    The ESCRT machinery regulates retromer-dependent transcytosis of septate junction components in Drosophila

    Hendrik Pannen et al.
    A novel role of endosomal machineries retromer and ESCRT in membrane delivery of Drosophila septate junction components is required for maintenance of junction integrity and epithelial barrier function.

    Microsecond interaural time difference discrimination restored by cochlear implants after neonatal deafness

    Nicole Rosskothen-Kuhl et al.
    Early deaf human CI users are often insensitive to sub-millisecond interaural time differences (ITDs); however, with synchronized CIs, early deafened rats learned to lateralize small ITDs near 50 µs.

    Proofreading through spatial gradients

    Vahe Galstyan et al.
    Theoretical study shows how enzymes can achieve substrate proofreading by taking advantage of existing molecular gradients in the cell while not being endowed with structural features typically required for proofreading.

    Amplitude modulations of cortical sensory responses in pulsatile evidence accumulation

    Sue Ann Koay et al.
    From as early as primary visual cortex and across posterior cortical areas, neural responses to visual pulses during an evidence-accumulation task exhibit a multitude of task-related amplitude modulations/gain changes.

    Bi-fated tendon-to-bone attachment cells are regulated by shared enhancers and KLF transcription factors

    Shiri Kult et al.
    The molecular identity of bi-fated tendon-to-bone attachment cells, which display a mixture of transcriptomes of two neighboring cell types, enables the formation of the unique transitional tissue of the enthesis.

    Evolutionary conflicts and adverse effects of antiviral factors

    Daniel Sauter, Frank Kirchhoff
    Innate antiviral factors do not always perfectly distinguish between self and foreign, and potential adverse effects of antiviral defense mechanisms for the host have been discussed.

    The orchestrated cellular and molecular responses of the kidney to endotoxin define a precise sepsis timeline

    Danielle Janosevic et al.
    Single-cell RNA-sequencing identifies the precise cellular and molecular events that occur along the sepsis timeline in the kidney, pointing to potential biomarkers and therapeutic targets.

    Emx2 regulates hair cell rearrangement but not positional identity within neuromasts

    Sho Ohta et al.
    Emx2 is not required for sibling HCs to acquire their designated locations within the neuromast, inferring that Emx2 mediates opposite HC orientation by changing location of hair bundle establishment.

    Ca2+ signaling driving pacemaker activity in submucosal interstitial cells of Cajal in the murine colon

    Salah A Baker et al.
    An optogenetic dual-color Ca2+-imaging approach shows how submucosal pacemaker-cells, interstitial cells of Cajal, modulate smooth-muscle responses and drive colonic motility via complex Ca2+ signaling.
