- Most people think dogs see the world only in black and white—but that's simply not true. Dogs do see color, just not the same colors you do. Understanding how your dog actually experiences the world explains everything from why certain toys are easier to find to why some colors practically disappear. It's a fascinating glimpse into life through your dog's eyes. Source: https://www.psychologytoday.com/us/blog/canine-corner/200810/can-dogs-see-colors
Disasters strike without warning, leaving people with only seconds to react. Yet those first few moments often determine who survives and who doesn't. Surprisingly, the biggest factor isn't always physical strength, experience, or even luck. It's how your brain responds under extreme stress. Amanda Ripley has spent years studying real-life disasters and the people who lived through them. She explains what happens inside your mind during an emergency, why so many people freeze or make dangerous decisions, and what you can do now to dramatically improve your chances when the unthinkable happens. Amanda is author of the book The Unthinkable: Who Survives When Disaster Strikes—and Why (https://amzn.to/4fGJakN).
Many people think spending lots of time alone is a sign that something is wrong—that you're lonely, antisocial, or missing out on life. But research tells a very different story. Solitude, when chosen rather than forced, can improve creativity, emotional resilience, relationships, and even your overall well-being. Psychologist Netta Weinstein explains why healthy solitude is one of the most misunderstood tools for living a happier, healthier life—and how to know whether you're getting too much, too little, or just the right amount. She is author of the book Solitude: The Science and Power of Being Alone (https://amzn.to/3X1XkWf).
Your phone goes almost everywhere you do—into your hands, your pocket, your car, the kitchen, even the bathroom. Along the way, it quietly picks up far more than texts and emails. The surprising part isn't that your phone is covered with germs—it's how easily those germs can wind up on you. Listen as I explain why your phone deserves more attention than you probably give it and the simple habit that can keep it from becoming a health hazard.

It turns out this isn't simply denial or stubbornness. The way hearing fades can fool the brain into believing everything is normal—often delaying treatment until significant hearing has already been lost. Listen as I explain what's really happening and why recognizing the signs isn't nearly as easy as you might think. Source: https://www.nidcd.nih.gov/health/age-related-hearing-loss
Few things are more painful—or more confusing—than discovering a partner has been unfaithful. Why do people risk everything for an affair? Is it simply a lack of self-control, or is something much deeper happening beneath the surface? 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, what their behavior really means, and what happens next. He is author of the new book Unfaithful Minds: The Science and Psychology of Infidelity (https://amzn.to/3UedjS8).
Why do smart, capable people forget appointments, lose their train of thought, make impulsive decisions, or struggle to stay focused—even when they know better? The answer lies in something called executive function, the remarkable system in your brain that quietly manages attention, planning, memory, emotional control, and decision-making. When it works well, life feels easier. When it doesn't, the consequences can show up everywhere. Adrian Owen, professor of cognitive neuroscience at the University of Western Ontario, explains how executive function shapes nearly everything you do—and, more importantly, what you can do to strengthen it. He is author of the new book Think Before You Think: Understanding and Mastering Executive Function (https://amzn.to/4fGvlFd).
Why do so many projects seem to fly along at first... only to crawl painfully toward the finish line? Whether you're remodeling a house, writing a report, or tackling a long to-do list, there's a surprising psychological reason the last stretch often feels endless. Once you understand what's happening, you'll have a much better chance of finishing on time instead of wondering where all the extra time disappeared.

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 athletic performance.
Scott Grafton is a professor of neuroscience at the University of California, Santa Barbara, and author of the book Physical Intelligence: The Science of How the Body and the Mind Guide Each Other Through Life (https://amzn.to/3aiI4dm). Listen as he explains how physical intelligence shapes the way we learn, move, solve problems, and interact with the world—and why challenging your body may be one of the best things you can do for your brain.

It can change your mood, cloud your judgment, and even affect the way you treat other people. Scientists have discovered that hot weather has a surprisingly powerful influence on the human mind—and the effects show up in places you would never expect.

More people today say they feel their lives lack meaning and purpose than at any point in recent decades. Why? Has modern life quietly stripped away something essential—or are we simply searching for fulfillment in all the wrong places? And if purpose really is the key to a happier life, where does it actually come from? There is no better person to explore these questions with than my guest Arthur Brooks. He is a professor at Harvard Business School, one of the world's leading experts on happiness and human flourishing, a nationally syndicated columnist, CBS News contributor, and co-author with Oprah Winfrey of the bestselling book Build the Life You Want. His latest book is The Meaning of Your Life: Finding Purpose in an Age of Emptiness (https://amzn.to/4yUyVTp). If you've ever wondered what truly gives life meaning—and why so many people struggle to find it—you'll find this conversation fascinating.
Every few months it seems we're told to stop eating one food and start eating another. Fat is bad—until it isn't. Carbs are the problem—unless they're not. With so much conflicting advice, it's no wonder so many people have no idea what a healthy diet actually looks like. According to Daniel Lieberman, much of what we've been taught about food is based on myths, misconceptions, and oversimplified thinking. Lieberman is Chair of the Department of Human Evolutionary Biology at Harvard University and author of Fed Up: A Hungry Person's Guide to the Story and Science of Food and Diets (https://amzn.to/4btal2d). He explains what the science really says, why nutrition has become so confusing, and how understanding our evolutionary past can help us make smarter decisions about what we eat.
Have you ever worried that everyone could tell you were nervous? Maybe before giving a presentation, going on a date, or walking into an interview? Most of us assume our anxiety is obvious—but is it? The answer may surprise you. Listen as I reveal what researchers discovered about how well other people can actually read your emotions. https://pubmed.ncbi.nlm.nih.gov/9731312/

15/08/2026 | 54 mins.Ever wonder why you're always told to wait about 10 seconds before turning your phone, computer, router, or tablet back on after rebooting it? Is there really something magical about 10 seconds, or is it just one of those tech myths everyone repeats? The answer has to do with what happens inside your device after the power goes off—and why waiting just a little while can make all the difference. https://www.howtogeek.com/165110/do-i-really-have-to-unplug-my-cable-modem-for-at-least-10-seconds/
Americans throw away an astonishing amount of perfectly good food—about 40% of everything produced. That's money straight into the trash, and much of it is completely avoidable. The surprising part is that food waste often has less to do with leftovers and more to do with everyday habits, confusing expiration dates, oversized refrigerators, and the way we shop. Kathryn Kellogg explains simple, practical changes that can dramatically reduce waste, save you money, and make life a little easier. Kathryn is founder of Going Zero Waste and author of 101 Ways to Go Zero Waste (https://amzn.to/3yfHSMV)

Insects may be tiny, but they are among the most successful creatures ever to inhabit Earth. They pollinate crops, recycle dead plants and animals, feed countless other species, and have survived for hundreds of millions of years. Yet most of us know almost nothing about them. Why are there so many insects? What's the difference between a bug and an insect? Why do some live only a day while others survive for decades? And what would happen if they disappeared? Steve Nicholls answers these questions and reveals why the future of insects is closely tied to our own. Steve is an Emmy Award-winning wildlife filmmaker and author of Alien Worlds: How Insects Conquered the Earth, and Why Their Fate Will Determine Our Future (https://amzn.to/4d1M1mP).
An afternoon nap might seem like an indulgence, but research suggests it can be one of the easiest ways to improve alertness, memory, learning, and even problem-solving ability. The key isn't sleeping for hours—it's knowing how long to nap so you wake up refreshed instead of groggy. Listen as I explain why a short daytime snooze can actually make you smarter. https://www.prevention.com/health/sleep-energy/a69068628/are-naps-healthy/
