| 'Alien' eggs benefit mockingbirds Posted: 20 Dec 2011 04:48 PM PST Mockingbirds rarely remove the 'alien' eggs parasitic cowbirds lay in their nests because keeping them dilutes the risk of their own eggs being attacked.  |
| New tool offers unprecedented access for root studies Posted: 20 Dec 2011 02:26 PM PST Due to the difficulty of accessing root tissue in intact live plants, research of these hidden parts has always lagged behind research on the more visible parts of plants. But now: a new technology could revolutionize root research.  |
| Will Antarctic worms warm to changing climate? Posted: 20 Dec 2011 10:39 AM PST Researchers are examining tiny worms that inhabit the frigid sea off Antarctica to learn not only how these organisms adapt to the severe cold, but how they will survive as ocean temperatures increase.  |
| Forest health versus global warming: Fuel reduction likely to increase carbon emissions Posted: 20 Dec 2011 10:39 AM PST Forest thinning to help prevent or reduce severe wildfire will release more carbon to the atmosphere than any amount saved by successful fire prevention. There may be valid reasons to thin forests – such as restoration of forest structure or health, wildlife enhancement or public safety – but increased carbon sequestration is not one of them.  |
| Climate sensitivity greater than previously believed Posted: 20 Dec 2011 10:35 AM PST Many of the particles in the atmosphere are produced by the natural world, and it is possible that plants have in recent decades reduced the effects of the greenhouse gases to which human activity has given rise. One consequence of this is that the climate may be more sensitive to emissions caused by human activity than we have previously believed.  |
| Posted: 20 Dec 2011 07:26 AM PST Sensorbots are spherical devices equipped with biogeochemical sensors, that promise to open a new chapter in the notoriously challenging exploration of earth's largest ecosystem -- the ocean.  |
| Ion channel makes African naked mole-rat insensitive to acid-induced pain Posted: 20 Dec 2011 07:25 AM PST Researchers have found out why the African naked mole-rat, one of the world's most unusual mammals, feels no pain when exposed to acid. The animals have an altered ion channel in their pain receptors that is inactivated by acid and makes the animals insensitive to this type of pain.  |
| Ironing out the details of the Earth's core Posted: 20 Dec 2011 07:25 AM PST Identifying the composition of the earth's core is key to understanding how our planet formed and the current behavior of its interior. While it has been known for many years that iron is the main element in the core, many questions have remained about just how iron behaves under the conditions found deep in the earth. Now, a team led by mineral-physics researchers has homed in on those behaviors by conducting extremely high-pressure experiments on the element.  |
| Human skull is highly integrated: Study sheds new light on evolutionary changes Posted: 20 Dec 2011 07:22 AM PST Scientists studying a unique collection of human skulls have shown that changes to the skull shape thought to have occurred independently through separate evolutionary events may have actually precipitated each other.  |
