NASA's Hubble Sees Cloudy Super-Worlds With Chance for More Clouds Baltimore MD (SPX) Jan 01, 2014 - Scientists using NASA's Hubble Space Telescope have characterized the atmospheres of two of the most common type of planets in the Milky Way galaxy and found both may be blanketed with clouds. The planets are GJ 436b, located 36 light-years from Earth in the constellation Leo, and GJ 1214b, 40 light-years away in the constellation Ophiuchus. Despite numerous efforts, the nature of the atmo ... more | |
New Studies Give Strong Boost to Binary-Star Formation Theory Charlottesville VA (SPX) Jan 01, 2014 - Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery gives strong support for one of the competing explanations for how double-star systems form. Astronomers know that about half of all Sun-like stars are members of double or multiple-star systems, b ... more | |
China to upgrade homegrown GPS to improve accuracy Beijing (UPI) Dec 30, 2013 - China says it will have 30 satellites in its Beidou navigation system by 2020 to improve accuracy to within inches to better compete with the U.S.GPS.

Large-aperture planar lens antennas with gradient refractive index Beijing, China (SPX) Jan 01, 2014 - It was recently shown that large-aperture lens antennas can be designed by using gradient-index (GRIN) metamaterials and that higher directivity and gain can be obtained than with traditional dielectric lens antennas. This provides an effective method to design high-performance lens antennas. A paper titled "Three-dimensional large-aperture lens antennas with gradient refractive index," pu ... more | |

Earth's crust was unstable in the Archean eon and dripped down into the mantle Mainz, Germany (SPX) Dec 31, 2013 - Earth's mantle temperatures during the Archean eon, which commenced some 4 billion years ago, were significantly higher than they are today. According to recent model calculations, the Archean crust that formed under these conditions was so dense that large portions of it were recycled back into the mantle. This is the conclusion reached by Dr. Tim Johnson who is currently studying the evo ... more | |
After Impressive Demonstrations of Robot Skill, DARPA Robotics Challenge Trials Conclude Homestead, FL (SPX) Dec 28, 2013 - On December 20-21, 2013, 16 teams were the main attraction at the DARPA Robotics Challenge (DRC) Trials, where they demonstrated their prototype robots' ability to perform a number of critical real-world disaster-response skills. DARPA constructed eight tasks at the Homestead Speedway in Homestead, Fla., to simulate what a robot might have to do to safely enter and effectively work inside a disa ... more | |
Only lawyers profit as tech giants go to war over patents Washington DC (UPI) Dec 29, 2013 - Technology companies have research and development departments, design staffs, factories to build their products, sales and marketing departments to convince consumers to buy them - and increasingly, it seems, lawyers to bicker and sue over patents. Two of the industry's giants - Apple and Samsung, who between them have made nearly half of the smartphones sold worldwide - have spent ... more | |
Batteries as they are meant to be seen Richland WA (SPX) Dec 28, 2013 - Researchers have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. While life sciences researchers regularly use transmission electron microscopy to study wet environments, this time scientists have applied it successfully to rechargeable battery research. The results, reported in De ... more | |
