Yet another nicely done TED presentation, which show animations of biology and DNA. Check it out!  I wish they have the long version that walkthrough all the animations and explain how things work.

We have no ways to directly observe molecules and what they do — Drew Berry wants to change that. At TEDxSydney he shows his scientifically accurate (and entertaining!) animations that help researchers see unseeable processes within our own cells.
