Inside the Cell
Animations showing the inner workings of a living cell often look mechanistic, almost like a little assembly line. The reality is quite different. Cells are just packed full of proteins and near random activity. Science writer Carl Zimmer described it as “barely constrained randomness.” The BioVisions group at Harvard have put together this update to their previous Inside the Cell video to let you see what it is really like.
