    Surface-to-volume scaling and aspect ratio preservation in rod-shaped bacteria

    Nikola Ojkic et al.
    Rod-shaped bacteria preserve their aspect ratios and surface-to-volume scaling by maintaining a homeostatic balance between the rates of cell elongation and division protein synthesis.

    Activation of GCN2 kinase by ribosome stalling links translation elongation with translation initiation

    Ryuta Ishimura et al.
    Activation of the integrated stress response by stalled translation elongation complexes attenuates neurodegeneration, and demonstrates a protective link between a decrease in the rate of translation initiation and defects in translation elongation.

    Identification of protein-protected mRNA fragments and structured excised intron RNAs in human plasma by TGIRT-seq peak calling

    Jun Yao et al.
    Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.

    The malaria parasite sheddase SUB2 governs host red blood cell membrane sealing at invasion

    Christine R Collins et al.
    Genetic analysis identifies an enzyme of the malaria parasite that is required to seal its host red blood cell membrane upon invasion, a key requirement of this important intracellular pathogen.

    Scaling of subcellular actin structures with cell length through decelerated growth

    Shane G McInally et al.
    The size of a subcellular structure, yeast actin cables, scales with the linear dimensions of the cell, which is achieved by feedback control of their growth rate.

    Learning to stand with unexpected sensorimotor delays

    Brandon G Rasman et al.
    The nervous system can learn to control standing balance with added sensorimotor delays by causally linking delayed whole-body sensory feedback, initially deemed as unexpected, to self-generated balance motor commands.

    Skin vasculature and hair follicle cross-talking associated with stem cell activation and tissue homeostasis

    Kefei Nina Li et al.
    Hair follicle epithelium and skin vasculature remodeling are coordinated during quiescence, and their cross-talking is associated with the timing of stem cell activation.

    Loss of N1-methylation of G37 in tRNA induces ribosome stalling and reprograms gene expression

    Isao Masuda et al.
    Biochemical and genome-wide analysis demonstrates that m1G37 is important for tRNA aminoacylation and for the entire elongation cycle of protein synthesis.

    Cortical signatures of precision grip force control in children, adolescents, and adults

    Mikkel Malling Beck et al.
    Precise motor control is supported by connectivity within a cortical grasping network from childhood to adulthood, but older individuals display more top-down control and superior motor performance compared to children.

    RNA polymerase II stalling at pre-mRNA splice sites is enforced by ubiquitination of the catalytic subunit

    Laura Milligan et al.
    Ubiquitination close to the active site of RNAPII occurs in response to RNA processing events and is linked to transcriptional pausing, which is released following Bre5-Ubp3 mediated deubiquitination associated with the nascent transcript.
