Real good story of how a Japanese scientist changed the debate on stem cell research because he viewed the humanity of the embryo.
Money Quote:
"When I saw the embryo, I suddenly realized there was such a small difference between it and my daughters," said Yamanaka, 45, a father of two and now a professor at the Institute for Integrated Cell-Material Sciences at Kyoto University. "I thought, we can't keep destroying embryos for our research. There must be another way."
