Bertha Vazquez has taught earth science for more than twenty-five years.

"For many years I covered the basic standard, probably like most people in the country do."

Then one day she says she decided to throw all that out the window when she saw former Vice President Al Gore speak at the University of Miami at a screening of An Inconvenient Truth, his documentary about climate change.

"And it really ... hit me. This is 2007 and, I've got to tell you, I lost sleep," Vazquez says.

The list of preventive services that women can receive without paying anything out of pocket under the health law could grow if recommendations from a group of mostly medical providers are adopted by federal officials later this year.

You could see the contrast in the eyes of the respective candidates' spokespersons, surrogates and family members after the first presidential debate of 2016 had wrapped.

As always, earnest efforts were made on both sides to claim victory — even insist on it — after the nationally televised clash between Democratic nominee Hillary Clinton and Republican nominee Donald Trump.

"Trump was especially strong on the issues in the first 45 minutes," said former Trump campaign manager Corey Lewandowski on CNN.

For the past couple of decades, night owls with the munchies have flocked to a certain street in Beijing which is packed with all-night restaurants, sidewalks jammed with cars and a perpetual patina of rancid-smelling cooking oil on the sidewalks.

One of the trendier restaurants on the block is called A Very Long Time Ago. The décor is upscale Paleolithic, with silhouettes of cavemen traipsing across the walls. The clientele is not so fossilized. They're mostly 20-somethings who roast skewers of food over hot coals.

The U.S. is targeting a Chinese company and the people who run it for allegedly helping North Korea with its nuclear weapons program. It closely follows the North's fifth nuclear test, which took place earlier this month.

"Each new nuclear test...spurs this kind of scramble to do something," says John Delury, a professor of international relations at Seoul's Yonsei University. "And sanctions is the kind of preferred choice."

Donald Trump and Hillary Clinton went head-to-head Monday night in the first presidential debate.

NPR's politics team, with help from reporters and editors who cover national security, immigration, business, foreign policy and more, is live annotated the debate. Portions of the debate with added analysis are underlined in yellow, followed by context and fact check.

It's well known that Dear Leader was crazy about movies. What's less known — at least in the West — is that infamous North Korean dictator Kim Jong Il was so crazy about them that he kidnapped a South Korean actress and a movie director in 1978 and forced them to work for him for years. That story is the subject of a new documentary called The Lovers and the Despot.

People who have reached their later years may think it's primarily a time to relax, not to increase their physical activity. Not so. Previous research has suggested that exercise can improve memory and reverse muscle loss in older adults, among other benefits.

As we surf from website to website, we are being tracked — that's not news. What is news, revealed in a recent paper by researchers at Princeton University, is that the tracking is no longer just about the "cookies" that record our tastes. The researchers surveyed a million websites and found that state-of-the-art tracking is a lot more sophisticated, allowing websites to track the fingerprints left by our devices.
