The U.S. military and law enforcement agencies have seen increased public scrutiny on the domestic use of the robotically piloted planes known as drones. Working on the sidelines of this debate, the U.S. Geological Survey has been trying to find a second life for retired military drones in the areas of environmental and wildlife management. Instead of watching the battlefield, these drones are watching birds.
A small church in Santa Fe, N.M., has grown up around a unique sacrament. Twice a month, the congregation meets in a ritualized setting to drink Brazilian huasca tea, which has psychoactive properties said to produce a trance-like state.
The Supreme Court confirmed the UDV church's right to exist in 2006. The church doesn't seek new members and prefers to keep a low profile. It did, however, agree for the first time to open up to a journalist.
When you travel, do you want to drink Bellinis in Venice and yak butter tea in Tibet? Well, so do monkeys.
Monkeys will eat new, different food if they travel to a new place and want to fit in with the locals, according to a new study. But back home, they'll eat what Mama eats, shunning perfectly good food if it doesn't get her approval.
We're going to switch gears now and tell you about a competition that is really about to take off - pun intended. We're talking about the nation's largest rocketry tournament, the Team America Rocketry Challenge.
If you think that making a model rocket is kids' stuff, listen to this: Teams must build a rocket that can fly as close to 800 feet as possible in about 45 seconds. The rockets have to carry two raw eggs into the air and bring them back safely. The top-ranked teams will compete in the national competition on May 11th.
When Superstorm Sandy inundated lower Manhattan last year, thousands of lab animals drowned and many scientists lost months or even years of work. One of those scientists is Gordon Fishell, a brain researcher at New York University.
Just hours before Sandy reached New York, Fishell says, he began to worry that animals housed in a basement below his lab were in danger. "I realized Hurricane Sandy and high tide were going to coincide at Battery Park, which is right where my lab is," he says.
Up until now, pipelines that carry tar sands oil have been treated just like pipelines that carry any other oil. But the Environmental Protection Agency now says that should change. That's because when tar sands oil spills, it can be next to impossible to clean up.
The agency made this argument in its evaluation of the State Department's environmental review of the Keystone XL pipeline project, which, if approved, would carry heavy crude from Alberta, Canada, to refineries in the United States.

Scientists have digitized and analyzed imagery taken by one of the first U.S. weather satellites to create a montage showing the extent of polar sea ice in 1964 so they can compare it to more recent satellite photos.
Last year's drought wreaked havoc on farmers' fields in much of the Midwest, cutting crop yields and forcing livestock producers to cull their herds. This spring, the rain that farmers needed so badly in 2012 has finally returned. But maybe too much, and at the wrong time.
It's almost the end of April, which is prime time to plant corn. But farmers need a break in the rain so they can get this year's crops in the ground and try to lock in good yields at harvest.
Much of our coffee comes from places where the environment is endangered and workers earn very little — sometimes, just a few dollars for a whole day's work. Coffee farmers have helped cut down tropical forests, and most of them use pesticides.
It's easy to feel dispirited about climate change because the challenge of dealing with it seems so overwhelming. But Miguel Modestino is actually excited about the challenge. He's part of a large team hoping to make an artificial leaf — a device that would make motor fuel from sunlight and carbon dioxide rather than from fossil fuels.
Nutrition labeling has been required on packaged food since 1990, and the new federal food safety law will require calorie counts to be posted for restaurant food — all in an effort to get the American public to eat healthier.
But most studies on calorie count labels show they don't do much to nudge people toward better food choices. If I want that oh-so-delicious Chunky Monkey ice cream, knowing that a half-cup serving delivers 300 calories and 18 grams of fat isn't going to stop me.
