Researchers discovered that recurring arthritis triggered by cancer immunotherapy may be driven by immune cells that remember previous attacks and return in a more aggressive state. The findings could pave the way for treatments that prevent painful flare-ups while preserving the immune system's ability to fight cancer.

Scientists have discovered why some people with a high genetic risk of Alzheimer’s remain mentally sharp into their 80s, uncovering a rare mutation that protects the brain from harmful protein buildup. The findings reveal a potential new way to prevent early brain damage and could pave the way for treatments that mimic this natural defense.

Scientists have uncovered a possible explanation for why some people struggle to taste food more than a year after recovering from COVID-19. By examining taste buds from patients with lingering symptoms, researchers discovered molecular abnormalities that weaken the signals responsible for detecting sweet, bitter, and savory flavors.

Walking just 3,000 steps a day could help slow Alzheimer’s-related brain changes, according to new research. Scientists discovered that physical activity was linked to less buildup of harmful tau proteins and nearly half the cognitive and functional decline, even in people already showing early signs of the disease. The strongest benefits appeared at 5,000 to 7,500 daily steps, suggesting that the popular 10,000-step goal may not be necessary.
