Microplastics Turn Water Into a Reactive Chemistry Engine, Lab Study Finds

A Columbia University-led team has found that water touching microplastic surfaces can spontaneously produce hydroxyl radicals—highly reactive oxygen species capable of damaging proteins and cell membranes. The peer-reviewed paper challenges the assumption that plastic debris is chemically inert and harms health mainly through physical accumulation. The experiments were laboratory-only, not in living organisms. Core finding: … Read more

Penn State Lab Tests Hint Recycled-Plastic Roads Wear Down More Slowly

Blending road pavement with recycled plastic packaging waste has long tempted engineers with a double promise: a destination for hard-to-recycle material and longer-lasting highways. Fresh laboratory work from a Penn State-led research team now adds evidence to that case — while also flagging a measurement problem that could complicate how such pavements are judged in … Read more
