It's been 20 years since a paper in the journal Science showed the environmental accumulation of tiny plastic fragments and fibers. It named the particles "microplastics."

Microplastics can invade the olfactory bulb of the human nose, which transmits smells to the brain, a new study found.

Evidence of microplastics, which are in everything from clothes to water bottles, has been found in human brains, researchers said.

Microplastics continue to be found in some concerning parts of the human body. A new study published Sept. 16 in the JAMA Network Open journal explains how microplastics in the human brain can affect an important part of our daily lives: how we smell.

Microplastics are inescapable. These miniscule plastic particles have been found at ancient archaeological sites, in freshly fallen snow on Antarctica, at the top of Mount Everest and deep in the Mariana Trench.

Our microplastics problem isn't going away. These tiny fragments of plastic pollution have previously shown up in our lungs, in ancient rocks, and in bottled water. A new study reveals the extent to which they're infiltrating the brain,

Scientists in Brazil have found more evidence of microplastics infiltrating the human body. While it has been previously reported that microplastics were found in human brain tissue, this recent study discovered these tiny particles in the olfactory bulbs of the brain which are responsible for processing smells.
