Scientists have turned a textbook example of sexual selection on its head and shown that females may be more astute at choosing a mate than previously thought. New research shows that differences in the lengths of the long tail feathers possessed by male barn swallows are an example of natural selection, not sexual selection.

Toshiba has announced plans to ship an organic electroluminescence (EL) display in 2009. The target size will be 30 inches, which beats most manufacturers' prototypes currently under development, like Sony's 27-inch OLED plans. Toshiba had previously planned 2015 as the launch window for OEL (more commonly known as OLED) sets, a launch timeframe which put them in that magical future land along with SED and FED displays. While Toshiba doesn't expect to compete directly against the behemoth of LCD at first, they believe the technology's superiority -- which includes lower manufacturing costs, and better viewing angles and contrast -- will be recognized as volume goes up. Your electroluminescent game of fl0w may never look better.

Researchers have identified a protein that they say is key to helping a quarter of all breast cancers spread. The finding could be a potential target for new drugs aimed at stopping or slowing the growth and progression of breast cancer.

Anthropologists have new evidence that ancient farmers in Mexico were cultivating an early form of maize, the forerunner of modern corn, about 7,300 years ago -- 1,200 years earlier than scholars previously thought.

The proportion of Americans who are severely obese -- about 100 pounds or more overweight -- increased by 50 percent from 2000 to 2005, twice as fast as the growth seen in moderate obesity, according to a new study.

Planting and protecting trees -- which trap and absorb carbon dioxide as they grow -- can help to remove carbon dioxide from the atmosphere. But a new study suggests that, as a way to fight global warming, the effectiveness of this strategy depends heavily on where these trees are planted. In particular, tropical forests are very efficient at keeping the Earth at a happy, healthy temperature.
