Something You Should Know

The human body is full of strange, ingenious, and often overlooked features that keep us alive every second of every day. And some of the most fascinating parts are the ones we rarely think about — until something goes wrong. Dr. Jonathan Reisman takes us on an unusual tour inside the human body to reveal what our organs, tissues, and bodily fluids can teach us about how we work. He explains why certain parts of the body are far more remarkable than they appear, what doctors can learn from the substances our bodies produce, and why understanding anatomy can change the way you think about your own body. And yes, you’ll also hear why, of all the bodily fluids to choose from, urine is his favorite. Jonathan Reisman is a physician specializing in internal medicine and pediatrics and author of The Unseen Body: A Doctor’s Journey Through the Hidden Wonders of Human Anatomy (https://amzn.to/37vUz8u).

There is actually a name for it, and a reason it feels so incredibly good. Listen and discover what your body is accomplishing when you do it. https://health.clevelandclinic.org/why-does-pandiculation-feel-so-good Something startling is happening between young men and women.

You have seen a dollar bill hundreds of times, but have you ever really studied it? It’s fascinating. And the number 13 plays a prominent role. This episode begins with a short tour of a U.S. $1 bill. https://www.niehs.nih.gov/health/kids/games/riddles/jokes/dollar-bill-trivia You spend a lot of time with clothes – wearing them, buying them, and washing them. How you care for your clothes is important. If you care for them the right way, they will last a lot longer and look a lot better. You will also probably save yourself a lot of time and money. Joining me to explain the right and wrong ways to care for clothes is Zach Pozniak. He is a fourth-generation fabric-care expert and dry cleaner.

There are some questions about the universe that are almost too big to wrap your head around. Why are we here? How did everything begin? Are we alone — or is there intelligent life somewhere else? Could aliens already know about us? And if the universe had a beginning, how does this whole thing eventually end? In this episode, astrophysicist Neil deGrasse Tyson tackles some of the most fascinating mysteries of the cosmos and separates what scientists actually know from what remains speculation. He explains what we know about our place in the universe, the chances that life exists elsewhere, what an encounter with extraterrestrial intelligence might look like, and what science predicts about the ultimate fate of the universe. Along the way, Neil offers the kind of perspective that comes from thinking on a cosmic scale — where Earth is just one tiny place in an unimaginably enormous universe and some of our biggest questions still don't have definitive answers. It’s a fascinating conversation about what we…

What are spiders doing inside your home? You’ve probably spotted a few crawling around, especially in the fall. But contrary to what you might assume, many of those spiders didn’t just wander in from outdoors. And there’s a very specific reason you suddenly start seeing more of them this time of year — it has a lot to do with romance. https://www.burkemuseum.org/collections-and-research/biology/arachnology-and-entomology/spider-myths/myth-spiders-come-indoors Should you say something — or just keep your mouth shut? It’s a dilemma we face all the time. Do you tell someone they have something stuck in their teeth? Should you ask a stranger who is crying if they’re okay? What about telling a friend what you really think about the person they’re dating? It turns out we’re surprisingly bad at predicting how people will react when we speak up — or how they’ll feel when we don’t. Vanessa Bohns joins me with fascinating research that can help you handle these awkward everyday moments much better. She is a social…

Groceries are expensive, but there is a surprisingly simple way to leave the supermarket with a smaller bill — and it has less to do with what you buy than how you shop. I begin this episode with a technique that could help you spend less every time you go to the grocery store.

You’ve probably seen the warning on your passenger-side car mirror: “Objects in mirror are closer than they appear.” Which raises an obvious question: Why put a mirror on your car that deliberately distorts reality? Turns out there is a very good reason—and that distortion may actually help keep you safe. https://science.howstuffworks.com/innovation/science-questions/why-objects-in-mirror-closer-than-they-appear.htm We hear all the time that the world has become a riskier place and that the smart thing to do is play it safe. But is that really true? And what do you give up when avoiding risk becomes your default? Economist Allison Schrager explains why younger people appear more risk-averse than previous generations, why safety has a price, and how to tell the difference between a foolish gamble and a risk actually worth taking.

Who doesn’t like a bit of juicy gossip? We tend to think gossip is petty, mean or something we probably shouldn’t be doing. Yet practically everyone gossips—and it turns out there are some very good reasons why. Gossip actually serves several useful purposes in our personal and professional lives. It can help us figure out whom to trust, learn what’s going on within a group and warn us about people we might want to steer clear of. So why does gossip have such a bad reputation? When does it turn nasty? And is there a right way to gossip? Frank McAndrew is one of the leading researchers on the psychology of gossip. He joins me to explain why we gossip, why most gossip isn’t nearly as bad as we think, and how to gossip well. Frank is Professor of Psychology at Knox College in Illinois.

