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.
Water shortages - already forecasted to be a big problem as the world warms - could contribute to yet more warming through a positive feedback loop.
A recent study has found that it's being damaged by human activities, and that this is only likely to get worse. Scientists are now calling for better management and conservation of entire deep-sea ecosystems.
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.
Last spring, a volcano erupted 425 kilometers (about 265 miles) off the Oregon coast and far below the surface, at Axial Seamount. No one was aware for months, now a live streaming video will monitor the underwater volcano.
New Department of Energy efficiency standards will cut the energy use of most new refrigerators by 25 percent and help save consumers money, create jobs, reduce pollution and spur innovation and investment.
With hurricane Irene barreling up the East Coast, we bring you tips for preparing for a serious hurricane, as well as what to do during and after the storm hits.
Hurricane Irene is a major hurricane, and NASA satellite data shows its diameter is now about one-third the length of the U.S. Atlantic coastline. Meanwhile, far in the eastern Atlantic Ocean a tenth tropical depression formed. One satellite image captured both storms and shows the tremendous difference in their size.
Globally, irrigation increases agricultural productivity by an amount roughly equivalent to the entire agricultural output of the U.S., according to a new University of Wisconsin-Madison study.
A new study published in the current issue of Science rebuts earlier claims that drought has induced a decline in global plant productivity during the past decade and poses a threat to global food security.
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.
Rodger Dale DeVries, 73, a resident of Jenison, Mich., has pleaded guilty to illegally importing a polar bear trophy mount in 2007 from Canada into Michigan in violation of the Marine Mammal Protection Act.
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.
Delivering more than 40 percent of the world's mail and reaching every business and residential address in America six days a week requires the dependable, ubiquitous vehicle fleet of the U.S. Postal Service.
The arrival of El Niño, which every three to seven years boosts temperatures and cuts rainfall, doubles the risk of civil wars across 90 affected tropical countries, and may help account for a fifth of worldwide conflicts during the past half-century, say the authors.
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.
Formally established just three years ago, aeroecology is the study of flying and floating organisms in the air they inhabit.
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.
Less than 2 percent of the October-July periods since 1895 have been drier than they are currently for all of Texas and many parts of New Mexico. These areas experienced either their driest or second driest October-July periods in the last 117 years. Less than six percent of the October-July periods have been drier than current conditions in southeastern Arizona.
