It could not escape my notice that your cover of 9 September (Nature 467, issue 7312; 2010) is dominated by a DNA molecule with a pronounced left-handed helical twist. In the structure originally proposed by James Watson and Francis Crick in your pages, however, the chains of DNA follow paired right-handed helices.

I suggest that this sketch of DNA, arguably the most iconic image ever published by Nature, be displayed prominently in your offices to prevent such unfortunate howlers being made in future.
