Professor X style

I have never been a big fan of all the details that go into science and figuring out how it all works but I always enjoy seeing what science and technology can do, whether its the creation of the invisible cloak from the Harry Potter movies or scar-less laser surgery, it blows my mind.  When I saw this video and read about this a couple of months ago, it was cool, but frightening.  Those poor damn rats! They always get fucked with.  The video shows how the brain waves of thought sent a signal to the rats mind to move its tail.  We have all watched X-Men and I love Professor X because of his unique ability but never in a million years did I think that people would ever figure out how to use telekinetic powers to control other people and now it appears this may not be that far off.  It always starts with the damn rats.  What I don't understand is why is anyone researching this in the first place, what would be the purpose?  Maybe to find ways to help people with disabilities but other than that, other than control, what would it be used for? Who pays for this research?  Once again my mind is blown by science.  And really, we should all thank Stan Lee for creating the X-Men for the creativity.  I cant imagine that he or anyone else could believe that someday, Professor X, might be any one of us.
