In 2001, Victor Ambros received an email asking him to review two studies on microRNAs. He had previously discovered these genetic molecules in C. elegans roundworms with his wife Rosalind Lee, believing them to be unique to this species. However, a collaborator found microRNAs in various animals, indicating they were widespread. Ambros and Lee discovered more microRNAs and were excited about their research until receiving the email. This marked a turning point in their work, prompting them to delve deeper into the study of microRNAs. The discovery of these molecules revolutionized the field of genetics and molecular biology.
