When medical mistakes happen, patients and their families often find themselves at a loss trying to figure out exactly what went wrong. Something bad happened. And then, communication drops; there's no real explanation, and no apology. Suddenly, everybody seems on guard. Health care providers can often feel bound by an imposed cone of silence that's designed to protect them and their institution, but makes it impossible to fully face up to their mistake, or have open conversations about preventing future ones.
On this episode, we explore the breaking of that silence, along with new solutions to avoid medical errors. We hear stories about what prompted one surgeon to go public after performing the wrong procedure, how the death of a young woman prompted her parents to try and change the system, and an investigation into an OB-GYN and the trail of injured women left in his wake.

Every day, we hear about countless environmental threats — from air pollution and microplastics, to deforestation and global warming. And a lot of us feel overwhelmed by the scale of these problems, and helpless to enact global big-picture solutions.

But small, everyday decisions matter too — and they add up. How you do your laundry, how warm or cool you keep your home, what you eat for lunch, what kinds of products you buy and or how you sort your trash — all of them have the potential to make a big difference.

On this special Earth Day episode, we look at everyday choices that can lead to greener living. We hear stories about laundry detergents, and how we can clean our clothes without hurting the planet, what it'll take for plant-based meat to make it to the big leagues, and an innovation that could revolutionize recycling as we know it.

Over the past few decades, Latinos have become the largest racial or ethnic minority in the United States, making up nearly 20 percent of the country's population. Despite that, many Latinos feel alienated by our medical system, due to cultural and language barriers, and a lack of Latino physicians — and those barriers can have a real impact on their overall health.
On this episode, we look for solutions to provide better care to Latino communities and patients. We hear stories about one physician's bold initiative to bridge the language gap between doctors and farmworkers, new approaches to help victims of gun violence, and a national effort to increase the number of Latino physicians.

It sneaks up on us while we're sitting in traffic, or waiting at the doctor's office, or doing our taxes — boredom, that restless feeling of dissatisfaction that arises when we harbor "the desire for desires," as Leo Tolstoy said.
At the same time, we're living in an age of never-ending stimulation, all at our fingertips — texting, social media, 24-hour news, and streaming galore. But despite this constant content consumption, we're still getting bored — maybe even more so than ever. We find ourselves hopping from tab to tab, scrolling through Instagram while watching a show, tuning out of meetings to check our email. And now some researchers are worried that all this stimulation could be changing our brains.

On this rebroadcast episode, we look at boredom in the age of information overload, and whether or not it's really good for us and our brains. We hear stories about what happened when two reporters quit their digital addictions for four weeks, a monk who took his search for boredom to the ultimate extreme, and why there's value to the slow pace of baseball.

On April 8, a swath of North America will be treated to a rare and spectacular sight — a total solar eclipse; in some places, the first in more than a century, and the last for at least another 20 years. The path of totality, where it's possible to see the moon completely block out the sun, stretches in a narrow ribbon from Mexico, through Texas, all the way to Maine.
It's an event that eclipse chasers have been anticipating for years. On this special episode, we find out why so many people call total solar eclipses a life-changing experience, and why they will go to great lengths to witness this fleeting spectacle of nature. We'll hear what scientists are hoping to learn during this brief but important moment, and we'll pay tribute to the celestial body that makes the eclipse possible: the moon.

Identity's a complicated thing — a mixture of nurture and nature, ethnicity, gender, culture, conscious decisions, coincidences, and more. In many ways, though, who we think we are boils down to the stories we tell ourselves; stories based on our origins, our families, and how we came to be.
But what happens when those stories change? When we discover that the narrative of our lives is completely different from what we've always believed?

On this episode, we explore stories of identity, and what happens when long-buried secrets are uncovered. We hear about a journalist who discovered that his father wasn't who he thought he was, one woman's search for her childhood self in the records of a long-running experiment, and how a fateful medical decision changed the future of a baby born in 1986.

It's been four years since COVID-19 struck, transforming our modern world in ways we'd never seen before — and we're still processing the aftershocks. The pandemic exposed fault lines lurking beneath the surface of our everyday lives — friendships and bonds that weren't as strong as we thought; political rifts that turned into chasms; shifts in our fundamental beliefs of who we should trust, and what rules we should follow. It showed us how fragile we are — as human beings, and as a global community.
Now, we find ourselves trying to pick up the pieces — to understand what happened, and what we can do better next time. On this episode, we explore the major changes caused by the pandemic, what we can learn from them, and how we can move forward. We hear stories about one man's dogged search for a treatment for his long COVID, how the pandemic both hurt and revived the field of public health, and how to repair relationships that became frayed or broken by the pressures of the pandemic.

Know the signs of depression. Recognize symptoms of anxiety. Pay attention to your friend's changing moods. There's been a push to raise mental health awareness for decades, and now, the topic is everywhere. It's leading the charts on social media sites, and everybody from celebrities to politicians to sports superstars are talking about it more openly. At the same time, it seems like our overall mental health is declining, as more and more people report having mental health issues. On this episode, we explore how the field of mental health is changing and adapting. We'll find out what traditionally trained therapists make of mental health advice on social media, why some experts argue that too much awareness can backfire, and why mental illness can be so tricky to diagnose. Also, one woman's quest to stay on her ADHD medications as shortages drag on.

