Axolotls can regrow lost limbs - always in the perfect size. Scientists from Dresden have now deciphered how this works. Their mathematical model shows that two messenger substances work together as an intelligent measuring system. The findings could also be important for us humans.

A rhythmic alternation between solid and liquid states inside the cell enables division over several cycles. The discovery changes our understanding of one of the most fundamental processes of life.
