    Plants regenerated from tissue culture contain stable epigenome changes in rice

    Hume Stroud et al.
    The use of tissue culture reduces the chemical modification of plant DNA, and this has lasting effects on gene expression in the plants and their descendants.

    Phasic oxygen dynamics confounds fast choline-sensitive biosensor signals in the brain of behaving rodents

    Ricardo M Santos, Anton Sirota
    Fast fluctuations of oxygen, linked to behavioral and neural dynamics in vivo, cause phasic transients is amperometry-measured cholinergic signals via the mechanism of non-steady-state enzyme kinetics in the choline-oxidase-based biosensor.

    Brain states govern the spatio-temporal dynamics of resting-state functional connectivity

    Felipe Aedo-Jury et al.
    Distinct brain states govern resting state functional architecture revealed by neurophysiologically defined simultaneous optic-fiber-based calcium recordings and task-free functional magnetic resonance imaging (fMRI) in rats.

    Lymph node stromal cells constrain immunity via MHC class II self-antigen presentation

    Antonio P Baptista et al.
    MHC class II-mediated self-antigen presentation by lymph node stromal cells controls regulatory T cell homeostasis, thus safeguarding immune tolerance.

    FGF2-FGFR1 signaling regulates release of Leukemia-Protective exosomes from bone marrow stromal cells

    Nathalie Javidi-Sharifi et al.
    Inhibition of FGF2-FGFR1 signaling in bone marrow stroma attenuates secretion of FGF2-laden exosomes and subsequent protection of leukemia cells.

    Optimal level activity of matrix metalloproteinases is critical for adult visual plasticity in the healthy and stroke-affected brain

    Justyna Pielecka-Fortuna et al.
    Matrix metalloproteinases play a crucial role in adult visual plasticity in the brains of healthy and stroke-affected mice and their activity has to be within a narrow window for experience-induced plasticity to occur.

    Attentional amplification of neural codes for number independent of other quantities along the dorsal visual stream

    Elisa Castaldi et al.
    The representations of information concerning the number, size, density and surface of sets of objects in a visual image are separable along the occipito-parietal cortex and independently modulated by attention.

    Perceptual processing in the ventral visual stream requires area TE but not rhinal cortex

    Mark AG Eldridge et al.
    Bilateral removal of cortical area 'TE' produced deficits in monkeys' ability to discriminate among images with many similar features, whereas removal of subjacent rhinal cortex did not.

    A pentameric protein ring with novel architecture is required for herpesviral packaging

    Allison L Didychuk et al.
    The first structures of Kaposi’s sarcoma-associated herpesvirus ORF68 and Epstein–Barr virus BFLF1, conserved and essential proteins required in herpesviruses, reveal new insights into viral genome packaging.

    Gap junctions deliver malonyl-CoA from soma to germline to support embryogenesis in Caenorhabditis elegans

    Todd A Starich et al.
    Malonyl-CoA, the rate-limiting substrate for fatty acid synthesis, is produced in the soma and delivered through gap junctions to the germline to promote reproduction and coordinate it with nutritional status.
