"Sexting," or sending sexually explicit images by phone, remains prevalent among U.S. teenagers despite the well-known risks and consequences, according to a new study.

University of Utah researchers found 19.1 percent of those surveyed acknowledged having sent a nude photo of themselves to another and 38 percent had received such a picture.

Every weekend, a new generation of rebels converges on downtown Havana, their tattoos, piercings, and dyed hair a world apart from the "new man" the island's revolutionary leaders dreamed of.

They claim membership in a disparate band of urban tribes -- "emos," "screamos," "repas," "mikis," "punks" and "freaks" -- but come together on G Street, one of the capital's main avenues, to drink, smoke, flirt, gossip and listen to the music that defines their clans.

Patrick Modiano of France, who has made a lifelong study of the Nazi occupation and its effects on his country, won the 2014 Nobel Prize in literature Thursday for what one academic called "crystal clear and resonant" prose.

Modiano, a 69-year-old resident of Paris, is an acclaimed writer in France but not well known in the English-speaking world. The Swedish Academy said it gave the 8 million-kronor ($1.1 million) prize to him for evoking "the most un-graspable human destinies" and uncovering the world of life behind the Nazi occupation.

Crystal Bridges Museum of American Art opened in 2011 in Wal-Mart's hometown, Bentonville, Arkansas, with a respectable collection of work by famous artists from Norman Rockwell's "Rosie the Riveter" to a George Washington portrait by Gilbert Stuart.

But the museum has just opened a massive exhibition of contemporary art called "State of the Art" that could be a game-changer. The museum is sometimes mocked by critics from outside the region for its location and Wal-Mart connections — its permanent collection was funded by Wal-Mart heiress Alice Walton — but the new show represents a serious effort to introduce contemporary art to a mainstream audience far from the rarefied galleries of hipster neighborhoods and urban centers.

Think of the United Arab Emirates in the Gulf and what springs to mind? Billowing white robes against desert dunes, camel racing and falconry or futuristic buildings needling skywards?

In a Tokyo karaoke booth thick with cigarette smoke, Shinsuke Chiba's eyes bulge as the 41-year-old rips into an enthusiastic, if somewhat misjudged, rendition of the Sex Pistols' "Anarchy in the UK".

A search team is set to salvage the wrecks of Japanese and British military aircraft which crashed in a northeastern Indian lake during fierce fighting in World War II, an organizer said Wednesday.
