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.

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

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.

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.

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

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.



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.

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.

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.

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

Federal Study of East Coast Earthquake Had to Move Fast

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.

Successful Rainwater Harvesting Systems Combine New Technology With Old Social Habits

Drawing from game theory, a biomedical engineer argues that a successful common pool resource (CPR) depends on participant behavior, which requires monitoring and management.

Scientist Puts Forth a 'Fast, Cheap' Way to Slow Global Warming

A new study of dust-like particles of soot in the air provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported.

Novel Alloy Could Produce Hydrogen Fuel From Sunlight

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.

Mysteries of Ozone Depletion Continue 25 Years After the Discovery of the Antarctic Ozone Hole

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,

Cars Could Run on Recycled Newspaper

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.

Panda Poop May Be a Treasure Trove of Microbes for Making Biofuels

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.
