    Rapid adaptation of endocytosis, exocytosis, and eisosomes after an acute increase in membrane tension in yeast cells

    Joël Lemière, Yuan Ren, Julien Berro
    Within minutes after an abrupt increase in membrane tension, yeast cells reduce their membrane tension by modulating their rate of endocytosis and exocytosis, and adapt their endocytic actin machinery.

    Neuronal origins of reduced accuracy and biases in economic choices under sequential offers

    Weikang Shi, Sebastien Ballesta, Camillo Padoa-Schioppa
    Neuronal activity in the primate orbitofrontal cortex reveals different choice biases observed when offers are presented sequentially originate at different stages of the decision process.

    Autoinhibition and regulation by phosphoinositides of ATP8B1, a human lipid flippase associated with intrahepatic cholestatic disorders

    Thibaud Dieudonné, Sara Abad Herrera ... Guillaume Lenoir
    Single particle cryo-electron microscopy associated with functional studies reveal a critical role of N- and C-terminal tails in the autoinhibition of the disease-related ATP8B1-CDC50A lipid flippase, the possible role of phosphorylation in autoinhibition relief, and strong activation by PI(3,4,5)P3.

    Drosulfakinin signaling modulates female sexual receptivity in Drosophila

    Tao Wang, Biyang Jing ... Chuan Zhou
    The neuropeptide Drosulfakinin (DSK) functions in a subset of DSK neurons to interact with neural nodes in the sex circuit and acts through its receptor CCKLR-17D3 to control female sexual behavior.

    Hippocampal-hypothalamic circuit controls context-dependent innate defensive responses

    Jee Yoon Bang, Julia Kathryn Sunstrum ... Junchul Kim
    The hippocampus controls context-dependent defensive behaviors through the anterior hypothalamus, a major component of the medial hypothalamic defense system, by retrieving contextual information essential for avoiding predatory threats and escaping to a safe shelter.

    Windborne migration amplifies insect-mediated pollination services

    Huiru Jia et al.
    Delineating Episyrphus balteatus transregional movements and pollination networks advance a deep understanding of its migration ecology and facilitate the design of targeted strategies to conserve and enhance its ecosystem services.

    Inhibitory proteins block substrate access by occupying the active site cleft of Bacillus subtilis intramembrane protease SpoIVFB

    Sandra Olenic, Lim Heo ... Lee Kroos
    A novel mechanism of intramembrane protease regulation involves a protein blocking the active site of the enzyme.

    Opioid analgesia alters corticospinal coupling along the descending pain system in healthy participants

    Alexandra Tinnermann, Christian Sprenger, Christian Büchel
    Corticospinal functional MRI reveals that the opioid remifentanil and the level of perceived analgesia modulate coupling strength between the prefrontal cortex, brainstem, and spinal cord.
