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.
Univ. of Notre Dame applied mathematician Mark Alber and environmental biotechnologist Robert Nerenberg have developed a new computational model that effectively simulates the mechanical behavior of biofilms. Their model may lead to new strategies for studying a range of issues from blood clots to waste treatment systems.
Using high-performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion people on it by 2050, researchers report in Cell.
Scientists working at NIST and the NIH have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering.
Big data: It's a term we read and hear about often, but is hard to grasp. Computer scientists at Washington Univ. in St. Louis tackled some big data about an important protein and discovered its connection in human history as well as clues about its role in complex neurological diseases.
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.
We live in an increasingly wireless world where self-powered devices are becoming integral to everyday life. A plethora of next-generation wireless technologies are seeing dramatic growth, involving both consumer and industrial applications. Some of the industrial applications include utility meter reading (AMR/AMI), wireless mesh networks, M2M and system control and data acquisition (SCADA) and data loggers, to name a few.
Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water. There are other semiconductors. Gallium arsenide is one such material and it has certain technical advantages over silicon.
Los Alamos National Laboratory mechanical and thermal engineering researchers’ efforts to solve the complex problem of how ocean currents affect the infrastructure of floating oilrigs and their computational fluid dynamics numerical simulations received recognition from ANSYS Inc.
Rechargeable lithium-ion batteries are commonly found in portable electronics such as cell phones and notebook PCs. They’re also gaining popularity in electric vehicles, where their compact, lightweight build and high-energy storage potential offers a more efficient and environmentally safe alternative to nickel metal hydride and lead-acid batteries traditionally used in vehicles.
Researchers at Carnegie Mellon Univ. (CMU) who develop snake-like robots have picked up a few tricks from real sidewinder rattlesnakes on how to make rapid and even sharp turns with their undulating, modular device. Working with colleagues at the Georgia Institute of Technology and Zoo Atlanta, they have analyzed the motions of sidewinders and tested their observations on CMU’s snake robots.
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 most realistic risks about the dangers of artificial intelligence are basic mistakes, breakdowns and cyber attacks, an expert in the field says—more so than machines that become super powerful, run amok and try to destroy the human race.
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.
Projects that target aid toward villages and rural areas in the developing world often face time-consuming challenges, even at the most basic level of figuring out where the most appropriate sites are for pilot programs or deployment of new systems such as solar-power for regions that have no access to electricity. Often, even the sizes and locations of villages are poorly mapped, so time-consuming field studies are needed.
Squid are the ultimate camouflage artists, blending almost flawlessly with their backgrounds so that unsuspecting prey can't detect them. Using a protein that's key to this process, scientists have designed "invisibility stickers" that could one day help soldiers disguise themselves, even when sought by enemies with tough-to-fool infrared cameras.
Imagine a bridge or a dam that could sense a structural defect before it happens, diagnose what the problem will be and alert the authorities before something bad happens. Three Michigan State Univ. researchers are developing a new technology known as substrate computing. This will allow sensing, communication and diagnostic computing, all within the substrate of a structure, using energy harvested from the structure itself.
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.
A device resembling a plastic honeycomb, yet infinitely smaller than a bee’s stinger, can steer light beams around tighter curves than ever before possible, while keeping the integrity and intensity of the beam intact. The work introduces a more effective way to transmit data rapidly on electronic circuit boards by using light.
Univ. of Nebraska-Lincoln engineers have become the first to develop a model that literally looks beyond the surface of corrosion to better predict its spread. The model's unique capabilities could allow engineers to more precisely forecast catastrophic structural failures and design materials less susceptible to the widespread issue, the researchers reported.
A paper published in Scientific Reports by a team led by physicist Igor Aronson of the Argonne National Laboratory modeled the motion of cells moving together. This may help scientists design new technologies inspired by nature, such as self-healing materials in batteries and other devices. Scientists have been borrowing ideas from the natural world for hundreds of years.
From computers, tablets and smartphones to cars, homes and public transportation, our world is more digitally connected every day. The technology required to support the exchange of massive quantities of data is critical. That's why scientists and engineers are intent on developing faster computing units capable of supporting much larger amounts of data transfer and data processing.
