Please, please, please, go over to Squidalicious and read this review of Jenny McCarthy's book if you are even thinking about reading it. And check out the really nice bibliography at the bottom. Seriously, folks, get some real information. Pop biomed is not only inappropriate, it can be dangerous.
I mean, I love Ray Bradbury and Ursula LeGuinn, but I'm not about to base any physics articles on The Martian Chronicles or The Left Hand of Darkness.
Don't get caught in negativity and pop-culture abilism. Get real information from real scientists, doctors, and trained specialists. That minefield of people is quite enough to try to navigate without the likes of celebrities obscuring the way.
