Story summary

Air pollution and wildfire smoke may be more than just environmental hazards; they could be catalysts for Alzheimer's disease. Researchers at Scripps Research discovered that these pollutants trigger S-nitrosylation, which disrupts brain cell connections. Remarkably, blocking this process showed promise in reversing memory loss in both mouse models and human nerve cells, opening doors to potential new treatments.
