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.

When Fear the Walking Dead premiers Sunday night on AMC, don't expect to see Sheriff Grimes. There's no Daryl, either. In fact, the streets aren't even overrun yet with those dirty, hungry hoards of the undead that viewers know so well.

Still, something weird is happening — and it's happening in LA, not Atlanta, this time around. Fear, a prequel to the hit show The Walking Dead, swaps the post-apocalyptic Deep South for the West Coast, where that apocalypse still has yet to happen (or is just getting underway).

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.

Thousands of people are set to descend on the Black Rock Desert of Nevada for the annual Burning Man Festival, starting August 30. But before their arrival, the campgrounds were visited by another group of guests: bugs.

John Curley is a photographer and blogger for the Burning Man website. He says he first noticed the bugs at a gas station near Black Rock.

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.

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.

High-profile, officer-involved fatalities across the country have put police departments everywhere under more scrutiny than ever.

For a lesson in how to move forward, they could look at the history of the Los Angeles police.

In the '80s and '90s, Los Angeles was trapped in a cycle of crime, crack and gang warfare. Investigative journalist Joe Domanick says back then, the Los Angeles police just made things worse with its crime-fighting strategy — which involved using military-style tactics to subdue and arrest suspects, who were mostly from minority neighborhoods.

In this season of anger in many black communities that are reacting to police brutality, we're remembering the largest urban riot of the civil rights era.

Fifty years ago this week in Los Angeles, the African-American neighborhood of Watts exploded after a young black man was arrested for drunken driving. His mother scuffled with officers and was also arrested, all of which drew an increasingly hostile crowd.

President Obama's perhaps most notable statement on race came recently in Charleston, S.C. That's where he gave the eulogy for nine African-Americans killed by a white man in a church.

The president has also continued to address the killings of black men at the hands of the police, and he's pushing to reduce the number of prison inmates, who are disproportionately black.

One of the key questions surrounding the Iranian nuclear deal is what it means for the country's so-called "breakout time." That's the length of time Iran would need to produce enough highly enriched uranium to make one nuclear weapon.

The deal would limit Iran's nuclear activity in ways that stretches the breakout time. There's a general consensus that the current breakout time is around two to three months, and that would be extended to around a year under the agreement.

Migrants are arriving in record numbers in Greece, and two boatloads of men, women and children landed Monday on the Greek island of Chios in the Aegean Sea.

All Things Considered host Melissa Block has relatives in her extended family on the island. Her husband's cousins have been assisting the migrants, who are arriving via Turkey from Afghanistan and Syria, as they reach the rocky shores.

As events marking the anniversary of the shooting death of Michael Brown were winding down Sunday night, gunfire erupted in Ferguson, Mo., leaving a gunman in the hospital. Police say the suspect was not part of the weekend's rallies, which have been peaceful.

The shooting, in which dozens of rounds were reportedly fired, began near the intersection of Ferguson Avenue and West Florissant Avenue, the epicenter of last summer's standoffs between protesters and police.

Ten years after floodwaters from Hurricane Katrina breached the levees, inundating and devastating the city, many residents feel the city is making significant headway, according to a new poll by NPR and the Kaiser Family Foundation, which nonetheless reveals deep racial disparities in the recovery.

NPR's David Greene speaks with Liz Hamel, director of public opinion and survey research at the Kaiser Family Foundation about the survey findings.

It has been exactly one year since police officer Darren Wilson shot and killed 18-year-old Michael Brown in Ferguson, Mo. Mourners there marked the anniversary Sunday with a moment of silence, gathering in remembrance and protest of the shooting.

Michael Brown's father spoke before a crowd of hundreds, according to St. Louis Public Radio's Camille Phillips. Around noon, Phillips reports that the crowd was called upon for 4 1/2 minutes of silence.

Heavy metal is one music culture whose concerts can get pretty aggressive. Stage divers often try to climb up with the band then launch themselves into the awaiting arms of the audience — or that's the idea. In the city of Prague in 2010, one fan wasn't so lucky: At a particularly unruly show by the band Lamb of God, Daniel Nosek fell off the stage, hit his head and died weeks later.

Jennine Capó Crucet was the first person in her family to be born in the United States. Her parents came to Florida from Cuba, and she grew up in Hialeah, a suburb of Miami that is 95 percent Hispanic.

For Crucet, going to Cornell was a bit of a shock — she was the first person in her family to attend college at all, let alone at a prestigious school in upstate New York.

In tiny Tupper Lake, N.Y., a tourist destination in the Adirondacks, the Donut Shop serves up more than just donuts.

The Donut Shop also a laundromat, with a store selling knick knacks and souvenirs on the side. Co-owner Tina Merrihew says it's a winning combination.

"About 25 years ago, we bought it, and after cleaning out, we realized we had a lot of space in here, so we added the store," Merrihew says.

Locals and out-of-towners can come in with their dirty clothes and sit for a while with a coffee and watch it spin.

Louis Sachar knows a few things about writing for kids. His first book, Sideways Stories From Wayside School, came out in 1978 — and the wacky collection is still in print.

His 1999 Newbery Medal winner, Holes, centers on a boy wrongly confined to a juvenile detention facility. It's mysterious and creepy, and it's still flying off the shelves.

So if he says kids will love a scary eco-bioterror-mystery-thriller-comedy, you just might trust him.

The vote by the Boy Scouts of America to lift its ban on openly gay troop leaders last week was a blow to some religious conservative organizations that have long been connected to scouting, especially the Mormon church, which has deep roots in the Boy Scouts.

The church, also known as The Church of Jesus Christ of Latter-day Saints, has used the Boy Scouts as its official program for young men for more than 100 years, according to Quin Monson, a political science professor at Brigham Young University.
