'Restless Earth' may give advance notice of quakes
Signals that come from deep within the Earth eventually may give us a few days' warning before some large earthquakes, according to a scientist at NASA's Ames Research Center. The source of these signals lies deep in the Earth's crust, where forces squeeze rocks to the limit before they rupture catastrophically, shaking the ground with destructive force.

Astronomers pin down Dark Matter distribution
The Universe's mysterious invisible Dark Matter is distributed on large scales in exactly the same way the galaxies are, according to scientists analyzing data from the giant 2dF Galaxy Redshift Survey done with the 3.9-m Anglo-Australian Telescope in eastern Australia. The finding means the Universe is surprisingly simple.

Astronomers find a festive star that does the twist
Discovered by astronomers during Christmas observations in Australia, a star was found with a new phenomenon of twisting. The behavior demonstrates a slow change in the way the star spins on its axis. This twisting has been predicted by some theories of the way in which stars generate their magnetic fields, but until now it has never been observed directly.
