Fiber-based nanotechnology could power electronic devices
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy.
Engineers announce record-setting high-frequency circuit
Engineering researchers from the University of Florida and Texas Instruments have crafted the world's highest-frequency circuit made with a common type of semiconductor transistor, a step that could slash the price of detectors useful in earlier cancer detection and quicker pollution spotting.
Learning about brains from computers, and vice versa
For many years, Tomaso Poggio's lab at MIT ran two parallel lines of research. Some projects were aimed at understanding how the brain works, using complex computational models. Others were aimed at improving the abilities of computers to perform tasks that our brains do with ease, such as making sense of complex visual images.
Scientists using laser light to detect potential diseases via breath
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.
Cosmic ray effect on microchips benefits from accelerated neutron testing
UK neutron scientists are tackling the challenge of cosmic radiation and its damaging effect on sensitive microchips in the aviation industry in the drive to develop more robust electronic equipment. Accelerated testing of microelectronic components at the Science and Technology Facilities Council's (STFC) world leading ISIS neutron research centre replicates the effect of thousands of hours of flying time in just a few minutes.
Lensless camera uses x-rays to view nanoscale materials and biological specimens
X-rays have been used for decades to take pictures of broken bones, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators have developed a lensless X-ray technique that can take images of ultra-small structures buried in nanoparticles and nanomaterials, and features within whole biological cells such as cellular nuclei.
Astronomy technology brings nanoparticle probes into sharper focus
While pondering the challenges of distinguishing one nano-sized probe image from another in a mass of hundreds or thousands of nanoprobes, researchers at Georgia Tech and Emory University made an interesting observation. The tiny, clustered dots of light looked a lot like a starry sky on a clear night.
Killer military robots pose latest threat to humanity
In a keynote address to the Royal United Services Institute (RUSI), Professor Noel Sharkey, from the University's Department of Computer Science, will express his concerns that we are beginning to see the first steps towards an international robot arms race. He will warn that it may not be long before robots become a standard terrorist weapon to replace the suicide bomber.
Engineering the world's fastest swimsuit
A highly specialised computer modelling technique developed at The University of Nottingham has been instrumental in the design of a revolutionary new swimsuit which is now being hailed as the fastest in the world.
Attack on computer memory reveals vulnerability of widely used security systems
A team of academic, industry and independent researchers has demonstrated a new class of computer attacks that compromise the contents of "secure" memory systems, particularly in laptops.

Wii bit of technology aids medical education
Practicing medicine is complicated, serious business. But learning to practice medicine – even surgical techniques – can be aided by some simple games designed for fun.
Steps towards warship invisibility
Naval warships might look like all-powerful vessels but they are also highly vulnerable to being spotted by the enemy. That fear of being detected has led the military to develop new stealth technologies that allow ships to be virtually invisible to the human eye, to dodge roaming radars, put heat-seeking missiles off the scent, disguise their own sound vibrations and even reduce the way they distort the Earth's magnetic field, as senior lecture in remote sensing and sensors technology at Britannia Royal Navy College, Chris Lavers, explains in March's Physics World.
Magnetic levitation gives computer users sense of touch
Computers, long used as tools to design and manipulate three-dimensional objects, may soon provide people with a way to sense the texture of those objects or feel how they fit together, thanks to a haptic, or touch-based, interface developed at Carnegie Mellon University.
Future 'quantum computers' will offer increased efficiency... And risks
An unusual observation in a University of Central Florida physics lab may lead to a new generation of "Quantum Computers" that will render today's computer and credit card encryption technology obsolete.
One million trillion flops per second targeted by new institute for advanced architectures
Preparing groundwork for an exascale computer is the mission of the new Institute for Advanced Architectures, launched jointly at Sandia and Oak Ridge national laboratories.
TU delft tests windmill for seawater desalination
A traditional windmill which drives a pump: that is the simple concept behind the combination of windmill/reverse osmosis developed by the Delft University of Technology (TU Delft) in The Netherlands. In this case, it involves a high-pressure pump which pushes water through a membrane using approximately 60 bar. This reverse osmosis membrane produces fresh water from seawater directly. The windmill is suited for use by, for instance, small villages in isolated, dry coastal areas.
Bringing second life to life: researchers create character with reasoning abilities of a child
Today's video games and online virtual worlds give users the freedom to create characters in the digital domain that look and seem more human than ever before. But despite having your hair, your height, and your hazel eyes, your avatar is still little more than just a pretty face.
Naval research laboratory to design lunar telescope to see into the dark ages
A team of scientists and engineers led by the Naval Research Laboratory (NRL) will study how to design a telescope on the Moon for peering into the last unexplored epoch in the Universe's history. NASA has announced that it will sponsor a series of studies focusing on next-generation space missions for astronomy. These studies will contribute to the Decadal Survey, an effort undertaken every 10 years by astronomers and physicists to help establish priorities for future research directions in astronomy and astrophysics. The upcoming Decadal Survey occurs over the next two years.
Tiny torrents
Engineers harnessing the same physical property that drives silent household air purifiers have created a miniaturized device that is now ready for testing as a silent, ultra-thin, low-power and low maintenance cooling system for laptop computers and other electronic devices.
ORNL study shows hybrid effect on power distribution
A growing number of plug-in hybrid electric cars and trucks could require major new power generation resources or none at all -depending on when people recharge their automobiles.
