Nature Structural & Molecular Biology, Published online: 22 May 2026; doi:10.1038/s41594-026-01816-5In this study, the authors use the Caenorhabditis elegans model organism to show that maternal microRNAs are delivered from the intestine to embryos by the yolk, where they regulate gene expression and promote stress resilience in offspring.

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.
