In Afghanistan, the killings are called "green on blue" — that's when an Afghan soldier or police officer turns his gun on a NATO ally.

There was a wave of such violence just last month after U.S. soldiers accidentally burned Korans. Over the next week, six Americans were killed, apparently at the hands of Afghans working with the U.S.

The top U.S. and NATO commanders in Afghanistan think they have some answers to this recurring problem, and it's up to U.S. soldiers like Capt. Joe Fritze to see if they work.

This story broke Wednesday in the Anchorage Daily News, but it has too much going for it not to pass along.

Monday night while competing in Alaska's Iditarod dog sled race, Scott Janssen's 9-year-old husky Marshall collapsed.

"Janssen raced to the dog," the newspaper writes. "Marshall did not appear to be breathing."

"I know what death looks like, and he was gone. Nobody home," Janssen told the Daily News.

This is from a few days ago, but we missed it until The Atlantic pointed it out today.

We know Congress is divided. But how much so?

Here's a graph The Atlantic dug up from data The National Journal has put together using data they've collected for about 30 years analyzing congressional votes:

Meet Willow Tufano, age 14: Lady Gaga fan, animal lover, landlord.

In 2005, when Willow was 7, the housing market was booming. Home prices in some Florida neighborhoods nearly doubled from one month to the next. Her family moved into a big house; her mom became a real estate agent.

But as Willow moved from childhood to adolescence, the market turned, and the neighborhood emptied out. "Everyone is getting foreclosed on here," she says.

The solar storm that swept over Earth Thursday didn't seem to cause any major problems, as some had feared.

But the prediction that it would create some beautiful Northern Lights has proved to be quite true. The Associated Press has moved a quite striking photo taken Thursday on the east coast of Iceland.

The National Association for the Advancement of Colored People announced it will appear before the United Nations' Human Rights Council in Geneva next week to seek support for its fight against voter identification laws enacted in U.S. states.

The civil rights organization says the laws are among several measures adopted by some states that violate the human and civil rights of minority voters by suppressing their participation in elections.

The Department of Education's top civil rights official, Russlynn Ali, speaks with host Michel Martin about a new report. It finds students of color have less access to high-level classes, their teachers are often paid less than those of white students in same district, and suspension rates for black students are disproportionately high.

Unmanned aircraft systems, or drones, have long played a role in military operations. But imagine thousands of drones flying over U.S. skies — something we may see in just a few years. In February, President Obama signed an aviation bill requiring the Federal Aviation Administration to make plans to integrate drones into American airspace.

What is it with heavy metals showing up in cosmetics?

First it was lead in lipstick. Now, the Food and Drug Administration warns that some beauty products made overseas contain mercury.
