    Specialized impulse conduction pathway in the alligator heart

    Bjarke Jensen et al.
    A specialized conduction pathway for the electrical impulse in the heart, previously thought to be associated with the endothermic mammals and birds only, is also present in the ectothermic crocodiles.

    The alternative regenerative strategy of bearded dragon unveils the key processes underlying vertebrate tooth renewal

    Lotta Salomies et al.
    Analysis of bearded dragon model reveals a novel tooth replacement strategy that demonstrates the critical importance of epithelial patterning, cell migration, and putative stem cell functional specialization in tissue regeneration.

    Peroxisomal lactate dehydrogenase is generated by translational readthrough in mammals

    Fabian Schueren et al.
    Whole-genome in silico screening for stop codon contexts that produce elevated translational readthrough and peroxisome targeting reveals that in mammals, the amount of lactate dehydrogenase in the peroxisome is controlled by translational readthrough.

    Giant extinct caiman breaks constraint on the axial skeleton of extant crocodylians

    Torsten M Scheyer et al.
    The giant caiman Purussaurus from the Miocene of Venezuela is the first recorded member of crown Crocodylia having three sacrals, thus breaking the otherwise strict vertebral constraint of the group.
