    Constraints on neural redundancy

    Jay A Hennig et al.
    The distribution of redundant neural activity is coupled with task-relevant activity, which may limit the extent to which redundancy can be exploited by the brain for computation.

    How competition governs whether moderate or aggressive treatment minimizes antibiotic resistance

    Caroline Colijn, Ted Cohen
    Both within and between hosts, the key factor guiding whether increasing treatment strength will increase or decrease antibiotic resistance is whether inter-strain competition is effective, not whether it is present.

    Unfair competition governs the interaction of pCPI-17 with myosin phosphatase (PP1-MYPT1)

    Joshua J Filter et al.
    Unfair competition, in which a phosphatase and a phosphoprotein inhibitor/substrate mutually sequester each other from competing substrates and enzymes, is a conserved mechanism for the control of PPP family phosphatases.

    Roles of C/EBP class bZip proteins in the growth and cell competition of Rp (‘Minute’) mutants in Drosophila

    Jorge Blanco et al.
    Xrp1 contributes to cell competition as a heterodimer with the Drosophila C/EBP homolog Irbp18 and although rapidly evolving is itself conserved beyond Drosophila.

    Competition between histone and transcription factor binding regulates the onset of transcription in zebrafish embryos

    Shai R Joseph et al.
    The relative levels of histones and transcription factors in the nucleus determine transcriptional output in zebrafish embryos.

    Multistability and regime shifts in microbial communities explained by competition for essential nutrients

    Veronika Dubinkina et al.
    Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.

    Genetic architecture of natural variation in cuticular hydrocarbon composition in Drosophila melanogaster

    Lauren M Dembeck et al.
    Genome wide association analyses in a wild-derived Drosophila melanogaster population uncover extensive variation in cuticular hydrocarbon composition, which may present a target for natural selection and adaptive evolution.

    A quantitative inventory of yeast P body proteins reveals principles of composition and specificity

    Wenmin Xing et al.
    Quantitative analyses of yeast P bodies reveals a small number of highly concentrated proteins and many weakly concentrated proteins, suggesting that the compartments are compositionally simpler than previously thought.

    Trade-off shapes diversity in eco-evolutionary dynamics

    Farnoush Farahpour et al.
    In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.

    Response repetition biases in human perceptual decisions are explained by activity decay in competitive attractor models

    James J Bonaiuto et al.
    Residual activity from previous trials in a biophysical decision network model causes biases in choice behavior such that a previous response is more likely to be repeated.
