Close-up view of the nuclear periphery Cell biologists would like to be able to visualize complexes inside cells at molecular resolution. Several limitations, however, have prevented the field from realizing this goal. The thickness of most cells precludes cryo-electron tomography, a technique which itself does not provide sufficient contrast. Mahamid et al. successfully combined recent advances on both fronts to analyze structures in situ at the periphery of the nucleus. Their images reveal features that inform our understanding of the native organization of nuclear pores and of the nuclear lamina. Science , this issue p. 969
