Providence, R.I., has a history of mob violence rivaling that of New York or New Jersey, but it comes with a gritty intimacy that could only be found in the nation's littlest state. Author Bruce DeSilva says that's what makes Providence the perfect place to set his crime fiction.

"It is big enough to have the usual array of urban problems," he says. "But it's so small that it's claustrophobic. It's very hard to keep a secret in places like that."

There's no magic elixir for healthy aging, but here's one more thing to add to the list: good gut health.

A study published in the latest issue of Nature finds diet may be key to promoting diverse communities of beneficial bacteria in the guts of older people.

To evaluate this, researchers analyzed the microbiota, or gut bacteria, of 178 older folks, mostly in their 70s and 80s.

The new Batman film, The Dark Knight Rises, is perhaps the most anticipated movie of the summer. It's the last film in the Batman trilogy that writer-director Christopher Nolan has crafted over the past 7 years.

Nolan wanted The Dark Knight Rises, which will be released in theaters July 20, to feel like a historical epic. As he tells weekends on All Things Considered host Guy Raz, he looked to films like Fritz Lang's Metropolis, David Lean's Dr. Zhivago, and Ridley Scott's Blade Runner.

A legal showdown is evolving. It affects an American university, the British government, a brutal Irish paramilitary organization and the murdered mother of 10 children.

Journalist Ed Moloney is fighting to keep secret interviews with former paramilitary members of the Irish Republican Army out of the British government's hands. Those interviews are kept under lock and key at Boston College as part of an oral history project that Moloney started in 2001.

When you hear the word chia, you probably think of chia pets. Maybe you even mutter that catchy slogan: "ch-ch-ch-chia."

Or maybe not, but lately, chia seed has been getting buzz beyond those terra cotta figurines. It's becoming a popular health food. Rich in fiber, protein and the highest plant source of Omega 3s, the little seeds pack a major nutritional punch.

Wayne Coates grows and sells chia seeds and has a book called Chia: The Complete Guide to the Ultimate Superfood.

Academy Award-winning actress Celeste Holm has died. A star on both stage and screen, Holm was best known for roles in Gentleman's Agreement, All About Eve and Oklahoma! She was 95.

Holm died early Sunday morning in her Manhattan apartment with her husband, family and close friends by her side. She had been hospitalized a couple weeks ago following a fire in actor Robert De Niro's apartment in the same building.

If there was one role that put Holm on the map, it was as the coquettish Ado Annie, in the 1943 hit musical, Oklahoma!

The Greek capital of Athens has suffered from an image problem since the debt crisis began more than two years ago. Media reports often show masked gangs throwing petrol bombs at Parliament or riot police dousing demonstrators with tear gas.

Many tourists are staying away as a result. Tourist arrivals to the city are down by between 20 and 40 percent, industry representatives say.

The Green Party nominated a Massachusetts physician and a formerly homeless single mother as their presidential and vice-presidential candidates for 2012 on Saturday. They say they are in it to win it, and — at the very least — to expand the electoral conversation to include people they say aren't represented by either Democrats or Republicans.

Amid waving green and white campaign signs in a conference room at a Baltimore Holiday Inn, the room erupted in cheers as Dr. Jill Stein won the delegate count.

As a journalist, I came to Pamplona to see if Spain's dismal economy would dampen the spirit of the country's biggest summertime festival, the running of the bulls. Spaniards take their partying very seriously, and if there were even a hint of melancholy in their chants of "Viva San Fermin!" it might mean the economy devils had won.

Maria Arvizu continues to fill out job applications even though she has yet to deposit her last paycheck.

Arvizu, 53, relocated to Yuma, Ariz., to become a bus driver for the local school district last year. After school closed for summer break, she was caught off guard when she was laid off. She had expected to get another driving assignment and was denied collecting unemployment because she was still considered a school employee.

"I just keep looking for a job," Arvizu says.

At some point today, you will probably flip on a light switch. That simple action connects you to the oldest and most plentiful source of American electricity: coal.

Since the early 1880s — when Edison and Tesla pioneered the distribution of electrical power into our homes — most of that power has come from the process of burning coal.

In some of the dirtiest places on Earth, author and environmentalist Andrew Blackwell found some beauty. His book, Visit Sunny Chernobyl, tours the deforestation of the Amazon, the oil sand mines in Canada and the world's most polluted city, located in China.

Blackwell says his ode to polluted locales is a bid for re-engagement with places people have shrunk away from in disgust.

Radioactive To Its Core

His first stop was the site of the world's worst nuclear disaster, Chernobyl.

The weekends on All Things Considered series Movies I've Seen a Million Times features filmmakers, actors, writers and directors talking about the movies that they never get tired of watching.

Opinions about Dirty Projectors couldn't be more divided. At a recent NPR Music listening party, audience members gave the band's new album, Swing Lo Magellan, both very high marks and very low marks. It was a genuine split decision.

Intrigued, weekends on All Things Considered spoke with Dirty Projectors bandleader Dave Longstreth to figure out why. One thing became clear pretty quickly: Longstreth and Dirty Projectors take a lot of risks.
