    Migration confers winter survival benefits in a partially migratory songbird

    Daniel Zúñiga et al.
    Testing of fitness-related benefits in migratory population of European blackbirds offers confirming predictions of theoretical models on the evolution and maintenance of migration.

    Research: A comprehensive and quantitative exploration of thousands of viral genomes

    Gita Mahmoudabadi, Rob Phillips
    A compendium of critical genomic numbers for viruses through the lenses of different viral classification systems.

    Cooperative interactions enable singular olfactory receptor expression in mouse olfactory neurons

    Kevin Monahan et al.
    Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    Human embryonic lung epithelial tips are multipotent progenitors that can be expanded in vitro as long-term self-renewing organoids

    Marko Z Nikolić et al.
    Improved characterisation of human embryonic lung development highlights human-mouse differences and facilitates the development of defined culture conditions for the expansion of self-renewing, multipotent human lung epithelial progenitor cells.

    Genetic and environmental influences on adult human height across birth cohorts from 1886 to 1994

    Aline Jelenkovic et al.
    Genetic variance of adult human height shows a generally increasing trend across the birth-year cohorts but heritability estimates do not present any clear pattern of secular changes over a century.

    The evolution of non-reproductive workers in insect colonies with haplodiploid genetics

    Jason W Olejarz et al.
    A mathematical model predicts the precise conditions for natural selection to favor the evolution of non-reproductive workers in insect colonies with haplodiploid genetics.

    Functionally defined white matter of the macaque monkey brain reveals a dorso-ventral attention network

    Ilaria Sani et al.
    Primate attention is not limited to a dorsal fronto-parietal network, but includes a ventral temporal node and its dorso-ventral interactions with other attentional areas.

    Odd-paired controls frequency doubling in Drosophila segmentation by altering the pair-rule gene regulatory network

    Erik Clark, Michael Akam
    The organisation of the Drosophila embryo into segmental units is orchestrated by combinatorial regulatory interactions between spatially patterned and temporally patterned transcription factors.

    The Caenorhabditis elegans protein SAS-5 forms large oligomeric assemblies critical for centriole formation

    Kacper B Rogala et al.
    SAS-5 forms oligomers, through a trimeric coiled coil and novel dimeric domain, that are necessary for centriolar localisation of SAS-5 and for centriole duplication.
