    Essential metabolism for a minimal cell

    Marian Breuer, Tyler M Earnest ... Zaida Luthey-Schulten
    A near-complete flux balance analysis model of a minimal cell demonstrates the high essentiality of its metabolic genes, agrees well with experimental essentiality data and suggests some further gene removals.

    Spreading of a mycobacterial cell-surface lipid into host epithelial membranes promotes infectivity

    CJ Cambier, Steven M Banik ... Carolyn R Bertozzi
    Applying bioorthogonal chemistry to the zebrafish/Mycobacterium marinum model of tuberculosis reveals that the virulence lipid PDIM must spread into epithelial cells in order for mycobacteria to establish infection.

    Evoked transients of pH-sensitive fluorescent false neurotransmitter reveal dopamine hot spots in the globus pallidus

    Jozsef Meszaros, Timothy Cheung ... David Sulzer
    Dopamine release within the mouse external globus pallidus, an area of very sparse innervation, is observed and described for the first time through a new technique: flashing false fluorescent neurotransmitters.

    An open-source, high-resolution, automated fluorescence microscope

    Ando Christian Zehrer, Ana Martin-Villalba ... Helge Ewers
    High-quality fluorescence live-cell and single molecule imaging via computer-controlled, user-assembled microscope that fits in incubator, can in large parts be 3D printed and employs open source software and electronics.

    Environment as a limiting factor of the historical global spread of mungbean

    Pei-Wen Ong, Ya-Ping Lin ... Cheng-Ruei Lee
    After domestication, the cultivation range expansion of crops was not solely dictated by human activity but instead constrained by climatic factors, which in turn resulted in distinct phenotypic characteristics of locally adaptive landraces.

    Identification of a GABAergic neural circuit governing leptin signaling deficiency-induced obesity

    Yong Han, Yang He ... Qi Wu
    A GABAergic neural circuit from AgRP to the dorsomedial hypothalamic nucleus regulates leptin-mediated feeding and energy balance through α3-GABAA signaling, which could provide a new therapeutic avenue for obesity.

    An open-source tool for automated analysis of breathing behaviors in common marmosets and rodents

    Mitchell Bishop, Maximilian Weinhold ... Shahriar SheikhBahaei
    The introduced Python tool was used to characterize breathing behaviors of common marmosets in room air and acute hypoxic (10% O2) and hypercapnic (6% CO2) conditions.
