    Evolutionary dynamics of circular RNAs in primates

    Gabriela Santos-Rodriguez et al.
    An analysis of the genomic features that distinguish conserved from species-specific circular RNAs reveals that the expansion of the downstream intron by insertion of retrotransposons stabilizes circular RNAs' production across 30+ millions years of evolution.

    Switch-like and persistent memory formation in individual Drosophila larvae

    Amanda Lesar et al.
    A new computer controlled behavioral assay and integrated training chamber for individual Drosophila larvae shows that larvae learn all at once and create long-term memories that last overnight.

    Information content differentiates enhancers from silencers in mouse photoreceptors

    Ryan Z Friedman et al.
    Silencers and enhancers targeted by a common transcription factor in photoreceptors are distinguished by the number and diversity of binding transcription factor binding sites they contain.

    Analysis of meiosis in Pristionchus pacificus reveals plasticity in homolog pairing and synapsis in the nematode lineage

    Regina Rillo-Bohn et al.
    Investigation of meiosis in the nematode Pristionchus pacificus has illuminated evolutionary variation in this essential aspect of reproduction and established a new model for future study.

    Sleeping at the switch

    Maude Bouchard et al.
    Slow and fast switcher slow waves in human sleep show distinct EEG connectivity patterns and homeostatic regulation as well as changes during aging.

    Ancient role of sulfakinin/cholecystokinin-type signalling in inhibitory regulation of feeding processes revealed in an echinoderm

    Ana B Tinoco et al.
    Starfish feed by everting their stomach out of their mouth over prey and, interestingly, this unusual feeding mechanism is inhibited by substances similar to hormones that regulate feeding in humans.

    Hybrid protein assembly-histone modification mechanism for PRC2-based epigenetic switching and memory

    Cecilia Lövkvist et al.
    Extra protein memory storage elements with positive feedbacks, in addition to histone modifications, can explain epigenetic switching and memory at the PRC2 target gene FLOWERING LOCUS C (FLC).

    Dual mechanisms of opioid-induced respiratory depression in the inspiratory rhythm-generating network

    Nathan A Baertsch et al.
    Opioids cause hyperpolarization and pre-synaptic suppression among a subset of preBötzinger Complex neurons to impair respiratory rhythmogenesis.
