Legionella pneumophila can be inhibited by its own antimicrobial, HGA (homogentisic acid), but its density-dependent resistance to HGA restricts the potential for self-harm.

Some forms of positive density-dependence can favor species coexistence even if competitive species benefit the most from positive density-dependence.

Seasonal variation in resources causes opposing episodes of selection on body size, which interact with density dependence to influence population dynamics.

TRAF3, a negative regulator of noncanonical NF-κB signaling, maintains epithelial cell quiescence at confluence, and its loss triggers upregulation of immunity genes and prevents entry into G0 at high cell density.

Arid1a loss in the pancreas enables an irreversible reprogramming of cell fate that is dependent on both cellular and genetic context.

Timing in the formation of neurons influences synaptic connectivity.

Estrogen receptor alpha in the hypothalamus is required for the effects of chronic tamoxifen treament on gene expression, thermoregulation, bone, and movement in mice.

Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.

Microtubule networks in frog egg extracts can spontaneously contract in a manner that can be quantitatively described by an active fluid model.

Collapse of bacterial communities containing antibiotic-resistant and susceptible cells can be driven by increased population size or delayed drug exposure.
