Pioneering space station experiment keeps reactions in suspense
Professor Guigné, who gained his PhD at Bath and is now a Visiting Professor in the University's Department of Physics, explained: "Space-DRUMS uses beams of sound energy to position solids or liquids which are floating in zero-gravity.
"Space-DRUMS uses beams of sound energy that work like invisible fingers that gently push the sample into the centre of the container so that it doesn't touch the walls. Those 20 'fingers of sound' arranged within a dodecahedron configured reactor such that the positions of the samples can be adjusted accurately.
"This method of acoustic levitation means there is no chemical contamination from the container, which is vital for making ultra-pure materials such as temperature-resistant ceramics used in coatings for planes and engines."
The equipment was initially tested in a low-gravity environment created by the vertical climbing and nose-diving flight path of a KC135 aeroplane, nick-named the vomit comet, similar to that used to train astronauts. source
My comment: Even if this sounds somewhat odd, it's very simple. It's levitation caused by sound waves. I think there was a video on the site but I don't remember. In any case, the idea is that the chemicals in the container will be confined by the sounds waves, thus they won't touch the walls. This is so cool! And it kind of reminds me of books about Tibetan levitation. Sure, it's much harder to induce it without technology, but the brain and the body are quite capable to produce different sounds. It's fun in any case.
US police could get 'pain beam' weapons
- 10:11 24 December 2008 by David Hambling
The research arm of the US Department of Justice is working on two portable non-lethal weapons that inflict pain from a distance using beams of laser light or microwaves, with the intention of putting them into the hands of police to subdue suspects.
The two devices under development by the civilian National Institute of Justice both build on knowledge gained from the Pentagon's controversial Active Denial System (ADS) - first demonstrated in public last year, which uses a 2-metre beam of short microwaves to heat up the outer layer of a person's skin and cause pain.
Like the ADS, the new portable devices will also heat the skin, but will have beams only a few centimetres across. They are designed to elicit what the Pentagon calls a "repel response" - a strong urge to escape from the beam.
A spokesperson for the National Institute for Justice likens the effect of the new devices to that of "blunt trauma" weapons such as rubber bullets, "But unlike blunt trauma devices, the injury should not be present. This research is looking to reduce the injuries to suspects," they say.
Existing blunt trauma weapons can break ribs or even kill, making alternatives welcome. Yet ADS has recorded problems too - out of several thousand tests on human subjects there were two cases of second-degree burns.
The NIJ's laser weapon has been dubbed Personnel Halting and Stimulation Response - PHaSR - and resembles a bulky rifle. It was created in 2005 by a US air force agency to temporarily dazzle enemies, but the addition of a second, infrared laser makes it able to heat skin too.
The NIJ is testing the PHaSR in various scenarios, which may include prison situations as well as law enforcement.
Human rights groups say that equipping police with such weapons would add to the problems posed by existing "non-lethals" such as Tasers. Security expert Steve Wright at Leeds Metropolitan University describes the new weapons as "torture at the touch of a button". source
My comment: Check the source to see a pic of the weapon. It looks so much like something out of a sci fi movie. However, I agree with the human right groups, if the weapon isn't leaving any traces of its use, how you're supposed to prove that someone abused you with it. It's absolutely impossible. That's why, even if it's better than taser, it's still very dangerous to hand such devices to police.
Virtual sex is coming soonJanuary 12th, 2009
Virtual sex is coming. While nearby porn stars autographed action photos and flashed their assets for camera-clutching fans at the annual Adult Entertainment Expo, Brett Drysdale discretely demonstrated "the newest breakthrough in sex technology."
He slipped two fingers into a rocket-shaped RealTouch device "developed and tested by a former NASA engineer" contains belts, lubrication jets, heating elements and other gadgetry programmed to give men the feeling of sex.
One end of the canister-type devices sized to fit easily in one's lap is made of soft "Haptic" synthetic material akin to that used for nipples of baby bottles.
The faux-flesh wall is slotted to allow the insertion of a body part of a man's choosing.
RealTouch devices connect to computers with USB cables and synchronize with adult movies streamed online so the inner workings replicate what a fellow might be feeling were he to be the man in the film.
"You watch the action on a screen and a signal is sent to the box to simulate what is happening," Drysdale said.
The device works with video from an online RealTouch "theater" at a price of one dollar per minute. RealTouch is priced at 150 dollars and begins selling in the US in February.
RealTouch product manager Drysdale said Sunday that it will be available internationally by mid-year. source
My comment:Nice, huh! I love it :) Just imagine the texture. Mmm.
