What : A new study, supported in part by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, suggests that a combination of mobile technology and remote coaching holds promise in encouraging healthier eating and physical activity behavior in adults. The study focused on the best way to change multiple health behaviors.


NTU and I²R Scientists Invent Revolutionary Chipset for High-speed Wireless Data Transfer

May 29, 2012 5:37 am | by Here is a new microchip that can transfer data the size of 80 MP3 song files (or 250 megabytes) wirelessly between mobile devices, in the flick of a second. | Comments

Data can now be transmitted 1,000 times faster than Bluetooth Or how about transferring a typical 2-hour, 8-gigabyte DVD movie in just half a minute compared to 8.5 hours on Bluetooth? Such unprecedented speeds on the wireless platform are now a reality as scientists from the Nanyang Technological University (NTU) and A*STAR’s Institute for Infocomm Research (I²R) have developed a revolutionary microchip that can transmit large volumes of data at ultra-high speeds of 2 Gigabits per second  (or 1,000 times faster than Bluetooth^).


Sensing the Infrared: Researchers Improve IR Detectors with Single-walled Carbon Nanotubes

May 29, 2012 5:20 am | Comments

Whether used in telescopes or optoelectronic communications, infrared detectors must be continuously cooled to avoid being overwhelmed by stray thermal radiation. Now, a team of researchers from Peking University, the Chinese Academy of Sciences, and Duke University (USA) is harnessing the remarkable properties of single-walled carbon nanotubes (SWNTs) to create highly sensitive, "uncooled" photovoltaic infrared detectors.


Making Microscopic Machines Using Metallic Glass

May 23, 2012 5:30 am | Comments

Researchers in Ireland have developed a new technology using materials called bulk metallic glasses to produce high-precision molds for making tiny plastic components. The components, with detailed microscopically patterned surfaces could be used in the next generation of computer memory devices and microscale testing kits and chemical reactors.


Days of ‘One-size-fits-all’ Cloud Contracts are Numbered, Report Finds

May 23, 2012 5:27 am | Comments

Combined legal and market factors may force online companies to offer more flexible contract terms, suggests new research from Queen Mary, University of London . The paper examines how and why companies providing IT services over the internet, also known as cloud computing, have begun to negotiate standard contract terms to better meet cloud users’ needs, minimise operating risks and address legal compliance obligations.


Bluetooth Baby

Checking the heart of the unborn baby usually involves a stethoscope. However, an inexpensive and accurate Bluetooth fetal heart rate monitoring system has now been developed by researchers in India for long-term home care. Details are reported in a forthcoming issue of the International Journal of Computers in Healthcare .


Protocol Enables Wireless and Secure Biometric Acquisition with Web Services

May 23, 2012 5:21 am | Comments

Researchers at the National Institute of Standards and Technology (NIST) have developed and published a new protocol for communicating with biometric sensors over wired and wireless networks—using some of the same technologies that underpin the web. The new protocol, called WS-Biometric Devices (WS-BD), allows desktops, laptops, tablets and smartphones to access sensors that capture biometric data such as fingerprints, iris images and face images using web services.


Getting in Tune: Researchers Solve Tuning Problem For Wireless Power Transfer Systems

May 23, 2012 5:19 am | by Researchers have shown that it is possible to transmit power wirelessly by using magnetic resonance. Even minor changes in how the transmitter or receiver is tuned, however, can result in faulty power transmission. | Comments

Researchers from North Carolina State University have developed a new way to fine-tune wireless power transfer (WPT) receivers, making the systems more efficient and functional. WPT systems hold promise for charging electric vehicles, electronic devices and other technologies. A new prototype developed at NC State addresses the problem by automatically – and precisely – re-tuning the receivers in WPT systems.


Quantum Computing: The Light At The End Of The Tunnel May Be A Single Photon

May 23, 2012 5:18 am | Comments

Quantum physics promises faster and more powerful computers, but quantum versions of basic logic functions are still needed to bring this technology to fruition. Researchers from the University of Cambridge and Toshiba Research Europe Ltd. have taken one step toward this goal by creating an all-semiconductor quantum logic gate, a controlled-NOT (CNOT) gate.


Navy Pilot Training Enhanced by AEMASE ‘Smart Machine’

May 23, 2012 5:15 am | Comments

Navy pilots and other flight specialists soon will have a new “smart machine” installed in training simulators that learns from expert instructors to more efficiently train their students. Sandia National Laboratories’ Automated Expert Modeling & Student Evaluation (AEMASE, pronounced “amaze”) is being provided to the Navy as a component of flight simulators.


Life-size 3-D Hologram-like Telepods May Revolutionize Videoconferencing in the Future
