    Drosophila PSI controls circadian period and the phase of circadian behavior under temperature cycle via tim splicing

    Lauren E Foley et al.
    A screen targeting RNA-associated proteins reveals that PSI regulates timeless alternative splicing and thus controls the period of Drosophila circadian behavior and its phase under temperature cycles.

    A single clonal lineage of transmissible cancer identified in two marine mussel species in South America and Europe

    Marisa A Yonemitsu et al.
    A transmissible cancer that arose in a marine mussel spread from a single animal to become a global pathogen affecting two other mussel species in both Europe and South America.

    Dissection of central clock function in Drosophila through cell-specific CRISPR-mediated clock gene disruption

    Rebecca Delventhal et al.
    Through novel, cell-specific CRISPR tools to disrupt molecular clock genes, it was revealed that circadian rhythms are coordinated through a network, rather than by the clock of 'master regulatory' neurons.

    Single-amino acid variants reveal evolutionary processes that shape the biogeography of a global SAR11 subclade

    Tom O Delmont et al.
    An in-depth metagenomic analysis of possibly the most abundant and widespread microbial lineage in the surface ocean teases apart evolutionary processes that maintain its genomic heterogeneity and biogeography.

    Neuroanatomy of a hydrothermal vent shrimp provides insights into the evolution of crustacean integrative brain centers

    Julia Machon et al.
    A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.

    5α-cyprinol sulfate, a bile salt from fish, induces diel vertical migration in Daphnia

    Meike Anika Hahn et al.
    A fish-derived bile salt was shown to act as interspecific infochemical, inducing the widespread predator avoidance behavior diel vertical migration at picomolar concentrations in freshwater zooplankton of the genus Daphnia.

    Kairomones: Finding the fish factor

    Georg Pohnert
    The water flea Daphnia moves to deeper waters to avoid predators when it detects a chemical produced by fish.

    'Palaeoshellomics’ reveals the use of freshwater mother-of-pearl in prehistory

    Jorune Sakalauskaite et al.
    Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

    The Hox transcription factor Ubx stabilizes lineage commitment by suppressing cellular plasticity in Drosophila

    Katrin Domsch et al.
    The Hox transcription factor Ultrabithorax (Ubx) represses alternative gene programs during lineage development by lineage-specific Polycomb protein complex retention at Ubx-targeted chromatin sites.

    Adaptation of olfactory receptor abundances for efficient coding

    Tiberiu Teşileanu et al.
    A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.
