    Neural network of social interaction observation in marmosets

    Justine C Cléry, Yuki Hori ... Stefan Everling
    The brain network associated with social interaction observation involves large part of the frontal cortex and parietal areas in marmosets.

    Experimental evidence for delayed post-conflict management behaviour in wild dwarf mongooses

    Amy Morris-Drake, Julie M Kern, Andrew N Radford
    After experimentally simulated within-group conflict, dwarf mongoose bystanders engage in post-conflict management behaviour with a temporal delay.

    Aging: The temporary cost of dominance

    Calen P Ryan, Christopher W Kuzawa
    In a population of wild baboons, a new way to assess biological age reveals a surprising effect of social hierarchy.

    Vocalization–whisking coordination and multisensory integration of social signals in rat auditory cortex

    Rajnish P Rao, Falk Mielke ... Michael Brecht
    Snout-to-snout contact modulates the response of rat auditory cortex to calls from other animals, indicating that the multisensory nature of social interaction is directly represented in the rat brain.

    Higher social tolerance is associated with more complex facial behavior in macaques

    Alan V Rincon, Bridget M Waller ... Jérôme Micheletta
    Detailed quantification of macaque facial behavior reveals a positive link between social and communicative complexity, and helps us to better understand the evolution of animal communication.

    Mountain gorillas maintain strong affiliative biases for maternal siblings despite high male reproductive skew and extensive exposure to paternal kin

    Nicholas M Grebe, Jean Paul Hirwa ... Stacy Rosenbaum
    Mountain gorillas, who live in close-knit social groups with siblings and non-siblings of both sexes throughout their lives, show distinct behavioral biases towards maternal versus paternal kin.

    Rodent ultrasonic vocal interaction resolved with millimeter precision using hybrid beamforming

    Max L Sterling, Ruben Teunisse, Bernhard Englitz
    The accuracy of the Hybrid Vocalization Localizer (HyVL) brings a revolution to the study of social vocalizations of rodents and other animals, where vocalizations often occur in close proximity, and will empower downstream analysis of sequence and semantic analyses.

    Kin discrimination in social yeast is mediated by cell surface receptors of the Flo11 adhesin family

    Stefan Brückner, Rajib Schubert ... Hans-Ulrich Mösch
    Structural, biophysical and physiological analysis reveals how yeast cell surface adhesins evolved to confer self-nonself discrimination in single cells and whole populations.

    Social-affective features drive human representations of observed actions

    Diana C Dima, Tyler M Tomita ... Leyla Isik
    Social-affective features predict the perceived similarity of real-world actions better than, and independently of, visual and action-related features, and are extracted at the final stage of a temporal gradient in the brain.
