...idea that stimulants like caffeine (or Ritalin or even something stronger like cocaine) can help you sit still and pay attention seems counterintuitive at first. But that surprising fact lies at the heart of Rapport's work: stimulants augment your working, or short-term, memory, where information is stored temporarily and used to carry out deliberate tasks like, say, solving a challenging math problem. ADHD kids have a hard time with working memory because they lack adequate cortical arousal, and Rapport believes that their squirms and fidgets help stimulate that arousal...
...other than breaking down instructions, his answer was a bit depressing: no. ADHD is incurable. Drugs like Ritalin are a common answer for controlling the condition, which affects about 3% to 5% of children, but Rapport notes that they have proven to be only a limited solution. In the short term, they can facilitate a child's ability to read - undoubtedly a crucial benefit - but Rapport says longitudinal studies have failed to show that Ritalin or other psychostimulants have consistent long-term behavioral effects. (Even if they did, another question would arise: Would you want to be dependent...
...Home resale rates rose 5.1% in February to an annual rate of 4.72 million, according to the National Association of Realtors.

...Bristol Bay, where more than 40% of all wild seafood consumed in America is caught, the result would be not just an environmental disaster, but also an economic one. The Bristol fisheries bring in over $2 billion to the Alaskan economy annually - losing the bay even for a short time because of a spill would be "devastating," says Colburn. "We don't know the impacts on juveniles. We don't know the impacts on soft-shelled crab. To me, [oil exploration] is just such a near-sighted policy...
...Nano sales won't do much in the short run to ease the burden. But Tata Motors' efforts to pioneer cost-saving business processes during the Nano's development could translate into a healthier bottom line down the road. One of these innovations is "distributed manufacturing." Instead of investing in expensive factories and hiring additional workers as sales volumes increase, Tata Motors plans to limit Nano production at its central plant to 500,000 cars every year. Beyond that, it will use satellite plants to build the car's components and distribute these in Nano "kits" to independent entrepreneurs - trained...
