The construction cylinder block of sprightliness just get a little weird . Natural DNA strands are also a favorite construction tool for nano - engineers because of its tendency for individual strands to automatically bind to one another , snapping into a orbit of useful shape , like the famed double whorl intention . Now scientists at Arizona State University have taken things to the next level and make GNA ( that’sGlycerol Nucleic Acid ) . More heat - tolerant and capable to twist in ways its innate cousin ca n’t , scientists need to apply GNA as a ego - foregather scaffold for the nano - automaton of the future . No countersign on the danger of GNA escaping from the lab and spawn a race of killer man-made , ego - assembling extraterrestrial . ( fromEurekAlert , figure : TurboSquid )
