Quantum mechanics offers the potential to create absolutely secure telecommunications networks by harnessing a fundamental phenomenon of quantum particles. Now, a team of Stanford University physicists has demonstrated a crucial first step in creating a quantum telecommunications device that could be built and implemented using existing infrastructure.
As many WiFi users know, WiFi performance is often poor in areas where there are a lot of users, such as airports or coffee shops. But researchers at North Carolina State University have developed a new software program, called WiFox, which can be incorporated into existing networks and expedites data traffic in large audience WiFi environments—improving data throughput by up to 700%.
Toyota Motor Corp. is testing car safety systems that allow vehicles to communicate with each other and with the roads they are on in a just completed facility in Japan. The size of three baseball stadiums, the Intelligent Transport System site hosts a fleet of cars that receive information from sensors and transmitters installed on the streets. The sensors help to minimize the risk of accidents in situations such as missing a red traffic light, cars advancing from blind spots, and pedestrians crossing the street.
Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The research team was able to amplify the noisy quantum state of a single photon subjected to loss, without adding noise in the process; in fact, their amplification reduced the noise in the quantum state.
A new iPhone app developed at the University of Michigan lets migraine or facial pain patients easily track and record their pain, which in turn helps the treating clinician develop a pain management plan.
The modern masses can now listen to what experts say is the oldest playable recording of an American voice and the first-ever capturing of a musical performance, thanks to digital advances that allowed the sound to be transferred from flimsy tinfoil to computer. The 78-second recording was originally made on a Thomas Edison-invented phonograph, and features both music and the first recorded blooper.
It's scratchy, lasts only 78 seconds and features the world's first recorded blooper. The modern masses can now listen to what experts say is the oldest playable recording of an American voice and the first-ever capturing of a musical performance, thanks to digital advances that allowed the sound...
Researchers at Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator.
Through a new website unveiled Wednesday, Google is opening a virtual window into the secretive data centers where an intricate maze of computers process Internet search requests, show YouTube video clips, and distribute email for millions of people. The photographic access to Google's data centers coincides with the publication of a Wired magazine article about how the company builds and operates them.
Light might one day be used to cool the materials through which it passes, instead of heating them, thanks to a breakthrough by engineers at Lehigh and Johns Hopkins Universities. The discovery could lead to smaller, lighter, and cheaper communication devices with faster switching times, increased output, and higher operating voltages.
Scientists have pieced together the sequence of events of the farthest touchdown a man-made spacecraft has ever made on an alien world. Their work in tracking the bounces, wobbles, and skids the probe made before coming to rest on Titan reveals new clues about the Saturn moon’s surface and helps plan future missions to moons and planets.
After leading mass spectrometer manufacturers agreed to license technology that has enabled researchers to develop software allows scientists to easily use and share research data collected across proprietary instrument platforms. Called the ProteoWizard Toolkit, this cross-platform set of libraries and applications is expected to bolster large-scale biological research and help improve the understanding of complex diseases like cancer.
Silicon is used in components, e.g. filters or deflectors, for telecommunications. So far, however, all these components have been flat, or 2D. Researchers have developed a new etching method for these structures that results 3D microstructures in silicon. Suitable for fiber optic communications, their optical properties are adjustable at the micrometer scale.
Design for remotely monitoring large infrastructures, the longest fiber-optic sensor network yet designed would measure 250 km in length and be equipped with multiplexing technology to allow multiple information channels to be carried. Theorized by a researcher in Spain, the network would allow long-distance analysis with requiring a power source for the sensors.
Digital cameras and camcorders deliver high resolution film sequences that are several gigabytes in size. These can take several minutes to transfer wirelessly to your home computer via Bluetooth. A researcher in Germany has come up with a speedier alternative: a “multi-gigabit communication module” that is six times faster than a USB cable.
A Purdue University physicist, Leonid Rokhinson, has observed evidence of long-sought Majorana fermions, special particles that could unleash the potential of fault-tolerant quantum computing. Rokhinson led a team that is the first to successfully demonstrate the fractional a.c. Josephson effect, which is a signature of the particles.
A prototype sensor array built by Massachusetts Institute of Technology engineers can be worn on the chest and automatically maps the wearer’s environment, recognizing movement between floors. The prototype system is envisioned as a tool to help emergency responders coordinate disaster response.
Former and current University of Southern California Dornsife physicists have led a study that represents the first, quantitative account of the universal features of disordered bosons, or quantum particles, in magnetic materials. The study broadens our understanding of quantum mechanics and challenges accepted predication in quantum theory.
For airline passengers who dread bumpy rides to mountainous destinations, help may be on the way. A new turbulence avoidance system, developed by the National Center for Atmospheric Research, has for the first time been approved for use at a U.S. airport and can be adapted for additional airports in rugged settings across the United States and overseas.
A new pediatric medical devices being developed by Georgia Institute of Technology and Emory University could make life easier for parents who have rushed to the doctor with a child screaming from an ear infection. Soon, parents may be able to skip the doctor's visit and receive a diagnosis without leaving home by using Remotoscope, a clip-on attachment and software app that turns an iPhone into an otoscope.
Designed to improve the way businesses manage the scientific innovation lifecycle, the new Accelrys Process Management and Compliance Suite unifies Accelrys Inc.’s lifecycle management software offerings, covering the ground between product development and process execution. It is geared to help companies bring products to market faster and at a lower cost, while meeting critical quality and regulatory compliance objectives.
Developed by a company in San Diego, a new automated system that lets consumers trade in cell phones and mobile devices for reimbursement or recycling relies artificial intelliigence and sophisticated machine vision diagnostics. The building blocks for the ecoATM have existed for many years, but none, until now, have been applied to the particular problem of consumer recycling.
Researchers from in Zurich have literally created a “cell phone” from reprogrammed mammalian cells. Using suitable signal molecules and “devices” constructed from biological components, including genes and proteins, the researchers have achieved a synthetic two-way communication system inside a biological cell that also responds to concentration differences in the signal molecules.
The NASA Goddard Space Flight Center has awarded a SBIR Phase II program to Tahoe RF Semiconductor Inc. for developing a miniaturized Radiation Hardened Beam-Steerable GPS Receiver Front End for NASA spacecrafts.
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.
