    An adaptation of astronomical image processing enables characterization and functional 3D mapping of individual sites of excitation-contraction coupling in rat cardiac muscle

    Qinghai Tian et al.
    The fusion of astronomy and cellular cardiology reveals the 3D arrangement and the firing reliability of active excitation-contraction coupling sites in beating cardiac myocytes.

    Cardiac ryanodine receptor distribution is dynamic and changed by auxiliary proteins and post-translational modification

    Parisa Asghari et al.
    Repositioning the type II ryanodine receptors on the sarcoplasmic reticulum membrane is a potential new mechanism regulating their function, and therefore the strength of cardiac contraction.

    Apolipoprotein M-bound sphingosine-1-phosphate regulates blood–brain barrier paracellular permeability and transcytosis

    Mette Mathiesen Janiurek et al.
    Shortage of blood-borne apolipoprotein-M–bound sphingosine-1-phosphate, which accompanies various brain disorders, causes paracellular leak and increase in transcytosis at the blood–brain barrier, which can be reversed, thus is of clinical relevance.

    Single cell, super-resolution imaging reveals an acid pH-dependent conformational switch in SsrB regulates SPI-2

    Andrew Tze Fui Liew et al.
    Inside the acidic vacuole, expression, DNA binding and DNA binding affinity of the Salmonella regulator SsrB is stimulated by acid pH.

    Non-enzymatic primer extension with strand displacement

    Lijun Zhou et al.
    Relying on RNA fragments derived from degradation or partial template copying, non-enzymatic primer extension with strand displacement offers a novel and prebiotically plausible approach to RNA self-replication.

    The distribution of fitness effects among synonymous mutations in a gene under directional selection

    Eleonore Lebeuf-Taylor et al.
    Synonymous mutations can have highly variable fitness effects stemming from changes in transcription, some of which contribute to adaptation.
