Two results on slime mold computations [PDF]
Theoretical Computer Science, 2019 We present two results on slime mold computations. In wet-lab experiments (Nature'00) by Nakagaki et al. the slime mold Physarum polycephalum demonstrated its ability to solve shortest path problems. Biologists proposed a mathematical model, a system of differential equations, for the slime's adaption process (J. Theoretical Biology'07).

GALVANOTAXIS OF SLIME MOLD [PDF]
Journal of General Physiology, 1951 The plasmodium of Physarum polycephalum reacts to direct current by migration toward the cathode. Cathodal migration was obtained upon a variety of substrata such as baked clay, paper, cellophane, and agar with a current density in the substratum of 1.0 µa./mm.2 Injury was produced by current densities of 8.0 to 12.0 µa./mm.2 The negative galvanotactic

Signal transduction in the cellular slime molds [PDF]
Molecular and Cellular Endocrinology, 1982 Intercellular communication in higher organisms depends on the central nervous system and hormones. Simple organisms such as the cellular slime molds communicate intercellularly only by using hormone-like signals. The most intensively studied species of the cellular slime molds is Dictyostelium discoideum.

Origin and evolution of the slime molds (Mycetozoa) [PDF]
Proceedings of the National Academy of Sciences, 1997 The Mycetozoa include the cellular (dictyostelid), acellular (myxogastrid), and protostelid slime molds. However, available molecular data are in disagreement on both the monophyly and phylogenetic position of the group. Ribosomal RNA trees show the myxogastrid and dictyostelid slime molds as unrelated early branching lineages, but actin ...

A slime mold’s remembrance of things past [PDF]
Proceedings of the National Academy of Sciences, 2021 The paper “Encoding memory in tube diameter hierarchy of living flow network” by Kramar and Alim (1) may be an example of the unbridgeable gulf between physics and biology; I am not sure, but it may be. Kramar and Alim study how the giant unicellular slime mold Physarum polycephalum develops an associative memory by adjusting wall stiffness and removal

Self-starting slime mold [PDF]
The Journal of Cell Biology, 2007 ![Graphic][1] PI3K (arrows) accumulates in the stretching pseudopods of a slithering cell. Hungry cells often wander around, hunting for something tasty. On page [185][2], Sasaki et al.

, 2021 Please note that this was a preliminary version of the finally published manuscript. See newer version. Bark was collected from living trees in Chile and cultured in moist chamber cultures. Together with field collections, 18 myxomycete species amd one acrasian were recorded.

The American Biology Teacher, 1982 The plasmodial slime molds, or Myxomycetes, are a small (about 450 known species), rather insignificant, but widely distributed group of organisms having characteristics of both plants and animals. They produce fruiting bodies and spores similar to those of many fungi.
