# rmx-s-cell-signals: susceptibility to misperception: sensory illusion to self-destruct

<< (..) even brainless single-celled yeast have sensory biases that can be hacked by a carefully engineered illusion >>

<< (..) yeast cells falsely perceive a specifically timed pattern of stress – caused by alternating between low and mildly increased sodium levelsas a massive, continuously increasing ramp of stress. In response, the microbes end up over-responding and killing themselves >>
