This study measures the energetic cost of bacterial motility using microcalorimetry and finds it to be a significant portion of total metabolism during starvation.

This study shows marine bacteria are attracted to fucoidan at high concentrations, suggesting it guides them to macroalgal surfaces, influencing carbon cycling.

The paper shows how inherited flagellar structures coordinate swimming onset in E. coli cells by integrating transcriptional noise and sharpening it into a heritable decision.

The paper studies bacterial iron acquisition under low carbon conditions and finds that amino acids facilitate iron uptake by E. coli.

This paper demonstrates that heritable diel energy reserves in diatoms enhance growth by allowing rapid division during the dark phase, leading to a significant increase in population abundance.

The paper identifies an amoeboid phase in coccolithophores triggered by bacteria, which persists after bloom collapse and may provide bacterial resistance.

The paper identifies a risk-reward trade-off in motility endurance among copiotrophic marine bacteria, revealing two distinct strategies with genomic predictors.

The paper uses single-cell FRET measurements in E. coli to show signaling variability across and within cells, attributing it to stochastic enzyme activities and receptor-kinase dynamics.
