Six Pack. Walmart Moms.

But what about everyone else? What about the surprisingly swingable corners of this country without a soccer mom in sight? Inspired by this exceedingly cool interactive map from Politico, we set out on a mission to make an audio-map of our own. We asked pollsters, reporters and political operatives in swing states: what slice of your population is up for grabs? A slice that no one talks about? In this episode, we crawl inside the places that might hold our country’s future in its hands, all the while asking: are these slices even real? Are there people inside them that might swing this election?

Baboon troops. We all know they’re hierarchical. There’s the big brutish alpha male who rules with a hairy iron fist, and then there’s everybody else. Which is what Meg Crofoot thought too, before she used GPS collars to track the movements of a troop of baboons for a whole month. What she and her team learned from this data gave them a whole new understanding of baboon troop dynamics, and, moment to moment, who really has the power.

There’s plenty of speculation about what Donald Trump might do in the wake of the election. Would he dispute the results if he loses? Would he simply refuse to leave office, or even try to use the military to maintain control? Last summer, Rosa Brooks got together a team of experts and political operatives from both sides of the aisle to ask a slightly different question. Rather than arguing about whether he’d do those things, they dug into what exactly would happen if he did. Part war game part choose your own adventure, Rosa’s Transition Integrity Project doesn’t give us any predictions, and it isn’t a referendum on Trump. Instead, it’s a deeply illuminating stress test on our laws, our institutions, and on the commitment to democracy written into the constitution.

With the recent passing of Ruth Bader Ginsburg, there's been a lot of debate about how much power the Supreme Court should really have.

We think of the Supreme Court justices as all-powerful beings, issuing momentous rulings from on high. But they haven’t always been so, you know, supreme. On this episode, we go all the way back to the case that, in a lot of ways, started it all.

What are the police for? Producer B.A. Parker started wondering this back in June, as Black Lives Matter protests and calls to “defund the police” ramped up. The question led her to a wild story of a stabbing on a New York City subway train, and the realization that, according to the law, the police don’t always have to protect us. Producer Sarah Qari joins Parker to dig into the legal background, which takes her all the way up to the Supreme Court... and then all the way back down to on-duty officers themselves.

This episode contains strong language and graphic violence.

Coronasomnia is a not-so-surprising side-effect of the global pandemic. More and more of us are having trouble falling asleep. We wanted to find a way to get inside that nighttime world, to see why people are awake and what they are thinking about.

We lost a legend. Supreme Court Justice Ruth Bader Ginsburg died on September 18th, 2020. She was 87. In honor of her passing we are re-airing the More Perfect episode dedicated to one of her cases, because it offers a unique portrait of how one person can make change in the world.

This is the story of how Ginsburg, as a young lawyer at the ACLU, convinced an all-male Supreme Court to take discrimination against women seriously - using a case on discrimination against men.

Today, we return to the lab of neuroscientist Li-Huei Tsai, which brought us one of our favorite stories from four years ago - about the power of flashing lights on an Alzheimer’s-addled (mouse) brain. In this update, Li-Huei tells us about her team’s latest research, which now includes flashing sound, and ways in which light and sound together might retrieve lost memories. This new science is not a cure, and is far from a treatment, but it’s a finding so … simple, you won’t be able to shake it. Come join us for a lab visit, where we’ll meet some mice, stare at some light, and come face-to-face with the mystery of memory. We can promise you: by the end, you’ll never think the same way about Christmas lights again. Or jingle bells.

Molly's note about the image:

Those neon green things in the image are microglia, the brain’s immune cells, or, as we describe them in our episode, the janitor cells of the brain. Straight from MIT’s research files, this image shows microglia who have gotten light stimulation therapy (one can only hope in the flicker room). You can see their many, super-long tentacles, which would be used to feel out anything that didn’t belong in the brain. And then they’d eat it!

Six years ago, a new infection began popping up in four different hospitals on three different continents, all around the same time. It wasn’t a bacteria, or a virus. It was ... a killer fungus. No one knew where it came from, or why. Today, the story of an ancient showdown between fungus and mammals that started when dinosaurs disappeared from the earth. Back then, the battle swung in our favor (spoiler alert!) and we’ve been hanging onto that win ever since. But one scientist suggests that the rise of this new infectious fungus indicates our edge is slipping, degree by increasing degree.

