La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter.
University of Iowa researchers have found high levels of toxic polychlorinated biphenyls (PCBs) in the deep sediments lining the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind.
Boston University researchers have estimated that even if international efforts to limit temperature increases to 2 degrees Celcius, mean global temperatures will continue to be extreme.
Trees can reveal key information about fire events, and some trees have a lot to tell — one tree researchers examined endured 14 separate fires through its lifetime.
Restoring prairies to their native vegetation can be approached from several directions. Managers might eliminate invasive plants through use of herbicides, encourage growth of native species through seeding, or manipulate conditions to favor native species.
A pilot waste-to-energy system recently constructed by Duke University and Duke Energy garnered the endorsement of Google Inc., which invests in high-quality carbon offsets from across the nation to fulfill its own carbon neutrality goals.
Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears this week in the Springer journal Climatic Change Letters.
By looking to Mother Nature for solutions, researchers have identified a promising new binder material for lithium-ion battery electrodes that could not only boost energy storage, but also eliminate the use of toxic compounds now used in manufacturing the components.
The research, conducted by the U.S. Army Engineer Research and Development Center (ERDC), focused primarily on the gathering of root characterization and site conditions through fieldwork, and modeling of single, living trees for both slope stability analyses and seepage analyses.
In the first U.S. study to measure the real impact of building energy codes on total household energy consumption, Climate Policy Initiative (CPI) found that U.S. building energy codes have reduced household energy use and greenhouse gas emissions
Each year, more than 170 million people visit national forests for recreation. And the physical activity associated with these visits burns 290 billion food calories. That equals enough french fries laid end to end to reach the Moon and back -- twice -- according to a recent study in the Journal of Forestry.
The USGS has released an online, interactive decision support system that provides easy access to six newly-developed regional models describing how rivers receive and transport nutrients from natural and human sources to sensitive waters, such as the Gulf of Mexico.
Chemists at Tufts University's School of Arts and Sciences have developed the world's first single molecule electric motor, a development that may potentially create a new class of devices that could be used in applications ranging from medicine to engineering.
Clouds only amplify climate change, says a Texas A&M University professor in a study that rebuts recent claims that clouds are actually the root cause of climate change.
A new form of resistance to fungal disease has been discovered in oilseed rape, one of the world’s most important crops, which could hold the key to developing disease resistant crops.
At Sanford-Burnham Medical Research Institute (Sanford-Burnham), a team led by Malene Hansen, Ph.D., uses a type of worm called Caenorhabditis elegans to work out the molecular underpinnings of the aging process. In a study appearing online Sept. 8 in Current Biology, they found that two cellular processes—lipid metabolism and autophagy -- work together to influence worms' lifespan.
Scientists have successfully created synthetic crystals whose structures and properties mimic those of naturally occurring biominerals such as seashells. The findings, published in the journal Nature Materials, could be an important step in the development of high-performance materials, which could be manufactured under environmentally-friendly conditions
The earth is warming up due to rising carbon dioxide concentrations in the atmosphere. NWO-funded researchers have discovered that the increase in carbon dioxide can reduce the nuisance caused by toxic blue algae, a bacterium commonly found in swimming water throughout the Netherlands in the summer
A group of fisheries scientists from Tennessee Tech University are busy monitoring the health of the Caney Fork River by pumping electricity into the water.
NASA's Aquarius instrument has successfully completed its commissioning phase and is now "tasting" the saltiness of Earth's ocean surface, making measurements from its perch in near-polar orbit.
