His new theories have been heavily criticised by other scientists

A British scientist has claimed that the secret to preventing ageing may be solved in the near future and that some people born already may live for up to a 1,000 years.

The staggering claims were made by Dr Aubrey de Grey, a Harrow and Cambridge-educated biomedical theorist who has made a name for himself for his research into preventing ageing.

Dr de Grey, the co-founder and chief science officer of Strategies for Engineered Negligible Senescence (SENS) Research Foundation, based in California, says he is developing a new form of medicine based on regenerative therapies.

Dr Aubrey de Grey described the human body as being like a is a 'machine with moving parts' and that damage accumulated during its lifetime was part of life.

However Dr de Grey's research team are working on a new type of regenerative therapies. It has been well backed financially with support from leading figures at Google and Paypal.

'By reconstructing the structured order of the living machinery of our tissues, these rejuvenation biotechnologies will restore the normal functioning of the body's cells and essential biomolecules, returning aging tissues to health and bringing back the body's youthful vigor,' the SENS Research Foundation claims.

However the research centres have been criticised by Dr Tilo Kunath, of the Centre for Regenerative Medicine at the University of Edinburgh, has dismissed his theories as incorrect.

Critics say it is only potentially possible to extend a person's life by 30 per cent if they adhere to a restricted diet

Dr Kunath said that no one will be able to live past 120 at present nor will they live longer in the near future.

He claimed it was only potentially possible to extend a person's life by 30 per cent if they adhere to a restricted diet.

'No one in the future could be genetically modified for a human to live longer than say 120 years.
