    Plasticity and evolutionary convergence in the locomotor skeleton of Greater Antillean Anolis lizards

    Nathalie Feiner et al.
    A comparative and experimental research refutes the controversial hypothesis that plasticity played a major role in the convergent evolution of Anolis ecomorphs.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    Nutrient status shapes selfish mitochondrial genome dynamics across different levels of selection

    Bryan L Gitschlag et al.
    Food supply and nutrient stress tolerance coordinately shape the multilevel selection dynamics of a mitochondrial cheater by promoting cheater persistence at both within-host and between-host levels of selection.

    Empathic pain evoked by sensory and emotional-communicative cues share common and process-specific neural representations

    Feng Zhou et al.
    Machine learning analyses reveal that the observation of acute pain inflictions and facial expressions of pain evoke shared pain-specific neural representations.

    Poultry farmer response to disease outbreaks in smallholder farming systems in southern Vietnam

    Alexis Delabouglise et al.
    Longitudinal monitoring of poultry farms in southern Vietnam reveals that when outbreaks occur with symptoms similar to highly pathogenic avian influenza, farmers respond by sending their chickens to market early.

    Inherent regulatory asymmetry emanating from network architecture in a prevalent autoregulatory motif

    Md Zulfikar Ali et al.
    Network architecture and physiological features of the cell dictate asymmetric gene regulation between a negative autoregulatory TF gene and its target gene.

    Genetic mapping of etiologic brain cell types for obesity

    Pascal N Timshel et al.
    Unbiased computational integration of single-cell- and human genetics data shows that susceptibility to obesity is driven by a broad set of neuronal populations across the brain.

    Genome-wide alterations of uracil distribution patterns in human DNA upon chemotherapeutic treatments

    Hajnalka L Pálinkás et al.
    Human genomic DNA contains uracil in the late replicating, constitutive heterochromatic regions, while treatment with drugs perturbing thymidylate biosynthesis shifts the uracil distribution pattern towards the euchromatin in UNG-inhibited cells.

    Growth-factor-mediated coupling between lineage size and cell fate choice underlies robustness of mammalian development

    Néstor Saiz et al.
    A mechanistic basis is provided for the regulative ability of the mammalian embryo offering a long-sought explanation for coordinating cell behaviors at the population level ensuring robustness in developmental outcome.

    The Mla pathway in Acinetobacter baumannii has no demonstrable role in anterograde lipid transport

    Matthew J Powers et al.
    An outer membrane vesicle pulse-chase assay demonstrates that the Acinetobacter baumannii Mla system is a retrograde lipid transporter.
