Creeping through mazes, repelling adversaries – the slow-motion smarts of slime moulds
To the naked eye, the organism Physarum polycephalum – commonly referred to as ‘slime mould’ – might seem an unexceptional creature, despite its bright-yellow glow, as its acellular existence is dedicated to tracking nutrients at a speed of 1mm per hour. But this protist’s surprising computational cunning becomes apparent when viewed in time-lapse, revealing a life form that seems to possess intelligence despite lacking a nervous system. Between 2009 and 2018, the UK artist and researcher Heather Barnett conducted a series of clever experiments in which she probed slime moulds’ capacities for forming complex tube networks and adjusting to obstacles. For this short film, Aeon Video compiled Barnett’s ‘creative collaborations’ with P polycephalum into a montage that builds in complexity, emphasising the slime moulds’ surprisingly sophisticated capacities for problem-solving.
