    Neurogenic decisions require a cell cycle independent function of the CDC25B phosphatase

    Frédéric Bonnet, Angie Molina ... Eric Agius
    The cell cycle phosphatase CDC25B controls cell cycle progression and neurogenesis through independent pathways.

    Differential methylation between ethnic sub-groups reflects the effect of genetic ancestry and environmental exposures

    Joshua M Galanter, Christopher R Gignoux ... Noah Zaitlen
    An epigenome-wide study shows that ethnic self-identification and genetically determined ancestry both make important independent contributions to DNA methylation levels.

    Synthetic analysis of trophic diversity and evolution in Enantiornithes with new insights from Bohaiornithidae

    Case Vincent Miller, Jen A Bright ... Michael Pittman
    Enantiornithine birds reached similar dietary diversity to modern birds in a similar amount of time many millions of years earlier, but how exactly they did that requires further research.

    Coding of latent variables in sensory, parietal, and frontal cortices during closed-loop virtual navigation

    Jean-Paul Noel, Edoardo Balzani ... Dora E Angelaki
    Primates use their eyes to keep track of spatial goals, and this strategy is reflected by the functional connectivity between a traditionally considered optic flow area (dorsomedial superior temporal area) and prefrontal cortex.

    Absent phasing of respiratory and locomotor rhythms in running mice

    Coralie Hérent, Séverine Diem ... Julien Bouvier
    When mice run, their breathing frequency increases but breaths are not temporally synchronized to strides at any speed or gait.

    Ancient viral genomes reveal introduction of human pathogenic viruses into Mexico during the transatlantic slave trade

    Axel A Guzmán-Solís, Viridiana Villa-Islas ... María C Ávila Arcos
    The characterization of ancient B19V and HBV genotype A4 viruses circulating during Colonial epidemics provides new insights into the pathogens that were introduced to the Americas after the European colonization.

    A new Heterodontosaurus specimen elucidates the unique ventilatory macroevolution of ornithischian dinosaurs

    Viktor J Radermacher, Vincent Fernandez ... Jonah N Choiniere
    A new specimen of Heterodontosaurus elucidates how ornithischian dinosaurs evolved a body plan substantially different from that of other dinosaurs and what these differences meant for their breathing.

    Molecular shifts in limb identity underlie development of feathered feet in two domestic avian species

    Eric T Domyan, Zev Kronenberg ... Michael D Shapiro
    Feathered feet of pigeons and chickens result from a partial molecular and morphological transformation of legs to a wing-like identity.
