Diabetic eye screenings via telemedicine show value for underserved communities

Thu, 11/13/2014 - 21:19
Eye screenings via telemedicine of people with diabetes in underserved communities revealed that one in five had early stage diabetic retinopathy, according to a new study. The findings also indicated that nearly half of the mostly minority populations screened had additional vision conditions such as glaucoma or cataract.

Self-repairing software tackles malware

Thu, 11/13/2014 - 19:00
Computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer again.

Cats and athletes teach robots how to fall

Thu, 11/13/2014 - 17:32
Scientists are studying mid-air orientation and impact behavior in both cats and humans as it applies to reduced impact in falling robots, especially those that one day may be used for search-and-rescue missions in hazardous conditions.

Software to automatically outline bones in x-rays

Thu, 11/13/2014 - 16:00
Research into disorders such as arthritis will be helped by new software that automatically outlines bones – saving thousands of hours of manual work. "The idea of this software is to take the routine tasks out of human hands, so scientists can focus on drawing conclusions and developing treatments," developers said.

New way to move atomically thin semiconductors for use in flexible devices

Thu, 11/13/2014 - 13:52
Researchers have developed a new way to transfer thin semiconductor films, which are only one atom thick, onto arbitrary substrates, paving the way for flexible computing or photonic devices.

Use of private social media affects work performance

Thu, 11/13/2014 - 13:51
The use of online social media for personal purposes during working hours can have a negative effect on work performance and the well-being of organizations, research indicates. Every day, more than one billion people worldwide use social media. This habit has also invaded the workplace, as some research reports that four out of five employees use social media for private purpose during working hours, authors note.

A piece of the quantum puzzle

Wed, 11/12/2014 - 19:48
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.

Fighting crime through crowdsourcing: Researchers are looking at using crowdsourcing to help in facial recognition

Wed, 11/12/2014 - 19:48
Researchers are developing a computing model that uses crowdsourcing to combine and optimize human efforts and machine computing elements. The new model can be used to efficiently perform the complex tasks of face recognition -- a method used in law enforcement.

Latest supercomputers enable high-resolution climate models, truer simulation of extreme weather

Wed, 11/12/2014 - 19:48
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.

Virtual reality helps people to comfort, accept themselves

Wed, 11/12/2014 - 19:48
Self-compassion can be learned using avatars in an immersive virtual reality, finds new research. This innovative approach reduced self-criticism and increased self-compassion and feelings of contentment in naturally self-critical individuals. The scientists behind the study say it could be applied to treat a range of clinical conditions including depression.

Software models more detailed evolutionary networks from genetic data

Wed, 11/12/2014 - 18:21
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

Wed, 11/12/2014 - 17:01
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.

Predicting dengue fever outbreaks in China using Internet searches

Wed, 11/12/2014 - 14:31
The habit of searching online for a diagnosis before visiting the doctor can be a powerful predictor of infectious diseases outbreaks, researchers have found. Now studies show that combining information from monitoring internet search metrics such as Baidu (China's equivalent of Google), with a web-based infectious disease alert system from reported cases and environmental factors hold the key to improving early warning systems and reducing the deadly effects of dengue fever in China.

Virtual reality speeds up rehabilitation: Integrating force feedback into therapies for impaired hands

Wed, 11/12/2014 - 14:30
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.

'Nudges' try to help college students live healthier

Wed, 11/12/2014 - 14:30
Here's one way to try to get college students to live healthier lifestyles: They log onto their computer and get lessons and emails, telling them why they should eat better, exercise and sleep right. That's what researchers at 13 universities discovered.

From video camera to driverless shuttle vehicle

Wed, 11/12/2014 - 13:42
A new type of driverless shuttle vehicle has been developed thanks to innovative computer vision guidance technology that enables the vehicle to locate itself on a roadway reliably and inexpensively.

Music will never be the same

Wed, 11/12/2014 - 13:42
Computer scientists and musicologists have developed totally new software that allows you to put your own personal touch to your music.

Using 3-D printers to print out self-learning robots

Wed, 11/12/2014 - 13:41
On the third floor of the Department of Informatics in a university in Norway a there is a robotics laboratory which looks like a playroom. This is where researchers are testing how their robots can figure out how to move past barriers and other obstacles. The robotics team are currently comparing the performance of five robots which in theory should be equally good. Three of the five robots have four legs, one has three, another has six. The fewer legs, the less energy is consumed. One of the robots is fitted with single-joint legs. The others have legs with two joints.

Electric cars without drivers

Wed, 11/12/2014 - 13:41
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

Wed, 11/12/2014 - 13:38
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.
