    Optimal searching behaviour generated intrinsically by the central pattern generator for locomotion

    David W Sims et al.
    The nervous system circuitry that controls locomotion has evolved to intrinsically generate an optimal search pattern for resources.

    Heterogeneous T cell motility behaviors emerge from a coupling between speed and turning in vivo

    Elizabeth R Jerison, Stephen R Quake
    Motile interstitial T cells in live zebrafish access a broad range of length-scales due to long-lived cell-intrinsic variation in speed, and a coupling between speed and directional persistence.

    Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight

    NCD Risk Factor Collaboration (NCD-RisC)
    Changes in the prevalence of underweight, total obesity, and severe obesity are largely driven by shifts in the distribution of body mass index.

    Deciphering anomalous heterogeneous intracellular transport with neural networks

    Daniel Han et al.
    Direct estimation of the Hurst exponent shows that endosomes and lysosomes reside in regimes of persistent and anti-persistent motion with heavy-tailed residence time distributions and motion correlated with endocytic function.

    Nucleolar dynamics and interactions with nucleoplasm in living cells

    Christina M Caragine et al.
    The nucleoplasm surrounding nucleoli in living cells plays a key role in nucleolar dynamics and shape fluctuations in vivo.

    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.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    Cerebellar learning using perturbations

    Guy Bouvier et al.
    A proposal for a complete cellular/network implementation of trial-and-error motor learning in the olivo-cerebellar system.
