Salamanders can heal without scarring. A new discovery about the role their size plays in the process could lead to ways to heal burns without scars.

Masses of spotted salamander eggs are either white or clear. New research indicates two dueling evolutionary forces at work.

The axolotl salamander can regrow lost limbs and parts of its brain or heart. Figuring out its huge genome may pave the way for human tissue regeneration.

Greater understanding of the "'salamander-like' regenerative capacity" in human cartilage could lead to better treatments for osteoarthritis.
