Sandhill cranes vs windmills
The current placement of wind energy towers in the central and southern Great Plains may have relatively few negative effects on sandhill cranes wintering in the region, according to a U.S. Geological Survey study published today.Midcontinental sandhill cranes are important to sporting and tourism industries in the Great Plains, an area where wind energy development recently surged. Scientists…

USGS study shows why some chemicals bio-accumulate and others don't
Researchers have figured out what makes certain chemicals accumulate to toxic levels in aquatic food webs. And, scientists have developed a screening technique to determine which chemicals pose the greatest risk to the environment.According to the study led by the U.S. Geological Survey, two traits were identified that indicate how chemicals can build up and…

Ocean currents push phytoplankton and pollution faster than thought
The billions of single-celled marine organisms known as phytoplankton can drift from one region of the world's oceans to almost any other place on the globe in less than a decade, Princeton University researchers have found.Unfortunately, the same principle can apply to plastic debris, radioactive particles and virtually any other man-made flotsam and jetsam that…

MIT finds tectonic collisions had major impact on climatic shifts
For hundreds of millions of years, Earth's climate has remained on a fairly even keel, with some dramatic exceptions: Around 80 million years ago, the planet's temperature plummeted, along with carbon dioxide levels in the atmosphere. The Earth eventually recovered, only to swing back into the present-day ice age 50 million years ago. Now geologists at…

Which trees face death in drought?
Two hundred-twenty-five million trees dead in the southwest in a 2002 drought. Three hundred million trees in Texas in 2011. Twelve million this past year in California. Throughout the world, large numbers of trees are dying in extreme heat and drought events. Because mass die-offs can have critical consequences for the future of forests and…

Educating Consumers About Buying Sustainably
Sustainability is a word tossed around much these days. But do consumers really care about buying sustainably? The answer is yes. More and more consumers are interested in sustainability, as surveys show. A 2011 consumer survey by Nielsen found that 66 percent of socially-conscious consumers cited environmental sustainability as the most important issue from a…

Microbots Could Play Key Role in Cleaning Up Our Water Systems
What if we could not only clean up the heavy metals in our water systems, but also recycle those metals and reuse them?A new study from the Institute for Intelligent Systems in Germany and the Institute for Bioengineering of Catalonia in Spain suggests that, soon, we might be doing just that.

Shift in global winds caused record flooding in the Balkans
Disastrous floods in the Balkans two years ago are likely linked to the temporary slowdown of giant airstreams, scientists found. These wind patterns, circling the globe in the form of huge waves between the Equator and the North Pole, normally move eastwards, but practically stopped for several days then — at the same time, a…

Moths in cities have learned to avoid man-made light
The globally increasing light pollution has negative effects on organisms and entire ecosystems. The consequences are especially hard on nocturnal insects, since their attraction to artificial light sources generally ends fatal. A new study by Swiss zoologists from the Universities of Basel and Zurich now shows that urban moths have learned to avoid light. The…
