Scientists find how “zombie” cells fuel inflammation as we age September 14, 2026
Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflammation and improved healthy aging in mice, suggesting a promising new strategy for fighting age-related decline.
Scientists discover a hidden switch that shuts down inflammation September 13, 2026
Scientists have uncovered a natural braking system that helps the immune system switch off inflammation and prevent harmful immune cells from building up. Boosting this pathway in people reduced inflammation-related immune changes and sped up pain relief, pointing toward potential new treatments for chronic inflammatory diseases.
Ozempic and Wegovy linked to nearly 40% fewer asthma attacks September 9, 2026
Semaglutide, the drug found in Ozempic and Wegovy, was linked to nearly 40% fewer asthma attacks in a large real-world study. It was also associated with about 20% fewer COPD flare-ups. Researchers say GLP-1 drugs may offer respiratory benefits in addition to their effects on diabetes and obesity, but clinical trials are needed to confirm […]
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 […]
