Confined, insensitive light could improve lasers, solar cells
Cheaper and more efficient photonic devices, such as lasers, optical fibers, and other light sources, may be possible with confined light that is unaffected by imperfections in the material that confines it, according to new research.... full story »

New Technique Makes It Easier to Etch Semiconductors
Creating semiconductor structures for high-end optoelectronic devices just got easier, thanks to University of Illinois researchers.... full story »

Boron Nanoribbons Reveal Surprising Thermal Properties in Bundles
Size matters… but apparently so does shape -- when it comes to conducting heat in very small spaces.... full story »

New Particle at Large Hadron Collider Discovered by ATLAS Experiment
Researchers from the University of Birmingham and Lancaster University, analysing data taken by the ATLAS experiment, have been at the centre of what is believed to be the first clear observation of a new particle at the Large Hadron Collider.... full story »

Chemists Solve an 84-Year-Old Theory On How Molecules Move Energy After Light Absorption
The same principle that causes figure skaters to spin faster as they draw their arms into their bodies has now been used by Michigan State University researchers to understand how molecules move energy around following the absorption of light.... full story »

New Method for Enhancing Thermal Conductivity Could Cool Computer Chips, Lasers and Other Devices
The surprising discovery of a new way to tune and enhance thermal conductivity -- a basic property generally considered to be fixed for a given material -- gives engineers a new tool for managing thermal effects in smart phones and computers... full story »

Targeted Proton Transfer Within a Molecule: Smallest Conceivable Switch
For a long time miniaturization has been the magic word in electronics. Dr. Willi Auwaerter and Professor Johannes Barth, together with their team of physicists at the Technische Universitaet Muenchen (TUM), have now presented a novel molecular switch in the journal Nature Nanotechnology. ... full story »

Possible Hints of Higgs Boson Remain in Latest Analyses, Physicists Say
Two experiments at the Large Hadron Collider have nearly eliminated the space in which the Higgs boson could dwell, scientists announced in a seminar held at CERN Dec. 13.... full story »

Trillion-Frame-Per-Second Video: Researchers Have Created an Imaging System That Makes Light Look Slow
MIT researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That's fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle's bottom.... full story »

Gone With the Wind: Why the Fast Jet Stream Winds Cannot Contribute Much Renewable Energy After All
The assumption that high jet steam wind speeds in the upper atmosphere correspond to high wind power has now been challenged by researchers of the Max Planck Institute for Biogeochemistry in Jena, Germany.... full story »

New Switch Could Improve Electronics
Researchers at the University of Pittsburgh have invented a new type of electronic switch that performs electronic logic functions within a single molecule.... full story »

NMR Used to Determine Whether Gold Nanoparticles Exhibit 'Handedness'
Carnegie Mellon University's Roberto R. Gil and Rongchao Jin have successfully used NMR to analyze the structure of infinitesimal gold nanoparticles, which could advance the development and use of the tiny particles in drug development.... full story »

Measuring Living Cells' Mechanical Properties: Technology Could Diagnose Human Disease, Shed Light On Biological Processes
Researchers are making progress in developing a system that measures the mechanical properties of living cells, a technology that could be used to diagnose human disease and better understand biological processes.... full story »

A Hidden Order Unraveled: Microscopic Views On Quantum Fluctuations
Fluctuations are fundamental to many physical phenomena in our everyday life, such as the phase transitions from a liquid into a gas or from a solid into a liquid.... full story »

Atoms Dressed With Light Show New Interactions, Could Reveal Way to Observe Enigmatic Particle
