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.

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.
