Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

Nearly every cell in the human body carries a copy of the full human genome. So how is it that the cells that detect light in the human eye are so different from those of, say, the beating heart or the spleen?
