  "textContent": "Scientists at Rice University have produced the first full, dye-free molecular atlas of an Alzheimer’s brain. By combining laser-based imaging with machine learning, they uncovered chemical changes that spread unevenly across the brain and extend beyond amyloid plaques. Key memory regions showed major shifts in cholesterol and energy-related molecules. The findings hint that Alzheimer’s is a whole-brain metabolic disruption—not just a protein problem.",
