+ - Cloak hides underwater objects from sonar-> 1

schwit1 (797399) writes "In one University of Illinois lab, invisibility is a matter of now you hear it, now you don't.

Led by mechanical science and engineering professor Nicholas Fang, Illinois researchers have demonstrated an acoustic cloak, a technology that renders underwater objects invisible to sonar and other ultrasound waves.

"We are not talking about science fiction. We are talking about controlling sound waves by bending and twisting them in a designer space," said Fang, who also is affiliated with the Beckman Institute for Advanced Science and Technology.

The researchers tested their cloak's ability to hide a steel cylinder. They submerged the cylinder in a tank with an ultrasound source on one side and a sensor array on the other, then placed the cylinder inside the cloak and watched it disappear from their sonar.

"The structure of what you're trying to hide doesn't matter," Fang said. "The effect is similar. After we placed the cloaked structure around the object we wanted to hide, the scattering or shadow effect was greatly reduced."

I'm sure the Navy will have kittens if this becomes practical. What's to protect the coast or carrier battle groups from enemy subs?"

Submitted by Neil
Neil (666) writes "Damon Sicore, Senior Director of Platform Engineering at Mozilla, has announced that the company is almost ready to ship Firefox 4. On its mailing list, Mozilla has revealed it has around 160 hard blockers to fix, before proceeding to Release Candidate stage. Both the RC and the final version would arrive in February, according to Sicore. Mozilla was originally planning on having Firefox 4 out by the end of last year, but it had to delay the release till 2011. Last month, Firefox 4 Beta 8 was released for Windows, Mac OS X, and Linux 32-bit/64-bit, with support for 57 languages. Mozilla's roadmap says it still wants to release a Beta 9, a Beta 10, and at least one Release Candidate build before the final version."
