CHICAGO : Scientists in Spain have unlocked the genetic code of the immortal jellyfish - a creature capable of repeatedly reverting into a juvenile state - in hopes of unearthing the secret to their unique longevity, and find new clues to human aging.
Like other types of jellyfish, the T. dohrnii goes through a two-part life cycle, living on the sea floor during an asexual phase, where its chief role is to stay alive during times of food scarcity. When conditions are right, jellyfish reproduce sexually. "We've known about this species being able to do a little evolutionary trickery for maybe 15-20 years," said Monty Graham, a jellyfish expert and director of the Florida Institute of Oceanography, who was not involved in the research.
The study was aimed at understanding what made this jellyfish different by comparing the genetic sequence of T. dohrnii to that of Turritopsis rubra, a close genetic cousin that lacks the ability to rejuvenate after sexual reproduction.
