Senescent zombie cells refuse to die and secrete inflammatory factors that accelerate aging and chronic diseases. New therapies called senolytics can eliminate these cells, potentially extending healthy lifespan and preventing conditions from arthritis to neurodegeneration.
NAD+ precursors like NR and NMN offer a practical way to boost cellular health and extend healthspan by mimicking calorie restriction's benefits without dietary changes, though long-term safety data is still emerging.
Age-reversal technologies including telomere extension, senolytics, and regenerative medicine are transitioning from labs to trials, promising extended lifespans that could fundamentally reshape economies, healthcare, and society—but raising urgent questions about equity and access.
Senolytic drugs selectively eliminate zombie cells that accumulate with age, showing breakthrough results in human trials for cancer treatment and metabolic health.