In 1944, a brilliant, young Harvard physics student named Ted Hall was recruited to work on the super-secret mission that had already assembled the country's top scientists: the Manhattan Project. Soon, Hall was on his way to Los Alamos, where he worked on the implosion mechanism for the nuclear bomb. As the project started to succeed, Hall became increasingly concerned that it would spell disaster for the world, especially if the U.S. were the only country to have nuclear capacity. So, at the age of 18, Hall decided that he needed to do something, and he became a spy for the Soviets. Hall may have been an incredible physicist, but he was not the stealthiest of spies. Still, he was never officially caught or charged. On this episode, investigative journalist Dave Lindorff details why Ted chose this path and how he managed to evade intelligence agencies. Lindorff's new book is called, "Spy for No Country: The Story of Ted Hall, the Teenage Atomic Spy Who May Have Saved the World." We'll also hear about the state of America's nuclear arsenal today and find out why some experts argue it needs a big upgrade.

If you're training to become a physician, your first patient is usually dead. In fact, "first patient" is what med students call the human cadavers that they work on in anatomy class — when they first learn to make careful incisions, and lay eyes on the beautiful intricacies of bone, muscle, blood vessels, and organs that make our bodies work.
Human cadavers have long played a crucial role in medicine and science. They not only teach generations of doctors about the human body — they allow researchers to learn valuable lessons about everything from the causes of rare diseases to the effects of how we live our lives. But how do bodies end up on dissection tables in the first place? What can they still teach us? And why do people choose to donate their remains?

On this episode, we explore bodies donated to science — how they're used, why they're so important, and why people make this choice for their remains. We hear stories about one woman's mission to recruit future medical cadavers, and how 19th century medical schools got involved in body snatching. We'll take a closer look at a program that connects med students to the families of their "first patients," and find out why one firefighter has opted for a future in the Body Worlds exhibition.

You can feel it coming on — your face flushes hot, maybe your fists clench, your heartbeat speeds up and blood pressure rises. It's rage — and it can go from zero to red-hot in a matter of seconds. Best-case scenario, it disappears just as fast. Worst-case scenario — it completely takes over. It's normal to feel angry when you or somebody else has been wronged, mistreated, or hurt. But even justified rage can become destructive, like a wrecking ball ruining careers and relationships. So, how do we handle these fiery emotions when they erupt? On this episode — how to deal with anger and rage. We learn about healthy ways of expressing our ire; the rise of "rage rooms" and what psychologists have to say about them; and what causes toddlers to throw such terrible tantrums.

It can show up as a spark or a lightning bolt; a glance or a touch; an easy rapport or butterflies in your stomach. Attraction — it's a feeling we know when we experience it, but we're often not sure exactly what fuels it. Is it about looks or personality? Psychology or chemistry? Instant fireworks or long-term compatibility? On this episode, we explore the mysteries of attraction — what kindles it, what kills it, and why we're often totally wrong about who we might be attracted to. We talk with a leading attraction researcher about the factors that determine attraction, and why he often advises people to follow their gut. We find out what dating apps — and the massive amounts of data they gather — are teaching researchers about who we're drawn to and why. And we hear the story of a couple whose mutual attraction changed over time — and why that turned out to be a good thing.

Medical records are an important part of health care. They create a history of past issues, test results, and medications. They paint a picture of somebody's general health. Patients now have more access than ever before to their records, and these changes have come with some growing pains — like receiving test results straight from the lab, before their doctor can review them, or discovering mistakes. On this episode, we crack open those medical records to get a better sense of how they can help and hinder care. We'll hear about how physicians struggle to access different parts of the record to create a cohesive picture of a patient's health. We dig into issues around law enforcement accessing these records, and why they're so valuable to hackers.

After covering the 2016 U.S. presidential election, reporter Jeff Horwitz knew that "something really weird was going on," that social media sites, especially Facebook, had played a role in shaping the election. But how — exactly? In his new book, "Broken Code: Inside Facebook and the Fight to Expose Its Harmful Secrets," Horwitz details his chase to crack open this notoriously secretive black box that is Facebook. Host Maiken Scott talks to Horwitz about the powerful algorithms that favored engagement above all else, that not just amplified specific content, but started to shape everything from what we see, to what we post, to how politicians design their campaigns. Horwitz covers technology for The Wall Street Journal and was one of the reporters on the award-winning series "The Facebook Files."

Twenty years ago, a group of college sophomores created a website that would end up changing the world — fundamentally altering how we connect with other people, how much we know about each other, and how we curate our existence. That website was Facebook.
In the years since, Facebook quickly grew from a quirky site for college students to a global powerhouse — one that can affect everything from how we feel about ourselves to the outcomes of elections.
On this episode, a look at Facebook as it turns 20 — its history, its ongoing impact, and what we really know about how it operates. We hear stories about a curious coincidence linking Facebook to a defunct government surveillance project, why many researchers have mixed feelings about Facebook, and how the website's ever-changing features transformed the lives and mental health of young people.

