Ethically Sound Stem Cells

Scientists are working to make stem cells without destroying embryos, which would be awesome.

This interested me:

Fertility doctors have known for years that early embryos seem unfazed by the removal of any one of their eight virtually identical cells, called blastomeres. In fact, it is common today to remove a single, representative blastomere from a laboratory-conceived embryo and test that cell for disease genes before deciding whether to transfer that embryo into a woman’s womb.

To my head, this seems to be a common practice that (among many others, I’m sure) would have to be considered ghoulish by those who believe such embryos are fully human – as the President seems to.
