Physarum polycephalum, a unicellular and multiheaded slime mould, can form highly efficient networks connecting separated food sources during the process of foraging. These adaptive exhibit unique characteristic in that they are optimized without control central consciousness. Inspired by this phenomenon, we present an exploration navigation strategy for swarm robots, which exploits cooperation...

This paper introduces BioComputer Music, an experimental one-piano duet between pianist and plasmodial slime mould Physarum polycephalum. This piece harnesses a system we have been developing, which we call BioComputer. BioComputer consists of an analogue circuit that encompasses components grown from the biological computing substrate Physarum polycephalum. Our system listens to the pianist an...

Tanacetum santolinoides, Essential Oil Composition, n-Hexane-Ether Extract Composition The essential oil of the aerial parts of Tanacetum santolinoides was analyzed by capillary GLC and GLC-MS. Altogether 30 components were identified. The main constituents were thymol (18%), trans-thujone (17.5%), trans-chrysanthenyl acetate (13.2%), cis-chrysanthenyl acetate (9.2%), umbellulone (9.7%) and 1,8...

The methanolic extract of aerial parts of Tanacetum vulgare L. (Asteraceae) and its fractions were investigated for antioxidant activity. The crude extract displayed DPPH radical scavenging effects with an EC50 value of 37 +/- 1.2 microg/mL (n=3). Activity-guided fractionations of the crude extract resulted in the isolation of three antioxidant compounds; 3,5-O-dicaffeoylquinic acid (3,5-DCQA),...

Many biological systems require extensive networks to transport resources and information. Biological networks must trade-off network efficiency with the risk of network failure. Yet, biological networks develop in the absence of centralised control from the interactions of many components. Moreover, many biological systems need to be able to adapt when conditions change and the network require...

In previous work the chemotaxis toward simple organic chemicals was assessed. We utilize the knowledge gained from these chemotactic assays to route Physarum polycephalum "signals" at a series of junctions. By applying chemical inputs at a simple T-junction we were able to reproducibly control the path taken by the plasmodium of P. Polycephalum. Where the chemoattractant farnesene was used at o...
