Basically, science literacy means you have a general ability to find and use information to understand science within a larger context. You are also able to analyze current controversial scientific issues that you see and hear about in the news.
Because scientific literacy does not assume an in-depth knowledge of the scientific concepts or ideas being researched, the best resources will include websites, magazines, and newspapers that popularize scientific information for the general public. You will find below some of the best resources (both academic and general) that offer coverage of science topics for general audiences.
Both of these ebooks suggest related articles in PubMed.
