MIT Creates New Energy Source. This is some pretty exciting news.

MIT Creates New Energy Source

It seems that researchers at the Massachusetts Institute of Technology (MIT), one of the most prestigious science and engineering schools in the United States, has created a new energy source -- and it's clean and renewable. The odd thing is that the only way you can see this energy source is with a very powerful microscope, because it is created by using nanotechnology. For a few years now, we have been hearing about the possibilities offered by the new field of nanotechnology. Now it looks like the first usable breakthrough has been accomplished.

MIT has devised a process to generate electricity using nanotechnology. Heads Up, Hoverboarders: Here Comes Quantum Levitation. Few motifs of science fiction cinema have been more appealing to us than the subtle defiance of gravity offered by futuristic hovercraft.

Heads Up, Hoverboarders: Here Comes Quantum Levitation

So every once in a while we check in to see how humanity is progressing on that front, and whether the promise of hoverboards will be delivered by 2015 as evidenced in Back to the Future Part 2. We’re not quite there yet, but we’re definitely getting off the ground, so to speak. One-Minute Physics archive. Sandrine Ceurstemont, editor, New Scientist TV What's part of the universe?

You may think of it as incorporating everything that exists - both on Earth and in space - but could it also include the unknown? In this One-Minute Physics episode, film-maker Henry Reich delves into the notion of the universe as described by physics, distinguishing between the whole universe and what's observable. He looks at the three components of the universe that we are sure of and whether mathematics could be included or not. Then there is the concept of parallel universes that could extend our understanding of space.

Antimatter Academy - Briefing Room. Antimatter belt around Earth discovered by Pamela craft. 7 August 2011Last updated at 10:54 The antiprotons lie sandwiched between the inner and outer Van Allen belts (in red) around the Earth A thin band of antimatter particles called antiprotons enveloping the Earth has been spotted for the first time.

The find, described in Astrophysical Journal Letters, confirms theoretical work that predicted the Earth's magnetic field could trap antimatter. The team says a small number of antiprotons lie between the Van Allen belts of trapped "normal" matter. Ebon Musings: Reflections Beneath the Milky Way. ORBIT: WORK COMPLETE. Kabbalah and String Theory. Ten Dimensions According to string theory, all of reality exists in (exactly) ten dimensions.

Kabbalah and String Theory

There are four revealed dimensions (the three dimensions of space together with the fourth dimension of time) and an additional six concealed (spatial) dimensions. Better lasers for optical communications. Long-distance, high speed communications depend on lasers.

Better lasers for optical communications

But when information is transmitted down fiber optic cables, it's critical that the signal be clear enough to be decoded at the other end. Two factors are important in this respect: the color of the light, otherwise known as the wavelength, and the orientation of the light wave, known as polarization. A team from EPFL and the Swiss Federal Laboratories for Materials Science and Technology (EMPA) has developed a technique that improves control over these two parameters. Rainbow-trapping scientist now strives to slow light waves even further. An electrical engineer at the University at Buffalo, who previously demonstrated experimentally the "rainbow trapping effect" -- a phenomenon that could boost optical data storage and communications -- is now working to capture all the colors of the rainbow.

In a paper published March 29 in the Proceedings of the National Academy of Sciences, Qiaoqiang Gan (pronounced "Chow-Chung" and "Gone"), PhD, an assistant professor of electrical engineering at the University at Buffalo's School of Engineering and Applied Sciences, and his colleagues at Lehigh University, where he was a graduate student, described how they slowed broadband light waves using a type of material called nanoplasmonic structures. Gan explains that the ultimate goal is to achieve a breakthrough in optical communications called multiplexed, multiwavelength communications, where optical data can potentially be tamed at different wavelengths, thus greatly increasing processing and transmission capacity.

Search for dark matter moves one step closer to detecting elusive particle. Dark matter, the mysterious substance that may account for nearly 25 percent of the universe, has so far evaded direct observation.

Search for dark matter moves one step closer to detecting elusive particle

But researchers from UCLA, Columbia University and other institutions participating in the international XENON collaboration say they are now closer than ever before. Their new results, announced April 14 at the Gran Sasso National Laboratory in Italy, where the XENON experiment is housed deep beneath a mountain 70 miles west of Rome, represent the highest-sensitivity search for dark matter yet, with background noise 100 times lower than competing efforts. Dark matter is widely thought to be a kind of massive elementary particle that interacts weakly with ordinary matter. Physicists refer to these particles as WIMPS, for weakly interacting massive particles.

