When children are gunned down in their classrooms, as happened last month in Newtown, Conn., it's time to say "enough," former Rep. Gabrielle Giffords, D-Ariz., tells ABC News.

Ali Harzi, the only person who had been known to be in custody in connection with last September's attack on the U.S. mission in Benghazi, Libya, has been released by authorities in his native Tunisia, the suspect's lawyer tell The Associated Press.

Saying they're following the example of last year's Chick-fil-A Appreciation Day, a coalition of "gun rights" activists announced today that they're calling on like-minded Americans to visit gun stores, gun ranges and gun shows on Jan. 19 in a show of unity they're calling "Gun Appreciation Day."

Back in 2009, as Morning Edition reported, some scientists were worried that the small metal cylinder used as the world's standard for what a kilogram should be might be losing weight.

But there were also those who thought the problem might have nothing to do with that carefully sealed away cylinder in Paris — that the real problem might be that the 40 replicas sent around the world are gaining weight.
