Video gamers really do see more: Gamers capture more information faster for visual decision-making Posted: 11 Jun 2013 01:19 PM PDT 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.

Exposure to air transforms gold alloys into catalytic nanostructures Posted: 11 Jun 2013 01:19 PM PDT Scientists have created promising gold-indium oxide nanoparticles through room-temperature oxidation.

Cloud computing user privacy in serious need of reform, scholars say Posted: 11 Jun 2013 12:44 PM PDT 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.

Marks on Martian dunes may be tracks of dry-ice sleds Posted: 11 Jun 2013 11:51 AM PDT NASA research indicates hunks of frozen carbon dioxide -- dry ice -- may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go. Researchers deduced this process could explain one enigmatic class of gullies seen on Martian sand dunes by examining images from NASA's Mars Reconnaissance Orbiter (MRO) and performing experiments on sand dunes in Utah and California.

Shining a light on cool pools of gas in the galaxy Posted: 11 Jun 2013 11:48 AM PDT Newly formed stars shine brightly, practically crying out, "Hey, look at me!" But not everything in our Milky Way galaxy is easy to see. The bulk of material between the stars in the galaxy -- the cool hydrogen gas from which stars spring -- is nearly impossible to find.

Black hole naps amidst stellar chaos Posted: 11 Jun 2013 11:45 AM PDT Nearly a decade ago, NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which sees higher-energy X-ray light, has taken a peek and found the black hole asleep.

Moon radiation findings may reduce health risks to astronauts Posted: 11 Jun 2013 11:43 AM PDT Space scientists report that data gathered by NASA's Lunar Reconnaissance Orbiter show lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel. The finding could help reduce health risks to humans on future missions into deep space.

New tasks become as simple as waving a hand with brain-computer interfaces Posted: 11 Jun 2013 11:33 AM PDT 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.

Polymer nanoreactors create uniform nanocrystals Posted: 11 Jun 2013 10:09 AM PDT Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures – including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals.

Graphene and semiconductor technology together: Smaller, cheaper, better Posted: 11 Jun 2013 05:42 AM PDT Mobile phones that bend, self-powered nanodevices, new and improved solar cell technology and windows that generate electricity are but a few of the potential products from the union of semiconductors and graphene.

Effective privacy protection in social networks Posted: 11 Jun 2013 05:42 AM PDT 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.

Less friction loss in combustion engines Posted: 11 Jun 2013 05:42 AM PDT Researchers have developed a method that can reduce engine friction and wear even during production of engine components. Special coatings can help to reduce fuel consumption and carbon dioxide emissions.

Intelligent door seal prevents poor air quality Posted: 11 Jun 2013 05:41 AM PDT 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.

'Popcorn' particle pathways promise better lithium-ion batteries Posted: 11 Jun 2013 05:22 AM PDT Researchers have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate, findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft.
