New online: Yolk transports miRNAs to embryos and enhances progeny stress resilience
Nature Structural & Molecular Biology, Published online: 27 May 2026; doi:10.1038/s41594-026-01822-7This study shows that yolk, a conserved vehicle for nutrient provisioning to developing eggs, also transports regulatory small RNAs, such as microRNAs, from somatic tissues to the germline and embryos. This pathway links the maternal environment to inherited regulatory information and stress resilience in the next generation.
