    mPFC spindle cycles organize sparse thalamic activation and recently active CA1 cells during non-REM sleep

    Carmen Varela, Matthew A Wilson
    Sleep spindles provide a temporal framework to organize the reactivation of behaviorally relevant CA1 cells and sparsely active cells in the limbic thalamus.

    Doa10 is a membrane protein retrotranslocase in ER-associated protein degradation

    Claudia C Schmidt, Vedran Vasic, Alexander Stein
    Doa10, a membrane-embedded ubiquitin ligase, facilitates the removal of membrane proteins from the endoplasmic reticulum and cooperates with the Cdc48 ATPase in this process.

    Slightly beneficial genes are retained by bacteria evolving DNA uptake despite selfish elements

    Bram van Dijk, Paulien Hogeweg ... Nobuto Takeuchi
    Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.

    Leptin increases sympathetic nerve activity via induction of its own receptor in the paraventricular nucleus

    Zhigang Shi, Nicole E Pelletier ... Virginia L Brooks
    Leptin acts in the paraventricular nucleus to slowly increase sympathetic nerve activity to skeletal muscle and brown adipose tissue via induction of its own receptor in TRH glutamatergic neurons.

    Self-restoration of cardiac excitation rhythm by anti-arrhythmic ion channel gating

    Rupamanjari Majumder, Tim De Coster ... Daniël A Pijnappels
    Customization of ion channel gating enhances homeostatic regulation through automatic detection and correction of abnormal physiological changes, as illustrated by self-restoration of excitation rhythm in cardiac arrhythmias.

    Cohesin and condensin extrude DNA loops in a cell cycle-dependent manner

    Stefan Golfier, Thomas Quail ... Jan Brugués
    Reconstitution of DNA loop extrusion in cellular contexts using Xenopus egg extracts shows that condensin extrudes DNA loops non-symmetrically in metaphase, whereas cohesin extrudes DNA loops symmetrically in interphase.

    Identification of a novel toxicophore in anti-cancer chemotherapeutics that targets mitochondrial respiratory complex I

    Zoe A Stephenson, Robert F Harvey ... Anne E Willis
    A novel toxicophore, a 1H-1,2,3-triazole, has been identified in a wide-number of therapeutically-relevant compounds, including two anti-cancer chemotherapeutics, which inhibits mitochondria function and is mechanistically linked to adverse cardiac-cell events.

    Specific labeling of synaptic schwann cells reveals unique cellular and molecular features

    Ryan Castro, Thomas Taetzsch ... Gregorio Valdez
    The discovery of markers specific to perisynaptic Schwann cells will accelerate the discovery of mechanisms important for their differentiation and function.

    Numerical magnitude, rather than individual bias, explains spatial numerical association in newborn chicks

    Rosa Rugani, Giorgio Vallortigara ... Lucia Regolin
    Spatial numerical association in three-day-old domestic chicks linearly decreases as numerical magnitude increases (2>5>8), supporting the hypothesis that numerical magnitude guides the spatial numerical association.

    Controlling motor neurons of every muscle for fly proboscis reaching

    Claire E McKellar, Igor Siwanowicz ... Julie H Simpson
    A new collection of fly strains comprehensively targets the motor neurons of the proboscis, allowing separate control of every muscle to determine how this appendage achieves flexible, directed reaching.
