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.

The TWiMmers get cozy with symbionts: bacteria that allow a giant shipworm to oxidize sulfur, and algae that live within salamander cells.
