The big price drops on Wall Street in recent days have had many people worried. We asked people on social media to send us some questions about the stock market volatility and we turned to economist Austan Goolsbee for answers.

The U.S. has around 800 military bases outside of the nation's borders. They're home to hundreds of thousands of troops and family members, and, in many cases, they're a cause of controversy.

David Vine, an associate professor of anthropology at American University, argues that we've become too dependent on such overseas bases — and that many of them cause serious opposition abroad. He lays out his thinking in his new book, Base Nation: How the U.S. Military Bases Abroad Harm America and the World.

Marion, Ohio, just north of Columbus, used to be an idyllic place to grow up.

Kelly Clixby and Beth Carey remember what it was like a generation ago, when they were young.

"I lived across the street from one of the big parks here," Clixby says. "We would rip n' run all day and all night and come in when the street lights were on."

"It was just a nice place to live," Carey says.

Today, Marion is different. It's grappling with a full-blown heroin epidemic, one that derailed Kelly Clixby's life and killed Beth Carey's twin sister.

In 1998, Ben Lecomte swam across the Atlantic Ocean. The 47-year-old athlete is preparing for another historic plunge: swimming across the ocean on the other side of the country.

At the end of September, Lecomte plans to take off from a Tokyo beach and spend the next six months making his way some 5,500 miles across the Pacific Ocean to San Francisco.

He'll swim for eight hours a day, then board a support boat to eat and sleep. The next day he'll jump back in the water at the exact same spot.

The rise of Donald Trump as a Republican presidential candidate has surprised many pundits, but not conservative commentator Glenn Beck.

Trump has widened his lead over other Republican presidential candidates in public opinion polls. Other non-professional politicians, including Dr. Ben Carson, a brain surgeon, and Carly Fiorina, the former head of Hewlett-Packard, have also shot ahead of politicians in the polls.

Voters are angry, and they "want somebody just to say it the way they think it — especially if they say it in a non-politically correct way," Beck says.

The year since Michael Brown died in Ferguson, Mo., several confrontations between African-Americans and police have become national stories. Often, black journalists have been leading the coverage on these incidents and the steady trickle of them have taken a psychological toll. Many of them shared their experiences with Gene Demby of NPR's Code Switch team.

Though Larry Wilmore had always hoped to be a performer, his early career was as a comedy writer. He wrote for shows like The Fresh Prince of Bel Air and In Living Color, and created The Bernie Mac Show. He moved in front of the camera as The Daily Show's "senior black correspondent" in 2006. So when Stephen Colbert ended The Colbert Report last year, Comedy Central tapped Wilmore to host the replacement show.

A new clinical trial is set to begin in the United Kingdom using the powerful noses of dogs to detect prostate cancer in humans.

While research has been done before, these are the first trials approved by Britain's National Health Service.

The trials, at the Milton Keynes University Hospital in Buckinghamshire, will use animals from a nonprofit organization called Medical Detection Dogs, co-founded in 2008 by behavioral psychologist Claire Guest.

A man in his early 40s with a kind, weathered face is talking to a room full of children.

"In some ways, all of us are basically abandoned or not really a wanted person," he says. "Everybody kind of give up the hope on us. But in this place, you are welcome and you have opportunity to change, and we will be with you, no matter what. This is a community of love and compassion."

Cara Nicoletti loves food almost as much as she loves books. Over the years she has found herself thinking about the delicious dishes woven into the stories she loved as a child. In fact, she tells NPR's Rachel Martin that when she re-read her old books, she found underlines that she didn't remember making in the sections about food.
