From a nail-bitingly tense chase sequence all the way to a seemingly impossible run down an all too narrow alleyway, this video of a ridiculously-dogged white blood cell in hot pursuit of some fleeing bacteria is a master class in suspense done right.

The video sequence above depicts a neutrophil dodging through a path of red blood cells to catch up some Staphylococcus aureus that had only just been added by researchers as they filmed. Though it wouldn't be widely seen until decades later, the footage dates all the way back to the '50s when it was actually taken by Dr. David Rogers, who would later go on to chair the National Commission on AIDS, but at the time was researching infectious diseases at Vanderbilt University.
