Researchers Build Evolving Brain Computer?
destinyland writes “We have mimicked how neurons behave in the brain,” announces an international research team from Japan and Michigan Tech. They’ve built an “evolutionary circuit” in a molecular computer that evolves to solve complex problems, and the molecular computer also exhibits brain-like massive parallel processing. “The neat part is, approximately 300 molecules talk with each other at a time during information processing,” says physicist Ranjit Pati of Michigan Tech. When viewed with a scanning tunneling microscope, the evolving patterns bear an uncanny resemblance to the human brain as seen by a Functional MRI. Using the electrically-charged tip of a tunneling microscope, they’ve individually set molecules to a desired state, essentially writing data to the system. And while conventional computers are typically built using two-state (0, 1) transistors, the molecular layer is built using a hexagonal molecule, and can switch among four conducting states — 0, 1, 2 and 3, suggesting it may ultimately have more AI potential than quantum computing.”
