A team of researchers from the British Antarctic Survey stumbled upon some interesting satellite images in 2009: a trail of penguin poop that showed signs of a huge colony of emperor penguins. A team of researchers finally made it out to visit the 9,000-strong colony last December, marking the first human contact the animals had experienced.

A pristine rainforest in Ecuador sits on top of the equivalent of millions of barrels of oil. Ecuador has offered a deal to the rich countries of the world: Pay us billions of dollars, and we'll leave the rainforest untouched.

The Republican River is crucial to the agricultural economy of several states in the West and Great Plains. But as a drought drags on, Kansas says Nebraska farmers have been taking more than their fair share of the river — and have asked the Supreme Court to weigh in.

A 48-acre area in California that housed more than 200 species of birds was stripped bare by the Army Corps of Engineers, which manages the land. The Corps says the clearing was necessary to improve flood control and discourage homeless camps and drug dealing, but some are questioning whether the agency violated rules that protect wetlands and waterfowl.

Wreckage believed to be from the 2011 Japanese tsunami is washing up thousands of miles away in Alaska. The debris isn't just unsightly — it poses environmental worries for the landscape and animals. One conservationist says the problem may be worse than the Exxon Valdez oil spill.

Bathroom hand dryers used to be a hated product because they took too long to work. But a decade ago, a family-owned business in Massachusetts came out with a new product that changed the way we dry our hands.

On the deck of a 27-foot boat off the shore of Long Island, researchers are using sonar to study the sand and sediment that washed away from the system of protective barrier islands and beaches by Hurricane Sandy.

Members of China's growing middle class are eager to spend their money on luxury goods, including hardwood furniture. The growing demand has led to massive illegal logging in Cambodia.

The U.S. Fish and Wildlife may upgrade the wood stork's status from "endangered" to "threatened." But some environmentalists and the Audubon Society says that in south Florida, the bird's population is still a long way from reaching a full recovery.

Microbes can thrive in extreme environments, from inside fiery volcanoes to down on the bottom of the ocean. Now scientists have found a surprising number of them living in storm clouds tens of thousands of feet above the Earth. And those airborne microbes could play a role in global climate.
