The Cerberus Groundsnake is a Critically Endangered new species from Ecuador
March 22, 2017 12:06 PM - Pensoft Publishers

With as many as 140 species, Atractus is the most diverse snake genus in the world, even though it can be found exclusively in Central and South America. However, these colubrid ground snakes seem largely under-researched, since there have been thirty-three species discovered in the last ten years only.

Wastewater should be recognized as a valuable resource, UN says on World Water Day
March 22, 2017 12:00 PM - United Nations New Centre

In a world where the demand for water continues to grow and the resource is finite, a new United Nations report argues that wastewater, discarded into the environment every day, once treated, can help meet the needs for freshwater as well as for raw materials for energy and agriculture.

"Super sponge" promises effective toxic clean-up of lakes and more
March 22, 2017 11:43 AM - University of Minnesota

Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem, University of Minnesota College of Food, Agricultural and Natural Sciences (CFANS) Professor Abdennour Abbas and his lab team created a spongethat can absorb mercury from a polluted water source within seconds. Thanks to the application of nanotechnology, the team developed a sponge with outstanding mercury adsorption properties where mercury contaminations can be removed from tap, lake and industrial wastewater to below detectable limits in less than 5 seconds (or around 5 minutes for industrial wastewater). The sponge converts the contamination into a non-toxic complex so it can be disposed of in a landfill after use. The sponge also kills bacterial and fungal microbes.

2017 U.S. Wildfire Season Off to an Intense Start
March 21, 2017 03:59 PM - Yale Environment 360

Wildfires have consumed more than 2 million acres of U.S. land so far this year, nearly 10 times the long-term average and a punishing start to this year’s wildfire season, according to data from the National Interagency Fire Center (NIFC).

Running Delivery Trucks on Trolley Wires Isn't as Crazy as It Sounds
March 20, 2017 02:07 PM - Jack Stewart via Wired

ELECTRIC TRUCKS OFFER all the advantages of electric cars, namely, they’re greener. Trucks are a big source of the noxious emissions linked to smog and climate change. Minimizing the number of stinky, dirty diesels rumbling through town carries obvious public health benefits. But powering delivery trucks, let alone an 18-wheeler, with a big honkin’ battery simply isn’t practical. So engineers are taking another look at a century old solution: Stringing electrical cables over the road.

China's Severe Winter Haze Tied to Climate Change

China's severe winter air pollution problems may be worsened by changes in atmospheric circulation prompted by Arctic sea ice loss and increased Eurasian snowfall – both caused by global climate change.

Agricultural research looks at dugouts as absorbing carbon dioxide
March 17, 2017 08:09 AM - University of Regina

Three researchers at the University of Regina have been awarded a provincial research grant to study the role of agricultural dugouts in greenhouse gas capture.

Dr. Kerri Finlay, Dr. Peter Leavitt, Dr. Gavin Simpson of the biology department, along with Dr. Helen Baulch of the University of Saskatchewan, were recently awarded $255,030 from the Saskatchewan Ministry of Agriculture's Agriculture Development Fund.

NASA Satellite Identifies Global Ammonia "Hotspots"
March 16, 2017 02:22 PM - NASA

The first global, long-term satellite study of airborne ammonia gas has revealed “hotspots” of the pollutant over four of the world’s most productive agricultural regions. The results of the study, conducted using data from NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite, could inform the development of strategies to control pollution from ammonia and ammonia byproducts in Earth’s agricultural areas.

A University of Maryland-led team discovered steadily increasing ammonia concentrations from 2002 to 2016 over agricultural centers in the United States, Europe, China and India. Increased concentrations of atmospheric ammonia are linked to poor air and water quality.
