    Maturation of a central brain flight circuit in Drosophila requires Fz2/Ca2+ signaling

    Tarjani Agrawal, Gaiti Hasan
    Gene knockdown experiments in fruit fly pupae reveal the role of the signaling molecule 'dFrizzled2' in the development of a neural circuit that helps insects to fly continuously for extended periods.

    A size principle for recruitment of Drosophila leg motor neurons

    Anthony W Azevedo et al.
    Motor neurons controlling the leg of the fruit fly exhibit a gradient of physiological and functional properties that correlate with the order in which they fire during behavior.

    Hedgehog signaling via Gli2 prevents obesity induced by high-fat diet in adult mice

    Yu Shi, Fanxin Long
    Targeted activation of Hedgehog signalling via Gli2 facilitated the reduction of high-fat-diet-induced obesity and improvement of whole-body glucose tolerance and insulin sensitivity in adult mice.

    Distinct ipRGC subpopulations mediate light’s acute and circadian effects on body temperature and sleep

    Alan C Rupp et al.
    Daily fluctuations versus transient perturbations in environmental light influence behavior and physiology through distinct circuits.

    Light-induced depigmentation in planarians models the pathophysiology of acute porphyrias

    Bradford M Stubenhaus et al.
    Physiological porphyrin biosynthesis causes photosensitivity in fasted planarians, providing an experimentally tractable animal model of acute porphyrias.

    The cation channel TRPA1 tunes mosquito thermotaxis to host temperatures

    Román A Corfas, Leslie B Vosshall
    Female mosquitoes are exquisitely sensitive to human body heat, and the TRPA1 gene is required to focus their attraction toward thermal stimuli resembling warm-blooded hosts.

    A primal role for the vestibular sense in the development of coordinated locomotion

    David E Ehrlich, David Schoppik
    Zebrafish use their sense of gravity and their cerebellum to coordinate the fin and body movements that, as they develop, allow them to better maintain balance as they climb.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann et al.
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

    Quantitative uniqueness of human brain evolution revealed through phylogenetic comparative analysis

    Ian F Miller et al.
    The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.

    A fitness trade-off between seasons causes multigenerational cycles in phenotype and population size

    Gustavo S Betini et al.
    Seasonal variation in resources causes opposing episodes of selection on body size, which interact with density dependence to influence population dynamics.
