    Structural basis of Ca2+-dependent activation and lipid transport by a TMEM16 scramblase

    Maria E Falzone et al.
    Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.

    Oscillatory phase separation in giant lipid vesicles induced by transmembrane osmotic differentials

    Kamila Oglęcka et al.
    Spontaneous osmoregulation in giant phospholipid vesicles, which is characterized by oscillations in vesicle size and membrane tension, couples to the compositional degrees of freedom at the membrane surface to produce oscillations in domain texture and induce isothermal phase change.
