Glowing with Pride

I do realise that the title of the last entry seemed to suggest I was going to write about human genetic modification. I know of course that nobody is openly working on engineering a human but I assume that it would be technically possible to do so, for instance by inserting the bioluminescence gene so that a human would glow in the dark. When it happens you will know - when it is dark of course. In looking for some stuff on biolumninescence, I found this article about plankton revealing the whereabouts of submarines though Peter Herring of the Southampton Oceanography Center suggests it could be a joke. The bit about the U34 being sunk after it disturbed plankton is true though.
