Just posting to let you all know about Coursera, a collaboration that provides free online courses from several top American universities. They've got one on vaccines run by Paul Offit, which is starting tomorrow, and one on Genomics and Genome technology coming up at some point in the future.

If you are interested in these areas it could be a good investment of time and mental effort.
