In the paper, a mold is grown on a plate with strategically placed food sources that resemble the Tokyo rail system. The mold then creates the most efficient pathing between the food nodes. It is really surprising that the biological map created from this highly resembles the actual engineered routes.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
