Prejudice in science - Lessons from the coronavirus story

In the current pandemic times, medical physicists may not be aware that there is an interesting story on two significant discoveries related to the coronavirus. One is the invention of the polymerase chain reaction (PCR) and the other is the first electron microscopic observation and identification of the coronavirus. Both of them were disregarded by the reviewers and major journals declined to publish these discoveries. These days, PCR, for example, is a widespread method for analyzing DNA, having a profound effect on healthcare, especially now during the Covid-19 pandemic. Prejudice or perhaps ignorance prevail in every aspect of our society, and there is no exception in scientific research. We need to, however, learn from these two stories and be open-minded about novel discoveries and findings - as they may be just disruptive in the "right" way to lead to an unexpected breakthrough.
