<< As in all communities, cohabiting bacteria need ways to exchange messages. Biologists have known for decades that bacteria can use chemical cues to coordinate their behavior. >>

AA << are now finding that bacteria in biofilms can also talk to one another electrically. Biofilms appear to use electrically charged particles to organize and synchronize activities across large expanses. This electrical exchange has proved so powerful that biofilms even use it to recruit new bacteria from their surroundings, and to negotiate with neighboring biofilms for their mutual well-being. >>

<< Step by step we find that all the things we think bacteria don’t do, they actually do, [..] It’s displacing us from our pedestal. >> Ned Wingreen.

intrigante qui l'idea di una Intelligenza Artificiale che, dalle relativamente comode e veloci osservazioni sull'evoluzione di colonie batteriche sotto differenti condizioni, sia in grado di circoscrivere pattern comportamentali di interesse per la modellizzazione (e previsione)  di comunita' altre ...
