Scientists use pixels to ease amputees' pain
Scientists at The University of Manchester are using 3D computer graphics to combat the pain suffered by amputees.
New technique breaks nanometer barrier in x-ray microscopy
A new X-ray microscopy technique that observes molecular-scale features less than a nanometer in height has been developed by scientists at the U.S. Department of Energy's Argonne National Laboratory in collaboration with Xradia, Inc. By combining X-ray reflection with high-resolution X-ray microscopy, scientists can now study interactions at the nanometer-scale, where materials often exhibit new properties. A better understanding of interactions at the nanoscale promises to help cure the sick, protect the environment and make the nation more secure.
Cloudy day won't rain on laser communications
Just as clouds block the sun, they interfere with laser communications systems, but Penn State researchers are using a combination of computational methods to find the silver lining and punch through the clouds.
Dut shines light on atomic transistor
Researchers from Delft University of Technology and the FOM Foundation (Fundamental Research on Matter) have successfully measured transport through a single atom in a transistor.
Scrap tires can be used to filter wastewater
Every year, the United State produces millions of scrap tires that clog landfills and become breeding areas for pests. Finding adequate uses for castoff tires is a continuing challenge and illegal dumping has become a serious problem throughout the nation.
Math model could aid natural gas production
MIT engineers have developed a mathematical model that could help energy companies produce natural gas more efficiently and ensure a more reliable supply of this valuable fuel.
Robot adapts to injury
Nothing can possibly go wrong ... go wrong ... go wrong ... The truth behind the old joke is that most robots are programmed with a fairly rigid "model" of what they and the world around them are like. If a robot is damaged or its environment changes unexpectedly, it can't adapt.
Pilot study succesful in taming allergic reactions to food
The most powerful tunable laser in the world just shattered another power record: the Free-Electron Laser (FEL), supported by the Office of Naval Research and located at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), produced a 14.2 kilowatt (kW) beam of laser light at an infrared wavelength of 1.61 microns on October 30.
Researcher gives robotic surgery tools a sense of touch
By substituting mechanical instruments for human fingers, robotic tools give surgeons a new way to perform medical procedures with great precision in small spaces. But as the surgeon directs these tools from a computer console, an important component is lost: the sense of touch.
U of t tool circumvents Internet censorship
With the Dec. 1 release of psiphon software, developed by U of T's Citizen Lab, people around the world will have access to a free tool enabling them to circumvent Internet censorship.

Engineer focuses on the mechanics of better bullet proofing
Body armor with greater ballistics resistance is the aim of the research being carried out by Youqi Wang, associate professor of mechanical engineering at Kansas State University, with support from two U.S. Department of Defense agencies.
Pure carbon nanotubes pass first in vivo test
In the first experiments of their kind, researchers at Rice University and The University of Texas M. D. Anderson Cancer Center have determined that carbon nanotubes injected directly into the bloodstream of research lab animals cause no immediate adverse health effects and circulate for more than one hour before they are removed by the liver.
Geologists provide new evidence for reason behind rise of life in cambrian period
Geologists have uncovered evidence in the oil fields of Oman that explains how Earth could suddenly have changed 540 million years ago to favor the evolution of the single-celled life forms to the multicellular forms we know today.
Breakthrough in magnetic devices could make computers more powerful
Scientists have created novel 'spintronic' devices that could point the way for the next generation of more powerful and permanent data storage chips in computers.
Flexible electronics advance boosts performance, manufacturing
Flexible electronics made with organic, or carbon-based, transistors could enable technologies such as low-cost sensors on product packaging and "electronic paper" displays as thin and floppy as a placemat. But the best mass-producible organic transistors so far have only milquetoast performance, and products using them have yet to come to market. In a study published in the Dec. 14 issue of the journal Nature, researchers at Stanford and the University of California-Los Angeles point the way toward manufacturing truly useful flexible electronics with high-performance organic transistors.
New transistor technology may power next microelectronic devices
MIT engineers have demonstrated a technology that could introduce an important new phase of the microelectronics revolution that has already brought us iPods, laptops and much more.
Researchers create DNA logic circuits that work in test tubes
Computers and liquids are not very compatible, as many a careless coffee-drinking laptop owner has discovered. But a new breakthrough by researchers at the California Institute of Technology could result in future logic circuits that literally work in a test tube--or even in the human body.
Computer scientists unravel 'language of surgery'
Borrowing ideas from speech recognition research, Johns Hopkins computer scientists are building mathematical models to represent the safest and most effective ways to perform surgery, including tasks such as suturing, dissecting and joining tissue.
Butterfly wing is template for photonic structures
By replicating the complex micron- and nanometer-scale photonic structures that help give butterfly wings their color, researchers have demonstrated a new technique that uses biotemplates for fabricating nanoscale structures that could serve as optical waveguides, optical splitters and other building blocks of photonic integrated circuits.
World's fastest transistor approaches goal of terahertz device
Scientists at the University of Illinois at Urbana-Champaign have again broken their own speed record for the world's fastest transistor. With a frequency of 845 gigahertz, their latest device is approximately 300 gigahertz faster than transistors built by other research groups, and approaches the goal of a terahertz device.
