A time-course of single nuclei RNA-seq of the mouse placenta identifies trophoblast subtypes and the genes, signaling events, and transcriptional networks important for their differentiation, maintenance, and function.

When real ants confront the classical 'Ant-in-a-labyrinth' physics problem where a random walker traverses a percolated environment, they employ active extended sensing and collective cognition to outperform passive physical solutions.

Mice exploring a labyrinth freely for the first time learn a complex action sequence after a handful of rewards, exhibiting a learning rate 1000-fold higher than in commonly-used paradigms.

Cranial endocasts of fossil and extant lungfish, analysed via tomography and novel principle component analyses designed for use with missing data, show that lungfish forebrain and inner ear regions show the most variation in brain shape evolution through time.

Computed tomography data reveal large and adult-looking inner ears in very young individuals of the long-necked dinosaur Europasaurus holgeri suggesting precociality in this dwarfed island dweller from the Late Jurassic of Germany.

Expression of Bisphosphoglycerate mutase, a key enzyme affecting the release of oxygen from hemoglobin, is augmented in the murine placenta challenged by gestational hypoxia in mice while its expression is attenuated in placenta of human FGR.

The morphology of the inner ear distinguishes major anthropoid clades and enables the proposal of various shared-derived features for apes as a whole, lesser apes, and great apes and humans.

Growth-delayed offspring generated from eggs that lacked normal epigenetic programming exhibited a remarkable capacity to undergo late gestational fetal growth recovery, despite inefficient placental function.

Cuticulosomes are organelles found in the hair cells of birds that are composed of ferritin nanoparticles, form rapidly after hatching by the fusion of vesicular structures, and may play an indirect role in magnetic sensation.

Imprinted gene expression is set up during a critical window of early embryonic development, by the translation of parental imprints by oocyte-supplied Smchd1 into allele-specific gene silencing.
