| Red skies discovered on extreme brown dwarf Posted: 06 Feb 2014 05:23 AM PST A peculiar example of a celestial body, known as a brown dwarf, with unusually red skies has been discovered by a team of astronomers. |
| What makes us human? Unique brain area linked to higher cognitive powers Posted: 05 Feb 2014 06:20 PM PST Researchers have identified an area of the human brain that appears unlike anything in the brains of some of our closest relatives. |
| Tree roots in the mountains 'acted like a thermostat' for millions of years Posted: 05 Feb 2014 06:04 PM PST For the first time, scientists have discovered how tree roots in the mountains may play an important role in controlling long-term global temperatures. Researchers have found that temperatures affect the thickness of the leaf litter and organic soil layers, as well as the rate at which the tree roots grow. In a warmer world, this means that tree roots are more likely to grow into the mineral layer of the soil, breaking down rock into component parts which will eventually combine with carbon dioxide. This process, called weathering, draws carbon dioxide out of the atmosphere and cools the planet. The theory suggests that mountainous ecosystems have acted like Earth's thermostat, addressing the risk of 'catastrophic' overheating or cooling over millions of years. |
| Posted: 05 Feb 2014 11:38 AM PST A new study reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. They also imprinted a clear signature in radio waves which astronomers can now search for. The study is a major new finding about the origins of the universe. |
| Amputee feels in real-time with bionic hand Posted: 05 Feb 2014 11:37 AM PST Dennis Aabo Sørensen is the first amputee in the world to feel sensory rich information -- in realtime -- with a prosthetic hand wired to nerves in his upper arm. Sørensen could grasp objects intuitively and identify what he was touching while blindfolded. |
| Ballistic transport in graphene suggests new type of electronic device Posted: 05 Feb 2014 10:29 AM PST Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport. |
| Decriminalizing pot may land more kids in the ER Posted: 05 Feb 2014 09:55 AM PST States that decriminalized marijuana saw dramatic increases in children requiring medical intervention, although the overall number of unintentional marijuana exposures among children remained low. Researchers studied call volume to US poison centers from January 2005 through December 2011. |
| A short stay in darkness may heal hearing woes Posted: 05 Feb 2014 09:55 AM PST Call it the Ray Charles Effect: a young child who is blind learns to hear things others cannot. Researchers know that young brains are malleable enough to re-wire some circuits that process sensory information. Now researchers have shown the brains of adult mice can also be re-wired, compensating for vision loss by improving their hearing. This may lead to treatments for human hearing loss. Minimizing a person's sight for as little as a week may help improve the brain's ability to process hearing. |
| Researchers discover rare new species of deep-diving whale Posted: 05 Feb 2014 07:35 AM PST Researchers have identified a new species of mysterious beaked whale based on a study of seven animals stranded on remote tropical islands over the past 50 years. The first was found on a Sri Lankan beach in 1963. A combination of DNA analysis and physical characteristics was used to make the identification. |
| Posted: 04 Feb 2014 10:15 AM PST New research predicts that coastal regions may face massive increases in damages from storm surge flooding over the course of the 21st century. Global average storm surge damages could increase from about $10-$40 billion per year today to up to $100,000 billion per year by the end of century, if no adaptation action is taken. |
| Pain sensitivity may be influenced by lifestyle, environment, twin study suggests Posted: 04 Feb 2014 08:21 AM PST Researchers have discovered that sensitivity to pain could be altered by a person's lifestyle and environment throughout their lifetime. The study is the first to find that pain sensitivity, previously thought to be relatively inflexible, can change as a result of genes being switched on or off by lifestyle and environmental factors -- a process called epigenetics, which chemically alters the expression of genes. |
| Violent video games delay development of moral judgment in teens Posted: 04 Feb 2014 07:17 AM PST A researcher set out to discover whether there was a link between the types of video games teens played, how long they played them, and the teens' levels of moral reasoning: their ability to take the perspective of others into account. |
| Posted: 04 Feb 2014 04:39 AM PST Scientists have developed a robot that perceives environmental stimuli and learns to react to them. The scientists used the relatively simple nervous system of the honeybee as a model for its working principles. To this end, they installed a camera on a small robotic vehicle and connected it to a computer. The computer program replicated in a simplified way the sensorimotor network of the insect brain. |
| Nine steps to save waterways and fisheries identified by researchers Posted: 31 Jan 2014 06:35 AM PST The key to clean waterways and sustainable fisheries is to follow nine guiding principles of water management, says a team of Canadian biologists. |
