All information must be fact-checked before it is published by reputable news outlets. Science journals are the most reliable source of information on scientific studies. Scientists who have studied a topic extensively will usually publish their work in these journals. The articles are searchable databases that allow readers to look up study results quickly. Science journals are divided into several categories depending on how recent their publications are and how much money they charge for access to their articles. Open-access journals offer their content freely online and are an excellent resource for scientists who want to spread knowledge about their work. For example, PLOS ONE publishes original research reports that are peer reviewed but does not charge authors for publishing their work. Other options include general science magazines such as Nature and Scientific American and specialized science journals such as Cancer Research and Cell. Reliable information is found in many places. It is important to read more than one source when learning about any topic.
