    Mechanical heterogeneity along single cell-cell junctions is driven by lateral clustering of cadherins during vertebrate axis elongation

    Robert J Huebner et al.
    Very local molecular patterns impart precise changes in the local mechanics of individual cell-cell junctions.

    Kinesin-6 Klp9 orchestrates spindle elongation by regulating microtubule sliding and growth

    Lara Katharina Krüger et al.
    During anaphase B spindle elongation, Klp9 controls the speed of both microtubule sliding and microtubule growth to coordinate the processes and thus maintain spindle stability for faithful chromosome separation.

    Polymerization of misfolded Z alpha-1 antitrypsin protein lowers CX3CR1 expression in human PBMCs

    Srinu Tumpara et al.
    Finding that circulating Z alpha-1 antitrypsin polymers, a feature of ZZ AAT deficiency, lower the expression of CX3CR1 on peripheral blood mononuclear cells encourages more detailed analyses on different circulating misfolded proteins and their role on immune cell surveillance/function.

    R7 photoreceptor axon targeting depends on the relative levels of lost and found expression in R7 and its synaptic partners

    Jessica Douthit et al.
    R7 photoreceptors require the endosomal protein Lost and Found to form stable connections only when this protein is also present in neurons that are synaptic partners of R7.

    Genetic variation, environment and demography intersect to shape Arabidopsis defense metabolite variation across Europe

    Ella Katz et al.
    Measurements of specialized metabolites across a population of 800 natural Arabidopsis thaliana accessions revealed different pressures and evolutionary processes that shaped their variation and distribution across Europe.

    Myoglobin primary structure reveals multiple convergent transitions to semi-aquatic life in the world's smallest mammalian divers

    Kai He et al.
    Ancestral sequence reconstruction of an essential muscle protein involved in O2 storage and transport accurately tracks secondary aquatic transitions in a speciose clade of insectivorous mammals.

    Spatiotemporal control of cell cycle acceleration during axolotl spinal cord regeneration

    Emanuel Cura Costa et al.
    Computational modeling and a cell cycle-reporting axolotl reveal how spinal cord regeneration can be achieved by a signal that propagates 828 μm from the injury site during the first 85 hours post-amputation.

    Tetrahydroxanthohumol, a xanthohumol derivative, attenuates high-fat diet-induced hepatic steatosis by antagonizing PPARγ

    Yang Zhang et al.
    Identifying xanthohumol and its derivatives as PPARγ anatagonists provides new insight into how natural compounds beneficially treat obesity and metabolic syndrome, and provide new compounds for therapeutic development.

    Dwarf open reading frame (DWORF) is a direct activator of the sarcoplasmic reticulum calcium pump SERCA

    M'Lynn E Fisher et al.
    Activation of the sarcoplasmic reticulum calcium pump and enhancement of cellular calcium homeostasis by dwarf open reading frame reveal how this small membrane protein opposes phospholamban inhibitory function in cardiac muscle.

    Repression by the Arabidopsis TOPLESS corepressor requires association with the core mediator complex

    Alexander R Leydon et al.
    The TPL corepressor binds to the core mediator complex through MED21 to inhibit transcription while simultaneously priming repressed genes for rapid reactivation.
