| Accuracy of mobile phone population mapping demonstrated Posted: 28 Oct 2014 05:24 AM PDT Population maps based on anonymous mobile phone call record data can be as accurate as those based on censuses, an international team of researcher has demonstrated. Their findings show maps made using mobile records are detailed, reliable and flexible enough to help inform infrastructure and emergency planners; particularly in low income countries, where recent population density information is often scarce. |
| Citizen science network produces accurate maps of atmospheric dust Posted: 27 Oct 2014 09:03 AM PDT Measurements by thousands of citizen scientists in the Netherlands using their smartphones and the iSPEX add-on are delivering accurate data on dust particles in the atmosphere that add valuable information to professional measurements. The research team analyzed all measurements from three days in 2013 and combined them into unique maps of dust particles above the Netherlands. The results match and sometimes even exceed those of ground-based measurement networks and satellite instruments. |
| Organizational needs often forgotten in developing countries’ IT education Posted: 27 Oct 2014 05:53 AM PDT A shortage of skilled IT service management professionals constitutes an obstacle for the efficient use of information and communication technology, and is a particular challenge for the least developed countries, such as Tanzania. Tanzanian universities offer a high level of education in, for example, computer science and software design, but not in information technology. |
| Record data transmission over a specially fabricated fiber demonstrated Posted: 27 Oct 2014 05:52 AM PDT Researchers report the successful transmission of a record high 255 Terabits/s over a new type of fibre allowing 21 times more bandwidth than currently available in communication networks. This new type of fiber could be an answer to mitigating the impending optical transmission capacity crunch caused by the increasing bandwidth demand. |
| Breakthrough in molecular electronics paves way for new generation of DNA-based computer circuits Posted: 26 Oct 2014 04:52 PM PDT Scientists have announced a significant breakthrough toward developing DNA-based electrical circuits. Molecular electronics, which uses molecules as building blocks for the fabrication of electronic components, has been seen as the ultimate solution to the miniaturization challenge. However, to date, no one has actually been able to make complex electrical circuits using molecules. Now scientists report reproducible and quantitative measurements of electricity flow through long molecules made of four DNA strands, signaling a significant breakthrough towards the development of DNA-based electrical circuits. |