When someone gets a nosebleed, what are you supposed to do? Many of us learned that you should tilt your head back. That’s not a good idea. There are a couple of key actions to take when your nose bleeds that many people don’t know or don’t do. https://www.mayoclinic.org/first-aid/first-aid-nosebleeds/basics/art-20056683 It’s easy to dismiss optimism as hoping for the best or always looking for the bright side. Yet, true optimism is so much more than that once you understand it. And adopting an optimistic mindset has been proven to make people happier, improve health and longevity and a host of other benefits.

Someone says nine wonderful things about you and one negative thing. Which one are you still thinking about hours later? Probably the negative one. Bad experiences, criticism and unpleasant news seem to have more power over us than equally good things. And it turns out there is a reason for that. Psychologists call it the negativity effect — our tendency to give more weight and attention to what goes wrong than to what goes right. It influences what we remember, the risks we take, the decisions we make and even how we judge other people. We will often work harder to avoid something bad than we will to gain something equally good. John Tierney has researched this phenomenon and explains why negativity has such a powerful hold on us — and, more importantly, what we can do about it. John is a journalist and co-author of The Power of Bad: How the Negativity Effect Rules Us and How We Can Rule It (https://amzn.to/30Gn3EQ).

Why does time seem to move faster and faster the older you get? Summers that once felt endless suddenly seem to disappear in a flash. There are some intriguing theories about why our perception of time changes — and what may actually slow it down. Your brain is constantly interpreting the world, making predictions and influencing what you think and do — usually without you realizing it. That helps explain some surprisingly common quirks of human behavior. Why do we tend to believe we have more control over events than we really do? Why are we so easily influenced by advertising even when we know exactly what advertisers are trying to accomplish? And why does your sense of time change so dramatically over the course of your life? Here to explore these and other fascinating questions about how your mind works is Art Markman, professor of psychology and marketing at the University of Texas at Austin.

Why do you believe some people almost immediately, while others make you skeptical? You might assume credibility comes down to expertise, experience and having the facts on your side. But there is much more going on. Research shows that we respond to subtle signals that can make someone seem more believable — sometimes before we’ve really considered what they’re saying. Even more surprising, some of the things people do to appear credible can actually make them less convincing. And many of the signals that influence us have little to do with the actual message. Understanding this matters more than ever. Every day we have to decide which experts, politicians, salespeople, coworkers, influencers and strangers we should believe — and which ones we shouldn’t.

And it works surprisingly well. https://news.stanford.edu/stories/2014/04/walking-vs-sitting-042414 Can you actually think yourself sick? Absolutely. It’s called the nocebo effect — essentially the evil twin of the placebo effect. If a doctor warns you that a medication might cause certain side effects, simply hearing that can make those symptoms more likely to occur. The same thing can happen when you read about an illness or medication online. Your expectations can trigger very real physical symptoms.

Processed food has gotten a pretty terrible reputation. We’re warned to avoid foods with long ingredient lists, mysterious additives and chemical names we can’t pronounce. “Ultra-processed” has practically become another way of saying “bad for you.” But is that a useful way to judge what we eat? After all, almost everything we eat has been processed in some way, and everything we eat — including perfectly natural food — is made of chemicals. So how can you tell which ingredients are worth worrying about and which ones just sound scary? Why do manufacturers put preservatives, emulsifiers, artificial flavors, stabilizers and other additives into food in the first place? And does a complicated-looking ingredient label actually tell you much about whether a food is healthy? Here to sort through the chemistry is George Zaidan, an MIT-trained chemist who created National Geographic’s web series Ingredients: The Stuff Inside Your Stuff. He is also author of Ingredients: The Strange Chemistry of What We Put in Us…

You probably know that light, noise, temperature and stress can all interfere with your sleep. But what about the moon? Strange as it sounds, some research suggests people really do sleep differently around the time of a full moon — even when they aren’t outside looking at it. So what could possibly explain that? Listen as I reveal what researchers have discovered. https://www.self.com/story/full-moon-sleep Most of us know instinctively that music can change how we feel. The right song can calm you down, lift your mood or bring back a memory in an instant. But scientists are discovering that music may do considerably more than that.

