| Engineers discover method to create upward water fountain in deep water Posted: 18 Jan 2022 03:46 PM PST 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. |
| Newly discovered carbon may yield clues to ancient Mars Posted: 17 Jan 2022 01:55 PM PST 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.
