Nobel Prize In Medicine

摘要

One trained in surgery then decided he was no good at it. The other was told by a teacher that the idea of his becoming a scientist was "ridiculous." But Japan's Dr. Shinya Yamanaka and Britain's John Gurdon persevered to share this year's Nobel Prize in Physiology or Medicine. Gurdon launched the field of stem-cell science in 1962 by proving that adult cells of a frog retain the genetic material needed to produce a new tadpole.
