The Inner Life of a Cell

It's not new, but it's quite stunning.

Look at this animated video of the inner structure and processes within a cell. Specifically, the response of a White Blood Cell to an inflammatory agent.

There's another version of this with a commentary explaining the processes and structures involved.

And here's the transcript, by someone who seems to understand this better than I do.

Learning about cells

I found this very good online resource on Amazing Cells. Some very nifty animations & demonstrations.

It's at the Genetic Science Learning Centre at the University of Utah.

Check it out. It gets a bit detailed as  you go along, but the first few modules are cool.