How close can words get you to the truth and feel and force of life?

This episode, a bunch of 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.

First things first: our very own Latif Nasser has an exciting new show on Netflix. He talks to Jad about the hidden forces of the world that connect us all.

Then, with an eye on the upcoming election, we take a look back: at two pieces from More Perfect Season 3 about Constitutional amendments that determine who gets to vote.

Former Radiolab producer Julia Longoria takes us to Washington, D.C. The capital is at the heart of our democracy, but it’s not a state, and it wasn’t until the 23rd Amendment that its people got the right to vote for president. But that still left DC without full representation in Congress; D.C. sends a "non-voting delegate" to the House. Julia profiles that delegate, Congresswoman Eleanor Holmes Norton, and her unique approach to fighting for power in a virtually powerless role.

Second, Radiolab producer Sarah Qari looks at a current fight to lower the US voting age to 16 that harkens back to the fight for the 26th Amendment in the 1960s. Eighteen-year-olds at the time argued that if they were old enough to be drafted to fight in the War, they were old enough to have a voice in our democracy. But what about today, when even younger Americans are finding themselves at the center of national political debates? Does it mean we should lower the voting age even further?

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.

Today we revisit our story on Facebook and its rulebook, looking at what’s changed in the past two years and exploring how these rules will impact the 2020 Presidential Election.

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?

Back in the 1950s, facing the threat of nuclear annihilation, federal officials sat down and pondered what American life would actually look like after an atomic attack. They faced a slew of practical questions like: Who would count the dead and where would they build the refugee camps? But they faced a more spiritual question as well. If Washington DC were hit, every object in the the National Archives would be eviscerated in a moment. Terrified by this reality, they set out to save some of America’s most precious stuff.

Today, we look back at the items our Cold War era planners sought to save and we ask the question: In the year 2020, what objects would we preserve now?

One day in 1961, the famous physicist Richard Feynman stepped in front of a Caltech lecture hall and posed this question to a group of undergraduate students: “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence was passed on to the next generation of creatures, what statement would contain the most information in the fewest words?” Now, Feynman had an answer to his own question - a good one. But his question got the entire team at Radiolab wondering, what did his sentence leave out? So we posed Feynman’s cataclysm question to some of our favorite writers, artists, historians, futurists - all kinds of great thinkers. We asked them, “What’s the one sentence you would want to pass on to the next generation that would contain the most information in the fewest words?” What came back was an explosive collage of what it means to be alive right here and now, and what we want to say before we go.

More than a million people have caught Covid-19, and tens of thousands have died. But thousands more have survived and recovered. A week or so ago (aka, what feels like ten years in corona time) producer Molly Webster learned that many of those survivors possess a kind of superpower: antibodies trained to fight the virus. Not only that, they might be able to pass this power on to the people who are sick with corona, and still in the fight. Today we have the story of an experimental treatment that’s popping up all over the country: convalescent plasma transfusion, a century-old procedure that some say may become one of our best weapons against this devastating, new disease.

It began with a tweet: “EVERY DAY IS IGNAZ SEMMELWEIS DAY.” Carl Zimmer — tweet author, acclaimed science writer and friend of the show — tells the story of a mysterious, deadly illness that struck 19th century Vienna, and the ill-fated hero who uncovered its cure … and gave us our best weapon (so far) against the current global pandemic.

In a recent Radiolab group huddle, with coronavirus unraveling around us, the team found themselves grappling with all the numbers connected to COVID-19. Our new found 6 foot bubbles of personal space. Three percent mortality rate (or 1, or 2, or 4). 7,000 cases (now, much much more). So in the wake of that meeting, we reflect on the onslaught of numbers - what they reveal, and what they hide.

