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.

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.

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.

Former Pennsylvania Sen. Rick Santorum nearly won the Iowa caucuses on the strength of his retail campaigning across all of the state's counties — and his connection with Christian conservative voters.

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.

Rick Santorum has been working hard this week to capitalize on his strong showing in the Iowa caucuses, trying to convince Republicans in New Hampshire that he is presidential material. One thing he's not encouraging possible supporters to do: Google him.
