    Olfactory responses of Drosophila are encoded in the organization of projection neurons

    Kiri Choi, Won Kyu Kim, Changbong Hyeon
    The organization of olfactory projection neurons and their synaptic connectivity with third-order neurons studied along with olfactory responses suggest that the labeled-line design is partially at work in the Drosophila olfactory system.

    Local generation and efficient evaluation of numerous drug combinations in a single sample

    Vlad Elgart, Joseph Loscalzo
    Engineered local heterogeneity in drug concentration is used as a tool to encode drug treatment regimens and to predict the macroscopic cellular response to drug perturbations.

    Integrative dynamic structural biology unveils conformers essential for the oligomerization of a large GTPase

    Thomas-O Peulen, Carola S Hengstenberg ... Christian Herrmann
    Multimodal spectroscopy (smFRET, EPR, SAXS, and SANS) and integrative structural modeling reveal large-scale domain rearrangements in human guanylate binding protein 1 (hGBP1) that are driving forces for the formation of oligomers that enable its biological function in innate immune defense.

    Gigapixel imaging with a novel multi-camera array microscope

    Eric E Thomson, Mark Harfouche ... Eva A Naumann
    A new multi camera imaging platform simultaneously captures large-area, high-resolution video of unconstrained small model organisms and provides behavioral measurements that span multiple spatial scales.

    Designed α-sheet peptides inhibit amyloid formation by targeting toxic oligomers

    Gene Hopping, Jackson Kellock ... Valerie Daggett
    Novel designed alpha-sheet peptides inhibit amyloidosis in two different systems and preferentially bind the toxic oligomer.

    tp53 deficiency causes a wide tumor spectrum and increases embryonal rhabdomyosarcoma metastasis in zebrafish

    Myron S Ignatius, Madeline N Hayes ... David M Langenau
    Syngeneic tp53-null zebrafish develop a wide range of tumors that engraft into recipient animals with loss of Tp53 leading to increased metastasis in embryonal rhabdomyosarcoma (ERMS), likely accounting for increased aggression in TP53-inactivated human ERMS.

    A meta-analysis of genome-wide association studies of childhood wheezing phenotypes identifies ANXA1 as a susceptibility locus for persistent wheezing

    Raquel Granell, John A Curtin ... Adnan Custovic
    Using unique data from five longitudinal UK birth cohorts, four distinct subsets of genetic variants were identified as differentially associated across wheezing phenotypes from infancy to adolescence with little evidence of genetic associations spanning across different phenotypes.

    Large-scale cell-type-specific imaging of protein synthesis in a vertebrate brain

    Or David Shahar, Erin Margaret Schuman
    The development of a transgenic zebrafish allows for cell-type-specific labeling of neuronal protein synthesis, enabling brain-wide visualization and quantification of protein synthesis and demonstrating region-specific increases following elevated brain activity.

    One-step efficient generation of dual-function conditional knockout and geno-tagging alleles in zebrafish

    Wenyuan Li, Yage Zhang ... Bo Zhang
    Conditional gene knockout in combination with fluorescent labeling of different alleles can be achieved with high efficiency in zebrafish through NHEJ-mediated targeted insertion using a CRISPR/Cas system.

    A distributed residue network permits conformational binding specificity in a conserved family of actin remodelers

    Theresa Hwang, Sara S Parker ... Amy E Keating
    A peptide from PCARE achieves >100-fold binding specificity for the EVH1 domain of ENAH, a protein important for metastasis, using a conformational shift mechanism unavailable to ENAH's closely related paralogs VASP and EVL.
