Scientists sequence the genome of a regenerating salamander

The critically endangered Mexican axolotl can regenerate body parts better than practically any other vertebrate on the planet. If a limb is lost, a limb can be regrown.

"We need to figure out why and hopefully mimic that in humans," says Northeastern University's James Monaghan, who studies the biology of regeneration in the salamander species.

What's new: Scientists figured out a way to piece together the axolotl genome and this week reported a nearly complete sequence.
