| First diplodocid sauropod from South America found Posted: 14 May 2014 03:27 PM PDT The discovery of a new sauropod dinosaur species, Leinkupal laticauda, found in Argentina may be the first record of a diplodocid from South America and the youngest record of Diplodocidae in the world. |
| Antidepressant may slow Alzheimer's disease Posted: 14 May 2014 11:23 AM PDT A commonly prescribed antidepressant can reduce production of the main ingredient in Alzheimer's brain plaques, according to new research. The findings, in mice and people, support preliminary studies that evaluated a variety of antidepressants. Brain plaques are tied closely to memory problems and other cognitive impairments caused by Alzheimer's disease. Stopping plaque buildup may halt the disastrous mental decline caused by the disorder. |
| Advance brings 'hyperbolic metamaterials' closer to reality Posted: 14 May 2014 10:34 AM PDT Researchers have taken a step toward practical applications for 'hyperbolic metamaterials,' ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. |
| Posted: 14 May 2014 10:34 AM PDT The weight of water pumped from California's agricultural heartland, the Central Valley, over the past 150 years is enough to allow Earth's crust to rebound upward, raising surrounding mountain ranges, the Sierra Nevada and Coast Ranges, some six inches. Winter rains and summer pumping cause annual up and down movements that could affect earthquakes on the San Andreas Fault, which parallels the ranges. |
| Dangerous storms: Hurricanes peaking further north, typhoons further south, than in past Posted: 14 May 2014 10:34 AM PDT Powerful, destructive tropical cyclones are now reaching their peak intensity farther from the equator and closer to the poles, according to a new study. The results of the study show that over the last 30 years, tropical cyclones -- also known as hurricanes or typhoons -- are moving poleward at a rate of about 33 miles per decade in the Northern Hemisphere and 38 miles per decade in the Southern Hemisphere. |
| Magnetar formation mystery solved? Supernova explosions and dizzying spins in a binary system Posted: 14 May 2014 05:45 AM PDT Magnetars are the bizarre super-dense remnants of supernova explosions. They are the strongest magnets known in the universe — millions of times more powerful than the strongest magnets on Earth. Astronomers now believe they've found the partner star of a magnetar for the first time. This discovery helps to explain how magnetars form — a conundrum dating back 35 years — and why this particular star didn't collapse into a black hole as astronomers would expect. |
| Strongly interacting electrons in wacky oxide synchronize to compute like the brain Posted: 14 May 2014 05:43 AM PDT A new type of computing architecture that stores information in the frequencies and phases of periodic signals could work more like the human brain to do computing using a fraction of the energy of today's computers. |
| Posted: 13 May 2014 01:17 PM PDT College football players with and without a history of concussions have less volume in the hippocampal region of the brain that relates to memory and emotion, according to a new study. Moreover, the number of years of playing experience was inversely related to hippocampal volume and reaction time. |
