    Ventrolateral periaqueductal gray neurons prioritize threat probability over fear output

    Kristina M Wright, Michael A McDannald
    Single-unit activity in the ventrolateral periaqueductal gray, a brain region implicated in organizing fear output, is found to reflect threat probability, a more versatile threat signal.

    Body height in young adult men and risk of dementia later in adult life

    Terese Sara Høj Jørgensen et al.
    Taller body height in young adulthood, as marker of early-life environment, is associated with lower risk of dementia diagnosis independently of cognitive reserve and family factors shared among brothers.

    The structure of photosystem I from a high-light-tolerant cyanobacteria

    Zachary Dobson et al.
    The necessity of studying extremophile organisms is exemplified by the structure of photosystem I from a high-light tolerant cyanobacteria, demonstrating the relationship between the structure and function in photosystem I.

    Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy

    Sona Valuchova et al.
    Light sheet microscopy was used to establish a method for live imaging of cellular events within Arabidopsis flower and for constructing a 3D model of flower at subcellular resolution.

    Light-at-night exposure affects brain development through pineal allopregnanolone-dependent mechanisms

    Shogo Haraguchi et al.
    Diurnal variation loss of pineal allopregnanolone synthesis by light-at-night induces pituitary adenylate cyclase-activating polypeptide (PACAP) reduction and transcriptional PACAP repression in the cerebellum, with subsequent Purkinje cell death.

    Weight loss, insulin resistance, and study design confound results in a meta-analysis of animal models of fatty liver

    Harriet Hunter et al.
    Animal studies of fatty liver disease over-estimate the benefit of drugs due to publication bias and are confounded by off-target weight loss, illustrating the challenge of successful translational across species.

    Optical dopamine monitoring with dLight1 reveals mesolimbic phenotypes in a mouse model of neurofibromatosis type 1

    J Elliott Robinson et al.
    Heterozygous Nf1 knockout mice exhibit distinct dopaminergic phenotypes in vivo, as revealed by the genetically encoded dopamine sensor dLight1, patch clamp electrophysiology, optogenetics, and novel viral tools for morphological analysis.

    A transcriptomics resource reveals a transcriptional transition during ordered sarcomere morphogenesis in flight muscle

    Maria L Spletter et al.
    A developmental transcriptomics resource from Drosophila flight muscles quantifies the transcriptional dynamics during muscle morphogenesis and identifies three ordered phases of sarcomere morphogenesis.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti et al.
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    A Ras-like domain in the light intermediate chain bridges the dynein motor to a cargo-binding region

    Courtney M Schroeder et al.
    The dynein light intermediate chain is a member of the G protein superfamily and links the motor to several intracellular cargo adaptors.
