AT&T's proposed $85.4 billion acquisition of Time Warner has cast renewed attention on the financial performance and journalistic independence of one of the media conglomerate's best-known possessions, CNN.

"You have to allow the organization to run independently," AT&T Chairman and CEO Randall Stephenson tells NPR. "It's not an altruistic thing either.

Florida Sen. Marco Rubio got booed off a stage in Orlando on Sunday, by a crowd that was overwhelmingly Latino.

It happened at Calle Orange, a street festival in downtown Orlando geared toward the city's large Puerto Rican community.

A federal judge has approved Volkswagen's $14.7 billion settlement over the carmaker's vehicle emissions scandal. The process of compensating affected U.S. car owners is beginning now, with the first buybacks expected to happen within the next few weeks.

Under the terms of the deal, Volkswagen agrees to either buy back or repair vehicles involved in the scandal. That means paying as much as $10.033 billion to owners. In addition, the carmaker has come to an agreement with the United States under which it will pay nearly $5 billion in environmental remediation.

When scientists want to know what our ancient ancestors ate, they can look at a few things: fossilized animal bones with marks from tools used to butcher and cut them; fossilized poop; and teeth. The first two can tell us a lot, but they're hard to come by in the fossil record. Thankfully, there are a lot of teeth to fill in the gaps.
