Collecting digital user data without invading privacy

March 7, 2014 9:47 am | by EurekAlert! | News | Comments

The statistical evaluation of digital user data is of vital importance for analyzing trends. But it can also undermine the privacy. Computer scientists from Saarbrücken have now developed a novel cryptographic method that makes it possible to collect data and protect the privacy of the user at the same time. They present their approach for the first time at the computer expo CeBIT in Hannover at the Saarland University research booth.

IUPUI researchers use computers to "see" neurons to better understand brain function

March 7, 2014 9:32 am | by EurekAlert! | News | Comments

A study conducted by local high school students and faculty from the Department of Computer and Information Science in the School of Science at Indiana University-Purdue University Indianapolis reveals new information about the motor circuits of the brain that may one day help those developing therapies to treat conditions such as stroke, schizophrenia, spinal cord injury or Alzheimer's disease.

Squeezing light into metals

March 7, 2014 9:26 am | by EurekAlert! | News | Comments

Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Colored diamonds are a superconductor’s best friend

March 7, 2014 9:15 am | by EurekAlert! | News | Comments

Flawed but colorful diamonds are among the most sensitive detectors of magnetic fields known today, allowing physicists to explore the minuscule magnetic fields in metals, exotic materials and even human tissue. Dmitry Budker and colleagues have now shown that these diamond sensors can measure the tiny magnetic fields in high-temperature superconductors, providing a new tool to probe these much ballyhooed but poorly understood materials.

Up-converted radio

March 7, 2014 9:05 am | by EurekAlert! | News | Comments

Ever worry about losing your mobile-phone reception? The same problem hampers cosmologists looking at the early universe, a glimpse embodied in the cosmic microwave background. All three of these efforts depend on discriminating weak radio signals from a noisy environment. A new approach to this problem provides a clean, all-optical detection of  radiowaves featuring noise mitigation a thousand times better than existing methods.

Photos of the Day: The AT Black Knight Transformer

March 7, 2014 8:55 am | News | Comments

The AT Black Knight Transformer is the world’s first roadable, vertical takeoff and landing (VTOL) aircraft. It has the ability to transform from a VTOL helicopter to an off-road vehicle. The Black Knight was designed as a rapid-response evac vehicle for wounded soldiers or cargo transport.

Preschoolers outsmart college students at figuring out gizmos

March 7, 2014 8:54 am | by EurekAlert! | News | Comments

Preschoolers can be smarter than college students at figuring out how unusual gadgets work because they’re more flexible and less biased than adults in their ideas about cause and effect. The findings suggest that technology and innovation can benefit from the exploratory learning and probabilistic reasoning skills that come naturally to young children, many of whom are learning to use smartphones even before they can tie their shoelaces..
