katch wreck`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.`

Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
To "breathe" in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons (produced during the "burning" of nutrients) to electric hairs called nanowires projecting from their surface.

Extracellular cytochrome nanowires appear to be ubiquitous in microbes
A Geobacter bacteria isolated from a contaminated ditch in Oklahoma has an unusual appendage—a long extracellular nanowire that can conduct electricity. The electron transport chain in this nanowire carries electrons from the bacteria to an insoluble external electron acceptor to help the microbe make energy. Such long-range electron transfers at a micron-scale are thought to have played an important role in microbial metabolism on the early Earth.

An Ultra-Stable Protein Nanowire Made by Bacteria Provides Clues to Combating Climate Change
Bacteria deep in the soil need "nanowires" made up of cytochrome OmcZ to export electrons to extracellular acceptors in order to survive without oxygen. Our cryo-EM OmcZ architecture explains how bacteria make nanowires on demand and why only OmcZ nanowires show extremely high electron conductivity.
