Erythritol, a widely used sugar substitute found in many low-carb and sugar-free products, may not be as harmless as once believed. New research from the University of Colorado Boulder reveals that even small amounts of erythritol can harm brain blood vessel cells, promoting constriction, clotting, and inflammation—all of which may raise the risk of stroke.

Millions of tons of plastic in the ocean aren't floating in plain sight—they're invisible. Scientists have now confirmed that the most abundant form of plastic in the Atlantic is in the form of nanoplastics, smaller than a micrometer. These particles are everywhere: in rain, rivers, and even the air. They may already be infiltrating entire ecosystems, including the human brain, and researchers say prevention—not cleanup—is our only hope. Read more

Dogs trained to detect Parkinson’s disease using scent have shown remarkable accuracy in new research. In a double-blind trial, they identified skin swabs from people with Parkinson’s with up to 80% sensitivity and 98% specificity, even when other health conditions were present. The findings offer hope for a simple, non-invasive diagnostic method using biomarkers that appear long before traditional symptoms, potentially allowing earlier treatment and slowed disease progression.
