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.
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.
This is the conclusion of a study in which data from the four largest rivers in northern Germany – the Elbe, Weser, Aller and Ems – were analyzed over ten years.
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
In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well spewed oil at a rate of about 57,000 barrels a day, totaling nearly 5 million barrels of oil released from the well between April 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas
About 20 percent of untreated water samples from public, private, and monitoring wells across the nation contain concentrations of at least one trace element, such as arsenic, manganese and uranium, at levels of potential health concern, according to a new study by the U.S. Geological Survey.
Measuring the emission of greenhouse gases from croplands should take into account the crops themselves, according to new research.
An earthquake and a hurricane, all in the same week, on the same coast. Are they related?
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
With citizens’ groups seeking government regulation of foul-smelling ammonia emissions from large dairy farms, scientists reported that adding natural plant extracts to cow feed can reduce levels of the gas by one-third while reducing the need to fortify cow feed with expensive protein supplements.
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.
Output from the 10-megawatt AC project on 80 hectares of cleared land 50km southeast of Geraldton will contribute to offsetting the energy requirements of the Southern Seawater Desalination Plant.
Scientists in France have discovered that honeybees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides
Research conducted in part at the U.S. Department of Agriculture (USDA) has confirmed that in some production systems, planting potatoes in flat beds can increase irrigation water use efficiency
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.
