ScentCone writes "Transgenic pigs (and other critters) are valuable research tools because of their utility in studying human diseases. Tracking changes in some developing tissues is going to be easier, say a Taiwanese team that has introduced fluorescent, green proteins into the breeding. Said one of the researchers: 'There are partially fluorescent green pigs elsewhere, but ours are the only ones in the world that are green from inside out. Even their hearts and internal organs are green.' Do you like green eggs and ham?"
