COULD the structure of space and time be sketched out inside a cousin of plain old pencil lead? The atomic grid of graphene may mimic a lattice underlying reality, two physicists have claimed, an idea that could explain the curious spin of the electron. Graphene is an atom-thick layer of carbon in a hexagonal formation. Depending on its position in this grid, an electron can adopt either of two quantum states - a property called pseudospin which is mathematically akin to the intrinsic spin of an electron. Most physicists do not think it is true spin, but Chris Regan at the University of California, Los Angeles, disagrees. He cites work with carbon nanotubes (rolled up sheets of graphene) in the late 1990s, in which electrons were found to be reluctant to bounce back off these obstacles. Regan and his colleague Matthew Mecklenburg say this can be explained if a tricky change in spin is required to reverse direction. Their quantum model of graphene backs that up. The spin arises from the way electrons hop between atoms in graphene's lattice, says Regan. So how about the electron's intrinsic spin? It cannot be a rotation in the ordinary sense, as electrons are point particles with no radius and no innards. Instead, like pseudospin, it might come from a lattice pattern in space-time itself, says Regan. This echoes some attempts to unify quantum mechanics with gravity in which space-time is built out of tiny pieces or fundamental networks (Physical Review Letters, vol 106, p 116803). Sergei Sharapov of the National Academy of Sciences of Ukraine in Kiev says that the work provides an interesting angle on how electrons and other particles acquire spin, but he is doubtful how far the analogy can be pushed. Regan admits that moving from the flatland world of graphene to higher-dimensional space is tricky. "It will be interesting to see if there are other lattices that give emergent spin," he says.

An analysis of the changes in the spin state is done with the help of absorption spectra is known as the electron spin resonance. If you are wondering what an electronic spin resonance means, then this article will explain you about it in detail.

Various polymers were tested for electron spin resonance (ESR) done at (SAIF) - IIT- Bombay to see the impact of The Trivedi Effect.

"Researchers at Ohio State University have demonstrated the first plastic computer memory device that utilizes the spin of electrons to read and write data. An alternative to traditional microelectronics, the "spintronics" device could store more data in less space, process data faster, and consume less power."

Lipase enzymes used in leather industry has achieved good results in degreasing of crepe, fur, leather, gelatin, and the like. Candida lipolytica lipase can reduce the oil content of the raw material of the spinning material from 10% to 0.5%, to meet the spinning requirements, and does not affect the fiber strength.

"Dieter Klemm forscht in zwei Spin-offs der Uni Jena, der "Polymet Jena Association" und der "Jenpolymer Materials", an medizinischen Anwendungen der Nanocellulose. Dabei nutzt er aus, dass sich die Fasernetze schon bei der Synthese in die gewünschte Form etwa als Vlies, Film oder Hohlkörper bringen lassen. Wenn er die Bakterien etwa auf einem Zylinder wachsen lässt, verbinden sich die von ihnen produzierten Fasern zu einer dichten Hülle. Entfernt man die Form, bleibt ein Röhrchen aus Nanocellulose übrig, das sich direkt als Implantat für Blutgefäße einsetzen lässt. Solche Implantate testet Klemm bereits an Tieren"

"I am going to try and experiment within an experiment today. I cloned a couple genes from yeast and have been spending months now trying to get them into several vectors for my combinatorial overexpression project. However, as it goes with wet messy biology, this seemingly simple process has been fighting me tooth and nail. I have retrieved one good clone out of 56 minipreps (plasmid construct isolation) and tried several ligations. So I have tripled down this week. In the picture here, I have 32 tubes, each with 5 individual E. coli colonies. That is a grand total of 160 isolates. 1.5 mL of cells have been transferred from overnight cultures and I am about to spin, lyse, and retrieve."

To try to illustrate the concept, the Max Planck Institute for Gravitational Physics made the accompanying movie of "Quantum Spin Dynamics in Loop Quantum Gravity." It depicts the quantum evolution of geometry in Loop Quantum Gravity

Peak Oil is the point at which petroleum production reaches its greatest rate just before going into perpetual decline. In "Peak Oil and a Changing Climate," a new video series from The Nation and On The Earth productions, radio host Thom Hartmann explains that the world will reach peak oil within the next year if it hasn't already. As a nation, the United States reached peak oil in 1974, after which it became a net oil importer. Bill McKibben, Noam Chomsky, Nicole Foss, Richard Heinberg and the other scientists, researchers and writers interviewed throughout "Peak Oil and a Changing Climate" describe the diminishing returns our world can expect as it deals with the consequences of peak oil even as it continues to pretend it doesn't exist. These experts predict substantially increased transportation costs, decreased industrial production, unemployment, hunger and social chaos as the supplies of the  fuels on which we rely dwindle and eventually disappear. Chomsky urges us to anticipate the official response to peak oil based on how corporations, news organizations and other institutions have responded to global warming: obfuscation, spin and denial. James Howard Kunstler says that we cannot survive peak oil unless we "come up with a consensus about reality that is consistent with the way things really are." This documentary series hopes to help build that consensus. Click here to watch the introductory video, and check back here for new videos each Wednesday.

ScienceDaily (June 4, 2011) - Do the principles of quantum mechanics apply to biological systems? Until now, says Prof. Ron Naaman of the Institute's Chemical Physics Department (Faculty of Chemistry), both biologists and physicists have considered quantum systems and biological molecules to be like apples and oranges. But research he conducted together with scientists in Germany, which appeared recently in Science, shows that a biological molecule -- DNA -- can discern between quantum states known as spin.

Entropy can decrease, according to a new proposal - but the process would destroy any evidence of its existence, and erase any memory an observer might have of it. It sounds like the plot to a weird sci-fi movie, but the idea has recently been suggested by theoretical physicist Lorenzo Maccone, currently a visiting scientist at MIT, in an attempt to solve a longstanding paradox in physics.

A turbine is a machine used to convert energy generated by moving liquid, gas or air into work. For example, the energy produced by fast flowing water is made to spin a rotating shaft by pushing on the angled blades set around a wheel mounted on the shaft, and this action produces the required work. ...
