    • The physics of bacterial decision making 

      Ben-Jacob, Eshel; Lu, Mingyang; Schultz, Daniel; Onuchic, José N. (2014)
      The choice that bacteria make between sporulation and competence when subjected to stress provides a prototypical example of collective cell fate determination that is stochastic on the individual cell level, yet predictable ...
