    In vivo imaging of β-cell function reveals glucose-mediated heterogeneity of β-cell functional development

    Jia Zhao et al.
    In vivo imaging reveals that gradually increased amount of glucose mediates the heterogeneous functional development of individual β-cells by activating its major downstream calcineurin/NFAT signaling pathway.

    Human gut Bacteroides capture vitamin B12 via cell surface-exposed lipoproteins

    Aaron G Wexler et al.
    The human gut bacterial lipoprotein BtuG binds vitamin B12 with femtomolar affinity, can remove vitamin B12 from human intrinsic factor, and is required for commensal fitness in the gut.

    Reconstructing the functions of endosymbiotic Mollicutes in fungus-growing ants

    Panagiotis Sapountzis et al.
    Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.

    Hawkmoths evaluate scenting flowers with the tip of their proboscis

    Alexander Haverkamp et al.
    Building on previous work (Kessler et al., 2015), it is shown that long-tongued hawkmoths assess individual flowers by smelling floral odors with olfactory neurons on their proboscises, and that this close-range perception is crucial for successful pollination and foraging.
