| ADHD: Scientists discover brain's anti-distraction system Posted: 18 Apr 2014 11:12 AM PDT Psychologists have made a brain-related discovery that could revolutionize doctors' perception and treatment of attention-deficit disorders. This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction.  |
| 'Dressed' laser aimed at clouds may be key to inducing rain, lightning Posted: 18 Apr 2014 11:12 AM PDT The adage "Everyone complains about the weather but nobody does anything about it" may one day be obsolete if researchers further develop a new technique to aim a high-energy laser beam into clouds to make it rain or trigger lightning. Other possible uses of this technique could be used in long-distance sensors and spectrometers to identify chemical makeup.  |
| Gecko-like adhesives now useful for real world surfaces Posted: 18 Apr 2014 11:11 AM PDT The ability to stick objects to a wide range of surfaces such as drywall, wood, metal and glass with a single adhesive has been the elusive goal of many research teams across the world, but now a team inventors describe a new, more versatile version of their invention, Geckskin, that can adhere strongly to a wider range of surfaces, yet releases easily, like a gecko's feet.  |
| Impact glass from asteroids and comets stores biodata for millions of years Posted: 18 Apr 2014 11:11 AM PDT Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds.  |
| Impact of childhood bullying still evident after 40 years Posted: 17 Apr 2014 06:25 PM PDT The negative social, physical and mental health effects of childhood bullying are still evident nearly 40 years later, according to new research. The study is the first to look at the effects of bullying beyond early adulthood. Just over a quarter of children in the study (28%) had been bullied occasionally, and 15% bullied frequently -- similar to rates in the UK today. Individuals who were bullied in childhood were more likely to have poorer physical and psychological health and cognitive functioning at age 50. Individuals who were frequently bullied in childhood were at an increased risk of depression, anxiety disorders, and suicidal thoughts.  |
| Our brains are hardwired for language Posted: 17 Apr 2014 04:16 PM PDT People blog, they don't lbog, and they schmooze, not mshooze. But why is this? Why are human languages so constrained? Can such restrictions unveil the basis of the uniquely human capacity for language? New research shows the brains of individual speakers are sensitive to language universals. Syllables that are frequent across languages are recognized more readily than infrequent syllables. Simply put, this study shows that language universals are hardwired in the human brain.  |
| Thinnest membrane feasible has been produced Posted: 17 Apr 2014 11:19 AM PDT A new nano-membrane made out of the 'super material' graphene is extremely light and breathable. Not only can this open the door to a new generation of functional waterproof clothing, but also to ultra-rapid filtration. The new membrane just produced is as thin as is technologically possible.  |
| A cross-section of the universe Posted: 17 Apr 2014 09:44 AM PDT An image of a galaxy cluster gives a remarkable cross-section of the universe, showing objects at different distances and stages in cosmic history. They range from cosmic near neighbors to objects seen in the early years of the universe. The 14-hour exposure shows objects around a billion times fainter than can be seen with the naked eye.  |
| Ancient shark fossil reveals new insights into jaw evolution Posted: 16 Apr 2014 10:33 AM PDT The skull of a newly discovered 325-million-year-old shark-like species suggests that early cartilaginous and bony fishes have more to tell us about the early evolution of jawed vertebrates -- including humans -- than do modern sharks, as was previously thought. The new study shows that living sharks are actually quite advanced in evolutionary terms, despite having retained their basic 'sharkiness' over millions of years.  |
| Patients with kidney failure to get a new lease on life Posted: 14 Apr 2014 09:36 AM PDT A European research consortium has been developing a wearable artificial kidney that would make it possible for dialysis patients to lead a more full and active life while adding another 10 to 16 years to their life expectancy.  |
