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.

There are more refugees in Europe today than at any other time since World War II. As record numbers of people flee violence in Syria, Iraq and Afghanistan, as well as conflicts across North Africa, the most popular route to Europe is across the Aegean Sea to Greece.

This time last year, what became known as #Gamergate rocked the Internet and the world of video games.

The stated purpose of the hashtag movement, according to those who supported it, was that it was about corruption and ethical malfeasance in video game journalism, but the debate — played out largely on Twitter, Reddit and other discussion websites — highlighted rampant sexism and harassment in video game culture.

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.
