Although often glossed over, the human liver is a pretty amazing organ. Not just because it’s pretty much the sole thing that ...

Axolotls can regrow limbs. Could they one day help us do the same? A better understanding of how these amphibians grow new appendages may lead to better wound healing—or even new limbs—in humans.

Axolotls have a superpower: The adorable, perpetually smiling salamanders have the ability to regrow missing body parts in just a few weeks. Now, in a new study that scientists say could one day ...

For axolotls, it may take only a couple of days to regrow their tiny hands, but in a fully grown human, that process could take years, McCusker said. “It’s important that we continue to do ...

Axolotls, with their signature smiles and pink gills, are the celebrities of the salamander world. But they are more than just cute: They might also hold the secret to regenerating human limbs.

Future technology inspired by axolotls could possibly help humans regenerate limbs—we have what is needed, but need to find out how to make those pieces communicate like they do in axolotls.

When axolotls were given a drug that blocked the breakdown of retinoic acid, their limbs didn't regrow right -- an upper arm would form where a lower arm should be.

With its fascinating ability to regrow entire limbs and internal organs, the Mexican axolotl is the ideal model for studying regeneration. Scientists have now found a factor that tells cells which ...

Salamanders famously have the ability to regrow their limbs, but "one of the outstanding questions that has really plagued the field is how a salamander knows what to grow," said James Monaghan, a ...

Importantly, the work found that retinoic acid helps tell the axolotl which type of limb to regrow. It makes sure the animal doesn’t generate an entire arm when it only needs a hand, for example.

These glow-in-the-dark axolotls can regrow lost limbs — and scientists say studying them could eventually help humans do the same.
