Signos Thread
From Star Trek : Freedom's Wiki
The Signos Thread is a genetic abnormity that is caused by an addition enzyme on the host's genetic coding that causes a near complete stop to cellular decay, and near perfection in DNA replication. Due to this a person who is affected by this abnormality will age vastly slower to those that are not effected. Also That person's body would tend to heal better than other of a similar age. This is due to the more efficient operations of the host body at the cellular level.
The Signos Thread was first mentioned in the USS Rosenante Mission Personal Logs
