    Paths and pathways that generate cell-type heterogeneity and developmental progression in hematopoiesis

    Juliet R Girard, Lauren M Goins ... Utpal Banerjee
    A combination of mRNA sequencing and genetic analysis reveals mechanisms that govern the development of distinct differentiated blood cell types from hematopoietic progenitors.

    A feed-forward pathway drives LRRK2 kinase membrane recruitment and activation

    Edmundo G Vides, Ayan Adhikari ... Suzanne R Pfeffer
    Parkinson’s disease-associated LRRK2 kinase is recruited to membranes by its Rab GTPase substrates, and LRRK2 is both retained on membranes and further activated there by cooperative interaction with the phosphorylated Rab proteins that it generates.

    Semantic relatedness proactively benefits learning, memory, and interdependence across episodes

    Kelly A Bennion, Jade Phong ... James W Antony
    Increasing semantic relationships with old information accelerates learning and enhances memory for new information and increases the likelihood of both old and new information being recalled together.

    Cryo-plasma FIB/SEM volume imaging of biological specimens

    Maud Dumoux, Thomas Glen ... Michael Grange
    Implementation and characterisation of plasma-focused ion beams for volumetric imaging of cryogenically preserved cells and tissues for ultrastructural examination in their native state.

    Genomic architecture and evolutionary antagonism drive allelic expression bias in the social supergene of red fire ants

    Carlos Martinez-Ruiz, Rodrigo Pracana ... Yannick Wurm
    Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.

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

    Allison L Didychuk, Stephanie N Gates ... Britt A Glaunsinger
    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.

    Semantic relatedness retroactively boosts memory and promotes memory interdependence across episodes

    James W Antony, America Romero ... Kelly A Bennion
    The more semantically related a later experience is to an earlier one (along multiple dimensions), the more likely humans are to think back to and strengthen the memory of the earlier experience and mentally link the two experiences.

    MeCP2 regulates Gdf11, a dosage-sensitive gene critical for neurological function

    Sameer S Bajikar, Ashley G Anderson ... Huda Y Zoghbi
    Integrated analysis of transcriptional profiles from mice carrying distinct Mecp2 mutant alleles revealed that MeCP2 regulates Gdf11 expression in the brain, and that Gdf11 is a dosage-sensitive gene whose levels impact neuronal function and animal behavior.

    Localized inhibition in the Drosophila mushroom body

    Hoger Amin, Anthi A Apostolopoulou ... Andrew C Lin
    A large interneuron in the Drosophila mushroom body has compartmentalized activity, which causes localized inhibition and predicts that Kenyon cells inhibit themselves more than they inhibit other individual Kenyon cells.

    Arcuate hypothalamic AgRP and putative POMC neurons show opposite changes in spiking across multiple timescales

    Yael Mandelblat-Cerf, Rohan N Ramesh ... Mark L Andermann
    Gradual changes in the firing of specific hypothalamic neurons over many hours signal falling energy levels, while short-lived changes over seconds and minutes signal the availability of food.
