| Can nature parks save biodiversity? Posted: 07 Aug 2012 01:10 PM PDT As human activities put increasing pressures on natural systems and wildlife to survive, 200 scientists around the world carved up pieces of the puzzle to present a clearer picture of reality and find ways to mitigate the destructive forces at work. |
| Diseased trees new source of climate gas Posted: 07 Aug 2012 12:13 PM PDT Diseased trees in forests may be a significant new source of methane that causes climate change, according to researchers. |
| Nanoparticle discovery opens door for pharmaceuticals Posted: 07 Aug 2012 10:23 AM PDT What a student thought was a failed experiment has led to a serendipitous discovery hailed by some scientists as a potential game changer for the mass production of nanoparticles. |
| Dyslexia caused by faulty signal processing in brain; Finding offers clues to potential treatments Posted: 07 Aug 2012 07:49 AM PDT Researchers have made a major step forward in understanding the cause of dyslexia. The scientists have discovered an important neural mechanism underlying dyslexia and shown that many difficulties associated with dyslexia can potentially be traced back to a malfunction of the medial geniculate body in the thalamus. The results provide an important basis for developing potential treatments. |
| Paddlefish's doubled genome may question theories on limb evolution Posted: 07 Aug 2012 07:13 AM PDT The American paddlefish -- known for its bizarre, protruding snout and eggs harvested for caviar -- duplicated its entire genome about 42 million years ago, according to a new study. This finding may add a new twist to the way scientists study how fins evolved into limbs since the paddlefish is often used as a proxy for a more representative ancestor shared by humans and fishes. |
| Posted: 07 Aug 2012 07:13 AM PDT Babies can get sick often, but parents shouldn't take the blame. A new study shows essential immune cells that help fight infections don't develop until adulthood. |
| Astronomers crack mystery of the 'monster' stars Posted: 07 Aug 2012 07:12 AM PDT In 2010 scientists discovered four 'monster' sized stars, with the heaviest more than 300 times as massive as our Sun. Despite their incredible luminosity, these exotic objects, located in the giant star cluster R136 in the nearby galaxy the Large Magellanic Cloud; have oddly so far been found nowhere else. Now a group of astronomers have a new explanation: the ultramassive stars were created from the merger of lighter stars in tight binary systems. |
| New metamaterials device focuses sound waves like a camera lens Posted: 07 Aug 2012 06:57 AM PDT Researchers have designed and computationally tested a type of humanmade metamaterial capable for the first time of manipulating a variety of acoustic waves with one simple device. |
