We implement Kolmogorov-Uspensky machine on a plasmodium of true slime mold {\em Physarum polycephalum}. We provide experimental findings on realization of the machine instructions, illustrate basic operations, and elements of programming.

During two years of passage, several myxamoebal strains of Physarum polycephalum changed with regard to their properties in crosses and plaque morphology. These changes have been correlated with increased nuclear deoxyribonucleic acid content.

The Physarum Polycephalum, or true slime mold, is a large multi-nuclear cell which uses a network of tube-like structures called pseudopodia to connect food sources and ensure its survival. Much study has been done on the behavior and formation of the pseudopodia, with a special focus on the tendency to choose an efficient path between the food sources [1, 2, 4, 6, 9, 10, 12, 13]. When food is ...

Biological systems that have been subjected to vast time periods of evolution, have provided numerous times inspiration for problem solving techniques. These systems have evolved to survive in harsh environments, thus they provide more efficient solutions than the conventional methods. The inspiration of this study was based on the computing abilities that Physarum Polycephalum performs on grap...

Purified antibodies from an antiserum against S-phase proteins of the myxomycete Physarum polycephalum were attached to protein-A-Sepharose CL-4B. A late G2-phase extract that contained a mitosis-stimulating protein was applied to this immunoadsorbent, and the mitosis-stimulating protein was enriched by a factor of ten. This protein, which is present in the cell in low amounts, is synthesized i...

Physarumpolycephalum is an acellular slime mould whose histones are of general interest because they allow comparisons to be made between lower eukaryote and higher eukaryote histones and, perhaps more importantly, they provide a unique opportunity for the study of histone changes in the mitotic cycle, which is naturally synchronous in P. polycephalum plasmodia, and during differentiation. Stud...

Slime mould Physarum polycephalum is a single cell visible by the unaided eye. Let the slime mould span two electrodes with a single protoplasmic tube: if the tube is heated to approximately ≈40 °C, the electrical resistance of the protoplasmic tube increases from ≈3 MΩ to ≈10,000 MΩ. The organism's resistance is not proportional nor correlated to the temperature of its environment. Slime mould...

When two food sources are presented to the slime mold Physarum in the dark, a thick tube for absorbing nutrients is formed that connects the food sources through the shortest route. When the light-avoiding organism is partially illuminated, however, the tube connecting the food sources follows a different route. Defining risk as the experimentally measurable rate of light-avoiding movement, the...

Spores of race 2 but not of race 1 of Colletotrichum lagenarium are ingested by myxamoebas of strain NE-30 of the slime mold Acrasis rosea. Sporulating colonies of three heterocaryons of C. lagenarium involving auxotrophic strains with different color markers of races 1 and 2 were inoculated with myxamoebas. Although spores of race 1 produced on homocaryons were not ingested by the myxamoebas, ...
