TWiM 287: When Replicas Do Not Replicate
TWiM investigates the high variability in the rate and amount of current production from microbial fuel cells, and how bacteria link their growth rate to external nutrient conditions via a protein that functions as a cellular rheostat.

TWiM 285: How plague got deadly
TWiM reveals a new type of satellite virus that requires only phage tails for producing infectious virus particles, and that highly virulent plague bacteria differs from its innocuous enteric predecessor by its resistance to lysis by human complement.
