MTS63 - Jeff Gralnick - I Sing the Microbe Electric

All life hums with electricity, from our heartbeats to the electrons that flow to the oxygen we breathe. But some bacteria are electricians par excellence, generating electric currents in the soil and water.

In this podcast, I talk to microbe-electricity expert Jeff Gralnick of the University of Minnesota about the biology behind these currents, and how engineers may be able to harness it to power technology.
