    The universal eukaryotic DNA replication kinetics is the consequence of simple physicochemical rules resulting from the localisation of potential replication origins at discrete sites and the diffusion of limiting origin firing factors in the nuclear space.

    Microtubules soften due to cross-sectional flattening

    Edvin Memet et al.
    A combination of experiments, theory, and simulations shows that the elastic softening of microtubules when they are bent arises due to the flattening of their tubular cross-section.

    Characterisation of molecular motions in cryo-EM single-particle data by multi-body refinement in RELION

    Takanori Nakane et al.
    Multi-body refinement in RELION allows high-resolution reconstruction and visualisation of molecular motions in cryo-EM single-particle data sets with continuous forms of structural heterogeneity.
