  • Dynamic polarity control by a tunable protein oscillator in bacteria. [Review]
    Curr Opin Cell Biol 2019; 62:54-60Herrou J, Mignot T
  • In bacteria, cell polarization involves the controlled targeting of specific proteins to the poles, defining polar identity and function. How a specific protein is targeted to one pole and what are the processes that facilitate its dynamic relocalization to the opposite pole is still unclear. The Myxococcus xanthus polarization example illustrates how the dynamic and asymmetric localization of po…
  • Plasticity of cell migration resulting from mechanochemical coupling. [Journal Article]
    Elife 2019; 8Cao Y, Ghabache E, Rappel WJ
  • Eukaryotic cells can migrate using different modes, ranging from amoeboid-like, during which actin filled protrusions come and go, to keratocyte-like, characterized by a stable morphology and persistent motion. How cells can switch between these modes is not well understood but waves of signaling events are thought to play an important role in these transitions. Here we present a simple two-compo…
  • The effect of performing versus preparing a task on the subsequent switch cost. [Journal Article]
    Psychol Res 2019Swainson R, Prosser L, … Romanczuk A
  • Behaviour occurs not as isolated incidents, but within an ongoing sequence of events. The task-switching paradigm provides a useful way to investigate the impact of different events upon subsequent performance. An implication of two-stage task-switching models is that preparing a task without performing it might affect task readiness only to a limited extent. However, recent research has surprisi…
