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.
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.
A new technique that allows curved surfaces to appear flat to electromagnetic waves has been developed by scientists in England. The discovery could hail a step-change in how antennas are tailored to each platform, which could be useful to a number of industries that rely on high performance antennas for reliable and efficient wireless communications.
A team of scientists have demonstrated new application of graphene using positive feedback. Using graphene’s electrical conduction, Columbia Univ. engineers have created a nano-mechanical system that can create FM signals. It is, in effect, the world's smallest FM radio transmitter.
Amid a rash of tombstone thefts from cemeteries in Johannesburg, a company will be offering relatives of the deceased a high-tech solution: microchips that can be inserted into the memorial that will sound an alarm and send a text message to their cell phones if it is disturbed.
Invisibility cloaking is no longer the stuff of science fiction: Two researchers at the Univ. of Toronto have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different objects. The team designed and tested a new approach to cloaking—by surrounding an object with small antennas that collectively radiate an electromagnetic field. The radiated field cancels out any waves scattering off the cloaked object.
Twitter clips human thoughts to a mere 140 characters. Animals’ scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them. Recent research show that the detailed scent posts of hyenas are, in part, products of symbiotic bacteria, microbes that have a mutually beneficial relationship with their hosts.
Carnegie Mellon University computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites. This new type of password, dubbed a GOTCHA, would be suitable for protecting high-value accounts, such as bank accounts, medical records and other sensitive information.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability.
Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices.
In a demonstration at the Vienna Univ. of Technology in Austria, scientists have shown that light can be switched between two fiber optic cables with just a single rubidium atom. The breakthrough relies on light capture devices called “bottle resonators”. The switch could enable quantum phenomena to be used for information and communication technology.
A new market study forecasts that the global market for driver monitoring systems will reach 64.8 million units by the end of 2020 with the majority of shipments being accounted for in vehicles sold in the Asia-Pacific region. A major 2013 is that these systems are migrating from the luxury brands like Volvo and Mercedes-Benz to more mass market models.
In the early morning hours of Oct. 18, NASA’s Lunar Laser Communication Demonstration made history, transmitting data from lunar orbit to Earth at a rate of 622Mbps. That download rate is more than six times faster than previous state-of-the-art radio systems flown to the moon.
Semiconductor Research Corporation (SRC) has launched a new research program on hybrid bio-semiconductor systems that they hope will provide insights and opportunities for future information and communication technologies. The Semiconductor Synthetic Biology (SSB) program will initially fund research at six universities.
For those wanting to keep their distance from health threats like E. coli-contaminated lettuce or the flu, there are two upcoming apps for that. Pacific Northwest National Laboratory hosted a competition last summer where graduate students used Android development tools and web-based analytics to design mobile apps that could help fight the threats of food-related illnesses and the flu.
European Union lawmakers on Monday adopted sweeping new data protection rules to strengthen online privacy, and sought to outlaw most data transfers to other countries' authorities to prevent spying. The draft regulation was beefed up after Edward Snowden's leaks about allegedly widespread U.S. online snooping, and the legislation is poised to have significant implications for U.S. Internet companies.
