One good way to self-educate on medical research in general is to read the Science-Based Medicine group blog

regularly. My single favorite link to share in a Hacker News comment is the article "Warning Signs in Experimental Design and Interpretation" by Peter Norvig, director of research at Google, on how to interpret scientific research.

Check each news story you read for how many of the important issues in interpreting research are NOT discussed in the story.
