    Disease consequences of higher adiposity uncoupled from its adverse metabolic effects using Mendelian randomisation

    Susan Martin, Jessica Tyrrell ... Hanieh Yaghootkar
    Using genetics, it is possible to uncouple higher adiposity from its adverse metabolic effects and show that some obesity-associated conditions may benefit from treating the metabolic effects alone, whilst others may benefit more from weight loss.

    The dynamic conformational landscape of the protein methyltransferase SETD8

    Shi Chen, Rafal P Wiewiora ... Minkui Luo
    Integrated experimental-computational approaches were implemented to reveal the dynamic conformational landscape of a biologically relevant protein methyltransferase SETD8 for functional annotation.

    Muscle systems and motility of early animals highlighted by cnidarians from the basal Cambrian

    Xing Wang, Jean Vannier ... Jian Han
    Exceptionally preserved small shelly fossils (SSFs) from the early Cambrian Kuanchuanpu Formation (535 million years ago) reveal the muscular system of ancient cnidarians.

    A TOPBP1 allele causing male infertility uncouples XY silencing dynamics from sex body formation

    Carolline Ascenção, Jennie R Sims ... Marcus B Smolka
    A Topbp1 mutant mouse reveals a non-canonical role for the ATR-TOPBP1 signaling axis in meiosis, separating ATR signaling and meiotic sex chromosome inactivation from sex body formation.

    Heterogeneity of the GFP fitness landscape and data-driven protein design

    Louisa Gonzalez Somermeyer, Aubin Fleiss ... Fyodor A Kondrashov
    Orthologous proteins display different mutational robustness that can be leveraged to improve prediction of functional sequences.

    Absolute quantitation of individual SARS-CoV-2 RNA molecules provides a new paradigm for infection dynamics and variant differences

    Jeffrey Y Lee, Peter AC Wing ... Ilan Davis
    Single-molecule analysis of SARS-CoV-2 RNA identifies significant heterogeneity in cellular viral RNA levels and highlights slower replication kinetics for the Alpha variant compared to the Victoria strain.

    IFNγ induces epigenetic programming of human T-bethi B cells and promotes TLR7/8 and IL-21 induced differentiation

    Esther Zumaquero, Sara L Stone ... Frances E Lund
    IFNγ increases the responsiveness of human B cells to IL-2, TLR7/8 and IL-21 signals and therefore enhances antibody production in inflammatory settings associated with autoimmune or chronic disease.

    Epidermal Growth Factor Receptor neddylation is regulated by a desmosomal-COP9 (Constitutive Photomorphogenesis 9) signalosome complex

    Nicole Ann Najor, Gillian Nicole Fitz ... Kathleen Janee Green
    A protein interaction screen revealed desmosomes as a scaffold for the COP9 de-neddylating complex, to promote epidermal differentiation by governing the balance of Nedd8 and Ubiquitin modifications on Epidermal Growth Factor Receptor.

    Acknowledging selection at sub-organismal levels resolves controversy on pro-cooperation mechanisms

    Wenying Shou
    Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

    Using light and X-ray scattering to untangle complex neuronal orientations and validate diffusion MRI

    Miriam Menzel, David Gräßel ... Marios Georgiadis
    Light and X-ray scattering on the same primate and human brain samples cross-validate each other and enable accurate mapping of axonal trajectories in regions with uni- and multi-directional nerve fibers, which can be used to validate diffusion MRI.
