British scientists have discovered "cognition" in a vegetative patient. This may encourage some at the "natural death" end of the pro-life spectrum. But I find it more to be a sign of our cultural denial of death than an affirmation of life.
There is an implied faith here that if a new drug manufacturer has paid for the research for FDA approval, then it is scientifically proven to be effective. As it turns out, this belief is by no means fully justified.
