One immune switch may help drive aging across the body September 3, 2026
Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs, muscles, and memory remain remarkably youthful.
Scientists find why the liver may not heal even after you stop drinking August 31, 2026
Alcohol-related liver disease may trap damaged liver cells in a regenerative limbo, preventing the organ from rebuilding itself even after drinking stops. Researchers linked the problem to inflammation-driven RNA errors and identified a pathway that could potentially be targeted to restore liver repair.
Common supplements rival antibiotics for severe gum disease August 30, 2026
Omega-3 and low-dose aspirin matched the effectiveness of antibiotics in a year-long study of patients with severe gum disease, with both approaches helping about 58% reach the treatment goal. The unexpected result could point to a new way to treat some patients while reducing reliance on antibiotics and the growing problem of antibiotic resistance.
HEPA air purifiers may boost brain function after just one month August 30, 2026
Adults aged 40 and older performed about 12% faster on a test of executive function after using a HEPA air purifier at home for one month. The findings suggest that cleaner indoor air could offer a simple way to help protect the brain from the effects of traffic-related pollution.
A cancer therapy put severe rheumatoid arthritis into remission August 30, 2026
CAR T-cell therapy dramatically reduced disease activity in six people with severe rheumatoid arthritis that had resisted other treatments, with three achieving medication-free remission. The treatment may work by clearing out harmful immune cells and effectively rebooting part of the immune system, although much larger studies are still needed.
Dogs may hold surprising clues to human longevity August 29, 2026
Dogs and humans may have more in common when it comes to aging than scientists realized. Researchers with the Dog Aging Project found that patterns of small molecules in dogs’ blood were linked to longer or shorter lifespans in remarkably similar ways to those seen in people. These metabolic “fingerprints” could offer clues about the […]
A missing color in indoor light may help prevent myopia August 26, 2026
A wavelength of light largely missing from indoor LEDs may play an important role in protecting developing eyes from nearsightedness. Researchers found that indigo light completely prevented myopia in tree shrews, whose eyes share important similarities with human eyes. The discovery raises the possibility that future indoor lighting could be redesigned to more closely mimic […]
Supercharged “natural killer” cells could be a powerful new cancer weapon August 25, 2026
Researchers have found a way to supercharge natural killer cells, powerful immune cells that can attack cancer, so they can penetrate solid tumors and keep fighting once inside. In mice, these specially prepared tissue-resident cells slowed the growth of several tumors, including melanoma and head and neck cancers, and worked even better when paired with […]
This yeast supplement may boost cancer-fighting immunity August 22, 2026
A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting responses against colorectal, skin, and breast cancer cells.
AI may know how you’ll respond to a vaccine before you get it August 21, 2026
AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune readiness” that helped distinguish strong responders from weak ones. Surprisingly, even some healthy people responded poorly, while some immunosuppressed people mounted strong responses.
