Purdue Univ. researchers who developed a new approach to more effectively teach large numbers of engineering students are recommending that the approach be considered for adoption by universities globally. The system, called the Purdue Mechanics Freeform Classroom, allows students to interact with each other and faculty online while accessing hundreds of instructional videos and animations. It has been used for more than two years.
In 2010, telemedicine was used to guide the insertion of a chest tube in a 72-year-old South Dakota farmer who had been pinned by a cow. Physicians in Sioux Falls talked am inexperienced doctor through the steps to stop the bleeding and drain the blood collecting inside the man. It's a system that's gaining wider use across the rural U.S., where there are often few primary care doctors and even fewer emergency rooms.
The potential of terahertz waves has yet to be reached because they are difficult to generate and manipulate. Current sources are large devices that require complex vacuum, lasers and cooling systems. A Northwestern Univ. team is the first to produce terahertz radiation in a simplified system. Their room-temperature, compact, continuous terahertz radiation source is six times more efficient than previous systems.
A cooing, gesturing humanoid on wheels that can decipher emotions has been unveiled in Japan by billionaire Masayoshi Son, who says robots should be tender and make people smile. The machine, called “Pepper”, has no legs, but has gently gesticulating hands. It recently appeared on a stage in a Tokyo suburb along with announcement that it will go on sale in Japan next year for the equivalent of US$1,900.
The need for robust password security has never been more critical than now, as people use smartphones or tablets to pay bills and store personal information. A new Rutgers study shows that free-form gestures can be used to unlock phones and grant access to apps. These gestures are less likely to be observed and reproduced than than traditional methods such as typed passwords.
In the last 10 years, the presence of wireless technology has blossomed in the industrial and manufacturing space, where a multitude of technologies, from Bluetooth to Zigbee to RFID, have been successfully employed to monitor conditions of machinery, products under assembly and the work force.
The ability to adapt to changing situations is critical for today’s labs. Today, many lab equipment systems are designed with the flexibility to accommodate these needs. Time is also of utmost importance, and the ability for a researcher to walk away from their work, or monitor it on the go, is a new standard.
Computer scientists at Microsoft Research and the University of California, San Diego have developed a system, called ParentGuardian, that combines a mobile application and sensor to detect stress in parents. The system, initially tested on parents of children with ADHD, delivers research-based strategies to help decrease stress during emotionally charged interactions with children.
After another year of flat spending in 2013, global investment in R&D is forecast to grow by 3.8% to $1.6 trillion in 2014, according the annual R&D Magazine Global Funding Forecast. In the U.S., federal spending is forecast to increase modestly (1.5%), another promising sign, but it’s fair to say the pressure is still on to do more with less, particularly in Big Pharma where recent R&D cuts have been the most dramatic.
Pharmaceutical companies are constantly seeking ways to improve efficiency in order to increase productivity, all while speeding up innovation and protecting intellectual property (IP). The use of mobile applications (apps) in the laboratory has been investigated as a means to achieve these goals. By allowing scientists to move freely around the laboratory, mobile apps add value to suboptimal processes requiring non-value-added steps.
Scientists at NIST and the Joint Quantum Institute have shown how attempts to "push" part of a light beam past the speed of light results in the loss of the quantum data the light carries. The results could clarify how noise might limit the transfer of information in quantum computers.
A new twist on 3-D imaging technology could one day enable your self-driving car to spot a child in the street half a block away or play “virtual tennis” on your driveway. The new system, developed by researchers at the Univ. of California, Berkeley, can remotely sense objects across distances as long as 30 feet, 10 times farther than what could be done with comparable current low-power laser systems.
One major limitation of augmented reality (AR) devices such as Google Glass is that moving back and forth between a 2-D image on a screen and the 3-D real world can cause eye strain unless the object of focus is far away. A new device under development should make AR technology easier on the eyes for short-distance applications, too, by superimposing 3-D images instead of 2-D.
A demonstration by NASA and MIT engineers last fall showed, for first time, that a data communication technology exists that can provide space dwellers with the connectivity we all enjoy here on Earth. Next month, the team will present the first comprehensive overview of the performance of their laser-based communication uplink between the moon and Earth, which beat the previous record transmission speed last fall by a factor of 4,800.
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.
