Chemotaxis
What is that?
Wikipedia: Chemotaxis is a kind of taxis, in which bodily cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by swimming towards the highest concentration of food molecules, or to flee from poisons (for example, phenol). In multicellular organisms, chemotaxis is critical to development as well as normal function.
Ain't it awesome?!
1st video:
This is an example of what is Chemotaxis, there you can see a Neutrophil phagocyting a Bacterium, the Bacterium is the small cell who is chased by the big one, the Neutrophil. This Neutrophil is out of blood, and his movements (and also the bacterium ones) are due to chemical attraction, that is Chemotaxis.
The round particles are just obstacles put to see how strong is the attraction, I think.
Isn't it amazing?
Some scientific-games can be done with this, and of course they are done, and that's why the 2nd video comes:
2nd video:
Hey, that was funny!
We got A FEW thousands of thousands of them in a single drop of blood!
That's whata you learn going to Physics' Saturdays, in the Universitat Autònoma de Barcelona.
Sorry, I forgot: Those videos are accelerated.

ooooooooo
what a shame I was at the bacterium side.
But thanks for it, you won't go to the bed without learning anything more
Thanks Psico for your very first comment, and thanks Ariel for your very first mistake-detection.
I would say:
You won't go sleep without visiting my blog!
Hey guys
That's cool, isn't it?
I'd like you to show us more videos like those ones.
I'll be waiting for them.
I won't go sleep without chemotaxing ya blog.
hey urben randolph!
just write chemotaxis on your youtoube search bar.
the coolest are those two I put on my blog, but there are some more that are interesting too.
see you soon!
