Beaver cites last month's prevention study as key to understanding how to best make use of his latest findings on MAO-A and gang membership. If policymakers wish to prevent violence, he says, money would be better spent not hunting for gene-based drugs, say, but expanding and improving neighborhood-based intervention programs, such as early childhood education and after-school activities...
...much easier and cost-effective to modulate an individual's environment than it is to alter their genetic code," says Buckholtz. And until the gene is better understood, that investment will pay off for those with the MAO-A defect and those without...
...recycled TP makes up about 20% of the at-home market. Recycled material simply can't match the level of comfort that virgin fiber provides - and that U.S. consumers have come to expect. "They won't go for a green product unless you can make it equal to or better than the conventional alternative," says Kimberly-Clark spokesman Dave Dickson...
...surprise that poor sleep habits may negatively impact academic performance - anyone who's been exhausted enough to doze off during class knows that's detrimental to learning. And dozens of studies have linked an increase in nightly sleep to better cognition and alertness. The new research, however, goes a step further, quantifying the impact of erratic or inadequate sleep on grades. "These findings are more tangible than saying that if you get more sleep, you'll feel better," says Jennifer Cousins, a fellow at the University of Pittsburgh and author of one of the studies. "They connect sleep...
Interestingly, Cousins also found that different sleep habits had different effects on the student's school performance: those who woke up more often during the night and reported poorer sleep quality did worse in math, for example, while those who slumbered peacefully through the night tended to get better grades in English. "These findings bring up new questions about teasing out the specifics of what is important about sleep that impacts learning," says Cousins. "Does sleeping more help our ability to deal with abstract concepts found in math, or does sleep quality increase creativity? We don't know the answers...
