Engineers have discovered that they can actually move deep water and create upward fountains by shining laser beams on the water's surface. The finding, credited to the Marangoni effect, has potential to impact fluid dynamics in many applications.

NASA's Curiosity rover landed on Mars on Aug. 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home for researchers to interpret. Analysis of carbon isotopes in sediment samples taken from half a dozen exposed locations, including an exposed cliff, leave researchers with three plausible explanations for the carbon's origin -- cosmic dust, ultraviolet degradation of carbon dioxide, or ultraviolet degradation of biologically produced methane.
