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

Submitted by tcd004
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)

Submitted by eldavojohn
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.
