| Valley networks suggest ancient snowfall on Mars Posted: 23 Jul 2013 12:50 PM PDT Researchers have shown that some Martian valleys appear to have been caused by runoff from orographic precipitation -- moisture carried part of the way up a mountain and deposited on the slopes. The findings help to answer the question of whether water flowing on ancient Mars bubbled up from the ground or fell down from the atmosphere. |
| Purple bacteria on Earth could survive alien light Posted: 23 Jul 2013 10:45 AM PDT Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Physicists recently found that these organisms can also survive in the presence of extreme alien light. The findings show that the way in which light is received by the bacteria can dictate the difference between life and death. |
| Harvesting electricity from the greenhouse gas carbon dioxide Posted: 23 Jul 2013 10:44 AM PDT A new method for producing electricity from carbon dioxide could be the start of a classic trash-to-treasure story for the troublesome greenhouse gas, scientists are reporting. The method uses CO2 from electric power plant and other smokestacks as the raw material for making electricity. |
| Rare bushcricket's chirp as loud as a power saw Posted: 23 Jul 2013 10:43 AM PDT A recently rediscovered species of bushcricket uses elastic energy and wing movement to reach high ultrasonic frequencies involving sound levels of about 110dB – comparable to that of a power saw. |
| Scientific who's who of Bolivian mammals Posted: 23 Jul 2013 10:42 AM PDT Biologists have published a massive database of mammals occurring in Bolivia, shedding light on the poorly known yet vast wildlife diversity of this South American country. |
| Secrets of mussels' clinginess revealed Posted: 23 Jul 2013 08:36 AM PDT Understanding the strength of the shellfish's underwater attachments could enable better glues and biomedical interfaces. |
