- Scientists Have Identified a New Fossil Species of Axolotl in Mexico
Scientists identified Ambystoma quetzalcoatli, the first fossil salamander in Mexico, showing axolotls have inhabited the country for millions of years.
- Scientists found the “holy grail” gene that could one day help humans regrow limbs
Scientists have discovered a set of genes that could help humans regrow lost limbs by studying axolotls, zebrafish, and mice. The researchers identified powerful SP genes involved in regeneration and used gene therapy to partially restore regeneration in mice. This breakthrough marks a major step toward future treatments that could replace damaged limbs with living tissue instead of prosthetics.
