The cure for cancer.

[Nikia]

7. I agree especially with your first point

I went to college with a very strong biology program. There was a very high percentage of students who were going on to medical or graduate school. There were a number of students who dreamed of curing cancers. Some of them had personal reasons, like a friend or relative that died of cancer. Others were out for the fame and fortune. I remember a discussion where they were sure that doing that would win a Nobel Prize.
If any of those classmates discovered the cure, I doubt that they would suppress it.
