NASA finds wind shear affecting Tropical Storm Josephine

NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of Tropical Storm Josephine east of the Lesser Antilles island chain. Suomi NPP revealed that Josephine was being affected by wind shear.

NASA finds wind shear making Tropical Depression 10E struggle

NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of a struggling Tropical Depression 10E in the Eastern Pacific Ocean. Wind shear is preventing the storm from intensifying into a tropical storm.

NASA finds a wispy, wind-sheared Tropical Depression 06W

NASA's Terra satellite revealed that a wispy looking Tropical Depression 06W in the Northwestern Pacific Ocean was being battered by wind shear. That wind shear is not expected to wane and the storm is expected to weaken.

Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...

Cloudsat takes a slice from tropical storm Isaias

NASA's CloudSat passed over Tropical Storm Isaias as it was strengthening back into a hurricane on Aug. 3, and before it made landfall in North Carolina. CloudSat revealed areas of heavy rain and ice particles in high, powerful ...
