Platinum meets its match in quantum dots from coal

October 1, 2014 5:20 pm | by EurekAlert! | Comments

Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions....

Louisiana Tech University, CSC develop curriculum to support high-tech workforce needs

October 1, 2014 5:17 pm | by EurekAlert! | Comments

Faculty from Louisiana Tech University's cyber engineering, computer science, and computer information systems programs, and research and development group hosted over 30 executives from CSC, a global leader in next-generation IT, last week....

Stressed out: Research sheds new light on why rechargeable batteries fail

October 1, 2014 5:12 pm | by EurekAlert! | Comments

Pity the poor lithium ion. Drawn relentlessly by its electrical charge, it surges from anode to cathode and back again, shouldering its way through an elaborate molecular obstacle course. This journey is essential to powering everything from cell phones....

New absorber will lead to better biosensors

October 1, 2014 5:09 pm | by EurekAlert! | Comments

Biological sensors, or biosensors, are like technological canaries in the coalmine. By converting a biological response into an optical or electrical signal, they can alert us to dangers in our external and internal environments. They can sense toxic chemicals....

New frontier in error-correcting codes

October 1, 2014 5:04 pm | by EurekAlert! | Comments

Error-correcting codes are one of the glories of the information age: They're what guarantee the flawless transmission of digital information over the airwaves or through copper wire, even in the presence of the corrupting influences that engineers call "noise"....

Solving the mystery of the 'man in the moon'

October 1, 2014 5:01 pm | by EurekAlert! | Comments

New data obtained by NASA's GRAIL mission reveals that the Procellarum region on the near side of the moon — a giant basin often referred to as the "man in the moon" — likely arose not from a massive asteroid strike, but from a large plume....

App teaches kindergartners basic computer coding

October 1, 2014 4:41 pm | by RODRIQUE NGOWI, Associated Press | Comments

This computer programming app is so easy to use that even a kindergartener can do it. Researchers in Massachusetts have created a basic computer coding app that they say is the first designed specifically for children as young as 5....

Novel porous silicon microfabrication technique increases sensing ability

October 1, 2014 4:35 pm | by Georgia Institute of Technology | Comments

Georgia Institute of Technology researchers have developed a novel method for improving silicon-based sensors used to detect biochemicals and other molecules in liquids. The simplified approach produces micro-scale optical detection devices....

Windows 10 tries blending new with familiar

September 30, 2014 7:29 pm | by Brandon Bailey - AP Technology Writer - Associated Press | Comments

Microsoft is trying to soften an unpopular redesign of Windows by reviving features from older versions while still attempting to nudge desktop users into a world of touch screens and mobile devices. The company on Tuesday gave an early preview of the new Windows 10 software, which it aims to...

Ultrafast remote switching of light emission

September 30, 2014 4:29 pm | by EurekAlert! | Comments

The researchers etched a photonic crystal around several quantum dots in a semiconductor layer. Quantum dots are small structures that spontaneously emit light as a consequence of atomic processes. If a short laser pulse is fired at the photonic....

Modeling shockwaves through the brain

September 30, 2014 3:40 pm | by EurekAlert! | Comments

Since the start of the military conflicts in Iraq and Afghanistan, more than 300,000 soldiers have returned to the United States with traumatic brain injury caused by exposure to bomb blasts — and in particular, exposure to improvised explosive....

Nitrogen fingerprint in biomolecules could be from early sun

September 30, 2014 3:28 pm | by EurekAlert! | Comments

Chemical fingerprints of the element nitrogen vary by extremes in materials from the molecules of life to the solar wind to interstellar dust. Ideas for how this great variety came about have included alien molecules shuttled in by icy comets....
