Damage dynamics in single E. coli and the role of chance in the timing of cell death

The paper measures damage dynamics in individual E. coli cells under carbon starvation and finds that stochastic noise amplification, not initial conditions, drives lifespan variation, with increasing determinism over time.

Two stochastic processes shape diverse senescence patterns in a single-cell organism

The paper shows that senescence in Escherichia coli is shaped by two stochastic processes: random cellular deterioration and asymmetric transmission of an unknown factor during cell division.
