RedEye could let your phone see 24-7

Mon, 06/20/2016 - 20:11
Researchers have just the thing for information overload: image-processing technology that sees all and remembers only what it should. RedEye could allow computers to continuously see what their owners see.

Better way to 'herd' electrons in solar fuel devices

Mon, 06/20/2016 - 18:13
Researchers have discovered a new way to optimize electron transfer in semi-conductors used in solar fuel solutions.

Quantum calculations broaden the understanding of crystal catalysts

Mon, 06/20/2016 - 18:13
Recently, scientists advanced in explaining the properties of rutile TiO2 -- a promising photocatalyst, which may be used to produce eco-friendly fuel and to neutralize harmful compounds Using a supercomputer, researchers managed to model the behavior of surface layers of the crystal. This has led to a number of interesting discoveries, thus significantly broadening the current understanding of photocatalysis and bringing closer its practical applications.

Crowdsourcing platform makes public gene expression data more accessible

Mon, 06/20/2016 - 16:03
Scientists have developed a free online platform that uses a crowdsourcing approach to make public gene expression data more accessible to biomedical researchers without computational expertise.

Chip makes parallel programs run faster with less code

Mon, 06/20/2016 - 16:03
Researchers present a new chip design they call Swarm, which should make parallel programs not only much more efficient but easier to write, too.

10,000 windows onto biomolecular information processing

Mon, 06/20/2016 - 15:59
A new 'brute force' technique has been developed to test thousands of biochemical reactions at once and quickly home in on the range of conditions where they work best. Until now, optimizing such biomolecular systems, which can be applied for example to diagnostics, would have required months or years of trial and error experiments, but with this new technique that could be shortened to days.

Titan shines light on high-temperature superconductor pathway

Mon, 06/20/2016 - 15:28
Scientists have used the Titan supercomputer at ORNL to simulate cuprates on the path to superconductivity. The team focused on a pivotal juncture on the cuprates’ path called the pseudogap phase, an in-between phase before superconductivity in which cuprates exhibit both insulating and conducting properties.

Ultra-thin solar cells can easily bend around a pencil

Mon, 06/20/2016 - 15:25
New flexible photovoltaics could power wearable electronics.

New technique improves accuracy of computer vision technologies

Mon, 06/20/2016 - 15:22
Researchers have developed a new technique that improves the ability of computer vision technologies to better identify and separate objects in an image, a process called segmentation.

Fixing vulnerabilities in Internet encryption protocol Transport Layer Security

Mon, 06/20/2016 - 14:04
The Internet encryption protocol TLS – short for Transport Layer Security – is being fundamentally modified. Involved in attacks, researchers have contributed to revealing security gaps in the protocol.

Artificial synapse rivals biological ones in energy consumption

Mon, 06/20/2016 - 14:03
Researchers have succeeded in fabricating an organic nanofiber electronic device that emulates not only the important working principles and energy consumption of biological synapses but also the morphology.

Robotic motion planning in real-time

Mon, 06/20/2016 - 14:01
Robots with multi-jointed arms must plan their motion, a difficult problem that requires time-consuming computation. Simply picking an object up in an environment that has not been pre-engineered for the robot may require several seconds of computation. A new computer processor for robotic motion-planning can plan up to 10,000 times faster than existing approaches while consuming a small fraction of the power.

Artificial intelligence achieves near-human performance in diagnosing breast cancer

Mon, 06/20/2016 - 12:52
Pathologists have been largely diagnosing disease the same way for the past 100 years, by manually reviewing images under a microscope. But new work suggests that computers can help doctors improve accuracy and significantly change the way cancer and other diseases are diagnosed.

Predicting loaf volume without baking the bread

Sat, 06/18/2016 - 01:59
When it comes to baking bread, the bigger the loaf, the better. But to determine the baking performance of wheat flour, food scientists had to bake a loaf of bread. That may not be necessary, thanks to a new mathematical model that uses specific dough parameters to predict loaf volume. That saves time and money.

World's first 1,000-processor chip

Sat, 06/18/2016 - 01:58
A microchip containing 1,000 independent programmable processors has been designed. The energy-efficient 'KiloCore' chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors.

Researchers open hairy new chapter in 3-D printing

Fri, 06/17/2016 - 18:06
Researchers have found a way to bypass a major design step in 3-D printing, to quickly and efficiently model and print thousands of hair-like structures. Instead of using conventional computer-aided design (CAD) software to draw thousands of individual hairs on a computer the team built a new software platform, called 'Cilllia,' that lets users define the angle, thickness, density, and height of thousands of hairs, in just a few minutes.
