Times Online: INVISIBILITY devices, long the realm of science fiction and fantasy, have moved closer after scientists engineered a material that can bend visible light around objects.
The breakthrough could lead to systems for rendering anything from people to large objects, such as tanks and ships, invisible to the eye – although this is still years off.
Researchers at the University of California at Berkeley, whose work is funded by the American military, have engineered materials that can control light’s direction of travel. The world’s two leading scientific journals, Science and Nature, are expected to report the results this week.
Since Barack Obama inspires coolness, artists are coming out with posters, stickers and buttons, street murals and other artistic works to support Obama.

WaPo: Earlier oil shocks have had obvious causes. In October 1973, OPEC raised prices and declared an oil embargo against the United States and other countries that had supported Israel in its war earlier that month against its Arab neighbors. The embargo ended in March 1974, but pricing power had shifted from the oil companies to the producing countries. In 1979, prices soared again after the Iranian Revolution curtailed output and consumers and oil companies went on a spree of panic buying.
Now, however, there is no one culprit and no single international crisis to blame. Instead, world demand has been increasing faster than supply, steadily squeezing oil markets.
This in turn has signaled to investors that prices are inevitably heading higher. Financial players, such as Wall Street banks and hedge funds, have bet just that, investing tens of billions of dollars in oil futures. Critics on Capitol Hill and elsewhere say this speculation has turbo-charged the market, helping lift prices even more.
The tightening of the oil market reflects decisions made a decade ago, when conditions looked radically different. Regular unleaded gas was less than a dollar a gallon. Oil was little more than $10 a barrel. And the Economist magazine, predicting prices could soon be half that, ran a cover story with the headline: “Drowning in Oil.”
Those low prices sent the wrong signals to consumers and oil companies alike.
Demand for oil jumped as U.S. sales of gas-guzzling cars soared and China’s breakneck economic expansion picked up pace.
Daniel Yergin, a historian of the oil business and head of Cambridge Energy Research Associates, said that over the five years from 1998 to 2002, world oil demand grew 1.1 percent annually, raising daily consumption by 4.2 million barrels. But in the following five years from 2003 to 2007, world oil demand grew 2.1 percent annually, boosting consumption by about 8.2 million barrels per day.
