| Earliest known iron artifacts come from outer space Posted: 19 Aug 2013 05:24 PM PDT Researchers have shown that ancient Egyptian iron beads held at the UCL Petrie Museum were hammered from pieces of meteorites, rather than iron ore. The objects, which trace their origins to outer space, also predate the emergence of iron smelting by two millennia. |
| LSD and other psychedelics not linked with mental health problems Posted: 19 Aug 2013 03:53 PM PDT The use of LSD, magic mushrooms, or peyote does not increase a person's risk of developing mental health problems, according to an analysis of information from more than 130,000 randomly chosen people, including 22,000 people who had used psychedelics at least once. The researchers found no link between the use of psychedelic drugs and a range of mental health problems. Instead they found some significant associations between the use of psychedelic drugs and fewer mental health problems. |
| Computer can read letters directly from the brain Posted: 19 Aug 2013 11:16 AM PDT By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this way, researchers have succeeded in determining which letter a test subject was looking at. |
| Global sea level rise dampened by Australia floods Posted: 19 Aug 2013 11:16 AM PDT When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by shows that three atmospheric patterns drove so much precipitation over Australia in 2010 and 2011 that the world's ocean levels dropped measurably. |
| Waking up to a new year: Exoplanet orbits its star in 8.5 hours Posted: 19 Aug 2013 09:19 AM PDT In the time it takes you to complete a single workday, or get a full night's sleep, a small fireball of a planet 700 light-years away has already completed an entire year. Researchers have discovered an Earth-sized exoplanet named Kepler 78b that whips around its host star in a mere 8.5 hours -- one of the shortest orbital periods ever detected. |
| Tiny fish make 'eyes' at their killer Posted: 19 Aug 2013 07:27 AM PDT Small prey fish can grow a bigger 'eye' on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new research has found. Researchers have made a world-first discovery that, when constantly threatened with being eaten, small damsel fish not only grow a larger false 'eye spot' near their tail -- but also reduce the size of their real eyes. |
| Altruism or manipulated helping? Altruism may have origins in manipulation Posted: 19 Aug 2013 06:02 AM PDT Manipulation is often thought of as morally repugnant, but it might be responsible for the evolutionary origins of some helpful or altruistic behavior, according to a new study. |
| Quadcopter piloted by a smartphone Posted: 19 Aug 2013 06:01 AM PDT A new quadcopter can negotiate its way through a room completely on its own. It does not need any human interference, and in contrast to other models, it is not assisted by any external computer. All the necessary computing power in on board; the image processing is done by a standard smartphone. |
