    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.

    A theory of working memory without consciousness or sustained activity

    Darinka Trübutschek et al.
    Visual information can be maintained in non-conscious working memory for several seconds via short-term changes in synaptic weights.

    Genetic specification of left–right asymmetry in the diaphragm muscles and their motor innervation

    Camille Charoy et al.
    Analysis of embryonic mouse diaphragm reveals muscle and nerve left–right asymmetries set by a Nodal-dependent genetic cascade, which imprints different molecular signatures to left and right motoneurons that shape their innervation pattern.

    The force-sensing peptide VemP employs extreme compaction and secondary structure formation to induce ribosomal stalling

    Ting Su et al.
    The structure of the VemP-stalled ribosome reveals a helix-double turn-helix conformation of the nascent chain within the ribosomal tunnel, illustrating how secondary structure formation directly at the peptidyltransferase center of the ribosome can induce translational arrest.

    sRNA-mediated activation of gene expression by inhibition of 5'-3’ exonucleolytic mRNA degradation

    Sylvain Durand et al.
    Small regulatory RNAs are able to modulate mRNA degradation rates by controlling access to the 5' end of mRNAs in bacteria.

    9Å structure of the COPI coat reveals that the Arf1 GTPase occupies two contrasting molecular environments

    Svetlana O Dodonova et al.
    A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.

    Operon mRNAs are organized into ORF-centric structures that predict translation efficiency

    David H Burkhardt et al.
    Operonic mRNAs in bacteria are comprised of ORF (open reading frame)-wide units of secondary structure, which are intrinsically distinct between adjacent ORFs and encode a rough blueprint for ORF-specific translation efficiency.

    PPP1R15A-mediated dephosphorylation of eIF2α is unaffected by Sephin1 or Guanabenz

    Ana Crespillo-Casado et al.
    The notion that the drug-like small molecule Sephin1 protects against protein misfolding by selectively disrupting a cellular phosphatase is refuted.

    Constitutive activation of kappa opioid receptors at ventral tegmental area inhibitory synapses following acute stress

    Abigail M Polter et al.
    Rats exposed to a single stressful event experience days-long constitutive activation of the kappa opioid receptor at inhibitory synapses in part of the brain’s reward system, which increases their drug-seeking behavior.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.
