Stop CISPA: Save the Internet from the US
Right now, the US Congress is sneaking in a new law that gives them big brother spy powers over the entire web — and they’re hoping the world won’t notice. We helped stop their Net attack last time, let’s do it again.
Over 100 Members of Congress are backing a bill (CISPA) that would give private companies and the US government the right to spy on any of us at any time for as long as they want without a warrant. This is the third time the US Congress has tried to attack our Internet freedom. But we helped beat SOPA, and PIPA — and now we can beat this new Big Brother law.
Our global outcry has played a leading role in protecting the Internet from governments eager to monitor and control what we do online. Let’s stand together once again — and beat this law for good. Sign the petition then forward to everyone who uses the Internet! [Click]

Quantum Tricks Drive Magnetic Switching Into the Fast Lane
Apr. 3, 2013 — Researchers at the U.S. Department of Energy’s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies. Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices.
The discovery, reported in the April 4 issue of Nature, potentially opens the door to terahertz (1012 hertz) and faster memory speeds.
Ames Laboratory physicist Jigang Wang and his team used short laser pulses to create ultra-fast changes in the magnetic structure, within quadrillionths of a second (femtosecond), from anti-ferromagnetic to ferromagnetic ordering in colossal magnetoresistive materials, which are promising for use in next-generation memory and logic devices. Scientists, led by Ilias E. Perakis, at the University of Crete developed the theory to explain the observation.
So, some scientists have turned their attention to colossal magnetoresistive (CMR) materials because they are highly responsive to the external magnetic fields used to write data into memory, but do not require heat to trigger magnetic switching.
“Colossal magnetoresistive materials are very appealing for use in technologies, but we still need to understand more about how they work,” said Wang. “And, in particular, we must understand what happens during the very short periods of time when heating is not significant and the laser pulses are still interacting with magnetic moments in CMR materials. That means we must describe the process and control magnetism using quantum mechanics. We called this ‘quantum femto-magnetism.’”
Wang’s team specializes in using ultra-fast spectroscopy, which Wang likens to high-speed strobe photography, because both use an external pump of energy to trigger a quick snapshot that can be then re-played afterwards. In ultra-fast laser spectroscopy, a short pulse of laser light is used to excite a material and trigger a measurement all on the order of femtoseconds.
