    A subterranean species that seems to be cancer-proof is providing promising clues on how we might prevent the disease in humans.

    As part of the modENCODE initiative, which aims to characterize functional DNA elements in D. melanogaster and C. elegans, this study created a map of the regulatory part of the fruitfly genome. On the basis of the developmental dynamics of chromatin modifications, polymerase and transcription factor occupancy this work defines a vast array of putative regulatory elements, such as enhancers, promoters, insulators and silencers. This resource represents the first attempt at a comprehensive annotation of cis-regulatory elements in a metazoan genome.

    Harnessing information from whole genome sequencing in 185 individuals, this study generates a high-resolution map of copy number variants. Nucleotide resolution of the map facilitates analysis of structural variant distribution and identification of the mechanisms of their origin. The study provides a resource for sequence-based association studies.

    Birds and mammals have distinct sex chromosomes: in birds, males are ZZ and females ZW; in mammals, males are XY and females XX. By sequencing the chicken Z chromosome and comparing it with the human X chromosome, these authors overturn the currently held view that these chromosomes have diverged little from their autosomal progenitors. The Z and X chromosomes seem to have followed convergent evolutionary trajectories, despite evolving with opposite systems of heterogamety.
