    Sensitive red protein calcium indicators for imaging neural activity

    Hod Dana et al.
    Protein engineering and large-scale screening has led to the development of sensitive red fluorescent indicators that detect neural activity with high sensitivity in various animal models.

    High levels of histones promote whole-genome-duplications and trigger a Swe1WEE1-dependent phosphorylation of Cdc28CDK1

    Douglas Maya Miles et al.
    Ploidy is stably maintained in Saccharomyces cerevisae by a tight coordination between histone levels and cell cycle events.

    Codon choice directs constitutive mRNA levels in trypanosomes

    Janaina de Freitas Nascimento et al.
    The information for mRNAs expression level is set by codon choice in trypanosomes and requires translation to be interpreted into a turnover rate.

    Single-molecule fluorimetry and gating currents inspire an improved optical voltage indicator

    Jeremy S Treger et al.
    ArcLight, a popular optogenetic reporter of voltage, is studied at both single-molecule and macroscopic levels, which leads to new mechanistic understanding and to the rational design of a faster reporter.

    Mechanism of environmentally driven conformational changes that modulate H-NS DNA-bridging activity

    Ramon A van der Valk et al.
    The DNA-bridging efficiency of H-NS, a genome organising and transcription regulatory protein, is modulated by changes in environmental conditions of the cell, which drive a structural rearrangement of the protein.

    Telomerase biogenesis requires a novel Mex67 function and a cytoplasmic association with the Sm7 complex

    Yulia Vasianovich et al.
    A new tool that allows specific subpopulations of telomerase RNAs in vivo forces a thorough revision of the telomerase maturation pathway and suggests a new function for Mex67.

    Ecdysone steroid hormone remote controls intestinal stem cell fate decisions via the PPARγ-homolog Eip75B in Drosophila

    Lisa Zipper et al.
    A systemic hormone controls progenitor fate decisions independent of local fate determining pathways in the adult intestinal stem cell niche of Drosophila melanogaster..

    Two-photon calcium imaging of the medial prefrontal cortex and hippocampus without cortical invasion

    Masashi Kondo et al.
    Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.

    Relationship between simultaneously recorded spiking activity and fluorescence signal in GCaMP6 transgenic mice

    Lawrence Huang et al.
    Simultaneous calcium imaging and cell-attached recording in GCaMP6 transgenic mice in vivo reveals spiking-fluorescence relationship that supports more refined inference of neuronal activities from calcium imaging data.

    Recombination, meiotic expression and human codon usage

    Fanny Pouyet et al.
    Variation in codon usage among functional categories of human genes is not due to selection for translation efficiency, but to differences in intragenic recombination rate, linked to variation in meiotic transcription level.
