I would like to share a good resource on bio-medical writing. The resource is an online course in writing. It is intended primarily to help researchers write and publish biomedical papers in English. However, much of the advice also applies to writing papers in other fields and languages.
The course consists of text to read. Thus, it resembles a short textbook. It has 6 sections, with the following titles:
Scientific writing style
Prewriting stage
Basic composition of a biomedical paper
Publishing
Correct usage of English
Technical and grammatical points
