- newDental implants can hijack your immune system, scientists discover
Researchers have uncovered a surprising reason dental implant infections often resist antibiotics: the implants themselves can contribute to the problem. Bacteria corrode titanium implants, releasing microscopic particles that hijack immune cells, trigger destructive inflammation, and accelerate jawbone loss.

- newScientists discover a surprising double benefit of exercise for Parkinson’s
A seven-year study found that people with Parkinson’s disease who were more physically active experienced slower declines in memory, thinking, and movement abilities. Those exercising more than eight hours per week showed almost no average cognitive decline, suggesting that staying active may offer important benefits as the disease progresses.

- Millions take fish oil for brain health. A two-year study found no benefit
A surprising two-year clinical trial found that fish oil supplements successfully delivered omega-3s to the brain but failed to improve memory or protect against Alzheimer's-related brain shrinkage. Researchers suspect that getting these nutrients through a healthy diet may offer benefits that supplements alone cannot provide.

- Natural compound could fight rheumatoid arthritis at its source
A natural compound extracted from a medicinal plant has shown surprising promise against rheumatoid arthritis. In rats, it reduced joint swelling, protected cartilage, and calmed the immune responses responsible for chronic inflammation. Scientists discovered that the compound works by targeting a specific protein and restoring balance to fatty acid metabolism, revealing a previously underexplored way to fight the disease.

- A simple 15-minute treatment could help patients avoid carpal tunnel surgery
A simple, steroid-free procedure could offer lasting relief for people struggling with carpal tunnel syndrome, potentially helping them avoid surgery. In a clinical trial involving 63 patients, researchers found that ultrasound-guided hydrodissection, which uses fluid to free a compressed nerve in the wrist, provided longer-lasting improvements in pain, numbness, and hand function than traditional steroid injections.

- Massive study of 460,000 people challenges ultra-processed food cancer fears
A massive study of more than 460,000 Americans found that ultra-processed foods were not associated with increased colorectal cancer risk overall, challenging a widely held assumption. While processed meat was linked to higher cancer incidence, ultra-processed whole grains and dairy products were associated with lower incidence.
