During growth in biofilms and host infection, the opportunistic pathogen Pseudomonas aeruginosa employs respiratory heterocomplexes that support extracellular electron shuttling and pathogenicity.

During Staphylococcus aureus infections, bacterial cells bifurcate into distinct, specialized cell types that localize physically in different colonization tissues to simultaneously generate different infection types.

Publication bias, in which positive results are preferentially reported by authors and published by journals, can restrict the visibility of evidence against false claims and allow such claims to be canonized inappropriately as facts.

An analysis of more than 3000 randomized controlled trials published in JAMA, the Lancet and NEJM has identified 396 medical reversals.

The development of the tsetse fly immune system relies on a cue from an endosymbiotic bacterium called Wigglesworthia.

The house sparrow, one of the most ubiquitous birds in the world, is now used extensively in studies across disciplines in the life sciences.

The turquoise killifish from ephemeral pools in African savannah combines extremely short lifespan with a standard vertebrate body plan – ideal attributes for a laboratory animal.

A better understanding of the remarkable diversity, natural history and complex ecology of E. coli in the wild could shed new light on its biology and role in disease, and further expand its many uses as a model organism.

A data-driven within-host model reveals that different antibiotics are associated with divergent effects on antibiotic resistance carriage and abundance in hospitalised patients, with important implications for antibiotic stewardship.

Exclusion of participants in tasks with a learning element can introduce substantial bias and needs to be carefully considered and transparently reported and justified.
