| Video gamers really do see more: Gamers capture more information faster for visual decision-making Posted: 11 Jun 2013 01:19 PM PDT Hours spent at the video gaming console not only train a player's hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to researchers. |
| Marks on Martian dunes may be tracks of dry-ice sleds Posted: 11 Jun 2013 11:51 AM PDT NASA research indicates hunks of frozen carbon dioxide -- dry ice -- may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go. Researchers deduced this process could explain one enigmatic class of gullies seen on Martian sand dunes by examining images from NASA's Mars Reconnaissance Orbiter (MRO) and performing experiments on sand dunes in Utah and California. |
| Black hole naps amidst stellar chaos Posted: 11 Jun 2013 11:45 AM PDT Nearly a decade ago, NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which sees higher-energy X-ray light, has taken a peek and found the black hole asleep. |
| New tasks become as simple as waving a hand with brain-computer interfaces Posted: 11 Jun 2013 11:33 AM PDT Researchers have demonstrated that when humans use brain-computer interfaces, the brain behaves much like it does when completing simple motor skills such as kicking a ball, typing or waving a hand. Learning to control a robotic arm or a prosthetic limb could become second nature for people who are paralyzed. |
| Females fend off gut diseases -- at least among mice Posted: 11 Jun 2013 09:21 AM PDT At least among mice, females have innate protection from certain digestive conditions, according to a new study. While it's tricky to draw conclusions for human health, the findings could eventually help scientists better understand and treat the millions of people suffering from inflammatory bowel diseases. |
| You're so vain: Study links social media use and narcissism Posted: 11 Jun 2013 09:21 AM PDT Facebook is a mirror and Twitter is a megaphone, according to a new study exploring how social media reflect and amplify the culture's growing levels of narcissism. |
| Posted: 11 Jun 2013 07:20 AM PDT Scientists have successfully identified animal species that can transmit more diseases to humans by using mathematical tools similar to those applied to the study of social networks like Facebook or Twitter. Their research describes how parasite-primate interactions transmit diseases like malaria, yellow fever or AIDS to humans. Their findings could make an important contribution to predicting the animal species most likely to cause future pandemics. |
| Fractal patterns spontaneously emerge during bacterial cell growth Posted: 11 Jun 2013 05:41 AM PDT Despite bacterial colonies always forming circular shapes as they grow, their cells form internal divisions which are highly asymmetrical and branched. These fractal (self-similar) patterns are due to the physical forces and local instabilities that are a natural part of bacterial cell growth, a new study reveals. The research has important implications for the emerging field of synthetic biology. |
| Sperm wars ruled by females? Females play active, pivotal role in postcopulatory processes Posted: 10 Jun 2013 04:29 PM PDT Females play a larger role in determining paternity than previously thought, say biologists. The findings have major implications for the study of sexual selection, sexual conflict and the coevolution of male and female reproductive traits. |
