After a viral hot-mic exchange between Xi Jinping and Vladimir Putin about living to 150, a Chinese biotech start-up says it’s working to make that dream real. Lonvi Biosciences is developing anti-ageing pills that target so-called “zombie cells,” using a compound derived from grapeseed extract called Procyanidin C1. The firm claims its drug extended the lifespan of mice in experiments by destroying aged cells and protecting healthy ones. Lonvi says that with proper lifestyle and medical care, its treatment could help humans live up to 120 years, sparking renewed debate on China’s race toward longevity science.
