| Posted: 13 Nov 2012 12:13 PM PST Researchers have developed a new method that doubles the efficiency of wireless networks and could have a large impact on the mobile Internet and wireless industries. |
| Total solar eclipse, Nov. 13, 2012: Hinode to support ground-based observations Posted: 13 Nov 2012 12:13 PM PST On Nov. 13, 2012, certain parts of Earth will experience a total solar eclipse. The eclipse will only be seen from a narrow corridor in the southern hemisphere that is mostly over the ocean but also cuts across the northern tip of Australia. The JAXA/NASA Hinode mission will experience a partial eclipse of the sun near the same time as the observers in Australia. |
| Injectable sponge delivers drugs, cells, and structure Posted: 13 Nov 2012 10:43 AM PST Bioengineers have developed a gel-based sponge that can be molded to any shape, loaded with drugs or stem cells, compressed to a fraction of its size, and delivered via injection. Once inside the body, it pops back to its original shape and gradually releases its cargo, before safely degrading. |
| Even low-level radioactivity is damaging, scientists conclude Posted: 13 Nov 2012 10:42 AM PST Even the very lowest levels of radiation are harmful to life, scientists have concluded, reporting the results of a wide-ranging analysis of 46 peer-reviewed studies published over the past 40 years. Variation in low-level, natural background radiation was found to have small, but highly statistically significant, negative effects on DNA as well as several measures of health. |
| Computer memory could increase fivefold from advances in self-assembling polymers Posted: 13 Nov 2012 09:22 AM PST The researchers' technique, which relies on a process known as directed-self assembly, is being given a real-world test run in collaboration with one of the world's leading innovators in disk drives. |
| Human eye gives researchers visionary design for new, more natural lens technology Posted: 13 Nov 2012 09:20 AM PST Drawing heavily upon nature for inspiration, researchers have created a new artificial lens that is nearly identical to the natural lens of the human eye. This innovative lens, which is made up of thousands of nanoscale polymer layers, may one day provide a more natural performance in implantable lenses to replace damaged or diseased human eye lenses, as well as consumer vision products; it also may lead to superior ground and aerial surveillance technology. |
| Supersymmetry squeezed as Large Hadron Collider spots ultra rare particle decay Posted: 13 Nov 2012 06:50 AM PST Scientists at the Large Hadron Collider (LHC) at CERN, near Geneva, have spotted one of the rarest particle decays ever seen in nature. The result is very damaging to new theories like the extremely popular Supersymmetry. |
| Choreographing light: Scientists control light patterns called 'caustics' and make coherent images Posted: 13 Nov 2012 05:36 AM PST Researchers have found a way to control "caustics", the patterns that appear when light hits a water surface or any transparent material. Thanks to an elaborate algorithm, they can shape a transparent object so that it reflects an organized and coherent image. |
| Stereoscopic mammography could reduce recall rate Posted: 13 Nov 2012 05:36 AM PST A new three-dimensional digital mammography technique has the potential to significantly improve the accuracy of breast cancer screening. |
| Production of batteries made cheaper and safer, thanks to Finnish researchers Posted: 13 Nov 2012 05:35 AM PST Researchers in Finland have developed a method for producing lithium batteries that is cheaper and more environmentally friendly than previously used methods. This new process has succeeded in replacing the harmful methylpyrrolidone (NMP) solvent, which is traditionally used in the manufacturing of electrodes, with water. Removing this harmful solvent from the production process makes the production of batteries simpler and safer for employees. Production costs of batteries can be decreased by as much as 5 percent. Some of this savings comes from the reduced cost of transporting and recycling harmful chemicals and a lower risk of exposure to employees. |
| Posted: 13 Nov 2012 05:35 AM PST In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Physicists have now suggested a concept for a laser that could be powered by heat. This idea may open a completely new way for cooling microchips. |
