    The synaptonemal complex has liquid crystalline properties and spatially regulates meiotic recombination factors

    Ofer Rog, Simone Köhler, Abby F Dernburg
    Formation of a phase-separated interface between homologous chromosomes during meiosis enables regulatory signals to spread in cis over long distances, illuminating the longstanding mystery of crossover interference.

    Hydrodynamics and multiscale order in confluent epithelia

    Josep-Maria Armengol-Collado, Livio Nicola Carenza, Luca Giomi
    Confluent cellular layers display the remarkable ability of supportingmultiscale orientational order, that is the existence of different typeof liquid crystal order at different length scales.

    Novel multicellular prokaryote discovered next to an underground stream

    Kouhei Mizuno, Mais Maree ... Kazuya Morikawa
    A new bacterium isolated from an underground stream shows a novel multicellularity by self-organizing its filamentous cells like a liquid crystal and accommodating daughter cells in a sequential manner, which would be a new extant model of prokaryotic multicellularity.

    Mechanical basis and topological routes to cell elimination

    Siavash Monfared, Guruswami Ravichandran ... Amin Doostmohammadi
    Using self-organization, cells can collectively leverage defects in nematic and hexatic orders to localize mechanical stresses and remove an unwanted cell with their preferred path to achieve this explored here by independently tuning cell–cell and cell–substrate adhesion strengths.

    Coupled ion binding and structural transitions along the transport cycle of glutamate transporters

    Grégory Verdon, SeCheol Oh ... Olga Boudker
    Crystal structures of an archaeal homologue of mammalian glutamate transporters in apo and ion-only bound outward- and inward-facing states reveal ion-coupled conformational changes supporting mechanisms of coupling, gating, and transport.
