| 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. |
