I will review the book Madness and Memory, which is an amazing first-person account of the trials and tribulations of one scientist who somehow managed to keep getting his research funded, and who continuously did very careful studies despite mass skepticism about his discoveries from other scientists as well as from the lay press.
He would literally call up the editors of the most prestigious journals like Cell and Science and discuss his research results before even submitting an article for publication. (When I was an academic, I had no idea that you could even do that! And I probably wouldn't have gotten away with it anyway). He was also able to manage to find help from academics in several seemingly unrelated disciplines who would be key in his discoveries.
You get feedback from "peer reviewers" of your submitted work than can be absolutely vicious. Dr. P. had to suddenly find new places to house his rodents due to concerns about animal rights activists who were more concerned with rats than people. The press, always looking for a sexy story, quoted his critics to publicly attack him.
Prusiner quotes someone named Maurice Maeterlinck about this type of problem: "At every crossway on the road that leads to the future, tradition has placed, against each of us, then thousand men to guard the past."
