Here and Now is exactly appropriate for this topic. It addresses the most up-to-date state of biology and genetics, although from one man's perspective. This stuff gets me excited. If you do a bit of searching, I'm sure there is a way to listen to the interview given today (2/20/2013) with guest Eric Lander, professor of biology at MIT and science advisor to the president. http://hereandnow.wbur.org/2013/02/20/eric-lander-biology
The FREE course, presented by EdX.org, is March 5th, 2013. Following the link may not work unless you search the main website)
I have never yet used edX, but this looks exciting. 6 to 8 hours a week isn't too hard to committ to, and I am releived, because I was imaging a "live" streaming lecture that I would have to be available for. Also, I worried I might have to buy an expensive textbook.
The materials for study, along with the class, seem to be all freely online, including the main "supplemental" textbook, Molecular Biology of the Cell, 4th edition.
EdX.org also seems to have courses available in quantum mechanics, greek history, justice, and environmental science. I can't find information on how many "students" can take the class. It appears I might receive a "Certificate of Completion" if I pass the class, but I can't find information whether the certificate is free or not.
