Columbus, Ind., looks like any other small town, with its small shops and restaurants. But what sets this town apart is its architecture.

The Modernist buildings — mostly geometric and made of glass and steel — are not immediately visible, interspersed as they are with old, 19th-century, gingerbread-like structures; but more than 60 public buildings in Columbus have been built by a veritable who's who of modern masters — I.M. Pei, Eero and Eliel Saarinen, Cesar Pelli, Richard Meier, Harry Weese, Robert Venturi and James Polshek, to name a few.

Viola da gamba players are a special breed — a tiny subset in the already small world of early classical music. They rarely meet their own kind, but once a year they come together for a week in July at an annual jam session they call a conclave. Wendy Gillespie, who just finished her term as president of the Viola da Gamba Society of America, says attending the event is the highlight of her year.

Earlier this year, the Australian government added the koala to the country's list of endangered species. By some counts, only about 100,000 remain in the wild in a country that once boasted a population in the millions. But many conservationists say the listing doesn't go far enough.

Paul O'Donnell is one of the many volunteers at Friends of the Koala in the northern New South Wales town of Lismore.

"We go out every day for about an hour or so collecting leaf; usually we get about one bin per koala," O'Donnell says.

That New Hampshire Sen. Kelly Ayotte is even being considered as Mitt Romney's running mate is somewhat remarkable. After all, New Hampshire has just four electoral votes, and Ayotte has been a U.S. senator — her first elected office — for less than two years.

But if any senator could be said to possess a refreshing charm, it might be Ayotte, 44, a mother of two young children, who still lives in her hometown of Nashua and is married to a former combat pilot.

No one's entirely sure where the Southern treat called the Goo Goo Cluster got its name.

The iconic candy from Nashville, Tenn., celebrates its 100th birthday this year. The confection of marshmallow, peanuts and caramel wrapped in milk chocolate may owe its longevity in part to another Nashville icon: the Grand Ole Opry.

Goo Goo Cluster sponsored the venue's radio broadcasts from 1966 until 2006. In one popular advertisement, stage performers crooned, "Go get a Goo Goo ... it's gooooooood!"

Mali is a country rich in culture, both old and new.

The banging of hammers on silver echos through the main crafts market in Bamako, Mali's capital. It's usually teeming in a place where you can buy anything, from silver earrings to batik fabric, all of it handmade.

And despite its remote location, Mali has enhanced its cultural reputation in recent years with an annual international music and arts festival in the Sahara Desert near Timbuktu, drawing both African and Western artists.
