STEVE INSKEEP, HOST:

Authorities in Los Angeles are celebrating the arrest of a suspect in dozens of fires. L.A. County Supervisor Zev Yaroslavsky told reporters that residents can finally get some rest.

ZEV YAROSLAVSKY: Our long, four-day nightmare is over. This has been, literally, a nightmare. I haven't had a good night's sleep since last week, and I'm looking forward to one tonight.

The voting in the Iowa GOP caucuses begins Tuesday night. On the last day before the caucuses, Republican presidential candidates campaigned across the state Monday. Their goal was the same — motivating supporters to leave their homes on a cold evening, go to their precinct meeting places and vote.

Steve Inskeep has the Last Word in business.

Iowa's Republican Gov. Terry Branstad is a fierce advocate for the Iowa caucuses. At times over the past four months, he has seemed frustrated that candidates have not been in the state as much as in past years.

Branstad's message over and over to the candidates was not to ignore the voters of Iowa, because they take it personally.

"They want to see the candidates, and they take their responsibility very seriously," Branstad says.

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.

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.

As India's economy rapidly expands, there is a recurring theme that plays out across the country: Plans for major development projects come into conflict with traditional ways of life centered around farming.

One of those showdowns has been dragging on for years in the eastern Indian state of Orissa. A proposed $12 billion steel plant has been facing resistance from local farmers and fishermen, but an endgame may be at hand.

The project is being promoted by the South Korea-based firm POSCO, the world's fourth-largest steel producer.
