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.

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.

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.

Ursula Le Guin has brought mainstream recognition to science fiction in a successful career that has endured for sixty years, with books that include The Left Hand of Darkness, Lavinia, and the Earthsea series for young readers.

On why he left Perry to work for Trump

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."

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.

Since 1971 Sonia Manzano has been one of the lucky residents of Sesame Street. As Maria, she guided Big Bird, Elmo and the rest of the gang through life lessons large and small. After 44 years, Manzano recently announced her retirement, but her dedication to help kids continues.

Manzano's new memoir Becoming Maria is a poignant and difficult book meant for teens and adults. In it, she tells her own story of growing up in a Puerto Rican family in the South Bronx in the '50s and '60s. There was love, but also violence brought on by her father's drinking.
