Inner Life of a Cell

The first time I saw this, I was mesmerized, and then I sat back in awe.  This is an animation created for Harvard's cellular biology students on the inner life of a cell.  One can see how a white blood cell senses its surroundings and responds.  If you have ever been curious just how much really does go on inside the workings of a cell (and we have trillions), then sit back for 8 minutes and enjoy the wonder of it all.  And start thinking about all the little things that can contribute to your cells' health and functioning.
