The 24th of September is World Cancer Research Day — not to be confused with World Cancer Day, on February 4th. The CNIO will be present on both occasions, with a number of events and encounters pitched towards a mixed public. Not long ago, we partnered with the AXA Foundation, and the Spanish television channel La Sexta organizing a lecture series featuring scientists of renown such as Nobel laureate Harald zu Hausen, who discovered the link between the Human Papiloma Virus (HPV) and cervical cancer, and Elizabeth Blackburn, co-discoverer of the telomerase enzyme.