Probably not as often as you could. It is usually easier to look at your phone, avoid eye contact and keep to yourself. Yet those little interactions you have with a cashier, a neighbor, a coworker or even a stranger in line can have a surprisingly big impact on your life. And chances are, you are seriously underestimating how much you and the other person will enjoy them.

Nicholas is a professor…

It seems like paying attention should be easy. Yet for many of us, it has become one of the hardest things to do. We start reading an article and suddenly we're checking email. We pick up our phone to do one thing and, twenty minutes later, we've forgotten why we picked it up in the first place. We often blame ourselves for lacking discipline, but what if that's only part of the story? Is our ability to focus actually being stolen—and if so, by whom? Journalist and bestselling author Johann Hari set out to answer those questions by traveling the world and interviewing many of the leading scientists and experts studying attention, distraction, and the brain. What he discovered challenges many of the assumptions we have about why it's become so difficult to concentrate and why simply trying harder isn't enough. In this fascinating conversation, Johann explains what's really happening to our attention, why deep focus matters so much for creativity, productivity, happiness, and relationships, and what all of us…

And if infidelity comes to light, is the relationship automatically doomed, or can couples actually recover? Glenn Hutchinson, a clinical psychologist and behavioral researcher, joins me to separate myth from science and reveal what decades of research tells us about why people cheat,…

Most of us think of intelligence as something that happens entirely in the brain. But there's another kind of intelligence that lives in your body. It's what allows you to ride a bicycle years after your last ride, catch a ball without calculating its path, type on a keyboard without looking, or instinctively keep your balance on uneven ground. Scientists call this physical intelligence, and it's far more important to your everyday life than you may realize. According to my guest Scott Grafton, your body and brain are constantly working together in ways you're barely aware of. In fact, many of the skills you rely on every day don't come from conscious thought at all—they come from this remarkable partnership between mind and body. Modern life, however, may be working against us. As technology makes more of our daily tasks easier and more automated, we may be losing opportunities to develop and maintain the very abilities that help us navigate the physical world. That has consequences that go well beyond…

Humans are remarkably bad at predicting how long something will take. Whether it's a home project, a work assignment, or even a quick trip across town, we almost always underestimate the time involved. Psychologists have studied this tendency for decades—and understanding why it happens can help you make better plans, meet more deadlines, and avoid unnecessary frustration. https://thedecisionlab.com/biases/planning-fallacy We tend to think of imagination as something artists, inventors, and children rely on. But imagination is actually one of the most powerful—and overlooked—abilities we all possess. It shapes the decisions you make, the problems you solve, the goals you pursue, and even the life you create. There is fascinating science behind how imagination works, and once you understand it, you can use it far more effectively. My guest is Dr. Cassandra Vieten, clinical psychologist, Director of Research at the Arthur C. Clarke Center for Human Imagination at the University of California, San Diego, and…

Anyone who has ever owned a dog has probably wondered what goes on inside that furry little head. Does your dog feel guilty after chewing up your favorite shoes? Does it know when you've had a bad day? Does it love you the way you love it? We often assume we know what our dogs are thinking, but many of our assumptions are completely wrong. Understanding how dogs actually perceive the world can transform the relationship you have with your pet. According to dog behavior expert Camilla Gray-Nelson, dogs don't think the way humans do, and many common training mistakes happen because people expect dogs to understand things they simply don't. Once you begin to see the world from your dog's perspective, communication becomes easier, unwanted behaviors are easier to change, and training becomes far less frustrating—for both of you. Camilla shares fascinating insights into how dogs interpret our actions, what motivates their behavior, and how to build a happier, more cooperative relationship with your four-legged…

When you're hungry, you know you're more interested in food. But hunger also changes the way you think—and the effects can spill over into decisions that have nothing to do with eating. Researchers have discovered some surprising consequences of making important choices on an empty stomach. https://www.dundee.ac.uk/press-release/dont-make-major-decisions-empty-stomach-research-suggests Finding cheap airfare has become almost a game. People swear by booking on Tuesdays, searching in incognito mode, or buying tickets at a certain time of day. But how much of that actually works? The truth is that airline pricing is driven by a surprisingly complex system—and once you understand what really causes fares to rise and fall, you can dramatically improve your odds of paying less. Here with an insider's look at how airfare pricing really works is Scott Keyes, founder of Going.com (formerly Scott's Cheap Flights), which tracks airfare deals for more than two million travelers worldwide.

