Scientists at Ames Laboratory have demonstrated broadband terahertz (THz) wave generation using metamaterials. The discovery may help develop noninvasive imaging and sensing, and make possible THz-speed information communication, processing and storage.
Expectations are high for RoboEarth, a new European-funded system to speed the development of human-serving robots. Scientists from five major European technical universities have gathered in the Netherlands this week for its launch and to demonstrate possible applications. The first: the deceptively simple task of delivering a glass of milk to a patient in a mock-up hospital room.
Computer scientist Yi-Kai Liu at NIST has devised a way to make a security device that has proved notoriously difficult to build: a "one-shot" memory unit, whose contents can be read only a single time. The innovation, which uses qubits and conjugate coding, shows in theory how the laws of quantum physics could allow for the construction of such memory devices.
When our Internet-connected gadgets and home appliances all learn to talk to each other, Google wants to be at the center of the conversation. This imagined future is still a few years away, but the search giant is already preparing with its $3.2 billion acquisition of high-tech thermostat and smoke-detector maker Nest Labs.
New research finds that the social benefits of autonomous vehicles will outweigh the likely disadvantages. Decreased crashes, increased mobility, and increases in fuel economy will drive the technology forward, says RAND Corp. researchers, despite privacy concerns and need for updates in insurance regulations.
Researchers at the Massachusetts Institute of Technology have found a way to allow people in one place to interact with 3-D versions of people or objects in a different location. MIT's Tangible Media Group calls the technology inFORM, and it could one day be used by architects, urban planners, or even doctors who need to look at computed tomography scans.
The completion of the 30-day Lunar Laser Communication Demonstration (LLCD) mission has helped confirm laser communication capabilities from a distance of almost 250,000 miles. In addition to demonstrating record-breaking data download and upload speeds to the moon at 622 and 20 Mbps, respectively, LLCD also showed that it could operate as well as any NASA radio system.
After successfully text messaging “O Canada” using evaporated vodka, two researchers in Canada and their UK-based counterpart say their simple system can be used where conventional wireless technology fails. The chemical signal, using the alcohol found in vodka, was sent 4 m across the lab with the aid of a tabletop fan.
Researchers at The Univ. of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation. The team has proposed a design for an active cloak that draws energy from a battery, allowing objects to become undetectable to radio sensors over a greater range of frequencies.
Although high-definition displays on smartphones have gotten bigger and their cameras have gotten better, the pace of gee-whiz innovation has dawdled. Smartphone and software makers are working on ways to snap out of this technological lull, although it probably will be at least another year or two before breakthroughs revolutionize the design and function of mobile computing devices.
Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there’s been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components. With antennas made from conventional materials like copper, communication between low-power nanomachines would be virtually impossible.
The NSA chief said Wednesday he knows of no better way his agency can help protect the U.S. from foreign threats than with spy programs that collect phone and Internet records from around the world. Pleading with the Senate Judiciary Committee to not abolish the National Security Agency's bulk-collection programs, Gen. Keith Alexander warned that global threats are growing that pose what he called "an unacceptable risk" to America.
Gaming could become much more realistic with new technology developed at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) that permits highly accurate, 3-D motion tracking. The new system, dubbed “WiTrack”, uses radio signals to track a person through walls and obstructions, pinpointing her 3-D location to within 10 to 20 cm, about the width of an adult hand.
A connected vehicle network, with vehicles exchanging information with the highway infrastructure and other vehicles using wireless communications, could improve traffic safety, mobility and environmental impacts. Southwest Research Institute, which has considerable expertise in intelligent vehicle development, is now serving as an official Connected Vehicle Affiliated Test Bed for this technology.
The information and communications technologies (ICT) industry, and the significant level of R&D that supports it, is driven by constant change in consumer preferences, market demand and technological evolution. The ICT industry is the largest private-sector R&D investor in the U.S., performing nearly one-third of the total.
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived. A team of physicists believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
Researchers in Switzerland have managed to combine antennas and solar cells to work together with unprecedented efficiency in a near future. This is a first step towards more compact and more lightweight satellites. The technology could also be deployed in the autonomous antenna systems used in the aftermath of natural disasters.
The Office of Naval Research is demonstrating the Fleet Integrated Synthetic Training/Testing Facility (FIST2FAC) in Florida this week, showing how gaming technology is helping naval forces develop operations strategies in a hassle-free way.
Online retailer Amazon.com aiming to deliver packages quicker than pizza. Its so-called Prime Air unmanned aircraft project, now underway in Amazon’s research and development labs, could get goods to customers in 30 minutes or less. But the company admits it will take years to advance the needed technology and for the needed federal Aviation Administration rules and regulations to be created.
Lidar rangefinders gauge depth by emitting short bursts of laser light and measuring the time it takes for reflected photons to arrive back and be detected. In Science, researchers from Massachusetts Institute of Technology’s Research Laboratory of Electronics describe a new lidar-like system that can gauge depth when only a single photon is detected from each location.
Where do you go to look at the stars? Away from city lights, certainly. But if you're serious about peering far out into space, to the observable edges of our universe, at submillimeter wavelengths, you have to do a little better than that. You have to go farther and higher, up to where the atmosphere is thin. And if you want to look at the stars for more than a few nights a year, you also need some place that is very, very dry.
Suggesting that quantum computers might benefit from losing some data, physicists at NIST have entangled—linked the quantum properties of—two ions by leaking judiciously chosen information to the environment. The NIST experiments used two beryllium ions as quantum bits (qubits) to store quantum information and two partner magnesium ions, which were cooled with three ultraviolet laser beams to release heat.
Spontaneous bursts of light from a solid block illuminate the unusual way interacting quantum particles behave when they are driven far from equilibrium. The discovery by Rice Univ. scientists of a way to trigger these flashes may lead to new telecommunications equipment and other devices that transmit signals at picosecond speeds.
Buried under thousands of miles of pavement in California are 27,000 traffic sensors that are supposed to help troubleshoot both daily commutes and long-term maintenance needs on some of the nation's most heavily used and congested roadways. About 9,000 of them do not work, despite their critical role in an "intelligent transportation" system designed to do things like detect the congestion that quickly builds after an accident.
The scientist credited with inventing the World Wide Web, Tim Berners-Lee, says a growing tide of surveillance is threatening democracy's future. Lee, a former R&D Magazine Scientist of the Year said Friday that as more people use the Internet and social media to "expose wrongdoing," some governments are feeling threatened.
