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.
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.
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.
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.
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.
The Disaster Recovery Log app helps you record information about damages to your home and property using text, images and audio.
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
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.
Drawing from game theory, a biomedical engineer argues that a successful common pool resource (CPR) depends on participant behavior, which requires monitoring and management.
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.
Results from the first study of the Asian longhorned beetle (ALB) in forests show that the invasive insect can easily spread from tree-lined city streets to neighboring forests.
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.
Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and eight times tougher and more durable than currently used blade materials.
Labor Day is coming, with the chance to get in one last weekend of watersports fun before fall and winter make the lake off-limits. Make sure you stay safe for next year's boat season with these tips.
New research shows that wastewater recycling processes may generate more greenhouse gases than traditional water-treatment processes. Despite this finding, there are good reasons to continue keep wastewater recycling among the water-resource tools for urban areas
Satellite views of the Midwestern United States show that ozone levels above 50 parts per billion (ppb) along the ground could reduce soybean yields by at least 10 percent, costing more than $1 billion in lost crop production, according to U.S. Department of Agriculture (USDA) scientists.
Many energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn. They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.
