You probably know that light, noise, temperature and stress can all interfere with your sleep. But what about the moon?

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 abil...

Have you ever wondered why some people seem to lose their hearing gradually while insisting they hear just fine? 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 n...

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...

Heat can make people do some strange things. It can change your mood, cloud your judgment, and even affect the way you treat other people.

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. h...

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.c...

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 tra...

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) Reje...

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...

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 astoni...

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 rec...

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.

Like many great origin stories, the history of the hamburger has become tangled i...

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 prevent...
