ScienceDaily (Dec. 13, 2009) — Scientists studying how bacteria under stress collectively weigh and initiate different survival strategies say they have gained new insights into how humans make strategic decisions that affect their health, wealth and the fate of others in society.
...
Each bacterium in the colony communicates via chemical messages and performs a sophisticated decision making process using a specialized network of genes and proteins. Modeling this complex interplay of genes and proteins by the bacteria enabled the scientists to assess the pros and cons of different choices in game theory, a branch of mathematics that attempts to model decision making by humans, in which an individual's success in making choices depends on the choices of others.

This has applications to human society because many people encounter similar dilemmas during their own lives. For example, should people ignore side effects and vaccinate against a new potentially lethal virus or should they not vaccinate and take the risk of being infected with the possible consequences?
