A new molecular computer uses an organic molecular layer and can evolve to solve complex problems, similar to neurons.
…Interestingly, the evolving patterns generated on the molecular layer when viewed with a scanning tunneling microscope bear an uncanny resemblance to fMRI images of various events in the human brain. The researchers next used the electrically charged tip of the scanning tunneling microscope to individually set molecules in the top layer to a desired state, essentially writing data into the system.
Molecular computing is most frequently associated with DNA computing: custom-synthesized DNA strands are combined with enzymes to create output strands. DNA computing is limited by its ability to return only yes-or-no answers (0, 1) like a binary computer one strand is longer than another. This results in static circuits that are unable to evolve. In contrast, the electrical circuits of our brains are dynamic, ever-changing and evolving networks of neurons that process events in parallel. While conventional computers are typically built using two-state (0, 1) transistors, the molecular layer is built using a…
