TWiM continues its food arc with an examination of the effect of peroxyacetic acid spray on the microbiome and sensory properties of beef, and explores asymmetry of the cell division machinery during sporulation.

The TWiM team reviews how variants of P. aeruginosa survive antimicrobial treatment, and a decrease in the antimicrobial resistance of the gut microbiome in the presence of the fungus C. albicans.

TWiM reveals that methane-producing bacteria might survive beneath the surface of Mars, and identification of a cytopathogenic toxin in a bacterium associated with preterm birth.
