TWiM 32: Not the shadow biosphere

3 May 2012

On episode #32 of the science show This Week in Microbiology, Vincent, Elio and Michael speak with Rosie Redfield about her evidence that a bacterium cannot grow on arsenic instead of phosphorus.

If you only listen to one episode of TWiM all year, make it this one – Rosie is terrific!
