Asian Pollution Affects World’s Weather

April 18, 2014 12:02 pm | by Pacific Northwest National Laboratory | News | Comments

The first study that combines different scales into one model to simulate the effects of Asian pollution on the Pacific storm track has shown that the pollution can influence weather over much of the world. These results show that using multiple scales in one model greatly improves the accuracy of climate simulations.

Credit Card-sized Anthrax Detector Aids Agriculture

Satellites Can Monitor Volcanoes

April 18, 2014 12:00 pm | by Inside Science News Service, Sophie Bushwick | News | Comments

Predicting when a volcano will blow its top takes constant monitoring. Researchers are now looking to satellites as a valuable eye in the sky, since they can observe the ground around volcanoes for signs of deformation.

System Disruption May Release Huge Amounts of Methane

April 18, 2014 7:00 am | by European Association of Geochemistry | News | Comments

Researchers have shown that humic substances act as fully regenerable electron acceptors which helps explain why large amount of methane are held in wetlands instead of being released to the atmosphere. However, there are worries that if this system is disrupted it may release large amounts of methane back into the atmosphere.

Forensic Genomics Solves Sea Snail Death Mystery

April 17, 2014 12:00 pm | by UC Davis | News | Comments

In August 2011, thousands of dead red abalone washed up on the beaches of Sonoma County in Northern California. At the time, the cause was unknown. Now, scientists, using a new approach called forensic genomics, have learned that a harmful algal bloom was to blame: the causative agent Yessotoxin.

Coffee is Getting Less Green

April 16, 2014 1:13 pm | by The Univ. of Texas at Austin | News | Comments

The proportion of land used to cultivate shade grown coffee, relative to the total land area of coffee cultivation, has fallen by nearly 20 percent globally since 1996. Researchers say the global shift toward a more intensive style of coffee farming is probably having a negative effect on the environment, communities and individual farmers.
