Our brains are increasingly plastic. Minuscule shards and flakes of polymers are surprisingly abundant in brain tissue, a study of postmortem brains shows.
This appraisal of microplastics and nanoplastics, published February 3 in Nature Medicine, raises questions and worries about what this plastic is doing to us.
“The findings are both significant and concerning,” says Raffaele Marfella, a cardiovascular researcher at University of Campania “Luigi Vanvitelli” in Naples, Italy. He and colleagues recently found that people with more micro- and nanoplastics, or MNPs for short, in blood vessel plaques were at higher risk of heart attacks, strokes and death.
