    In biological systems, order typically emerges from out-of-equilibrium molecular processes that control both static patterns and dynamic changes. Now, the self-regulating assembly and disassembly of a synthetic system has been achieved on the micrometre scale, by coupling the growth of a DNA nanotube to a biochemical oscillator.

    The longstanding ‘polyelectrolyte theory of the gene’ proposes that a multiply charged backbone is the universal signature of all genetic polymer systems that support life. Now, the first tenable challenge to this theory has been mounted, through the successful engineering of enzymes which can synthesize and reverse-transcribe from an artificial, uncharged nucleic acid analogue.
