The chemorepellent effect of metformin limits bacterial penetration into mammalian mucus by altering bacterial motility

This study shows metformin acts as a bacterial chemorepellent, reducing bacterial penetration into mucus by altering motility and chemotaxis.

Collective motion of bacteria promotes soil water transport

The paper shows that bacterial motility reduces surface tension in soil, enhancing water infiltration and rewetting.

Disruption of IgA-mediated aggregation at weaning favors mucus encroachment by commensal bacteria

This study shows that IgA-mediated bacterial aggregation at weaning prevents mucus penetration by commensal bacteria, while its disruption allows deeper bacterial encroachment.

Run-and-tumble dynamics of E. coli is governed by its mechanical properties

The paper models E. coli run-and-tumble behavior using fluid dynamics simulations and experiments, finding that flagellar rigidity and arrangement, not number, primarily influence motility.

Medium-assisted tumbling controls bacteria exploration in a complex fluid

This study investigates how E. coli bacteria navigate complex non-Newtonian fluids, finding that mechanical properties of the medium override their natural motility strategies.
