Chatterbox has added a few more snippets to his chart detailing what we know about President Bush's 64 stem-cell lines. This is journalism in the making!

As promised, he'll use the one-, two-, and three-star ratings that the Michelin Guide uses in its restaurant listings. It is, Chatterbox believes, the only ranking system universally recognized by M.D.s.
