    Transition to siblinghood causes a substantial and long-lasting increase in urinary cortisol levels in wild bonobos

    Verena Behringer, Andreas Berghänel ... Gottfried Hohmann
    In wild bonobos, sibling birth induced a sudden increase in urinary cortisol levels in the older offspring, a physiological response that occurred in all subjects and was independent of their age.

    Neighboring communities of bonobos hunt different prey species

    Social Learning: Does culture shape hunting behavior in bonobos?

    Andrew Whiten
    New evidence that neighboring communities of bonobos hunt different prey species, despite extensive overlaps in where they live and hunt, is difficult to explain without invoking cultural factors.

    Modelling the climatic suitability of Chagas disease vectors on a global scale

    Fanny E Eberhard, Sarah Cunze ... Sven Klimpel
    The global ensemble forecasting niche modelling of 11 vector competent triatomine species revealed climatic suitable regions outside their native distribution including the cosmopolitan vector Triatoma rubrofasciata.

    Postprandial sleep mechanics in Drosophila

    Keith R Murphy, Sonali A Deshpande ... William W Ja
    Evidence of food coma has been found in fruit flies, allowing the properties that drive postprandial sleep and their underlying genetic and neuronal mechanisms to be described.

    Multi-scale mapping along the auditory hierarchy using high-resolution functional UltraSound in the awake ferret

    Célian Bimbard, Charlie Demene ... Yves Boubenec
    Functional UltraSound imaging allows mapping tonotopic organisation in multiple auditory subcortical and cortical brain structures with an unprecedented spatial functional resolution, while giving access to long-distance top-down connectivity pattern from frontal cortex to auditory cortex.

    Pan-cortical 2-photon mesoscopic imaging and neurobehavioral alignment in awake, behaving mice

    Evan D Vickers, David A McCormick
    Procedures were developed to perform mesoscale 2-photon Ca2+ imaging simultaneously from all of mouse dorsolateral neocortex, facilitating identification of widespread neural ensembles with activity related to diverse aspects of behavior.

    Inhibition by small-molecule ligands of formation of amyloid fibrils of an immunoglobulin light chain variable domain

    Boris Brumshtein, Shannon R Esswein ... David S Eisenberg
    Ligands that bind dimers of light chain variable domains inhibit the formation of amyloid fibrils.

    Behavioural diversity of bonobo prey preference as a potential cultural trait

    Liran Samuni, Franziska Wegdell, Martin Surbeck
    Bonobo groups that share overlapping ranging areas and engage in regular social exchange show "behavioural group identity" of hunting techniques in the absence of local ecological variation.

    Characterization of the finch embryo supports evolutionary conservation of the naive stage of development in amniotes

    Siu-Shan Mak, Cantas Alev ... Raj K Ladher
    Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.

    Evidence for adolescent length growth spurts in bonobos and other primates highlights the importance of scaling laws

    Andreas Berghaenel, Jeroen MG Stevens ... Verena Behringer
    Scaling laws reveal the presence of adolescent growth spurts in bonobos and potentially in other non-human primates, challenging the notion of these spurts as a uniquely human trait and emphasizing the need to consider scaling laws when interpreting growth patterns.
