Salamanders are a biological miracle: they are the only vertebrates that can regenerate entire limbs, a capacity for healing unmatched in the animal kingdom. Lizards can grow new tails, and human children can regrow the tips of their fingers, but only the salamander can cook up perfect shoulders, elbows, wrists and hands from scratch.
And it’s a perfect mystery how they do it. If we only understood how their cells do this wonderful thing, what else would we know about biology and healing? How would it change health care? Our ignorance and our potential are dizzying.
And yet progress has been made: in 2010, researchers reported on a mammalian gene that suppresses regenerative function. When the gene is turned off, presto: animals that couldn’t regenerate suddenly can.
The salamander’s talent is an ideal symbol for what therapists do: for how much there is to learn, and for learning itself, the regeneration of our minds if not our limbs!
The SaveYourself.ca salamander does not believe everything he hears. The salamander is not a sucker. The salamander watches MythBusters. Sometimes the salamander squints at stupid ideas in health care and says, “Meh.”
When something seems too good to be true, the salamander rolls his beady little eyes, heaves a sigh, and gets ready to do brain battle with the forces of the evil Lord Gullible. The salamander is especially irritated by big promises. He is just not that impressed by a lot of expensive therapies.
The salamander is living, breathing proof that there are miracles enough in biology without inventing new ones.
Sometimes you just need to hear sense from a salamander.
Fine, dash my hopes with all your crazy logic and science. Be that way.
Salamanders still win — they are just better at regeneration than anybody else, in every way — but this 2012 news is still really cool: “Biologist discovers mammal with salamander-like regenerative abilities.” The African spiny mouse does a far better job at regenerating than any other known mammal.
