A small vial containing a sliver of human brain begins to melt with the addition of lye. Over days, this chemical breaks down neurons, leaving behind a gruesome mixture of plastic particles.

Microplastics have been found in nearly every corner of the planet — and now, researchers like Campen are tracking their harmful effects on human health.
