  1. Electrical stimulation of tissue regeneration in xenopus laevus.

    01 March 2007

    Researchers at the Forstyth Centre for Regenerative and Developmental Biology in Boston, Massachusetts, lead by Dr. Michael Levin have figured out how to trigger tissue regeneration in xenopus tadpoles past the age when they are normally capable of it. After a certain age, the tadpoles are unable to regrow their tails or other organs after amputation, but some nicely nonlinear research shows that it is possible to duplicate the weak electrical field that builds up around sites of major trauma that heralds the regenerative process. This is a phenomenon found in many higher lifeforms, from frogs to deer (the males …
