Getting a good grip on your health may mean … getting a good grip. The force you can muster when squeezing an object or a weight doesn't only reveal how strong your hand and arm are. It can be a measure of overall muscle function and — according to one recent study — even portend how long you're likely to live. That's not as nutty as it seems, says Richard Bohannon, a professor of physical therapy at the University of Connecticut. "Grip strength reflects your overall muscle status and a general sense of how much muscle mass you have" he says.

People who are socially isolated are more likely to die prematurely, regardless of their underlying health issues, according to a study of the elderly British population. The findings, published online Monday in the Proceedings of the National Academy of Sciences, showed that when mental and physical health conditions were factored out, the lack of social contact continued to lead to early death among 6,500 men and women tracked over a seven-year period. "They're dying of the usual causes, but isolation has a strong influence," said study author Andrew Steptoe, an epidemiologist at University College London.

By quizzing small children about the first events they remember — a cousin misbehaving, a trip to a grocery store, a mother's bribe of red and green licorice — researchers have discovered that the earliest memories of children shift as they get older, and don't solidify into the first memories carried throughout life until about age 10. The research, published Wednesday in the journal Child Development, could help psychologists better understand...

Forget that stereotype about the dumb jock. A new study reveals that kids who are more physically fit score higher on geography tests, too. Previous research has found that out-of-shape kids get lower grades in school and perform worse on tasks involving memory and other types of cognitive function. In addition, mice that exercise have better spatial learning and memory than sedentary mice. For the new study, researchers from the University of Illinois at Urbana-Champaign wondered whether there was a correlation between physical fitness and learning.

Don't press the like button: Facebook is a bummer that makes us feel worse about our lives, according to new research. Facebook users in a study led by the University of Michigan wound up feeling worse about themselves after two weeks, and their moment-to-moment mood darkened the more they browsed the social medium. It didn't seem to matter how big their network was, how supportive they thought their friends were, nor why they went to Facebook in the first place, according to the study published online Wednesday in PLOS One . "We were able to show on a moment-to-moment basis throughout the day how people's mood fluctuated depending on their Facebook usage,” said University of Michigan social psychologist Ethan Kross, lead author of the study.

Why do our eyes open wide when we feel fear or narrow to slits when we express disgust? According to new research, it has to do with survival. In a paper published Thursday in the journal Psychological Science, researchers concluded that expressions of fear and disgust altered the way human eyes gather and focus light. They argued that these changes were the result of evolutionary development and were intended to help humans survive, or at least detect, very different threats.
