    Slightly beneficial genes are retained by bacteria evolving DNA uptake despite selfish elements

    Bram van Dijk et al.
    Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.

    Capturing the temporal evolution of choice across prefrontal cortex

    Laurence T Hunt et al.
    Experiments in macaques and humans reveal time-varying changes in prefrontal cortex activity that occur during decisions based on costs and benefits.

    Variable opportunities for outcrossing result in hotspots of novel genetic variation in a pathogen metapopulation

    Anna-Liisa Laine et al.
    In natural pathogen populations opportunities for sexual outcrossing vary, leading to spatial variation in genetic diversity and between-season survival.

    Whole genome comparison of a large collection of mycobacteriophages reveals a continuum of phage genetic diversity

    Welkin H Pope et al.
    A continuum of genome relationships is discovered through comparative genomics of 627 sequenced mycobacteriophages isolated and characterized in an integrated research/education initiative.

    Migration confers winter survival benefits in a partially migratory songbird

    Daniel Zúñiga et al.
    Testing of fitness-related benefits in migratory population of European blackbirds offers confirming predictions of theoretical models on the evolution and maintenance of migration.

    A specific role for serotonin in overcoming effort cost

    Florent Meyniel et al.
    A selective reuptake inhibitor shows a beneficial effect in healthy humans during an effort-benefit tradeoff task, mediated at the computational level by a specific alleviation of effort cost.

    Trading mental effort for confidence in the metacognitive control of value-based decision-making

    Douglas G Lee, Jean Daunizeau
    Intra-individual variability in choice, response time, subjective effort, confidence, and choice-induced preference change and certainty gain is explained by a cost–benefit model of cognitive resource allocation.

    Can Hamilton’s rule be violated?

    Matthijs van Veelen
    Hamilton's rule can be violated when costs and benefits of cooperation are defined using the counterfactual method, and when they depend on the cooperation of others.

    A mobile genetic element increases bacterial host fitness by manipulating development

    Joshua M Jones et al.
    A mobile genetic element provides a selective advantage to host cells by delaying development, including biofilm and spore formation, thereby enabling temporary cheating and extra divisions.
