What followed was a harrowing journey she was not prepared for. On this episode, what people should consider before quitting. We also explore whether new tools could help doctors better match patients with medications.…
In some ways, our imagination is like an all-access pass. It can transport us to a different place, it allows us to picture a beautiful beach, or a lush flower garden. We can envision what our lives may look like in the future or revisit the past. Psychologist Cassandra Vieten argues that using our imagination is not about immersing ourselves in a fantasy world. It’s a powerful tool that affects…
We tend to think that creativity flourishes in the absence of limits, when we have all of the freedom to innovate and dream big. But what if the opposite is true? What if constraints — from strict rules to tight deadlines — actually make us more creative? On this episode, we explore how limitations force us to think differently, solve problems in unexpected ways, and allow us to create our best…
Millions of people in the U.S. have chronic pain that’s unresponsive to medical interventions. But there are new and comprehensive ways of treating pain. We explore how emotions, stress, sleep, and diet impact pain, a new option for easing labor pain, and emerging research that could reduce the addictive properties of opioids. We often think of pain as a physical ailment — but newer research shows…
Vacations are a time to experience new things, and restore our minds and bodies — but sometimes the opposite happens. On this episode, when vacations wreck your health — and how to deal. We hear about evidence-based ways of overcoming jet lag, tips for avoiding "vacation constipation,” surviving the cruise from hell, and what's behind snorkeling deaths in Hawaii. SHOW NOTES: We hear from listeners…
Investigators have long relied on science to help solve crimes, from fingerprint and blood splatter analysis to the psychology of criminal minds. But not every investigative technique rests on solid scientific ground. On this episode, how science is used in criminal investigations, and what happens when these methods aren’t as reliable as we might think. For years in Hollywood, a kind of mythology…
When twin brothers Trevor and Kyle Ritland were children, their father — a biologist — would tell them stories about a mythical creature that lived high in the misty mountains of Costa Rica: the golden toad. The toad was elusive, he told them — but for a few weeks every spring, hundreds of them would emerge from the shadows to mate, lighting up the dense forest like brilliant spots of fire. Until…
At the best of times, alcohol makes us feel great — relaxed and gregarious, warm and fuzzy, happy and confident. But at the worst of times, it can morph into a serious problem, damaging our relationships, our health, and our lives as a whole. On this encore episode, we explore our relationship with alcohol. Why we consume it, how it affects us, and when it’s time to quit. We talk with surgeon and…
Two hundred and fifty years ago, Philadelphia was not just the center of political revolution, but a hub of scientific discovery. For America’s founders, science was more than a pastime — it was a way of understanding the world and the natural laws that shaped it. On this episode, we explore how science and innovation helped give birth to a new nation. We visit the American Philosophical Society…
On this episode, we explore the lingering effects of medical crises, both physical and emotional, and what true healing really means. We hear about one doctor’s journey to reconnecting with her body — and her pain — after nearly dying, what researchers are learning about medical trauma, and how a traumatic brain injury transformed the lives and marriage of a couple. As a physician, Rana Awdish’s…
We often talk about the biological and emotional transformation of motherhood, but what happens to men’s brains when they become fathers? On this episode, host Maiken Scott chats with psychologist and researcher Darby Saxbe to explore her new book, “Dad Brain: The New Science of Fatherhood and How It Shapes Men’s Lives.” While the "dad bod" is a common trope, Saxbe’s research reveals that the…
Music can transport us to a different time and place — but how does that happen? We explore how music affects our brains — from its ability to tap into our memories and imaginations, to “musical daydreaming” and how it helps us understand both the world and ourselves. We also discuss the therapeutic power of music. We talk with Elizabeth Margulis, director of the Music Cognition Lab at Princeton…
On this episode, we look at the intersection of health, medicine, and the law. We explore how the upcoming rescheduling of marijuana may impact research on the drug, hear the story of a doctor who faced manslaughter charges in the 1970s for providing an abortion, and learn about legislation that some states are using to try and keep private equity out of medicine. Near the end of 2025, President…
