    Long ascending propriospinal neurons provide flexible, context-specific control of interlimb coordination

    Amanda M Pocratsky, Courtney T Shepard ... David SK Magnuson
    Conditional silencing of long ascending propriospinal neurons disrupts interlimb coordination of the fore and hindlimb pairs, but in a highly context-specific manner.

    Scn1a-GFP transgenic mouse revealed Nav1.1 expression in neocortical pyramidal tract projection neurons

    Tetsushi Yamagata, Ikuo Ogiwara ... Kazuhiro Yamakawa
    In neocortex, Nav1.1 is expressed in neocortical pyramidal tract projection neurons and a minor subpopulation of cortico-cortical projection neurons in addition to its predominant expression in inhibitory neurons, while the majority of cortico-thalamic, cortico-striatal, and cortico-cortical neurons express Nav1.2.

    A new genus of horse from Pleistocene North America

    Peter D Heintzman, Grant D Zazula ... Beth Shapiro
    The extinct stilt-legged equids of North America are not related to Asiatic asses or horses, but instead represent a distinct lineage outside of living equid diversity that became extinct in the terminal Pleistocene.

    Caenorhabditis elegans PIEZO channel coordinates multiple reproductive tissues to govern ovulation

    Xiaofei Bai, Jeff Bouffard ... Andy Golden
    Depletion of the mechanosensitive ion channel PEZO-1 in C. elegans disrupts the sheath and spermathecae cells to disrupt oocyte ovulation, resulting in crushed oocytes.

    Autophagosome development and chloroplast segmentation occur synchronously for piecemeal degradation of chloroplasts

    Masanori Izumi, Sakuya Nakamura ... Shinya Hagihara
    A plant autophagy pathway transports chloroplast stroma and envelope components into the vacuole through the division and encapsulation of the site of chloroplasts that is associated with developing autophagosome.

    A remarkable adaptive paradigm of heart performance and protection emerges in response to marked cardiac-specific overexpression of ADCY8

    Kirill V Tarasov, Khalid Chakir ... Edward G Lakatta
    Overexpression of hAC8 engages complex, coordinate adaptation 'circuity' that has evolved in mammalian cells to defend against stress that threatens health or life, and may be important for proper healing in disease states such as heart infarction or failure.

    The molecular basis of coupling between poly(A)-tail length and translational efficiency

    Kehui Xiang, David P Bartel
    For poly(A)-tail length to influence mRNA translational efficiency, poly(A)-binding protein (PABPC) must be limiting, mRNAs lacking PABPC must be stable, and translation initiation must be sensitive to PABPC levels.

    Single-cell transcriptomes of developing and adult olfactory receptor neurons in Drosophila

    Colleen N McLaughlin, Maria Brbić ... Hongjie Li
    Single-cell transcriptomes of olfactory receptor neurons at multiple developmental stages reveal cell-type-specific gene expression programs that underlie their development and sensory biology.

    Epac2 in midbrain dopamine neurons contributes to cocaine reinforcement via enhancement of dopamine release

    Xiaojie Liu, Casey R Vickstrom ... Qing-song Liu
    The cAMP sensor and effector Epac2 facilitates dopamine release and promotes cocaine reward.
