Physicists unveil a theory for a new kind of superconductivity ( -- In this 100th anniversary year of the discovery of superconductivity, physicists at the University of Massachusetts Amherst and Sweden’s Royal Institute of Technology have published a fully self-consistent theory of the new kind of superconducting behavior, Type 1.5, this month in the journal Physical Review B. In three recent papers, the authors report on their detailed investigations to show that a Type 1.5 superconducting state is indeed possible in a class of materials called multiband superconductors. For years, most physicists believed that superconductors must be either Type I or Type II. Physicists unveil a theory for a new kind of superconductivity

Holographic dark information energy Holographic dark information energy Holographic Dark Information Energy gets my vote for the best mix of arcane theoretical concepts expressed in the shortest number of words – and just to keep it interesting, it’s mostly about entropy. The second law of thermodynamics requires that the entropy of a closed system cannot decrease. So drop a chunk of ice in a hot bath and the second law requires that the ice melts and the bath water cools – moving the system from a state of thermal disequilibrium (low entropy) towards a state of thermal equilibrium (high entropy). In an isolated system (or an isolated bath) this process can only move in one direction and is irreversible. A similar idea exists within information theory. Landauer’s principle has it that any logically irreversible manipulation of information, such as erasing one bit of information, equates to an increase in entropy.

Human Physiology - Neurons & the Nervous System The human nervous system consists of billions of nerve cells (or neurons)plus supporting (neuroglial) cells. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). Nervous system The nucleus of a neuron is located in the cell body. Extending out from the cell body are processes called dendrites and axons. These processes vary in number & relative length but always serve to conduct impulses (with dendrites conducting impulses toward the cell body and axons conducting impulses away from the cell body).

Two independent groups of physicists have unveiled the first phonon "lasers" – devices that emit coherent sound waves in much the same ways as lasers emit coherent light waves. Sometimes called "sasers", one of the devices emits sound at about 400 GHz while the other operates in the megahertz range. Such very high frequency sound could be used to probe the interiors of tiny objects – and the ability to create laser-like beams of sound could lead to new imaging applications. Indeed, the differences between the two devices suggest that sasers could be made to operate over a wide range of frequencies. At the heart of any optical laser is a medium with an electronic transition that involves the emission of a photon. Hail the first sound ‘lasers’ Hail the first sound ‘lasers’
Life's asymmetry may come from space Processes taking place in outer space, and not on Earth, are likely to have led to the biological molecules found exclusively in either a left-handed or right-handed form. That is the conclusion drawn from recent experiments carried out at the SOLEIL synchrotron facility near Paris in which a number of simple molecules found in star-forming regions exposed to polarized radiation created amino acids with an imbalance of left- and right-handed molecules. So-called chiral molecules can exist in two forms, with one being the non-superimposable mirror-image of the other, even though both have the same chemical make-up. Although laboratory experiments will tend to produce equal quantities of the left- and right-handed versions of a given chiral molecule, many of the chiral molecules found in living organisms come in only one variety. For example, the amino acids that make up proteins only exist in the left-handed form, while the sugars found in DNA are exclusively right-handed. Life's asymmetry may come from space
Physicists craft Luneburg lens from silicon Physicists craft Luneburg lens from silicon Physicists in the UK have created a Luneburg lens – a lens able to focus light from all directions equally well – on a silicon chip. The device could one day find applications in on-chip Fourier optics, which are used by the telecoms industry to perform tasks from noise reduction to data compression. Most practical lenses have aberrations, which means that their ability to focus light deteriorates when the incident light is off-axis.
Physicists in the US claim to have broken the record for the brightness of light generated by “sonoluminescence”, the imploding of a bubble when it is blasted with sound waves. With a peak power of 100 W, the light is 100 times as bright as seen in previous sonoluminescence experiments, and may help scientists understand how the strange phenomenon works. Sonoluminesence was discovered in the first half of the 20th century but it was only in the 1990s that physicists began to investigate the phenomenon seriously. Although no-one is sure how it works, the basic idea is that sound waves are fed into a vessel containing one or more bubbles inside a liquid.

Published: December 12, 2004 his April, a fire-hydrant-size apparatus called a thermoacoustic freezer made its debut at a Ben & Jerry's in Manhattan. The event was a relatively quiet affair, which was no small achievement: inside the core of the steel cooling unit, which was attached to a standard ice-cream cabinet, a loudspeaker emitted a 195-decibel screech to keep quarts of ice cream cold. From the outside, you could hear only a soft hum. The New York Times > Magazine > Thermoacoustic Freezer, The
As of 2008, the United States Department of Energy (DOE) and other U.S. federal agencies have spent approximately 18 billion dollars on energy devices using the fusion reaction between deuterium and tritium (D-T Fusion, below left). In this reaction the hydrogen isotope, deuterium (with one “extra” neutron) collides with the hydrogen isotope, tritium (with two “extra” neutrons), to form an alpha particle (a helium nucleus) and a neutron. This is a nuclear reaction: between them, the new alpha and the neutron possess 17.6 MeV (million electron volts) of energy. In the Fusion Reaction Cross-Sections graph (above right), the red DT (deuterium-tritium) curve peaks at about 40 KeV (forty thousand electron volts). Fusion Reactors

Just over a year agoseveral media outlets reported that John Kanzius, an amateur inventor from Erie, Pa., had discovered a seemingly impossible phenomenon: a way to burn salt water by exposing it to radio waves. Videos of the experiment became YouTube sensations, though they garnered as many critical comments as favorable ones. Now that the initial fervor has waned, we checked in with Kanzius, a collaborator and some critics to see how the technique has progressed, or if it's just another example of Web-propelled junk science. Kanzius' concept is simple: expose salt water to 13.56 MHz radio waves and light a match. Hydrogen separates from the water mixture and burns for as long as it's exposed to the frequency. The inventor actually made this discovery by accident: He was looking for a cure for cancer. Burning Salt Water on YouTube, Inventor Waits for Prime Time