Think about the last time you were really happy — where were you? What were you doing? Who were you with? And, most importantly, how can you recreate that feeling? Happiness can feel like lightning in a bottle — beautiful in the moment, but hard to find and harder yet to sustain. So what is it that makes for a happy life? And how do we engineer our lives for greater contentment, fulfillment, and…
On this episode, we explore the world of color — from how we perceive it, to our efforts to describe and differentiate its many shades. We talk with a lexicographer about efforts to standardize synthetic colors, and how we describe them, and investigate how we know that the colors we see are the same as the ones everyone else sees. The Pulse host Maiken Scott adds some pops of color to her…
When disaster strikes and the chips are down, who makes it out alive? On this episode, we explore what it takes to survive a crisis. We hear the incredible story of a 17-year-old girl, who after surviving a plane crash, faced a harrowing journey though the Amazon to safety, why some people experience hallucinations when facing death, and how we’re wired to behave in emergencies. On Christmas…
How do you sum up the experience of motherhood, and all of the changes it brings, both big and small? It’s a transformation that affects everything — hormones, body image, relationships, feelings, money, career — even the answers to larger, existential questions like, “Who am I in this world, and what is my role?” On this episode, we explore the impact of motherhood. We talk with a psychologist…
For decades, psychedelics like LSD, psilocybin, and MDMA were regarded as dangerous drugs of abuse — but that’s started changing as research increasingly reveals their ability to help treat serious mental health issues. On this episode, we listen back to past conversations about the science behind these drugs’ therapeutic potential, along with powerful stories of healing. When Marcus Capone…
Forty years ago, news was only beginning to emerge that an accident had occurred — one that could put millions of people at risk. A reactor at Chernobyl Nuclear Power Plant, then part of the Soviet Union, had exploded, releasing a plume of radioactive gases and particles into the atmosphere and spreading some of the most hazardous radionuclides known to humanity. We look back at what caused this…
Science writer Michaeleen Doucleff was sitting on a beautiful beach with her daughter, but she couldn’t relax. She kept reaching for her phone, checking it over and over. She was frustrated but couldn’t stop. Why was she doing this? In her new book, “Dopamine Kids: A Science-Based Plan to Rewire Your Child's Brain and Take Back Your Family in the Age of Screens and Ultraprocessed Foods,” Doucleff…
Politicians are eyeing Greenland as an important strategic location, perfectly situated between Europe and North America. President Donald Trump has said he remains highly interested in acquiring or controlling Greenland as a national security and economic asset. But for a lot of researchers, Greenland is a beautiful and fragile place that holds important clues to the Earth’s past and future. So…
The number of urgent care centers in the U.S. has doubled over the past decade, and it isn’t hard to see why — they fill a void in the market. Urgent care offers quick and convenient access to medical care when patients can’t get an appointment to see their primary care doctor, but their issue doesn’t seem to warrant an ER visit. But the rapid rise of urgent care has come with some growing pains —…
Have you ever looked in the toilet bowl and wondered, ‘Is that normal?’ Well, you’re not alone — and according to neurogastroenterologist Trisha Pasricha, it’s time to talk about poop. Pasricha says understanding what’s normal about your bowel movements isn’t just a silly or squeamish conversation, but one that can be lifesaving. Digestive issues affect millions of Americans, yet many of them are…
We often think of perfectionism as a virtue; a kind of shorthand for high standards, a solid work ethic, and attention to detail. But in reality, perfectionism can be a paralyzing force — like sand wedged in the gears of our minds. It slows us down, makes us question our choices, and traps us in an endless cycle of tweaking and re-tweaking, unable to move on to the next task. It can even have…
From Kevlar to windshield wipers, pulsars to dark matter and radioactivity, women are responsible for countless scientific discoveries and inventions that changed the world — and yet, many of them remain overlooked, forgotten, or ignored. On this episode, we shine a light on some of these women and hear about the detective work required to unearth their lives and legacies; chasing clues, rifling…
