Microchip moves information around in 3-D: From left to right, back to front, and up and down

Scientists have created, for the first time, a new type of microchip which allows information to travel in three dimensions. Currently, microchips can only pass digital information in a very limited way -- from either left to right or front to back.

Reconcilable differences: Study uncovers the common ground of scientific opposites

Researchers have developed a mathematical framework that strips away the differences between scientific laws and theories to reveal how the ideas are compatible. They have explained how the mathematical model finds common ground between the famously at-odds physics equations that govern classical and quantum mechanics.

New research embraces laser and sparks cool affair

Bulky and noisy air-conditioning compressors and refrigerators may soon be a thing of the past. With the latest discovery by scientists from Nanyang Technological University (NTU), current cooling systems which uses refrigerant harmful to the ozone layer could be replaced by a revolutionary cooling system using lasers.

Mechanism behind wear at atomic scale

As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically on shape and surface structure, wear affects nanoscale objects more strongly than it does their macroscale counterparts. Now, researchers have experimentally demonstrated one of the mechanisms behind wear at the smallest scale: the transfer of material, atom by atom, from one surface to another.

Generating, sustaining electrical currents with unique properties for information processing closer to reality

Spintronics is a form of signal processing similar to that used in traditional electronics, but it takes advantage of a property of electrons known as spin. Spin is often visualized as an arrow about which the electron rotates, much like a top spinning around its axis. Generating a stream of electrons in which these 'arrows' are all parallel—a so-called spin-polarized current (see image)—is the foundation upon which spintronics is based. Imperfections in a material, however, can easily destroy polarization.

NSAC to recommend closing BNL Relativistic Heavy Ion Collider facility

(Phys.org)—A panel of experts on the Nuclear Science Advisory Committee (NSAC) has decided to recommend closing the Relativistic Heavy Ion Collider (RHIC) in New York. The move comes after budget cuts for physics research via the Department of Energy, (DOE) in the United States, has led to making hard decisions regarding which facilities to continue to fund, and which to cut. As of 2007, the DOE was responsible for funding three major nuclear research facilities with a budget standing at $547 million.
