With Master Chief finishing the fight against the Covenant in Halo 3, one has to wonder what's next for the Xbox 360's biggest star. Speculate no more as he prepares to take on an enemy so dangerous, it kills over half a million people a year. It can't be killed with gunfire, and once it locks on, there's little anyone can do to stop it. The monster? Breast cancer.

On October 20, 2007, there will be a Halo 3 tournament over Xbox Live organized by Bungie Studios and Cavegirls. Dubbed Fight Like a Girl 2, the tournament is geared toward raising money to provide a mobile mammogram machine. The first Fight Like a Girl tournament was able to raise US$ 777, and the organizer was able to buy a mobile mammogram machine for women in Seattle, Washington

Anyone can join the tournament to duel with fellow players and help fight breast cancer. The entry fee will be US$ 10.00 and the tournament starts at exactly 11:00 AM Pacific, 12:00 PM Mountain, 1:00 PM Central, and 2:00 PM Eastern.

If you're interested, don't hesitate to sign up for it. If you're thinking about your 10 dollars, just think that breast cancer can strike anyone, even men. Its victims can be anyone's parents or siblings. The money you spend will go a long way, so go right into the battle and be on the side of the angels.

After an earlier analysis of gamma ray emission from the black hole located in the center of our galaxy, the Milky Way, scientists have come to conclude that the emissions may be the product of dark matter decaying. But other scientists believe the constantly moving magnetic fields around the black hole can become a giant particle accelerator. And when particles collide in extreme speeds, it produces gamma rays.

Gamma-ray observatories have detected energetic gamma rays in the tens of Tera-electron volts (TeV) streaming from the center of the Milky Way outward. David Ballantyne from the University of Arizona led the study investigating on the possible particle acceleration scenario.

Results helped scientists conclude that protons could reach energies of 1000 TeV as they travel outward from the black hole, constantly gaining more and more velocity. This number is 100 times higher than the energies protons will be able to reach in the Large Hadron Collider (to be the world's largest particle accelerator) under construction in Geneva, Switzerland.

Now how about that? Our galaxy's biggest vacuum doubles as a super weapon. Sure beats the ring world Master Chief blew up, eh?
