Evolution and cancer news

Every morning I check a couple of sites in order to get an overview of what is going on in the world. Today I found a couple of curious things:

On the more serious (and cancer related) front, A group of researchers at the University of Missouri-Columbia have found a way to find out the spread of skin cancer cells through the blood. The technique relies on the fact that the vibrations produced by a laser into a melanoma cell is different from that of other cells like red blood cells and plasma.

More information can be obtained here (for those with a subscription to the journal of optics letters).
A different kind of research has been noticed by the bigger media (BBC, Telegraph) and it seems to illustrate how not to use the theory of evolution. Researchers at the Darwin centre at the London School of Economics have seen the future and came back to tell us: Mankind will split into two separate species: the clever and beautiful and the dim-witted goblin-like. I have already heard people labelling these groups as the Macs and the PCs.
