Hydra Loses Immortality When Cold Triggers Sexual Reproduction
The freshwater polyp Hydra oligactis is renowned for its biological immortality, typically reproducing asexually through cloning. However, researchers at the University of Innsbruck have discovered that cold temperatures trigger a shift to sexual reproduction. This transition forces the organism to abandon its immortal state, leading to biological aging and eventual death. The study highlights a significant metabolic shift during this process, specifically noting a sharp decline in taurine levels.