More than a third of Americans use complementary and alternative medicine, ranging from acupuncture to herbalism, Ayurveda to homeopathy. But despite its growing popularity, complementary and alternative medicine remains, for the most part, outside the Western medical mainstream — regarded by some as fringe, and by others as straight-up quackery. Despite that, many researchers and supporters have been trying to gain a deeper understanding of medical practices from around the world, and to incorporate them into our health care system. And that's led to more questions: Which practices work, and for what conditions? How do they work? And how do we measure and standardize treatments when they're removed from their cultural contexts? On this episode, we step outside the boundaries of Western medicine to explore those questions. We hear stories about a mysterious Vodou treatment, the struggle to bring acupuncture into the medical mainstream, and answers to Western skeptics.

Humans crave certainty — in science and politics, in our lives and our leaders, in our decisions and our futures. We find comfort in knowing the facts, and we fear the murky unknown. In the age of information, we've grown increasingly unnerved by uncertainty and do everything we can to mitigate that anxiety. We do research online, play out scenarios in our heads, make plans A, B, and C — imagining that if we can just prepare well enough, everything will be OK. But in her latest book, "Uncertain: The Wisdom and Wonder of Being Unsure," author and journalist Maggie Jackson makes the case for an opposite way of being — embracing the unknown as an invitation to pause, an opportunity for growth and innovation. On this episode, we talk with Jackson about her book, and what science teaches us about living — and even thriving — amid uncertainty. We also hear stories about one reporter's quest to make a life-changing decision while filled with doubt, and how saying "yes" to the unknown changed an introvert's life.

But as these worlds grow bigger, more intense, and consuming, they're also raising questions about what this new future will look like.We all know things are going to be different — but how? Will we soon have entirely new and far more fabulous lives in the virtual realm? Or will things feel surprisingly similar and mundane? How will a computer-generated life intersect with real life?On this episode: virtual worlds, virtual lives, and how they're changing our reality. We hear stories about Second Life — and the surprising political power structures that have emerged there; what happens when romantic relationships with AI go bad; and how increasingly realistic gaming worlds have led to the emerging discipline of archaeogaming.

It's the goosebumps you get at the crescendo of your favorite song; the stupefying wonder that comes with witnessing a birth or a death; the astonishing mystery we feel when gazing at the vast night sky. This is awe — a complex, often overwhelming emotion that can elicit everything from pleasure and connectedness to a crawling sense of uncertainty. Moments of awe can create unforgettable memories — and they can have a lasting impact on our minds and the way we interact with others. One of the leading scientists studying awe is Dacher Keltner, a University of California, Berkeley psychologist, who's dedicated the past 15 years to investigating the origins and effects of this emotion. On this episode, we talk with Keltner about his new book "Awe: The New Science of Everyday Wonder and How it Can Transform Your Life." He discusses his own, very personal experience of awe amid profound grief, the ability of awe to transform our experience of the world, and how we can cultivate awe on a daily basis. We also hear from listeners about their experiences of awe, and listen back to a story about how voyages to space change the way astronauts perceive life, their relationships, and Earth as a whole.

We all know that exercise is good for us — for both our bodies and our minds — but motivating yourself to hit the gym, take a run, or even go for a walk sometimes feels like the hardest thing in the world. There are constant rebuttals that arise in our minds: We're too busy. We're too tired. We need a break — we'll start next week. At the same time, we're bombarded by messages from people who are all about fitness — influencers with seemingly perfect bodies and a healthy glow, who convince us that we too can get into shape. It's a habit that many of us try to cultivate — yet often seem to hit a wall. On this episode, we look at the science of fitness, the evolution of cultural messages surrounding exercise, and how we can overcome inertia to start fitting it into our lives. We'll hear about how exercise affects our mood and overall health, different approaches to getting in shape, the real-life struggle of becoming an Instagram fitness influencer, and one couch potato's reluctant journey to getting active.

We think of life and death as clear cut — you're alive or you're not; your heart's beating or it isn't; your brain functions or it doesn't. But when you look a bit deeper, both on a biological level, and in terms of people's experiences, the border where life ends and death begins starts to look less firm, leading to questions about what comes next.

On this episode, we explore the blurred line between life and death. We hear about near-death experiences, and what researchers say about the difference between our brains and our consciousness; we discuss a pioneering approach to collecting organs that is raising questions about the definition of death; and we'll explore why some people experience sudden bursts of lucidity before death. Also, a story about a controversial contest to prove the existence of life after death.

Navigating insurance woes, trouble scheduling appointments, big medical bills — but also broader issues like lack of access, distrust in the medical system, and language barriers can stand in the way of patient care. On this episode, we'll take a look at barriers to health care — especially for America's most vulnerable populations — and explore potential solutions. We hear stories about a new initiative to screen for colorectal cancer, how AI is helping to bridge language divides, and a recent push to institute screenings for the forgotten sense.

What comes to mind when you think of the ocean? Maybe a day at the beach — swimming in the waves, snorkeling through coral reefs, fishing, surfing, and sunsets that kiss the blue horizon. But Earth's oceans are more than all of that; they're our planet's defining feature, its largest ecosystem, the original source of all life, and, according to physicist and oceanographer Helen Czerski, the engine that powers our planet. On this episode, we talk with Czerski about her new book, "The Blue Machine: How the Ocean Works," and why she says the ocean is critical not only to our climate system, but to the big and small processes that sustain and shape life on Earth. She also helps us understand the many intricacies of the sea, from the reasons why it's salty to how the Earth's rotation affects its currents. We also hear stories about efforts to restore coral reefs using sound and find out why scientists are looking for climate time capsules at the bottom of the ocean.

