Scientific journals are publications that share research findings and advancements in various fields of science. They serve as a platform for scientists and researchers to present their work, allowing others to review, critique, and build upon it. Each journal typically focuses on a specific area, such as biology, physics, or medicine. These journals often use a peer-review process, where experts evaluate submitted articles for quality and accuracy before publication. This ensures that the information is reliable and contributes to the body of knowledge in the respective field. Examples of well-known scientific journals include Nature and The Lancet.
