6/12/18 Show feat. Chris Tokita on Division of Labor, Simulating Behavior and Scientists in Politics

This week, we feature Chris Tokita, graduate researcher in Princeton’s Ecology and Evolutionary Biology Department, who tells us about his work on division of labor and social networks. Computational biology lets us model behavior in a simulation: by picking a few rules and seeing if virtual groups behave like real groups in experiments, we can test what rules are most important for group functioning. Chris applies this strategy to clonal raider ants, which all have the same genetics but nonetheless form division of labor where some ants nurse, some forage, some clean… A simple rule where each ant feels a “threshold” for performing a task seems to explain this diversification, which makes the colony more successful. But there are unanswered questions concerning the clustering of insect social networks and the transfer of information through the colony that will keep Chris busy tuning his simulation—eventually, his studies might lead us to more generalizable facts about human society itself.

Listen through the end for the full story on Chris’s political work too, both at the federal Science and Technology Policy Institute and the local New Jersey General Assembly!

  1. Great program on my favorite local radio station WPRB! Not to take away from the need to regulate autonomous vehicles but there is a dire need for folks like Chris to engage with the public about the near catastrophic consequences of anthropogenic climate change. The American Physical Society had opined i 2015 : “… the connection between rising concentrations of atmospheric greenhouse gases and the increased warming of the global climate system is more compelling than ever.” but has now realized the need to frame the conversation on tackling climate change as a global energy challenge. (APS Public Policy Statement 17.1). Consider also this: a 2016 Pew Research Survey found only a modest and inconsistent correlation between increasing science knowledge and attitudes about climate and energy issues. In other words, how people connect their knowledge of science with their attitudes about climate change depends on their political orientation!
