No magic wand required: Scientists propose way to turn any cell into any other cell type

In fairy tales, all it takes to transform a frog into a prince or a mouse into a horse is the wave of a magic wand. But in the real world, transforming one living thing into another isn't so easy. A new paper grounded in both math and biology lays out a way to do it with individual cells. If it works, it could have applications from regenerating diseased or lost tissue to fighting cancer.
