Which is a journal in which scientists publish original, scholarly research?
Troyanec [42]
The answer is Science. Science is one of the most respected scholary journals where scientists can publish their work after they have written up a manuscript. However, publishing in Science is not easy. Once the authors of a certain proposed paper write it and send it to the editors, the paper itself undergoes a process called double blind peer-review, where their paper is being fact-checked and otherwise scrutinized by multiple researchers of their field in order to maintain a very high quality level of the papers that are being published in Science.
