The dream of reversing aging has captivated humans for centuries, and today science is closer than it ever has been to achieving that goal. Which is to say: It’s still pretty far away.
That’s not for lack of trying. Some researchers are attempting to reprogram cells to make them biologically younger, which has been shown to reverse features of aging in older animals.
Unfortunately, this can also induce cancer. Other researchers are studying drugs called senolytics, which aim to clear aging cells out of the body. However, they can also destroy other cells humans need to survive.
