ProtoLife, LHC and the End of the World Mad Scientist Party

What an interesting week this. First Wired reports that scientists are on the verge of creating a new life form synthetically. There have been earlier attempts but they used some existing cell as the base machinery. This seems to be completely synthetic.
Then the big one. LHC goes live today. Not the big bang that its expected to perform but the first scaled down run to test systems happen today (might have actually happened - slow net here so not in a mood to open too many sites). The world's biggest physics experiment starts today. LHC (thats a machine that 'accelerates' particles to near the speed to light) in CERN (a lab in Switzerland build by European countries. it was one of their scientist who built the "www" you see in internet to easily share documents) turns on today.
LHC will if all goes well in the full trial today, swing a beam of protons in an underground 27 mile long circular tunnel cooled by 2000 superconducting magnets and another in the opposite direction. If that goes well, they will attempt to do it many times eventually reaching very very high speeds and then collide the two protons. What will result is interesting. It will be like a billionth of a second after big bang (theory that says universe was created in a sudden instantaneous explosion creating mass and energy). Then they'll check for many things among which is a particle called colloquially the "God Particle" or Higgs Boson, something that is postulated but not proven. It is what is supposed to give a mass to every other things.
Apart from the sheer engineering there is also a lot of controversy on the experiment, one of which is that the collision may create a microscopic black hole that may eat up the world. Apparently many such microscopic black holes are produced also in upper atmosphere due to collisions with solar radiation and our atmosphere but they "evaporate" since they are so small they can just go through everything without actually bumping into anything (most of an atom is just empty space) so the world in majority opinion is safe. Another view is that the microscopic black holes created by cosmic radiations are created at near speed of light and so have the escape velocity while those created in LHC may be too slow to escape Earth's gravitational pull and may stuck around like bad guests.
Time to call for a End-Of-The-World-Mad-Scientist-Party?
