Family farmers are angry about the proposal and accuse the government of encroaching on a sacred part of country life. But statics show kids who work on farms are six times more likely to be killed than children working in other industries. Peggy Lowe of Harvest Public Media reports.

Campaigning in the Democratic Republic of Congo has taken a stormy turn. Veteran opposition politician and presidential candidate Etienne Tshisekedi proclaimed himself president, and ordered his supporters to stage jailbreaks to free their detained colleagues.

The Environmental Protection Agency says the Asarco copper smelter in Hayden, Arizona, has been continuously emitting illegal amounts of lead, arsenic and eight other dangerous toxins, for the last six years. The agency's finding means Asarco could face millions of dollars in fines and could be forced to install expensive pollution controls.

President Obama traveled early Thursday to the Australian city of Darwin, a base for past U.S.-Australian military cooperation. Now it will be one of several military bases from which the U.S. operates as it seeks to reassert itself in Asia.

Some 250 U.S. Marines will arrive in northern Australia next year, a number that will later expand to about 2,500. U.S. jets and warships will also train with the Australians.

Abraham Denmark, a China specialist at the Center for Naval Analyses, sees the new focus on Asia as a natural evolution of U.S. interests.

Scientists say they are beginning to understand why brain injuries are so common in very premature infants — and they are coming up with strategies to prevent or repair these injuries.

The advances could eventually help reduce the number of premature babies who develop cerebral palsy, epilepsy or behavioral disorders such as ADHD, researchers told the Society for Neuroscience meeting in Washington, D.C., this week.
