@wonderofscience finish him!
(And also, very cool to see)

@wonderofscience

Finally...I mean srsly, dude! Step up your game a bit or it would have escaped!

@wonderofscience haha someone put the Benny Hill theme on it please ^^
@wonderofscience Is it not a wonder how little battles are waged every day in our bodies? Nature ever daunts all!

@learningbreezeofficial @wonderofscience the white blood cell is the animal and the human is the environment made of older dead or dying ancestors.

That little animal has the complete set of human genes, unlike the blood cells nearby which are nearly empty shells. It will encounter a trigger, settle itself in a place where needed, and become a stem cell that can bud off any cell type that is deficient in the local area.

Thus it switches from predator to environment, controlling both directly.

@Urban_Hermit @wonderofscience that’s such an interesting take! I mean, the thought of white blood cells going from being these fierce little predators to just chilling out and becoming part of the environment? Mind-blowing, right? It really shows how our bodies are like this crazy, finely-tuned machine. So much balance and adaptability happening all the time!

@learningbreezeofficial @wonderofscience it is factually correct while everything else about biology remains factually correct. Someday the paradigm will shift, and this idea, that the organism is an environment generated by the micro organism, will open up whole new ways of thinking about organisation.

And all because one day a tide pool scummed over and the little amebas had the genes to make their environment better as a semi closed system, and even the dead or dying had a role to play.

@learningbreezeofficial @wonderofscience thanks for bringing me back to this.

Another great observation: That little ameboid, the white blood cell, is so very much a predator, yet in these moments it doesn't pursue those bacteria to satisfy hunger. There is no scarcity, it is bathing in the perfect nutrient solution. But in exchange it uses all the tools of its ancient predatory ancestors to ruthlessly pursue threats to that environment and its future self because they share the same fate.

@learningbreezeofficial @wonderofscience it would be perfect symbiosis between organism and environment, except there is no distinction between the two, they all share the same genes, they are only activating different parts of the same unified code to pursue their currently individual purposes. But that guy yet carries the future potential to be every single thing in his support network. And he relentlessly does this job, potentially to death, to support the possibility of doing the next.
@learningbreezeofficial @wonderofscience while it is not without mistakes, it is the pursuit of perfection.
@Urban_Hermit that’s quite poetic.
@wonderofscience
Almost excacly how they made it in Once upon a time 🙃
@ekeshkekesh @wonderofscience I loved this anime.
It's not totally scientifically accurate, and some jokes were a little bit edgy by today's standard, but it was such a good introduction to understanding our body.

@wonderofscience

I had seen a similar one quite a while ago and it filled me with joy, and I am again now. It's amazing, it's beautiful, it's part of the body, it's like this separate entity that lives inside you.
I feel a human (and other animals) are a total of multiple organisms, all working together to create the shape we have. The more organisms, the bigger and more complex the creature.

@wonderofscience One of the two escaped though
@wonderofscience We are a collective--not a single organism. A tightly integrated colony of almost genetically identical cells interacting together with cells of hundreds of other species.

@wonderofscience

I wonder what the structure at the other end of the white cell is?

@wonderofscience But does it ever catch it?
