La scoperta e stata fatta, involontariamente, da Christian Sommer, uno studente di biologia marina tedesco e appena ventenne. L’aneddoto, che riguarda Ferdinando Boero e Frank Zappa (il primo ha dedicato una medusa al secondo, e il secondo ha dedicato una cazone al primo, per ringraziarlo) potete leggerlo QUI.

The jellyfish can  transform itself back to a polyp, the organism’s earliest stage of life, author Nathaniel Rich writes in The New York Times.
During rejuvenation, it undergoes cellular transdifferentiation, an unusual process by which one type of cell is converted into another — a skin cell into a nerve cell, for instance.
It is possible to imagine a distant future in which most other species of life are extinct but the ocean will consist overwhelmingly of immortal jellyfish, a great gelatin consciousness everlasting.
November 30, 2012 by eldrtas Not only the immortal jellyfish (Turritopsis nutricula) but hydra and many other life forms can reverse their aging, dying only from disease and predation. November 29, 2012 by brendan havel yes it will, they will, they will enjoy environment provided not pollute natural resources as mankind. November 29, 2012 by Gorden Russell If they were self-aware, I bet they’d get bored with life.

About a wide discovery it is invading the world's ocean, swarm by swarm, it transforms from an Adult into a baby.
Turritopsis typically reproduces the old-fashioned way, by the meeting of free-floating sperm and eggs. But when starvation, physical damage, or other crises arise, "instead of sure death, [Turritopsis] transforms all of its existing cells into a younger state," said study author Maria Pia Miglietta, a researcher at Pennsylvania State University.
Through reproduction, the polyp colony can spawn hundreds of genetically identical jellyfish. Miglietta and her colleague Harilaos Lessios of the Smithsonian Tropical Research Institute in Panama compared the DNA of immortal jellyfish from waters off Spain, Italy, Japan, Florida, Panama, and elsewhere for their study, published in the June 2008 issue of the journal Biological Invasions. The pair was surprised to discover that, even though the specimens came from all over the globe, all the genes the scientists looked at were identical. There's no way genetically identical jellyfish swarms could have ended up in so many far-flung places simply by riding ocean currents, Milietta said. For reasons still mysterious, the immortal jellyfish takes on slightly different forms as it spreads.
By studying how exactly the immortal jellyfish's cells do that, he said, scientists may find clues for the struggle against that other silent, rapidly expanding invader. Se vuoi saperne di piu o negare il consenso a tutti o ad alcuni dei suddetti cookies clicca qui.

They are extremely simple organisms, and miRNA are crucial to their biological development. It seems VERY hard to guess breaking technologies and sciences that are not incremental advances. Sommer was conducting research on hydrozoans, small invertebrates that, depending on the stage of life.
The creatures are likely traveling in the ship's ballast water-water sucked into and pumped out of ships to provide stability. Swarms living in tropical waters typically have only 8 tentacles, while those in temperate regions can have 24 or more tentacles.
This may have implications for medicine, particularly the fields of cancer research and longevity. My interests include science (duh!), vegetarian (NOT vegan!) cookery, organic gardening, MMA, and binging on old South Park episodes!
Peterson is now studying microRNAs (miRNAs), tiny strands of genetic material that regulate gene expression.
