Christine Porter is hooked on the MyFitnessPal app. In October, after deciding to lose 50 pounds, Porter started typing in everything she eats, drinks and any exercise she gets.
"This is my main page here," says Porter. "It's telling me I have about 1,200 calories remaining for the day. When I want to record something I just click the 'add to diary' button. I'm on it all day either through my phone or through the computer."
President Obama listens to French President Francois Hollande during the G-8 summit at the Lough Erne golf resort in Enniskillen, Northern Ireland, on Tuesday.
You have to wonder if President Obama ever thought, when he first ran for the White House, that he would need to defend himself from accusations his presidency would be a mere extension of his Republican predecessor.
But there he was with journalist Charlie Rose having to explain why his approach to national security wasn't really like that of President George W. Bush and Vice President Dick Cheney.
Melissa Block talks to Republican Congressman Mac Thornberry, who serves on the House Permanent Select Committee on Intelligence. He talks about the testimony by leaders of the National Security Agency, the Department of Justice and the FBI on Tuesday morning. He's been supportive of the NSA surveillance program, saying it's not only legal, but vital to security.
Women in the U.S. military will be integrated into front-line combat units by 2016, the Pentagon says. Here, female Marine recruits stand in formation during pugil stick training in boot camp earlier this year at Parris Island, S.C.
Women in America's armed services will have new options for what units they can join in coming years, the Pentagon says. The military said in January that it will end its combat exclusion that set a minimum size for units in which women could be deployed; the limit kept many women away from front-line combat units. The shift means women could join elite forces such as the Army Rangers and Navy SEALs.
