DARPA Developing Defensive Plasma Shield 318

Posted by Zonk from the now-we-just-need-blasters dept.
galactic_grub writes "According to an article at New Scientist, DARPA is developing a plasma shield that would allow troops to stun and disorientate enemies. The system will use a technology known as dynamic pulse detonation (DPD), which involves producing a ball of plasma with an intense laser pulse, and then a supersonic shockwave within the plasma using another pulse. The result is a gigantic flash and a loud bang in a the air. 'The company has also pitched a portable laser rifle, which would be lethal, to the US Army. It would weigh about fifteen kilograms, would have a range of more than a mile, and could have numerous advantages over existing rifles - better accuracy and the ability to hit a moving target at the speed of light.'"

Quantum Computer To Launch Next Week 224

Posted by kdawson from the spooky-computing-at-a-distance dept.
judgecorp writes "D-Wave Systems of British Columbia is all set to demonstrate a 16-qubit quantum computer. Simple devices have been built in the lab before, and this is still a prototype, but it is a commercial project that aims to get quantum devices into computer rooms, solving tricky problems such as financial optimization. Most quantum computers have to be isolated from the outside world (look at them and they stop working). This one is an 'adiabatic' quantum computer — which means (in theory, says D-Wave) that it can live with thermal noise and give results without having to be isolated. There's a description of it here — and pretty pictures too."

Congress to Debate Net Neutrality 227

Posted by CmdrTaco from the future-of-freedom dept.
evw writes "The NYTimes is reporting that legislation was introduced in the Senate on Tuesday in support of Net Neutrality. It is bipartisan legislation introduced by Olympia Snowe, R-Maine and Byron Dorgan, D-N. Dakota, however the article notes that Senator Snowe is one of the few Republicans that supports it. "Senior lawmakers, emboldened by the recent restrictions on AT&T and the change in control of Congress, have begun drafting legislation that would prevent high-speed Internet companies from charging content providers for priority access." This isn't the first attempt. Last year a similar amendment was blocked. However, conditions placed on AT&T in its merger with SBC have emboldened supporters of the legislation."
