Submission + - USC Lab Creates 3-D Holographic Displays (wired.com)

Submitted by ZonkerWilliam
ZonkerWilliam writes: USC has developed a novel 3D holographic display that not only does video but at a low cost as well.



The process is not simple but can be defined through a few key concepts: Spinning mirrors, high-speed DLP Projections, and very precise math that figures out the correct axial perspective needed for a 360-degree image (even taking into account a viewer's positioning.)

Submission + - Nerve-tapping neckband allows 'telepathic' chat (newscientist.com)

Submitted by ZonkerWilliam
ZonkerWilliam writes: Newscientist has an interesting article on tapping the nerve impulses going from the brain to the vocal chords, allowing for 'Voiceless' phone calls, as seen in the video. As quoted,

With careful training a person can send nerve signals to their vocal cords without making a sound. These signals are picked up by the neckband and relayed wirelessly to a computer that converts them into words spoken by a computerised voice.
It's not quite telepathy, but it's pretty close.

Submission + - More Spacecraft Velocity Anomalies (aip.org)

Submitted by ZonkerWilliam
ZonkerWilliam writes: The American Institute of Physics Bulletin has an excerpt of a study on recent spacecraft, such as NEAR, appear to have an anonymously acceleration much like Pioneer 10 had shown ten years ago. As quoted from the article,

A new look at the trajectories for various spacecraft as they fly past the Earth finds in each case a tiny amount of surplus velocity. For craft that pursue a path mostly symmetrical with respect to the equator, the effect is minimal. For craft that pursue a more unsymmetrical path, the effect is larger

Submission + - New accelerator technique doubles particle energy

Submitted by ZonkerWilliam
ZonkerWilliam writes: Plasma wake particle accelerators are making suprisingly quick advances. It was a just a little while ago we had Gev acceleration in 3cm; http://science.slashdot.org/article.pl?sid=06/10/0 4/0057225. Here they are capable of doubling the speed of electrons, in one meter. See the article for more information; http://www.physorg.com/news90682193.html

Submission + - Ocean Planets on the Brink of Detection

Submitted by ZonkerWilliam
ZonkerWilliam writes: Seems, at least theoretically, that there may be water planets, and that we may be close to detecting them. http://www.physorg.com/news89627725.html Excerpt from the article; "Imagine a world with no land at all, merely the impenetrable depths of a seething ocean. Models of planet formation predict the existence of such worlds, even though our own solar system has none. Indeed, their formation should actually be rather common — and new satellites may soon detect them around other stars."

Submission + - GeV Acceleration in Only 3 Centimeters

Submitted by
ZonkerWilliam
ZonkerWilliam writes: "Here is a very interesting article, for the scientific community at least, on the advancement of wake field particle accelerators. Being able to accelerate electrons to 1 Gev in the space of 3 cm just calls for portable devices that can be used anywhere, think of portable cancer therapies, if they can do the same for positrons, portable PET scans, possible use in compact fusion devices, capturing the dearly departed, etc. The uses are mind boggling.

http://www.aip.org/pnu/2006/split/795-2.html

Excerpt from article:

"Now the effort to impart more acceleration to particles over a short haul has taken a notable step forward. Physicists at the Lawrence Berkeley National Laboratory and the University of Oxford have accelerated electrons up to an energy of 1 GeV in a space of only 3 centimeters.""
