Secrets of the immortal jellyfish

Could the secret to immortality be found within a particularly unusual species of jellyfish ?

German marine-biology student Christian Sommer had been researching small aquatic invertebrates off the cliffs of Portofino when he came upon an interesting and obscure species known as Turritopsis dohrnii. After spending time studying the specimens, Sommer started to realise that what he had found was something rather special. The strange creatures appeared to age in reverse, becoming younger and younger before repeating their life cycle over again.

Scientists would later describe this process as similar to a butterfly that turns back in to a caterpillar or even a chicken that turns back in to an egg before hatching again. In short, the species never dies - it just repeats its life cycle over and over. What Sommers had discovered was a form of life that could legitimately lay claim to the term 'immortal'.

"After several days he noticed that his Turritopsis dohrnii was behaving in a very peculiar manner, for which he could hypothesize no earthly explanation."

If you open a New York Times this weekend, you'll find a story about jellyfish and immortality splashed across the cover of the Sunday magazine.The 6,500-word narrative is a compelling read, but a critic at the Knight Science Journalism program at MIT urges skepticism. "...the problem with this story is that much of what is reported is highly improbable, even unbelievable," writesPaul Raeburn. "And the writing is discursive to a fault." The author, novelist Nathaniel Rich, traveled to Japan to meet a scientist who thinks that an organism known asTurritopsis dohrnii may unlock the secret to hum... [More]

Jellyfish can never been fully understood, so in my view this is still open as space. We don't know everything, he jealous that someone else claimed it first

What happens if something eats the jellyfish?

What happens if something eats the jellyfish? Probably not a good idea. One could easily die, I suppose. Especially if it includes their poison tenticles. Not sure about the main body though. Besides which, ingestion of long-lived species apparently does not transfer their longevity to the "eater" anyway.

Estradiol activates your telemeres lengthening mechanisms. Its found in milk, beans, soya and some other foods. Its also found in many contraceptive pills and levels are higher in women than in men (thats why they live longer). I recommend a pint of whole milk per day for the rest of y... [More]