For decades, the idea that you could attack genetic illnesses right at the root — that you could modify people's genes to treat or cure disease — sounded like science fiction. But in recent years, several new gene therapy treatments have been FDA approved, and many others are showing promise in clinical trials. On this episode, we take a look at what's new with gene therapy, what's on the horizon, and the challenges standing in the way. We hear stories about making these treatments more affordable by changing the manufacturing process, what happened when one family tried to enroll their son in a clinical trial under a looming deadline, and one man's DIY approach to curing his own condition. We also chat with a pioneer in the field of gene therapy about sticking with her research during a time when funding dried up and interest in the field had faded.

In March of 2022, the war in Ukraine was weighing heavily on Fabian Falch, a Norwegian tech entrepreneur. The Russian government had started to censor news stories and social media posts about the war, and Falch wondered how Russian citizens would be able to access information, let alone voice criticism. Then he had an idea: to send emails to Russians — millions of them. Eventually, a conflict researcher got involved in this effort and it turned into a real-time study on what works and what doesn't when it comes to shifting people's perspectives.

On this episode, we explore what we have learned about resolving conflict, and how we can better understand each other's perspectives. We'll hear stories about persuasion, connection, and trying to find some middle ground.

Rejection, or even the thought of it, can strike fear into our hearts, and leave a bad taste in our mouths. It often leads to a mix of sadness, shame, anxiety, and anger — along with nagging questions. What's wrong with me? Why did this person not like me? Why didn't I win this award? Why didn't I get the job? But it doesn't have to be that way, and there's a lot we can learn from not making the cut. On this episode, we explore the experience of rejection — what it feels like, how it functions, and the lessons we can draw from it.We'll hear from a fear and anxiety researcher about the evolutionary roots of anxiety — and why asking someone out on a date can feel like a life-or-death situation. Then we'll explore a common experience among people with ADHD, known as rejection sensitive dysphoria (RSD), and hear how one future physician dealt with the worst rejection of her life.

For most of the big moments in life, we have rituals — proposals, weddings, births, graduations, and anniversaries. We know how to talk about them, how to celebrate them, how to honor them. But there's one moment we all face that lots of people don't know how to deal with: dying.

In fact, a majority of Americans avoid end-of-life planning, even though most say it's important. Losing a loved one — not to mention facing your own mortality — is a hard reality to contemplate. So how do we go about having those tough conversations about the end of life? Is there a "right" way to talk about it? Can we really prepare for death and the grief it brings in a way that is helpful? And does it get any easier when people know it's coming?

On this episode, we explore how we talk — or avoid talking about — death; the funny, tender, and hopeful moments that arise in those conversations; and how we can best support our loved ones in their final moments. We hear stories about two very different approaches to confronting death, how death doulas help usher their patients into the unknown, and new approaches to dealing with prolonged grief.

Flying saucers, little green men, and the X-Files — for years, that's what most people associated with unidentified flying objects, or UFOs. They were the stuff of sci-fi and supermarket tabloids, conspiracy theories and punchlines.But ever since a bombshell article in The New York Times several years back documented confirmed sightings by navy pilots, UFOs — or UAPs, unidentified aerial phenomena, as they've been rebranded — have been slowly migrating into the mainstream.Today, it's not uncommon to find scientists, elected officials, and decorated members of the military talking publicly about UFOs. Records are being unclassified, research projects launched — there was even a Congressional hearing dedicated to UFOs. And beneath it all lies the age-old question: Are we alone?On this episode, we explore the past — and future — of the search for life on other planets. We talk with a historian about how attitudes towards UFOs have changed over the decades; we look at how scientists are approaching the study of UFOs; and we hear the strange story of a sighting back in the 90s that begs the question of what — and who — we believe.

Dealing with a serious or chronic health condition is hard enough — but what happens when that condition comes with moral judgment? That's the case for millions of people around the world. From obesity to lung cancer, sexually transmitted diseases to mental illness, stigmatized conditions are shrouded in shame and blame that can not only hinder treatment — but ruin lives.

On this episode, we explore stigmatized health conditions — how they earn their reputations, affect the lives of patients, and complicate efforts to treat them. We hear about the flawed effort to track down the origin of the HIV epidemic in the U.S. that inadvertently introduced a new term into our language. We explore what researchers say is behind the "blame and shame" game in public health, and we find out why a man diagnosed with antisocial personality disorder says his condition isn't always as scary as people think.

Most of us have been there — feeling our jeans get tighter, watching the numbers on the scale creep up, declaring that this time we're going to lose the weight and keep it off.

For a lot of people, though, it seems like no matter what they do — how many diets they try, calories they count, or hours they spend at the gym — losing weight isn't just hard; it feels downright impossible. Two in five American adults are obese, and the numbers keep rising. It's been called a public health crisis, especially since obesity can lead to a number of other health issues, like heart disease and diabetes.

