Slime Mold Video
This video is composed of a sequence of films created by John Tyler Bonner [5] in the 1940s to show the life cycle of the cellular slime mold [6], Dictyostelium discoideum . As only the second person to study slime molds, Bonner frequently encountered audiences who had never heard of, let alone seen, the unusual organism. He therefore decided to create a film to present at seminars in order to ...
متن کاملGalvanotaxis of Slime Mold
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 microa./mm.(2) Injury was produced by current densities of 8.0 to 12.0 microa./mm.(2) The negative galvanotactic response was not due to electr...
متن کاملSlime Mold Inspired Chemical Sounding
This paper describes the biological motivation, design and testing of a novel obstacle sensor system based on the chemical sounding mechanism observed in slime molds. The sensor system emits a volatile sounding chemical and adjacent obstacles reduce the dispersion of the chemical. The resulting increase in chemical concentration is detected and interpreted as indicating an obstacle. To demonstr...
متن کاملSlime Mold Team 1 Project Report
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 ...
متن کاملEmergent networks: A slime mold simulation
In a world where news are delivered in an instant around the world, where the population of a network service is around twice the one of the USA and where an natural catastrophe can lead to a chain reaction a reliable infrastructure is the key to survival. This insight has motivated a diverse group of researchers to seek understanding of the resilient infrastructure of nature surrounding our ev...
