paper published yesterday in the peer-reviewed journal First Monday combines advanced supercomputing with a quarter-century of worldwide news to forecast and visualize human behavior, from civil unrest to the movement of individuals. The paper, titled “Culturomics 2.0: Forecasting Large-Scale Human Behavior Using Global News Media Tone in Time and Space,” uses the tone and location …
Ericsson demonstrated LTE Advanced with speeds more than 10 times faster than those currently experienced by LTE consumers in Sweden. The system, based on commercial hardware, was operating on a test frequency provided by the PTS. This enabled Ericsson to demonstrate LTE Advanced functionality such as carrier aggregation of 3 x 20MHz (60MHz aggregated) over …
As an atomic force microscope’s tip degrades, the change in tip size and shape affects its resonant frequency and that can be used to accurately measure, in real time, the change in the tip’s shape, thereby resulting in more accurate measurements and images at nanometer size scales.

The experimental realization of extended, two-dimensional sheets of silicene, the silicon counterpart of graphene, has been elusive so far. Researchers have demonstrated that such a two-dimensional, epitaxial honeycomb Si layer forms through surface segregation on a metallic zirconium diboride (ZrB2) Film grown itself epitaxially on Si(111). The honeycomb Si layer uniformly covers the ZrB2(0001) surface …
Harvard has a project to develop robotic bees The aim is to push advances in miniature robotics and the design of compact high-energy power sources; spur innovations in ultra-low-power computing and electronic “smart” sensors; and refine coordination algorithms to manage multiple, independent machines. They want to make them robust and agile enough that they might …
Significant Reduction of Thermal Conductivity in Si/Ge Core−Shell Nanowires We report on the effect of germanium (Ge) coatings on the thermal transport properties of silicon (Si) nanowires using nonequilibrium molecular dynamics simulations. Our results show that a simple deposition of a Ge shell of only 1 to 2 unit cells in thickness on a single …
Maersk Line has signed a contract for 10 of the world’s largest, most efficient container vessels with an option to buy another 20. The vessels will have a capacity of 18,000 TEU and will be delivered from Korea’s DSME shipyard from 2013 to 2015. The new, giant container vessels will be known as Triple-E, based …
This doughnut of ultracold gas spins without friction, creating a current of atoms that could be used to develop the first “atomtronic” sensors. Physicists have developed a new type of circuit that is little more than a puff of gas dancing in laser beams. By choreographing the atoms of this ultracold gas to flow as …
Researchers at Northwestern University, the Center for Integrated Nanotechnologies at Sandia and Los Alamos National Laboratories, and Binghamton University have found a way to dramatically improve the reliability of carbon nanotube-based nanoelectromechanical (NEMS) systems. Their results are published in the journal Small. * NEMS have a tendency to stick shut, burn or fracture after only …
Ad Support : Nano Technology Netbook Technology News Computer Software Chinese experts have told The Age that five provinces are set to relax the policy next year and this trial may spread nationwide by 2013 or 2014, at which point China’s working-age population will have stopped growing and the policy’s ”demographic dividend” will have become a …
