    Developmentally regulated H2Av buffering via dynamic sequestration to lipid droplets in Drosophila embryos

    Matthew Richard Johnson et al.
    In early Drosophila embryos, histone H2Av continuously exchanges between cytoplasmic lipid droplets, a process that modulates H2Av import into nuclei and constitutes a novel post-translational strategy to regulate nuclear H2Av levels.

    Output variability across animals and levels in a motor system

    Angela Wenning et al.
    Population output variability in a motor control system varies across levels (CPG, motor neurons, muscles) and can be ascribed to life history differences among animals and in some cases to differences between bilaterally homologous elements.

    Transcriptome analysis illuminates the nature of the intracellular interaction in a vertebrate-algal symbiosis

    John A Burns et al.
    The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.

    Epigenetic modification of the PD-1 (Pdcd1) promoter in effector CD4+ T cells tolerized by peptide immunotherapy

    Rhoanne C McPherson et al.
    Peptide immunotherapy in mice depends upon sustained expression of co-inhibitory protein PD-1 in T cells.

    Discovery and characterization of a prevalent human gut bacterial enzyme sufficient for the inactivation of a family of plant toxins

    Nitzan Koppel et al.
    A unique, widely distributed gut bacterial enzyme selectively metabolizes plant-derived cardiac glycoside drugs.

    Na+/K+ pump interacts with the h-current to control bursting activity in central pattern generator neurons of leeches

    Daniel Kueh et al.
    The dynamic current generated Na+/K+ pump interacts with the h-current to control the bursting activity of oscillator heart interneurons.

    A circuit mechanism for the propagation of waves of muscle contraction in Drosophila

    Akira Fushiki et al.
    Coordinated activation and deactivation of inhibitory neurons triggers sequential muscle contractions that enable fruit fly larvae to propel themselves backwards and forwards.

    Hidden synaptic differences in a neural circuit underlie differential behavioral susceptibility to a neural injury

    Akira Sakurai et al.
    Animal-to-animal variability in neural circuit elements is often hidden under normal conditions, but becomes functionally relevant when the system is challenged by injury.

    ketu mutant mice uncover an essential meiotic function for the ancient RNA helicase YTHDC2

    Devanshi Jain et al.
    The mouse gene Ythdc2 exemplifies an evolutionarily ancient family of crucial regulators of the transition from germline stem cell divisions to meiosis.
