Quantum Researchers Able to Stop and Restart Light


Wednesday, 27 June 2012

‘In two independent experiments that defy the notions of Einstein, researchers have been able to stop, then restart a beam of light.

Ordinarily, light travels at the speed of 186,282 miles per second, but the research team of Lene Hau, a professor of physics at Harvard, who in 1999 was able to slow light down to 38 miles per hour, has been able to trap light in a cloud of sodium atoms super-cooled to near ‘absolute zero.’’

The unidentified object at the Bottom of the Baltic Sea Cuts off Electrical Equipment when Divers Get Within 200 Metres

‘The divers exploring a ‘UFO-shaped’ object at the bottom of the Baltic Sea say their equipment stops working when they approach within 200m.

Professional diver Stefan Hogerborn, part of the Ocean X team which is exploring the anomaly, said some of the team’s cameras and the team’s satellite phone would refuse to work when directly above the object, and would only work once they had sailed away.

He is quoted as saying: ‘Anything electric out there – and the satellite phone as well – stopped working when we were above the object.’

Scientists Find New Primitive Mineral in Meteorite


ScienceDaily (June 26, 2012) — In 1969, an exploding fireball tore through the sky over Mexico, scattering thousands of pieces of meteorite across the state of Chihuahua. More than 40 years later, the Allende meteorite is still serving the scientific community as a rich source of information about the early stages of our solar system’s evolution. Recently, scientists from the California Institute of Technology (Caltech) discovered a new mineral embedded in the space rock — one they believe to be among the oldest minerals formed in the solar system.

Dubbed panguite, the new titanium oxide is named after Pan Gu, the giant from ancient Chinese mythology who established the world by separating yin from yang to create the earth and the sky. The mineral and the mineral name have been approved by the International Mineralogical Association’s Commission on New Minerals, Nomenclature and Classification. A paper outlining the discovery and the properties of this new mineral will be published in the July issue of the journal American Mineralogist, and is available online now.

“Panguite is an especially exciting discovery since it is not only a new mineral, but also a material previously unknown to science,” says Chi Ma, a senior scientist and director of the Geological and Planetary Sciences division’s Analytical Facility at Caltech and corresponding author on the paper.

Gravitational Lensing: Astronomers Spot Rare Arc from Hefty Galaxy Cluster


ScienceDaily (June 26, 2012) — Seeing is believing, except when you don’t believe what you see. Astronomers using NASA’s Hubble Space Telescope have found a puzzling arc of light behind an extremely massive cluster of galaxies residing 10 billion light-years away. The galactic grouping, discovered by NASA’s Spitzer Space Telescope, was observed as it existed when the universe was roughly a quarter of its current age of 13.7 billion years. The giant arc is the stretched shape of a more distant galaxy whose light is distorted by the monster cluster’s powerful gravity, an effect called gravitational lensing. The trouble is, the arc shouldn’t exist.

“When I first saw it, I kept staring at it, thinking it would go away,” said study leader Anthony Gonzalez of the University of Florida in Gainesville, whose team includes researchers from NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “According to a statistical analysis, arcs should be extremely rare at that distance. At that early epoch, the expectation is that there are not enough galaxies behind the cluster bright enough to be seen, even if they were ‘lensed,’ or distorted by the cluster. The other problem is that galaxy clusters become less massive the further back in time you go. So it’s more difficult to find a cluster with enough mass to be a good lens for gravitationally bending the light from a distant galaxy.”

Now Facebook Tries to ‘Hijack’ Users’ Email Addresses by Forcing Them to Submit to Own Service


Wednesday, 27 June 2012

‘Facebook is trying to force its 900million users to switch to its own email service.

It is removing the personal email address displayed on an individual user’s profile pages and replacing it with a @facebook.com address – even if the member never uses it.

The social networking site’s email service was launched two years ago but has failed to take off, possibly because most people do not like having multiple mail accounts.’

Geoflow: Space Station Experiments Shed Light On Conditions Deep Inside Earth


ScienceDaily (June 25, 2012) — ESA astronaut André Kuipers is running experiments on the International Space Station that are shedding light on conditions deep inside Earth. Orbiting some 400 km above us, Geoflow is offering insights into the inner workings of our planet.

Descending 3000 km under our feet, Earth’s mantle is a semi-solid fluid under our thin outer crust. The highly viscous layers vary with temperature, pressure and depth.

Understanding how the mantle flows is a major interest for geophysics because it could help to explain earthquakes or volcanic eruptions. Computers can model it, but how can scientists be sure they are correct?

By Twisting Light Signals into a Vortex, Researchers Create Fastest Wireless Connection Ever


By Clay Dillow 06.25.2012

By twisting radio waves into a threaded vortex, an international team of researchers has beamed data through the air at 2.5 terabits per second, creating what has to be the fastest wireless network ever created. Moreover, the technique used to create this effect has no real theoretical ceiling, ExtremeTech reports.
