NASA sees Tropical Storm Enrique enter cooler waters, weaken

Tropical cyclones need sea surface temperatures of at least 80 degrees Fahrenheit (26.6 Celsius) to maintain strength, and a new infrared image from NASA's Aqua satellite shows that Tropical Storm Enrique has moved into an ...

A new look at surface chemistry

For the first time in the long and vaunted history of scanning electron microscopy, the unique atomic structure at the surface of a material has been resolved. This landmark in scientific imaging was made possible by a new ...

NASA's SDO sees two coronal holes

NASA's Solar Dynamics Observatory, or SDO, captured this solar image on March 16, 2015, which clearly shows two dark patches, known as coronal holes. The larger coronal hole of the two, near the southern pole, covers an estimated ...

Hydrocarbon photocatalysts get in shape and go for gold

A combination of semiconductor catalysts, optimum catalyst shape, gold-copper co-catalyst alloy nanoparticles and hydrous hydrazine reducing agent enables an increase of hydrocarbon generation from CO2 by a factor of ten.

A new way to view Titan: 'Despeckle' it

During 10 years of discovery, NASA's Cassini spacecraft has pulled back the smoggy veil that obscures the surface of Titan, Saturn's largest moon. Cassini's radar instrument has mapped almost half of the giant moon's surface; ...
