Heading for regeneration: Researchers reactivate head regeneration in regeneration-deficient species of planarians

Rabbits can't do it, neither can frogs, but zebrafish and axolotls can and flatworms are true masters of the craft: regeneration. Why some animals can re-grow lost body parts or organs while others cannot remains a big mystery. And even more intriguing to us regeneration-challenged humans is the question whether one might be able to activate regenerative abilities in species that don't usually regenerate.
