Ever get a song stuck in your head that simply will not leave? That’s an earworm, and while it will eventually fade away on its own, there are some things you can do to help get rid of it sooner. Listen and discover what works. https://health.clevelandclinic.org/songs-get-stuck-head Being a good conversationalist can make an enormous difference in your personal and professional life. Yet most of us were never actually taught how to have a great conversation. How do you comfortably talk to someone you don’t know? What do you do when the conversation stalls? How do you change the subject…
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 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…
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. Source: Eat This Not That by David Zinczenko(https://link.amazon/B03ckVUuD) For decades, we’ve been told the future would bring flying cars, human-like robots, smart cities, self-driving vehicles and all sorts of other technological wonders. So…where are they? Why do so many innovations that always seem to be “just…
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…
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…
If you’ve ever tried to look at your phone while wearing sunglasses and found the screen strangely dark—or even completely black—there’s a fascinating reason why. And you don’t necessarily have to take off your sunglasses to fix it. Listen and discover a very simple trick. https://www.allaboutvision.com/eyewear/sunglasses/lenses/polarized-lenses-and-lcd-screens/ Imagine walking into a meeting, party or conference and quickly figuring out who has influence, who knows whom, who feels uncomfortable and what is really going on beneath the surface. That’s the skill of “reading the room.” Some…
How is your posture right now? If your shoulders are slouched, you may be sending a message to other people that you never intended to send. Your shoulders can communicate confidence, uncertainty, stress and more. Listen as I explain what your posture may be saying about you. https://www.jnforensics.com/post/what-the-shoulders-say-about-us Why are dogs so picky about where they poop? Can cats tell how you’re feeling? And does a goldfish really have a three-second memory? We love our pets, but some of the things they do can be baffling. Eleanor Spicer Rice is an entomologist and author of…
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…
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…
Why do your fingers and toes sometimes feel freezing cold when the rest of you feels perfectly comfortable? It’s actually your body doing something very deliberate to protect you. Listen and discover what’s going on — and why warming those fingers and toes back up can be so difficult. https://health.clevelandclinic.org/why-are-my-hands-and-feet-always-cold-and-should-i-worry Are you getting enough sleep? Is it good-quality sleep? Why did you wake up at 3 a.m.? For a lot of people, sleep has become something to measure, manage and worry about. But all that effort may actually be making sleep…
We have become much more of a cashless society in the last few years. That turns out to be a good thing because cash is really disgusting. Listen as I explain just how disgusting and you are not going to like it! Source: Elizabeth Scott, author of How to Prevent Food Poisoning (https://amzn.to/3XKAvHf). Horses are the “Swiss army knife of animals.” They can do so much. Consequently, over the last 5,000 years they have done more to shape our lives and alter human history than any other animal. If it weren’t for horses, your life today would be considerably different. That’s according to my…
Certain smells can instantly transport you back to another time and place — sometimes more vividly than a photograph ever could. Why is your sense of smell so closely tied to memory, and why are those memories often so emotional? Listen and find out. https://magazine.hms.harvard.edu/articles/connections-between-smell-memory-and-health Getting good customer service can feel like an obstacle course. You can’t reach a human being, the chatbot sends you in circles, you wait on hold forever, and sometimes it seems as if the company would simply prefer that you give up. So what actually works when…
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…
Why do leaves turn such spectacular colors every fall? It seems as if the green simply changes to red, orange or yellow — but that isn’t quite what happens. There is a lot more going on inside those leaves than you might imagine. Listen as I explain the fascinating process that creates the colors of autumn. https://www.weather.gov/dvn/climate_fall_colors When you want to make a big change — lose weight, save money, get ahead at work, break a habit — the usual advice is to buckle down and try harder. But there may be a much smarter and easier way. Research shows that where you are and who you…
Some very popular drinks can do a surprising amount of damage to your teeth. Which ones are the worst offenders? This episode begins with what certain drinks do to your tooth enamel and some simple ways to minimize the damage if you drink them. https://news.uthscsa.edu/more-u-s-teeth-susceptible-to-silent-enamel-eating-syndrome/ You are surrounded by gases every moment of your life.

When the power goes out, how long will food in your refrigerator and freezer stay safe? And how bad is it to open the door and check? Consumer Reports has some useful answers that could save you from throwing out perfectly good food—or eating something you shouldn’t. https://www.consumerreports.org/home-garden/emergency-preparedness/what-to-feed-your-family-when-the-power-is-out-a4425760304/ Before you trust an airplane, a child’s toy or just about anything else, it has probably been subjected to some serious testing—and some of those tests get wonderfully weird. Engineers have fired…
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…
Have you ever been completely stuck trying to solve a problem or come up with a new idea? There is a remarkably simple thing you can do that research shows can get your creative juices flowing. 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…
Eye contact can be tricky. Too little can make you seem bored or distracted. Too much can get uncomfortable fast. So what is the right amount? This episode begins with some fascinating research on eye contact and the subtle signals you send with your eyes. http://www.spring.org.uk/2013/07/how-eye-contact-works.php Someone tells you a secret and makes you promise not to tell. You intend to keep that promise — so why can the urge to tell someone else become so strong? Secrets can weigh on us, yet revealing one can damage relationships and destroy trust. So which secrets do we keep, which do we…
Want to significantly improve your chances of getting a good night’s sleep? There is one surprisingly simple thing you can do during the day that may actually help you sleep better that night. And no, it doesn’t involve exercise, meditation or giving up your phone. This episode begins with what it is and why it may work. https://sleepopolis.com/news/make-bed-better-sleep/ Every language and every culture has swear words. We’re taught as children not to say them, yet somehow we all learn exactly what they are. So why does swearing exist in the first place? And why are certain words considered…
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,…
Ever notice that the trip home often seems shorter than the trip there—even when the distance and travel time are exactly the same? It happens so often that researchers have given it a name: the “return trip effect.” And the explanation reveals something fascinating about how your brain experiences time. https://pmc.ncbi.nlm.nih.gov/articles/PMC3179583 You’re told to “take charge of your healthcare.” But how exactly are you supposed to do that when the doctor is the expert, appointments are short, and navigating the healthcare system can be frustrating and confusing? It turns out there is a…
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…
If you have a goal you really want to accomplish, when you start may matter more than you think. January 1st gets all the attention, but there are other dates and occasions that can give you a surprisingly powerful motivational boost. https://behavioralscientist.org/new-years-resolutions-failed-be-prepared-to-leverage-other-fresh-starts How often do you strike up a conversation with someone you don’t know very well? 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…
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…
Have you ever caught yourself saying, "It smells like rain"? It turns out that distinctive scent is very real—and it's not your imagination. Scientists know exactly where it comes from, why some people notice it more than others, and why it can signal that rain is on the way. https://www.smithsonianmag.com/science-nature/what-causes-the-smell-after-rain-180974692/ Love Amazon or hate it, there's no denying it has changed the way we shop—and perhaps the way business itself is done. But how did Amazon become so dominant? What really happened behind the scenes as Jeff Bezos built one of the…
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…
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 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…
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…
