Hydra loses its immortality after cold triggers switch to sexual reproduction
The Hydra polyp, known for its ability to clone itself and live indefinitely, has a surprising weakness: it ages and dies when exposed to cold temperatures. When this happens, the animal switches from cloning to sexual reproduction. This process is accompanied by a drop in taurine levels.
Why it's good news: This good news is significant because it shows that even in nature's most resilient creatures, there are limits to their immortality, giving scientists new insights into aging and reproduction.
