    Arnold tongue entrainment reveals dynamical principles of the embryonic segmentation clock

    Paul Gerald Layague Sanchez, Victoria Mochulska ... Alexander Aulehla
    A microfluidic experimental approach combined with dynamical systems theory reveals how to entrain an embryonic oscillator, the segmentation clock, and allows for the quantification of its entrainment properties.

    Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity

    Onur Ozan Koyluoglu, Yoni Pertzov ... Ila R Fiete
    A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.

    Structures of wild-type and a constitutively closed mutant of connexin26 shed light on channel regulation by CO2

    Deborah H Brotherton, Sarbjit Nijjar ... Alexander David Cameron
    The mutation of Lys125 in connexin26 to glutamate, a carbamylation mimetic, pushes the equilibrium of the gap junction channel seen in cryo-EM towards a more closed conformation.

    On demand expression control of endogenous genes with DExCon, DExogron and LUXon reveals differential dynamics of Rab11 family members

    Jakub Gemperle, Thomas S Harrison ... Patrick T Caswell
    DExCon, LUXon, and DExogron approaches simultaneously block endogenous gene expression and permit tuning of re-expression levels in time and space; proof-of-principle reveals unforeseen differences in protein kinetics, cargo handling, and cell migration regulation between closely related Rab11 family members.
