Now Mitalipov is believed to have broken new ground both in the number of embryos experimented upon and by demonstrating that it is possible to safely and efficiently correct defective genes that cause inherited diseases.
Although none of the embryos were allowed to develop for more than a few days—and there was never any intention of implanting them into a womb—the experiments are a milestone on what may prove to be an inevitable journey toward the birth of the first genetically modified humans. […] Reached by Skype, Mitalipov declined to comment on the results, which he said are pending publication. But other scientists confirmed the editing of embryos using CRISPR. “So far as I know this will be the first study reported in the U.S.”
I cannot help, but for a few moments of fame, scientists take every risk, even “mass destruction and proliferation”.
It reminds me to the first gene therapy trial by French Anderson who was later stripped of tenure, fired from his faculty position and barred from the campus of his university.
