India, April 12 -- Anti-ageing science takes a step forward with scientists now preparing to test a technique that could make old cells behave like younger ones. It offers hope for restoring vision, repairing organs, and possibly slowing down ageing itself. But while the science is promising, experts caution that the risks are just as real.

According to a report published in Nature on April 7, 2026, a new clinical trial, expected to begin soon, will test a method known as partial cellular reprogramming in humans for the first time. The goal is to see whether ageing cells can be safely "refreshed" without losing their identity.

The technique builds on a breakthrough discovery by Shinya Yamanaka, who showed that adult cells can be reprogr...
