Martian Sand Dunes in Spring
NASA – Mars’ northern-most sand dunes are beginning to emerge from their winter cover of seasonal carbon dioxide (dry) ice. Dark, bare south-facing slopes are soaking up the warmth of the sun.
The steep lee sides of the dunes are also ice-free along the crest, allowing sand to slide down the dune. Dark splotches are places where ice cracked earlier in spring, releasing sand. Soon the dunes will be completely bare and all signs of spring activity will be gone.

By Morgan McCorkle – “One of the dreams is to bring home some polymer paint from the hardware store, spray it on a window and make your own solar cell because it self-orders into a structure that can generate electricity,” ORNL’s David Geohegan said.
“But right now there are many unknown things that happen when you spray it down and it dries. Changing the electrical property of a polymer also changes its structure when it dries, so understanding this process is one of our big science mysteries.”
Modeling the system through quantum calculations helped the researchers determine that heavy hydrogen changes the molecules’ vibrations, which indirectly but significantly affects the material’s electronic properties. more> http://tinyurl.com/pwbx76b

Source Region for Possible Europa Plumes
NASA – This reprojection of the official USGS basemap of Jupiter’s moon Europa is centered at the estimated source region for potential water vapor plumes that might have been detected using the Hubble Space Telescope. The view is centered at -65 degrees latitude, 183 degrees longitude.
In addition to the plume source region, the image also shows the hemisphere of Europa that might be affected by plume deposits. This map is composed of images from NASA’s Galileo and Voyager missions. The black region near the south pole results from gaps in imaging coverage.

By Michael Moran – World War I marked the true beginning of modern, mechanized warfare. The submarine, the tank, chemical weapons and armed aircraft, among many other innovations, first made their terrible mark in this war.
The results shocked the world and shook the faith of average citizens and elites.
In geopolitical terms, World War I set in motion changes that continue to remake our planet.
Amid the snow- and blood-choked battles on the Eastern Front in 1917, the Romanov dynasty [2, 3, 4, 5] that had ruled Russia for four centuries fell, ultimately to be replaced by the Bolsheviks [2, 3, 4, 5]. They laid the groundwork for a communist system that held sway throughout the Cold War. more> http://tinyurl.com/m74skzp

By Susan Decker – Google paid to license the patents at issue in those cases on its own behalf as well as its users’.
Even so, the legal assault by Beneficial, a so-called patent troll that files infringement suits in search of settlements, continued. So Google sued for breach of contract.
On Jan. 23 a jury in Marshall, Tex., agreed with the Mountain View (Calif.)-based company that the terms of the 2010 deal had been breached.
The nominal damages—$1—were more than enough in this case, since Google’s real objective was to enforce the terms of the deal and not back down. more> http://tinyurl.com/pjyzts4
