Breakthrough in OLED technology

March 2, 2015 12:27 pm | by Jason Socrates Bardi, American Institute of Physics | News | Comments

Organic light-emitting diodes (OLEDs), which are made from carbon-containing materials, have the potential to revolutionize future display technologies, making low-power displays so thin they'll wrap or fold around other structures, for instance. Conventional LCD displays must be backlit by either fluorescent light bulbs or conventional LEDs whereas OLEDs don't require back lighting.

February 27, 2015 9:53 am | by Vincent Horiuchi, Univ. of Utah | News | Comments

Univ. of Utah engineers have discovered a new approach for designing filters capable of separating different frequencies in the terahertz spectrum, the next generation of communications bandwidth that could allow cellphone users and Internet surfers to download data a thousand times faster than today. Once the filter is designed, it can be fabricated using an off-the-shelf inkjet printer.

Research signals big future for quantum radar

February 27, 2015 7:55 am | by David Garner, Univ. of York | News | Comments

A prototype quantum radar that has the potential to detect objects which are invisible to conventional systems has been developed by an international research team led by a quantum information scientist at the Univ. of York. The new breed of radar is a hybrid system that uses quantum correlation between microwave and optical beams to detect objects of low reflectivity, such as cancer cells or aircraft with a stealth capability.

Physicists at Yale Univ. have observed a new form of quantum friction that could serve as a basis for robust information storage in quantum computers in the future. The researchers are building upon decades of research, experimentally demonstrating a procedure theorized nearly 30 years ago.

Using “fuzzy logic” to optimize hybrid solar/battery systems

February 26, 2015 11:11 am | by American Institute of Physics | News | Comments

How did fuzzy logic help a group of researchers in Tunisia and Algeria create an ideal photovoltaic system that obeys the supply-and-demand principle and its delicate balance? In the Journal of Renewable & Sustainable Energy, the group describes a new sizing system of a solar array and a battery in a standalone photovoltaic system that is based on fuzzy logic.

Smartphones could tell consumers what's in food

February 26, 2015 9:09 am | by Mary Clare Jalonick, Associated Press | News | Comments

In the ever-complicated debate over labeling of genetically modified foods, Agriculture Secretary Tom Vilsack says he has an idea: use your smartphone. Vilsack told members of Congress on Wednesday that consumers could just use their phones to scan special bar codes or other symbols on food packages in the grocery store. All sorts of information could pop up, such as whether the food's ingredients include genetically modified organisms.

Optical nanoantennas set the stage for a NEMS lab-on-a-chip revolution

February 24, 2015 11:19 am | by Jason Socrates Bardi, American Institute of Physics | News | Comments

Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer. The new antennas are cubic in shape. They do a better job than previous spherical ones at directing an ultra-narrow beam of light where it is needed, with little or no loss due to heating and scattering.

Computational Model Reveals the Importance of Transitional Dynamics of “Memory Molecule” in Memory Formation

February 24, 2015 9:01 am | by Glen C. Rains | Articles | Comments

The dynamics of a molecule abundant in the synapse, Ca2+/Calmodulin dependent kinase type II (CaMKII), known as the “memory molecule”, are important in memory formation. Synapses are junctions connecting neurons and there’s increasing evidence they store memory when neurons are stimulated by the environment.

Radio chip for the Internet of things

February 23, 2015 7:46 am | by Larry Hardesty, MIT News Office | News | Comments

At this year’s Consumer Electronics Show, the big theme was the “Internet of things”: the idea that everything in the human environment could be equipped with sensors and processors that can exchange data, helping with maintenance and the coordination of tasks. Realizing that vision, however, requires transmitters that are powerful enough to broadcast to devices dozens of yards away but energy-efficient enough to last for months.

Turning smartphones into personal, real-time pollution monitors

February 20, 2015 8:48 am | by American Chemical Society | News | Comments

As urban residents know, air quality is a big deal. When local pollution levels go up, the associated health risks also increase, especially for children and seniors. But air pollution varies widely over the course of a day and by location, even within the same city. Now scientists, reporting in Environmental Science & Technology, have used smartphone and sensing technology to better pinpoint where and when pollution is at its worst.

HTTP Gets an Update

February 19, 2015 2:00 pm | by The Conversation, Peter Maynard | News | Comments

Hypertext Transfer Protocol, HTTP, is a key component of the World Wide Web. It is the communications layer through which web browsers request web pages from web servers and with which web servers respond with the contents of the page. Like much of the internet it’s been around for decades, but a recent announcement reveals that HTTP/2, the first major update in 15 years, is about to arrive.  

Smarter multicore chips

February 18, 2015 7:33 am | by Larry Hardesty, MIT News Office | News | Comments

Computer chips’ clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel. But the ways in which a chip carves up computations can make a big difference to performance.
