Engineered immune cells are getting a new assignment: cleaning up toxic protein buildup in the brain. In aging‑prone mice, customized T cells reduced protein plaques and local inflammation—early evidence that programmable immunity could protect brain health.

Menopause isn’t just about hot flashes—it leaves a molecular fingerprint across the entire female body. 

Gut microbes can signal fat tissue to burn energy. In mice fed a low‑protein diet, specific bacteria triggered conversion of white fat into energy‑burning beige fat—but only when those microbes were present.

Health-related anxiety about aging was linked to faster biological aging. Women who reported greater worry about physical decline showed accelerated epigenetic age based on DNA methylation markers.
