Science is happening all the time.

I spent my whole day in a basement and cut away from the world (listening to lectures that while very interesting gave me horrible headache after nine hours). I finally got back home and checked the internet to see what happened in the world in the meanwhile. And the first thing I saw was the information that Craig Venter did it. His research team created brand new, artificial life. They made a bacteria with completely artificial genome.. They synthesized the whole functioning genome that was able to take over a dead M. capricolum cell and revive it. It is over one million bases long. This was tricky as current technology can't build DNA strands that long. They can only make DNA strands up to 1000 base pairs and then that had to be assembled together. And it worked -  they got functioning, replicating cell. It is a replica of already existing genome of a different, but closely related to the host cell, bacteria -  M. mycoides. Next step - a made up one. This is dawn of the production of custom made artificial organisms made for certain functions like producing needed proteins that are cleaner then the ones made now as their own metabolism is minimal.  Not to mention the possibility of making such sf concepts like reviving mammoths a reality.

That is not the end. The next one would be big enough news any other day. The Fermilab scientists found out a new way why we are all made of matter. This was one of the main things puzzling physicists about the begging of the Universe. Matter and anti-matter were both created in the Big Band and then went promptly to annihilate each other. What we are made of is the matter that was left after that. In theory there should've been equal amounts of matter and anti-matter but our existence proves that somehow there was a little bit more matter. There seems to be a preference for matter over antimatter in the way a collision product known as a neutral B meson decays. The by-products are more often muons then anti-muons. By 1% which in this case is gigantic difference. Oh, and by the way this also not does not fit with the Standard Model so there is more going on then we know so far.
