...results challenge the accepted notion that teens make dumb decisions because their brains are immature. Although previous research has shown that most teens' gray-matter structures - including those involved in decision-making - are less advanced than those of adults, as you would expect, until now no one had studied teens' white matter, which works along with gray matter to produce decisions. The key part of white matter is called myelin, a fatty substance that coats the individual neural strands, or axons, that make up white matter. Myelination of axons begins during childhood and is completed at the end of adolescence...
...team led by psychiatrist Gregory Berns of Emory University in Atlanta shows that adolescents who engage in more dangerous activities have white-matter pathways that appear more mature than those of risk-averse youths. White matter is essentially the brain's wiring - the neural strands that connect the various gray-matter regions, where the actual nerve cells reside, that are otherwise independent of one another. Maturation of white matter is important because it increases the brain's processing speed; nerve impulses travel faster in mature white matter. (See pictures of a diverse group of American teens...
...should hardly be a surprise that the iPhone is coming to China. Apple Inc.'s iconic mobile device is manufactured here, and an estimated 2 million have already been sold on the gray market on the mainland. But a deal announced on Aug. 28 by China Unicom, the country's second largest mobile service provider, will make the phone available to hundreds of millions of mainland consumers, opening a huge new market to Apple. China now has nearly 700 million mobile phones in use, almost as many as the next two largest mobile-phone nations - India and the U.S. - combined...
...course, it will be a long time before the iPhone is commonplace in China. The typical phone here is a $100 Nokia. China Unicom hasn't named its price for the iPhone 3G and 3GS models that it plans to bring to the market this fall, but with a gray-market 3G iPhone now going for about $575 in China, the device will be far beyond the means of the average Chinese phone buyer.

...Kureishi is a tidy man, his shirt buttoned, his gray curls - and his sentences - clipped. He was "very pleased and flattered" by his CBE and extols a recent stint teaching at Yale as "very comfy." But his spot in the cultural establishment is proof that his revolution succeeded. He's about to start on the screenplay of The White Tiger, the Booker Prize winning novel by Indian author (and occasional TIME contributor) Aravind Adiga. That a story about a poor Indian hustling his way in Bangalore sold millions of copies all over the world, notes Kureishi, shows that post-colonial...
