Sci is at Neurotic Physiology today, talking about http://scientopia.org/blogs/scicurious/2013/01/04/friday-weird-science-the-good-old-book-smell/. You know that smell, and you may even love it. But what causes it? And can you buy the perfume? Head over and check it out!

And in case you missed it from earlier this week, at Neurotic Physiology on Wednesday I talked a little about MOOCs. Are these massive open online courses all they are cracked up to be? What should they be? Have you taken one? What did you get out of it? I want to know! Head over and tell me about it.
