Submission + - NASA strikes gold and water on the Moon (pbs.org)

tcd004 writes: The PBS NewsHour reports: there is water on the moon ... along with a long list of other compounds, including, mercury, gold and silver. That's according to a more detailed analysis of the cold lunar soil near the moon's South Pole. The results were released as six papers by a large team of scientists in the journal, Science Thursday. The data comes from the October 2009 mission, when NASA slammed a booster rocket traveling nearly 6,000 miles per hour into the moon and blasted out a hole. Trailing close behind it was a second spacecraft, rigged with a spectrometer to study the lunar plume released by the blast. The mission is called LCROSS, for Lunar Crater Observer and Sensing Satellite.

Submission + - Fermilab to Test Holographic Universe Theory (symmetrymagazine.org)

eldavojohn writes: Scientists at Fermilab have decided that it's high time they build a 'holometer' to test the smoothness of space-time. Theoretical physicists like Stephen Hawking have proposed that space-time is not smooth but it's been a lot of math and no actual data. By building two relatively small devices that act as "holographic interferometers" to measure the shaking or vibration in split beams of light traveling through a vacuum. If the team finds the shaking in their measurements and records them, the theory of a holographic universe will have some evidence of non-smoothness in space-time and perhaps a foothold in bringing light to the heavily debated theoretical physics.

Qutrits Bring Quantum Computers Closer 66

KentuckyFC writes "To do anything useful with quantum logic gates, you need dozens to hundreds of them, all joined together. And because of various errors and problems that creep in, that's more or less impossible with today's technology. Now an Australian group has built and tested logic gates that convert qubits into qutrits (three-level quantum states) before processing and then convert them back again. That makes them far more powerful. The group says that a quantum computer that might require 50 conventional quantum logic gates can now be built with just 9 of the new gates. What's more, the gates process photons using nothing more than standard linear optical components (abstract on the physics arxiv)."

Comment What's wrong with Vista? (Score 1) 488

I mean, besides the media's biased view, which in reality means nothing. I've run Vista since before the first release candidate. I've run unusual, and old hardware on it. I've run every game I've come across on it. Nothing ever asks me dumbass questions because I disabled UAC within the first 5 minutes. There are no security flaws that effect me (that actually matters) as "the usual user", oh noes, someone can see my porn or saved games! Hax! Who cares. Vista has crashed a whole 0 times since purchase. Vista has had no incompatibilites with anything. All of the drivers I've needed are all redily available and work perfect.. Will someone please tell me why Vista is "zomg Vista no way LOL". I expect the replys to go something like (1)"The UI is sooooooo demanding of GPU's", (2)"it iz unstabl3 n u r jus dum n stoopid lol15", and (3)"You obviously have no idea what you are talking about, be quiet." My pre-response to these: 1- Get a video card made within the past 3 years, it'll be fine, im doing it right now. 2- .. 3- You are apparently quite stubborn and opinionated, try it for yourself before reading "reviews". Microsoft Windows Vista, try it. It's not as bad as they say.
