Why Does NASA Study Earth?

Earth is a complex, dynamic system we do not fully understand. To learn more about it, NASA, as the agency with access to space, was tasked with launching the first weather satellite back in 1960. Today, NASA uses satellites, aircraft and even an occasional boat to study our planet's air, land and water. It's called "Earth System Science" and we are trying to answer some big questions: How is the global Earth system changing? What causes these changes? How will Earth change in the future? And what we learn benefits society through applications such as weather forecasting, freshwater availability and disaster response.

The Happiest People Don't Let Their Minds Wander

Inc. Magazine: 

A recent Harvard study reveals that stray thoughts and wandering minds are directly related to unhappiness. The study discovered that those with constantly wandering minds were less likely to be happy than those able to focus on the tasks at hand.

This study seems to confirm what Buddhists, sages, and saints have long taught--that an unruly mind creates unhappiness and dysfunction, and that the keys to happiness lie in mastering the mind, and not in changing external factors in our lives.

The most startling part of the discovery is that unhappiness doesn't just come from the mind wandering to unpleasant things. The study shows that people with minds that wander to neutral or even pleasant thoughts are still less happy than if the mind did not wander at all.

So You Think You're Creative?

Studio 360 revisits an episode that explores the source of creativity: 

We're always talking about creativity, but what do we mean? Can we find creativity, can we measure it, can we encourage it? Kurt talks with Gary Marcus, a psychology professor about what science tells us about creativity. A researcher puts jazz musicians into an fMRI machine and has them improvise; an intrepid reporter gets her creativity tested and scored; and a little girl introduces us to her imaginary friends (all of them).

Talking With Your Hands Makes You Learn Faster

Drake Baer for The Science of Us: 

The University of Chicago psychologist Susan Goldin-Meadow has spent much of her career trying to grasp (yes, pun intended) what’s happening when people talk with their hands. As Goldin-Meadow defines it, “co-speech gesture” is different from action, like grabbing a cup of coffee or combing your hair, and it’s different from movement for movement’s sake, like in dance, ritual, or exercise. The gestures that hearing people make are also quite different from sign language; in signing, Goldin-Meadow says, there are distinct units of expression, and signs only relate to other signs. But with gesture, hand movements blur together, and they only really make sense relative to what someone’s saying. “Gesticulation isn’t divorced from speech. It’s completely tied to your speech,” Goldin-Meadow tells Science of Us. “It’s part of your cognition. It’s not just mindless hand-waving.” Researchers haven’t yet pinned down exactly how this connection works, but Goldin-Meadow believes part of it is that gestures reduce what psychologists call “cognitive load,” or the amount of mental energy you’re expending to keep things in your working memory.

All those times I've said that I'm thinking with my hands turn out to be true.
