Engineers say technologies like spray-on clothing and 3D-printed shoes could help future Olympians break records. The Institution of Mechanical Engineers' Philippa Oldham discusses how technology impacts sporting performance and why engineers should work closely with regulators.
Florida's Aquarius Reef Base is the only working undersea lab left today. But now that federal funds have dried up, it may be forced to surface.

ERIC MCCORMACK: (As Doctor Daniel Pierce) In this class, we're interested in what goes on in the brain. And if we were to put someone in an FMRI machine and watch what happens when they make up a lie, we'd see their dorsolateral prefrontal cortex light up like a Christmas tree...
MCCORMACK: (As Doctor Daniel Pierce) ...because we use our brains when we lie. We use our brains when we're being lied to. But can the brain ever lie to itself?

Romney said he was addressing the nation, not as "political candidate," but as "a father, a grandfather, a husband, an American." Now, he said, "is the time to look into our hearts and remember how much we love one another and how much we love and how much we care for our great country."
Sylvia Woods, known as the Queen of Soul Food, died yesterday at age 86. She opened the legendary Sylvia's restaurant in Harlem 50 years ago, around the corner from the Apollo Theater, and it soon became a gathering place for prominent African Americans, politicians, and foodies of all ages and races.
As deeply as the mass shootings in Aurora, Colo., shocked the national conscience, they also quickly affected the U.S. political scene, with both major party presidential campaigns ripping up their scripts for Friday, and the mayor of the nation's largest city using the issue to put the candidates on the spot on gun control.
