| Shark fisheries globally unsustainable: 100 million sharks die every year Posted: 01 Mar 2013 12:32 PM PST The world's shark populations are experiencing significant declines with perhaps 100 million – or more - sharks being lost every year, according to a new study. |
| New insights into plant evolution Posted: 01 Mar 2013 09:33 AM PST New research has uncovered a mechanism that regulates the reproduction of plants, providing a possible tool for engineering higher yielding crops. |
| Saharan and Asian dust, biological particles end global journey in California Posted: 01 Mar 2013 09:33 AM PST A new study is the first to show that dust and other aerosols from one side of the world influence rainfall in the Sierra Nevada. |
| Volcanic aerosols, not pollutants, tamped down recent Earth warming Posted: 01 Mar 2013 09:30 AM PST Scientists looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight -- dozens of volcanoes spewing sulfur dioxide. |
| Living through a tornado does not shake optimism Posted: 01 Mar 2013 09:30 AM PST Even in the face of a disaster, we remain optimistic about our chances of injury compared to others, according to a new study. Residents of a town struck by a tornado thought their risk of injury from a future tornado was lower than that of peers, both a month and a year after the destructive twister. Such optimism could undermine efforts toward emergency preparedness. |
| New study reveals how sensitive US East Coast regions may be to ocean acidification Posted: 01 Mar 2013 09:30 AM PST A continental-scale chemical survey in the waters of the eastern US and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity. |
| Order in the chaos of a cell membrane Posted: 01 Mar 2013 02:16 AM PST An explanation has been proposed for the way in which ordered structures arise in cell membranes. Scientists have discovered how complex compounds of sugar and lipids -- known as glycolipids -- order themselves in cell membranes into rafts, namely small, highly organized domains. The arrangement of glycolipids on the surface of plant and animal cell membranes regulates numerous cellular processes. If errors occur in this process, diseases like PNH and BSE can arise. |
