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.

A lot of books come across our desks here at Weekend Edition. One caught our eye recently, because of the unusual way it came to be published. The title sums up the story — Underground in Berlin: A Young Woman's Extraordinary Tale of Survival in the Heart of Nazi Germany.

That remarkable tale came to light thanks to a request by her son, historian Hermann Simon. "I once put a tape recorder and said to her, 'You always wanted to tell me the story of your life. Well, go ahead.' "

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.

It's been a big year for German filmmaker Wim Wenders: He received a lifetime achievement award at this year's Berlin International Film Festival, the Museum of Modern Art had a retrospective of his work and his latest Oscar-nominated documentary, The Salt of the Earth, came out in March.

Amalie Bruun is Danish-born musician who grew up playing classical violin and piano. It didn't take long, though, before she was introduced to a more aggressive style of music, for which the Scandinavian region is especially well known.

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.

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.

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.

Donald Trump's Republican presidential campaign continues to lead in the polls, and this week Trump hired Sam Clovis to be his national campaign co-chairman. A week ago, Clovis worked for Republican rival Rick Perry. Clovis, a former radio talk show host and college professor, is an Iowan who has run for state treasurer and the U.S. Senate there. He Talked to NPR's Scott Simon from Sioux City, Iowa.

On why he left Perry to work for Trump

If you've ever visited the Fells Point neighborhood on the Baltimore waterfront, you may have noticed an older man standing on the street corner, telescope in hand. Herman Heyn, self-proclaimed "star hustler," has been setting up in the same place almost every night, offering passersby glimpses of the galaxy for close to three decades.

He knows, because he's been keeping count.

"I just finished my 27th year. I've been out on the street 2,637 times," he says. "It's like being on a Broadway show that has a long run."

Clock yourself the next time you tie your shoes. Chances are, in the time it took you to get those shoes laced up, Ronda Rousey would have knocked out her opponent in a typical mixed martial arts match.

The late Terry Pratchett wrote more than 40 books about the Discworld, a magical flat land borne through space on the backs of four elephants and a giant cosmic turtle. The Discworld is full of memorable characters: Werewolf constables, cunning rulers, snooty vampires, con men, trolls and dwarves and mystery-sausage sellers. But the most memorable of all are the witches — not green-skinned and cackling, but tough, practical women who use "headology" rather than spellcasting, and whose mission is to help people "when life is on the edge."

It can take years for a musician to discover his or her voice. But in the meantime, they find themselves by discovering the music of other artists. With a wide-ranging catalog spanning 30 years, Yo La Tengo is its own band, but the trio has become just as noted for its huge repertoire of cover songs.

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.

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).
