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.
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.
Trends include a 170-percent increase in toxicity listings since 2006.
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.
As the leaves change and temps drop, the crisp autumn air brings a whole new load of waste possibilities with the new season. As opposed to the scorching summer months coupled with UV rays that dry lawns and surge kilowatts of electricity through homes for cooling, fall brings gutter clutter and leaf waste – not to mention high kilowatt usage in parts of the world prone to freezing temps.
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.
Manoa have projected an increased frequency of heavy rainfall events but a decrease in rainfall intensity during the next 30 years (2011-2040) for the southern shoreline of Oahu, according to a recent study published in the Journal of Geophysical Research.
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
This move will speed the creation of thousands of construction and operations jobs while transforming the nation’s electric system into a modern, 21st century grid that is safer and more secure, and gives consumers more energy choices.
A Californian-based study has looked in detail at air quality and the impact of traffic-related air pollution on premature birth.
Drinking water taken from a deep aquifer protected by a semi-permeable layer of rock should be protected from many contaminants, including viruses. But viruses have been discovered in many deep Madison, Wis., water wells.
Combining recently launched green technology for navigating the oceans with the need to address gaps in critical earthquake information across the globe, scientists from Scripps Institution of Oceanography at UC San Diego have been granted $1.02 million from the National Science Foundation to develop a cutting-edge deep-ocean seismic system.
In the waters along Florida’s east and west coasts, Florida State University (FSU) marine biologists are collecting new data on the once severely overfished Atlantic goliath grouper, a native species that is making a comeback in the southeastern United States after a 21-year moratorium on its capture while remaining critically endangered everywhere else in the world.
