Gene for tail regeneration in salamanders discovered. When I was in my early teens, I spend some time around an elderly biology professor at Amherst (U. Mass? In Amherst, anyway) who’d spent his entire professional career studying this subject because, he explained to me, if you could unlock the secret of such regeneration, we might one day grow back nerve cells and missing limbs.
He must have died before he achieved success because otherwise I’m sure we’d heard of it by now, but then, he didn’t have the tools to unlock DNA the way we can now.
Wherever he is, I’m sure he’d be pleased by this development.
