Physarum Polycephalum may look like a fungus, but it’s actually a single-celled life-form called a protist. And even though it has no brain or central nervous system, it can make some surprisingly sophisticated decisions.

Video Summary

If a slime mold was placed at one end of a maze and a piece of food at the other, it would easily be able to find that food using nothing more than its own tendrils. It would simply extend its tendrils into every corner of the maze until it can detect the food, and then retract all tendrils that did not find food. This leaves behind slime, which acts as a reminder that those spaces are dead ends. From there, the mold will grow along the shortest path available towards the food source. Researchers are now conducting experiments with this mold to better understand its decision making skills and use them as examples for future world endeavors.
