Thanks for your long post touching on the role of mitochondria. While this list doesn't presume to be a scientific forum, it certainly would benefit from more authoritative input like yours. FYI, there was a brief item (non-scientific) on mitochondria in Science News; 5 Aug 95:84. Cheers, Joe J. R. Bruman (818) 789-3694 3527 Cody Road Sherman Oaks CA 91403
