Something You Should Know

What makes someone—or something—attractive? It may have less to do with beauty and more to do with how easily your brain can process what you’re seeing. There’s a hidden pattern behind what we find appealing, and it shows up in more places than you might expect. https://pmc.ncbi.nlm.nih.gov/articles/PMC3130383/?utm

Artificial intelligence is evolving rapidly, and it’s easy to feel like you’re either falling behind—or overestimating what it can actually do. So what is AI truly good at right now? Where does it fall short? And how can you use it effectively without getting lost in the hype? Christopher Mims, technology columnist for The Wall Street Journal and author of How to AI: Cut Through the Hype. Master the Basics. Transform Your Work (https://amzn.to/3Qtnd0n), breaks down what today’s AI tools can realistically do, how they differ, and how to get real value from them in your everyday work and decision-making.

Have you ever been in a room where you felt like you didn’t quite belong? Maybe you held back from speaking, worried about saying the wrong thing, or felt subtly out of place. That feeling has a name: “churn.” Claude Steele, social psychologist at Stanford University and a leading researcher on identity and perception, explains how this tension arises and how it shapes behavior in powerful ways. In his book Churn: The Tension That Divides Us and How to Overcome It (https://amzn.to/4tZoQl9), he offers insight into why we feel this way—and what we can do to move through it with more confidence and connection.

Should you shut your computer down when you’re done with it—or just let it go to sleep? It seems like a small choice, but the answer may not be what you think—especially given how much technology has changed. https://support.microsoft.com/en-us/windows/shut-down-sleep-or-hibernate-your-pc-2941d165-7d0a-a5e8-c5ad-8c972e8e6eff

Being a little skeptical can feel smart. After all, cynics pride themselves on “seeing things as they really are”—not getting fooled, not trusting too easily. But is that actually true? Or does cynicism quietly distort the way you see other people and the world?

Research suggests that cynicism may come with a significant cost. People who assume the worst in others often miss opportunities for connection, collaboration, and even personal success. In fact, believing that others are selfish or untrustworthy can become a self-fulfilling cycle—one that shapes how you behave and how others respond to you.

Dr. Jamil Zaki, professor of psychology at Stanford University and director of the Stanford Social Neuroscience Lab, studies empathy, trust, and human connection. In his book Hope for Cynics: The Surprising Science of Human Goodness (https://amzn.to/3XeRfpL), he explores what science actually says about human nature—and why many of us are far more trustworthy and cooperative than cynics assume.

In our conversation, he explains why cynicism feels protective, why it spreads so easily, and what you can do to challenge it without becoming naïve. If you—or someone you know—tends to expect the worst, this perspective may change the way you think about people and your place among them.

What if you followed people for 80 years—tracking their health, happiness, and relationships over a lifetime? That’s exactly what one of the longest-running studies ever has done, and what it reveals about how to live a good life may not be what you expect. https://www.adultdevelopmentstudy.org/

We all think we know what “now” means—until we try to define it. The present moment feels obvious, yet science struggles to explain it. Your brain doesn’t have a clear way to register “now,” and your experience of time can stretch, compress, and shift depending on what you’re doing and how you feel. Jo Marchant, science writer and author of In Search of Now: The Science of the Present Moment (https://amzn.to/4tKBvbs), explores how we experience time, why it feels different from moment to moment, and how we can become more aware participants in the way we perceive our lives unfolding.

Most people have encountered someone who drains their energy, creates conflict, or leaves them feeling worse after every interaction. These “poisonous” individuals often display traits like manipulation, lack of empathy, or extreme self-centeredness. The real challenge isn’t just recognizing them—it’s knowing how to deal with them without letting them take a toll on your well-being. Dr. Leanne ten Brinke, psychologist at the University of British Columbia and author of Poisonous People: How to Resist Them and Improve Your Life (https://amzn.to/4dT7e5w), explains how to identify these patterns, why they’re so impactful, and what you can do to protect yourself.

Getting too little sleep can do more than make you tired—it can change what your body craves. Interestingly, it has something in common with another behavior that also increases hunger in a very specific way—and not for the healthiest foods. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3763921/

When you buy fruits and vegetables, how much pesticide residue is actually on them? Is it something you should worry about—or not? And does buying organic really make a meaningful difference? Recent findings offer some answers that may surprise you. https://www.consumerreports.org/health/food-contaminants/produce-without-pesticides-a5260230325/

We tend to believe that hard work and good decisions determine how life turns out. But luck and random chance play a much bigger role than most people realize. From career paths to relationships to financial success, unexpected events often shape outcomes in powerful ways. Mark Robert Rank, professor at Washington University in St. Louis and author of The Random Factor: How Chance and Luck Profoundly Shape Our Lives and the World Around Us (https://amzn.to/3W1mDb4), explains how luck operates in everyday life—and how understanding it can help you better navigate uncertainty and make smarter choices.

Every living thing ages—but not at the same rate. Some organisms live for just days, while others survive for centuries. What determines how quickly we age? And is it possible to slow the process in humans? Venki Ramakrishnan, Nobel Prize-winning molecular biologist and author of Why We Die (https://amzn.to/49KII0z), explains what science has uncovered about aging, why it happens, and what current research suggests about extending healthy lifespan.

You’ve heard the advice to stop and smell the roses—but there may be something else just as powerful you’re overlooking. Paying attention to certain everyday sounds could have a surprisingly positive effect on how you feel. https://www.treehugger.com/why-do-birds-sing-5179422

Cravings can feel almost impossible to resist—whether it’s something sweet, salty, or just tempting in the moment. Yet, there is a simple and somehow satisfying way to stop yourself or at least eat less of what you are craving than you might otherwise. https://en.wikipedia.org/wiki/Habituation

Your body works in amazing ways. For instance your immune system acquires intelligence over time, how you breathe can have a big impact on preventing disease, and the benefits of human touch are extraordinary. Dr. Giulia Enders, physician, star of the Netflix series Hack Your Health, and author of Organ Speak: What It Really Means to Listen to Our Bodies (https://amzn.to/4tyaxn9), explains how these and other hidden processes work—and how understanding them can help you live healthier and feel better.

Arguments have a way of escalating quickly. Once emotions take over, people often double down, defend themselves, and say things that make the situation worse. But there’s a very different approach that can calm someone down much faster. Doug Noll, mediator, adjunct professor at Pepperdine University’s Straus Institute for Dispute Resolution and author of De-Escalate: How to Calm an Angry Person in 90 Seconds or Less (https://amzn.to/4cCqJy1), explains how to respond in a way that reduces tension, diffuses anger, and leads to more productive conversations.

Resistance exercise is important for everyone. And when it comes to lifting weights, many people wonder if speed matters—should you lift fast or slow? The answer isn’t as complicated as you might think, but it does depend on what you’re trying to achieve. https://pubmed.ncbi.nlm.nih.gov/25601394/
