Can you damage your fingers from texting?

Half-gloves or fingerless gloves may leave fingers uncovered for texting, but they can also lead to permanent finger loss due to the cold, a U.S. expert says. Fingers are one of the first body parts to feel the effects of the cold and damp and, along with toes, ears and the nose, are frequently subjected to frostbite and even amputation," Dr. Arthur Sanford, of the Loyola University Health System, said in a statement. "Better to fat finger a text due to wearing winter gloves than to lose a finger due to the cold."

Will New Jersey become the latest gambling hot spot?

New Jersey Gov. Chris Christie has signed a law legalizing online gambling in the state that applies only to persons physically in New Jersey. The law that allows online poker, blackjack and slot machines is expected to bring in $410 million the first year, H2 Gambling Capital estimated. Revenue is expected to grow to $590 million in the ensuing years. New Jersey's take will be 15 percent of the revenue, the Wall Street Journal reported Wednesday. Online gambling, which has had a rocky history with the U.S. Justice Department, is also allowed in Nevada and Delaware.

Is nitrogen, not CO2, the real cause of China's pollution?

U.S. scientists say they have identified a key element -- human-caused nitrogen emissions -- in China's ongoing battle against severe air pollution. Researchers at Stanford University said their study indicated the amounts of nitrogen from industry, cars and fertilizer deposited on land and water in China by way of rain, dust and other carriers increased by 60 percent annually from the 1980s to the 2000s. This increase had profound consequences for the country's people and ecosystems, they said.
