AlQa'dah 22, 1433, Oct 8, 2012, SPA - The 2012 Nobel laureates in medicine, John B Gurdon (Britain) and Shinya Yamanaka (Japan), were Monday lauded for having "revolutionised" the understanding of how cells and organisms developed, according to DPA. "The Nobel Prize recognizes two scientists who discovered that mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body," the Nobel Assembly of the Karolinska Institute said in Stockholm. "Their findings have revolutionised our understanding of how cells and organisms develop."
