NASA Spots a Diminished, but Drenching Ex-Tropical Cyclone Don
Tropical Storm Don didn't live long before it weakened to a remnant low pressure area in the North Atlantic Ocean. Before it weakened NASA-NOAA's Suomi NPP satellite captured a visible image of the storm on its approach to the Windward Islands. The GPM satellite analyzed the storm's rainfall as it developed and moderate to heavy…

Pangolins at 'huge risk' as study reveals dramatic increases in hunting across Central Africa
The hunting of pangolins, the world’s most illegally traded mammal, has increased by 150 percent in Central African forests from 1970s to 2014, according to a new study led by the University of Sussex.

New USGS Filter Removes Phosphorus from Waste Water
A tabletop water filter demo designed to remove phosphorus from waste water has in five-years grown into a fully functional water treatment system capable of filtering more than 100-thousand gallons per day.Designed by a small U.S. Geological Survey team, this cost-effective and environmentally friendly water filter system uses discarded mining byproducts, called mine drainage ochre,…

Developing new technology for cheaper biofuel
PhD chemistry student Leila Dehabadi has developed a new way to separate water from ethanol, the key component in alcoholic beverages and biofuel, using starch-based materials such as corn. The method could reduce costs because it doesn’t involve using additional energy to isolate the ethanol.“Compared to distillation, this new approach based on green chemistry and engineering…

Finding leaks while they're easy to fix
Access to clean, safe water is one of the world’s pressing needs, yet today’s water distribution systems lose an average of 20 percent of their supply because of leaks. These leaks not only make shortages worse but also can cause serious structural damage to buildings and roads by undermining foundations.Unfortunately, leak detection systems are expensive…

Key to Speeding Up Carbon Sequestration Discovered
Scientists at Caltech and USC have discovered a way to speed up the slow part of the chemical reaction that ultimately helps the earth to safely lock away, or sequester, carbon dioxide into the ocean. Simply adding a common enzyme to the mix, the researchers have found, can make that rate-limiting part of the process…

New assessment identifies global hotspots for water conflict
More than 1,400 new dams or water diversion projects are planned or already under construction and many of them are on rivers flowing through multiple nations, fueling the potential for increased water conflict between some countries.A new analysis commissioned by the United Nations uses a comprehensive combination of social, economic, political and environmental factors to…

Ozone Pollution Connected to Cardiovascular Health
Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults.These findings, by a team from Duke University, Tsinghua University, Duke Kunshan University and Peking University, appear in the…

Harnessing the right amount of sunshine
Photosynthesis, which allows energy from the sun to be converted into life-sustaining sugars, can also be hazardous to green plants. If they absorb too much sunlight, the extra energy destroys their tissue.To combat this, green plants have developed a defense mechanism known as photoprotection, which allows them to dissipate the extra energy. Researchers from MIT…

Unbalanced wind farm planning exacerbates fluctuations
The expansion of renewable energy has been widely criticised for increasing weather-dependent fluctuations in European electricity generation. A new study shows that this is due less to the variability of weather than from a failure to consider the large-scale weather conditions across the whole continent: many European countries are unilaterally following national strategies to expand…
