A University of California, Riverside team reports that everyday microplastic exposure sped the buildup of arterial plaque in male—but not female—mice, pointing to possible sex-specific cardiovascular risks and endothelial cell vulnerability. The effects occurred without changes in body weight or cholesterol.
Scientists at Tokyo Metropolitan University have identified polymer-coated fertilizers as a significant source of ocean microplastics, with pathways from farmland directly influencing how much reaches shorelines. Their study reveals that direct drainage from fields to the sea results in far higher beach accumulation than river transport. This work sheds light on the elusive fate of plastics in marine environments.

A new study has found microplastics embedded in human bone tissue, potentially contributing to osteoporosis by disrupting bone health. Researchers detected these particles in all examined samples from middle-aged individuals. The findings highlight growing concerns about plastic pollution's effects on the human body.
