While cigarette exposures are decreasing for young children, electronic nicotine products are putting toddlers at new risk of inhalation, according to Rutgers Health researchers.
Their study, published in JAMA Network Open, was the first to assess trends in young children’s nicotine exposures across all types of products.
A newly developed bioinformatics tool, MPGK, integrates Mendelian randomization, polygenic risk score, Gene Ontology, and the Kyoto Encyclopedia of Genes and Genomes pathway analyses into a unified command-line workflow. Designed to reduce the learning curve for beginners, MPGK automates complex post-genome-wide association study analyses while maintaining reproducibility and flexibility. Validation using publicly available datasets demonstrated its ability to identify disease associations and biological pathways consistent with prior research.
Cells naturally exchange cytoplasmic components like proteins, RNA, and mitochondria, but scientists lack tools to control such transfers in living cells. Now, researchers in Japan have developed a nanotube membrane-based injector—a system that enables high-efficiency, minimally invasive cytoplasmic transfer between cells. This platform preserves cell viability and can even transfer functional mitochondria, opening new possibilities for cell engineering and regenerative medicine.
An international study published across 34 countries shows that the biological age of the brain can be accelerated or delayed by environmental risk (air pollution, public housing conditions) and protective factors (socioeconomic equality, access to healthcare). The stronger effects arise from interactions among environmental, social, and political conditions. The paper is published today [Friday, 3rd April 2026] in the journal Nature Medicine.
Recent advances in research have focused on immune system variation mainly from a genome perspective. This population-based study (N=1,001 from The Human Phenome Atlas (THPA) cohort) investigated the immune variability from an exposure perspective, and further focused on the roles of the transcriptome and metabolome.
