Physics and physiology determine strategies of bacterial investment in flagellar motility

The paper shows that bacterial investment in flagellar motility is constrained by hydrodynamics and fitness costs, with E. coli strains maximizing motility under nutrient-rich conditions.

Experimental evolution of a reduced bacterial chemotaxis network

This study uses experimental evolution to test the necessity of chemotaxis pathway components in E. coli, finding that core components are essential but some auxiliary proteins can be compensated for.

Active density fluctuations in bacterial binary mixtures

The paper studies how motility-driven physical interactions shape bacterial communities by showing non-motile bacteria form density fluctuations when mixed with motile Escherichia coli under physiological conditions.

Exercise Training Remodels Adipocyte-Specific Extracellular Matrix Proteins and Alters Innervation and Vascularization in Inguinal White Adipose Tissue (iWAT)

This study shows that exercise training remodels iWAT ECM, increases vascularization and innervation, and alters adipocyte subpopulations in male mice.

Dependence of diffusion in Escherichia coli cytoplasm on protein size, environmental conditions and cell growth

The paper investigates protein diffusion in E. coli cytoplasm using FCS and models, finding that diffusion depends on protein size, environmental conditions, and cell growth, with viscosity changes affecting all sizes proportionally.

Chemotactic behavior of Escherichia coli at high cell density

This study investigates how high cell density affects chemotactic behavior in Escherichia coli, finding that collective motion suppresses chemotaxis at higher densities.
