For the first time, scientists have used real-time imaging to track tiny pieces of microplastics as they moved through the brain blood vessels of mice. As detailed in a recent paper published in the journal Science Advances, first spotted by The Guardian, they made an alarming discovery: some of the pieces of plastic became stuck, causing more pieces to accumulate behind it much like a "car crash." In experiments, the international team of scientists found that mice that were exposed to microplastic experienced decreased motor function, hinting at the possibility that accumulating plastic may be having negative effects on the […]