Does your signature reveal more about you than just your name? It turns out the way you sign your name may influence what people assume about your personality, confidence, and even your success—whether those assumptions are accurate or not. Listen as I explain what your signature may be saying every time you put pen to paper. https://graciousliving.typepad.com/the_write_event/2003/11/what_does_your_.html Why do so many purchases that seem exciting at first end up leaving us...underwhelmed? We chase the next gadget, car, vacation, or pair of shoes hoping it will make us happier, yet the feeling rarely lasts. Is there a better way to spend your money so it actually improves your life? According to Harvard Business School professor Michael Norton, there is—and it has surprisingly little to do with how much you spend. Michael is the author of the book Happy Money: The Science of Happier Spending (https://amzn.to/3iFzDOq). Listen as he explains how a few simple changes in the way you spend can produce far more…

Walk through a crowded airport or packed stadium and something remarkable happens. Thousands of people weave around each other without collisions, almost as if everyone is reading everyone else's mind. Yet no one is directing traffic. So how does your brain constantly predict where complete strangers are about to move—and why does it work so well? (https://www.nature.com/articles/nature08260) Rejection stings. Whether it's being turned down for a job, ignored after asking someone out, or hearing "no" when you were hoping for "yes," most of us spend a lot of energy trying to avoid it. But what if that's exactly backward? What if deliberately seeking rejection could make you more confident, more successful, and surprisingly happier? Jia Jiang decided to test that idea by intentionally getting rejected 100 times in 100 days. What happened changed the course of his life—and it may change the way you think about rejection forever. Jia is an award-winning entrepreneur, speaker, and bestselling author. His TED Talk…

Some mysteries have been solved by science. Others remain surprisingly stubborn. Despite all our advances in technology and research, there are still questions that continue to puzzle some of the brightest minds on Earth. Do we really have free will? Why does the placebo effect work? Have extraterrestrials ever tried to contact us? Those are just a few of the scientific mysteries you are about to explore. Why do these mysteries persist? Is it because we simply don't have enough evidence yet, or are some answers beyond our ability to discover? Joining me to examine some of the most intriguing unanswered questions in science is Michael Brooks. Michael is an award-winning science writer and author of the book 13 Things That Don't Make Sense: The Most Baffling Scientific Mysteries of Our Time (https://amzn.to/2NvuAmO). Listen as he explains what scientists know, what they suspect, and where the biggest gaps in our understanding still remain. If history has taught us anything, it's that today's impossible mystery…

Ever notice how your face turns bright red when you're embarrassed—and makes the whole situation even worse? As awkward as blushing feels, it isn't a design flaw. It's actually serving a purpose that's far more useful than most people realize. https://blogs.scientificamerican.com/bering-in-mind/why-we-blush-the-social-purpose-of-showing-embarrassment/ Many of us race through life without even realizing we're doing it. We hurry through meals, conversations, vacations—even our free time. But what if all that rushing is quietly making life less enjoyable and less fulfilling? According to Carl Honoré, slowing down isn't about getting less done—it's about getting far more out of everything you do. He explains why living at a different pace can transform your work, your relationships, and your happiness. Carl is author of In Praise of Slowness (https://amzn.to/43GRlXN). Music is everywhere. We choose to listen to some of it, while the rest quietly fills stores, restaurants, movies, TV shows, elevators, and…

Have you ever met someone named Lucy and thought, "She really looks like a Lucy"? As strange as it sounds, scientists have discovered there may be more truth to that feeling than you realize. Your name may actually influence the way you look—or at least the way other people see you. Listen as I explain this fascinating research and what it reveals about the surprising connection between names and faces.https://www.pnas.org/doi/10.1073/pnas.2405334121 We all give away far more than we think. Tiny facial expressions, subtle gestures, the way we sit, stand, or even touch our face can reveal confidence, nervousness, deception, attraction, and much more. Once you know what to look for, it's almost impossible not to notice these hidden signals. Joining me is Peter Collett, a social psychologist who taught at Oxford University and is internationally recognized for his expertise in human behavior and nonverbal communication. He is author of How To Tell What People Are Thinking From the Bedroom to the Boardroom…

Stores and restaurants don't just play music to fill the silence. The tempo, volume, and even the style of music are often carefully chosen because they can quietly influence your behavior and even how much money you spend. Once you know what's happening, you'll start hearing those playlists very differently. https://journals.sagepub.com/doi/10.1177/002224298204600313 Your brain performs an astonishing magic trick every second of every day. It decides what deserves your attention—and what doesn't. Most of the time that's incredibly helpful. But it also means important clues, costly mistakes, opportunities, and even obvious dangers can sit right in front of you without you ever noticing them. Why does that happen, and can you train yourself to see what you've been missing? Here to explain is Keelan Leyser, a digital illusionist and one of the world's leading experts on attention and perception. Along with the late neuropsychologist David Lewis, he is co-author of the book Unseen: Blind Spots and Why We Miss…

