Crystalline materials enable high-speed electronic function in optical fibers (University of Southampton) Scientists at the University of Southampton, in collaboration with Penn State University have, for the first time, embedded the high level of performance normally associated with chip-based semiconductors into an optical fiber, creating high-speed optoelectronic function. Materials for first optical fibers with high-speed electronic function are developed (Penn State) For the first time, researchers have developed crystalline materials that allow an optical fiber to have integrated, high-speed electronic functions. The potential applications of such optical fibers include improved telecommunications and other hybrid optical and electronic technologies, improved laser technology, and more-accurate remote-sensing devices. Researchers find social robots require astute tuning to improve acceptability by the human mind (The Kavli Foundation) The future of social robotics requires meeting the expectations of the human brain, as well as keenly respecting the subtle complexities of both verbal and nonverbal communication. Study published in Neuro-Oncology shows brain tumor eradication and prolonged survival (Canale Communications) Tocagen Inc. today announced the publication of data showing the company's investigational treatment for high grade glioma eradicates brain tumors and provides a dramatic survival benefit in mouse models of glioblastoma. Almost all mice receiving the top dose of Toca 511 followed by 5-FC were still alive at 180 days, which was the termination date for the experiment, whereas all control mice died by day 43. The article was published today in the February issue of the Neuro-Oncology journal. Fellowships to assist 9 UC Riverside students secure doctoral degrees (University of California - Riverside) The University of California, Riverside has awarded nine first-year graduate students an annual stipend of $30,000 for two years to increase underrepresented minority students in the fields of Science, Technology, Engineering and Mathematics at the doctoral level. In addition to the stipend that covers living expenses, each student's graduate tuition and fees are fully covered. Because of the fellowships, the nine students will be fully engaged in research from the outset. Surface of Mars an unlikely place for life after 600 million year drought, say scientists (Imperial College London) Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet's surface, according to researchers who have been carrying out the painstaking task of analyzing individual particles of Martian soil. Judder-free videos on the smartphone (Fraunhofer-Gesellschaft) Overloaded cellular networks can get annoying - especially when you want to watch a video on your smartphone. An optimized Radio Resource Manager will soon be able to help network operators accommodate heavy network traffic. Researchers will present their solution at the GSMA Mobile World Congress from Feb. 27 to March 1, 2012 in Barcelona (Hall 2, Booth E41). Jointly utilizing LTE networks (Fraunhofer-Gesellschaft) Data-intensive Internet applications on smartphones, tablets and laptops are more popular than ever before. The result: Traffic on the mobile network is increasing at a blinding speed. Intelligent technologies are intended to increase the data rates on the new LTE network. The solution is to use the mobile networks jointly. NASA satellites see wind shear battering Tropical Depression Iggy (NASA/Goddard Space Flight Center) NASA satellites have watched as wind shear has torn Cyclone Iggy apart over the last day. NASA infrared satellite imagery showed that Iggy's strongest thunderstorms have been pushed away from the storm's center and visible imagery shows the storm is being stretched out. Iggy is weakening and heading for a landfall between Geraldton and Perth. 'First light' taken by NASA's newest CERES instrument (NASA/Goddard Space Flight Center) The doors are open on NASA's Suomi NPP satellite and the newest version of the Clouds and the Earth's Radiant Energy System (CERES) instrument is scanning Earth for the first time, helping to assure continued availability of measurements of the energy leaving the Earth-atmosphere system.
