    Flower-like patterns in multi-species bacterial colonies

    Liyang Xiong et al.
    Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.

    Rod nuclear architecture determines contrast transmission of the retina and behavioral sensitivity in mice

    Kaushikaram Subramanian et al.
    Establishing retinal contrast transmission as a novel determinant of mammalian fitness, this research adds functional significance to a prominent exception of nuclear organization, previously described in nocturnal rod photoreceptor cells.

    Imaging neuropeptide release at synapses with a genetically engineered reporter

    Keke Ding et al.
    A series of genetically-encoded fluorescent reporters that allow imaging of neuropeptide release in vivo, with sub-second temporal and nerve terminal-level spatial resolution are developed.

    Gating and selectivity mechanisms for the lysosomal K+ channel TMEM175

    SeCheol Oh et al.
    Structures of the non-canonical potassium channel TMEM175 in open and closed states reveal unique mechanisms for channel gating and the selective permeation of K+ ions.

    Accelerated viral dynamics in bat cell lines, with implications for zoonotic emergence

    Cara E Brook et al.
    Bats' uniquely robust innate antiviral immune defenses select for faster transmitting viruses likely to generate extreme virulence upon spillover to secondary hosts with immune systems divergent from those of bat.

    The kinesin-5 tail domain directly modulates the mechanochemical cycle of the motor domain for anti-parallel microtubule sliding

    Tatyana Bodrug et al.
    Biochemical, single molecule, cell and structural biology studies reveal an interaction between the kinesin-5 tail and motor domains regulating high-force production, which is critical for microtubule sliding motility.
