Biofilms move electrons long distances across two distinct layers
Bacteria can move electrons at least half a millimeter across a scaffolding made by themselves, of themselves, even under starving conditions. This new finding challenges conventional wisdom, which held that electrical resistance within bacterial biofilms - robust structures held together by a strong matrix - would restrict long-range electron transfer.
