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.
Scientists discover how gut bacteria “train” the intestine to fight inflammation August 21, 2026
A compound made when gut bacteria break down dietary fiber may do more than briefly calm inflammation—it could leave a lasting protective “memory” in the gut. Northwestern Medicine researchers found that butyrate can reprogram intestinal lining cells so they continue encouraging anti-inflammatory immune responses even after the compound is gone. In mice, this effect boosted […]
A little movement in midlife could pay off for your brain years later August 16, 2026
Exercise and healthy blood sugar levels in midlife may help slow cognitive decline decades later. Physical activity appeared especially beneficial for Mexican American adults, suggesting that some brain-protective factors may differ across populations.
Dirty air may trigger painful rheumatoid arthritis flares August 6, 2026
Tiny pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and raise the risk of painful flares, particularly after prolonged exposure. The findings suggest that avoiding poor air quality could become an important part of managing the disease.
A 42-year-old childhood obesity theory may be wrong July 31, 2026
New research challenges the decades-old idea that children experience an “adiposity rebound” when their BMI begins rising around age 6. Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The increase appears to come from growing muscle and lean tissue as children prepare for later […]
Can’t sleep in the heat? These 8 tricks could save your night July 29, 2026
Sleeping well during a heatwave starts with stopping the home from overheating. Close blinds against strong sunlight, ventilate when the air outside becomes cooler, and avoid using heat-producing appliances during the hottest hours. Moving to a cooler room, choosing light bedding and using fans or ice packs safely can also make hot nights more manageable.
Misfolded insulin may be quietly driving diabetes July 28, 2026
Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track. When one key partner was missing, damaged proteins built up and the cells made less insulin. Strengthening this system could offer a new way to protect the pancreas as diabetes progresses.
CRISPR makes prostate cancer vulnerable to immunotherapy July 26, 2026
Scientists used CRISPR to make prostate cancer cells easier for the immune system to detect and destroy. The experimental treatment dramatically improved the effects of immunotherapy in mice and may offer hope for other hard-to-treat tumors.
