The Gallup Organization, one of the polling industry's oldest brand names, is calling in an outsider to do a comprehensive review after its 2012 election polls consistently favored Republican candidate Mitt Romney.
University of Michigan professor Michael Traugott, a past president of the American Association for Public Opinion Research, has been working with Gallup since December to test several of its methods. Among them: how many interviews are conducted by cellphones; how it measures likely voters and early voters; and how it assesses the impact of get-out-the-vote efforts.

Immigrants from Asia and Latin America are more conservative than their U.S.-born children, according to a study released Thursday by the Pew Research Center.

Some 66 million years ago, about 75 percent of species on Earth disappeared. It wasn't just dinosaurs but most large mammals, fish, birds and plankton. Scientists have known this for a long time just from looking at the fossil record. If you dig deep enough, you find lots of dinosaur bones. And then a few layers up, they're gone.
But scientists couldn't figure out exactly what had caused this phenomenon. Of course, there were lots of theories.
