  Pasadena CA (JPL) Feb 07, 2017 Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet's surface. Yet, the ancient sun was about one-third less warm and climate modelers struggle to produce scenarios that get the surface of Mars warm enough for keeping water unfrozen. A leading theory is to have a thicker carbon-dioxide atmosphere forming a greenhouse-gas blanket, helping to warm the surface of ancient Mars. However, according to a new analys ... read more |

When energy and nutrients abound, a bacterium will repair itself while synthesizing new parts to create a twin and then split, all as quickly as conditions allow. But if resources shrink, so does growth rate. The cell responds by shunting its dwindling supplies from replication to repair, shutting down processes until it's running a skeleton crew to survive. Below a crucial level, it's all over. ... more Dedicated Planet Imager Opens Its Eyes to Other Worlds New planet imager delivers first science at Keck First footage of a living stylodactylid shrimp filter-feeding at depth of 4826m |
