| Thickest parts of Arctic ice cap melting faster Posted: 29 Feb 2012 04:00 PM PST A new study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean's floating ice cap. |
| Earthworms to blame for decline of ovenbirds in northern Midwest forests Posted: 29 Feb 2012 11:22 AM PST A recent decline in ovenbirds, a ground-nesting migratory songbird, in forests in the northern Midwest United States is being linked by scientists to a seemingly unlikely culprit: earthworms. |
| How insects 'remodel' their bodies between life stages Posted: 29 Feb 2012 11:22 AM PST How is it that an insect can remake itself so completely that it appears to be a different creature altogether, not just once, but several times in its lifetime? Working with fruit flies scientists found that genes whose expression is induced by pulses of steroid hormone are key to these transformations. A similar mechanism may underlie puberty -- the human analog of metamorphosis. |
| Oldest fossilized forest: Entire fossil forest dating back 385 million years unearthed Posted: 29 Feb 2012 11:08 AM PST Researcher who previously found evidence of the Earth's earliest tree, has gone one step further. The research team has now unearthed and investigated an entire fossil forest dating back 385 million years. |
| When continents collide: New twist to 50-million-year-old tale Posted: 29 Feb 2012 11:06 AM PST Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau. |
| Genetics of endangered African monkey suggest troubles from warming climate Posted: 29 Feb 2012 07:52 AM PST A rare and endangered monkey in an African equatorial rainforest is providing a look into our climatic future through its DNA. Its genes show that wild drills, already an overhunted species, may see a dramatic population decline if the forest dries out and vegetation becomes sparser amid warming temperatures, researchers report. |
| Inherited epigenetics produced record fast evolution Posted: 29 Feb 2012 06:18 AM PST The domestication of chickens has given rise to rapid and extensive changes in genome function. Scientists have established that the changes are heritable, although they do not affect the DNA structure. |
| T. rex has most powerful bite of any terrestrial animal ever Posted: 28 Feb 2012 05:38 PM PST Research, using computer models to reconstruct the jaw muscle of Tyrannosaurus rex, has suggested that the dinosaur had the most powerful bite of any living or extinct terrestrial animal. |
| Posted: 28 Feb 2012 08:43 AM PST Rising sea levels are likely to change Southern California beaches in the coming century, but not in ways you might expect. While some beaches may shrink or possibly disappear, others are poised to remain relatively large -- leaving an uneven distribution of economic gains and losses for coastal beach towns, according to a new study. |
