Stabilizing precipitate growth at grain boundaries in alloys

Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded ...

2014 Arctic sea ice minimum sixth lowest on record (Update)

Arctic sea ice coverage continued its below-average trend this year as the ice declined to its annual minimum on Sept. 17, according to the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, ...

The physics of undulatory human swimming

A research team led by the University of Tsukuba created the most complete recording to date of a human swimming underwater like an eel or lamprey. Using motion-capture equipment and particle velocity monitors, the scientists ...

Remarkable squirting mussels captured on film

Cambridge researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. In spring, female mussels were seen moving to the water's edge and anchoring into the riverbed, with their back ...

Study: Loss of water in drought caused Sierra Nevada to rise

Loss of water from rocks during drought caused California's Sierra Nevada to rise nearly an inch (2.5 centimeters) in height from October 2011 to October 2015, according to a new NASA study made public Wednesday.

Study explores atmospheric impact of declining Arctic sea ice

There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores ...

Icy Moons through Cassini's Eyes

(PhysOrg.com) -- These raw, unprocessed images of Saturn's moons Enceladus, Janus and Dione were taken on March 27 and 28, 2012, by NASA's Cassini spacecraft.

NASA/NOAA water vapor animations over oceans

Knowing where water vapor is in the atmosphere is one of many factors forecasters use to identify weather features. The NASA/NOAA GOES Project has now created two new types of animations based on satellite data that indicate ...
