...teen drivers: The study warns that danger lurks as today's text-happy teens become a larger proportion of drivers on the road. Drawing on earlier research, they also report that teens are four times more likely to get into an accident related to overall cell-phone use than adult drivers...
...PNAS study contains some other less than surprising facts - for instance, adult females swing conservatively when it comes to tree travel, while males and adolescents are the risk takers. But the ultimate point is that orangutans, as odd and ungainly as they look, are uniquely adapted to the jungle, to life among the trees - an existence that is being threatened by the continued logging of Southeast Asian jungles. "Orangutans can move in logged forest, but the energetic cost may be much greater, and food availability is likely to be lower, so populations become less healthy and less viable...
...recent years, the world has increasingly been cleaving into two zones: smoking and nonsmoking. In the U.S. and other developed countries, Big Tobacco is in retreat, chased to the curbs by a combination of lawsuits, smoking bans, rising taxes and advertising restrictions. Fewer than 20% of adult Americans now smoke - the lowest rate since reliable records have been kept - and a tobacco crackdown is under way in Europe, Canada and elsewhere. In April, Congress boosted federal cigarette taxes threefold, from 32 cents a pack to $1. In June, President Barack Obama signed a law giving the FDA the power...
...harm the developing brain is unclear, though more than one mechanism may be at work. "We know from many studies that the developing fetal brain is particularly vulnerable to neurotoxic chemicals," says Perera. "One of the reasons is that it is rapidly developing. The defense mechanisms present in the adult are not present in the fetus: these include detoxification and repair enzymes." Exposure to pollution could cause direct genetic damage or epigenetic changes, which are changes in how genes are expressed...
While the U.S. ranks a respectable second (after Norway) in producing adult workers with bachelor's degrees, it has slipped to ninth in producing working-age "sub-bachelor's" degree holders, which is one reason Obama is working on a plan to help every American get at least one year of college or vocational training. "If you're going to increase the population that has some college, it isn't going to be among upper-middle-class white people," says Thomas Bailey, director of Columbia University's Community College Research Center. "Community colleges will have to play a central role...
