The onset of wrinkles, muscle wasting and cataracts has been delayed and even eliminated in mice, say researchers in the US.

It was done by "flushing out" retired cells that had stopped dividing. They accumulate naturally with age.

The scientists believe their findings could eventually "really have an impact" in the care of the elderly.

Experts said the results were "fascinating", but should be taken with a bit of caution.

The study, published in Nature, focused on what are known as "senescent cells". They stop dividing into new cells and have an important role in preventing tumours from progressing.

1. You need to consider what the life span of a mouse is

--a couple of years. If treatments in mice lead to a life span of 4 years, what have you done? Hve you added 2 years (human equivalent 80 + 2 =82), or have you multiplied by 2 (human equivalent 80 x 2 = 160)?