Delicate quantum bits have been stored in single atoms, a feat that could make accessing memory in quantum computers more convenient, as well as improving the range of quantum communication.

Unlike classical bits, which can store only a 0 or 1, qubits can be in a superposition of the two states at once. Two or more can also be "entangled" and remain linked across great distances. Both properties vastly enhance the power of quantum computers compared with the classical variety, and make quantum cryptography possible, where two people can be sure a secret key they shared was not intercepted. Best-ever quantum measurement breaks Heisenberg limit - physics-math - 23 March 2011. PHYSICISTS have made the most accurate quantum measurement yet, breaking a theoretical limit named for Werner Heisenberg.

Best-ever quantum measurement breaks Heisenberg limit - physics-math - 23 March 2011

The most accurate quantum measurements possible are made using an interferometer, which exploits the wave nature of matter and light. In this method, two identical beams of particles are sent along different paths to a detector, with one interacting with an object of interest along the way. Quantum Dots Can Tag Individual Molecules With A Fluorescent Glow. A team of engineers at Ohio State University have packed a nanoparticle full of fluorescent blinking quantum dots. When the particle is attached to a single molecule, it functions as a gaudily glowing beacon. With their bright, continuous fluorescent glow that transitions between red, green and yellow, the nanoparticle is a better way to tag molecules, both in its function and in its good looks. Earlier attempts to tag molecules with bright quantum dots were hindered by the dots' on-and-off blinking, like trying to follow a blinking flashlight through a dark room.

The Ohio State engineers fixed the faulty flashlight. Led by assistant professor Jessica Winter and research scientist Gang Ruan, the team placed a group of quantum dots inside a slightly larger plastic nanoparticle. Warm Superconductors' Weird Behavior Could Indicate a New Phase of Matter. While studying the weird behavior of high-temperature superconductors, scientists may have found a new phase of matter, separate from solid, liquid, gas and plasma.

Electrons in a pre-superconducting state apparently form a strange, distinct order, lining up in a way that has never been seen before. Superconductors are 100-percent-efficient materials that waste no energy. In them, electrons break off into pairs, conducting electricity with no resistance. This usually requires operating at extremely cold temperatures, however, so superconductors are not quite practical for a wide range of uses. Scientists have been trying to make warm superconductors that can operate at room temperature, but warm superconductors experience a "pseudogap" while the electrons change their energy levels, preparing to team up and enter their superconducting states.


Engineered Metamaterials Could Recreate the Birth of Extra-Dimensional Universes in the Lab. Man-made metamaterials could theoretically bend light to create invisibility cloaks, or alter electromagnetic waves in ways nature never intended. Now, a researcher at the University of Maryland in College Park thinks they could do much more than that, becoming man-made analogies to various cosmological theories of how the Universe works and helping researchers explain certain aspects of those universes.

The theories Igor Smolyaninov has in mind are those that have to do with parallel universes or dimensions of space and time that we don't experience in this world. Big Bang Recreated in a Metamaterial, Offers Evidence That Time Travel is Impossible. Metamaterials can be used to create desktop black holes and simulate multiverses; now a physicist is using them to prove time travel can't happen. In a new paper, University of Maryland professor and metamaterial theorist Igor Smolyaninov says mapping light distribution in a metamaterial can serve as a model for the flow of time.

The model shows that the forward direction of time is unrelenting; you cannot curve back on time and go back to where you started. You just have to build a desktop Big Bang to prove it. Metamaterials can help with this, because they are engineered to exhibit properties that don't exist naturally. Holograms Powered By Quantum Effects Can Show True Color From Any Angle.

A new type of hologram harnesses a quantum effect and uses ordinary light to make 3-D still images. Future 3-D displays based on this technology would have no need for 3-D glasses or special screens. The technique is based on the behavior of free electrons on a metal surface, according to researchers at the RIKEN Institute in Japan. Researchers Succeed in Quantum Teleportation of Light Waves.
