Interested my self, I'll tell you what I know
Evidently Biokinesis is the manipulation of life, or the living. I've not yet run across any in depth websites or sources as well, but the theoretical use is that one could use Biokinesis to "reprogram" some of the bodies' cells. one could change their eye color, ect.
Of course this is all theoretical, and i have yet to find truth in any of it, and of course, if you did it wrong, or reprogrammed the cells wrong, you could seriously screw up your body and potentially kill yourself.
