The single-celled Physarum polcephalum, or slime mold, does not have a brain or nervous system, but is able to remember the location of a food source, a new study reveals. German scientist sound the bright yellow slime mold records where its last meal was by changing the shape of its tubular tendrils. If it encounters food while weaving around an environment, the mold will keep its specific structure in that area to know where to return to feast. The latest study builds on the'amazing' skills of the yellow mold, which can also solve mazes and perform other tasks that require intelligence. New research suggests P. polycephalum, a bright yellow slime mold with no brain or nervous system, 'remembers' records where a food source is by restructuring the shape of its tubular tendrils.
