It sounds like a fairy tale but it's real. A study shows how wild birds and people communicate to find bees' nests and share the sweet honeycomb. The teamwork may date back thousands of years or more.

Scientists who have been tracking cloud patterns over the past two decades say the shifts they're seeing seem to correlate closely with what's predicted by computer models of Earth's changing climate.

Enjoy Juno's trip to Jupiter — after that we'll see a little gap in planetary science missions from the U.S. That's because a NASA budget crunch several years ago left fewer missions in the pipeline.

More than $7 billion in drugs, vaccines and supplies are stashed in warehouses to be tapped in case of a pandemic or an attack with chemical, biological or nuclear weapons. NPR got a peek at one.

More than 99 percent of the people living in the U.S. and Europe look up and see light-polluted skies, according to a new atlas of artificial night sky brightness.

When a Wyoming woman fell ill, no one suspected that she could have rabies from a bat in her bedroom. Health officials say sleeping in a room with a bat is a rabies risk because bites are hard to see.

Usually in nature, the females choose the males they mate with. But researchers say a type of male orb-weaving spider selects the female — which will cannibalize him afterward.

The fields bend the hairs, and that generates a nerve signal, scientists say.

It's not unusual for males to try to impress females with big body parts. Consider antlers on deer, or elaborate tails on peacocks. Some male fruit flies take a different approach: giant sperm.

The women being monitored now include those who had positive lab tests but no symptoms, according to the CDC. Also affected are 122 women in U.S. territories, almost all in Puerto Rico.

The U.S. is the proud owner of the world's largest deadweight machine, used to calibrate high-tech measurement devices. Repairing it recently was risky, using 50-year-old tools. No toes were smashed.

Scientists have found the first eukaryotic organism that functions fine without mitochondria, the "powerhouses" that make energy for the cells of yeast, humans and other animals.

Of the more than 1,200 planets in the latest trove turned up by NASA's Kepler Space Telescope, about half seem to be rocky, like Earth.

Scientists say each of these planets has one searingly hot side that's always facing the star and one frigidly cold side that's always facing away. But the regions in between might be cozy.

Brain maps constructed by MRI show that language meaning is distributed throughout the brain's outer layer. And it turns out that different people organize language in similar ways.

NIH Director Francis Collins has stopped research at two leading labs for now. But an independent board of experts wants even more oversight to ensure that patient safety is the top priority.

The National Institutes of Health shut down some clinical trials and two production facilities over concerns that safety rules haven't been followed, but it says no patients appear to have been hurt.

Astronomers have found about 2,000 planets beyond our solar system. Now, some scientists are expanding the search to look for distant moons, too, in the hunt for signs of life.

A black hole with about 17 billion times the mass of our sun has turned up in another remote galaxy. Astronomers now think these mass-eating monsters may not be so rare after all.

Long known as a workplace hazard, silica dust can cause irreversible lung scarring and cancer. The Department of Labor expects its new limit to save about 600 lives a year. But industry is balking.
