| Researchers identify brain network with mapping technique Posted: 18 Jul 2014 06:50 PM PDT A new image-based strategy has been used to identify and measure placebo effects in randomized clinical trials for brain disorders. The researchers used a network mapping technique to identify specific brain circuits underlying the response to sham surgery in Parkinson's disease patients.       |
| Economic development not the only influence on personal car use Posted: 18 Jul 2014 10:15 AM PDT Although countries with high levels of economic development generally have more personal automobile travel than less-affluent nations, income is not the only factor that determines a nation's demand for cars, according to a new study.  |
| Highly charged ions: Multiply-ionized atoms for clocks, qubits, and constants Posted: 18 Jul 2014 10:15 AM PDT Why can't neodymium be more like tin? Well it can, if you ionize it enough. Why strip atoms of a dozen or more electrons? To make them more amenable for use in atomic clocks and quantum computers.  |
| Improving driver safety: How to prevent streetlight glare in the new world of LED lighting Posted: 18 Jul 2014 10:15 AM PDT As energy-efficient LED lighting becomes more common along roads, scientists are looking for ways to ensure the safety of drivers by assessing the eyestrain associated with glare from the new lights. Scientists report on a model that can predict the level of discomfort experienced by drivers under various lighting conditions -- which could, ultimately, guide streetlight placement and design.  |
| Future electronics may depend on lasers, not quartz Posted: 17 Jul 2014 03:05 PM PDT Nearly all electronics require devices called oscillators that create precise frequencies -- frequencies used to keep time in wristwatches or to transmit reliable signals to radios. For nearly a century, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. A new approach could ultimately replace the quartz crystal frequency reference -- technology in use since the 1920s.  |
| Posted: 17 Jul 2014 11:20 AM PDT Researchers have developed the first ab initio method for characterizing the properties of 'hot carriers' in semiconductors. This should help clear a major road block to the development of new, more efficient solar cells.  |
| Hundreds of videos used to reconstruct 3-D motion without markers Posted: 17 Jul 2014 09:49 AM PDT Researchers have developed techniques for combining the views of 480 video cameras mounted in a two-story geodesic dome to perform large-scale 3D motion reconstruction, including volleyball games, the swirl of air currents and even a cascade of confetti.  |
| Improving the cost and efficiency of renewable energy storage Posted: 17 Jul 2014 06:49 AM PDT Scientists have developed a method for improving the catalysis of water-splitting reactions used for storing wind and solar energy. The method chemically peels off the outermost surface of a catalyst, thereby maximizing its active surface for the reaction.  |
