This image, using data from NASA's Galileo mission, shows the first detection of clay-like minerals on the surface of Jupiter's moon Europa.

This mosaic of images from the Mast Camera (Mastcam) instrument on NASA's Curiosity Mars rover shows a series of sedimentary deposits in the Glenelg area of Gale Crater, from a perspective in Yellowknife Bay looking toward west-northwest.

The ability to sort carbon nanotubes by type through a process called “density gradient ultracentrifugation (DGU)” allowed Rice researchers to test purified batches of nanotubes to find the cause of terahertz peaks in spectroscopic experiments. They determined that free electrons formed plasmons that ripple at terahertz frequencies in metallic and doped nanotubes.

Spatial distribution of snow water equivalent across the Tuolumne River Basin from April 10 to June 1, 2013 as measured by NASA's Airborne Snow Observatory.

The novel small molecule compounds readily form nanofibers with strong antifungal capability.

As ice at the North Pole disappears at an alarming rate, some researchers are finding a link between that phenomenon and recent bouts of extreme weather. A new study suggests rapid warming in the Arctic may be altering weather patterns across the Northern Hemisphere, but skeptics say the case is far from proven.
