    Internal states drive nutrient homeostasis by modulating exploration-exploitation trade-off

    Verónica María Corrales-Carvajal et al.
    A quantitative video tracking analysis reveals that to gain the nutrients they need, flies change their decisions to exploit foods with different nutrient contents and explore the environment according to their internal amino acid and reproductive states.

    P1 interneurons promote a persistent internal state that enhances inter-male aggression in Drosophila

    Eric D Hoopfer et al.
    A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.

    Internal amino acid state modulates yeast taste neurons to support protein homeostasis in Drosophila

    Kathrin Steck et al.
    Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.

    A twist defect mechanism for ATP-dependent translocation of nucleosomal DNA

    Jessica Winger et al.
    Based on its nucleotide-bound state, the Chd1 chromatin remodeler can locally alter DNA twist on the nucleosome, which either pulls in or expels ~1 bp of DNA at the internal SHL2 binding site.

    Structural characterization of ribosome recruitment and translocation by type IV IRES

    Jason Murray et al.
    A Internal Ribosomal Entry Site RNA has been visualised by high resolution cryoEM, trapped in the ribosome in an intermediate state of translocation.

    Gastrulation: May the force be with you

    Shinuo Weng, John B Wallingford
    Understanding the coordination of the forces generated in embryos by two processes, convergent extension and convergent thickening, is key to understanding how a hollow sphere of cells develops into an elongated embryo.

    Piezo Ion Channels: Portraits of a pressure sensor

    Alexander T Chesler, Marcin Szczot
    Near atomic-resolution structures have provided insights into the mechanisms by which the Piezo1 ion channel senses and responds to mechanical stimuli.

  1. Point of view: Motivating participation in open science by examining researcher incentives

    Sarah E Ali-Khan et al.
    A survey of researchers at the Montreal Neurological Institute and Hospital provides insights into the challenges and opportunities involved in adopting an open science policy across an entire patient-oriented academic institution.
