    Emergence and diversification of a host-parasite RNA ecosystem through Darwinian evolution

    Taro Furubayashi et al.
    In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.

    Electrostatic lateral interactions drive ESCRT-III heteropolymer assembly

    Sudeep Banjade et al.
    ESCRT-III heteropolymers utilize non-specific lateral electrostatic interactions to recognize one another, which may enable the polymers to slide along one another and adapt to different curvatures.

    Speed and segmentation control mechanisms characterized in rhythmically-active circuits created from spinal neurons produced from genetically-tagged embryonic stem cells

    Matthew J Sternfeld et al.
    Stem cell derived ventral-spinal cord excitatory neurons self-assemble into a rhythmically bursting neural network whose speed and intercellular coordination are both instructively modulated by cell-type specific interactions with inhibitory neurons.

    A Cryptochrome 2 mutation yields advanced sleep phase in humans

    Arisa Hirano et al.
    A missense mutation in the human Cryptochrome 2 (CRY2) gene leads to the condition of familial advanced sleep phase.

    Modulation of let-7 miRNAs controls the differentiation of effector CD8 T cells

    Alexandria C Wells et al.
    TCR-mediated downregulation of let-7 microRNAs licenses the differentiation of activated CD8 T cells into cytotoxic T lymphocytes.

    CHARGE syndrome modeling using patient-iPSCs reveals defective migration of neural crest cells harboring CHD7 mutations

    Hironobu Okuno et al.
    Neural crest cells differentiated from patient-derived cells with mutations in the chromatin remodeler CHD7 show defective delamination, migration and motility in vitro, and defective migration in chick embryos.

    A microbial clock provides an accurate estimate of the postmortem interval in a mouse model system

    Jessica L Metcalf et al.
    High-throughput sequencing has been used to analyze the microbiome of mouse corpses over a period of 48 days, and to provide an accurate estimate of the time since death.

    Maturing Mycobacterium smegmatis peptidoglycan requires non-canonical crosslinks to maintain shape

    Catherine Baranowski et al.
    Polar elongating mycobacteria (Mycobacterium smegmatis) require specific cell wall chemistries, those catalyzed by targets of critical antibiotics, to maintain rod shape at aging sites of the bacillus.

    Host-selected mutations converging on a global regulator drive an adaptive leap towards symbiosis in bacteria

    M Sabrina Pankey et al.
    Selective forces imposed by the squid animal host drive rapid adaptation of non-native Vibrio fischeri bacteria through convergent mutations of large effect, unmasking preexisting coordinated regulation of symbiosis.
