Alterung

Researchers at Emory University have discovered that excessive brain and muscle activity during minor balance disruptions contributes to poorer balance recovery in older adults, including those with Parkinson's disease. The study, published in eNeuro, reveals that trying harder to balance may actually increase fall risk. Opposing muscles stiffening simultaneously further impairs stability.

Researchers at UCLA have identified a protein that slows muscle repair in aging but enhances cell survival in mice. Blocking the protein improved healing speed in older mice, though it reduced long-term stem cell resilience. The findings suggest aging involves survival strategies rather than mere decline.

A comprehensive review in Beverage Plant Research concludes that evidence from human studies most strongly supports an association between tea consumption—particularly green tea—and lower risks of cardiovascular disease, obesity, type 2 diabetes and some cancers, while calling evidence for brain and muscle benefits “promising” but less settled. The authors also caution that bottled and bubble tea products, which can include added sugar and other additives, may blunt tea’s potential advantages.
