    Mechanisms of organelle biogenesis govern stochastic fluctuations in organelle abundance

    Shankar Mukherji, Erin K O'Shea
    A systematic comparison of experimentally measured and theoretically predicted magnitudes of organelle abundance fluctuations suggests that budding yeast produces the maximum level of variability in organelle abundance that can be generated by organelle biogenesis pathways.

    Stochastic modelling, Bayesian inference, and new in vivo measurements elucidate the debated mtDNA bottleneck mechanism

    Iain G Johnston et al.
    New modelling, statistics, and experiments show that cellular populations of mitochondrial DNA (mtDNA) evolve during development according to solvable stochastic dynamics involving binomial partitioning and random turnover, facilitating a predictive and quantitative theory of the mtDNA bottleneck.

    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.

    Stochastic bond dynamics facilitates alignment of malaria parasite at erythrocyte membrane upon invasion

    Sebastian Hillringhaus et al.
    The bond-based adhesion model is a key step toward a realistic description of RBC-parasite interaction, which allows the investigation of more realistic scenarios and is relevant for other biological systems.
