Summary

Story summary

University of Massachusetts Amherst researchers developed an artificial neuron that communicates with biological neurons.
It operates at voltages and energy levels similar to natural neurons, per Nature Communications.
Compared with earlier designs, it whispers at 0.1 volts, with ten times less voltage and a hundred times less power.
Protein nanowires grown by bacteria enable this lifelike interaction.
