    Place-cell capacity and volatility with grid-like inputs

    Man Yi Yim, Lorenzo A Sadun ... Thibaud Taillefumier
    A very large number of place-field maps can be robustly learned by association of external cues with the grid-driven response, however plasticity in the grid-cell inputs renders the place-cell responses volatile.

    Polygenic adaptation after a sudden change in environment

    Laura Katharine Hayward, Guy Sella
    A shift in fitness optimum of a polygenic trait rapidly introduces small frequency differences between alleles with effects aligned with and opposing the shift, which gradually translate into small differences in fixation probability.

    High-density sampling reveals volume growth in human tumours

    Arman Angaji, Michel Owusu ... Johannes Berg
    Spatial genomics reveals the mode of evolution of a tumour based on the positions of mutations in high-resolution samples.

    Population codes enable learning from few examples by shaping inductive bias

    Blake Bordelon, Cengiz Pehlevan
    Neural sensory representations impose an inductive bias over the space of learning tasks, allowing some tasks to be learned by a downstream neuron more sample-efficiently than others.

    Spatiotemporal ecological chaos enables gradual evolutionary diversification without niches or tradeoffs

    Aditya Mahadevan, Michael T Pearce, Daniel S Fisher
    Evolution of multiple closely related strains with host-pathogen-like interactions but only one niche and no tradeoffs, can give rise to a spatiotemporally chaotic ecological state that continually diversifies even with generalist mutations that slow the evolution.

    A quantitative modelling approach to zebrafish pigment pattern formation

    Jennifer P Owen, Robert N Kelsh, Christian A Yates
    A mathematical modelling approach to understanding zebrafish stripe pattern formation exemplifies a biological rule-set sufficient to generate wild-type and a diverse range of mutant patterns.

    Dynamics of diffusive cell signaling relays

    Paul B Dieterle, Jiseon Min ... Ariel Amir
    The collective dynamics of cell signaling relays are at once dramatically sensitive to the system dimensionality and insensitive to many biological details.

    A three filament mechanistic model of musculotendon force and impedance

    Matthew Millard, David W Franklin, Walter Herzog
    Benchmark simulations show that the VEXAT muscle model is more accurate than a Hill-type muscle model at mimicking the response of biological muscle to length changes great and small.

    Toward the cellular-scale simulation of motor-driven cytoskeletal assemblies

    Wen Yan, Saad Ansari ... Michael Shelley
    aLENS implements new parallel methods to resolve cytoskeletal assembly dynamics with high stability, physical consistency, and scalability.
