    The evolution of adhesiveness as a social adaptation

    Thomas Garcia et al.
    Mathematical modeling supports a scenario where cell-cell adhesion gradually evolves through natural selection, leading to the emergence of cohesive aggregates in microbial populations.

    Cognitive regulation alters social and dietary choice by changing attribute representations in domain-general and domain-specific brain circuits

    Anita Tusche, Cendri A Hutcherson
    Regulatory success operates by goal-consistent increases and decreases of distinct attribute representations in generic neural hubs and in domain-specific brain regions, explaining when and why regulatory success generalizes across domains and contexts.

    A causal role for right temporo-parietal junction in signaling moral conflict

    Ignacio Obeso et al.
    Disrupting the right temporo-parietal junction did not change the general motivation to give or adapt behavior to social reputation cues, but specifically reduced the impact of moral-material conflict.

    Shearing in flow environment promotes evolution of social behavior in microbial populations

    Gurdip Uppal, Dervis Can Vural
    Shearing in fluid flow induces or enhances budding dispersal in microbial populations, resulting in stronger cooperative behavior.

    Evolution of empathetic moral evaluation

    Arunas L Radzvilavicius et al.
    Empathy can evolve and foster cooperation in a game-theoretic analysis of behavior.

    Point of View: Towards a mechanistic foundation of evolutionary theory

    Michael Doebeli et al.
    A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.

    Topological constraints in early multicellularity favor reproductive division of labor

    David Yanni et al.
    Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.

    Nucleolar dynamics and interactions with nucleoplasm in living cells

    Christina M Caragine et al.
    The nucleoplasm surrounding nucleoli in living cells plays a key role in nucleolar dynamics and shape fluctuations in vivo.

    Molecular function limits divergent protein evolution on planetary timescales

    Mariam M Konaté et al.
    Orthologous proteins that continuously maintain the same molecular function do not usually diverge beyond a certain level of sequence and structural similarity.
