    C1 neurons are part of the circuitry that recruits active expiration in response to the activation of peripheral chemoreceptors

    Milene R Malheiros-Lima et al.
    An unbiased description reveals potential implications for understanding the developmental mechanisms that match respiratory supply and demand during hypoxia.

    First bone-cracking dog coprolites provide new insight into bone consumption in Borophagus and their unique ecological niche

    Xiaoming Wang et al.
    Fossilized feces (coprolites) of extinct bone-crushing dogs, Borophagus parvus, from late Miocene (6 million years ago) of California demonstrates consumption and preservation of bones in digestive tracts and potential social hunting behavior by these predators.

    New footprints from Laetoli (Tanzania) provide evidence for marked body size variation in early hominins

    Fidelis T Masao et al.
    Bipedal footprints made 3.66 million years ago provide the clearest available evidence to date of the occurrence of marked body size variation in Australopithecus afarensis..

    Chronic ethanol consumption compromises neutrophil function in acute pulmonary Aspergillus fumigatus infection

    Nathalia Luisa Sousa de Oliveira Malacco et al.
    Cell biology analysis demonstrated for the first time the effect of chronic ethanol consumption in neutrophil impaired migration by CXCR2 downregulation and neutrophil function during acute Aspergillus fumigatus infection.

    Sex-dependent effects of in utero cannabinoid exposure on cortical function

    Anissa Bara et al.
    Adult male, but not female, rats showed altered neuronal function, inhibited synaptic plasticity and diminished social behavior following cannabinoid exposure during gestation in a model of cannabis use during pregnancy.

    Purinergic regulation of vascular tone in the retrotrapezoid nucleus is specialized to support the drive to breathe

    Virginia E Hawkins et al.
    CO2/H+-dependent purinergic signaling by astrocytes provides specialized control of vascular tone in a brainstem respiratory center in a manner that contributes to respiratory behavior.

    Precise base editing for the in vivo study of developmental signaling and human pathologies in zebrafish

    Marion Rosello et al.
    Base editors, with improved specificity and expanded PAM sequence recognition, can be used in zebrafish for the rapid and efficient introduction of single base pair mutations.

    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.

    Preliminary paleohistological observations of the StW 573 (‘Little Foot’) skull

    Amélie Beaudet et al.
    Virtual investigation of the 3.67-million-year-old skull of 'Little Foot' using synchrotron radiation reveals histological details of Australopithecus dental and bone tissues.

    Homo naledi and Pleistocene hominin evolution in subequatorial Africa

    Lee R Berger et al.
    A late Middle Pleistocene age for Homo naledi demonstrates a diversity of hominin species in Africa at this critical time in the archaeological record.
