Harvard made a great video called The Inner Life of a Cell a couple of years ago using some great computer graphics [hat tip Sadie]. It tells a brief story of the mechanism of inflammation being activated in a leukocyte. It was put to some great music by Studio Daily. I highly recommend you check it out.
If you’re wondering what all that stuff is, you can check out one of Harvard’s versions, which contain a play-by-play. I must admit that (having no real idea of what I was looking at) I got a little bit lost in the video, so Harvard’s version definitely helped clear up a few things. But Sadie and I agree that it’s pretty cool that we can watch a video like that and actually mostly understand it. After spending years studying something like bio, you forget how much you know about it that the average Joe has never even considered.
