Does Valles Marineris ring a bell? This area is known for having landslides that are among the largest and longest in the

This HiRISE image cutout shows Recurring Slope Lineae in Tivat crater on Mars in enhanced color. The narrow, dark flows descend downhill (towards the upper left). Analysis shows that the flows all end at approximately the same slope, which is similar to the angle of repose for sand. Credit: NASA/JPL/University of Arizona/USGS Dark features previously

The Earth’s magnetosphere is home to the plasma waves being studied by Yuri Shprits and colleagues.

Using observations from those satellites, Christopher Russell, a UCLA graduate student at the time, detected mysterious plasma

Ice on window (stock image).

The researchers discovered that ice grows differently on absorbent vs.

Schematic showing a new engineered surface that can repel liquids in any state of wetness.

Now, researchers at Penn State have developed the first nano/micro-textured highly slippery

Galaxies of similar size to the Sombrero Galaxy may offer astronomers their first glimpse of a pair of supermassive black holes merging. This hat-shaped galaxy is large enough that its merging black holes would yield detectable gravitational waves, but not so large that the black holes would merge too quickly.

This study, published in Nature Communications, offers an

UCI’s BedMachine ice mapping technique enabled the creation of a three-dimensional image of a portion of the northwest coast of Greenland. Ocean bathymetry is shown in blue and ice surface topography are displayed in white and orange.

Tuning into memories. Scientists mapped and read sound memories in rat brains. Credit: Courtesy of Dr. Zador, Cold Spring Harbor Laboratory, N.Y. Lights, sound, action: we are constantly learning how to incorporate outside sensations into our reactions in specific situations. In a new study, brain scientists have mapped changes in communication between nerve cells as
