    Proofreading through spatial gradients

    Vahe Galstyan, Kabir Husain ... Rob Phillips
    Theoretical study shows how enzymes can achieve substrate proofreading by taking advantage of existing molecular gradients in the cell while not being endowed with structural features typically required for proofreading.

    Spatial correlations constrain cellular lifespan and pattern formation in corneal epithelium homeostasis

    Lior Strinkovsky, Evgeny Havkin ... Yonatan Savir
    Rejuvenation of corneal epithelium in homeostasis is determined by the interplay between corneal cells replicative lifespan and the spatial correlation between cell replication and cell removal.

    The interplay between asymmetric and symmetric DNA loop extrusion

    Edward J Banigan, Leonid A Mirny
    Models of chromosome compaction by condensins demonstrate that two-sided loop extrusion and long residence times are required for high compaction, suggesting a tight coupling between these two properties in vivo.
