    A century of trends in adult human height

    NCD Risk Factor Collaboration (NCD-RisC)
    Height in early adulthood is an indicator that integrates across different dimensions of sustainable human development with links to health and longevity, nutrition, education and economic productivity.

    Mechanistic target of rapamycin (mTOR) pathway in Sertoli cells regulates age-dependent changes in sperm DNA methylation

    Saira Amir, Olatunbosun Arowolo ... Alexander Suvorov
    For the first time, a molecular mechanism is identified, for experimental acceleration and deceleration (rejuvenation) of sperm epigenetic aging.

    Tissue-specific mitochondrial HIGD1C promotes oxygen sensitivity in carotid body chemoreceptors

    Alba Timón-Gómez, Alexandra L Scharr ... Andy J Chang
    An atypical configuration of mitochondrial electron transport chain proteins may underlie the exquisite sensitivity of the carotid body to small decreases in oxygen availability.

    Obesity-linked suppression of membrane-bound O-acyltransferase 7 (MBOAT7) drives non-alcoholic fatty liver disease

    Robert N Helsley, Venkateshwari Varadharajan ... J Mark Brown
    Loss of function of membrane-bound O-acyltransferase 7 (MBOAT7), but not transmembrane channel-like 4 (TMC4), promotes hepatic steatosis.

    Functional development of a V3/glycan-specific broadly neutralizing antibody isolated from a case of HIV superinfection

    Mackenzie M Shipley, Vidya Mangala Prasad ... Julie M Overbaugh
    A bnAb derived from a case of HIV superinfection has distinct qualities from other HIV-specific bnAbs, including framework residues that contribute to neutralization breadth and a unique viral escape profile.

    Microtubules originate asymmetrically at the somatic golgi and are guided via Kinesin2 to maintain polarity within neurons

    Amrita Mukherjee, Paul S Brooks ... Paul T Conduit
    The somatic Golgi acts as an asymmetric MTOC within Drosophila neurons, and this, together with the action Kinesin-2, helps maintain minus-end-out microtubule polarity with proximal dendrites.

    Efficient analysis of mammalian polysomes in cells and tissues using Ribo Mega-SEC

    Harunori Yoshikawa, Mark Larance ... Angus I Lamond
    Translationally active polysomes from mammalian cells/tissues are successfully separated with rapidity, high efficiency and exceptional reproducibility by a SEC-based approach, an accessible alternative to the conventional sucrose density gradient analysis.

    Regulation of pulmonary surfactant by the adhesion GPCR GPR116/ADGRF5 requires a tethered agonist-mediated activation mechanism

    James P Bridges, Caterina Safina ... Marie-Gabrielle Ludwig
    Mutagenesis and activity assays in vitro and in vivo identify residues in the tethered agonist of GPR116, as well as those within the extracellular loops, that are critical for mediating the response to the tethered agonist.

    Homeostatic control of an iron repressor in a GI tract resident

    Yuanyuan Wang, Yinhe Mao ... Changbin Chen
    Post-translational modifications of an iron-responsive regulator drive Candida albicans commensalism in gastrointestinal tract.

    Single molecule microscopy reveals key physical features of repair foci in living cells

    Judith Miné-Hattab, Mathias Heltberg ... Angela Taddei
    Upon DNA damage, Rad52 forms a membraneless sub-compartment where Rad52 molecules are highly dynamic and share properties with liquid-liquid phase-separated molecules, reflecting the existence of a liquid droplet around damaged DNA.
