Straight talk: Adult and embryonic stem cells and the future of research
...ne knew if one would turn out to be better, and as fate would have it, each has its niche, even today." Similarly, he says, pursuing research with both embryonic stem cells and adult stem cells is the most reasonable way to learn what scientists and doctors don't know about stem cells. "Stem cells from ...Whale populations are too low to resume commercial hunting, geneticists find

In their Science report, Roman and Palumbi analyzed DNA samples from 87 minke whales and concluded that the pre-whaling North Atlantic minke population was at least 265,000 roughl...Nitric oxide may change basic understanding of cellular machinery
