    Sex-specific effects of cooperative breeding and colonial nesting on prosociality in corvids

    Lisa Horn et al.
    A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.

    Clusters of cooperative ion channels enable a membrane-potential-based mechanism for short-term memory

    Paul Pfeiffer et al.
    Independently gating ion channels typically act fast within milliseconds, but cooperative interactions within a cluster of channels allow for a memory of previous electrical activity for several seconds.

    A panel of induced pluripotent stem cells from chimpanzees: a resource for comparative functional genomics

    Irene Gallego Romero et al.
    A panel of chimpanzee induced pluripotent stem cells (iPSCs) will help realise the potential of iPSCs in primate studies, and in combination with genomic technologies, transform studies of comparative evolution.

    Pleiotropic mutations can rapidly evolve to directly benefit self and cooperative partner despite unfavorable conditions

    Samuel Frederick Mock Hart et al.
    Mutations that directly benefit both self and cooperative partner can readily evolve to promote cooperation.

    Expanding the MECP2 network using comparative genomics reveals potential therapeutic targets for Rett syndrome

    Irene Unterman et al.
    A novel comparative genomics framework identifies MECP2 network proteins targeted by existing drugs, with three drugs validated in an in vitro Rett syndrome model.

    Quantitative uniqueness of human brain evolution revealed through phylogenetic comparative analysis

    Ian F Miller et al.
    The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.

    Comparative genomics explains the evolutionary success of reef-forming corals

    Debashish Bhattacharya et al.
    The analysis of 20 coral genomic datasets provides unprecedented insights into what makes reef-building corals unique, including the evolution of novel gene families involved in biomineralization, signaling and stress responses that have led to their evolutionary success throughout the Phanerozoic Eon.

    High-quality carnivoran genomes from roadkill samples enable comparative species delineation in aardwolf and bat-eared fox

    Rémi Allio et al.
    High-quality genomes can be obtained from roadkill samples and used in population genomics for species delimitation with conservation implications.

    Cofilin-induced unidirectional cooperative conformational changes in actin filaments revealed by high-speed atomic force microscopy

    Kien Xuan Ngo et al.
    A cluster of cofilin along an otherwise bare actin filament induces distinctively asymmetric cooperative conformational changes to the filament on either side of the cluster.

    Whole brain comparative anatomy using connectivity blueprints

    Rogier B Mars et al.
    White matter connectivity assessed using diffusion MRI allows one to compare whole-brain organization between different animal species in a quantitative fashion, identifying homologous areas and regions of unique specialization.
