From smartphones and tablets to computer monitors and interactive TV screens, electronic displays are everywhere. As the demand for instant, constant communication grows, so too does the urgency for more convenient portable devices, especially devices, like computer displays, that can be easily rolled up and put away, rather than requiring a flat surface for storage and transportation.

Studies confirm that IT investments in companies improve productivity and efficiency. Univ. of Michigan professor M.S. Krishnan wondered if the same was true for government. After all, IT spending could either lead to efficiency or create bureaucratic bloat.
Washington State Univ. mathematicians have designed an encryption code capable of fending off the phenomenal hacking power of a quantum computer. Using high-level number theory and cryptography, the researchers reworked an infamous old cipher called the knapsack code to create an online security system better prepared for future demands.
For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers’ conventional notion that proteins have a static and well-defined structure. It’s thought that mutations in these proteins, known as intrinsically disordered proteins, are associated with neurodegenerative changes, cardiovascular disorders and diseases like cancer.
Virtual reality games often cause simulator sickness, but new research findings point to a potential strategy to ease the affliction. Various physiological systems govern the onset of simulator sickness: a person's overall sense of touch and position, or the somatosensory system; liquid-filled tubes in the ear called the vestibular system; and the oculumotor system, or muscles that control eye movements.
The team demonstrated a quantum on/off switching time of about a millionth of a millionth of a second—the fastest-ever quantum switch to be achieved with silicon and over a thousand times faster than previous attempts. The team will investigate how to connect quantum objects to each other, creating the bigger building blocks needed for quantum computers.
Scientists at Los Alamos National Laboratory have developed a new method for DNA analysis of microbial communities such as those found in the ocean, the soil and our own guts. Metagenomics is the study of entire microbial communities using genomics.
Our fast-approaching future of driverless cars and “smart” electrical grids will depend on billions of linked devices making decisions and communicating with split-second precision to prevent highway collisions and power outages. But a new report released by NIST warns that this future could be stalled by our lack of effective methods to marry computers and networks with timing systems.
Using the quantum property of superposition, quantum computers will be able to find target items within large piles of data far faster than conventional computers ever could. But the speed of the search will likely depend on the structure of the data. Such a search would proceed as a quantum particle jumps from one node of a connected set of data to another. Intuition says that the search would be fastest in a highly connected database.
One of life's strongest bonds has been discovered by a science team researching biofuels with the help of supercomputers. Their find could boost efforts to develop catalysts for biofuel production from non-food waste plants.
Researchers from the Univ. of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.
Mother-of-pearl, the iridescent layer in the shells of some mollusks, inspired a Rice Univ. study that will help scientists and engineers judge the ultimate strength, stiffness and toughness of composite materials for anything from nanoscale electronics to buildings.
Computers that function like the human brain could soon become a reality thanks to new research using optical fibers made of specialty glass. The research, published in Advanced Optical Materials, has the potential to allow faster and smarter optical computers capable of learning and evolving.
Researchers from Brown and Johns Hopkins have come up with a new way to evaluate how well computers can divine information from images. The team describes its new system as a “visual Turing test,” after the legendary computer scientist Alan Turing’s test of the extent to which computers display human-like intelligence.
The editors of R&D Magazine have announced an eligibility extension for products to be entered into the 2015 R&D 100 Awards. The 2015 R&D 100 Awards will honor products, technologies and services that have been introduced to the market between January 1, 2014 and March 31, 2015.
Targeting stagnant wages in an otherwise improving economy, President Barack Obama is calling on employers, educational institutions and local governments to ramp up training and hiring of high-technology in an effort to drive up higher-income employment.
When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers by comparison. But, before that happens, quantum physicists will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit.
With the most unpredictable U.K. general election looming in modern times, how can big data be used to understand how elections are covered by the media? New research has, for the first time, analyzed over 130,000 online news articles to find out how the 2012 U.S. presidential election played out in the media.
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.
Computational Model Reveals the Importance of Transitional Dynamics of “Memory Molecule” in Memory FormationFebruary 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.
Ninety percent of automobile accidents involve human error. If scientists succeed in producing computer-driven cars, responsibility may shift to programming errors. In that case, who sues whom? Who is liable?
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.
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.
When electronic states in materials are excited during dynamic processes, interesting phenomena such as electrical charge transfer can take place on quadrillionth-of-a-second, or femtosecond, timescales. Numerical simulations in real time provide the best way to study these processes, but such simulations can be extremely expensive.
Scientists used supercomputers to find a new class of materials that possess an exotic state of matter known as the quantum spin Hall effect. The researchers published their results in Science in December 2014, where they propose a new type of transistor made from these materials. The team calculated the electronic structures of the materials using the Stampede and Lonestar supercomputers of the Texas Advanced Computing Center.
Phishing emails are more and more common as entry points for hackers— unwittingly clicking on a link in a scam email could unleash malware into a network or provide other access to cyberthieves. A growing number of companies, including Twitter Inc., are giving their workers' a pop quiz, testing security savvy by sending spoof phishing emails to see who bites.
