Arsenic, Uranium and Other Trace Elements a Potential Concern in Private Drinking Wells

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.

Crop Performance Matters When Evaluating Greenhouse Gas Emissions

Measuring the emission of greenhouse gases from croplands should take into account the crops themselves, according to new research.

Climate Change Seems Unfavorable for Toxic Blue Algae

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

Were the East Coast Hurricane and Earthquake Related?

An earthquake and a hurricane, all in the same week, on the same coast. Are they related?

Feeding Cows Natural Plant Extracts Can Reduce Ammonia Emissions, Feeding Costs

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.

Researchers Deploy a Shocking Method of Fish Collection

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.

Air-Quality Researchers Find Troubling Health Implications for Ultrafine Particles

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 Makes First Ocean Salt Measurements

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.



Australia’s First Utility-Scale Solar Photovoltaic Project Under Way

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.

Even Low Doses of Pesticides Can Put Honeybees at Risk

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

Using Less Water is No Small Potatoes

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

Manipulating Plants' Circadian Clocks May Make All-Season Crops Possible

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.

Tree-Killing Pathogen Traced Back to California

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.

Artificial Light Harvesting Method Achieves 100 Percent Energy Transfer Efficiency

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.

Protecting Wild Species May Require Growing More Food on Less Land: Study

In parts of the world still rich in biodiversity, separating natural habitats from high-yielding farmland could be a more effective way to conserve wild species than trying to grow crops and conserve nature on the same land, according to a new study published today in the journal Science.

Up From the Depths: How Bacteria Capture Carbon in the Twilight Zone

Details are now emerging about a microbial metabolic pathway that helps solve the mystery of how certain bacteria capture carbon in the dark ocean, enabling a better understanding of what happens to the carbon that is fixed in the oceans every year.

New Technology Could Simplify Removal of Arsenic from Drinking Water

With almost 100 million people in developing countries exposed to dangerously high levels of arsenic in their drinking water and unable to afford complex purification technology, scientists today described a simple, inexpensive method for removing arsenic based on chopped up pieces of ordinary plastic beverage bottles coated with a nutrient found in many foods and dietary supplements.

Roanoke Chemical Distributor To Pay $44,000 Penalty for Safety Violations

The U.S. Environmental Protection Agency announced that a chemical distributor in Roanoke, Va., has agreed to pay a $43,967 penalty and complete more than $200,000 in safety improvements to settle alleged violations of federal environmental laws designed to protect and inform the public about hazardous chemicals.

Free Disaster Recovery App Available for Those Recovering from Hurricane Irene

The Disaster Recovery Log app helps you record information about damages to your home and property using text, images and audio.

Analysis Shows Namibia's Seals are Worth More Alive Than Dead

It reveals that, in 2008, the seal hunt generated only $513,000 – a poor comparison to seal-watching, which netted $2 million in direct tourism expenditure in the same period
