Must Be Microplastics on the Brain

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.
