The Road To Regeneration
Wired is running an interesting article on work to replicate the regenerative powers of amphibians and fish in humans. Zebrafish can regrow lost and damaged body parts to an amazing degree, and the scientist featured in this article is working to turn on the same ability in mammals (and eventually, humans). This research is a fascinating parallel to other reported work on stem cells and regenerative medicine in the past few years. All of these paths offer the hope of longer, healthier lives by boosting our natural abilities to repair age-related damage.
