Isn’t reproducibility the bedrock of the scientific process? Yes, up to a

studies, because the techniques and reagents are sophisticated, time-
consuming and difficult to master. In the past ten years, every paper
published on which I have been senior author has taken between four and six
years to complete, and at times much longer. People in my lab often need... 阅读全帖 |
