An article of interest in today's New York Times online:

Title: A New Clue to Explain Human Existence
Published: May 17, 2010
Author: Dennis Overbye

First Sentence: Physicists at the Fermi National Accelerator Laboratory are reporting that they have stumbled onto a new clue that could help unravel one of the biggest mysteries of cosmology: why the universe is composed of matter and not its evil-twin opposite, antimatter.

Thought this might be of some interest.

Here is the scientific paper referenced:

Looks like a 3.2 sigma detection, which is good, but I think it's definitely prudent to await validation from an independent check. I don't know much about high energy physics experiments, so I'm not qualified to judge any more than this about the paper. However, if true, it does seem like it should be quite enough CP violation to explain the matter/anti-matter asymmetry.
