    Transition between fermentation and respiration determines history-dependent behavior in fluctuating carbon sources

    Bram Cerulus et al.
    Live-cell microscopy and genome-wide screens reveal how slow transitions in metabolism can underlie metabolic memory, providing a model for organisms demonstrating similar history-dependent behaviour and routes to improve industrial microbes.

    A novel role for Ets4 in axis specification and cell migration in the spider Parasteatoda tepidariorum

    Matthias Pechmann et al.
    In the spider Parasteatoda tepidariorum the transcription factor Ets4 is needed for cumulus integrity, dorsoventral patterning and for the activation of hunchback and twist expression.

    Protein sequences bound to mineral surfaces persist into deep time

    Beatrice Demarchi et al.
    A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

    A new protocol for single-cell RNA-seq reveals stochastic gene expression during lag phase in budding yeast

    Abbas Jariani et al.
    A new high-throughput method for single-cell RNA-seq in yeast cells shows how stochastic expression of glucose-repressed genes contributes to cell-to-cell differences during adaptation to an environmental change.

    Nuclear receptor Ftz-f1 promotes follicle maturation and ovulation partly via bHLH/PAS transcription factor Sim

    Elizabeth M Knapp et al.
    Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.

    TRPV4 is the temperature-sensitive ion channel of human sperm

    Nadine Mundt et al.
    The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.

    Fitness effects of altering gene expression noise in Saccharomyces cerevisiae

    Fabien Duveau et al.
    The impact of changing gene expression noise on fitness reveals beneficial or deleterious effects in a stable environment depending how close the average expression level is to the fitness optimum.

    Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field

    Arne Weinhold et al.
    The attempt to manipulate a microbiome in planta to study the ecological consequences under field conditions leaves plants and their microbes surprisingly unimpressed.
