    Regulated aggregative multicellularity in a close unicellular relative of metazoa

    Arnau Sebé-Pedrós, Manuel Irimia ... Iñaki Ruiz-Trillo
    The transition to the aggregative stage of Capsaspora owczarzaki, a close unicellular relative to Metazoa, is associated with significant upregulation of orthologs of genes that are important for multicellularity in metazoans.

    Personality links with lifespan in chimpanzees

    Drew M Altschul, William D Hopkins ... Alexander Weiss
    Among captive chimpanzees, higher agreeableness males and higher openness females survive longer.

    Decoupled maternal and zygotic genetic effects shape the evolution of development

    Christina Zakas, Jennifer M Deutscher ... Matthew V Rockman
    Early development involves both maternal and zygotic genetic effects. This dual genetic basis shapes the evolution of developmental mode in a marine annelid.

    The Natural History of Model Organisms: The unlimited potential of the great pond snail, Lymnaea stagnalis

    István Fodor, Ahmed AA Hussein ... Zsolt Pirger
    The great pond snail is a multipurpose model organism and a contemporary choice for addressing a wide range of biological questions, problems and phenomena in the laboratory and the field.

    Experimentally guided models reveal replication principles that shape the mutation distribution of RNA viruses

    Michael B Schulte, Jeremy A Draghi ... Raul Andino
    A mathematical model that combines stochasticity and spatial structure describes the dynamics of the viral population during an infection cycle, and fitting the model to RNA and virus abundances over time shows that poliovirus follows a geometric replication mode.

    Thermal acclimation of tropical coral reef fishes to global heat waves

    Jacob L Johansen, Lauren E Nadler ... Jodie Rummer
    The ability of animals to adjust to thermal stress is critical for survival under global warming, yet the adjustment process and scope have (until now) remained obscure in marine fishes.

    A timeline of bacterial and archaeal diversification in the ocean

    Carolina A Martinez-Gutierrez, Josef C Uyeda, Frank O Aylward
    Phylogenomics reveals the timeline over which marine bacteria and archaea colonized the oceans and shows the geological context of their diversification.

    Larger but younger fish when growth outpaces mortality in heated ecosystem

    Max Lindmark, Malin Karlsson, Anna Gårdmark
    Elevated growth rates and increased size-at-age leads to a larger population size structure, despite higher mortality and a younger population after three decades of exposure to 5–10°C higher temperatures in a large-scale natural climate change experiment.

    Productivity loss associated with functional disability in a contemporary small-scale subsistence population

    Jonathan Stieglitz, Paul L Hooper ... Michael D Gurven
    Adult spinal fracture substantially impairs subsistence productivity, particularly for men.

    Life history predicts global population responses to the weather in terrestrial mammals

    John Jackson, Christie Le Coeur, Owen Jones
    In mammals, how populations respond to extremes in the weather is related to their pace of life, with shorter living species having stronger responses than their longer living counterparts.
