| Dinosaurs with killer claws yield new theory about evolution of flight Posted: 14 Dec 2011 02:15 PM PST New research has revealed how dinosaurs like Velociraptor and Deinonychus used their famous killer claws, leading to a new hypothesis on the evolution of flight in birds.  |
| Alzheimer's drug candidate may be first to prevent disease progression, mouse study suggests Posted: 14 Dec 2011 01:21 PM PST A new drug candidate may be the first capable of halting the devastating mental decline of Alzheimer's disease, based on the findings of a new study.  |
| How granular materials become solid: Discovery may be boon to engineers, manufacturers Posted: 14 Dec 2011 10:58 AM PST What is it is that makes granular materials change from a flowing loose state to a "jammed," or solid, state? Researchers can now explain how granular materials are transformed when force is applied at a particular angle, a process known as shearing.  |
| Posted: 14 Dec 2011 10:57 AM PST It was the brightest and closest stellar explosion seen from Earth in 25 years, dazzling professional and backyard astronomers alike. Now, thanks to this rare discovery -- which some have called the "supernova of a generation" -- astronomers have the most detailed picture yet of how this kind of explosion happens.  |
| Disaster looms for gas cloud falling into Milky Way's central black hole Posted: 14 Dec 2011 10:57 AM PST Astronomers have observed a cloud of gas several times the mass of Earth approaching the 4.3 million solar-mass black hole at the center of the Milky Way, and calculate that it will not survive the encounter. Astronomers calculate that by 2013, the cloud will be shredded and heated, emitting X-rays. The violent event provides a unique opportunity to record a black hole disruption until now only theorized.  |
| Ability to love takes root in earliest infancy Posted: 14 Dec 2011 09:59 AM PST The ability to trust, love, and resolve conflict with loved ones starts in childhood -- way earlier than you may think. New research suggests that your relationship with your mother during the first 12 to 18 months of life predict your behavior in romantic relationships 20 years later.  |
| New method for enhancing thermal conductivity could cool computer chips, lasers and other devices Posted: 14 Dec 2011 09:59 AM PST Engineers have discovered a surprising new way to increase a material's thermal conductivity that provides a new tool for managing thermal effects in computers, lasers and a number of other powered devices.  |
| Follow your nose: Compared to Neanderthals, modern humans have a better sense of smell Posted: 14 Dec 2011 07:18 AM PST High-tech medical imaging techniques were recently used to access internal structures of fossil human skulls. Researchers used sophisticated 3-D methods to quantify the shape of the basal brain as reflected in the morphology of the skeletal cranial base. Their findings reveal that the human temporal lobes, involved in language, memory and social functions as well as the olfactory bulbs are relatively larger in Homo sapiens than in Neanderthals.  |
| Posted: 13 Dec 2011 05:33 PM PST Scientists have found that the distinctive glossiness of the buttercup flower, which children like to shine under the chin to test whether their friends like butter, is related to its unique anatomical structure.  |
| Starving orangutans might help to better understand obesity and eating disorders in humans Posted: 13 Dec 2011 05:33 PM PST New research examining how endangered Indonesian orangutans – considered a close relative to humans -- survive during times of extreme food scarcity might help scientists better understand eating disorders and obesity in humans.  |
