Similarities And Differences

Slime mould Physarum polycephalum builds up sophisticated networks to transport nutrients between distant parts of its extended body. The slime mould’s protoplasmic network is optimised for maximum coverage of nutrients yet minimum energy spent on transportation of the intra-cellular material. In laboratory experiments with P. polycephalum we represent Canadian major urban areas with rolled oats and inoculated slime mould in the Toronto area. The plasmodium spans the urban areas with its network of protoplasmic tubes. The authors uncover similarities and differences between the protoplasmic network and the Canadian national highway network, analyse the networks in terms of proximity graphs and evaluate slime mould’s network response to contamination.

The Mind

Radical enactivism (REC) and similar embodied and enactive approaches to the mind deny that cognition is fundamentally representational, skull-bound and mechanistic in its organisation. In this article, I argue that modellers may still adopt a mechanistic strategy to produce explanations that are compatible with REC. This argument is scaffolded by a multi-agent model of the true slime mould Physarum polycephalum.

Lower Eukaryote

Starvation-induced differentiation of the slime mould Physarum polycephalum is accompanied by continuous methylation of DNA. No stable changes in the overall level of DNA methylation are evident, but a gene known to be transcribed specifically during differentiation is subject to increased methylation. Inhibitors of DNA methylation preclude differentiation of P. polycephalum, although they are only marginally inhibitory to normal growth. Taken together these results indicate that methylation of DNA is involved in differentiation of this lower eukaryote.
