HTTP:: Fractional Quantum Hall Effect Demonstrated in Graphene
--------
Graphene, the one-atom-thick sheet of carbon atoms that was discovered in 2004 at the University of Manchester, is the most avidly researched material today in the field of condensed-matter physics. Because electrons flow in a very peculiar way through it, experts believe it may constitute the replacement of choice for silicon, the main semiconductor in computer chips today. Just recently, researchers have discovered a new peculiarity in the material, when they have demonstrated the fractional quantum Hall Effect in it, ScienceNow reports. The scientists essentially proved that, within graphene, electrons could team up in pairs, which then behaved as if they were particles with only a fraction of the original electrons' mass. The FQHE is an embellishment of an esoteric phenomenon known as the Hall Effect, which was first established in 1879. The discovery of the QHE won the Nobel Prize in physics in 1985. As a voltage is applied to a metal bar, electrons within it flow !
naturally from one end to the other. If a magnetic field is applied vertically to the bar, then the electrons will be subjected to a sideways shove, which will force them to conglomerate on one side of the bar. This means that a voltage is also developed along the width of the bar, and also that the sideways volta...

HTTP:: Only Fat Women Hate Skinny Models Karl Lagerfeld Says
--------
Karl Lagerfeld, while famous for his highly innovative and boundary-breaking creations, is also known for saying the most hurtful things in the most blatant manner. He’s made his views on fat people public in the past as well, so it’s probably no wonder that he’s getting serious heat again, now that he said only fat women could possibly hate the thin models he featured in his collection, as the Examiner can confirm. In the midst of the heated debate of whether size-0 models are “created†by the designers who put them on the catwalk and whether the fashion industry is responsible for completely separating fashion from the real world, Lagerfeld puts in his two cents as well. Fashion IS an illusion and an art, therefore it’s supposed to be cut off from reality. Similarly, only fat women who sit on their couches eating all day long could possibly see anything wrong with size-0 models. “No one wants to see curvy women. You’ve got fat mothers with their bags of!
chips sitting in front of the television and saying that thin models are ugly.†Lagerfeld said in a recent interview. His comment did not come out of the blue: it followed an announcement from the German-language Brigitte magazine saying it would include regular-sized women in its spreads an...

HTTP:: Artificial Implants Boost Prosthetic Control
--------
Experts from the University of Michigan (UM) have recently announced the development of a new type of brain implant that could have the ability to boost people's capacity of interacting with their prosthetic devices, leading to an increased quality of life. Robotic appendages could thus become a lot more controllable, and people would have the ability to move them around, twist them and bend them according to will. They basically work in the same ways as previous methods of collecting brain signals, only more effectively and a lot better, Technology Review reports. An electrically conductive polymer is the basis for the new implants, the UM team reports. The instruments are made up of tiny polymer cups, which are so small, that they fit neatly at the end of the severed nerve endings. Electrical signals â€" which continuously move down the nerves even if there is no limb for them to flow to â€" are then picked up through these small cups, and sent to a computer, which tran!
slates the current into a set of commands for the robotic limb. “This looks like it could be an elegant way to control a prosthetic with fine movement. Rather than having a big dumb piece of plastic strapped to the arm, you could actually have an integrated tool that feels like it's part of the body,†Massachusetts In...

A new version of the full-featured movie converter, player and editor for Mac OS X, ReelBean, is now available from JS8 Media. ReelBean is capable of playing almost any Mac-supported video and audio format, and supports the use of third-party plugins that make proprietary formats available. Last month, JS8 Media announced that, with the release of ReelBean 4.32, the Chapter panel could be resized. The company also reduced memory usage and added Snow Leopard support to the program. Version 4.4 of the software (the newest yet) adds the Save Frame button to the toolbar and includes minor bug fixes, according to the developer. Besides offering options to play around with various formats, ReelBean boasts video-editing features as well, and allows you to separate video from audio, split movies, or playback at a slower or faster rate. You have the ability to play your original DVD movies using the same features, and even stream videos that you can record and save to your Mac. Yo!

HTTP:: New Gene Therapy Corrects Parkinson 039 s
--------
In a new set of experiments conducted on monkeys, researchers have managed to determine a new type of gene therapy aimed at curing the Parkinson's disease. The treatment apparently does not result in the involuntary muscle movements that are a direct consequence of other forms of therapy against the ruthless condition. At this point, the new method is being tested on a small number of volunteers, all of which are showing considerable signs of improvement, Nature News reports. Existing therapies against the disease revolve around administering the chemical levodopa, or L-DOPA, which is the precursor of the neurotransmitter dopamine. In patients suffering from the condition, levels of this transmitter are dangerously low, and healthcare experts hope that, by making the patients take this substance, they will at least be able to halt the evolution of the disease, if not completely reverse it. However, these treatments are plagued by side-effects, experts admit. While most !
patients regain the motor functions shortly after they start using L-DOPA, a few years later, they begin to develop severe and debilitating, physical and psychological side-effects. This means that therapies using the neurotransmitter precursor should only be used when absolutely necessary, and not as the standard in treating Parkinson's. In...

“Twilight†star and promising thespian Kristen Stewart is often perceived in the media as both indifferent and interesting. Because she admittedly has serious issues with switching to “interview speak,†people say she’s aloof, cold and bored. On the contrary, she tells the latest issue of Allure magazine, she is actually a boring person, not half of what people make of her. As fans must know, Kristen doesn’t like to speak of herself unless she really has to. However, when she does, it’s mostly to refute rumors that circulate in the media and the blogosphere, such as the one that she’s a style icon in the making.

Autoimmune diseases are among the most dangerous kind in the world. They manifest themselves when the body's own immune system begins to attack the central nervous system (CNS), inflicting severe damage, and eventually leading to death. Multiple sclerosis is one good example. Although the barriers that exist between the CNS and other parts of the body seem to be extremely well constructed, a new video shows precisely how T cells, an important part of the immune system, go through these defenses, and start their attacks. In the new investigation, a team of scientists from the University Medical Center Institute for Multiple Sclerosis Research, in Gottingen, Germany, managed to track down the movements of the T cells inside a mouse model, and got a chance to look at how they passed through the barrier surrounding the CNS. The research was led by Alexander Flugel, who is also the director of the Institute, Nature News reports. “There's a question about how immune cells that!
