Research experiments usually give too many results, making writing research article very difficult and unfocussed. ‘Never start writing any sentence of a research article without knowing clearly the main message’. I invented the Micro-Article to select the major, novel result - and thus the main message - before writing a full research article. Start by designing a simple figure that conveys the novel message. Then fill in result description, interpretation, novelty and benefits. Then fill in problems and hypothesis. Then design a title conveying the novelty or advance, using both specialists and general words, as the title should be readable by a PhD in a different discipline. Share your Micro-Article with scientists in your field (lab colleagues), scientists outside your field and friends: analyze their questions. Then, once the novel message is clear in your mind, start writing your research article. The Micro-Article can be used for scientific writing workshops.
