Apr. 28, 2015 — Scientists and engineers have reported the direct detection of cyclotron radiation from individual electrons. They used a specially developed spectroscopic method that allowed them to measure the ... read more

Apr. 28, 2015 — First collisions of protons at the world's largest science experiment should start the first or second week of June. The LHC restarted is second run in early April. There are no significant ... read more

Apr. 28, 2015 — Scientists have developed an optical method for remotely measuring sound pressure inside a fully anechoic chamber which is the first to provide direct traceability to the SI base ... read more

Apr. 28, 2015 — A new technique for visualizing the rapidly changing electronic structures of atomic-scale materials as they twist, tumble and traipse across the nanoworld is taking shape. Researchers have for the ... read more

Quantum Particles at Play: Game Theory Elucidates the Collective Behavior of Bosons

Apr. 28, 2015 — Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists have shown how bosons, which like to enter the ... read more

Apr. 28, 2015 — New nanoscale blueprints for low-energy, stable gold nanoclusters could help develop new cancer drugs or mitigate carbon monoxide ... read more

When Mediated by Superconductivity, Light Pushes Matter Million Times More

Apr. 28, 2015 — When a mirror reflects light, it experiences a slight push. This radiation pressure can be increased considerably with the help of a small superconducting island. The finding paves a way for the ... read more

First Quantum Evidence of System-Shrinking Negative Electronic Compressibility in Novel Insulator

Apr. 27, 2015 — Add water to a half-filled cup and the water level rises. This everyday experience reflects a positive material property of the water-cup system. But what if adding more water lowers the water level ... read more

Apr. 27, 2015 — Scientists have dramatically improved the performance of graphene by encapsulating it in boron nitride. They’ve now shown they can similarly improve the performance of another 2D material, ... read more

Apr. 27, 2015 — The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange ... read more

Artificial Spin Ice: A New Playground to Better Understand Magnetism

Apr. 27, 2015 — For the first time, nanomagnet islands or arrays were arranged into an exotic structure (called “shakti”) that does not directly relate to any known natural material. The “shakti” artificial ... read more

Apr. 24, 2015 — Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. They demonstrate that an approach for generating terahertz waves using ... read more

Improvement to Global Software Standard for Analyzing Fusion Plasmas

Apr. 24, 2015 — The gold standard for analyzing the behavior of fusion plasmas may have just gotten better. Computer scientists have just updated the worldwide computer program known as TRANSP to better simulate the ... read more

Apr. 23, 2015 — Scientists use a novel form of nanotechnology to create a positionable silver cluster with DNA-programmed tunable fluorescent ... read more

Apr. 23, 2015 — Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a new technique. Scientists used quantum correlated beams of light to overcome the fundamental detection limit of ... read more

Apr. 23, 2015 — The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. A team of neuroscientists now reports a perceptual illusion of having an invisible ... read more

Apr. 23, 2015 — Albert Einstein tells us that clocks run slower the deeper they are in the gravitational potential well of a mass – the closer they are to a heavenly body, for example. This effect is described by ... read more

Apr. 23, 2015 — Scientists have created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the 'gate sensor' and could be ... read more

Reducing Big Data Using Ideas from Quantum Theory Makes It Easier to Interpret

Apr. 23, 2015 — Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been  represented  ... read more

Apr. 23, 2015 — Taking child's play with building blocks to a whole new level-the nanometer scale-scientists have constructed 3D "superlattice" multicomponent nanoparticle arrays where the arrangement ... read more
