Underage drinkers who participated in a study to see if they could buy alcoholic beverages online were successful in 45% of attempts. The study, conducted at the University of North Carolina at Chapel Hill, recruited eight people, ages 18 to 20, to try to purchase wine, beer and other beverages online, according to Bloomberg News. To keep participants on the right side of the law in case they got caught, each got a letter of immunity from the local district attorney. The participants were instructed, for the purposes of the study, to lie about their age when filling out order forms.

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.

Consider this next time you're sitting in traffic on the freeway: You're in a zone where air pollution can be five to 10 times higher than in surrounding areas. Even inside your vehicle, you're probably breathing in pollutants through the windows or the air vents. After an hourlong commute, you've likely doubled your daily exposure to the harmful particles in vehicle exhaust. A new study says the single best thing you can do to protect yourself is roll up the windows and set your vehicle's ventilation system to 'recirculate.' Using that setting -- typically a button that shows a car with an arrow inside -- can cut pollution concentrations inside a typical car to 20% of on-road levels, scientists found.
