  • Simple amino acid supplement greatly reduces Alzheimer’s damage
    am 21. November 2025 um 16:33

    Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque levels, reduced inflammation, and improved behavior. Its strong safety record and low cost make it a promising repurposing candidate. The findings hint at a surprisingly simple path toward more accessible AD therapies.

  • A drug already in trials may stop chemotherapy nerve damage
    am 21. November 2025 um 16:02

    Researchers discovered that chemotherapy can accidentally trigger a stress alarm in immune cells, causing inflammation that damages nerves. Blocking this alarm protected mice from nerve pain and kept their nerves healthier. A drug already being tested for cancer may help do the same in people. Early blood tests suggest it may even be possible to predict who will develop these symptoms before they happen.

  • New airflow device captures indoor germs before they spread
    am 21. November 2025 um 15:08

    A new airflow device from UBC Okanagan engineers traps exhaled aerosols almost immediately, sharply reducing pathogen exposure in indoor spaces. Early simulations suggest it could outperform existing ventilation systems by a wide margin.

  • This tiny pill could change how we diagnose gut health

    Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to monitor gut disease.

  • Triple therapy sparks a powerful immune attack on leukemia
    am 21. November 2025 um 6:31

    A cutting-edge approach to immunotherapy shows that forcing cancer cells to die through necroptosis can dramatically boost the body's anti-tumor defenses. By combining three existing drugs, scientists reprogrammed malignant B cells so they release danger signals that rally immune cells to fully eliminate leukemia in preclinical models.
