...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...
...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 on a stimulant...

...those lessons is that the Arctic ecosystems are unusually vulnerable to oil spills, according to long-term research funded by some of the $1 billion settlement from Exxon. Scientists found that, thanks in part to the cold environment, oil lingered in the area for years, some of it still biologically active and toxic. Because many Arctic species have long lifespans and slow reproductive cycles, wildlife recovery has been slow. Pacific herring - a keystone of both the commercial fishing industry and the marine food web in Prince William Sound - were spawning at the time of the spill, and were hit particularly...

It will have even less impact on the company's ailing bottom line, because the Nano's profit margin is tiny, says Vaishali Jajoo, a senior automotive-research analyst at Angel Broking, an investment firm in Mumbai. "It will take at least four to five years to break even" and recoup the company's development costs, she says. There's more profit to be made from fully equipped Nanos with air-conditioning, power windows and upholstered seats, which cost about...
