    The evolution of non-reproductive workers in insect colonies with haplodiploid genetics

    Jason W Olejarz et al.
    A mathematical model predicts the precise conditions for natural selection to favor the evolution of non-reproductive workers in insect colonies with haplodiploid genetics.

    Genes associated with ant social behavior show distinct transcriptional and evolutionary patterns

    Alexander S Mikheyev, Timothy A Linksvayer
    Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.

    A Mesozoic clown beetle myrmecophile (Coleoptera: Histeridae)

    Yu-Lingzi Zhou et al.
    A 99-million year old beetle in amber was a myrmecophile—a social impostor of the earliest-known ant colonies—revealing the most ancient behavioral symbiosis yet discovered in the Metazoa.

    Social Psychology: A mathematical look at empathy

    Naoki Masuda, Francisco C Santos
    When an individual makes a judgement about the actions of another individual, taking the latter's viewpoint into consideration enhances cooperation in society at large.

    Point of View: Predictive regulation and human design

    Peter Sterling
    Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

    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.

    Philosophy of Biology: Seizing an opportunity

    Perry Zurn, Danielle S Bassett
    Historical texts offer researchers in neuroscience, philosophy and literature the opportunity to work together to explore mysteries of the mind and human behavior.

    Homeodomain protein Otp affects developmental neuropeptide switching in oxytocin neurons associated with a long-term effect on social behavior

    Einav Wircer et al.
    Experiments in zebrafish reveal a new role for a critical hypothalamic transcription factor, orthopedia, in controlling developmental neuropeptide balance in a discrete oxytocin-producing neuronal circuit whose disrupted development affects social behavior.

    The golden mimicry complex uses a wide spectrum of defence to deter a community of predators

    Stano Pekár et al.
    A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.
