One year ago, protesters across the Arab World began to rise up against autocratic rulers, forcing several from power. These revolutions have led to the region's biggest upheaval in decades. It's still not clear how these seismic changes will play out, and so far, the results have been mixed. In a six-part series, NPR is taking a look at where the region stands today. In the second installment, NPR's Lourdes Garcia-Navarro reports on how Islamists in Libya, long suppressed during Moammar Gadhafi's 42-year rule, are now able to operate freely.

For some of America's lowest-paid workers, the new year means a pay raise. Some states set their own minimum wages, above the federal rate of $7.25 an hour, and that rekindles an old debate over whether minimum wages make sense — especially at a time of high unemployment.

Like several other states, Washington state's minimum wage is indexed to the cost of living. This year, the formula has raised the statewide minimum from $8.67 to $9.04 an hour, making it the nation's highest statewide rate.

One of the more controversial episodes of the Iraq war will be revisited in a military courtroom in California this week.

In November of 2005, a Marine squad killed 24 Iraqis, some of them women and children in the village of Haditha. Staff Sgt. Frank Wuterich led the squad of Marines, and on Wednesday he'll face voluntary manslaughter charges at Camp Pendleton.

Saudi Arabia said Monday that it will enforce a law that allows only females to work in women's lingerie and apparel stores, despite disapproval from the country's top cleric.

There's a lot of debate these days about the cost of medical care and the risks. Is a drug for breast cancer patients worth the $100,000 price tag if it only adds a few months to a woman's life? Or should men routinely get blood tests for prostate cancer when the exam could cause more suffering than it prevents?

Well, today, a major medical group issued new ethical guidelines on whether doctors should consider cost when deciding how to treat patients. As NPR's Rob Stein reports, the group takes a provocative position.

Brazil had record trade figures in 2011, logging $256 billion in exports and maintaining a $29.7 billion surplus on the back of high commodity prices and strong Chinese demand, officials said Monday.

Exports to China hit $44.3 billion, an increase of more than 43 percent over 2010. In 2009 China surpassed the U.S. as Brazil's biggest trading partner.

"It was an exceptional year for Brazilian foreign trade," said Alessandro Teixeira, deputy trade minister, who said China represented 17 percent of Brazil's exports.