But scientists are learning more about how fat cells function — and how they affect the rest of the body. And new injectable weight loss drugs are giving many people renewed hope.

On this episode, we explore this new science, and how these solutions are — or aren't — working on the ground. A researcher explains what happens on a cellular level when we gain weight, a pediatrician hunts for solutions to help her young patients, and we'll learn about the practical challenges surrounding drugs like Ozempic.

In 1978, NASA recruited six candidates out of thousands of applicants for a special, groundbreaking mission: to become the first American women in space. Over the next few years, the six women would endure sexism, grueling training, and unending scrutiny from the media. In her new book, "The Six: The Untold Story of America's First Women Astronauts," author Loren Grush explores the stories of these female pioneers, along with the longer history of women's fight for inclusion in the male-dominated world of NASA.

On this episode, we talk with Grush about how America's first female astronauts came to be, their journeys and challenges, and what kept them committed to their mission. Later, we hear from another space pioneer — a Navajo NASA engineer who says his childhood in Arizona prepared him for his work studying Mars.

We spend a lot of time thinking about happiness. Wondering if we are truly happy, and how we could get there. We try to predict what will make us happy in the future, or what might lead to misery down the road. We chase success, money, and love. We work hard or maybe move from place to place to find fulfillment. But what actually brings us contentment is often very different from what we thought, and researchers are trying to quantify what leads to that lasting sense of well-being.

On this episode, we'll explore happiness - and how we can find more of it. We'll hear about the longest-running study on the subject, find out if money is really a game-changer, and talk to a therapist who says we need to stop obsessing over happiness.

The teenage years can be an emotional rollercoaster. One moment everything is great, it's amazing, then suddenly life is terrible, and all is ruined. But - it seems like something else is going on right now, beyond these expected ups and downs. Statistics are rising across the board for issues like anxiety and depression, the number of kids receiving mental health treatment, or reporting that they feel hopeless.

So what's happening - and what's to blame? On this episode: teens, their mental health, and how families can navigate these challenging times. We'll hear from psychologists, parents and teens about their approaches and solutions. We'll also visit a gymnasium full of teenagers to hear what they really want to know about mental health, and meet an adolescent who found an unexpected ray of hope in a very dark place.

Over the past few years, remote working has transformed millions of people's lives — giving them more time for family, more control over their schedules, and a better work-life balance. But now, a growing number of companies — including tech giants like Google and Meta — are making their employees return to the office, citing concerns about productivity, innovation, creativity, and employee engagement. But how does working in the office measure up when compared to working remotely? On this episode, we explore the future of remote work, and hear about the latest research on which settings and models are best. When does it pay off to bring workers back, and when is working remotely more fruitful? We hear stories about how digital nomads are reshaping what work looks like — and the places they live; how working from home affects productivity; and how workplace psychologists say office design could lure employees back to the workplace.

Science is all about observing the world. But how do you study something you can't see, smell, or hear — like the tiniest particles all around us? How do you test a new energy source when it doesn't really exist yet? These are the challenges that the world of physics often faces. You can come up with theories, using modeling and calculations, and devise some kind of experiment on paper to investigate things. But then you have to translate those ideas into tangible, real-world experiments, which is often incredibly challenging. On this episode, we peek behind the curtain of multimillion-dollar physics experiments that are changing the way we understand our world — and hear about some of the big challenges they face. We dig into the origins of the James Webb Space Telescope, talk with xkcd cartoonist Randall Munroe about some of his more outlandish — and complicated — physics calculations, and hear from accelerator physicist Suzie Sheehy about the physics experiments that changed the world.

Whether you're a student or a doctor, a plumber or a truck driver, a university lecturer or a radio reporter, artificial intelligence is changing the way we work. For some workers, A.I. is taking over tedious and time-consuming tasks, freeing them up to focus and get more done. For others, it's led to questions about what A.I. means for the future of work — or whether, in a few years, they will have jobs at all. What are the limits of A.I.'s abilities? How can it help us do our jobs better rather than simply replacing us? What checks and balances do we need to control its development? And are there any jobs that will not be affected? On this episode, we explore how A.I. is transforming the way we work — for good and for bad. We hear stories about the future of robot plumbers, the push to integrate A.I. into medical education, how physicians are responding to its increasing presence in medicine, and the dystopian threat of neurotechnology.

It seems like every day, new skin care products hit the market: lotions, serums, collagen boosters, light therapy, at-home lasers — potions and procedures designed to coax our skin into peeling and healing, plumping and renewing. Their promise: wrinkle-free faces, poreless, dewy skin, and an eternally youthful glow.

But there's no one magic bullet to flawless skin. And what is this chase really about?

On this episode, we get into the science of skin care, looking at what works, what doesn't, and what dermatologists have to say about the latest frontiers in our quest for eternal youth. We hear stories about a new treatment that uses stem cells to rejuvenate skin, some shady aspects of the Botox business, and why K-beauty has taken global skin care by storm.

If you've tried to book a doctor's appointment lately, chances are, it's been challenging. Many practices are not taking new patients, or open slots are weeks or months away. For some patients, it has meant gritting their teeth through pain and anxiety.

