This has already made the rounds of the blogoverse, but it's so cool: video of a leukocyte chasing down and eating a bacterium. I know it's just biochemicals in action, a billion years of evolution writ small. But it's still creepy and amazing. And I learned a new word: this type of white blood cell is called a polymorphonuclear leukocyte, or, for short... a neutrophil. That is so cool! And it will be my new superhero name.
In brightest day, in blackest night, No bacterium shall escape my sight Let those who worship microscopic evil, Beware my power... NEUTROPHIL!
Hmm, that needs work. But not now, for there are microorganisms to ingest! Away!