Over 60 million Americans — or one in four adults — currently serve as family caregivers for partners, parents, or other loved ones with illness or disability. But despite how common this experience is, it can often feel extremely isolating for the caregiver. In between daily tasks like wound care, medications, and bathing, or navigating health care and insurance — many caregivers find themselves…
The signs are all there — the perfectly packed gym bag is collecting dust in your closet, the kitchen pantry has quietly been refilled with junk food, and your early morning alarms are losing their battle with the snooze button. The goals you set at the beginning of the year seem more and more unattainable. It may feel like you don’t have enough determination — enough resolve — but productivity…
When Alexander Graham Bell made the first-ever phone call on March 10, 1876, he never could have dreamed how the telephone would evolve — not to mention the many ways it would end up changing the way we live, work, and communicate. This week, on the 150th anniversary of that first call, we take a look back at the history of the phone, and how it transformed America. We hear about the dramatic race…
Do animals feel love, anger, or empathy? Researchers have long dismissed such ideas as anthropomorphism, arguing that attributing human emotions to animals was unscientific. But as we learn more about animal sentience, that’s starting to change — and, in the process, we’re learning more than ever about the complex inner lives of animals, including why we may be more alike than we once thought. On…
When someone wrongs us, getting revenge can feel like the only right move — the only way for us to balance the scales, to set the world right again. But the consequences can be disastrous, especially when payback becomes an all-consuming obsession. On this encore episode, we talk with lawyer-turned-researcher James Kimmel about his book, “The Science of Revenge: Understanding the World’s Deadliest…
Artificial Intelligence is already guiding surgeons in operating rooms; it’s used to read image scans or take notes during your doctor’s visit. And the pace of AI integration is only getting faster. So what will health care look like in the next 10 to 20 years? Will we consult with an AI-powered doctor before we see our primary care physician or a specialist? Will it give more patients access to…
For those deep in the dating trenches, love and attraction can feel like uncrackable riddles. How do I make myself attractive to others? How do you know if someone’s into you? What should I look for in a partner — and how do I know if I’ve found “the one”? On this episode, we train a scientific lens on the mysteries of love. We talk with psychologist Paul Eastwick about the latest research on…
When it comes to serious health issues like obesity, heart disease, and cancer, Black Americans have higher rates and worse outcomes than most other groups in the U.S. It’s a problem that’s gained growing attention over the past few decades, as public health experts have worked to untangle the causes of these disparities, and to find ways of mitigating their effects. Now those efforts face serious…
At the best of times, alcohol makes us feel great — relaxed and gregarious, warm and fuzzy, happy and confident. But at the worst of times, it can morph into a serious problem, damaging our relationships, our health, and our lives as a whole. As we close out Dry January, a popular movement to abstain from drinking for a month, we explore our relationship with alcohol. Why we consume it, how it…
On January 28, 1986, a frigid cold day with an icy blue sky, the Space Shuttle Challenger exploded just 73 seconds after launching from Cape Canaveral, Florida. The accident killed all seven crew members aboard and was the first fatal in-flight spacecraft disaster in NASA's history. For many, the explosion came as an absolute shock. Millions of people were watching live, including school children…
Space exploration relies heavily on the interest of the public — the voters, and taxpayers, who are ultimately footing the bill. But that support and excitement can be fickle. When space missions go well, and deliver new insights, the payoff is cheering crowds and increased support. But when they don’t, the result can be reduced funding, canceled missions — and even deaths. That means, with each…
If you go by pop culture depictions, menopause seems like no big deal — a few hot flashes, some comical bouts of hormone-fueled rage, and the “big change,” as it was once called, is over. But for many of the 2 million American women who enter menopause each year, the symptoms can be a lot more serious and long-lasting, ranging from vertigo and joint pain to brain fog and heart problems. On this…
