Women who smoke while they're pregnant are more likely to have health problems, and their babies are at risk, too. But attempts to get women to stop smoking while pregnant usually fail.

When pregnant women in Scotland got paid to quit, 23 percent of them managed to stop smoking, compared to 9 percent who quit after they got counseling, support calls and free nicotine replacement therapy, according to a study published Tuesday in The BMJ.

A judge in South Carolina has thrown out the convictions of the Friendship Nine, nine black men who integrated a whites-only lunch counter in 1961, at the peak of the civil rights movement.

Waze, the popular navigation app boasting more than 50 million users worldwide, has a new critic: police officers. Over the past few weeks, law enforcement officials have been urging the app and its owner, Google, to disable a feature that allows users to report when they've spotted a police officer, in real time, for all other Waze users to see.

Sergio Kopelev, a reserve sheriff in Orange County, Calif., is one of the law enforcement officials behind the push to remove Waze's police tracker. He says he first discovered the feature through his family.

Ask Americans if someone in their family served in the military, and the answer is probably no. After all, fewer than 1 percent of Americans serve these days.

This story begins an occasional series about individuals who don't have much money or power but do have a big impact on their communities.

Sometimes, the people you'd least expect are those who do the most. People like Tony Simmons, a homeless man in Baltimore who helps others get off the street. Simmons says he does it as much for himself as for anyone else.

If you want a sobering look at the scale of wildlife trafficking, just visit the National Eagle and Wildlife Repository on the outskirts of Denver. In the middle of a national reserve is a cavernous warehouse stuffed with the remains of 1.5 million animals, whole and in parts.

They range from taxidermied polar bears to tiny sea horses turned into key chains. An area devoted to elephants is framed by a pair of enormous tusks.
