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

Electric Field Driven Soft Morphing Matter

Advanced Materials, EarlyView.
This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...

Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

Advanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.

A Slime Mold-Ant Colony Fusion Algorithm for Solving Traveling Salesman Problem

IEEE Access, 2020
The Ant Colony Optimization (ACO) is easy to fall into the local optimum and its convergence speed is slow in solving the Travelling Salesman Problem (TSP). Therefore, a Slime Mold-Ant Colony Fusion Algorithm (SMACFA) is proposed in this paper.

Multiarmed Spirals in Excitable Media [PDF]

, 1997
Numerical studies of the properties of multiarmed spirals show that they can form spontaneously in low excitability media. The maximum number of arms in a multiarmed spiral is proportional to the ratio of the single spiral period to the refractoriness of
