They discovered that increases in diarrheal disease cases were closely tied to periods of rainfall, flood recession, and changes in surface water quality, with a 1 meter drop in river height in the dry season associated with a staggering 16.7 percent increase in diarrheal disease in children under 5.
But if that's the case, what is the source of the East Antarctic Ice Sheet's massive ice streams? In the course of an extensive Antarctic expedition, researchers from the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) recently investigated several lakes beneath Recovery Glacier that had been previously detected by satellite remote sensing.
The University of Cincinnati is working with the Nevada Bureau of Mines and Geology to add specific details on landslides to the state's map of known hazards.
Many of today's methods of purifying water rely on filters and chemicals that need regular replenishing or maintenance. Millions of people, however, live in areas with limited access to such materials, leading the research community to explore new options of purifying water in using plasmas. Many plasma-based approaches are expensive, but a new class of plasma devices may change that. Researchers at the have been studying a new type of plasma generator for water purification.
Water researchers have found a way to fight the 'king of poisons' that accounts for one of every 20 deaths in Bangladesh.
For sweeping drama, it's hard to beat hydropower from dams -- a renewable source of electricity that helped build much of the developed world. Yet five scientists from Michigan State University say that behind roaring cascades is a legacy of underestimated costs and overestimated value.
Decisions about whether to build, remove or modify dams involve complex trade-offs that are often accompanied by social and political conflict. A group of researchers from the natural and social sciences, engineering, arts and humanities has joined forces to show how, where and when it may be possible to achieve a more efficient balance among these trade-offs. Their work is featured in a paper published in the Proceedings of the National Academy of Sciences (PNAS).
In addition to producing oil and gas, the energy industry produces a lot of water, about 10 barrels of water per barrel of oil on average. New research led by The University of Texas at Austin has found that where the produced water is stored underground influences the risk of induced earthquakes.
Scientists at the University of Plymouth have discovered that different flow regimes and oxygen levels within the marine environment are likely to result in conflict.
Since 1991, the world's oceans have absorbed an amount of heat energy each year that is 150 times the energy humans produce as electricity annually, according to a study led by researchers at Princeton and the Scripps Institution of Oceanography. The strong ocean warming the researchers found suggests that Earth is more sensitive to fossil-fuel emissions than previously thought.
