A professor from Tel Aviv University is reconfiguring existing complementary metal-oxide-semiconductor (CMOS) chips designed for computers and turning them into high-frequency circuits. The ultimate goal of this project is to produce chips with radiation capabilities that are able to see through packaging and clothing to produce an image of what may be hidden beneath.
Physicists at the University of Vienna and the Austrian Academy of Sciences have achieved quantum teleportation over a record distance of 143 km. The experiment is a major step towards satellite-based quantum communication.
Researchers from the NIST Center for Nanoscale Science and Technology have demonstrated a low-noise device for changing the wavelength of light using nanofabricated waveguides created on a silicon-based platform using standard planar fabrication technology.
A "magic carpet" which can immediately detect when someone has fallen and can help to predict mobility problems has been demonstrated by University of Manchester scientists. Plastic optical fibers, laid on the underlay of a carpet, can bend when anyone treads on it and map, in real time, their walking patterns.
Because of the proliferation of mobile wireless devices, there is not enough radio spectrum to account for everybody's needs. To counter the problem, industry is trying to build systems that operate with more sharply defined channels so that more of them can fit within the available bandwidth. At Purdue University, the recent invention of nanoelectromechanical resonators may provide the solution.
Researchers from the Australian National University have taken a quantum leap towards developing the next generation of super-fast networks needed to drive future computers. The team has developed a technique that allows for quantum information to travel at higher bandwidth using a beam of light and the phenomenon called entanglement.
Engineering researchers at the University of Arkansas have received funding from the National Science Foundation to create distortion-tolerant communications for wireless networks that use very little power. The research will improve wireless sensors deployed in remote areas where these systems must rely on batteries or energy-harvesting devices for power.
Spintronic devices use electron spin, a subtle quantum characteristic, to write and read information. But to mobilize this emerging technology, scientists must understand exactly how to manipulate spin as a reliable carrier of computer code. Now, scientists at Brookhaven National Laboratory have precisely measured a key parameter of electron interactions called non-adiabatic spin torque that is essential to the future development of spintronic devices.
A collaboration between a Stanford University ant biologist and a computer scientist has revealed that the behavior of harvester ant as they forage for food mirrors the protocols that control traffic on the Internet.
Researchers from Rice University unveiled a new multi-antenna technology that could help wireless providers keep pace with the voracious demands of data-hungry smartphones and tablets. The technology aims to dramatically increase network capacity by allowing cell towers to simultaneously beam signals to more than a dozen customers on the same frequency.
Only a few decals and antennas set Stanford University’s white Audi TTS apart from any other Audi coupe. But Shelly, as the car is known, doesn’t have a driver when it’s circling Thunderhill Raceway in California at 120 mph. Controlled by sophisticated software, it posts lap times that rival those of professional drivers.
New technology under development by Syracuse University, Virginia Tech, and the Rochester Institute of Technology is designed to help public emergency response communication devices remain in contact with each other even if cell towers and Internet networks go down during a natural or manmade disaster. The system, Intelligent Deployable Augmented Wireless Gateway (iDAWG), will soon be tested in the field.
Scientists at the University of Glasgow have captured images of quantum entanglement on camera for the first time. Making use of a 201 by 201 pixel array, the highly sensitive camera observed the full field of the quantum light at the same time, allowing the team to see up to 2,500 different entangled dimensions or states.
New findings from a team of Lawrence Berkeley National Laboratory and Japanese scientists suggest that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well. A study at the Advanced Light Source revealed that contrary to suppositions, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon.
Electron microscopy reveals cellular structures in high detail, but only tiny portions of a cell can be seen at a time. A team of scientists has tackled this problem by developing new tools for stitching together thousands of electron microscopy images into single, high-resolution images of biological tissues—a "Google Earth" for cell biologists. A newly enhanced viewer is available for public use.
Quantum key distribution is not a new phenomenon and has been in commercial use for several years to secure communication networks. Recently, however, single particles of light, also known as photons, have been produced and implemented into a wireless QKD link, transmitting 40 cm through the air.
When it comes to delivering data to users, the Web still works brilliantly. But for other functions such as allowing users to move between wireless networks or companies to shift traffic among servers, engineers are forced to implement increasingly cumbersome tweaks. A team of Princeton University researchers has released a plan to cut through that tangle and provide a simple solution to many of the problems involved with the Internet's growing pains.
On August 1, 2007, without warning, the roadway suddenly disappeared beneath drivers on Minneapolis' I-35W Bridge, killing 13. In the five years since, advances in wireless sensor technology are making warning systems to prevent such tragedies affordable and practical. Both startups and federally initiatives are close to releasing systems that will be suitable for commercial use.
For the first time, researchers in France have succeeded in producing a nanoantenna from short strands of DNA, two gold nanoparticles, and a small fluorescent molecule that captures and emits light. This work could in the longer term lead to the development of more efficient light-emitting diodes, more compact solar cells or even be used in quantum cryptography.
A Tennessee company has licensed award-winning software from Oak Ridge National Laboratory (ORNL) that will help industries install wireless networks more cost-effectively in challenging environments such as mines, offshore drilling platforms and factory floors. Networcsim signed an agreement today to license the Radio Channel Simulator software, which won an R&D 100 Award this month.
Researchers have developed a new computational method that will make it easier for scientists to identify and prioritize genes, drug targets, and strategies for repositioning drugs that are already on the market. By mining large datasets more simply and efficiently, researchers will be able to better understand genomic and proteomics interactions, as well as identify fellow researchers with whom they can collaborate.
Researchers have found a way to use GPS to measure short-term changes in the rate of ice loss on Greenland—and reveal a surprising link between the ice and the atmosphere above it. The study hints at the potential for GPS to detect many consequences of climate change, including ice loss, the uplift of bedrock, changes in air pressure—and perhaps even sea level rise.
Carnegie Mellon University's new Pedo-Biometrics Lab is working to perfect special shoe insoles that can help monitor access to high-security areas, like nuclear power plants or special military bases. The concept is based on research that shows each person has unique feet, and ways of walking. Sensors check on the pressure of feet and the gait, using a computer to compare patterns.
Though smartphones and tablets are hailed as the hardware of the future, their present-day incarnations have some flaws. Most notoriously, low RAM memory limits the number of applications that can be run at one time and quickly consumes battery power. Now, a Tel Aviv University researcher has found a creative solution to these well-known problems.
