Team develops new metamaterial device
An engineered metamaterial proved it can function as a state-of-the-art device in the complex terahertz range of the electromagnetic spectrum, setting a standard of performance for modulating tiny waves of radiation, according to a team of researchers from Boston College, the Los Alamos and Sandia national laboratories, and Boston University. view more (2009-02-25)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)
Nanocups brim with potential
Researchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices. view more (2009-03-16)
Discovery at UAB brings us nearer to making the dream of invisibility true
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light - very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. view more (2009-07-08)
Researchers bridge the 'terahertz gap' with new tunable metamaterial
A frequency-agile metamaterial that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered by a team of researchers from Boston College, Los Alamos National Laboratory and Boston University. view more (2008-04-16)
Scientists step closer to realising invisible technology
A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. view more (2007-05-04)
Engineers create 'optical cloaking' design for invisibility
Researchers using nanotechnology have taken a step toward creating an "optical cloaking" device that could render objects invisible by guiding light around anything placed inside this "cloak." view more (2007-04-03)
Beyond the looking glass
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway. view more (2009-08-13)
New metamaterials that bend light backwards bring invisibility cloaks 1 step closer
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and... view more...

New Technology Opens Up PC World To Disabled
Researchers at the University of Ulster have developed new technology that could revolutionize the quality of life for the disabled. The Look Device allows individuals with severe physical impairments to control the operation of a computer cursor solely with the movement of their eyes. A set of customised spectacles, with built in sensors,... view more... (2002-11-12)
Patients and doctors lack knowledge about adrenaline injections
Patients and general practitioners lack knowledge of how and when to use devices to inject adrenaline after anaphylaxis (severe allergic reactions), finds a study in this week's BMJ. view more (2003-12-03)
The battery-powered Sherpa
Game show candidates might succeed in carrying a washing machine up several flights of stairs in record time - but for normal mortals this represents an enormous feat of strength and patience. People are well advised not to attempt it alone and spare themselves potential back problems - unless of course aided by a transport device. Until now, such... view more... (2001-08-21)
Theoretical blueprint for invisibility cloak reported
Using a new design theory, researchers at Duke University's Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. view more (2006-05-26)
New Technology Reduces Earthquake Damage To Buildings
Imperial College Innovations looks to commercialise new device for improving the structural stability of buildings A novel device that may help to save lives by improving the stability of buildings and preventing structural damage during traumatic events such as earthquakes, has been developed and patented by Imperial College Innovations Limited.... view more...

Device controls electron spin at room temperature
In a breakthrough for applied physics, North Carolina State University researchers have developed a magnetic semiconductor memory device, using GaMnN thin films, which utilizes both the charge and spin of electrons at room temperature. view more (2009-04-07)
Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of the external magnetic field. This exciting new... view more... (2002-08-15)
NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm. view more (2006-12-08)
'Electromagnetic Wormhole' Possible with Invisibility Technology
The team of mathematicians that first created the mathematics behind the "invisibility cloak" announced by physicists last October has now shown that the same technology could be used to generate an "electromagnetic wormhole." view more (2007-10-15)
Technology May Cool The Laptop