Capsule wardrobes have become a popular way to streamline and organize your closet — basically, paring it down to a few staple pieces that you can combine in multiple ways, and freshen up with seasonal accessories. Registered Dietitian Jenn Salib Huber says this is how women should think about nutrition during perimenopause and menopause. Rather than obsessing over calorie counts and…
Think about the last time you were really happy — where were you? What were you doing? Who were you with? And, most importantly, how can you recreate that feeling? Happiness can feel like lightning in a bottle — beautiful in the moment, but hard to find and harder yet to sustain. So what is it that makes for a happy life? And how do we engineer our lives for greater contentment, fulfillment, and…
For a lot of us, noise is a constant factor — an inescapable soundtrack playing on loop in the background. Kids screaming, sirens blaring, the roar of traffic, the sounds of music, lawn mowers, construction, and so much more. We ignore it when we can, or wear headphones to block out the racket. But all that noise can actually damage our hearing and, subsequently, our overall health. On this encore…
Twenty-five years ago, President Bill Clinton stood before a podium in the East Room of the White House, and, in front of an all-star lineup of researchers and dignitaries, made a historic announcement: After years of painstaking work, scientists had created “the most important, most wondrous map ever produced by humankind” — the first-ever survey of the human genome. In his remarks, Clinton…
As patients, we often wonder what our role should be when it comes to getting better. Should we research options, get second opinions, and ask lots of questions? Or should we sit back, and let the health care professionals take charge? When does it make sense to push, and when is it best to do less? On this episode, we examine our role as patients, the choices we make, and charting our path toward…
In 1973, Stanford psychologist David Rosenhan published a bombshell paper called “On Being Sane in Insane Places.” In the paper, Rosenhan described faking symptoms to be admitted to a psychiatric hospital, and recruiting several other pseudo patients to do the same. Could staff tell they were faking? What was it like to be a patient in an institution? The “Rosenhan experiment,” as it came to be…
Over the course of 20 years, writer Neil Shea explored the awe-inspiring landscape of the Arctic. He saw narwhals poking their tusks above the water, herds of caribou moving across the tundra, and majestic white wolves raising their young. He documents this fragile beauty in his new book, “ Frostlines .” We talk to Shea about his adventures, and how climate change is transforming the region.
So often, our relationships take a backseat to everything else on our to-do lists — but new research shows that nurturing personal connections plays a central role in our health and well-being. On this episode, we explore the science of connection, from why it’s important, to how we can make it a priority in our lives.
Ahead of Thanksgiving, we do a deep dive into what we actually know about diet, and what we should and shouldn’t be eating. We talk with a nutrition and metabolism scientist about recent diet trends and how they affect our health, hear from several chefs about how they balance nutrition and taste, and find out how the avian flu outbreak could be affecting this year’s turkeys.
How do our dreams connect to health, and how could “dream engineering” help people get over nightmares? Researcher Michelle Carr writes about that in her new book “Nightmare Obscura: A Dream Engineer's Guide Through the Sleeping Mind.” We talk with Carr about why we dream, the benefits of lucid dreaming, and what she’s learning about our ability to “engineer” our dreams.
Chatbots don’t have feelings of their own, but they’ve been stirring plenty of emotions in us humans. On this episode, we explore how AI is making us feel, and what those feelings say about us. We hear about using ChatGPT for DIY therapy, what kinds of personalities we prefer in our chatbots, and how both the market and online culture is responding to the spike in AI-generated content.
On this Veterans Day episode, we explore the invisible wounds of war — and the different paths veterans take to heal them. We talk with a Marine Corps vet about how ceramics helped him reconnect with civilian life, a retired Navy SEAL about his experience with psychedelic-assisted therapy, and a Vietnam vet who, decades after the war, found peace in an unexpected place.
Cybercrime has been around for as long as computers have — but over the past 20 years, it's exploded into a global threat, with staggering financial, political, and even personal consequences. On this encore episode, we hear about the virus that ushered in the age of social engineering attacks, the history of cybercrime, and what led one man to become a hacker.