For others — like people living in rural areas or trying to see in-demand specialists like psychiatrists or neurologists — it can feel almost impossible to get an appointment at all, posing real threats to their health. Medical organizations warn that we're experiencing a physician shortage — and that things will only get worse.

On this episode, we look at this, and other, shortages plaguing the world of medicine, from medications to donated blood. We investigate what's causing this scarcity, and some potential solutions. We'll hear stories about the surprising origin of the physician shortage, and why we still have unemployed MDs sitting at home; what's behind the recent shortages of several high-profile medications; and how researchers are trying to address the chronic shortage of donated blood.

For centuries, writers and philosophers have imagined what a perfect world might look like — if only we had a chance to start over, build it all from scratch. The term "utopia" comes from ancient Greek. It literally means "no place," but it's also a pun on "eutopia," meaning "good place." In other words, it's a good place that doesn't exist. But that hasn't stopped a never-ending stream of dreamers and seekers — from political and economic theorists, to dictators, hippies, and religious zealots — from trying to create utopias of their own.

So, what is it that makes the idea so seductive? Who is attracted to a more perfect world? And what happens when it all goes wrong? On this episode, we explore modern attempts at real-life utopias. We'll hear about an AI researcher's doomed mission to establish a post-apocalyptic community in the Scottish Highlands, what it's like growing up in a utopian community, and the dark side of efforts to build sustainable smart cities around the world.

When you're at the doctor's office or a hospital, it's easy to get frustrated. Why is this taking so long? Why do the nurses look so tired? Why does my doctor seem distracted? Who's making sure my diagnosis is right?

There are people, stories, and entire worlds that could provide answers to these questions — but as patients, we don't get to see them. So, on this episode, we'll take you behind the waiting room doors, to talk about some of the big issues that affect the health care workforce. We'll hear stories about the decades-long fight over residents' work hours, the history of travel nursing, and what two long-time ER nurses have to say about burnout. We'll also meet some of the crucial, but little-known, professionals who work behind the scenes in medicine.

Skydiving, BASE jumping, climbing the highest peaks, adventuring to remote parts of the world — pushing the boundaries of safety. For thrill-seekers, chasing the rush is what it's all about. Where lots of us would break into a cold sweat, they experience something different: calm, focus, even moments of sublime awe. So what is it that makes thrill-seekers different? On this episode, we investigate what fuels their desire for adventure, and ask when the pursuit of kicks becomes dangerous and disruptive. We hear stories about storm chasers, rocket builders, and hikers. We also talk to a psychologist who avoids thrills in his personal life, but is deeply invested in understanding why other people love it.

Freedom sounds great as an idea. Who doesn't want to be free to do what they want? But when you take a closer look, freedom becomes more complicated. What does it really mean to be free — and how free can we be? On this episode, we'll look at freedom from different perspectives. We'll talk with a neuroscientist who says we evolved to have free will — even though it can sometimes feel like our brains are just following a bunch of preset options. And we'll hear from a social psychologist who says that being human means we need other people and living in groups always comes with limitations. We'll also meet a man who relied on a single word to unlock more freedom in his life.

In October of 1947, a navy reserve pilot named George Earle IV received strange orders: He was to pick up several 55-gallon barrels at the Philadelphia Navy Yard, fly out 100 miles southeast of Atlantic City, and then dump them into the ocean — all in secret, in the dead of night. Earle would repeat the mission twice more without ever being told what he was dumping. But he had a clue. Before leaving, scientists would swarm Earle and his cargo using Geiger counters to measure radiation. This told Earle one thing: Whatever he was dumping was radioactive, and probably dangerous. It would be another three decades before Earle revealed the secret missions to the public, and even longer before anyone knew the origins of his cargo. On this episode, we unfold the never-before-told story of Earle and the classified operation that he was a part of and explore the remnants of the atomic age and the waste it has left behind. We hear about the most powerful nuclear weapon ever detonated by the U.S. — and the devastation it wrought on a tiny island country; the Navajo people's fight to seal hundreds of uranium mines scarring their land; why nuclear power plants need a new solution to house their waste; and why the future of nuclear energy could look very different.

It's a simple question with lots of answers: Who are you? You might answer with your name, age, gender, or race. Or you might define yourself by your family — as a sibling, a parent, or son or daughter. You might choose your profession, your passion, your culture, or values. We hear a lot about embracing our "true selves" — the essential core of our beings; the thing that makes us us. But when you break it down, what is the self? Where does it come from? On this episode, we talk to social psychologist Brian Lowery about his new book "Selfless: The Social Creation of 'You.'" He argues that our sense of self mostly comes from other people, and from cultural and societal context. We'll also hear the story of a young woman whose sense of self was destroyed by a traumatic brain injury — and what the healing process revealed about the forces that determine our path in life.

The messages we receive around quitting are usually straightforward — don't do it. It's something we hear everywhere — from greats like Michael Jordan and Wayne Gretzky, in movies and TV shows, on motivational posters and in children's books: Go the distance. Never give up. Quitters never win, and winners never quit. But what if giving up really is the best option? What if we're miserable, or burned out, or realize our goals have changed? When should we stick it out — and when should we walk away? On this episode, we explore those questions with writer Julia Keller, who examines the science — and potential benefits — of throwing in the towel in her new book, "Quitting: A Life Strategy: The Myth of Perseverance and How the New Science of Giving Up Can Set You Free." We also hear stories about one woman's reckoning with the effects of long COVID on her life, and what prompted a young 20-something to give up everything for a life on the road.

