    Present-day central African forest is a legacy of the 19th century human history

    Julie Morin-Rivat et al.
    The cessation of major anthropogenic disturbances since European colonization in the forests of central Africa leads to a canopy closing, and to the disappearance of certain light-demanding tree species.

    A histone H3K9M mutation traps histone methyltransferase Clr4 to prevent heterochromatin spreading

    Chun-Min Shan et al.
    A lysine-to-methionine mutation in histone H3 dominantly blocks histone H3K9 methylation by trapping its methyltransferase.

    Action history influences subsequent movement via two distinct processes

    Welber Marinovic et al.
    Movement biases due to recent action history involve both dynamically-evolving processes reflecting prediction of future actions, and temporally-stable processes induced by movement repetition.

    Minimal-assumption inference from population-genomic data

    Daniel B Weissman, Oskar Hallatschek
    The coalescent history of a population can be learned just from the present genomic diversity, without having detailed prior knowledge of the pattern of recombination or the forces driving coalescence.

    Environmental deformations dynamically shift the grid cell spatial metric

    Alexandra T Keinath et al.
    When a familiar environment is reshaped, the grid cell spatial code is dynamically anchored to recently encountered boundaries and changes throughout exploration with the specific movement history of the navigator.

    Paternal Effects: Like father, like son

    Claude Becker
    Exposing male mice to nicotine or cocaine enables their male offspring to cope with high doses of either, which suggests that such paternal effects are generic, rather than being a response to a specific type of stress.

    Point of View: Is cell size a spandrel?

    Ariel Amir
    Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.
