| California blue whales rebound from whaling; first of their kin to do so Posted: 05 Sep 2014 06:02 AM PDT The number of California blue whales has rebounded to near historical levels and, while the number of blue whales struck by ships is likely above allowable U.S. limits, such strikes do not immediately threaten that recovery. |
| Archerfish target shoot with 'skillfully thrown' water Posted: 04 Sep 2014 10:15 AM PDT Archerfish hunt by shooting jets of water at unsuspecting prey on leaves or twigs above, knocking them into the water below before gobbling them up. Now, a study finds that those fish are much more adaptable and skillful target-shooters than anyone had given them credit for. The fish really do use water as a tool making them the first known tool-using animal to adaptively change the hydrodynamic properties of a free jet of water. |
| How the brain finds what it's looking for Posted: 04 Sep 2014 10:11 AM PDT A brain region that appears central to perceiving the combination of color and motion has been identified by researchers. These neurons shift in sensitivity toward different colors and directions depending on what is being attended. The study sheds light on a key neurological process. |
| 'Brightpoints': New clues to determining the solar cycle Posted: 03 Sep 2014 07:47 AM PDT Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. However, the timing of the solar cycle is far from precise. Now, researchers have discovered a new marker to track the course of the solar cycle -- brightpoints, little bright spots in the solar atmosphere that allow us to observe the constant roiling of material inside the sun. |
