Connectomics, the comprehensive mapping of neural circuits at nanoscale resolution, has historically relied on electron microscopy (EM), both transmission (TEM) and scanning (SEM). However, as connectomics scales towards larger brain volumes and whole mammalian brains, substantial technical challenges emerge. Here, we highlight key challenges and advancing approaches that hold promise, particularly those that integrate three-dimensional, multi-resolution and time-resolved imaging to capture both long-range and local wiring, down to supramolecular resolution.

Two-photon calcium imaging and electron microscopy were used to explore the relationship between structure and function in mouse primary visual cortex, showing that layer 2/3 neurons are connected in subnetworks, that pyramidal neurons with similar orientation selectivity preferentially form synapses with each other, and that neurons with similar orientation tuning form larger synapses; this study exemplifies functional connectomics as a powerful method for studying the organizational logic of cortical networks.

N-Myc fuels neuroendocrine prostate cancer. Here, the authors describe how targeting HSP70, a major N-Myc partner, coordinates with STUB1 to facilitate the degradation of N-Myc. This process slows neuroendocrine prostate cancer growth, improves the efficacy of Aurora Kinase A inhibitors, and reduces neuroendocrine pathway activity.

The complete DNA sequence of the yeast Saccharomyces cerevisiae chromosome IV has been determined. Apart from chromosome XII, which contains the 1–2 Mb rDNA cluster, chromosome IV is the longest S. cerevisiae chromosome. It was split into three parts, which were sequenced by a consortium from the European Community, the Sanger Centre, and groups from St Louis and Stanford in the United States. The sequence of 1,531,974 base pairs contains 796 predicted or known genes, 318 (39.9%) of which have been previously identified. Of the 478 new genes, 225 (28.3%) are homologous to previously identified genes and 253 (32%) have unknown functions or correspond to spurious open reading frames (ORFs). On average there is one gene approximately every two kilobases. Superimposed on alternating regional variations in G+C composition, there is a large central domain with a lower G+C content that contains all the yeast transposon (Ty) elements and most of the tRNA genes. Chromosome IV shares with chromosomes II, V, XII, XIII and XV some long clustered duplications which partly explain its origin.

This directory was made possible by a unique international collaboration between the 633 scientists whose names appear below. It represents both the first published description of the complete sequence of most chromsomes from Saccharomyces cerevisiae, and the first published overview of the entire sequence. As such, the authors would like future papers referring to the entire sequence and/or its contents to cite this directory; future papers referring to the sequence of individual chromosomes should refer to the papers listed at the head of page 9. The authors’ affiliations appear in the papers describing the individual chromosomes.
