Targeted uterine mRNA treatment boosts fertility outcomes in mice

Researchers from the Wilmer Eye Institute, Johns Hopkins Medicine Center for Nanomedicine - which designs nanotechnology-based platforms for clinical translation across specialties - developed a strategy for delivering therapeutic messenger RNA (mRNA) to the inner lining of the uterus (endometrium) in mice via modified lipid nanoparticles (LNPs), which are small capsules made of fatty molecules.

Age-related changes in the gut microbiota impair intestinal stem cell function

A new study led by Hartmut Geiger at the University of Ulm, Germany, and Yi Zheng and Kodandaramireddy Nalapareddy, Cincinnati Children's Hospital Medical Center (CCHMC), USA reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.

Ancient ice and modern pollution combine to spread antibiotic resistance as glaciers melt

Glaciers harbor both ancient and human-derived antibiotic resistance genes, preserved in ice and increasingly mobilized by climate-driven melt. This global review proposes a glacier-to-downstream “continuum” to understand how resistance genes may move through connected freshwater ecosystems.
