Electric sparks may alter evolution of lunar soil

August 22, 2014 9:27 am | by EurekAlert! | News | Comments

The moon appears to be a tranquil place, but modeling done by University of New Hampshire (UNH) and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking....

Sunlight, not microbes, key to CO2 in Arctic

August 21, 2014 4:52 pm | by EurekAlert! | News | Comments

The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide (CO2) after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, a new study – funded by the National Science Foundation and published this week in the journal Science – concludes that sunlight and not bacteria is the key to triggering the production of CO2....

Satellite eyes a big influence on Tropical Storm Karina

August 21, 2014 9:00 am | by EurekAlert! | News | Comments

NOAA's Central Pacific Hurricane Center noted that Tropical Storm Karina's next move is based on its interaction with Tropical Storm Lowell. Lowell is positioned to the east of Tropical Storm Karina in the Eastern Pacific Ocean. Karina is still well over 1,000 miles away from Hawaii and has become almost stationary as the mammoth Tropical Storm Lowell creeps closer to it....
