Using Nanotechnology scientists has enabled injured hamsters to see again.In this BBC article, scientists injected hamsters with a solution of nanoparticles. Then the severed optical nerves regrew and then regained sight. I think this is so cool. The only problem is that it may mean the Borg are on the right track;). The article also mentioned one other interesting little fact. In order to simulate trama, the scientist severed the optic nerve. Has PETA heard about this? Have they issued a statement? Just curious;).
