Reverse aging

A kind of weird experiment, would probably have been considered cruelty to animals had it not been a primitive/basal jellyfish-like organism, so the RSPCA and the ALF don´t give shit! Still, I suppose the ability to "reverse aging" is...interesting. What a pity it´s only cnidarians, comb jellies and the dog tapeworm (!) that has this unusual ability. 

This sea creature can age in reverse

The next link goes to a Wiki article about "Ming the Mollusk", a quahog clam and the oldest animal ever recorded. Or rather "the oldest individual (non-colonial) animal ever discovered whose age could be precisely determined"Yes, it was 507 years old when it was captured and killed (!) off the Icelandic coast. So this damn mollusc was older than our industrial civilization?!

And if you absolutely want to read Wikipedia´s confusing list of the oldest organisms ever-ever-forever (many considerably more ancient than poor old Ming), you can find it here. I *think* the absolutely oldest living "things" ever were bacterial spores found in New Mexico which were revived after 250 million years. And then there´s the story about the scientist in California who sold "Amber Ale" produced with a 45 million year old revived yeast!

Somehow, I find that hard to believe.
