Scientific writing is a form of communication that allows the clear and precise dissemination of scientific ideas, empirical data, unique theories and concepts, reviews of previous data and new proofs. This is so that other scientists can judge the soundness of the results presented, and in some cases attempt to validate the findings by reproducing the experimental set-up in other labs. Thus any piece of scientific writing in the biomedical sciences must contain enough practical information for the technique to be copied by an appropriately trained person, and for the robustness and ‘believability’ of the results to be ascertained.
