“…Физарум многоглавый не имеет мозга, центральной нервной системы, но тем не менее он имеет клеточный интеллект [54], который способен решать сложные задачи, например, такие, как нахождение кратчайшего пути между двумя точками в лабиринте. Слизевики любят овсяные хлопья и не любят свет.…”

“…Slime molds, particularly P. polycephalum, have been extensively studied due to their simplicity, the amoeboid-like behavior of the plasmodium, and their puzzle-solving ability. [16][17][18][19]21,35] Low stress threshold ECDA/C21 films were used to examine the migration and document the area explored by Physarum as seen in Figure 6A. When a slime mold is placed on a PDA film, migration by the slime mold induces the blue-to-red transition.…”

“…P. polycephalum has attracted significant interest in a variety of disciplines due to its ease of culturing, cytoplasmic streaming, ameboid locomotion, and unique demonstration of "intelligence" in maze solving and other demonstrations of cognition. [16][17][18][19] In the plasmodium phase of its lifecycle, it is highly migratory and exerts measurable shear forces. The traction forces of Physarum microplasmodia have been examined previously using traction force microscopy (TFM).…”

Polydiacetylene (PDA) Langmuir films are well known for their blue‐to‐red chromatic transitions in response to a variety of stimuli, including UV light, heat, bio‐molecule bindings, and mechanical stress. In this work, the ability to tune PDA Langmuir films to exhibit discrete chromatic transitions in response to applied mechanical stress is detailed. Normal and shear‐induced transitions are quantified using the Surface Forces Apparatus and established to be binary and tunable as a function of film formation conditions. Both monomer alkyl tail length and metal cations are used to manipulate the chromatic transition force threshold to enable discrete force sensing from ≈50 to ≈500 nN µm−2 for normal loading and ≈2 to ≈40 nN µm−2 for shear‐induced transitions, which are appropriate for biological cells. The utility of PDA thin‐film sensors is demonstrated with the slime mold Physarum polycephalum. The fluorescence readout of the films enabled: the area explored by Physarum to be visualized, the forces involved in locomotion to be quantified, and revealed novel puncta formation potentially associated with Physarum sampling its environment.

“…As a pictorial view shown in Figure 1, Physarum polycephalum grows by building a network that links several food points. Recently, Physarum has arisen as a fascinating illustration of biological computation through morphogenesis [19,20]. For convenience in developing a Physarum-inspired BLN design, firstly, we review relevant works and the mathematical model of Physarum in this section.…”

Physarum-Inspired Bicycle Lane Network Design in a Congested Megacity

et al. 2021

Improvement of mobility, especially environment-friendly green mobility, is challenging in existing megacities due to road network complexity and space constraints. Endorsing the bicycle lane network (BLN) in congested megacities is a promising option to foster green mobility. This research presents a novel bioinspired network design method that considers various constraints and preferences related to the megacity for designing an optimal BLN. The proposed method is inspired by natural Physarum polycephalum, a brainless, multi-headed single-celled organism, which is capable of developing a reticulated network of complex foraging behaviors in pursuit of food. The mathematical model of Physarum foraging behavior is adapted to maneuver various BLN constraints in megacity contexts in designing the optimal BLN. The Physarum-inspired BLN method is applied to two case studies on the megacity Dhaka for designing BLNs: the first one covers congested central city area, and the second one covers a broader area that includes major locations of the city. The obtained BLNs were evaluated comparing their available routes between different locations with the existing vehicle routes of the city in terms of distance and required travel times in different time periods, and the BLN routes were found to be suitable alternatives for avoiding congested main roads. The expected travel time using BLNs is shorter than other transport (e.g., car and public bus); additionally, at glance, the average travel speed on BLNs is almost double that of public buses in peak hours. Finally, the designed BLNs are promising for environment-friendly and healthy mobility.
