Submission + - Hubble accuracy surpassed by earthbound telescope (arizona.edu)

randuev writes: High-speed adaptive optics system helped Large Binocular Telescope (on earth) to beat accuracy of Hubble Telescope (space) observations.

"A special sensor detects atmospheric distortions in real time and controls the mirror to adjust its position to compensate, effectively canceling out the blurring. The mirror can make adjustments every one-thousandth of a second, with accuracy to better than ten nanometers (a nanometer is one millionth the size of a millimeter)."

Now, that's what I call real-time. This nifty trick multiplied Strehl ratio (optical quality) of LBT by about 80 times to unprecedented Rayleigh limit. Hope we'll see more space around us in higher resolution on Google Sky.

Submission + - First Membrane Controlled by Light Developed

An anonymous reader writes: A new membrane developed at the University of Rochester's Laboratory for Laser Energetics blocks gas from flowing through it when one color of light is shined on its surface, and permits gas to flow through when another color of light is used. It is the first time that scientists have developed a membrane that can be controlled in this way by light.

Submission + - BlackBerry Services To Be Halted In UAE (bloomberg.com)

WrongSizeGlass writes: Bloomberg is reporting RIM’s BlackBerry Messenger, e-mail and Web browsing services will be suspended in the United Arab Emirates, the Middle East’s business hub, starting October 11th due to security concerns. RIM faces similar restrictions in India. The Telecommunications Regulatory Authority said in a statement on state-run Emirates News Agency. “In their current form, certain BlackBerry services allow users to act without any legal accountability, causing judicial, social and national security concerns for the U.A.E.,” it said. A senior Indian government official said, "Though RIM has been fully cooperating ever since the matter was taken up with it in 2008, reports of the company's move to set up a server in China forced us to look at it in a different way."
