Access the Web Focus today!   Thesis Top Naughty, naughty atoms   pp1 - 2 Chris Toumey doi:10.1038/nnano.2012.247 What does the theory of atoms have to do with religious belief? Chris Toumey explains how historically the link between atomism and atheism has been quite strong. Research Highlights Top Our choice from the recent literature   p3 doi:10.1038/nnano.2012.250 News and Views Top Self-assembly: En route to patchy superlattices   pp5 - 6 Mathew M. Maye doi:10.1038/nnano.2012.244 The electrostatic interaction between protein cages and charged gold nanoparticles can be used to assemble nanoparticle superlattices with structures that have not been observed before in nature.

Fraser Stoddart doi:10.1038/nnano.2012.239 A supramolecular polymer made of thousands of bistable [c2]daisy chains amplifies individual nanometric displacements up to the micrometre-length scale, in a concerted process reminiscent of muscular cells. Superconductivity: The imaginary is real   pp10 - 11 Guy Deutscher doi:10.1038/nnano.2012.245 Experiments on nano-islands of a high-temperature superconductor reveal the presence of a small imaginary component of the superconducting order parameter.
