Experiment and theory unite at last in debate over microbial nanowires

Scientific debate has been hot lately about whether microbial nanowires, the specialized electrical pili of the mud-dwelling anaerobic bacterium Geobacter sulfurreducens, truly possess metallic-like conductivity as its discoverers claim. But now University of Massachusetts Amherst microbiologist Derek Lovley, with postdoctoral researcher Nikhil Malvankar and colleagues, say they have settled the dispute between theoretical and experimental scientists by devising a combination of new experiments and better theoretical modeling.
