Good news from the battlefront with Autism: it seems that the scientists found another piece to this puzzle.
The original research paper is a bit hard to read, but it is well worth it, if you care about Autism and the whole vaccine debate:
Common genetic variants on 5p14.1 associate with autism spectrum disorders
Somewhat more digestible version in popular news, from the BBC site:
Genes 'have key role in autism'
Scientists knew for a long time that Autism is most likely NOT caused by vaccines (all those studies... and more studies), but some environmental factors (unknown so far) could still play a role. However, it the genes that make us more susceptible, and the evidence is beginning to surface.
