What does that even mean, Michael: "it can reverse its current age to a younger age and start aging again"?
Whoever reported, or published, this research, how is age being defined & determined, and how is "reverse its current age to a younger age" being defined & determined?
If that just means an acceleration in free radical elimination, or a slowing in replacement of cells, I most decidedly would not define that as "reversing its current age".
Also if injured jelly fish... live longer, or regains the ability to mate again (or however they are defining 'younger age'), I wouldn't call that "reversing to a younger age".
My current understanding is aging is in the genes, and not in wear-and-tear... which seems obvious now that we know humans replace every cell in the body every seven years, and the fact that life spans among different species of similar sizes and forms have drastically different lifespans. It's never been announced an aging gene has been found, let along understood, so I highly doubt actual reverse aging can be determined in jellyfish.
