Kathleen Edwards is a singer-songwriter from Canada who just released her fourth album, Voyageur. There's a lot of heartache and self-doubt on the record, and that makes sense — much of it was written around the time of Edwards' divorce from her husband and musical collaborator. The song "Pink Champagne" would seem to be a case in point: It takes place at a wedding where a young bride is second-guessing her decision. But Edwards says the message of that song isn't quite so literal.

For decades, until 2010, someone appeared at Edgar Allan Poe's grave site in Baltimore before dawn on Jan. 19 — his birthday.

The mysterious visitor, who was never identified, would leave behind three roses and a half-filled bottle of cognac as a tribute to the man who wrote The Raven, The Fall of the House of Usher and other classic poems and tales.

Last night, there was no visit.

If you're bugged by cost problems you find in health care, you can draw attention to them (and blow off a little steam) by writing about them. And if you're really lucky your work might help change things.

Who knows? You might even make a little cash. Essays from four people just won them $1,000 each in the second annual Costs of Care contest.

If Newt Gingrich got a boost for his prospects in South Carolina on Thursday with rising poll numbers and an endorsement from rival Rick Perry, his second ex-wife, Marianne, seemed to be doing her best to dampen his prospects with an ill-timed interview on ABC's Nightline Thursday night.

The nation's top military officer, Gen. Martin Dempsey, is in Israel where he's expected to send a clear message: Don't attack Iran, and let the tougher sanctions take hold.

Dempsey's trip to Israel was scheduled weeks ago, but it comes at a particularly sensitive time. Iran has threatened to close the Strait of Hormuz, the key route for oil shipments, and has stepped up its naval activities.

An Iranian nuclear scientist was recently killed by a drive-by assassin, and Iran is blaming Israel.

Mitt Romney's tax returns and the tax rate he paid on his income have been hot issues in the recent Republican primaries.

"What's the effective rate that I've been paying? It's probably closer to the 15 percent rate than anything because my last 10 years, my income comes overwhelmingly from investments," the GOP front-runner recently told reporters.

So why does a multimillionaire pay just 15 percent on his income? After all, the top income tax rate is 35 percent and many middle-class people pay over 20 percent.

There are reports Thursday that Texas Gov. Rick Perry will leave the GOP presidential race, and Iowa officials announced final results of the state's Republican presidential nominating caucuses held earlier this month.

Texas Gov. Rick Perry is going to drop out of the Republican race for the White House, sources are telling The New York Times and CNN.

NPR has not independently confirmed the news.

We'll pass along more as the story develops. Perry is expected to hold a news conference at 11 a.m. ET.

With the South Carolina primary just two days away, Mitt Romney woke up to some troubling news on Thursday: The Iowa Republican Party revisited his Jan. 3 victory in the caucuses.

Party officials announced that a final certification of the votes actually put Rick Santorum ahead by 34 votes. Because some of the results from eight precincts are missing, the Iowa GOP declared the outcome a split decision.
