Irish researchers build a new DNA computer that runs inside a drop of water

UPDATE - follow-up to Scientists build a DNA computer that can perform calculations in a drop of water - livescience.com: Researchers in Ireland have built a new molecular computer that uses DNA strands to run calculations inside a single drop of water. Maynooth University experts created this system, which handles 100-bit calculations without needing any electricity. The computer relies on a technique called DNA origami, where strands of genetic material fold themselves into specific shapes to process information. This work appears in the journal Nature and sets a new record as the fastest and most complex DNA-based computing system made so far.
