IBM researcher builds a phase-change capable artificial neuron
Significantly, it's built of trusted materials and can scale down microscopically. Computers have long been compared to artificial brains, but now IBM has followed the comparison and built a working artificial neuron. The tech giant's research center in Zurich created 500 of them to simulate a signal transfer similar to how the process works in an organic brain. As other research in artificial signaling demonstrate, the real milestones are had when elements can be shrunk down to microscopic scale and still work. That's what makes IBM's accomplishment significant: their faux neurons are built out of well-known materials that can scale down to a few nanometers but can still activate with low energy, points out Ars Technica.
