A piece of the quantum puzzle Posted: 12 Nov 2014 11:48 AM PST Scientists have been exploring qubits (quantum bits) for quantum simulation. In this work, researchers have demonstrated a quantum version of Gauss's law. The novelty of the experiment is how the curvature was measured.

Latest supercomputers enable high-resolution climate models, truer simulation of extreme weather Posted: 12 Nov 2014 11:48 AM PST Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, scientists were able to complete a run in just three months. What they found was that not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.

Software models more detailed evolutionary networks from genetic data Posted: 12 Nov 2014 10:21 AM PST Computer scientists have developed software to build more accurate evolutionary networks from genomic data sets. A "maximum likelihood" method allows PhyloNet to infer network models that better describe the evolution of certain groups of species than do tree models.

Stock market models help researchers predict animal behavior Posted: 12 Nov 2014 09:01 AM PST Modeling used to forecast fluctuations in the stock market has been discovered to predict aspects of animal behavior. The movement of zebrafish when mapped is very similar to the stochastic jump process, a mathematical model used by financial engineers. The model could improve the effectiveness of experiments, minimize the number of fish used, and allow researchers to make better use of their data following experiments.

Virtual reality speeds up rehabilitation: Integrating force feedback into therapies for impaired hands Posted: 12 Nov 2014 06:30 AM PST A novel training program uses haptic technology for impaired hands that cannot function normally. This program is unique as it provides force feedback, which creates a true sense of weight to the user through the control device.

Electric cars without drivers Posted: 12 Nov 2014 05:41 AM PST E-Mobile will park independently in the future and will also be able to find the next charging station without a driver. Researchers are working on electric cars that can travel short distances autonomously. On the basis of cost-effective sensors, they are developing a dynamic model that perceives the environmental situation.

The great digital divide in healthcare: Older Americans may be left behind Posted: 12 Nov 2014 05:38 AM PST When it comes to the benefits of electronic health records, older Americans may be left behind, new study says. Less than a third of Americans age 65 and over use the Web for health information and barely 10 percent of those with low health literacy -- or ability to navigate the health care system -- go online for health-related matters, according to the nationally-representative study.

Cell phone habits of college students in US, South Korea studied Posted: 07 Nov 2014 10:49 AM PST The cell phone habits of 1,600 college students in the US and South Korea have been the focus of recent study by researchers who determined that mobile media is standardizing communications across the globe. The study found that students were turning more to their mobile phones to find information rather than to traditional media.
