  •, the industry leader in CAD software, has announced it is partnering with biological printer manufacturer Organovo to create 3-D design software for designing and printing living tissue.It’s an area of interest to Autodesk, whose software runs the industrial design and architecture worlds, allowing them to expand further into new fields by helping researchers interface with new tools.Organovo’sbioplotter, one of the only machines that can shape living tissue, works like a standard desktop 3-D printers but uses living cells instead of ABS plastic. It creates tissue by printing a gel base material as a scaffold and then deposits cells which mature into living material that can be used in the process of developing new pharmaceuticals.
  • showing that tiny particles injected into a liquid crystal medium adhere to existing mathematical theorems, physicists at the University of Colorado Boulder have opened the door for the creation of a host of new materials with properties that do not exist in nature.The findings show that researchers can create a "recipe book" to build new materials of sorts using topology, a major mathematical field that describes the properties that do not change when an object is stretched, bent or otherwise “continuously deformed.” Published online Dec. 23 in the journal Nature, the study also is the first to experimentally show that some of the most important topological theorems hold up in the real material world, said CU-Boulder physics department Assistant Professor Ivan Smalyukh, a study senior author.The research could lead to upgrades in liquid crystal displays, like those used in laptops and television screens, to allow them to interact with light in new and different ways. One possibility is to create liquid crystal displays that are even more energy efficient, Smalyukh said, extending the battery life for the devices they’re attached to.
  • Well, the prototype won’t win any beauty contest.“Abstract—We present an input method which enables complex hands-free interaction through 3d handwriting recognition. Users can write text in the air as if they were usingan imaginary blackboard. Motion sensing is done wirelesslyby accelerometers and gyroscopes which are attached tothe back of the hand. “We propose a two-stage approachfor spotting and recognition of handwriting gestures. Thespotting stage uses a Support Vector Machine to identifydata segments which contain handwriting. The recognitionstage uses Hidden Markov Models (HMM) to generate thetext representation from the motion sensor data. Individualcharacters are modeled by HMMs and concatenated to wordmodels. Our system can continuously recognize arbitrarysentences, based on a freely definable vocabulary with over8000 words.”
  • Google’s upcoming Nexus 4 has Qi based charging built in.Apple has patents in this area also.
  • Researchers at the Atlas experiment finally updated the two-photon results. Observation and study of the Higgs boson candidate in the two photon decay channel with the ATLAS detector at the LHC.What they seem to have found is bizarre—so bizarre, in fact, that physicists assume something must be wrong with it. Instead of one clean peak in the data, they have found two an additional peak. There seems to be a Higgs boson with a mass of 123.5 GeV (gigaelectron volts, the measuring unit that particle physicists most often use for mass), and another Higgs boson at 126.6 GeV—a statistically significant difference of nearly 3 GeV. Apparently, the Atlas scientists have spent the past month trying to figure out if they could be making a mistake in the data analysis but they have found no mistake.
  • Peter Thiel has funded a project.. To generate electricity from a tornado. I am pretty sure they intend to produce their own vortexes rather than drawing power form Dorothy’s trip to Oz. company, AVEtec, plans proof-of-concept test to extract energy from a man-made, controlled tornadoSan Francisco - December 13, 2012 - The Thiel Foundation announced today three new grants awarded through Breakout Labs, its revolutionary revolving fund to promote innovation in science and technology. The most recent award takes the program into clean energy, with a bold new proposal to harness the power of atmospheric vortexes.AVEtec is the brainchild of Canadian engineer, Louis Michaud. His Atmospheric Vortex Engine (AVE) harnesses the physics of tornados to produce extremely cheap and clean energy. In his design, warm or humid air is introduced into a circular station, where it takes the form of a rising vortex, i.e. a controlled tornado. The temperature difference between this heated air and the atmosphere above it supports the vortex and drives multiple turbines. The vortex can be shut down at any time by turning off the source of warm air.Among its advantages over other sources of energy, AVE power generation neither produces carbon emissions nor needs energy storage. AVEtec projects that the cost of the energy it generates could be as low as 3 cents per kilowatt hour, making it one of the least expensive forms of energy production. An AVE power station could have a diameter of 100 meters and generate 200 megawatts of electrical power, the same order of magnitude as conventional coal power stations."The power in a tornado is undisputed," said Louis Michaud. "My work has established the principles by which we can control and exploit that power to provide clean energy on an unprecedented scale. With the funding from Breakout Labs, we are building a prototype in partnership with Lambton College to demonstrate the feasibility and the safety of the atmospheric vortex engine."
  • The vortex energy can be from an existing relative low intensity heat source like an existing power plant. Can increase overall energy produced by up to 25%.What is the net impact of an AVE on global warming? The vortex engine can help to alleviate global warming in several ways.1. The vortex engine increases the quantity of electrical energy produced by thermal power plants without increasing fuel consumption thereby permitting a reduction in the quantity of fuel required to meet human power needs.2. A vortex engine causes upward heat convection in the troposphere to take place slightly earlier than it would without vortex assistance thereby reducing the temperature at the bottom of the atmosphere. The vortex moves the heat higher up in the atmosphere permitting it to be radiated to space with less interference from greenhouse gases.3. A vortex engine whose heat source is either warm sea water or warm humid air produces power without requiring the combustion of fuel except for startup.
