| Synthetic fuel could eliminate U.S. need for crude oil, researchers say Posted: 05 Dec 2012 05:02 PM PST The United States could eliminate the need for crude oil by using a combination of coal, natural gas and non-food crops to make synthetic fuel, a team of researchers has found. Besides economic and national security benefits, the plan has potential environmental advantages. Because plants absorb carbon dioxide to grow, the United States could cut vehicle greenhouse emissions by as much as 50 percent in the next several decades using non-food crops to create liquid fuels, the researchers said. |
| Extraverted gorillas enjoy longer lives, research suggests Posted: 05 Dec 2012 10:24 AM PST Gorillas with an extravert personality live longer than their more introverted peers, a study suggests. Researchers looked at the role of personality by studying 298 gorillas in North American zoos and sanctuaries for over 18 years. |
| Posted: 05 Dec 2012 10:24 AM PST Researchers have peered far back in time, to the era of the first stars and galaxies, and found matter with no discernible trace of heavy elements. |
| Posted: 05 Dec 2012 10:24 AM PST A young star no more than 300,000 years old is surrounded by a disk of dust and gas rotating in the same manner as planets in our Solar System, making it the youngest such infant system yet found. |
| Speeding up electronics to light frequencies Posted: 05 Dec 2012 10:22 AM PST New results on the interaction of femto- and attosecond light pulses with a solid insulator hold promise for reaching electronic switching rates up to the petahertz domain. |
| New genetic fingerprint lives in your gut Posted: 05 Dec 2012 10:21 AM PST Our bodies contain far more microbial genes than human genes. And a new study suggests that just as human DNA varies from person to person, so too does the massive collection of microbial DNA in the intestine. The research is the first to catalog the genetic variation of microbes that live in the gut. |
| NASA twin spacecraft create most accurate gravity map of moon Posted: 05 Dec 2012 09:43 AM PST Twin NASA probes orbiting the moon have generated the highest resolution gravity field map of any celestial body. The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon's internal structure and composition in unprecedented detail. Data from the two washing machine-sized spacecraft also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved. |
| Research identifies a way to block memories associated with PTSD or drug addiction Posted: 05 Dec 2012 09:11 AM PST New research could lead to better treatments for Post-Traumatic Stress Disorder (PTSD) and drug addiction by effectively blocking memories. The research has identified a common mechanism in a region of the brain called the pre-limbic cortex, which can suppress the recall of memories linked to both aversive, traumatic experiences associated with PTSD and rewarding memories linked to drug addiction, without permanently altering memories. |
| DNA hydrogel flows like liquid but remembers its original shape Posted: 05 Dec 2012 08:28 AM PST A new material is so soft it can flow like a liquid and then, strangely, return to its original shape. It is a hydrogel, a mesh of organic molecules with many small empty spaces that can absorb water like a sponge, and qualifies as a "metamaterial" with properties not found in nature. |
| Microchoreography: Synthetic molecule used to guide cellular 'dance' Posted: 05 Dec 2012 08:28 AM PST Researchers have used a small synthetic molecule to stimulate cells to move and change shape, bypassing the cells' usual way of sensing and responding to their environment. The experiment pioneers a new tool for studying cell movement, a phenomenon involved in everything from development to immunity to the spread of cancer. |
| New technique to deliver stem cell therapy may help damaged eyes regain their sight Posted: 05 Dec 2012 07:30 AM PST Engineers have developed a new technique for delivering stem cell therapy to the eye which they hope will help the natural repair of eyes damaged by accident or disease. This could help millions of people across the world retain – or even regain - their sight. |
| Africa's Homo sapiens were the first techies Posted: 05 Dec 2012 07:30 AM PST The search for the origin of modern human behavior and technological advancement among our ancestors in southern Africa some 70,000 years ago has taken a step closer to firmly establishing Africa, and especially South Africa, as the primary center for the early development of human behavior. |
| Great-earthquake hot spots pinpointed Posted: 05 Dec 2012 07:30 AM PST The world's largest earthquakes occur at subduction zones – locations where a tectonic plate slips under another. But where along these extended subduction areas are great earthquakes most likely to happen? Scientists have now found that regions where 'scars' on the seafloor, called fracture zones, meet subduction areas are at higher risk of generating powerful earthquakes. |
| In U.S. first, surgeons implant brain 'pacemaker' for Alzheimer's disease Posted: 05 Dec 2012 07:26 AM PST Researchers have surgically implanted a pacemaker-like device into the brain of a patient in the early stages of Alzheimer's disease, the first such operation in the United States. The device, which provides deep brain stimulation and has been used in thousands of people with Parkinson's disease, is seen as a possible means of boosting memory and reversing cognitive decline. |
| Scientists find oldest dinosaur -- or closest relative yet Posted: 05 Dec 2012 05:44 AM PST Researchers have discovered what may be the earliest dinosaur, a creature the size of a Labrador retriever, but with a five foot-long tail, that walked the Earth about 10 million years before more familiar dinosaurs like the small, swift-footed Eoraptor and Herrerasaurus. The findings mean that the dinosaur lineage appeared 10 million to 15 million years earlier than fossils previously showed. |
| Galaxy-wide echoes from the past: VLT observations identify very rare new kind of galaxy Posted: 05 Dec 2012 05:38 AM PST A new galaxy class has been identified using observations from ESO's Very Large Telescope (VLT), the Gemini South telescope, and the Canada-France-Hawaii Telescope (CFHT). Nicknamed "green bean galaxies" because of their unusual appearance, these galaxies glow in the intense light emitted from the surroundings of monster black holes and are amongst the rarest objects in the Universe. |
