There may be an octopus arms race underway. And that's not even a joke about tentacles: Octopuses are actually fighting, and potentially using weapons.

The creatures are hardly team players under the best of circumstances.

"Octopuses in general are regarded as fairly solitary animals," says Peter Godfrey-Smith, a marine biologist at the City University of New York. He is studying octopuses in Australia's Jervis Bay — specifically, the common Sydney octopus, also known as the gloomy octopus.

Teenagers often feel bound by their parents' rules, and many young people feel isolated at some point, separated from the rest of the world.

But what would life be like for a young woman who was literally isolated — and bound by rules designed to save her life?

It's a question that author Nicola Yoon explores in her new novel for young adults, Everything, Everything. For 18 years, her lead character, Madeleine, has been kept inside a sterile house, interacting only with her mother and her nurse.

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.

From African drums in Congo Square to raucous brass bands second-lining in the streets, jazz is the soundtrack of New Orleans. The history and spirit of the Crescent City can be summoned through thousands of now-classic songs.

Taking chances can sometimes lead to great art. But award-winning poet Carl Phillips says there's a risk to, well, taking risks.

"I think there has to be a place for risk and for restlessness in any kind of fully lived life, and especially I think for an artist," he tells NPR's Arun Rath. "I think it's the only way that imagination gets stimulated and continues — but I think it can easily go unchecked."

His latest work, Reconnaissance, looks for the balance between restlessness and stability — and between the raw and the refined, the omnicient and the intimate.

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.