The Other Latif

Radiolab’s Latif Nasser always believed his name was unique, singular, completely his own. Until one day when he makes a bizarre and shocking discovery. He shares his name with another man: Abdul Latif Nasser, detainee 244 at Guantanamo Bay. The U.S. government paints a terrifying picture of The Other Latif as Al-Qaeda’s top explosives expert, and one of the most important advisors to Osama bin Laden. Nasser’s lawyer claims that he was at the wrong place at the wrong time, and that he was never even in Al-Qaeda. This clash leads Radiolab’s Latif into a years-long investigation, picking apart evidence, attempting to separate fact from fiction, and trying to uncover what this man actually did or didn’t do. Along the way, Radiolab’s Latif reflects on American values and his own religious past, and wonders how his namesake, a fellow nerdy, suburban Muslim kid, may have gone down such a strikingly different path.

Episode 6: Washington, D.C.

Despite being cleared for transfer back to his family in Morocco in 2016, Abdul Latif Nasser remains stuck at Guantanamo Bay. Why? Latif talks to some of the civil servants actually responsible for Abdul Latif’s transfer and they tell him a dramatic story of what went on behind the scenes at some of the highest levels of government. It’s a surprisingly riveting story of paperwork, where what’s at stake is not only the fate of one man, but also the soul of America.

Episode 5: Cuba-ish

Latif heads to Guantanamo Bay to try to speak to his namesake. Before he gets there, he attempts to answer a seemingly simple question: why Cuba? Why in the world did the United States pick this sleepy military base in the Caribbean to house “the worst of the worst”? He tours the “legal equivalent of outer space,” and against all odds, manages to see his doppelgänger… maybe.

BONUS EPISODE

Since we released the first episode of The Other Latif, we’ve been contacted by many new sources. Which is great! But it also means we need a little extra time to cobble together Episodes 5 and 6. So while we wait, Jad and Latif chat about Abdul Latif’s response to the series, a character who fell out of episode 4, and a tiny moment in Latif’s youth that helped put him on the path he’s on now.

Episode 4: Afghanistan

Latif investigates the mystery around Abdul Latif’s classified time in Afghanistan. He traces the government’s story through scrappy training camps, bombed out Buddhas, and McDonald’s apple pies to the very center of the Battle of Tora Bora. Could Abdul Latif have helped the most sought-after and hated terrorist in modern history, Osama bin Laden, escape? The episode ends with a bombshell jailhouse interview with Abdul Latif, the most reliable evidence yet of what was going on in this man’s mind in the months after 9/11.

Episode 3: Sudan

Latif turns his focus to Sudan, where his namesake spent time working on a sunflower farm. What could be suspicious about that? Latif scrutinizes the evidence to try to discover whether - as Abdul Latif’s lawyer insists - it was just an innocent clerical job, or - as the government alleges - it was where he decided to become an extremist fighter.

Episode 2: Morocco

Latif travels to Abdul Latif’s hometown of Casablanca, Morocco, to try and find out: was he radicalized? And if so, how? Latif begins by visiting the man’s family, but the family’s reaction to him gets complicated as Latif digs for the truth. He finds out surprising information on a political group Abdul Latif joined in his youth, his alleged onramp to extremism. Tensions escalate when Latif realizes he’s being tailed.

Episode 1: My Namesake

We hear the evidence against Abdul Latif Nasser -- at least the evidence that has been leaked or declassified -- and we meet Shelby Sullivan-Bennis, his attorney, who contests more or less every government claim against him. Sullivan-Bennis walks us through the excruciating process that came close to releasing Abdul Latif Nasser in the waning days of the Obama administration, but fell apart at the last minute. He is now technically a free man -- he was cleared for transfer home in 2016 -- yet he remains stuck at Guantanamo Bay, thanks in part to a Presidential Tweet.

Right now, at this very moment, all across the planet, there are 7.6 billion human beings eating, breathing, sleeping, brushing their teeth, walking their dogs, drinking coffee, walking down the street or running onto the subway or hopping in their car, maybe reading a summary of a podcast they’re about to hit play on … and the number is only going up. Everyday 386,000 babies are born (16,000 an hour). We’re adding a billion new people every 12 years.

So here’s a question you’ve probably never thought about: Are there more people alive right now than have ever lived on the planet in history? Do the living outnumber the dead? Robert got obsessed with this odd question, and in this episode we bring you the answer. Or, well, answers.

