It sounds, at first, like a bold, next-generation solution: personalizing guns with technology that keeps them from firing if they ever get into the wrong hands.

But when the White House called for pushing ahead with such new technology as part of President Obama's plan to cut gun violence, the administration did not mention the concept's embattled past. As with so much else in the nation's long-running divisions over gun rights and regulation, what sounds like a futuristic vision is, in fact, an idea that has been kicked around for years, sidelined by intense suspicion, doubts about feasibility and pressure tactics.

In years past, Novak Djokovic marked his victories at the Australian Open with rowdy late-night celebrations and bleary-eyed photo shoots the next morning in downtown Melbourne.

This year's win made history but inspired a more sober reaction.

Japan launched two intelligence satellites into orbit on Sunday amid growing concerns that North Korea is planning to test more rockets of its own and possibly conduct a nuclear test.

He's acted, danced and sang his way through movies, television and the stage, making Dick Van Dyke an entertainment triple-threat long before Hollywood used such hyphenates.

The 87-year-old actor, best known for the 1960s hit comedy "The Dick Van Dyke Show" and Disney's big-screen musical "Mary Poppins," can now add lifetime achievement honoree. He added that honor to his resume at Sunday night's 19th annual Screen Actors Guild Awards.

Mourners at a U.S. fast-food fan's funeral wanted him to have it his way, so they arranged for his hearse — and the rest of the procession — to make one last drive-thru visit before reaching the cemetery.