Humans have long been fascinated by the idea of communicating with other species — not just teaching animals to mimic human words, but truly understanding their calls or cries, and interpreting their meaning. In recent years, new technologies and research are getting us closer to that point. So what are scientists learning about the way animals' minds work — what they think about, care about, and want us to understand? On this episode, we explore animal communication — from their ability to speak our language, to our ability to understand theirs. We hear stories about what viral videos of "talking" dogs and cats are teaching scientists, the hidden meanings behind whale songs and dolphin whistles, and how machine learning is decoding the oinks and squeals of pigs.

We all know how stress — or anger, or pangs of anxiety — can affect the body. Your heart rate increases; your blood pressure rises; maybe your palms feel sweaty, or your stomach feels tight. Likewise, our bodies have a profound impact on our minds. When we experience pleasure, happy chemicals flood our brains, keeping us calm and relaxed. Chronic pain, on the other hand, can cause anxiety, depression — even problems with memory and focus. The mind and body form a powerful feedback loop — with each triggering processes in the other. But in medicine, there is still a firm line separating physical symptoms from thoughts and emotions, a barrier between physical and mental health. Increasingly, though, researchers are challenging that disconnect, and new treatments are exploring surprising ways in which the body helps heal the mind, and vice versa. On this episode, we explore the mind-body connection. We'll hear stories about how meditation is being used to treat long COVID, the burgeoning field of cardiac psychology, and harnessing our fight-or-flight response to treat PTSD.

More than a third of Americans use complementary and alternative medicine, ranging from acupuncture to herbalism, Ayurveda to homeopathy. But despite its growing popularity, complementary and alternative medicine remains, for the most part, outside the Western medical mainstream — regarded by some as fringe, and by others as straight-up quackery. Despite that, many researchers and supporters have been trying to gain a deeper understanding of medical practices from around the world, and to incorporate them into our health care system. And that's led to more questions: Which practices work, and for what conditions? How do they work? And how do we measure and standardize treatments when they're removed from their cultural contexts? On this episode, we step outside the boundaries of Western medicine to explore those questions. We hear stories about a mysterious Vodou treatment, the struggle to bring acupuncture into the medical mainstream, and answers to Western skeptics.

Sleep — we all need it, but most people aren't getting enough of it. Ideally, we spend about a third of our lives asleep. When we're well rested, we feel like we can take on the world. But when we're not, we find ourselves exhausted, cranky, moody, forgetful ... and our overall health takes a hit. Clearly, sleep is important. The question is — why? What happens when we sleep? What makes it such an important part of our survival? And what's stopping us from getting our best rest? On this episode, we look at the anatomy of sleep — why it matters, how we get our best sleep, and what happens when we don't. We hear stories about what happened to one physician when long COVID brought her sleeplessness to a crisis level, why one physical therapist says we're all sleeping wrong, and a look inside our sleeping brains.

Not only that, our brains make sense of it all, allowing us to learn, work, form relationships, and navigate the world. On this episode, we take a closer look at how this all works — and why it sometimes doesn't. We hear stories about listening instead of reading — and test the limits of speed listening; we'll find out why reading comprehension tests in schools may be misguided; and why some people who think they're hard of hearing might actually have a different issue going on.

If you look around for Mother's Day gifts, you'll probably see stuff like bubble baths, spa days, yoga classes — a whole slew of things aimed at promoting "self-care" for tireless (but actually exhausted) moms. But for a lot of overwhelmed mothers, self-care becomes just another box to tick — another item on an endless to-do list that never gets finished. The demands of modern motherhood can be overwhelming: Moms are expected to do it all and do it perfectly — even if that means compromising their own well-being. On this episode, we talk about the challenges of motherhood, and how moms can find the space and time to take care of themselves. We talk with a perinatal psychiatrist about the contradictory demands of motherhood, and why bubble baths aren't the answer; hear about an initiative to help mothers dealing with postpartum depression; and learn about the unexpected ways that motherhood changes the brain.

Rejection, or even the thought of it, can strike fear into our hearts, and leave a bad taste in our mouths. It often leads to a mix of sadness, shame, anxiety, and anger — along with nagging questions. What's wrong with me? Why did this person not like me? Why didn't I win this award? Why didn't I get the job? But it doesn't have to be that way, and there's a lot we can learn from not making the cut. On this episode, we explore the experience of rejection — what it feels like, how it functions, and the lessons we can draw from it. We'll hear from a fear and anxiety researcher about the evolutionary roots of anxiety — and why asking someone out on a date can feel like a life-or-death situation. Then we'll explore a common experience among people with ADHD, known as rejection sensitive dysphoria (RSD), and hear how one future physician dealt with the worst rejection of her life.

