    Organization and function of Drosophila odorant binding proteins

    Nikki K Larter, Jennifer S Sun, John R Carlson
    A genetic analysis reveals that some olfactory sensilla of Drosophila do not require an abundant odorant binding protein and that one such protein may act in gain control.

    A moth odorant receptor highly expressed in the ovipositor is involved in detecting host-plant volatiles

    Rui-Ting Li, Ling-Qiao Huang ... Chen-Zhu Wang
    A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.

    Robust olfactory responses in the absence of odorant binding proteins

    Shuke Xiao, Jennifer S Sun, John R Carlson
    Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.
    1. Neuroscience

    Mapping odorant sensitivities reveals a sparse but structured representation of olfactory chemical space by sensory input to the mouse olfactory bulb

    Shawn D Burton, Audrey Brown ... Matt Wachowiak
    Large-scale mapping of sensory input to the mouse olfactory bulb reveals exceptionally narrow tuning of olfactory receptor input to glomeruli and defines a functional map of glomerular sensitivities that is structured with respect to olfactory chemical space.

    A hypothesis on the capacity of plant odorant-binding proteins to bind volatile isoprenoids based on in silico evidences

    Deborah Giordano, Angelo Facchiano ... Francesco Loreto
    It is hypothesized that volatile organic compounds emitted by plants after stress induction may be sensed by neighboring eavesdropping plants using odorant-binding proteins.

    Olfactory receptor neurons use gain control and complementary kinetics to encode intermittent odorant stimuli

    Srinivas Gorur-Shandilya, Mahmut Demir ... Thierry Emonet
    Olfactory receptor neurons adapt to odorant mean and variance and use complementary kinetics to preserve the timing of odorant encounters, despite adaptation slowing down transduction.
  1. Research Culture: A survey of early-career researchers in Australia

    Katherine Christian, Carolyn Johnstone ... Michael R Doran
    Job insecurity is putting stress on early-career researchers in Australia, compromising their career development and potentially reducing the quality of research.

    An open-source device for measuring food intake and operant behavior in rodent home-cages

    Bridget A Matikainen-Ankney, Thomas Earnest ... Alexxai V Kravitz
    An open-source behavioral platform allows for operant, feeding, and circadian experiments in rodent home-cages.

    Adaptation of olfactory receptor abundances for efficient coding

    Tiberiu Teşileanu, Simona Cocco ... Vijay Balasubramanian
    A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.

    The seminal odorant binding protein Obp56g is required for mating plug formation and male fertility in Drosophila melanogaster

    Nora C Brown, Benjamin Gordon ... Mariana Federica Wolfner
    A functional genetics approach reveals a novel role for odorant binding proteins in post-mating processes, with complex mechanisms of evolutionary change across closely related insect species.
