This paper shows that a synthetic gene circuit can break a growth rate plateau in E. coli by selectively suppressing slow-growing cells, leading to faster growth.

The paper shows that prolonged plasmid persistence after antibiotic treatment is due to dynamical memory, not horizontal transfer or low plasmid cost.

The paper shows that asynchronous abundance fluctuations can cause large genotype frequency changes in microbial populations, distinct from genetic drift.
