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.

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.

What if ticks were an endangered species? Would we preserve critical habitat for them? Fund a captive-tick breeding program? It would be hard for me, as a hiker and dog owner, to summon any sympathy for these disgusting little pests. If they were gone, would the greater environment miss them in any way? Just a fantasy. Ticks are, of course, thriving and a new report from the U.S. Centers for Disease Control finds that they are, in fact, responsible for 10 times more Lyme disease than previously thought - 300,000 cases a year nationwide.

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.

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...
