Measuring each point of a beam of light
If you want to get the greatest benefit from a beam of light-whether to detect a distant planet or to remedy an aberration in the human eye-you need to be able to measure it.... full story »

New photodetector could improve night vision, thermal sensing and medical imaging
Using graphene, engineers have invented a new type of photodetector that can work with more types of light than its current state-of-the-art counterparts.... full story »

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 »

Paint-On Solar Cells Developed
Imagine if the next coat of paint you put on the outside of your home generates electricity from light -- electricity that can be used to power the appliances and equipment on the inside.... 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 »

Discovery of a 'Dark State' Could Mean a Brighter Future for Solar Energy
The efficiency of conventional solar cells could be significantly increased, according to new research on the mechanisms of solar energy conversion led by chemist Xiaoyang Zhu at The University of Texas at Austin.... full story »

Largest Ever Gas Mix Caught in Ultra-Freeze Trap
A team of scientists have made it easier to study atomic or subatomic-scale properties of the building blocks of matter (which also include protons, neutrons and electrons) known as fermions by slowing down the movement of a large quantity of gaseous atoms at ultra-low temperature.... full story »

New Path to Flex and Stretch Electronics: Artificial Electronic Skin Device Capable of Detecting and Responding to Touch
Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make "smart devices" nearly ubiquitous. ... 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 »
