`Here, we demonstrate artificial neurons that not only closely emulate biological neurons in functions but also match their parameters in key aspects such as signal amplitude, spiking energy, temporal features, and frequency response. Moreover, these artificial neurons can be modulated by extracellular chemical species in a manner consistent with neuromodulation in biological neurons.`

Accelerated Microbial Corrosion by #Magnetite and Electrically Conductive Pili through Direct Fe0-to-Microbe Electron Transfer https://onlinelibrary.wiley.com/doi/10.1002/anie.202309005

"#Iron is well-known for #rusting... Some #bacteria are able to decompose Fe anaerobically in a process referred to as #electrobiocorrosion. The sediment-dwelling #bacterium #Geobacter sulfurreducens uses electrically conductive #protein threads for this purpose"

Structure of #Geobacter cytochrome OmcZ identifies mechanism of nanowire assembly and conductivity https://www.nature.com/articles/s41564-022-01315-5

#Bacteria deep in the #soil need #nanowires made up of #cytochrome OmcZ to export electrons to extracellular acceptors in order to survive without oxygen. New research explains how bacteria make nanowires on demand and why only OmcZ nanowires show extremely high electron #conductivity.
