Feb. 21, 2026 — Researchers have mapped the genetic risk of hemochromatosis across the UK and Ireland for the first time, uncovering striking hotspots in north-west Ireland and the Outer Hebrides. In some regions, ...

Feb. 21, 2026 — Living at high altitude appears to protect against diabetes, and scientists have finally discovered the reason. When oxygen levels drop, red blood cells switch into a new metabolic mode and absorb large amounts of glucose from the blood. This helps ...

Feb. 21, 2026 — Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, potentially interfering with how they deliver ...

Feb. 21, 2026 — Researchers tested whether generative AI could handle complex medical datasets as well as human experts. In some cases, the AI matched or outperformed teams that had spent months building prediction models. By generating usable analytical code from ...

Feb. 21, 2026 — A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer’s disease. Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell ...

Feb. 20, 2026 — Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In ...

Feb. 20, 2026 — A groundbreaking clinical trial is testing whether specially engineered stem cells can help the brain restore its own dopamine production in people with Parkinson’s disease. Because the condition is driven by the gradual loss of dopamine-producing ...

Feb. 20, 2026 — Breathing polluted air may do more than harm your lungs — it could also increase your risk of Alzheimer’s disease. In a sweeping study of nearly 28 million older Americans, researchers found that ...

Feb. 19, 2026 — A sweeping new study has uncovered a troubling mix of hazardous chemicals in popular hair extensions, including products made from human hair. Researchers detected dozens of substances linked to cancer, hormone disruption, reproductive harm, and ...

Feb. 19, 2026 — A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules ...

Feb. 19, 2026 — A newly discovered bacterial duo may be the hidden cause of chronic constipation. The two microbes break down the colon’s protective mucus layer, leaving stool dry and hard — a problem traditional laxatives don’t fix. Parkinson’s patients, ...

Feb. 19, 2026 — Myopia is skyrocketing around the world, often blamed on endless screen time — but new research suggests the real culprit may be something more subtle. Scientists at SUNY College of Optometry ...
