| Natural gas and wind are the lowest-cost generation technologies for much of the U. S. Posted: 11 Dec 2016 06:31 PM PST Natural gas and wind are the lowest-cost technology options for new electricity generation across much of the U.S. when cost, public health impacts and environmental effects are considered, according to new research.      |
| Hydrogen from sunlight -- but as a dark reaction Posted: 09 Dec 2016 03:49 PM PST The storage of photogenerated electric energy and its release on demand are still among the main obstacles in artificial photosynthesis. One of the most promising, recently identified photocatalytic new materials is inexpensive graphitic carbon nitride. Scientists have now explored a modified form that can produce light-generated electrons and store them for catalytic hydrogen production even after the light has been switched off. |
| Exploring the evolutionary history of the immune system Posted: 09 Dec 2016 03:48 PM PST Researchers have found that human ALOX15 appears to have developed a much higher capacity to stimulate the production of these lipid mediators than the enzyme variant found in lower primates. |
| Neurosurgeons harness 3-D technology to map brain during surgery Posted: 09 Dec 2016 09:58 AM PST Neurosurgeons have begun using a high-definition imaging device to see inside the brain during surgery, allowing them to map safer pathways to reach and remove tumors. The device, called Brightmatter Guide, works like a GPS, providing real-time, brightly colored 3-D images. |
| Improving the mechanical properties of polymer gels through molecular design Posted: 09 Dec 2016 08:19 AM PST A research team has developed new approach to strengthen polymer gels by changing the length of polymer "thread" per molecular "bead". |
| Sand absorbs high-speed ballistic impact better than steel Posted: 09 Dec 2016 05:06 AM PST Scientists have found that when a projectile is fired at a sand block at high speed, it absorbs more than 85 per cent of the energy exerted against it. This ability to resist the impact increases with the speed of the projectile, even at high velocities. |
| Moderate exercise improves memory dysfunction caused by type 2 diabetes Posted: 09 Dec 2016 05:06 AM PST Researchers show that moderate exercise may improve hippocampal memory dysfunction caused by type 2 diabetes and that enhanced transport of lactate to neurons may be the underlying mechanism. |
