    A distinct tethering step is vital for vacuole membrane fusion

    Michael Zick, William T Wickner
    Rigorous assays of membrane fusion show that a distinct tethering step is required for lumenal compartment mixing in a manner that extends beyond simply increasing the amount of total trans-SNARE complex.

    Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion

    Jiajie Diao et al.
    A combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.

    The SNAP-25 linker supports fusion intermediates by local lipid interactions

    Ahmed Shaaban et al.
    The SNAP-25 linker acts as a functional component of SNARE complexes, initially facilitating SNARE interactions and later promoting fusion triggering and pore evolution by local membrane contacts.

    Mechanical force induces mitochondrial fission

    Sebastian Carsten Johannes Helle et al.
    Mechanically stimulating mitochondria causes them to divide via the recruitment of the mitochondrial fission machinery to the mechanically strained site, showing that intracellular organelles can be mechanoresponsive.

    Detailed analysis of chick optic fissure closure reveals Netrin-1 as an essential mediator of epithelial fusion

    Holly Hardy et al.
    Chick optic fissure closure is a powerful new model system for epithelial fusion and has revealed Netrin-1 as a conserved and essential mediator of tissue fusion in multiple contexts.

    Dilation of fusion pores by crowding of SNARE proteins

    Zhenyong Wu et al.
    A few SNARE complexes suffice to fuse membranes, but many more are needed to dilate the nascent fusion pore by molecular crowding for efficient neurotransmitter or hormone release during exocytosis.

    A new motor synergy that serves the needs of oculomotor and eye lid systems while keeping the downtime of vision minimal

    Mohammad Farhan Khazali et al.
    Involuntary eye movements that keep images positioned over the center of the retina are synchronized with blinks to minimize disruption to vision.
