German scientists of Karlsruhe Institute of Technology have succeeded in encoding data at a rate of 26 terabits per second on a single laser beam, transmitting them over a distance of 50 km, and decoding them successfully. This is the largest data volume ever transported on a laser beam. The process developed by KIT allows to transmit the contents of 700 DVDs in one second only.

(PhysOrg.com) -- Japanese researchers, led by Masashi Kawasaki, have discovered that a previously known kind of double layered material created using electrostatic doping can be used as a superconductor.

High-temperature superconductivity can be looked at as a fight for survival at the atomic scale. In an effort to reach that point where electrons pair up and resistance is reduced to zero, superconductivity must compete with numerous, seemingly rival phases of matter.

The three Large Hadron Collider (LHC) experiments that study lead ion collisions all presented their latest results today at the annual Quark Matter conference, held this year in Annecy, France. The results are based on analysis of data collected during the last two weeks of the 2010 LHC run, when the LHC switched from protons to lead-ions

(PhysOrg.com) -- The ability to entangle particles is considered essential for a number of experiments and applications. While we have seen evidence for quantum entanglement, it is still difficult to detect unambiguously. Multiparticle quantum correlations are especially important for work with optical lattices, superconducting qubits and quantum information processing

(PhysOrg.com) -- Just when it began to appear that scientists had found a viable way around the problem of the blurring that occurs when using masks to create smaller and smaller silicon wafers for computer chips, a previous study on beam splitting optics showed that the new approach would not work, at least as it has thus far been proposed. A group of researchers explain why in a paper in New Journal of Physics.

Researchers at MIT have succeeded in making a fine thread that functions as a diode, a device at the heart of modern electronics. This feat made possible by a new approach to a type of fiber manufacturing known as fiber drawing could open up possibilities for fabricating a wide variety of electronic and photonic devices within composite fibers, using a variety of materials.

The ability to image single biological molecules in a living cell is something that has long eluded researchers; however, a novel technique, using the structure of diamond, may well be able to do this and potentially provide a tool for diagnosing, and eventually developing a treatment for, hard-to-cure diseases such as cancer.

Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee have for the first time successfully characterized the earliest structural formation of the disease type of the protein that causes Huntington's disease. The incurable, hereditary neurological disorder is always fatal and affects one in 10,000 Americans.

Gaining and maintaining a strong foothold in the European and global technology markets is high on the EU agenda. Helping meet this goal is the ELI ('Extreme light infrastructure') project, which clinched EUR 6 million under the Research Infrastructures budget line of the EU's Seventh Framework Programme (FP7) to build a laser of intensity sufficient to rip photons into electron-positron pairs.

(PhysOrg.com) -- In a paper published on arXiv, Cuban physicist Ernesto Althsuler and his team at the University of Havana, describe how they set out to reproduce a phenomenon they had observed while brewing the Argentinean drink mate, a type of tea. Althsuler noticed that after causing hot water to drop from one vessel down a very slight waterfall into another containing tea leaves, some of the leaf particulates managed to make their way back up the waterfall and into the hot water vessel.

(PhysOrg.com) -- It is very difficult to overestimate the importance of colloidal suspensions. Besides being an integral part of our everyday life (food, cosmetics, drugs), they also serve as an excellent model system for basic science.

A biomechanical experiment conducted at the University of Pennsylvania School of Engineering and Applied Science has answered a long-standing theoretical question: Will microorganisms swim faster or slower in elastic fluids? For a prevalent type of swimming, undulation, the answer is 'slower.'
