A new way of measuring sea level using satellite navigation system signals, such as GPS, has been implemented by scientists in Sweden. Sea level and its variation can easily be monitored using existing coastal GPS stations, the scientists have shown, and requires just two antennas that measure signals both directly from the satellites and signals reflected off the sea surface.
Researchers at North Carolina State Univ. have developed new modifications for technology that helps pilots of small aircraft avoid midair collisions. The modified tools significantly improved pilot response times in making decisions to avert crashes. At issue are cockpit displays of traffic information (CDTIs). These are GPS displays used by private pilots to track other aircraft in their vicinity.
Culminating a ten-year development effort, Teraphysics Corp. scientists have demonstrated the emission of terahertz light by passing electron beams through a gold coil, smaller in diameter than a human hair, supported by a diamond structure. The detection of a terahertz signal provided proof of concept for Teraphysics’ suite of microfabricated vacuum electronic devices.
Scientists at Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics. Their latest work shows that stacked nanoscale magnetic vortices separated by a thin layer of copper can be driven to operate in unison, potentially producing a powerful signal that could be put to work in new electronics.
In the field of neuromorphic engineering, researchers study computing techniques that could someday mimic human cognition. Electrical engineers at the Georgia Institute of Technology recently published a "roadmap" that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer.
In a recent demonstration by researchers in Europe, miniaturized optical frequency comb sources allow for transmission of data streams of several terabits per second over hundreds of kilometers. The results, which showed a data rate of 1.44 TB/sec over 300 km, may contribute to accelerating data transmission in large computing centers and worldwide communication networks.
For optical communication to happen, it is essential to convert electrical information into light, using emitters. On the other end of the optical link, one needs to translate the light stream into electrical signals using detectors. Current technologies use different materials to realize these two distinct functions, but this might soon change thanks to a new discovery by researchers at IBM.
Passwords, gestures and fingerprint scans are all helpful ways to keep a thief from unlocking and using a cell phone or tablet. Cybersecurity researchers from the Georgia Institute of Technology have gone a step further. They’ve developed a new security system that continuously monitors how a user taps and swipes a mobile device.
Underwater sounds detected by a ship searching the southern Indian Ocean for the missing Malaysia Airlines jet are consistent with the pings from aircraft black boxes, an Australian official says Monday, dubbing it "a most promising lead" in the month-long hunt for the vanished plane.
Inspired by human biology, a revolutionary new method of encrypting confidential information has been patented by scientists. This discovery could transform daily life which is reliant on secure electronic communications for everything from mobiles to sensor networks and the internet.
Results from a recent applied science study at Caltech support the idea that waveguides coupled with another quantum particle—the surface plasmon—could also become an important piece of the quantum computing puzzle.
Long before next-generation sequencing technology appeared, clinicians have been taking family histories by jotting down pedigrees: hand-drawn diagrams recording how diseases may recur across generations. Now healthcare providers can create those diagrams digitally on an iPad screen with a few finger taps, during a face-to-face encounter with an individual and his or her family.
A smartphone app for recovering alcoholics that includes a panic button and sounds an alert when they get too close to taverns helped keep some on the wagon, researchers who developed the tool found. The sober app studied joins a host of others that serve as electronic shoulder angels, featuring a variety of options for trying to prevent alcoholics and drug addicts from relapsing.
Microsoft Corp., which has skewered rival Google Inc. for going through customer emails to deliver ads, has acknowledged that it searched emails in a blogger's Hotmail account to track down who was leaking company secrets. John Frank, deputy general counsel for Microsoft, which owns Hotmail, says in a statement that the software company "took extraordinary actions in this case."
A new app developed by researchers the U.K. accurately measures color-based, or colorimetric, tests for use in home, clinical or remote settings, and enables the transmission of medical data from patients directly to health professionals. Called Colorimetrix, the app helps transform any smartphone into a portable medical diagnostic device.
In 2010, researchers demonstrated for the first time that atmospheric information could be captured by an airborne GPS device. Now, a new technique led by a researcher at Scripps Institution of Oceanography stands to improve weather models and hurricane forecasting by detecting precise conditions in the atmosphere through a new GPS system. A first-time demonstration using this system has captured key meteorological data from aircraft.
Researchers are working to enable smartphones and other mobile devices to understand and immediately identify objects in a camera's field of view, overlaying lines of text that describe items in the environment. The innovation could find applications in "augmented reality" technologies like Google Glass, facial recognition systems and robotic cars that drive themselves.
Researchers from North Carolina State Univ. have developed a new, stretchable antenna that can be incorporated into wearable technologies, such as health monitoring devices. The researchers wanted to develop an antenna that could be stretched, rolled or twisted and always return to its original shape, because wearable systems can be subject to a variety of stresses as patients move around.
A new analysis of satellite data reveals a link between dust in North Africa and West Asia and stronger monsoons in India. The study shows that dust in the air absorbs sunlight west of India, warming the air and strengthening the winds carrying moisture eastward. This results in more monsoon rainfall about a week later in India.
The 360-degree views of the Grand Canyon that went live Thursday in Google's Street View map option once were reserved largely for rafters who were lucky enough to board a private trip through the remote canyon, or those willing to pay big bucks to navigate its whitewater rapids. But a partnership with the advocacy group American Rivers has allowed to Google to take its all-seeing eyes down nearly 300 miles of rich geologic history.
Once the stuff of science fiction, driverless cars could be commercially available by decade's end. Under a California law passed in 2012, the DMV must decide by the end of this year how to integrate the autonomous vehicles onto public roads. That means the regulation's writers will post draft language regulations around June, then alter the rules in response to public comment by fall in order to get them finalized by the end of 2014.
The World Wide Web marks its 25th anniversary this year. On Wednesday, its inventor, Tim Berners-Lee, commented about the state of the Internet and about the need to defend principles that have made the Web successful. Named an R&D Scientist of the Year in 1996, Berners-Lee has been a long-time proponent of openness and neutrality on the Web.
FOMO—or the fear of missing out—is a common complaint at the South By Southwest Interactive festival in Austin, Texas each year. It's here, after all, that "Girls" creator Lena Dunham spoke on Monday at the same time that NSA whistleblower Edward Snowden gave a teleconferenced talk. All the while, IBM showed off the capabilities of cognitive computing in a language anyone could understand: food.
Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at the California Institute of Technology.
The nature of science shares striking similarities across many industry verticals.
