A surprising new weapon against microbes linked to head and neck cancer could be as simple as chewing gum. Scientists developed a bioengineered gum that reduced HPV levels by up to 93% in oral samples from cancer patients and nearly eliminated two harmful bacterial species after a single dose of its extract. Even more promising, the treatment spared beneficial bacteria in the mouth.

New research involving more than 440,000 Americans links cannabis use to increased cardiovascular risk, with occasional users showing 40% higher odds of reporting a history of stroke. The findings suggest that even infrequent marijuana use may warrant concern, although researchers have not established that cannabis directly causes strokes or heart disease.

A major review of more than 350 studies suggests that eating less protein could slow aging, improve metabolic health, and potentially extend lifespan, challenging the widespread belief that more protein is always better. Researchers warn that many sedentary adults may be consuming too much protein, while emphasizing that individual needs depend on age and physical activity.

Scientists have discovered that tumors release natural antioxidants to shut down the immune cells responsible for destroying cancer, exploiting a surprising weakness in the body's defenses. Blocking this mechanism in mice restored immune activity and improved immunotherapy responses, potentially opening a new path toward more effective cancer treatments.

Lewy body dementia (LBD), encompassing Parkinson's disease dementia (PDD) and dementia with Lewy bodies (DLB), is defined by widespread α-synuclein (αSyn) aggregation and frequently exhibits coexistent tau and amyloid-β (Aβ) pathologies. However, whether αSyn pathology is sufficient to drive endogenous tau and Aβ aggregation has remained unclear due to a lack of in vivo models that recapitulate the full spectrum of LBD-associated proteinopathies and neurodegeneration. AIMP2, a parkin substrate...
