IAABiologist but not the stem cell kind. Point of clarification.

The line between cancer, stem and normal (non-proliferating or terminally differentiated) cells is *very* fuzzy.

For instance, if you take a cell from a normal developing placenta (in an experimental animal) and place it in the kidney, it turns into a tumor that is identical to an already known type of kidney cancer.

In short, should we thoroughly test stem cell therapies using full review and the best medical science? Hells YES!

(Don't make me use a car analogy to demonstrate my point.)

Little comment. There are abundant anaerobic bacteria in your mouth already. Many, many kinds. HP is invariably deadly to them. The issue here is concentration. No the bacteria in your mouth will never, ever develop immunity to the 2.5% H202 you get at the drug store. This is an insanely high concentration in biological terms. Compare a dental x-ray to Hiroshima, for instance.

New Scientist is also a good source for inaccurate information in the life sciences, too. IF you are in the market for misrepresented results and wild speculation about the implications of a biological finding, you can count on New Scientist to deliver. Bleh.
