Year of great discovery/work

The medium Dulbecco created supported cell growth, so that the cells would be healthy and could subsequently be infected with viruses such as polio and hepatitis. To this day a medium known as Dulbecco’s Modified Eagle’s Medium is available commercially. Later in his career, Dulbecco focused on the connection between viruses and cancer. His studies showed that some viruses insert their genetic material into cells causing them to reproduce uncontrollably and cause cancer. For this discovery, he shared a Nobel Prize in 1975.
