An eight-year study has concluded that increasingly frequent and severe drought, dropping water tables and dried-up springs have pushed some aquatic desert ecosystems into “catastrophic regime change,” from which many species will not recover.
North American forests appear to have a greater capacity to soak up heat-trapping carbon dioxide gas than researchers had previously anticipated.
New doctoral thesis documents that industrial chemicals are transported from the industrialized world to the Arctic via air and sea currents. Here, the cocktail of environmental toxins is absorbed by the sea's food chains which are so rich in fats and of which the polar bear is the top predator.
Pelican Refining Company LLC could potentially pay $12 million in criminal penalties in a plea agreement, marking the largest criminal fine in Louisiana for violations of the Clean Air Act.
Seven papers published in the current issue of Technology and Innovation, Proceedings of the National Academy of Inventors report on efforts by the U.S. Department of Energy (DOE) to ensure continued safe and secure storage and disposition of 50 years worth of spent nuclear fuel, surplus nuclear materials, and high-level wastes at DOE facilities.
The problem is stark: One billion people on earth don't have enough food right now. It's estimated that by 2050 there will be more than nine billion people living on the planet.
A University of Minnesota team of researchers has overcome a major hurdle in the quest to design a specialized type of molecular sieve that could make the production of gasoline, plastics and various chemicals more cost effective and energy efficient.
Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between plant cells. In a paper published in The Plant Cell, University of Missouri scientists report for the first time the elusive role a critical protein plays in this molecular signaling pathway that regulates phototropism in plants.
Woods Hole Oceanographic Institution (WHOI) scientists have discovered that bacterial communication could have a significant impact on the planet's climate.
Today's climate models regard organic aerosols as static carbon-based molecules, but scientists at Pacific Northwest National Laboratory and the University of California, Irvine (UCI) showed that the particles are very dynamic.
What many might consider a "dinosaur" may be the best solution for growers fighting weed resistance today, said Dean Riechers, University of Illinois associate professor of weed physiology.
While the United States has not yet seen national legislation aimed at reducing corporate carbon footprints and promoting sustainability, state and local governments across the country have begun to take bold steps in their effort to protect the environment.
A new ultra-sensitive technology which can monitor leaks from underwater gas pipelines has been developed by scientists at the University of Southampton in the UK.
The hypothesis that the Earth was completely covered in ice 635 million years ago has received a serious blow.
The scope and intensity of mercury pollution in the Great Lakes region is much greater than previously reported, but additional mercury controls should bring needed improvement.
Trends include a 170-percent increase in toxicity listings since 2006.
Researchers at the University of Montreal have developed a computer program that enables regulators to evaluate the ecological and economic tradeoffs between marine mammal conservation, whale watching and marine transportation activities in the Saint Lawrence Estuary.
Sanborn Regional School District in Kingston, N.H., has signed the world's first power purchase agreement for ultra-efficient solar hot air, which will reduce heating bills.
Drivers can now continue to keep the air-conditioning system on during the hot sunny days even when they stop the vehicle and switch off the engine. In collaboration with Green Power Industrial Ltd, Hong Kong Polytechnic University's (PolyU) Department of Electrical Engineering has developed an innovative air-conditioning system for vehicles that can turn scorching summer heat into cool air without a single drop of gasoline.
Many people in Bangladesh and other parts of Asia have been poisoned by drinking groundwater laced with arsenic—not introduced by humans, but leached naturally from sediments, and now being tapped by shallow drinking wells. In recent years, to avoid the problem, deeper wells have been sunk 500 feet or more to purer waters—but fears have remained that when deep water is pumped out, contaminated water might filter down to replace it.
