Two researches, John Gurdon from the UK and Shinya Yamanaka from Japan, who pioneered the production of stem cells used for treatments out of adult cells have won the Nobel Prize (BBC.com). Yamanaka was motivated by ethical concerns over embryonic stem cell research. He was once quoted as saying, “When I saw the embryo, I suddenly realized there was such a small difference between it and my daughters, I thought, we can’t keep destroying embryos for our research. There must be another way.” (“Induced Pluripotent Stem Cells: The Ethical Embryonic Alternative.” LifeNews.com)
