The cast of TWiM reveals how uropathogenic E. coli use a binding protein to treat copper as a nutrient or a toxin, and Antarctic soil bacteria that survive on trace atmospheric gases.

The TWiM team ventures into preprint space with an analysis of type VI secretion across human gut microbiomes, and provide insight into urinary tract infection: how bladder exposure to a member of the vaginal microbiota triggers E. coli egress from latent reservoirs.

Michael and Vincent present Spotlights, brief reviews of classic papers in the Journal of Bacteriology, and explain how a single bacterial species can reverse autism-like social deficits in the offspring of obese mice.

Harris joins Vincent, Elio, and Michael to describe multiplex automated genome engineering, a method for targeting many modifications in a population of bacterial cells.
