finding:model-predicted-intervention-two-drugs-and-a-dominant-negative-construct-broke-concordance-among-melanocytes-producing-first-partially-pigmented-animals-lobo-et-al-2017Model-predicted intervention (two drugs and a dominant negative construct) broke concordance among melanocytes, producing first partially-pigmented animals (Lobo et al. 2017)
Demonstrates that breaking collective decision-making can be achieved, separating the decision from its coordination across cells.

- Levin-led research showing bioelectric signals encode and control anatomical goal states in living systems.
- Cellular bioelectric patterns encode organ identity and developmental decisions at population level, demonstrated through drug/ion channel interventions that toggle phenotypes in all-or-none fashion (Levin group, 2009-2017).
