New raw, unprocessed images of Saturn’s tiny moon, Pan, were taken on March 7, 2017, by NASA’s Cassini spacecraft. The flyby had a close-approach distance of 24,572 kilometers (15,268 miles).
These images are the closest images ever taken of Pan and will help to characterize its shape and geology.

The Cassini-Huygens mission is a cooperative project of NASA, ESA (European Space Agency) and the Italian Space Agency. NASA’s Jet Propulsion Laboratory in Pasadena, California, manages the mission for the agency’s Science Mission Directorate in Washington...

A regional dust storm currently swelling on Mars follows unusually closely on one that blossomed less than 2 weeks earlier and is now dissipating, as seen in daily global weather monitoring by NASA’s Mars Reconnaissance Orbiter. Images from the orbiter’s wide-angle Mars Color Imager (MARCI) show each storm growing in the Acidalia area of northern Mars, then blowing southward and exploding to sizes bigger than the United States after reaching the southern hemisphere.

That development path is a common pattern for generating regional dust storms during spring and summer in Mars’ south...

Learning and memory depend on cells’ ability to strengthen and weaken circuits in the brain. Now, researchers at Johns Hopkins Medicine report that a protein involved in recycling other cell proteins plays an important role in this process. Removing this protein reduced mice’s ability to learn and recall information. “We see deficits in learning tasks,” says Richard Huganir, Ph.D., professor and director of the neuroscience department at the Johns Hopkins University School of Medicine.

The team also found mutations in the gene that produces the recycling protein in a few patients with intellectual disability, and those genetic errors affected neural connections when introduced into mouse brain...
