Popular science news and scientific journals are prone to bias in reporting, either through selecting which articles are published or by exaggerating claims.
By looking at how the information is presented you can often learn a lot about the accuracy of the information itself.
When reading science articles, especially science news in popular magazines or newspapers, you don't have to be a scientist to figure out if it's a well presented scientific study, you just have to be skeptical.
Questions to Ask
If you don't understand any section of an article, look for articles on a similar topic or ask professors for help interpreting the information.
If the article you are reading is in a popular news source the journalist may not have a science background. Newspapers and magazines may also sensationalize science news and alter the orginal meaning of the report. If the article you are reading seems to be unreliable, look for a link to the original paper or search for the scientists' names to find a more reliable article or the original paper.
