New U.S. government research indicates that female military veterans commit suicide at nearly six times the rate of other women and at rates nearly equal to that of male veterans -- a finding that surprised researchers because women are generally are far less likely than men to commit suicide. The findings raise questions about the backgrounds and experiences of women who serve in the United States' armed forces. [more inside]
One day in the fall of 1981, eight men in their 70s stepped out of a van in front of a converted monastery in New Hampshire. They shuffled forward, a few of them arthritically stooped, a couple with canes. Then they passed through the door and entered a time warp. Perry Como crooned on a vintage radio. Ed Sullivan welcomed guests on a black-and-white TV. Everything inside — including the books on the shelves and the magazines lying around — were designed to conjure 1959. This was to be the men’s home for five days as they participated in a radical experiment, cooked up by a young psychologist named Ellen Langer.
"Especially with the country in great need of donation, science should speak louder than stigma in determining who can help."
Tainted: Why Gay Men Still Can't Donate Blood - "Since 1983, Food and Drug Administration (FDA) guidelines have disqualified men who have ever had sex with men (MSM) from donating blood... Uneven application of exclusion to at-risk individuals suggests that risk aversion disproportionately impacts MSMs. For example, a non-MSM individual who has had sexual contact with a commercial sex worker or HIV-positive partner is deferred for only twelve months... The fact that the U.S. upholds a lifetime ban on MSM donation while Australian policy allows MSM individuals to donate a year or less after contact reveals a glaring discrepancy. Both ethics and science point to a flaw in FDA policy. That I could have had sex with 365 partners this year and be a perfectly fine candidate for donating blood, while the MSM next to me wouldn't qualify, betrays a faulty line of logic." [more inside]
Light marijuana use doesn't harm lung function, study found: "Smoking a joint once a week or a bit more apparently doesn't harm the lungs, suggests a 20-year study that bolsters evidence that marijuana doesn't do the kind of damage tobacco does."
The Harvard Study of Adult Development is the longest prospective study of mental and physical well-being ever conducted. For 72 years, researchers at Harvard have been following 824 individuals through war, career, marriage and divorce, parenthood and grandparenthood, and old age. Designer Laura Javier took ten of those cases and visualized them in the Elements of Happiness. [via flowingdata]
A recent study, commissioned by the UK Food Standards Agency, has found that there is no evidence that organically produced foods are nutritionally superior to conventionally produced foodstuffs. On the basis of a systematic review of studies of satisfactory quality, there is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs. The small differences in nutrient content detected are biologically plausible and mostly relate to differences in production methods. Who cares?
A study from researchers at the University of Alberta concludes that unhappy workers perform their tasks at the same rate as happy workers, but with about half as many errors (more inside).
