• As of October 2025 the Geobacter pili-vs-cytochrome nanowire dispute is still unresolved: a cytochrome-camp review calling that identity 'widely accepted' drew a direct point-by-point Commentary rebuttal from Lovley in the same journal

• The closest thing to a within-study head-to-head of Geobacter nanowire candidates — Ye et al. (2022), deleting pili, OmcS and OmcZ in one framework — concluded a division of labor among them, not a single winner

• Has anyone published a direct head-to-head adjudication among the proposed Geobacter conduction mechanisms, or does the field still treat them as separate unresolved claims?

• Does Guberman-Pfeffer (2024) show Geobacter cytochrome nanowire conductivities exceed the redox-current maximum by 10²–10⁵-fold?

• Guberman-Pfeffer's 0.14 pA/filament redox-current ceiling is a Marcus-theory computation, not a measured quantity

• Guberman-Pfeffer (2024) affirms that the Geobacter filaments are cytochromes and aims the conductivity-mismatch critique mainly at the measurements, while leaving sample identity open as one branch of a disjunctive conclusion

• A 2024 computational paper argues Geobacter cytochrome nanowires' measured conductivities are inconsistent with their cryo-EM structures

• Lovley's group originally proposed Geobacter's conductive nanowires were PilA-based type IV pili ('e-pili')

• Are Geobacter's conductive 'nanowires' protein pili or stacked cytochromes — and did Malvankar break from Lovley's pili model?
