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 ...

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 ...

Human language may seem messy and inefficient compared to the ultra-compact strings of ones and zeros used by computers--but our brains actually prefer it that way. New research reveals that while digital-style encoding could theoretically compress . ...

Qubits, the heart of quantum computers, can change performance in fractions of a second -- but until now, scientists couldn't see it happening. Researchers at NBI have built a real-time monitoring system that tracks these rapid fluctuations about 100 ...

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth's mantle rather than its crust. Long debated and notoriously difficult to confirm, these elusive quakes turn out to cluster in regions .. ...

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 .. ...

Oxford researchers have found a way to visualize one of the most hidden -- yet critical -- components inside lithium-ion batteries. By tagging polymer binders with traceable markers, they revealed how these tiny materials are distributed at the ...

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 long term exposure to fine particle air pollution was ...

For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually giving rise to plants, animals, and fungi. But one major puzzle remained: how could these organisms have met if one depended on . ...

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 ...
