Flexi Says: New research suggests that slime molds can remember the location of food by changing the diameter of the tendrils in its plasmodium network. When a plasmodium forms to search for food in its environment, it sends out a fractal network of tiny tube-like tendrils. In areas where tendrils locate food, those tendrils expand in diameter. In areas where tendrils do not find food, the tendrils shrink or even disappear. These differences persist even when the slime mold is done feeding. This retains a type of memory which allows the slime mold to "know" what areas in the environment contain likely food sources and what areas do not.
