    Silencing of transposable elements may not be a major driver of regulatory evolution in primate iPSCs

    Michelle C Ward, Siming Zhao ... Yoav Gilad
    Human and chimpanzee-induced pluripotent stem cells show limited species-specificity in transposable element silencing.

    Stochastic processes constrain the within and between host evolution of influenza virus

    John T McCrone, Robert J Woods ... Adam S Lauring
    An analysis of influenza viruses from naturally infected people suggests a tight transmission bottleneck and little positive selection within hosts.

    CRISPR-based herd immunity can limit phage epidemics in bacterial populations

    Pavel Payne, Lukas Geyrhofer ... Jonathan P Bollback
    Bacteria can exhibit herd immunity protection against phages, which may play a significant role in their ecology and evolution.

    Mapping mutational effects along the evolutionary landscape of HIV envelope

    Hugh K Haddox, Adam S Dingens ... Jesse D Bloom
    Deep mutational scanning of Env proteins from two transmitted-founder strains of HIV shows how the accessible evolutionary space changes as the virus evolves.

    Origin and evolution of the nuclear auxin response system

    Sumanth K Mutte, Hirotaka Kato ... Dolf Weijers
    The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

    Two consecutive microtubule-based epithelial seaming events mediate dorsal closure in the scuttle fly Megaselia abdita

    Juan Jose Fraire-Zamora, Johannes Jaeger, Jérôme Solon
    Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

    Dynamics of venom composition across a complex life cycle

    Yaara Y Columbus-Shenkar, Maria Y Sachkova ... Yehu Moran
    Different developmental stages of a venomous animal (e.g. Nematostella vectensis) with a complex life cycle produce vastly different venoms that can serve in different antagonistic interactions with other species.

    Evolution: Oxygen and early animals

    Kalle T Rytkönen
    The biology of sponges provides clues about how early animals may have dealt with low levels of oxygen.

    The last common ancestor of animals lacked the HIF pathway and respired in low-oxygen environments

    Daniel B Mills, Warren R Francis ... Gert Wörheide
    Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

    Destructive disinfection of infected brood prevents systemic disease spread in ant colonies

    Christopher D Pull, Line V Ugelvig ... Sylvia Cremer
    Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.
