The cast of TWiM reveals how uropathogenic E. coli use a binding protein to treat copper as a nutrient or a toxin, and Antarctic soil bacteria that survive on trace atmospheric gases.

Vincent and Elio discuss the reason for poor efficacy of one of the influenza virus vaccines, and using a hyperthermophilic anaerobe to produce hydrogen from fruit and vegetable wastes in seawater.

The TWiM team discusses the use of copper on exercise weights to reduce bacterial burden, and the mechanism of antigenic variation by which a fungus that causes severe pneumonia escapes the immune system.

From Indiana University, Vincent speaks with Ankur, Julia, and Xindan about their careers and their work on horizontal gene transfer, quorum sensing, and chromosome organization in bacteria.
