Just how can such contortion be secure despite the well-known active matter instability? Below, we check out a situation where the gradient of a scalar area specifies active anisotropic stress and anxieties in the system. We find that the homogeneously deforming state is stable in the extensile situation, yet unpredictable in the contractile situation. Intriguingly, while there are numerous examples for extensile cells in nature, we could so much not identify any type of example for the contractile case. Our outcomes direct to a possible new developmental concept in biology that is straight rooted in active matter physics.
