It's Okay to Be Smart

If you're not reading It's Okay to Be Smart, a science-themed Tumblr by biology PhD student Joe Hanson, you should get on that. First of all, he blogs like, a million times more often than me. Secondly, he's hilarious. And thirdly, his Tumblr regularly features groovy little bits of science media, like this video about cholesterol.

I loved the shout-out to anterior/posterior embryonic patterning! Really nicely done.