Here's a simple question: When an animal disappears in the winter, where does it go? Oddly enough, this question completely stumped European scientists for thousands of years. And even today, the more we learn about the comings and goings of the animals, the deeper the mystery seems to get. We visit a Bavarian farm with an 11 year old, follow warblers and wildebeests around the world, and get a totally new kind of view of the pulsing flow of animals across the globe.

From a piece of the Wright brother's plane to a child’s sugar egg, today: Things! Important things, little things, personal things, things you can hold and things that can take hold of you. This hour, we investigate the objects around us, their power to move us, and whether it's better to look back or move on, hold on tight or just let go.

Deep fake videos have the potential to make it impossible to sort fact from fiction. And some have argued that this blackhole of doubt will eventually send truth itself into a death spiral. But a series of recent events in the small African nation of Gabon suggest it's already happening.

Today, we follow a ragtag group of freedom fighters as they troll Gabon’s president - Ali Bongo - from afar. Using tweets, videos and the uncertainty they can carry, these insurgents test the limits of using truth to create political change and, confusingly, force us to ask: Can fake news be used for good?

Today on Radiolab, we're bringing you the fourth episode of Jad's special series, Dolly Parton's America. In this episode, Jad goes back up the mountain to visit Dolly’s actual Tennessee mountain home, where she tells stories about her first trips out of the holler. Back on the mountaintop, standing under the rain by the Little Pigeon River, the trip triggers memories of Jad’s first visit to his father's childhood home, and opens the gateway to dizzying stories of music and migration.

Coming off our adventures with Square Dancing, and Jad's dive into the world of Dolly Parton, we look back at one our favorites. About a decade ago, we found out that American country music is surprising popular in places like Zimbabwe, Thailand, and South Africa. Aaron Fox, an anthropologist of music at Columbia University, tells us that quite simply, country music tells a story that a lot of us get. Then, intrepid international reporter Gregory Warner takes us along on one of his very first forays into another country, where he discovers an unexpected taste of home.

People have been doing the square dance since before the Declaration of Independence. But does that mean it should be THE American folk dance? That question took us on a journey from Appalachian front porches, to dance classes across our nation, to the halls of Congress, and finally a Kansas City convention center. And along the way, we uncovered a secret history of square dancing that made us see how much of our national identity we could stuff into that square, and what it means for a dance to be of the people, by the people, and for the people.

Radiolab creator and host Jad Abumrad spent the last two years following around music legend Dolly Parton, and we're here to say you should tune in! In this episode of Radiolab, we showcase the first of Jad's special series, Dolly Parton's America. In this intensely divided moment, one of the few things everyone still seems to agree on is Dolly Parton—but why? That simple question leads to a deeply personal, historical, and musical rethinking of one of America’s great icons.

We begin with a simple question: How did the queen of the boob joke become a feminist icon? Helen Morales, author of “Pilgrimage to Dollywood,” gave us a stern directive – look at the lyrics! So we dive into Dolly’s discography, starting with the early period of what Dolly calls “sad ass songs” to find remarkably prescient words of female pain, slut-shaming, domestic violence, and women being locked away in asylums by cheating husbands. We explore how Dolly took the centuries-old tradition of the Appalachian “murder ballad”—an oral tradition of men singing songs about brutally killing women—and flipped the script, singing from the woman’s point of view. And as her career progresses, the songs expand beyond the pain to tell tales of leaving abuse behind.

How can such pro-woman lyrics come from someone who despises the word feminism? Dolly explains.

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.

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.

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.

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.

Using high-powered ballistics experiments, fancy computer algorithms, and good old-fashioned ancient geology, scientists have woven together a theory about the extinction of the dinosaurs that is so precise, so hot, so instantaneous, as to seem unimaginable.

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.

When Nancy Holten was 8 years old her mom put her in a moving van. She fell asleep, woke up in Switzerland, and she's been there ever since. Nancy is big into animal rights, crystals, and various forms of natural and holistic healing. She’s also a viral sensation: the Dutch woman apparently so annoying, her Swiss town denied her citizenship. In this episode we go to the little village of Gipf-Oberfrick to meet Nancy, talk with the town, and ask the question: what does it mean and what does it take to belong to a place?

