Petra Levin joins TWiM to tell three stories from her laboratory: how starvation induces shrinkage of the bacterial cytoplasm; plasticity of E. coli cell wall and how it influences antibiotic resistance across different environments; and induction of antibiotic resistance by Triclosan.

On this episode, an electrochemical scaffold that delivers safe doses of hypochlorous acid to treat wound infections in humans, and a method for sampling and monitoring bacteria and viruses on surfaces using plain paper stickers.

Mark Martin returns to TWiM to discuss ways to increase diversity in our field, and the discovery of Borgs, giant extrachromosomal elements with the potential to augment methane oxidation.

Foodie TWiM reveals that bacteria in human saliva are major components of Ecuadorian indigenous beers, and an unusual E. coli that produces atypical light cream-colored colonies in chromogenic agar.
