In order to track the movements of the cells, his team attached tiny magnetic particles to them before they transplanted them, and also injected them with a dye.
He told us that magnetic north is moving at a speed of 50 kilometers - about 30 miles - every year. He said that scientists nowadays use satellites to track the changes.
