Scientists could be soon be able to slow or even reverse the ageing process, it is believed.

But, as great minds slowly unlock the secrets of ageing, questions will inevitably arise over the dangers and ethics of meddling with nature and out biological clocks.

Some fear such treatments could fuel cancer risks, while others point to the problems it will create in terms of the already burgeoning population and the 'pension time bomb' in the West.

Progress is now being made on the complex ageing process, which has long been surrounded in mystery.

The reversing of the ageing process in mice was detailed by a team at the Dana-Farber Cancer Institute in Boston in a Nature paper, which was published last year.

Chromosomes that are based inside the nuclei of all cells were targeted, in particular telomeres, which are caps at the tips of chromosomes.

Telomeres play the role of protecting chromosomes from damage, but over time they shorten, until the cells can no longer replicate.

The team, led by Professor Ronald DePinho, manipulated the enzyme that regulates these tips and saw dramatic results unfold. The biological clock of the mice appeared to reverse when the enzyme was reversed.

Should successful anti-ageing medical treatments be developed, access will soon become a key issue, according to Professor James Goodwin, who leads the research team at Age UK.

'Later life should be an enjoyable time where people can see more of their friends and family, pursue existing and new hobbies and generally make the most of life. Unfortunately for many people, later life can be marred by ill health, with men and women expected to live over 7 and 9 years of their lives with a disability respectively.

'The research into Telomeres is an intriguing and immensely valuable breakthrough that will develop our understanding of ageing. Only by understanding the ageing process, and why some people age-well and others do not, can we hope to develop preventions, treatments and hopefully cures for illnesses that are associated with ageing. Ultimately the aim of ageing research isn’t simply to try and extend the years in our life, but the life in our years, so that we can all live long and most importantly, healthy lives.'

What's your opinion on all this, David?
