    Stochastic parabolic growth promotes coexistence and a relaxed error threshold in RNA-like replicator populations

    Mátyás Paczkó, Eörs Szathmáry, András Szilágyi
    An individual-based model framework of sub-exponentially growing replicator systems suggests that parabolic dynamics could have been able to maintain genetic diversity and circumvent the error threshold problem during early evolution.

    KIS counteracts PTBP2 and regulates alternative exon usage in neurons

    Marcos Moreno-Aguilera, Alba M Neher ... Carme Gallego
    KIS, a kinase upregulated in the developmental brain, phosphorylates the PTBP2 splicing complex and modulates alternative exon usage for proper synaptic spine emergence and maturation.

    Disease modeling and pharmacological rescue of autosomal dominant retinitis pigmentosa associated with RHO copy number variation

    Sangeetha Kandoi, Cassandra Martinez ... Deepak A Lamba
    Stem cell-derived retinal organoids are a useful tool to understand the pathobiology of devastating retinal degenerations and can aid to identify and validate therapeutics to promote rescue.

    Intra- and interspecific diversity in a tropical plant clade alter herbivory and ecosystem resilience

    Ari Grele, Tara J Massad ... Lora A Richards
    Experimental Piper gardens across five neotropical sites reveal complex contingencies in the influence of species and population-level biodiversity on the flow of resources to insect herbivores and ecosystem resilience to changes in water availability.

    Distinct transcriptomic profile of satellite cells contributes to preservation of neuromuscular junctions in extraocular muscles of ALS mice

    Ang Li, Jianxun Yi ... Jingsong Zhou
    The distinct transcriptomic features of extraocular muscle satellite cells, partially mimicked by NaBu treatment, endow enhanced self-renewal and axon attraction, contribute to neuromuscular junction preservation during ALS progression.

    Deletion of FNDC5/irisin modifies murine osteocyte function in a sex-specific manner

    Anika Shimonty, Fabrizio Pin ... Lynda F Bonewald
    Analysis of mice lacking the precursor for irisin, FNDC5, provides evidence for a sex-specific role of irisin in calcium release from bone due to osteocytic osteolysis.

    Episodic long-term memory formation during slow-wave sleep

    Flavio J Schmidig, Simon Ruch, Katharina Henke
    Sleep-encoded vocabulary influences awake decision-making 36 hr later, particularly when targeting the vocabulary to slow-wave troughs, which suggests that unconscious episodic memory formation during deep sleep is possible.

    Tgif1-deficiency impairs cytoskeletal architecture in osteoblasts by activating PAK3 signaling

    Simona Bolamperti, Hiroaki Saito ... Hanna Taipaleenmäki
    A novel mechanism underlying the regulation of osteoblast morphology, adherence, and migration that has implications in bone remodeling, regeneration, and response to the pharmacological effects of PTH treatment.

    Molecular mechanism of complement inhibition by the trypanosome receptor ISG65

    Alexander D Cook, Mark Carrington, Matthew K Higgins
    A structure derived from cryogenic electron microscopy shows how ISG65, an African trypanosome receptor that aids virulence, binds C3b and suggests mechanisms through which ISG65 might aid complement resistance.

    Chronic intermittent hypoxia reveals role of the Postinspiratory Complex in the mediation of normal swallow production

    Alyssa D Huff, Marlusa Karlen-Amarante ... Jan-Marino Ramirez
    Glutamatergic–cholinergic neurons in the postinspiratory complex are critical for swallow motor patterning and the coordination of swallow and breathing, which is disrupted by chronic intermittent hypoxia, a condition seen in many disorders associated with dysphagia and aspiration pneumonia.
