Plastic particles from everyday items like Styrofoam cups and take-out containers are finding their way into the brain, where they may trigger Alzheimer’s-like symptoms. New research shows that mice carrying the Alzheimer’s-linked APOE4 gene who consumed microplastics exhibited sex-dependent cognitive decline, mirroring the differences seen in human patients.

Scientists reverse stroke damage with stem cells Scientists in Zurich have shown that stem cell transplants can reverse stroke damage by regenerating neurons, restoring motor functions, and even repairing blood vessels. The breakthrough not only healed mice with stroke-related impairments but also suggested that treatments could soon be adapted for humans, marking a hopeful step toward tackling one of the world’s most devastating conditions.
