Summary

Not much passes into our brain from the rest of our body, to the chagrin of drug makers everywhere. So it should be cause for concern when a study found that microplastics were somehow ending up in our brain, says chief opinion editor Megha Satyanarayana. She takes a step back and brings us into the wider world of plastics and the way petroleum chemicals can become pollutants far beyond the factories where they are made. Plus, Satyanarayana discusses the Scientific American opinion section and her column Cross Currents, which aims to decode the science from the headlines.
