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

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

The paper studies spatial patterns in synthetic gene networks in E. coli colonies using statistical mechanics models and simulations, finding power-law scaling and anti-correlations.
