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.
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
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.
The distant region beyond Saturn is too cold for liquid water, a necessity for life as we know it. New research indicates that rocky planets far from their parent star could generate enough heat to keep water flowing - if their atmospheres were made up primarily of hydrogen.
Corals like this one in the Florida Keys experienced unprecedented mortality rates during the severe cold snap in 2010, according to a new study published in PLoS ONE.
Oil well control is one of the most important processes during drilling operations. In deepwater drilling, controlling pressure in the oil well is crucial, as excessive pressures in the drilled hole can result in blowouts, leading to disastrous events like the 2010 Gulf of Mexico Oil Spill.
In July, at the Association for Computing Machinery’s MobiSys conference, researchers from MIT and Princeton University took the best-paper award for a system that uses a network of smartphones mounted on car dashboards to collect information about traffic signals and tell drivers when slowing down could help them avoid waiting at lights.
A University of Alberta study is sounding a warning about forestry practices in North America, claiming that climate change is already rendering established planting guidelines obsolete.
The same University of Washington researcher who used chemical sleuthing to deduce what’s in fragranced consumer products now has turned her attention to the scented air wafting from household laundry vents.
Baylor University environmental researchers have proposed in a new study a different approach to predict the environmental safety of chemicals by using data from other similar chemicals.
The U.S. Environmental Protection Agency recently announced that the Great Lakes Restoration Initiative is setting aside approximately $6 million for federal agencies to sign up unemployed workers to implement restoration projects in federally-protected areas, on tribal lands and in Areas of Concern in the Great Lakes basin.
Imagine being able to get the equivalent of 70 miles per gallon in your car, keep your home cool and power your computer – all from sewage. Thanks to technology developed by University of California-Irvine’s National Fuel Cell Research Center and partners, that’s now possible.
Findings, published online this week in the journal Air Quality, Atmosphere and Health, show that air vented from machines using the top-selling scented liquid laundry detergent and scented dryer sheet contains hazardous chemicals, including two that are classified as carcinogens
Gotham Greens, a hydroponics greenhouse facility, sits on a warehouse rooftop and brings new meaning to the phrase "locally grown" – especially atop a 15,000-square-foot manufacturing building in Greenpoint, Brooklyn.
