    Selection of distinct populations of dentate granule cells in response to inputs as a mechanism for pattern separation in mice

    Wei Deng et al
    By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

    Sox10-dependent neural crest origin of olfactory microvillous neurons in zebrafish

    Ankur Saxena et al
    Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

    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.

    The AFF4 scaffold binds human P-TEFb adjacent to HIV Tat

    Ursula Schulze-Gahmen et al
    Structure-function analysis of the super elongation complex formed when HIV replicates inside cells reveals that the HIV-1 Tat protein binds to a cleft between P-TEFb, an enzyme that is involved in normal transcription, and AFF4, a protein that is used to build the super elongation complex

    AP2 hemicomplexes contribute independently to synaptic vesicle endocytosis

    Mingyu Gu et al
    A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.
