'High Q' NIST nanowires may be practical oscillators
Nanowires grown at the National Institute of Standards and Technology (NIST) have a mechanical "quality factor" at least 10 times higher than reported values for other nanoscale devices such as carbon nanotubes, and comparable to that of commercial quartz crystals. view more (2007-11-28)
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)
Scientists create world's most efficient light-bulb
Scientists have successfully produced the most efficient light bulb ever - but on the microscopic scale. Researchers at Trinity College, Dublin have discovered a technique which significantly improves the output of light from quantum dots, and also allows their light to be focussed and manipulated easily. Their findings are published today in the... view more... (2003-08-27)
Latest generation lineal accelerator for radiotherapy
The Cancer Department at the la University of Navarra University Hospital has acquired a Siemens, latest-generation lineal accelerator. This is the first centre in Spain to install this advanced radiotherapy apparatus which is equipped with multilaminas, minimultilaminas and portal vision. view more (2005-05-17)
Faster than ever seen before - speeding electrons will be snapped by new UK attosecond 'camera'
Ultrafast lasers helping to make some of the shortest pulses of light ever seen in the UK will be at the heart of a new system to capture the movements of electrons as they whizz around the nucleus of atoms. A UKP3.5 million research grant from the UK Research Councils' Basic Technology Programme announced today has been awarded to a team of... view more... (2003-01-15)
Electrons travel through proteins like urban commuters
For Duke University theoretical chemist David Beratan, the results of his 15 years of studying how electrons make their way through some important protein molecules can be summed up with an analogy: how do big city dwellers get from here to there? view more (2007-02-02)
40 Years of Research with Synchrotron Radiation at DESY
On Wednesday, May 19, starting at 1.30 p.m., the DESY research center will celebrate the anniversary of a very special kind of light: For 40 years, scientists have been conducting research with so-called synchrotron radiation at DESY - i.e. light with exceptional properties generated at accelerators. "The first measurements with the light... view more... (2004-05-19)
Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small. view more (2006-07-17)
NIST/Maryland Researchers Demonstrate 'Quantum Data Buffering' Scheme
Pushing the envelope of Albert Einstein's "spooky action at a distance," known as entanglement, researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland have demonstrated a "quantum buffer," a technique that could be used... view more...

Researchers image molecular motor structural changes
An international team of researchers has shed new light on how tiny molecular motors that transport materials within cells generate the energy that powers their movements. view more (2006-09-15)
Curtain May be Closing on Scientific Water Controversy
The curtain may be ringing down on a scientific controversy regarding the structure of water which arose two years ago. view more (2006-06-28)
Trap and zap: Harnessing the power of light to pattern surfaces on the nanoscale
Princeton engineers have invented an affordable technique that uses lasers and plastic beads to create the ultrasmall features that are needed for new generations of microchips. view more (2008-06-19)
Radiologists find a technique to significantly reduce patient radiation dose during CT angiography
Radiologists have discovered that prospective electrocardiogram (ECG) gating allows them to significantly reduce the patient radiation dose delivered during computed tomography (CT) angiography, a common noninvasive technique used to evaluate vascular disease. view more (2009-09-21)
The Lightness of Electrons in a Twisting Metal Crystal
A team of researchers at Princeton University's Materials Research Science and Engineering Center has observed electrons moving through a crystal of bismuth metal behaving like light. view more (2008-07-28)
Putting a Strain on Nanowires Could Yield Colossal Results
In finally answering an elusive scientific question, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials. view more (2009-09-18)
Lasers in car manufacture
Lasers play a key role in modern production - for such tasks as cutting sheet metal to size, welding containers and trimming circuit . But their potential is far from exhausted. The automobile industry is playing a pioneering role in the introduction of new laser types and machining processes. The Fraunhofer Institute for Laser Technology ILT in... view more... (1999-07-01)
First high-resolution images of bone, tooth and shell formation
Researchers at Eindhoven University of Technology (TU/e) have for the first time made high-resolution images of the earliest stages of bone formation. They used the world's most advanced electron microscope to make three-dimensional images of the nano-particles that are at the heart of the process. view more (2009-03-13)
NIST/University Team Records Rare Glimpses of Light from Neutrons
Researchers from the Commerce Department's National Institute of Standards and Technology (NIST) and four universities have made the first experimental observation of rare particles of light emitted during the radioactive decay of the neutron, a key building block of matter. view more (2006-12-21)
Researchers rely on Newton's interference for new experiment
Most people think of Sir Isaac Newton as the father of gravity. But for Lawrence Livermore National Laboratory physicist Henry Chapman and his colleagues, Newton's "dusty mirror" experiment served as a launching pad for them to keenly watch the X-ray induced explosion of microscopic objects. view more (2007-08-09)
McGill physicists find a new state of matter in a 'transistor'
McGill University researchers have discovered a new state of matter, a quasi-three- dimensional electron crystal, in a material very much like those used in the fabrication of modern transistors. view more (2008-10-22)
