Reliable information can be hard to come by sometimes when trying to understanding how the human body works. You are almost certainly not going to find accurate information in the news/social media. Even scientific journals run into trouble and find themselves having to retract published work for one reason or another. The blog Retraction Watch gives those interested in maintaining the integrity of scientific research the opportunity to keep an eye on what's going on in the research world.
If you're wondering what the relevancy of this is for the autism consider that a case of great significance to anyone with any connection to autism, that of the retraction of a paper by Wakefield, get's a mention in the blog's very first post about why the blog was started in the first place. Consider as well how much grief and angst in the autism community comes about because people don't seem to understand how the scientific process works. Retraction watch is a great opportunity to learn about the scientific process. When the latest news about the latest miracle treatment or the latest causation theory pops up in your news feed or inbox having spent some time studying how the scientific process actually works will help you evaluate said information.
