    The cyanobacterial circadian clock follows midday in vivo and in vitro

    Eugene Leypunskiy et al.
    The cyanobacterial core clock tracks midday regardless of day length, which can be understood in terms of a model for how the environment alters the clock limit cycle.

    Chromerid genomes reveal the evolutionary path from photosynthetic algae to obligate intracellular parasites

    Yong H Woo et al.
    Analysis of chromerid algal genomes reveals how apicomplexans have evolved from free-living algae into successful eukaryotic parasites via massive losses and re-inventing functional roles of genes.

    A new class of cyclin dependent kinase in Chlamydomonas is required for coupling cell size to cell division

    Yubing Li et al.
    CDKG1 is a D-cyclin dependent retinoblastoma related protein kinase whose abundance scales with cell size and controls cell division cycle number during multiple fission.

    Acknowledging selection at sub-organismal levels resolves controversy on pro-cooperation mechanisms

    Wenying Shou
    Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

    Aerotaxis in the closest relatives of animals

    Julius B Kirkegaard et al.
    The colony-forming choanoflagellate Salpingoeca rosetta is capable of moving towards oxygen using logarithmic sensing of oxygen concentrations and a navigation strategy that involves random movements.
