The California condor is big. In fact, it's the largest flying bird in North America with a wingspan of 9 1/2 feet.

Michael Mace, curator of birds for the San Diego Zoo Safari Park, tells NPR's Arun Rath that the condor "is like the 747 compared to a Cessna if you look at it proportionally with other species like eagles and turkey vultures."

Mace works in a condor power line aversion training program at the zoo. It was developed to address the condors' unfortunate run-ins with power lines.

About an hour's drive south of Kabul, there's a vast Buddhist archaeological site dating back at least 1,500 years. It happens to be sitting on top of one of the biggest untapped copper deposits in the world, potentially worth billions of dollars.

Are most people more likely to pull the trigger of a gun if the person they're shooting at is black?

A new meta-analysis set out to answer that question. Yara Mekawi of the University of Illinois and her co-author, Konrad Bresin, drew together findings from 42 different studies on trigger bias to examine whether race affects how likely a target is to be shot.

There's a song out there right now that's catching a lot of people off guard. "S.O.B" sounds kind of familiar, maybe like a revived oldie, but it's not: It's fresh off the new self-titled album from the Denver ensemble Nathaniel Rateliff & the Night Sweats.

On why he left Perry to work for Trump

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.
