Animal cells can use elements or ions to generate electrical impulses. These impulses are then conveyed from one cell to another, traveling across cellular networks.
Theoretical physicists at Utrecht University, together with experimental physicists at Sogang University in South Korea, have succeeded in building an artificial synapse. This synapse works with water and salt and provides ...
