States vie for stem-cell scientists

Far from resolving an epic moral quandary, last year’s groundbreaking discovery that ordinary skin cells eventually could replace the use of human embryos in stem-cell research actually stoked the fiery debate over the cutting-edge science. 

Religious opponents hailed the skin-cell breakthrough as proof that research involving the destruction of embryos is unnecessary and must end. Scientists countered that studies on stem cells harvested from human embryos must continue for at least several more years while the new technique is perfected. And the battle went on.
