SideBySide projection system enables projected interaction between mobile devices (October 21, 2011) -- Researchers have devised a system called SideBySide that enables animated images from two separate handheld projectors to interact with each other on the same surface. The system, suitable for games, education and a variety of other applications, is self-contained in special handheld devices. No external cameras or other sensors are required, which enables people to use the projectors to interact with each other anywhere and at anytime. ... > full story
Electrochemistry controlled with a plasma electrode (October 21, 2011) -- Engineers have made an electrochemical cell that uses a plasma for an electrode, instead of solid pieces of metal. The technology may open new pathways for battery and fuel cell design and manufacturing, making hydrogen fuel and synthesizing nanomaterials and polymers. ... > full story
Viruses coaxed to form synthetics with microstructures akin to those of corneas, teeth and skin (October 21, 2011) -- Using a simple, single-step process, engineers and scientists have recently developed a technique to direct benign, filamentous viruses called M13 phages to serve as structural building blocks for materials with a wide range of properties. ... > full story
TapSense: Touchscreen technology distinguishes taps by parts of finger (October 21, 2011) -- Smartphone and tablet computer owners have become adept at using finger taps, flicks and drags to control their touchscreens. But researchers have found that this interaction can be enhanced by taking greater advantage of the finger's anatomy and dexterity. By attaching a microphone to a touchscreen, the scientists have shown they can tell the difference between the tap of a fingertip, the pad of the finger, a fingernail and a knuckle. This technology, called TapSense, enables richer touchscreen interactions. ... > full story
The eyes have it: Computer-inspired creativity (October 21, 2011) -- Constraints on creativity imposed by computer-aided design tools are being overcome, thanks to a novel system that incorporates eye-tracking technology. ... > full story
Astronomers explain blue stragglers: How do mysterious stars stay so young? (October 21, 2011) -- Mysterious "blue stragglers" are old stars that appear younger than they should be: they burn hot and blue. Several theories have attempted to explain why they don't show their age, but, until now, scientists have lacked the crucial observations with which to test each hypothesis. Armed with such observational data, astronomers now report that a mechanism known as mass transfer explains the origins of the blue stragglers. ... > full story
Number of Facebook friends linked to size of brain regions, study suggests (October 21, 2011) -- Scientists have found a direct link between the number of "Facebook friends" a person has and the size of particular brain regions. In a new study researchers also showed that the more Facebook friends a person has, the more "real-world" friends they are likely to have. ... > full story
Reading a book versus a screen: Different reading devices, different modes of reading? (October 21, 2011) -- A book or a screen – which of these two offers more reading comfort? There are no disadvantages to reading from electronic reading devices compared with reading printed texts, according to a new study. ... > full story
'Microring' device could aid in future optical technologies (October 21, 2011) -- Researchers have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems and laboratory instruments. ... > full story
Magnetic attraction: Microchip demonstrates concept of 'MRAM for biomolecules' (October 21, 2011) -- Researchers have developed a low-power microchip that uses a combination of microfluidics and magnetic switches to trap and transport magnetic beads. The novel transport chip may have applications in biotechnology and medical diagnostics. ... > full story
New benchtop polymer characterization method developed (October 21, 2011) -- Researchers have developed a new and highly efficient way to characterize the structure of polymers at the nanoscale -- effectively designing a routine analytical tool that could be used by industries that rely on polymer science to innovate new products, from drug delivery gels to renewable bio-materials. ... > full story
Aggregating bandwidth for faster mobile networks (October 21, 2011) -- A new study reveals that the value of mobile spectrum, the capacity to transfer data across mobile networks, is only likely to increase as the demand for data transfer increases. However, it is only those telecommunications companies that bought up in government auctions the inexpensive licenses to operate at particularly frequencies of the spectrum that will be in strong position to dominate in the consumer and enterprise markets. ... > full story