  • matter physics – the branch of physics responsible for discovering and describing most of these phases – has traditionally classified phases by the way their fundamental building blocks – usually atoms – are arranged. The key is something called symmetry.Using modern mathematics – specifically group cohomology theory and group super-cohomology theory – the researchers have constructed and classified the symmetry-protected phases in any number of dimensions and for any symmetries. Their new classification system will provide insight about these quantum phases of matter, which may in turn increase our ability to design states of matter for use in superconductors or quantum computers. Examples of symmetry-protected phases include some topological superconductors and topological insulators, which are of widespread immediate interest because they show promise for use in the coming first generation of quantum electronics.Classifying the phases of matter by describing their symmetries and where and how those symmetries break is known as the Landau paradigm. More than simply a way of arranging the phases of matter into a chart, Landau’s theory is a powerful tool which both guides scientists in discovering new phases of matter and helps them grapple with the behaviours of the known phases. Physicists were so pleased with Landau’s theory that for a long time they believed that all phases of matter could be described by symmetries. That’s why it was an eye-opening experience when they discovered a handful of phases that Landau couldn’t describe.New states contain a new kind of order: topological order. Topological order is a quantum mechanical phenomenon: it is not related to the symmetry of the ground state, but instead to the global properties of the ground state’s wave function. Therefore, it transcends the Landau paradigm, which is based on classical physics concepts.
  • Remember those nice interactive displays that Iron Man had? Well.. Enter the Z-Space display. being able to reach out and grab some of the 3-D objects you saw in the movie Avatar with your own hands. I recently tried a computer display that offers this sort of interactive experience—albeit on a smaller scale—and I think the technique could have many possible uses.The “Z Space” display, developed by Californian company Infinite Z, tracks a user’s eye and hand movements and adjusts the 3-D image that he or she sees in real-time. The resulting effect is stunning. Unlike the 3-D video seen in a movie theater or on a 3-D TV, you can move your head around an object—to look it from the side or from below, for instance—and the Z Space display will adapt and show you the correct perspective. You still need to wear a special pair of glasses in order to see the 3-D images generated by the display. But the glasses have an additional purpose. As well as showing different images for each eye (to create the illusion of depth perception), they have markers that reflect infrared light. This enables cameras embedded in the display to track the movement of your head (and thus your eyes) as you change your point of view. It’s easy to see how such technology could be very useful for designers, architects, and animators. But with luck, it could also find its way into a few consumer products. The effect would make for an awesome interactive gaming experience, or simply much more realistic and immersive 3-D video. (Of course, it would only work for one viewer.) But still, just imagine being able to physically propel 3-D angry birds at virtual pigs—way more satifying.Last month Infinite Z created a software development kit (SDK) for its ZSpace displays, which let other companies, as well as independent programmers, create software for it. The display normally costs but $3,995, but if you enroll in the company’s developer program, you can snag one for $1,500.
  • Magnonics – an extension of SpintronicsMagnonics is an exciting extension of spintronics, promising novel ways of computing and storing magnetic data. What determines a material’s magnetic state is how electron spins are arranged (not everyday spin, but quantized angular momentum). If most of the spins point in the same direction, the material is ferromagnetic, like a refrigerator magnet. If half the spins point one way and half the opposite, the material is antiferromagnetic, with no everyday magnetism.There are other kinds of magnetism. In materials where the electrons are “itinerant” – moving rapidly through the crystal lattice like a gas, so that their spins become strongly coupled to their motions – certain crystalline structures can cause the spins to precess collectively to the right or left in a helix, producing a state called helimagnetism.Helimagnetism most often occurs at low temperature; increasing the heat collectively excites the spin structure and eventually destroys the order, relaxing the magnetism. In quantum calculations, such collective excitations are treated like particles (“quasiparticles”); excitations that disrupt magnetism are called magnons, or spin waves. There is a well developed theory of helimagnons, yet little is known experimentally about how helimagnetism forms or relaxes on time scales of less than a trillionth of a second, the scale on which magnetic interactions actually occur.
  • MIT physicists grew this pure crystal of herbertsmithite in their laboratory. This sample, which took 10 months to grow, is 7 mm long (just over a quarter-inch) and weighs 0.2 grams. Image: Tianheng Han researchers have demonstrated experimentally the existence of a fundamentally new kind of magnetic behavior, adding to the two previously known states of magnetism.Ferromagnetism — the simple magnetism of a bar magnet or compass needle — has been known for centuries. In a second type of magnetism, antiferromagnetism, the magnetic fields of the ions within a metal or alloy cancel each other out. In both cases, the materials become magnetic only when cooled below a certain critical temperature. The Quantum Spin Liquid (QSL) is a solid crystal, but its magnetic state is described as liquid: Unlike the other two kinds of magnetism, the magnetic orientations of the individual particles within it fluctuate constantly, resembling the constant motion of molecules within a true liquid.
  • A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. Researchers say it could lead to an invisible knife for noninvasive surgery.Today focused sound waves blast apart kidney stones and prostate tumors. The tools work primarily by focusing sound waves tightly enough to generate heat."A major drawback of current strongly focused ultrasound technology is a bulky focal spot, which is on the order of several millimeters," Baac said. "A few centimeters is typical. Therefore, it can be difficult to treat tissue objects in a high-precision manner, for targeting delicate vasculature, thin tissue layer and cellular texture. We can enhance the focal accuracy 100-fold."The team was able to concentrate high-amplitude sound waves to a speck just 75 by 400 micrometers (a micrometer is one-thousandth of a millimeter). Their beam can blast and cut with pressure, rather than heat. This picture: With a new technique that uses tightly-focussed sound waves for micro-surgery, University of Michigan engineering researchers drilled a 150-micrometer hole in a confetti-sized artificial kidney stone.
