new source of stem cells discovered

This is potentially very important. It would appear that human menstrual blood could be an important source of the cells:

Japanese researchers have discovered a new source of stem cells: human menstrual blood. The ABC, Australia's public broadcast commission, reports the blood engendered 30 percent more stem cells than bone marrow, a more common source of the cells.

I would guess that should take a lot of heat off the ethical concerns around human stem cells being 'harvested' from foetuses. Thought religions that see blood, particularly menstrual blood as unclean might still have a problem with it. It'll be interesting what the Muslim reaction might be. I honestly don't know enough in this case to guess which way they might go on the matter.
