    Newly discovered and conserved role of IgM against viral infection in an early vertebrate

    Weiguang Kong, Xinyou Wang ... Zhen Xu
    sIgM plays a role in viral neutralization across both primitive and modern vertebrates by following conserved principles in the development of specialized antiviral immunity.

    Deletion of sulfate transporter SUL1 extends yeast replicative lifespan via reduced PKA signaling instead of decreased sulfate uptake

    Juan Long, Meng Ma ... Jing Yang
    SUL1 deletion extends lifespan via PKA-MSN2 pathways, underscoring nutrient signaling over sulfate transport in aging regulation.

    DNA methylation insulates genic regions from CTCF loops near nuclear speckles

    Shelby A Roseman, Allison P Siegenfeld ... Brian B Liau
    CTCF binding promotes chromatin-nuclear speckle interactions and gene activation after DNA demethylation, yet its binding and looping patterns are unaffected by speckle depletion.

    WRN and WRNIP1 ATPases impose high fidelity on translesion synthesis by Y-family DNA polymerases

    Jung Hoon Yoon, Karthi Sellamuthu ... Satya Prakash
    WRN and WRNP1 ATPases together with WRN 3’ to 5’ exonuclease raise the fidelity of intrinsically highly error-prone Y-family DNA polymerases such that they perform error-free translesion synthesis.

    The Product neutrality function defining genetic interactions emerges from mechanistic models of cell growth

    Lucas Fuentes Valenzuela, Paul Francois, Jan M Skotheim
    Coarse-grained models of cellular growth and high-throughput empirical genetic data support the Product neutrality function in which a double-mutant fitness is the product of single-mutant fitnesses.

    Opening and closing of a cryptic pocket in VP35 toggles it between two different RNA-binding modes

    Upasana L Mallimadugula, Matthew A Cruz ... Gregory R Bowman
    The cryptic pocket is critical for one of the VP35 protein's functions and therefore is likely under selective pressure.

    Gene expression variation across genetically identical individuals predicts reproductive traits

    Amy K Webster, John H Willis ... Patrick C Phillips
    Differences among genetically identical individuals can be explained using expression levels of just a handful of genes, suggesting that environmental variation can be functionally analyzed.

    Coral anthozoan-specific opsins employ a novel chloride counterion for spectral tuning

    Yusuke Sakai, Saumik Sen ... Akihisa Terakita
    Environmental chloride ions act as essential counterions that enable coral opsins to respond to visible light, and the polar residue Glu292 plays a critical role in chloride binding.

    Development of D-box peptides to inhibit the anaphase-promoting complex/cyclosome

    Rohan Eapen, Cynthia Okoye ... Laura S Itzhaki
    Peptide inhibitors of E3 ubiquitin ligase anaphase-promoting complex/cyclosome, engineered for enhanced affinity by incorporating unnatural amino acids, are able to block substrate ubiquitination and drive degradation of a fused target.

    Evidence for deliberate burial of the dead by Homo naledi

    Lee R Berger, Tebogo Vincent Makhubela ... John Hawks
    Remains of the extinct hominin species Homo naledi were interred by members of their own species, the first time that burial has been documented in populations other than modern humans and Neanderthals.
