Researchers find a single-celled slime mold with no nervous system that remembers food locations

The ability to store and recover information gives an organism a clear advantage when searching for food or avoiding harmful environments, and has been traditionally linked to organisms that have a nervous system. A new study authored by Mirna Kramar (MPIDS) and Prof. Karen Alim (TUM and MPIDS) challenges this view by uncovering surprising abilities of a highly dynamic, single-celled organism to store and retrieve information about its environment.

Physarum polycephalum has been puzzling researchers for many decades. Existing at the crossroads between the kingdoms of animals, plants and fungi, this unique organism provides insight into the early evolutionary history of eukaryotes. Its body is a giant single cell made up of interconnected tubes that form intricate networks. This single amoeba-like cell may stretch several centimeters or even meters, featuring as the largest cell on earth in the Guinness Book of World Records.

The striking abilities of the slime mold to solve complex problems such as finding the shortest path through a maze earned it the attribute "intelligent," intrigued the research community and kindled questions about decision making on the most basic levels of life. The decision-making ability of Physarum is especially fascinating given that its tubular network constantly undergoes fast reorganization—growing and disintegrating its tubes—while completely lacking an organizing center. The researchers discovered that the organism weaves memories of food encounters directly into the architecture of the network-like body and uses the stored information when making future decisions.

To find out what is going on, the researchers combine microscopic observations of the adaption of the tubular network with theoretical modeling. An encounter with food triggers the release of a chemical that travels from the location where food was found throughout the organism and softens the tubes in the network, making the whole organism reorient its migration towards the food.

All slime molds are single cells during the plasmodial stage.
The article is needless as this one covered the same material in better detail. https://www.wired.com/story/slime-molds-rememberbut-do-they-learn/

Your post is useless as this one has more information.

I had a fun Science Teacher back in Grade School, who would have said that description of the single celled slime mold sounded just like some of his students!

This just in: Joe Biden declares that single-celled slime molds are eligible to vote. “After all, they are people too,” the President said.

Besides experiments with worms trained with stimuli being fed to non-trained worms to see if they learned through cannibalism, he was also the 10th victim of the unabomber.
