    Poly(A) tail length regulates PABPC1 expression to tune translation in the heart

    Sandip Chorghade et al.
    A poly(A) tail-based regulatory mechanism dynamically controls PABPC1 protein synthesis in cardiomyocytes and thereby titrates cellular translation in response to developmental and hypertrophic cues.

    Bi-fated tendon-to-bone attachment cells are regulated by shared enhancers and KLF transcription factors

    Shiri Kult et al.
    The molecular identity of bi-fated tendon-to-bone attachment cells, which display a mixture of transcriptomes of two neighboring cell types, enables the formation of the unique transitional tissue of the enthesis.

    Translation of 5′ leaders is pervasive in genes resistant to eIF2 repression

    Dmitry E Andreev et al.
    Most of the mRNAs whose translation is resistant to the stress-induced repression of protein synthesis contain upstream open reading frames that are efficiently translated under normal conditions.

    tRNA genes rapidly change in evolution to meet novel translational demands

    Avihu H Yona et al.
    Experimental evolution and systematic sequence analysis of transfer RNA genes reveal that anticodon mutations provide adaptive plasticity to the translation machinery.

    Effective dynamics of nucleosome configurations at the yeast PHO5 promoter

    Michael Roland Wolff et al.
    The integration of multi-nucleosome configuration data with histone turnover and new chromatin accessibility data by systematically investigated 'regulated on-off-slide' models reveals promoter state transitions regulated by just one assembly process.

    Direct measurement of the mechanical work during translocation by the ribosome

    Tingting Liu et al.
    ‘Optical tweezers’ measurements of single ribosomes and single mRNA molecules show that the translation rate depends exponentially on the applied force, and suggests that the ribosome functions as a Brownian ratchet.

    The proneural wave in the Drosophila optic lobe is driven by an excitable reaction-diffusion mechanism

    David J Jörg et al.
    A model of signalling pathways interacting with proneural gene expression explains the sequential patterning of the largest visual processing centre in the developing Drosophila brain.

    New light shed on the early evolution of limb-bone growth plate and bone marrow

    Jordi Estefa et al.
    A three-dimensional investigation of extinct-tetrapod limbs shows that even though bone elongation and blood-cell production are intimately related to mammal long bones, these functions actually appeared successively in tetrapod evolution.

    Translational control of one-carbon metabolism underpins ribosomal protein phenotypes in cell division and longevity

    Nairita Maitra et al.
    Extensive molecular profiling shows how loss of highly similar, paralogous ribosomal proteins lead to distinct phenotypic outputs, through translational control of specific mRNAs.

    tRNA sequences can assemble into a replicator

    Alexandra Kühnlein et al.
    Rudimentary cross-catalytic replication can be established by double-hairpins of tRNA-like sequences, implying that replication and translation could have emerged along a common evolutionary trajectory.
