Satellite eyes a big influence on Tropical Storm Karina

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

Ozone-depleting compound persists, NASA research shows

August 21, 2014 8:48 am | by EurekAlert! | Comments

NASA research shows Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to....

Imaging study reveals white-matter deficits in users of codeine-containing cough syrups

August 21, 2014 8:36 am | by EurekAlert! | Comments

An imaging study of chronic users of codeine-containing cough syrups (CCS) has found deficits in specific regions of brain white matter and associates these changes with increased impulsivity in CCS users. Researchers used diffusuion tensor imaging (DTI) (an MR imaging technique), coupled with fractional anisotropy, to investigate the white matter integrity of chronic CCS users....
