Ever wished you could hit the pause button on ageing? At least one creature may do just that. Axolotls seem to halt one of the hallmarks of the process part way through their lives, a finding that could shed new light on ageing and regeneration.
Axolotls (Ambystoma mexicanum) belong to a group of amphibians called salamanders, which are famed for their astonishing powers of regeneration, such as regrowing amputated limbs. They also appear to age very little, a feature called negligible senescence.
