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.
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.
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.
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.
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.
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.
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.
Three studies by a University of California, Davis, air-quality research group are adding to the growing body of data suggesting that very fine and ultra-fine airborne metal particles are closely linked to serious human-health problems, including heart disease.
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.
Yale University researchers have identified a key genetic gear that keeps the circadian clock of plants ticking, a finding that could have broad implications for global agriculture.
Genetic detective work by an international group of researchers may have solved a decades-long mystery of the source of a devastating tree-killing fungus that has hit six of the world's seven continents.
In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial requirements for such systems: an approximately 100 percent energy transfer efficiency.
The Disaster Recovery Log app helps you record information about damages to your home and property using text, images and audio.
The investigation team had to move fast to take samples, create maps and photograph regional damage to subsurface and infrastructure locations before Hurricane Irene made landfall August 27.
Even after many decades of studying ozone and its loss from our atmosphere miles above the Earth, plenty of mysteries and surprises remain, including an unexpected loss of ozone over the Arctic this past winter,
Scientists from the University of Kentucky (UK) and the University of Louisville (UofL) have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight.
Panda poop contains bacteria with potent effects in breaking down plant material in the way needed to tap biomass as a major new source of “biofuels” produced not from corn and other food sources, but from grass, wood chips and crop wastes, scientists reported.
Here’s one way that old-fashioned newsprint beats the Internet: Tulane University scientists have discovered a novel bacterial strain, dubbed “TU-103,” that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline.
