- The 'head activator' was a molecule believed to be crucial for head regeneration in hydra, discovered by H. 'Chica' Schaller in 1973.
- Chica's work gained significant attention in developmental biology, but her findings were difficult to replicate, leading to skepticism and eventual rejection by the scientific community.
- Tensions between Chica and Werner Müller, a fellow biologist, escalated into accusations of fraud, a university senate hearing, and lasting professional and personal consequences for both.
- Advances in genetics and the sequencing of the hydra genome in 2010 provided conclusive evidence against the existence of the head activator in hydra, undermining Chica's claims.
- The story highlights the human and institutional costs of irreproducible science, as well as the personal and professional conflicts that can arise in academic research.
