Life - Adult stem cells curing blindness
Adult stem cells are going from strength to strength. This latest case has cured blindness in 40 people.
I have always thought that if we didn't bother with embryonic stem cells (ESC) and instead focused on Adult stem cells that we would have a competitive edge. Scientifically, cloning has lots of problems (and ESC involved cloning), so any procedure that does not clone will be superior due to lack of complications.
Morally, ESC should also be avoided, but it is comforting to see that science and morality are on the same side here (of course, many scientists however are not)
