You want to hear something really fascinating? >> Sure. >> There's a slime mold and this slime mold is very, very good at navigating through mazes and challenges. The Japanese are so clever at this. They designed a nutrient maze replicating Tokyo and the Japanese subway system. And they started it with Tokyo and they put oats, which is a nutritional source. They inoculated what is on this basically an agar map with all of the major cities, the nodes around Tokyo. And they then makes each of those nodes had a piece of oat on them, which is a source of nutrition. The main oat was where Tokyo was. They inoculated it and then they let the slime mold grow. At first it grew out randomly, exploratorily, you know, just like you would do do if you're a hunter or something. You're hunting on the landscape looking for things. And then after about 28 hours, it reorganized itself in the most efficient way possible and reorganized the Japanese subway system in a more efficient manner than it's designed today. Thus they said, not me, this is in demonstration of cellular intelligence. >> Wow.
