    Division of Labour: Losing out to improve group fitness

    Jos Kramer, Rolf Kümmerli
    A mathematical model provides clues as to why members of a group divide tasks between them even when specialisation reduces the performance of individuals.

    Evolutionary transcriptomics implicates new genes and pathways in human pregnancy and adverse pregnancy outcomes

    Katelyn Mika, Mirna Marinić ... Vincent J Lynch
    Comparative studies of gene expression in the uterus during pregnancy identifies new genes important for pregnancy and associated with complications such as preterm birth.

    Pathogen invasion-dependent tissue reservoirs and plasmid-encoded antibiotic degradation boost plasmid spread in the gut

    Erik Bakkeren, Joana Anuschka Herter ... Wolf-Dietrich Hardt
    Bacterial gut pathogens that invade into host tissues during infection can boost the spread and accumulation of plasmids over time by forming reservoirs containing these plasmids within host tissues.

    High rates of evolution preceded shifts to sex-biased gene expression in Leucadendron, the most sexually dimorphic angiosperms

    Mathias Scharmann, Anthony G Rebelo, John R Pannell
    In the dioecious plant genus Leucadendron, shifts to sex-biased gene expression occurred predominantly in genes with ancestrally high rates of expression evolution, and were not correlated with morphology.

    A small, computationally flexible network produces the phenotypic diversity of song recognition in crickets

    Jan Clemens, Stefan Schöneich ... Berthold Hedwig
    A computational model of the neuronal network that recognizes mating signals reveals network properties that support and constrain behavioral diversity in a species group.

    Dinosaur bonebed amber from an original swamp forest soil

    Sergio Álvarez-Parra, Ricardo Pérez-de la Fuente ... Xavier Delclòs
    The most prolific and oldest locality in which a rich dinosaur bonebed and fossiliferous amber have been found in association is revealed, allowing the reconstruction of an ancient terrestrial ecosystem with a detail and accuracy reached only exceptionally in palaeontology.

    Ovipositor and mouthparts in a fossil insect support a novel ecological role for early orthopterans in 300 million years old forests

    Lu Chen, Jun-Jie Gu ... Olivier Béthoux
    Hundreds of fossil remains shed new light on the evolution of grasshoppers, gryllids, and katydids and their ecological role 300 million years ago.

    Wings and halteres act as coupled dual oscillators in flies

    Tanvi Deora, Siddharth S Sane, Sanjay P Sane
    Flight system of flies is driven by wings and mechanosensory halteres that operate as independently driven but coupled oscillators, thereby imparting robustness against wing or thorax damage.

    New fossils of Australopithecus sediba reveal a nearly complete lower back

    Scott A Williams, Thomas Cody Prang ... Lee R Berger
    Newly recovered lumbar vertebrae belonging to Malapa Hominin 2, an adult female of the fossil hominin species Australopithecus sediba, demonstrate that this individual was adapted to upright posture and bipedal locomotion but also had adaptations for climbing in trees.

    Biomarkers in a socially exchanged fluid reflect colony maturity, behavior, and distributed metabolism

    Sanja M Hakala, Marie-Pierre Meurville ... Adria C LeBoeuf
    Socially exchanged fluids passed mouth-to-mouth in ant colonies contain protein signatures of colony maturity and individual behavioral role, indicating that this fluid may underlie a distributed metabolism that functions over the scale of the colony.