Most of us spend a lot of time trying to be happy and avoiding sadness whenever we can. But what if sadness isn't something to fear or eliminate? What if it's one of the most important emotions we have? Why do we cry when we're grieving—but also when we're overwhelmed with joy? Why does listening to sad music often make us feel better instead of worse? And when does a good cry actually help us recover, while other times it only leaves us feeling stuck? According to David Huron, sadness isn't simply an unpleasant emotion we have to endure. It serves important psychological and biological purposes that help us cope with loss, strengthen relationships, and even prepare us for the future. Understanding how sadness works can change the way you experience difficult moments and help you recognize the difference between healthy sadness and harmful rumination. David Huron is Professor Emeritus at Ohio State University and author of The Science of Sadness: A New Understanding of Emotion. Remarkably, he has made the…

Most of us think we're pretty good drivers. But even experienced drivers develop bad habits without realizing it. Fortunately, a few simple adjustments can make you a safer, more alert driver—and could even help you avoid a serious crash.https://www.nhtsa.gov/road-safety Ask people to name the greatest investor of all time and chances are Warren Buffett will top the list.

Why do mosquitoes seem to feast on some people while barely bothering others? It turns out your attractiveness to mosquitoes has much less to do with "sweet blood" than with your body chemistry, the carbon dioxide you exhale, and even your skin microbes. Understanding what really attracts mosquitoes can help you avoid becoming their favorite summertime meal. https://hartfordhealthcare.org/about-us/news-press/news-detail?articleId=42234&publicid=395# Most people think eating healthier means giving up the foods they love and following a restrictive diet. Unfortunately, that's one reason so many diets fail. According to nutrition expert Dr. Sarah Ballantyne, you don't need to obsess over what you can't eat. Instead, the key is making sure your body gets the nutrients it needs while working with the foods you already enjoy. Dr. Ballantyne is founder of Nutrivore.com and author of Nutrivore: The Radical New Science for Getting the Nutrients You Need from the Food You Eat (https://amzn.to/4cREoPN). She explains…

If your porch light seems to attract every moth and flying insect in the neighborhood, you're not imagining it. Scientists have finally figured out why artificial lights are so irresistible to many insects—and knowing what they've discovered can help you keep more bugs away this summer. https://www.nature.com/articles/s41467-024-44785-3 Some people seem to light up a room the moment they walk in. Others naturally draw people in, inspire confidence, and make lasting impressions. We call it charisma, and many assume you're either born with it or you're not. Olivia Fox Cabane says that's simply not true. In this conversation, she explains what charisma really is, why it's often misunderstood, and the surprisingly practical skills anyone can learn to become more influential and engaging.

Few foods are as American as the hamburger. Every year, Americans eat billions of them, and they are a staple at backyard barbecues, diners, ballparks, and restaurants around the world. Yet despite being one of the most recognizable foods on the planet, no one seems to agree on where the hamburger actually came from. Like many great origin stories, the history of the hamburger has become tangled in myth, hometown pride, and competing claims. Over the years, dozens of people and places have been credited with inventing it, but separating fact from folklore isn't easy. That's what prompted award-winning author and historian Chris Carosa to approach the mystery the way a detective would—by following the evidence wherever it led. Using classic investigative techniques, Chris dug through historical records, newspaper accounts, business documents, and eyewitness reports to piece together the hamburger's true story. His research reveals how the sandwich evolved, why so many people claimed to invent it, and how it…

Take a look at your speedometer the next time you're driving. Chances are, it's lying to you. The speed you're actually traveling is probably different from what the dashboard says—and that's completely intentional. https://en.wikipedia.org/wiki/Speedometer?utm From the time we're children, we're constantly reminded to "sit up straight" and "don't slouch." We've been told that good posture prevents pain, improves health, and even makes us more confident. But how much of that is actually supported by science? According to Beth Linker, surprisingly little. In this conversation, she explores where our ideas about posture came from, why so many assumptions have gone unchallenged, and what the evidence really says about the way we sit, stand, and move. Beth is a former physical therapist, medical historian, and author of Slouch: Posture Panic in Modern America (https://amzn.to/4480Hhk).
