To develop the ‘virtual’ embryo, Xiaojie Qiu, a geneticist at Stanford University in California, and his colleagues built a model named Spateo, which stitches together multiple types of data.

Now - the clever bit. The cells on the inside layer of this very early embryo can make all of the cell types needed in your body. They're called stem cells. The stem cells continue to divide by ...
