Scientists Are Homing In On The Secrets Of Limb Regeneration

Limb regeneration may seem like a science-fiction super power reserved for lizards and starfish, but a new study is helping scientists make more sense of the strange ability.

In research published Wednesday in the journal PLOS One, scientists from Mount Desert Island Biological Laboratory and the University of Maine found that three evolutionary distant species have important similarities in their microRNA -- small RNA molecules that regulate elements of gene expression -- which may be vital to their regenerative abilities.
