"For the first time,"
reports the Washington Post, "an experimental treatment made from human embryonic stem cells has shown hints of helping someone, apparently restoring some vision for at least one and possibly two women losing their sight to incurable forms of progressive blindness."
And it only took how long? Adult stem cells have been helping people for years now.
One of the women refers to her restored vision as "a great gift." But that gift came at the cost of a life. I've never been partially blind and can't speak to what her experience has been like, but I would rather go blind than force an innocent human being to pay that kind of price for my eyesight.

Going back to Ben's question, I have to ask if twins have the same DNA, does that mean that only one of them is a "living" person? Obviously not.
Or, maybe, I don't understand the question. Am I missing something?
Which is why I have to answer your question about a clone as Gina did: no, I couldn't and wouldn't. If the clone has "life", then it is a separate being from me and deserves a chance to live her own life, not be sacrificed for mine.
Hmm.. so.. if embryos made via IVF each represent a "life" because of their unique DNA, what if you were able to make embryos with no DNA? or even better, with copies of your own DNA? Is it a separate "life" if it just has your DNA (i.e., it'd be your twin).. or would it okay to use this kind of embryo to grow you a new set of lungs?
Scientists have been able to take skin cells and turn them into embryo-like stem cells, and, in mice, they grew baby mice from these. So.. when this research gets to the point where it works in humans, would killing these embryo-like cells be murder, too?
All your cells have the same DNA - the difference between your liver cells nad heart cells is which parts of the DNA are turned on/off. Heck, that's the same as for a pair of identical twins. So I don't exactly follow the "a new unique life starts at conception" line of argument. Aren't identical twins unique?
