Seven years after the suit was filed, the families of four contractors killed in Iraq have settled a lawsuit with Academi, the company formerly known as Blackwater.

If you remember, the 2004 incident produced one of the most gruesome images of the war in Iraq: the charred bodies of two Blackwater guards were hung from a bridge in Fallujah.

To me, the most interesting question in this story about Environmental Literacy is whether advocates will be able to frame the proposed graduation requirement as a tool to help teachers and students excel in a system focused on evaluation (in other words, improve test scores) or whether it will be seen as one more subject to be squished into an already-packed school year.  It’s a relevant debate.

Unfortunately, my suspicion is that as soon as the words “climate change” enter the story (which they do, at about 1:14), there are some people who will immediately see this as a political issue.

For the past several years, a group of friends has gathered every week in the living room of a suburban home in Logan, Utah, to sing long-forgotten songs. It's a fun way to spend the evening, but it's also therapy for a dear friend.

Until several years ago, Barre Toelken was a folklorist at Utah State University. He'd spent much of his life preserving sea shanties and other antique songs, but then he had a stroke and was forced to retire.

"I used to know 800 songs," Toelken says. "I had this stroke, and I had none of these songs left in my head. None of them were left."

Snowy owls are a rare sight in the United States. They usually live in the Arctic but every third or fourth winter some will venture south.

But this year, the AP reports, there is an abundance of the birds, which garnered almost mythical stature when they were featured in the Harry Potter films.

In Tuesday's primary, many of those showing up to vote will not be registered as Republicans. In New Hampshire, voters unaffiliated with either party can vote in the primary.

So-called "undeclared" voters outnumber both Republicans and Democrats in the Granite State, accounting for more than 40 percent of the electorate. That makes New Hampshire's independent vote a tempting, but elusive target.

Melissa Block speaks with our regular political commentators, E.J. Dionne, of the Washington Post and Brookings Institution, and David Brooks, of the New York Times. They discuss the jobs numbers, Obama's recess appointments and presidential campaign developments.

Now, a story with this you-can't-make-it-up headline: Americans Rescue Iranian's From Pirates. According to the U.S. Navy, yesterday in the North Arabian Sea, a Navy battle group came across a fishing vessel in distress. The crew was Iranian and they'd been held hostage for weeks by pirates. And here's the irony: The American battle group included the same aircraft carrier that Iran's government threatened earlier this week.

Today, new evidence that the pace of job growth is picking up. The government's employment report for December showed 200,000 jobs added to payrolls. The unemployment rate continued its downward trend falling to 8.5 percent.

And while that may be welcome news, as NPR's John Ydstie explains, the December report could be overstating job growth.

The NFL kicks off an exciting weekend of games Saturday when it starts its playoffs. Meanwhile, there's big news in the sport that most of the rest of the world calls football. Fox television is making a major play to air more soccer games in this country, including an English Premier League game before the Super Bowl. Sportswriter Stefan Fatsis talks with Robert Siegel about the news in both kinds of football.
