Population growth is primarily inhibited by processes other than resource depletion, leaving a sublinear signature across species

The paper shows that population growth slows sublinearly with density in most species, challenging the resource-depletion model and suggesting other inhibitory processes are at play.

Transcriptional competition biases the effects of second messengers in Escherichia coli

The paper shows that second messengers in E. coli affect gene expression through transcriptional competition, reshaping proteome allocation beyond individual regulatory effects.

Incoherent feedback from coupled amino acids and ribosome pools generates damped oscillations in growing E. coli

The paper develops a mechanistic model of bacterial growth that incorporates amino acid pools, ppGpp sensing, and transcriptional regulation, showing oscillatory dynamics during environmental changes.

Gradual entry into carbon starvation decreases the death rate of Escherichia coli

This study shows that gradual entry into carbon starvation reduces Escherichia coli death rates by allowing proteome adaptation, with a theoretical model supporting active gene up-regulation for survival.
