    Individual crop loads provide local control for collective food intake in ant colonies

    Efrat Esther Greenwald et al.
    Colony satiation level determines the unloading rate of laden foragers, which, in turn, rely on their own food load to adjust their foraging effort.

    Increasing plant diversity with border crops reduces insecticide use and increases crop yield in urban agriculture

    Nian-Feng Wan et al.
    Plant diversification can make an important contribution to ecological intensification and the sustainable use of associated ecosystem services in an urban ecosystem.

    An efficient CRISPR-based strategy to insert small and large fragments of DNA using short homology arms

    Oguz Kanca et al.
    Optimization of homology donor DNA production and integration schemes facilitates homologous recombination in vivo and in cell culture in Drosophila melanogaster..

    SUMOylation of NaV1.2 channels mediates the early response to acute hypoxia in central neurons

    Leigh D Plant et al.
    The immediate response of the brain to a sudden, harmful drop in oxygen supply is the addition of SUMO proteins to sodium ion channels in neurons, increasing their activity.

    Filament formation by metabolic enzymes is a specific adaptation to an advanced state of cellular starvation

    Ivana Petrovska et al.
    A starvation-induced drop in cytosolic pH promotes assembly of budding yeast glutamine synthetase into enzymatically inactive filaments that function as enzyme storage depots.

    Hidden shift of the ionome of plants exposed to elevated CO2 depletes minerals at the base of human nutrition

    Irakli Loladze
    Increasing levels of atmospheric carbon dioxide reduce the mineral content but increase the levels of starch and sugars found in crop plants; which could exacerbate both obesity and malnutrition in some human populations.

    Ion Channels: From ions to insulin

    Voula Kanelis
    Electron cryo-microscopy has revealed the three-dimensional structure of a potassium channel that has a central role in regulating the release of insulin from the pancreas.

    Polygenic Scores: It is time to get real when trying to predict educational performance

    Cecile Janssens
    A study of 3,500 children in the UK shows that data on socioeconomic background and previous educational achievements can better predict how students will perform at school than genetic data.
