"It's a jungle if you're an eagle right now on the Chesapeake Bay," says Bryan Watts, a conservation biologist at the College of William and Mary in Williamsburg, Va. "You have to watch your back."

Americans have long imagined their national symbol as a solitary, noble bird soaring on majestic wings. The birds are indeed gorgeous and still soar, but the notion that they are loners is outdated, Watts and other conservationists are finding.

Now A Test Can Tell If Your Pricey Cup Of Cat Poop Coffee Is Fake

A civet cat eats red coffee cherries at a farm in Bondowoso, Indonesia. Civets are actually more closely related to meerkats and mongooses than to cats.

From gross to gourmet. That pretty much sums up civet poop coffee.

The beans are literally harvested from the feces of the tree-dwelling civet cat in Indonesia. The idea is that a trip through the animal's digestive tract partially ferments the beans and imparts a much-sought-after flavor to the coffee.

U.S. 'Space Fence' Radar System Goes Silent, After 50 Years

A computer image generated by NASA shows objects orbiting Earth, including those in geosynchronous orbit at a high altitude. The objects are not to scale.

The Space Fence is down. That's the message we get from the SatWatch site, following up on our report last month that the U.S. Air Force was poised to shut down the radar system that tracks thousands of objects orbiting Earth. It had been in operation since 1961.

Pollution, Not Rising Temperatures, May Have Melted Alpine Glaciers

The Alps' largest glacier, Aletsch Glacier, extends more than 14 miles and covers more than 46 square miles.

Glaciers in the Alps of Europe pose a scientific mystery. They started melting rapidly back in the 1860s. In a span of about 50 years, some of the biggest glaciers had retreated more than half a mile.

But nobody could explain the glacier's rapid decline. Now, a new study from NASA's Jet Propulsion Laboratory uncovers a possible clue to why the glaciers melted before temperatures started rising: Soot from the Industrial Revolution could have heated up the ice.

The Latest In Scientific Field Equipment? Fido's Nose

Dave Vesely is busy training his dog, Sharpy. She isn't learning to sit or fetch or even herd sheep; Sharpy is learning to find the nests of western pond turtles.

These turtles are sneaky. After laying their eggs in a small hole, they knead together dirt, leaves and their own urine to plug the opening. Once this mud dries, the nest looks like an unremarkable patch of ground.

A consortium of companies and universities in Alabama and Tennessee are hoping to develop a site where drones would be tested.

If approved, the facility could become one of only a half-dozen sites approved by the Federal Aviation Administration for research involving Unmanned Aerial Systems, more commonly known as drones.

Alabama and Tennessee have submitted a joint application in an effort to be selected as one of the six FAA UAS testing sites. Testing would be done at a site near Savannah, Tennessee.

Radioactive Water Leak At Fukushima Worse Than First Thought

Radiation surrounding Japan's crippled Fukushima nuclear plant has increased 18-fold following a report last month that radioactive water had leaked into the ground around the plant, which was badly damaged in a 2011 earthquake and tsunami.

Tokyo Electric Power Co., which owns the Fukushima Dai-ichi plant, reports that radiation around the site is at 1,800 millisieverts per hour, a level that Reuters says is "enough to kill an exposed person in four hours."

Previously, the utility, also known as Tepco, said the leaking water was at around 100 millisieverts per hour.

Diagnosing Self-Destruction

Suicide kills twice as many people as murder each year in the United States, and rates in the military recently surpassed those among civilians. But while scientists have identified some risk factors for suicide being white, being male, substance abuse, mental illness — they still have little idea what spurs people to take their own lives.

Space Telescope Reawakened for an Asteroid Hunt

After the WISE telescope used up the coolant needed to operate its detectors, its primary mission as an infrared survey telescope ended. NASA's Amy Mainzer describes how the agency is repurposing the dormant craft for a new three-year mission looking for near-Earth asteroids. Astronomer Brett Gladman also discusses a newly spotted asteroid-like object trailing Uranus.
