...live birth during the entire course of treatment - up to six cycles of IVF. The study also incorporated data for all patients who sought treatment at the Massachusetts center, regardless of age or potential for pregnancy complications. In addition, the data accounted for success rates of IVF using frozen embryos; other analyses typically consider only "fresh" embryo...
...Cloning has generated controversy outside of ethics questions as well - or at least, outside of these particular ethics questions. In 2004, South Korean researcher Hwang Woo Suk shot to fame after claims that his team had successfully extracted potentially disease-curing stem cells from a cloned human embryo. However, mere months later, Hwang's reputation dissolved after a Seoul National University panel concluded that much of his research was "intentionally fabricated." Hwang was accused of doctoring pictures of his supposed patient-specific stem-cell lines and was forced to resign. Though the controversy stunned South Korea, the nation resumed...
Mango’s lab is currently studying how the gut forms in worms—useful because they are transparent and so scientists can study a complicated process, like organogenesis, by watching the organ form from beginning to end in a living embryo...
...moment, McCain seems determined to keep us confused about where he really stands. He has voted to fund research on leftover fertility-clinic embryos, but his website says he favors experiments that "do not involve the use of human embryos" at all. His party platform calls for an outright ban on all embryo research, public or private. Meanwhile, a McCain-Palin ad lauds the pair as the "original mavericks" for supporting "stem-cell research to help free families from the fear and devastation of illness."

...challenge to Republicans who promise to help parents of children "born with a birth defect." "Well, guess what, folks?" he said. "If you care about it, why don't you support stem-cell research?" Well, they do; just not all the forms that he supports. You can argue that embryo research should proceed anyway; you can argue about where federal funds should go, or whether embryos should be created specifically to experiment on them. But no one is served when politicians blur their positions or distort their opponents' or pretend the issue is simpler than...
