Controlling magnetic clouds in graphene

Wed, 06/12/2013 - 13:35
Wonder material graphene can be made magnetic and its magnetism switched on and off at the press of a button, opening a new avenue towards electronics with very low energy consumption. Scientists have now shown how to create elementary magnetic moments in graphene and then switch them on and off.

Video gamers really do see more: Gamers capture more information faster for visual decision-making

Tue, 06/11/2013 - 20:19
Hours spent at the video gaming console not only train a player's hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to researchers.

Cloud computing user privacy in serious need of reform, scholars say

Tue, 06/11/2013 - 19:44
The current "non-negotiable approach" to user privacy is in need of serious revision, especially with the increased popularity of web-based software that shares information via cloud computing, experts say.

New tasks become as simple as waving a hand with brain-computer interfaces

Tue, 06/11/2013 - 18:33
Researchers have demonstrated that when humans use brain-computer interfaces, the brain behaves much like it does when completing simple motor skills such as kicking a ball, typing or waving a hand. Learning to control a robotic arm or a prosthetic limb could become second nature for people who are paralyzed.

Potential disease-transmission sources in animals ID'd by calculating risk using social network mathematics

Tue, 06/11/2013 - 14:20
Scientists have successfully identified animal species that can transmit more diseases to humans by using mathematical tools similar to those applied to the study of social networks like Facebook or Twitter. Their research describes how parasite-primate interactions transmit diseases like malaria, yellow fever or AIDS to humans. Their findings could make an important contribution to predicting the animal species most likely to cause future pandemics.

Electric cars in action: Small and medium-sized companies sharing fleets of electric vehicles

Tue, 06/11/2013 - 14:20
Imagine a number of different companies sharing a single fleet of electric vehicles. Researchers in Germany are busy working out just how to make this vision a reality. The Shared E-Fleet research project aims not only to work up suitable IT solutions, but also to design the smart energy management and profitable business models that are called for.

Effective privacy protection in social networks

Tue, 06/11/2013 - 12:42
Researchers are working on new methods to help them gain a better understanding of the usage habits of participants in social networks. The results will be incorporated in the development of userfriendly tools for privacy protection.

Intelligent door seal prevents poor air quality

Tue, 06/11/2013 - 12:41
For a long time, heat insulation was en vogue -- and nearly no one was concerned about poor indoor air quality. And yet excess carbon dioxide hampers concentration. Now, researchers have come up with an intelligent door seal system.

Pendulum swings back on 350-year-old mathematical mystery

Mon, 06/10/2013 - 17:31
A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, researchers report.

2-D electronics take a step forward: Semiconducting films for atom-thick circuits

Mon, 06/10/2013 - 17:31
Scientists have created single-layer films of molybdenum disulfide, a semiconductor and an important component in the development of two-dimensional electronics.

When will my computer understand me?

Mon, 06/10/2013 - 15:30
For more than 50 years, linguists and computer scientists have tried to get computers to understand human language by programming semantics as software, with mixed results. Enabled by supercomputers, researchers are using new methods to more accurately represent language so computers can interpret it.

Teacher collaboration, professional communities improve many elementary school students' math scores

Fri, 06/07/2013 - 20:03
Many elementary students' math performance improves when their teachers collaborate, work in professional learning communities or do both, yet most students don't spend all of their elementary school years in these settings, a new study shows. The researchers used a sub-sample of 4,490 students, who attended public elementary schools between 1998 and 2003, from the US Department of Education's nationally representative Early Childhood Longitudinal Study.

Making sense of patterns in the Twitterverse

Fri, 06/07/2013 - 17:10
If you think keeping up with what's happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by seven billion -- and you'll have a sense of what Court Corley wakes up to every morning. Corley has created a powerful digital system, dubbed SALSA, capable of analyzing billions of tweets and other messages in just seconds, in an effort to discover patterns and make sense of all the information.

How do immune cells detect infections?

Fri, 06/07/2013 - 17:05
Researchers are using computer simulations to shed light on how immune cells may identify foreign antigens.

Better screens made of organic light diodes: OLED brings out the shine

Fri, 06/07/2013 - 12:52
Screens made of organic light diodes promise unfathomable possibilities. Yet high production costs often prevent their widespread use. A new kind of production saves not only costs, but also improves the radiance of the OLED.
