#icymi Dark narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water # on contemporary Mars. The streaks are roughly the length of a football field.  The imaging and topographical information in this processed false-color view come from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.  These dark features on the slopes are called "recurring slope lineae" or RSL. Planetary scientists…

21 Amazing Scientific and Technological Breakthroughs That Happened Last Year

In 2014 a giant salamander emerged from the Kamo River in Japan. Landed appearances of the giant creature are considerably rare due to them making their home underwater and being only active at night. Japanese giant salamanders are the second-largest salamanders on Earth, surpassed only by the closely related Chinese giant salamander. They feed on insects, frogs, crabs, shrimp, and fish; but since the 1950s, their population has declined rapidly due to habitat destruction and overhunting.
