    Myogenin controls via AKAP6 non-centrosomal microtubule-organizing center formation at the nuclear envelope

    Robert Becker et al.
    Myogenin promotes centrosome attenuation and establishes the nuclear envelope as the dominant microtubule organization center via the scaffold protein AKAP6, which is required for the recruitment of centrosomal proteins.

    The cooperative binding of TDP-43 to GU-rich RNA repeats antagonizes TDP-43 aggregation

    Juan Carlos Rengifo-Gonzalez et al.
    The RNA-mediated higher order assembly of TDP-43, a protein associated with neurodegenerative diseases, preserves its solubility by reducing the risk of multivalent interactions between low complexity domains.

    Evolutionary dynamics of circular RNAs in primates

    Gabriela Santos-Rodriguez et al.
    An analysis of the genomic features that distinguish conserved from species-specific circular RNAs reveals that the expansion of the downstream intron by insertion of retrotransposons stabilizes circular RNAs' production across 30+ millions years of evolution.

    Circular RNA repertoires are associated with evolutionarily young transposable elements

    Franziska Gruhl et al.
    Evolutionary analyses suggest that most mammalian circRNAs did not emerge from common ancestral circRNA precursors, arguing against widespread functional conservation.

    An XRCC4 mutant mouse, a model for human X4 syndrome, reveals interplays with Xlf, PAXX, and ATM in lymphoid development

    Benoit Roch et al.
    A viable separation of function XRCC4 knock-in mutant mouse model recapitulates some aspects of XRCC4 deficiency in humans, notably the absence of immune deficiency.

    The cell adhesion molecule Sdk1 shapes assembly of a retinal circuit that detects localized edges

    Pierre-Luc Rochon et al.
    A novel retinal ganglion cell requires a cell adhesion molecule to grow its dendrites, collect synaptic inputs, and become selective to edges placed in its receptive field.

    ASIC1a is required for neuronal activation via low-intensity ultrasound stimulation in mouse brain

    Jormay Lim et al.
    Mouse brain neurons response to transcranial ultrasound at the energy level of 5 mW/cm2 and repeated stimulations lead to neurogenesis while ASIC1a is required both in vitro and in vivo as one of the mechanoreceptors.

    Optimal plasticity for memory maintenance during ongoing synaptic change

    Dhruva V Raman, Timothy O'Leary
    Simple mathematical reasoning shows that the large amount of synaptic turnover seen in many parts of the brain is in fact optimal for memory retention.

    A projectome of the bumblebee central complex

    Marcel Ethan Sayre et al.
    Serial-section electron microscopy uncovers the intricate neural network of the bumblebee central complex, revealing highly conserved projection patterns as well as novel circuit elements potentially unique to bees.
