Microplastics are everywhere — but are they harmful?
AI summary Read the abstract
Microplastics are now found in marine animals and the human body, prompting scientists to urgently investigate their potential health effects. While ubiquity is established, the extent of harm to human health remains an open and actively researched question with significant public health implications.
Scientists are rushing to study the tiny plastic specks that are in marine animals — and in us. Scientists are rushing to study the tiny plastic specks that are in marine animals — and in us.

AI summary Read the abstract
Researchers and science journalists assess the state of evidence on microplastic health risks, noting that tiny plastic particles have been detected even in the human brain, but cautioning that the quality of scientific findings varies widely and that more rigorous research is needed before firm health conclusions can be drawn.
Mind over microplastics — what we still don’t know
AI summary Read the abstract
Microplastics have been detected in human brain tissue for the first time, with higher concentrations found in individuals with dementia, though whether the particles cause neurological damage or simply accumulate more in affected brains remains unknown. The finding opens urgent questions about how microplastics cross the blood-brain barrier and what long-term exposure means for cognitive health.