There are constant rebuttals that arise in our minds: We're too busy. We're too tired. We need a break — we'll start next week. At the same time, we're bombarded by messages from people who are all about fitness — influencers with seemingly perfect bodies and a healthy glow, who convince us that we too can get into shape. It's a habit that many of us try to cultivate — yet often seem to hit a wall. On this episode, we look at the science of fitness, the evolution of cultural messages surrounding exercise, and how we can overcome inertia to start fitting it into our lives. We'll hear about how exercise affects our mood and overall health, different approaches to getting in shape, the real-life struggle of becoming an Instagram fitness influencer, and one couch potato's reluctant journey to getting active.

On April 3, 1973, an engineer named Martin Cooper stood nervously along a busy midtown Manhattan street, about to make a phone call. It was a call that would change life as we know it: The first cell phone call ever. The phone Cooper used that day — a prototype — was a bulky, 2-pound monster that looked a bit like a shoe with an antenna sticking out of the top. In the half-a-century since, this technology has changed more about the way we communicate and connect than Cooper could've ever imagined. On this episode, we mark the 50th anniversary of the first cell call with an exploration of the past, present, and future of mobile communications.

Pain is powerful — and when it becomes chronic, it can be all-consuming. It takes over our minds, saps our energy, and becomes the focus of our existence. And yet, pain is also invisible. We can try to describe it — stabbing, nagging, dull, achy; we can rate it on a number scale from one to 10, or point to a smiley or frowny face to define it, but it's not something we can ever fully communicate. Our pain is ours — to feel, to bear, to live with. Millions of Americans live with chronic pain, and yet it can be a profoundly lonely experience. The individual nature of pain, the mysterious way it often sneaks into our lives, without a definitive source, can make it hard to deal with — and even harder to treat. On this episode, we explore the nature of chronic pain — what causes it, how it affects us, and the ongoing fight to stop it. We talk with physician Haider Warraich, who wants to change the way medicine thinks about pain, people who've spent years trying to treat their pain, and a reporter who's tracking the newest developments in pain medicine.

It's the goosebumps you get at the crescendo of your favorite song; the stupefying wonder that comes with witnessing a birth or a death; the astonishing mystery we feel when gazing at the vast night sky. This is awe — a complex, often overwhelming emotion that can elicit everything from pleasure and connectedness to a crawling sense of uncertainty. Moments of awe can create unforgettable memories — and they can have a lasting impact on our minds and the way we interact with others. One of the leading scientists studying awe is Dacher Keltner, a University of California, Berkeley psychologist, who's dedicated the past 15 years to investigating the origins and effects of this emotion. On this episode, we talk with Keltner about his new book "Awe: The New Science of Everyday Wonder and How it Can Transform Your Life." He discusses his own, very personal experience of awe amid profound grief, the ability of awe to transform our experience of the world, and how we can cultivate awe on a daily basis. We also hear from listeners about their experiences of awe, and listen back to a story about how voyages to space change the way astronauts perceive life, their relationships, and Earth as a whole.

The death of a loved one can be shattering — especially when it's unexpected. It destroys our feeling of safety, warps our sense of reality, and often leaves us feeling lost ... unsure if we'll ever come out on the other side. It's an experience just about everyone goes through at some point in their lives, and yet it can feel profoundly lonely. There's no linear logic or prescribed progression; grief advances stubbornly at its own pace. The wounds can feel both fresh and ancient, stifling and endless, like it's a connection to our loved ones — and a wall that we can never break through. And yet, every day, people do survive their grief — they live with it and through it, and emerge on the other side. On this episode, we hear stories of grief and healing. A mother whose son was murdered at the Sandy Hook shooting in 2012 describes how her grief has changed over the past decade. We will also explore what researchers have learned about grief in the wake of the pandemic — what some have called a "shadow pandemic" of loss. And we'll meet a researcher who is trying to compile the best information to help people who are dealing with grief.

It's that time of year when we celebrate something we usually hate: fear. We visit haunted houses and corn mazes or binge-watch the scariest horror movies. But our relationship with fear is complicated. In its most primitive form, fear is about survival — it raises our heart rates, redirects our blood flow, makes us faster and fiercer, all so we can face — or escape — serious threats. In other settings — where there's no real danger — fear can feel exhilarating, fun, and exciting. It can serve as a form of entertainment, or even help us focus and perform better. On this episode, we look at fear and how it overlaps with other emotions. We hear stories about why we love scary movies, overcoming paralyzing stage fright, and what happened to one man who completely lost his sense of fear.

The modern ICU, or Intensive Care Unit, was born out of a time of crisis. It was 1952, and polio was raging in many places — especially the city of Copenhagen. Patients poured into the hospitals, many of them gasping for air, turning blue, and eventually dying. Then a brilliant doctor tried a radically different approach — pumping air directly into patients' lungs. It was an idea that would require intensive manpower, but save many lives. And it led to the birth of a new kind of medicine: intensive care. Seventy years later, ICUs sit at the cutting edge of modern medicine. They're the destination for the sickest patients — including those who're hovering at death's door — and home to some of medicine's most profound interventions. ICUs can be a place of pain and healing, of comfort and dying, a laboratory for innovation, or a sanctuary for grieving families. On this episode, we take a look at intensive care — its roots, what it's like to work there, and how the coronavirus pandemic has changed it.
