Building huge turbine farms too close together might significantly reduce their power, some atmospheric scientists say. The problem is "wind shadow" — the turbulence created by one big cluster of turbines that steals wind from another cluster down the road.

World-famous primatologist Jane Goodall has admitted to plagiarizing several passages in her upcoming book, Seeds of Hope. It's not yet clear if Goodall or her co-author Gail Hudson is responsible for the lifted passages.

A giant reservoir of natural gas lies under the ocean floor, and no one had successfully extracted it until this week. Japanese engineers pulled it up through a well from under the Pacific. But there are still lots of unanswered questions about the viability of this new gas supply.

In the past 100 years, average temperatures on Earth have changed by 1.3 degrees. Previously, that large of a swing took 5,000 years. That's the word from researchers who pored over temperature data going back to the end of the last ice age.

Forest elephants in central Africa are being slaughtered in record numbers for their ivory tusks, a decade-long study finds. The U.S. government and wildlife advocacy groups are struggling to slow the killings as poaching is overcoming laws and treaties intended to protect the species.

Forest elephants in central Africa are being slaughtered in record numbers. The most comprehensive study ever, done over a decade, shows that poaching — mostly for the Asian market for ivory — has put the forest elephant on the brink of extinction. Poaching has overcome laws and treaties to protect the species. The U.S. government and wildlife groups are struggling to slow the killing. A meeting in March of the Convention on International Trade in Endangered Species will focus on solutions. Audie Cornish talks to Christopher Joyce.

In the wake of Superstorm Sandy, New Yorkers, local politicians and scientists face a tough decision: How to spend limited funds to defend themselves in a world where climate change is making flooding from coastal storms ever more likely.

The small projectile points seem to be 14,500 years old, the oldest direct evidence of people in America. The weapons appear to be as old or older than points made by the Clovis, who were thought to be the first in the Americas.

Industry has ruined a lot of Pennsylvania's water. Coal mining companies hammered the state, leaving behind acidic water that turned thousands of miles of streams into dead zones. People in the state are looking for ways to make sure the fracking boom doesn't deal another blow to its water.

Tiny particles from power plants and fires help create new clouds, which shade the oceans from the sun. This means changes in sea-surface temperatures. And that has profound effects on weather, influencing the time and amount of rainfall in West Africa, and even the number, strength and path of hurricanes.

The Florida Everglades is infested with Burmese pythons. To keep them from spreading, the U.S. Fish and Wildlife Service is making it illegal to import the pythons into the country, or transport them across state lines. Scientists have discovered the pythons are doing more damage than ever imagined.

The Kemp's ridley sea turtle, which hopped a ride aboard floating seaweed, made the 4,600 mile journey from the Gulf of Mexico to the shores of Portugal in 2008. Nicknamed Johnny Vasco de Gama, after the Portugese explorer, the now-rehabilitated turtle will be reintroduced into Gulf waters Tuesday.

The basic idea is to have rich countries that emit lots of climate-warming gases pay poorer countries to keep their forests, or even expand them. That's because forests suck carbon from the atmosphere. But there's not yet a global system to make a plan like this work.

The depths of our oceans are dark, punishingly cold and utterly devoid of life. Or so scientists thought, until a team of researchers in the late 1970s stumbled upon squishy, rubbery worms, up to 7 feet long, living 8,000 feet below the surface of the Pacific.
