According to scientists at Carnegie Mellon Univ. and Microsoft Research, the same 3-D printing process used to produce an object can simultaneously generate an internal, invisible tag. These internal tags, which the have been dubbed InfraStructs, can be read with an imaging system using terahertz radiation. As terahertz technology develops, these tags could have many applications.
Researchers in Switzerland have developed a live-cell fluorescent labeling that makes bacterial cell-to-cell communication pathways visible. The communication between bacterial cells is essential in the regulation of processes within bacterial populations, such as biofilm development.
GOJO Industries, a maker of hand hygiene and skin health and inventors of Purell Hand Sanitizer, conducted an independent research study at the John Peter Smith Hospital in Fort Worth, Texas to determine the impact on hand hygiene compliance rates when the hospital hand hygiene program included an electronic compliance activity monitoring system. The research showed a 92% hand hygiene improvement.
Researchers at Columbia Univ. School of Nursing have found that electronic health record (EHR) system to automate the immunization data shared between health providers and public health agencies enables physicians to assist individual patients faster and more effectively, while also providing more immediate, cohesive community data to the agencies tasked with promoting public health.
Antennas that are capable of transmitting radio waves turn components into intelligent objects. Researchers in Germany have now found a way to embed these antennas in fiber composites. As a result, the technology also works with carbon and glass fibers.
China's population of Internet users has grown to 591 million, driven by a 20% rise over the past year in the number of people who surf the Web from smartphones and other wireless devices, an industry group reported Wednesday. The rise of Web use has driven the growth of new Chinese industries from online shopping and microblogs to online video.
Researchers at the Univ. of Washington say one of the reasons face- and eye-recognition systems haven’t taken off is because the user’s experience often isn’t factored into the design. Their recent study, one of the first in the field to look at user preferences, found that speed, accuracy and choice of error messages were all important for the success of an eye-tracking system.
A Personal Identity Verification (PIV) card is a government-issued smart card used by federal employees and contractors to access government facilities and computer networks. To assist agencies seeking stronger security and greater operational flexibility, NIST has made several modifications to the previous version of Biometric Data Specification for PIV cards.
American information is so valuable, experts say, that no amount of global outrage over secret U.S. surveillance powers would cause Britain, Canada, Australia and New Zealand to ditch their collaborative spying arrangement: the Five Eyes. Revelations from NSA leaker Edward Snowden, they say, are unlikely to stop or even slow the global growth of secret-hunting—an increasingly critical factor in the security and prosperity of nations.
By pinpointing locations on Earth from space, GPS systems have long shown drivers the shortest route home and guided airline pilots across oceans. Now, by figuring out how messed up GPS satellite signals get when bouncing around in a storm, researchers have found a way to do something completely different with GPS: measure and map the wind speeds of hurricanes.
Research is growing with high-tech gadgets that promise new safety nets for seniors determined to live on their own for as long as possible. Motion sensors on the wall and a monitor under the mattress one day might automatically alert loved ones to early signs of trouble well before an elderly loved one gets sick or suffers a fall.
In DARPA’s Virtual Robotics Challenge, 28 competing teams applied software of their own design to a simulated robot in an attempt to complete a series of tasks that are prerequisites for more complex activities. Just seven teams advanced to the next round, which was unveiled last week at Boston Dynamics: ATLAS, one of the most advanced humanoid robots ever built.
In an apple seed-sized pellet of glass, Univ. of Michigan engineering researchers have packed seven devices that together could potentially provide navigation in the absence of the satellite-based Global Positioning System (GPS.) Space-based GPS is far from fail-proof. It doesn't work indoors, near tall buildings or in heavy cloud cover; and it's relatively easy to jam, researchers say.
A low-cost system developed in Singapore, based on the principles of vibration and imaging, can turn a whiteboard, glass window or even a wooden tabletop into a responsive, touch-sensitive surface. According to its developers, retrofitting the system onto existing flat-panel TVs will transform them into new, touch-sensitive display screens.
Landing an airplane on an aircraft carrier deck is one of the most difficult tasks a pilot is asked to do. On Wednesday, the Navy will attempt to accomplish the same task with a drone. If all goes as planned, a successful landing of the X-47B experimental aircraft will mean the Navy can move forward with its plans provide around-the-clock surveillance and strike capability.
With a 3-D printer, a petri dish and some cells from a cow, Princeton Univ. researchers are growing synthetic ears that can receive—and transmit—sound. The 3-D ear is not designed to replace a human one, though; the research is meant to explore a new method of combining electronics with biological material.
Researchers of the Univ. of Stuttgart have achieved a new world record in coupling efficiency between optical fibers and integrated silicon waveguides. The breakthrough, which resulted in a coupling efficiency of 87%, was based on newly developed aperiodic grating coupler structures optimized at the nanoscale.
Honda's robotics technology, although among the most advanced for mobility, has come under fire as lacking practical applications and being little more than an expensive toy. The latest example is its walking, talking interactive Asimo robot, which is now acting as a museum guide in Tokyo. In addition to glitches that have interrupted its operation, it lacks voice recognition.
Apple Inc. has applied for a trademark in Japan for "iWatch" as rumors suggest it may be developing a smart wrist watch. The company is rumored to be working on a smart watch that would run on a version of the operating system used by its iPhone and iPad.
The saga of Edward Snowden and the NSA makes one thing clear: The United States' central role in developing the Internet and hosting its most powerful players has made it the global leader in the surveillance game. Other countries, from dictatorships to democracies, are also avid snoopers, tapping into the high-capacity fiber optic cables to intercept Internet traffic.
Digital systems are an everyday routine for more and more passengers, and even Internet is now available. But pilots are largely cut off from this development with a system that is separate and largely analog. Under development in Germany is a new system that will digitally transmit air traffic and weather communications with the ground and via satellite at high speeds.
Hospitals have fretted for years over how to make sure doctors, nurses and staff keep their hands clean, but with only limited success. Now, some are turning to technology—beepers, buzzers, lights and tracking systems that remind workers to sanitize, and chart those who don't.
Researchers have long attempted to build a device capable of seeing people through walls. However, previous efforts to develop such a system have involved the use of expensive and bulky radar technology that uses a part of the electromagnetic spectrum only available to the military. Now a system being developed at the Massachusetts Institute of Technology can spot people in different rooms using low-cost Wi-Fi technology.
In secure communications, which can rely on quantum information contained in one of four wavelength phase states, wrong is worse than "I don't know." Researchers at NIST and the Joint Quantum Institute have built a single-photon detector that avoids this problem, making highly accurate measurements of incoming photons while knowing when not to give a conclusive answer.
The world's first space conversation experiment between a robot and humans is ready to be launched. Developers from the Kirobo project, named after "kibo" or hope in Japanese and "robot," gathered in Tokyo Wednesday to demonstrate the humanoid robot's ability to talk.
