    Gut bacteria are rarely shared by co-hospitalized premature infants, regardless of necrotizing enterocolitis development

    Tali Raveh-Sadka, Brian C Thomas ... Jillian F Banfield
    Rapid yet comprehensive, genome-resolved analysis of fecal samples from premature infants reveals little overlap in strain composition of gut microbial communities, despite co-hospitalization, and suggests the existence of barriers to strain dispersal.

    Repression of interrupted and intact rDNA by the SUMO pathway in Drosophila melanogaster

    Yicheng Luo, Elena Fefelova ... Alexei A Aravin
    SUMO-dependent pathway is responsible for selective repression of damaged rDNA and silencing of intact surplus units revealing an epigenetic mechanism that controls the differential expression of identical sequences in the same cell.

    Corollary discharge in precerebellar nuclei of sleeping infant rats

    Didhiti Mukherjee, Greta Sokoloff, Mark S Blumberg
    Infant rats distinguish between self- and other-generated movements, and they do so primarily when moving during active sleep.

    Maternal diet-induced obesity during pregnancy alters lipid supply to mouse E18.5 fetuses and changes the cardiac tissue lipidome in a sex-dependent manner

    Lucas C Pantaleão, Isabella Inzani ... Susan E Ozanne
    Maternal obesity alters the fetal cardiac and serum lipidome, promoting early fetal cardiac metabolic maturation, with evidence that the female heart lipidome is more responsive to an in utero obesogenic environment.

    Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

    Calogero Maria Oddo, Stanisa Raspopovic ... Silvestro Micera
    Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.

    Molecular characterization of the intact mouse muscle spindle using a multi-omics approach

    Bavat Bornstein, Lia Heinemann-Yerushalmi ... Elazar Zelzer
    Transcriptomic and proteomic analyses of the murine intact muscle spindle provide comprehensive datasets of its different tissues and identify new tools to study its development and function.

    Asymptomatic Bordetella pertussis infections in a longitudinal cohort of young African infants and their mothers

    Christopher J Gill, Christian E Gunning ... Pejman Rohani
    Longitudinal qPCR-based pertussis surveillance of a low-resource African cohort reveals frequent asymptomatic pertussis infections in both young infants and mothers and suggests possible early warning signals for epidemic outbreaks.

    Infant and adult SCA13 mutations differentially affect Purkinje cell excitability, maturation, and viability in vivo

    Jui-Yi Hsieh, Brittany N Ulrich ... Diane M Papazian
    Electrophysiological analysis and imaging in live zebrafish reveal that infant- and adult-onset SCA13 mutations have distinct effects on the electrical activity, development, and survival of cerebellar Purkinje cells.

    Mother brain is wired for social moments

    Ortal Shimon-Raz, Roy Salomon ... Ruth Feldman
    Mother brain shows special sensitivity to social moments of mother-infant synchrony, compared to other caregiving experiences, through enhanced activation across the caregiving network, response to oxytocin administration, and temporal consistency.
