Scientists in Japan have found a remarkably easy way to make cells that can grow into any tissue in the body. The method if it can be repeated in human tissue may lead to cheap and simple methods to make patient-matched stem cells that could repair damaged or diseased organs. In a series of elegant experiments researchers showed that cells plucked from mice could be turned into all-powerful master cells by immersing them in a mildly acidic solution for half an hour. Haruko Obokata at the Riken lab in Kobe Japan told the Guardian that her team was able to
