I carefully collected all the E-books for the Doctorate trophy. In the Tai Yong Medical tower the book: 20: Icarus Landing System." "Better Than Nature?" was not the one I picked up. This is where you have to jump down a long vent shaft, there's a dead lab-coat guy there, and an e-book beside him. I went back to an earlier save to check, and the wrong book was there! The book has a different title, and this is the only one I am missing. I finished the game on hard difficulty and got all the other trophies. Has anyone else run into this problem?
