    Common pneumonia bacterium may fuel Alzheimer’s disease
    21/02/26 06:43:23
    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 death, and the buildup of amyloid-beta—the hallmark protein linked to Alzheimer’s. Higher levels of the bacterium were found in people with Alzheimer’s, especially those carrying the high-risk APOE4 gene, and were tied to more severe cognitive decline.
    Air pollution linked to higher Alzheimer’s risk in 28 million older Americans
    20/02/26 07:47:05
    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 linked to a higher likelihood of developing Alzheimer’s. The connection appeared to stem largely from pollution’s direct effects on the brain, rather than through related health conditions like hypertension or depression.
    Oxford breakthrough could make lithium-ion batteries charge faster and last much longer
    20/02/26 09:18:56
    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 nanoscale and how that affects charging speed and durability. Small manufacturing adjustments reduced internal resistance by up to 40%, potentially unlocking fastcer charging. The technique could help improve both today’s batteries and next-generation designs.
    Scientists uncover oxygen-loving ancestor of all complex life
    20/02/26 07:21:04
    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 oxygen and the other supposedly lived without it? New research suggests the answer lies in ancient microbes called Asgard archaea.
    Scientists find cancer-linked chemicals in popular hair extensions
    20/02/26 05:31:46
    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 immune system effects in nearly every sample tested. Some products contained flame retardants, organotins, and chemicals associated with increased breast cancer risk, and several exceeded European safety thresholds.
