"Have scientists found the key to eternal life? Discovery of how to switch off ageing process in worms could lead to mechanism being delayed in humans
* Study of worms found when adult cells abruptly begin their downhill slide
* Researchers say change occurs when they reach reproductive maturity
* Finding is significant because humans have the same genetic 'switch'
* Means scientists could eventually delay ageing and degenerative diseases
Scientists have discovered how to switch off the ageing process in worms - which could eventually lead to the mechanism being delayed in humans.
The study of worms showed adult cells abruptly begin their downhill slide when they reach reproductive maturity.
A genetic switch then allows ageing to begin by 'turning off' certain processes which protect cells within the body.
The finding is significant because humans have the same genetic switch - and means eventually it may be possible to delay ageing and certain degenerative diseases."
