    Correlated evolution between repertoire size and song plasticity predicts that sexual selection on song promotes open-ended learning

    Cristina M Robinson et al.
    A longer birdsong-learning window evolves in response to sexual selection for song complexity and is associated with faster evolution of song performance characteristics.

    Indirect sexual selection drives rapid sperm protein evolution in abalone

    Damien Beau Wilburn et al.
    An NMR-based structural study of sperm proteins reveals a novel protein packaging/dispersion system embedded in a coevolutionary arms race.

    Sexual selection gradients change over time in a simultaneous hermaphrodite

    Jeroen NA Hoffer et al.
    The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

    A suppression hierarchy among competing motor programs drives sequential grooming in Drosophila

    Andrew M Seeds et al.
    Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.

    COMP-1 promotes competitive advantage of nematode sperm

    Jody M Hansen et al.
    Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.

    Mitochondrial support of persistent presynaptic vesicle mobilization with age-dependent synaptic growth after LTP

    Heather L Smith et al.
    Three-dimensional electron microscopy (3DEM) demonstrates the dependence on presynaptic mitochondria for vesicle mobilization as dendritic spines are silently added at P15 or synapses are silently enlarged in adults after long-term potentiation.

    High-quality ultrastructural preservation using cryofixation for 3D electron microscopy of genetically labeled tissues

    Tin Ki Tsang et al.
    A broadly applicable method that faithfully preserves genetically labeled cellular structures for 3D electron microscopy (EM) and correlated light and electron microscopy (CLEM).

    A biological switching valve evolved in the female of a sex-role reversed cave insect to receive multiple seminal packages

    Kazunori Yoshizawa et al.
    The discovery of a biological switching valve provides an example of a mechanism that evolved in nature long before its invention by man and could inspire alternative valve technologies.
