From the Japanese 八文字 for eight letters, researchers at Harvard are reported to have successful synthesised a DNA analogue that incorporates additional four artificial base-pairs to complement the four natural ones that assumes the familiar double-helix structure. For moment, this potential expanded genetic repertoire could not escape the laboratory as it requires constant chemical nourishment that does not occur in natural biology but the potential is there for some incredible applications—including the search for extra-terrestrial life, pathology, enhanced data storage and nano-scale engineering.
