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.

The microbophiles investigate the ratio of bacterial to human cells in our bodies, and how placing solar panels on a bacterium enables it to carry out photosynthesis.
