    A new genetic strategy for targeting microglia in development and disease

    Gabriel L McKinsey, Carlos O Lizama ... Thomas D Arnold
    P2ry12-CreER robustly and specifically labels microglia in fate-mapping and ribosomal profiling experiments, revealing new markers for myeloid subpopulations in the central nervous system.

    Morphologic diversity of cutaneous sensory afferents revealed by genetically directed sparse labeling

    Hao Wu, John Williams, Jeremy Nathans
    The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.

    Defective memory engram reactivation underlies impaired fear memory recall in Fragile X syndrome

    Jie Li, Rena Y Jiang ... Lu Chen
    Activity-dependent genetic labeling during behavioral learning shows Fragile-X syndrome model mice exhibit impaired hippocampal engram reactivation, and that enriched environment experience improves fear memory retrieval by enhancing engram reactivation efficacy.

    Proximity labeling identifies LOTUS domain proteins that promote the formation of perinuclear germ granules in C. elegans

    Ian F Price, Hannah L Hertz ... Wen Tang
    A proximity labeling approach defines germ granule proteome in Caenorhabditis elegans, and identifies LOTUS domain proteins as key regulators of germ granule assembly.

    Adiposity may confound the association between vitamin D and disease risk – a lifecourse Mendelian randomization study

    Tom G Richardson, Grace M Power, George Davey Smith
    Genetic analyses provide evidence that adiposity influences vitamin D levels at different timepoints over the lifecourse, suggesting that associations previously reported between vitamin D deficiency and disease by conventional epidemiological studies may have been prone to confounding.

    Lipid transfer from plants to arbuscular mycorrhiza fungi

    Andreas Keymer, Priya Pimprikar ... Caroline Gutjahr
    Identification of two arbuscular mycorrhiza-specific lipid biosynthesis mutants and fatty acid transfer experiments reveal that host plant lipids are transferred to symbiotic fungi and needed for their development.

    Conditional protein tagging methods reveal highly specific subcellular distribution of ion channels in motion-sensing neurons

    Sandra Fendl, Renee Marie Vieira, Alexander Borst
    New protein labeling strategies unravel the subcellular distribution of neurotransmitter receptor subunits and voltage-gated ion channels in motion-sensing T4/T5 neurons of the Drosophila visual system.

    Multimodal cell tracking from systemic administration to tumour growth by combining gold nanorods and reporter genes

    Joan Comenge, Jack Sharkey ... Antonius Plagge
    Combined cell labelling with a bi-cistronic reporter-gene vector and gold nanorods enables short- and long-term cell tracking in vivo via multimodal imaging (multispectral optoacoustic tomography, bioluminescence, fluorescence) with high spatial resolution.

    Functional reconstitution of a bacterial CO2 concentrating mechanism in Escherichia coli

    Avi I Flamholz, Eli Dugan ... David F Savage
    A bacterial CO2 concentrating mechanism enables Escherichia coli to fix CO2 from ambient air into biomass.

    Strip1 regulates retinal ganglion cell survival by suppressing Jun-mediated apoptosis to promote retinal neural circuit formation

    Mai Ahmed, Yutaka Kojima, Ichiro Masai
    A neuroprotective role mediated by Strip1 maintains retinal ganglion cells during development, which ensures proper positioning of inner retinal neurons and preserves the laminar architecture of the inner retina.
