In what is believed to be U.S. first, physician uses telehealth to replace comprehensive face-to-face visit for home dialysis patient

Tue, 06/21/2016 - 18:40
A telehealth program is being piloted, which could open the door for patients in rural communities to receive more subspecialized care without traveling long distances.

Compiler for analog computers enhances biological modeling

Tue, 06/21/2016 - 15:56
A new compiler for analog computers has been developed, a program that translates between high-level instructions written in a language intelligible to humans and the low-level specifications of circuit connections in an analog computer. The work could help pave the way to highly efficient, highly accurate analog simulations of entire organs.

Drones could be cheaper alternative to delivering vaccines in developing world

Tue, 06/21/2016 - 15:21
Using unmanned drones to deliver vaccines in low- and middle-income countries may save money and improve vaccination rates, new research suggests.

Gamble on your opponent's gaze if you want to win

Tue, 06/21/2016 - 15:15
Blackjack players who hold high-value cards tend to glance fleetingly to the right, whereas those with a lower-value hand do so spontaneously to the left. This is according to research on aspects of mental arithmetic.

Understanding rogue ocean waves may be simple after all

Tue, 06/21/2016 - 13:10
An international team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high.

Ten simple rules to use statistics effectively

Mon, 06/20/2016 - 23:14
Under growing pressure to report accurate findings as they interpret increasingly larger amounts of data, researchers are finding it more important than ever to follow sound statistical practices.

Power of supercomputing to find rare-earth refining alternatives

Mon, 06/20/2016 - 20:17
Scientists have identified agents for the separation of rare-earth metals that are potentially much less costly and better-performing than those currently used.

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.
