A scientific journal is a periodical publication that features research articles, reviews, and studies in various fields of science. These journals serve as platforms for scientists and researchers to share their findings, methodologies, and insights with the global community. Each article is typically peer-reviewed, meaning it is evaluated by experts in the field before publication to ensure quality and credibility. Scientific journals cover a wide range of topics, including biology, chemistry, physics, and medicine. They are essential for advancing knowledge, fostering collaboration, and keeping researchers informed about the latest developments in their areas of interest.
