THE SCIENCE DIDN'T HAVE TO BE IMMORAL, THE LEFT JUST WANTED IT TO BE:
A Nobel winner's moral achievement (William Saletan, 10/11/2012, Pioneer Press)
Posted by Orrin Judd at October 13, 2012 8:07 PMShinya Yamanaka, a scientist at Kyoto University, loved stem-cell research. But he didn't want to destroy embryos. So he figured out a way around the problem. In a paper published five years ago in Cell, Yamanaka and six colleagues showed how "induced pluripotent stem cells" could be derived from adult cells and potentially substituted, in research and therapy, for embryonic stem cells. This week, that discovery earned him a Nobel Prize, shared with British scientist John Gurdon. But the prize announcement and much of the media coverage missed half the story. Yamanaka's venture wasn't just an experiment. It was a moral project.In the introduction to their Cell paper, Yamanaka and his colleagues outlined their reasons for seeking an alternative to conventional embryonic stem-cell research. "Ethical controversies" came first in their analysis. Technical reasons -- the difficulty of making patient-specific embryonic stem cells -- came second. After the paper's publication, Yamanaka told a personal story, related by The New York Times:Inspiration can appear in unexpected places. Dr. Shinya Yamanaka found it while looking through a microscope at a friend's fertility clinic. ... (H)e looked down the microscope at one of the human embryos stored at the clinic. The glimpse changed his scientific career. "When I saw the embryo, I suddenly realized there was such a small difference between it and my daughters," said Dr. Yamanaka. ... "I thought, we can't keep destroying embryos for our research. There must be another way."
