Functioning Synapse Created Using Carbon Nanotubes [link]
Engineering researchers the University of Southern California have made a significant breakthrough in the use of nanotechnologies for the construction of a synthetic brain. They have built a carbon nanotube synapse circuit whose behavior in tests reproduces the function of a neuron, the building block of the brain.
A very promising development for both human and artificial intelligence research.
And against the argument for a separate consciousness, if humans can be perfectly replicated.
