…According to Onuchic, bacteria usually do not cheat their friends and inform them by sending chemical messages about their true intensions. "We have developed for the first time a system level model of a large gene network to decipher the underlying principles of the bacteria game theory and how an internal network of genes and proteins is used to calculate risks in this complicated situation," he said.

… "Another interesting fact is that the same cells in the same environment, in this case, bacteria in the colony, can actually in a statistical matter choose two different outcomes: sporulation or competence. This leads us to speculate whether similar ideas can be extrapolated to explain the decisions of cells to develop cancer: Can a similar cell in a tissue make the decision to duplicate normally or to modify into a cancer cell? How does this stochastic process affect life, biology, evolution and disease is an interesting challenge that will be at the center of questions answered at the interface of the physical and life sciences."
