We hear about the big picture of climate change almost every day — the threats it poses, the effects on our world and lives, the fight to stop it. Across the world, armies of researchers are contributing pieces to that big picture narrative every day. They often travel long distances and brave the elements to collect information, one small data point at a time. How do Antarctic penguins fare when warming temperatures bring changing conditions to a part of the continent? How do we really know what Earth's climate was like in the past, and how it compares to today? What's it like to spend months living on an old oil drilling ship, in search of tiny ancient fossils? On this episode, we go behind the headlines to spend time with scientists on the front lines of climate research. We'll hear how they're collecting data, what they're learning, and what keeps them motivated. We hear about climate change almost every day — the threats it poses, the fight to stop it.

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. We hear about Cooper's work on this world-altering invention, one community's fight against the 5G revolution, and why satellite phones are making a comeback in a big way.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Health disparities between Black and white Americans run deep in the U.S. Black people are more likely to suffer from chronic conditions like diabetes, hypertension, heart disease, or asthma, and their life expectancy is shorter than that of their white peers. The causes for these inequities are far-reaching and include bias and systemic racism in health care and medical treatments, lack of access to care, and economic differences. Advocates, researchers, and health systems have been looking for ways to address these issues — chipping away at different aspects of the problem. On this episode, we'll look at several different solutions — and meet the people who are pushing for more equitable health care for all.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Finding the right therapist — or, sometimes, any therapist — can be a grueling process. Someone with the right expertise, who is still taking new clients, lives in your area, who accepts your insurance, or whose services you can afford. Over the past few years, online therapy platforms like BetterHelp and Talkspace have seen an explosion in popularity. They promise easy access — anytime you need it — and affordability. Major changes are happening in the field of mental health, as more people turn to online services — not just for counseling, but for diagnosis and prescriptions. How good are these platforms really — for clients and for therapists? And what are the larger issues they raise about the field as a whole? On this episode, we look at the rise of online mental health services. We hear stories about working for one of these apps, what clients like or dislike about them, and the unregulated world of online ADHD diagnosis.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

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.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
