(PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible "sparks" from the nothingness of a vacuum.

He predicts that quantum computers will be produced within 20 years. ----- The two towering achievements of modern physics are quantum theory and Einsteins general theory of relativity. Together, they explain virtually everything about the world in which we live. But almost a century after their advent, most people havent the slightest clue what either is about. Radio astronomer, award-winning writer and broadcaster Marcus Chown talks to fellow stargazer Fred Watson about his book Quantum Theory Cannot Hurt You. - Australian Broadcasting Corporation Marcus Chown is an award-winning writer and broadcaster. Formerly a radio astronomer at the California Institute of Technology, he is now cosmology consultant of the weekly science magazine New Scientist. The Magic Furnace, Marcus' second book, was chosen in Japan as one of the Books of the Year by Asahi Shimbun. In the UK, the Daily Mail called it "a dizzy page-turner with all the narrative devices you'd expect to find in Harry Potter". His latest book is called Quantum Theory Cannot Hurt You.

64% of college students in a global survey said that if forced to choose, they would opt for having an internet connection rather than a car. 40% said the internet is more important to them than dating, going out with friends, or listening to music. The Cisco Connected World Technology Report draws on surveys of some 1,400 students in 14 countries.Source: Is the Internet a Fundamental Human Necessity?

Imagine, Michael Chorost proposes, that four police officers on a drug raid are connected mentally in a way that allows them to sense what their colleagues are seeing and feeling. Tony Vittorio, the captain, is in the center room of the three-room drug den. He can sense that his partner Wilson, in the room on his left, is not feeling danger or arousal and thus has encountered no one. But suddenly Vittorio feels a distant thump on his chest. Sarsen, in the room on the right, has been hit with something, possibly a bullet fired from a gun with a silencer. Vittorio glimpses a flickering image of a metallic barrel pointed at Sarsen, who is projecting overwhelming shock and alarm. By deducing how far Sarsen might have gone into the room and where the gunman is likely to be standing, Vittorio fires shots into the wall that will, at the very least, distract the gunman and allow Sarsen to shoot back. Sarsen is saved; the gunman is dead. That scene, from his new book, "World Wide Mind," is an example of what Mr. Chorost sees as "the coming integration of humanity, machines, and the Internet." The prediction is conceptually feasible, he tells us, something that technology does not yet permit but that breaks no known physical laws.

(PhysOrg.com) -- An international team has removed a major obstacle to engineer quantum systems that will play a key role in the computers, communication networks, and even biomedical devices of the future.

Nissan collaborates with Swiss scientists to develop interface between man and machine, saying it will help road safety

And now, as CNC milling machines and stereolithography (three dimensional printing) devices fall in price to the point of being not out of reach for a hobbyist's workshop, home manufacture of scary "assault weapons" will soon be a few mouse clicks away.

A unique optical multitouch sensing technology using infrared sensors has been developed by researchers at the Interface Ecology Lab at Texas A&M University. ZeroTouch allows users to literally draw pictures in midair. It provides zero-force, zero-thickness, high-frame-rate, high-resolution, transparent multitouch sensing. ZeroTouch's new forms of free-air interaction are more precise than the Microsoft Kinect, the researchers said. ZeroTouch was demonstrated at the recent ACM Conference on Human Factors in Computing Systems in Vancouver, B.C.

A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the engineers who discovered it and proved that it works. The process, called 'photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

Scientists have developed a new type of holographic telepresence that allows the projection of a three-dimensional, moving image without the need for special eyewear such as 3-D glasses or other auxiliary devices. The technology is likely to take applications ranging from telemedicine, advertising, 

A new discovery could revolutionize display technology with e-paper that's fast enough for video yet cheap enough to be disposable.

The important debate on global warming under UN auspices provides but a partial picture of climate change; in addition to the devastating impacts of greenhouse gas emissions on the ozone layer, the World's climate can now be modified as part of a new generation of sophisticated "non-lethal weapons." Both the Americans and the Russians have developed capabilities to manipulate the World's climate. In the US, the technology is being perfected under the High-frequency Active Aural Research Program (HAARP) as part of the ("Star Wars") Strategic Defence Initiative (SDI). Recent scientific evidence suggests that HAARP is fully operational and has the ability of potentially triggering floods, droughts, hurricanes and earthquakes.

ScienceDaily (June 9, 2011) - Scientists have just reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail. This innovation, described in two papers in the Optical Society's (OSA) open access journal Biomedical Optics Express, will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention and more effective treatments.

Multiple Discovery is a very thorough study of independent simultaneous discovery in the history of science and technology. It seems that there is almost no instance of a great discovery or invention that was not discovered independently and simultaneously. In addition to a careful historical study, Lamb and Easton present a theory to explain multiple discovery, which they call evolutionary realism.

ScienceDaily (Apr. 4, 2011) - Scientists at the Vienna University of Technology (TU Vienna) have developed a method to steer waves on precisely defined trajectories, without any loss. This way, sound waves could be sent directly to a target, avoiding possible eavesdroppers.
