Researchers push forward quantum computing research

San Francisco, May 21 (IANS) Stanford University electrical engineering Professor Jelena Vuckovic and colleagues at her laboratory are working on new materials that could become the basis for quantum computing. While silicon transistors in traditional computers push electricity through devices to create digital ones and zeros, quantum computers work by isolating spinning electrons inside...

Hawking's prediction on black hole observed in lab

Jerusalem, Aug 17 (IANS) Providing strongest evidence to the prediction made by physicist Stephen Hawking more than 30 years ago, scientists have created a virtual black hole in the lab and observed particles slipping out of its grasp. According to Hawking's prediction, black holes might not be bottomless pits and some information can escape black holes in the form of energy. If...

Novel way can make magnet spin like kittens

London, July 22 (IANS) Paving the way for the next-generation storage revolution, scientists have pioneered a novel effect arising from the relativistic physics of Albert Einstein that allows the fabrication of a new type of magnet that behaves like cats. Similar to a cat's ability to flip itself in the air by twisting different parts of her body in different directions and land on its f...

Scientists replicate folding human brain in 3D in lab

Washington, Feb 2 (IANS) Researchers at the Harvard University including an Indian-origin scientist have replicated a folding human brain in 3D, revealing for the first time a simple mechanical framework for how it folds. Understanding how the brain folds could help unlock its inner workings and unravel brain-related disorders as function often follows form. It shows that while m...

Novel phase of matter discovered

New York, Oct 27 (IANS) A team of physicists has discovered an unusual form of matter -- not a conventional metal, insulator, or magnet, for example, but something entirely different, a study says. This phase, characterised by an unusual ordering of electrons, offers possibilities for new electronic device functionalities, the study said. The discovery of this phase was completel...

Scientists solve quantum tunnelling mystery

Canberra, May 28 (IANS) An international team of scientists studying ultrafast physics has solved a mystery of quantum mechanics and found that quantum tunnelling is an instantaneous process, the Australian National University said on Thursday. The new theory could lead to faster and smaller electronic components for which quantum tunnelling is a significant factor. It will also lead to ...

Read research papers on Nature magazine for free

Washington, Dec 2 (IANS) All research papers from the scientific journal Nature will now be available free to read in a screen-view format that can be annotated but not copied, printed or downloaded, the journal's publisher Macmillan announced. ReadCube, a software platform similar to Apple's iTunes will be used to host and display read-only versions of the articles' PDFs. If the...

How GPS can find elusive dark matter

Washington, Nov 18 (IANS) The Global Positioning System (GPS) might be an effective tool in directly detecting and measuring dark matter - so far an elusive but ubiquitous form of matter responsible for the formation of galaxies. Andrei Derevianko from University of Nevada, Reno, and his colleague Maxim Pospelov from University of Victoria and the Perimeter Institute for Theoretical Phys...

In a first, Hawking radiation mimicked in lab settings

London, Oct 14 (IANS) Scientists have created a lab-scale imitation of a black hole that emits Hawking radiation - the particles predicted to escape black holes due to quantum mechanical effects. Such objects could one day help resolve the so-called 'black hole information paradox' - the question of whether information that falls into a black hole disappears forever, a report in the jour...

Improved method for isotope enrichment

New York, June 30 (IANS) Researchers have devised a new method for enriching a group of stable isotopes - among the world's most expensive chemical commodities - which are vital to medical imaging and nuclear power. Isotopes are among the most expensive commodities on earth, said Mark Raizen, a professor of physics at University of Texas at Austin in the US. One ounce of a stable iso...

Lasers recreate supernova explosion in lab!

London, June 2 (IANS) Scientists have now devised a method to study supernova explosions, a stellar explosion that briefly outshines an entire galaxy, by recreating them in the laboratory with the help of lasers. Researchers used laser beams 60,000 billion times more powerful than a laser pointer to recreate scaled supernova explosions in the laboratory as a way of investigating one of the ...

Device to make faster, cooler computers is here

Washington, April 7 - Here comes an optical device that may lead to new and more powerful computers that run faster and cooler. Researchers at Washington University in St Louis have developed an essential component of new computers that would run on light. We believe that our discovery would benefit many other fields involving electronics, acoustics, plasmonics and meta-materials, sa...

World's toughest material spurs next-gen chips

London, Oct 10 - Graphene, the world's thinnest and toughest material, could spur the development of next generation computer chips, besides revolutionising materials science. Its amazing properties open the way to bendable touch screen phones and computers, lighter aircraft, paper thin HD TV sets and lightning-quick net connections, and more. Andre Geim and Kostya Novoselov, both pr...

Why saliva forms beads when stretched?

Washington, June 12 - Some fluids, including saliva, form beads when they are stretched as they contain polymers which cause a line of beads to form just before the strand breaks. Study co-author Matteo Pasquali, Rice University professor in chemical and biomolecular engineering, said the study could lead to improvements as diverse as ink-jet printing, nanomaterial fiber spinning and drug d...

Transparent aluminium of science fiction is reality now

London, July 28 - Scientists have created a transparent form of aluminium by bombarding the metal with the world's most powerful soft X-ray laser. The discovery was made possible with the development of a new source of radiation that is 10 billion times brighter than any synchrotron in the world -. The FLASH laser, based in Hamburg, Germany, produces extremely brief pulses of s...

Scientists track movement of atoms in real time

Washington, May 18 - A new technique tracks movement of freely moving single neutral atoms in real time, that is more than 99.7 percent accurate and sensitive enough to discern the arrival of a single atom in less than a millionth of a second. The system, developed by researchers at the Joint Quantum Institute - in College Park and the Universidad de Concepcion in Chile, employs a novel...

Computers can become zillions of times faster

New York, Aug 21 - The fastest quantum computer bit or the qubit has been shown to be zillions of times faster than the conventional bit, potentially making computers that much faster. Scientists used lasers to create an initialised quantum state of this solid-state qubit at rates of about a gigahertz, or a billion times per second. A conventional bit can be a 0 or a 1 but a qub...
