    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.

    A novel role for the root cap in phosphate uptake and homeostasis

    Satomi Kanno et al.
    Real-time 33P imaging combined with specific complementation of inorganic phosphate transport in the root cap reveals this tissue’s contribution to phosphate uptake.

    The Natural History of Model Organisms: The unexhausted potential of E. coli

    Zachary D Blount
    A better understanding of the remarkable diversity, natural history and complex ecology of E. coli in the wild could shed new light on its biology and role in disease, and further expand its many uses as a model organism.

    Meta-Research: Use of the Journal Impact Factor in academic review, promotion, and tenure evaluations

    Erin C McKiernan et al.
    Almost a quarter of faculty evaluation documents from US and Canadian universities mention Journal Impact Factor and often imply that it measures research quality.

    The Natural History of Model Organisms: The Norway rat, from an obnoxious pest to a laboratory pet

    Klaudia Modlinska, Wojciech Pisula
    The rat is much more than a simple model, and a better appreciation of the natural history of wild rats would increase its value as a research organism.

    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    Arcuate nucleus and lateral hypothalamic CART neurons in the mouse brain exert opposing effects on energy expenditure

    Aitak Farzi et al.
    CART exerts differential metabolic effects in response to activation of neurons of the Arc, where CART suppresses energy expenditure, while it enforces the reward characteristics of the LHA.