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? Today on Radiolab, a goof on a goon turns into a parable of the agony and the ecstasy of the internet, and democracy in the age of Boaty McBoatface.

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.

Today on Radiolab, we're playing the fourth and final episode of a series Jad worked on called UnErased: The history of conversion therapy in America.

Imagine... You’re openly gay. Then, you become the leader of the largest ex-gay organization and, under your leadership, many lives are destroyed. You leave that organization, come out as gay - again - and find love. Do you deserve to be happy? This is a story of identity, making amends and John Smid’s reckoning with his life.

Today on Radiolab, we're playing part of a series that Jad worked on called UnErased: The history of conversion therapy in America.

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).

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.

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.

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.

But inside it, an epic struggle plays out, as a nomadic band of cells marches toward a mysterious destiny, with the future of humanity resting on their microscopic shoulders.

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.

CORRECTION: An earlier version of this piece incorrectly stated that Silvestre Reyes's brother died in a car accident in 1968; it was actually his father who died in the accident. 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.

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.

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.

Today we take a quick look up at a hole in the sky and follow an old story as it travels beyond the reach of the sun.

Today, paranoia sets in: we head to The Ceremony, the top-secret, three-day launch of a new currency, wizards and math included. Halfway through, something strange happens.

A new tussle over an old story, and some long-held beliefs, with neurologist and author Robert Sapolsky.

Four years ago, we did a story about a man with a starling obsession that made us question our ideas of responsibility and justice. We thought we’d found some solid ground, but today Dr. Sapolsky shows up and takes us down a rather disturbing rabbit hole.

What happens when doing what you want to do means giving up who you really are?

We travel to Venice, Italy with reporters Kristen Clark and David Conrad, where they meet gondolier Alex Hai. On the winding canals in the hidden parts of Venice, we learn about the nearly 1000-year old tradition of the Venetian Gondolier, and how the global media created a 20-year battle between that tradition and a supposed feminist icon.

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.

Today, a hidden power that is either the cornerstone of our democracy or a trapdoor to anarchy. Should a juror be able to ignore the law? From a Quaker prayer meeting in the streets of London, to riots in the streets of LA, we trace the history of a quiet act of rebellion and struggle with how much power “we the people” should really have.

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.

Produced by Simon Adler with help from Only Human: Amanda Aronczyk, Kenny Malone, Jillian Weinberger and Elaine Chen.

Neil deGrasse Tyson's newest book is called "Astrophysics for People in A Hurry."

*** 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.

With all the recent talk about HBO's upcoming film, we decided it would be good time to re-run our story of one woman's medically miraculous cancer cells, and how Henrietta Lacks changed modern science and, eventually, her family's understanding of itself.

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.

Produced and reported by Matt Kielty.

For the full presentation of Ben Montgomery's reporting please visit the Tampa Bay Times' 'Why Do Cops Shoot?" We can't recommend it highly enough.

Jad and Robert talk to Ben about what he found, crunch some numbers, and then our reporter Matt Kielty takes a couple files off Ben's desk and brings us the stories inside them - from a network of grief to a Daytona police chief.

And next week, we bring you another, very different story of a police encounter gone 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 officers 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.

Today we travel from the storage rooms of the Smithsonian to the sandy beaches of Guadeloupe, chasing the tale of this trash can tipping critter. All the while trying to uncover what it means to be special.

Produced and reported by Simon Adler.

Special thanks to Sally Stainier and Allie Pinel for all their help translating in Guadeloupe and New York respectively.

We love to share great radio, even if we didn’t make it. Today, On the Media’s Brooke Gladstone tells Jad and Robert about a mammoth project they launched to take a critical look at the tales we tell ourselves when we talk about poverty.

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.

Go check out the full series, it’s well worth it. You can hear all 5 episodes of Busted here or subscribe to On the Media in iTunes (or wherever you get your podcasts) to listen to this series or all their other great work.

"Busted: America’s Poverty Myths" was produced by Meara Sharma and Eve Claxton and edited by Katya Rogers. They produced the series in collaboration with WNET’s Chasing the Dream; poverty and opportunity in America.
