This is really neat stuff, @suesa. I learned about cells in biology class and I knew they were "alive," obviously... but I never really paid attention to them. Every now and then I realise they exist, and I'm made up of them.
I also never realised their activity could be this animated-- as you said, I think of cells and imagine them as mostly either stationary or moving along in the bloodstream. Instead, those are real, tiny things committing genocide of sorts on other tiny things... inside me! I can't think about it for too long or I'll go crazy.
Thanks for teaching me something new today. Your science posts are one of my favourite things on Steemit.
