The horror of Agent Orange and its effects on Vietnam war veterans and Vietnamese citizens is well-documented.

But many U.S. veterans who never fought in that war say they, too, handled toxic chemicals at military bases around the world, suffering the same health consequences. Retired Lt. Col. Kris Roberts is among them.

It's been less than six months since Freddie Gray, a 25-year-old African-American man, died after sustaining severe injuries in police custody. At the time, Gray's death set off days of demonstrations in Baltimore — as well as rioting and criminal charges against six police officers. Those officers have all pleaded not guilty.

We often hear the story of the Second World War through the experiences of American and British soldiers pitted in battle against Germany and Japan.

But the largest volunteer force in the world then was the Indian Army: More than 2 million Indian men fought for Britain, even as Indian citizens struggled to be free of the British Empire.

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.

On Sept. 4, 2005 — nearly a week after floodwaters submerged much of the city, a call came in to the New Orleans Police Department: Officers in distress, maybe under fire, at the Danziger Bridge.

It all starts with a strange letter left for a Beijing cabdriver, tucked away in the sun visor of his taxi. In the months just before the 2008 Summer Olympics, Wang Jun is living with his wife and daughter — but the message, and those that follow, quickly tangle that quiet life in complications.

Jon Cleary's songwriting is pure New Orleans. The pianist and singer has absorbed every last bit of sound from the Mississippi delta. But here's the thing: Cleary was born and raised in England.

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."
